Biography of C. Rollins Hanlon, MD, FACS, Past-Director of the ACS, now available
The American College of Surgeons (ACS) recently published a new biography of C. Rollins Hanlon, MD, FACS, ACS Past-Director, a seminal figure in the history of surgery and the College, titled The Conscience of Surgery: C. Rollins Hanlon, MD, FACS. Written by David L. Nahrwold, MD, FACS, this account examines the life of the erudite, principled cardiothoracic surgeon and innovator, who co-developed the Blalock-Hanlon operation with Alfred P. Blalock, MD, FACS.
The book covers every aspect of Dr. Hanlon’s life—from his boyhood in Baltimore, MD, to his quest to be the best clinician and surgeon-scientist, to his views on the government’s increasing influence on the delivery of surgical care, and to his undying love of the written word. For many surgeons, Dr. Hanlon was the embodiment of what it means to be a Fellow of the ACS.
“I got to know [Dr. Hanlon] as a person and a professional during my stint as the Interim Director of the ACS in 1999 when he was ‘retired’ and serving as Executive Consultant,” Dr. Nahrwold writes in the book’s preface. “He insisted that the mission of the College was to advance the ethical and competent practice of surgery and not to improve the financial well-being of surgeons.”
Throughout his career, Dr. Hanlon’s mentors, colleagues, and students included many eminent surgeons at Johns Hopkins Medical School, Baltimore, MD; Cincinnati General Hospital, OH; and the University of California, San Francisco. He trained under Dean DeWitt Lewis, Walter E. Dandy, Howard C. Naffziger, Warfield “Monty” Firor, and Mont Reid (all MD, FACS). He worked alongside William P. Longmire, MD, FACS; Dr. Blalock; and Mark C. Ravitch, MD, FACS; and his residents and interns at St. Louis University, MO, included Vallee Willman, Theodore Cooper, Theodore Dubuque, and William Stoneman (all MD, FACS), among others.
Dr. Hanlon served in the U.S. Navy in World War II, and followed with a distinguished career at Johns Hopkins and at St. Louis University, where, as chair of surgery, he developed the institution’s cardiac research capabilities, which helped to pioneer early open-heart and heart transplant procedures.
Dr. Hanlon became a Fellow of the College in 1953 and served as the ACS Director for 17 years (1969–1986), making him the longest-serving Director to date. Additionally, he served on the Board of Regents and as the ACS President (1985–1986). After retirement, he stayed on as ACS Executive Consultant, offering his sage advice to his successors, including Paul A. Ebert, MD, FACS; Samuel Wells, MD, FACS; Dr. Nahrwold; Thomas R. Russell, MD, FACS; and David B. Hoyt, MD, FACS. Through these positions, Dr. Hanlon had a profound effect on the direction and philosophy of the College, including in philanthropic endeavors and the establishment of the ACS Archives. He received the first ACS Lifetime Achievement Award in 2010.
“Hanlon’s integrity, faith, hard work, and service to others led him to become a role model for physicians and laypersons alike. These attributes also drove his brilliant career as an innovative surgeon, leadership in academic and organized medicine, and reputation as a humanist and ethicist,” Dr. Narhwold concludes in the preface. “Before he died I knew that I must write his biography to expose his principled life, his goodness, and his devotion to surgery and to surgeons, especially young surgeons, with the hope that they and others will find his life worthy of study and emulation.”
Dr. Nahrwold is Emeritus Professor of Surgery at Northwestern University Feinberg School of Medicine, Chicago, IL, where he was the Loyal and Edith Davis Professor and Chairman, department of surgery, and surgeon-in-chief, Northwestern Memorial Hospital. He is a recipient of the College’s highest honor—the Distinguished Service Award.
Dr. Nahrwold is author of A Mirror Reflecting Surgery, Surgeons, and their College: The Bulletin of the American College of Surgeons, and co-author, with Peter J. Kernahan, MD, PhD, FACS, of A Century of Surgeons and Surgery: The American College of Surgeons 1913–2012.
The Conscience of Surgery: C. Rollins Hanlon, MD, FACS, is available for $15.95 on the ACS E-Store at web4.facs.org/eBusiness/ProductCatalog/Product.aspx?ID=1060 and on amazon.com.

Heidi Nelson, MD, FACS, named Medical Director of ACS Cancer Programs
The American College of Surgeons (ACS) recently announced that Heidi Nelson, MD, FACS, a colorectal surgeon from Rochester, MN, will be joining the ACS Division of Research and Optimal Patient Care (DROPC) as Medical Director, Cancer Programs, succeeding David P. Winchester, MD, FACS, as he transitions from the position he has served in for more than 30 years. Dr. Nelson comes to the ACS from her position as chair, and vice-chair for research, department of surgery, Mayo Clinic, as well as professor of surgery, Mayo Clinic College of Medicine and Science, Rochester. She has master’s faculty privileges in clinical and translation science at the Mayo Clinic Graduate School of Biomedical Sciences and the Mayo Clinic College of Medicine and Science.
Dr. Nelson received a bachelor’s degree from Western Washington University, Bellingham, and her medical degree from the University of Washington School of Medicine, Seattle. She completed an internship and residency in general surgery at Oregon Health & Science University, Portland, where she also served as an American Cancer Society Fellow. She then went to the Mayo Clinic College of Medicine and Science, where she was a colon and rectal surgery fellow and completed a research fellowship. Dr. Nelson returned to the University of Washington, where she was a Leo Hirsch Traveling Fellow.
Dr. Nelson has received numerous awards and held membership in many professional organizations, including the American Society of Colon and Rectal Surgeons (ASCRS), the Mayo Clinic Board of Governors, the Society of Surgical Oncology, and the Association of Women Surgeons, among others.
Research activities
As the Fred C. Andersen Professor for the Mayo Foundation and a consultant for Mayo Clinic’s division of colon and rectal surgery, Dr. Nelson is internationally renowned for her research in the field of colon and rectal cancer. The goal of her research activities has been to improve the duration and quality of life for these patients. These efforts have helped to reduce the impact of surgery on patients with early-stage disease through the safe introduction of laparoscopic and minimally invasive surgical approaches. Her work also has helped to reduce the cancer burden in patients with locally advanced and recurrent rectal cancer through studies examining the role of complex operations and intraoperative radiation therapy. Dr. Nelson’s work has been funded by the National Institutes of Health, the American Cancer Society, the ASCRS, and many other organizations. In addition to her clinical activities, she has led the Center for Individualized Medicine Microbiome Program at the Mayo Clinic, where she conducts, presents, and publishes research on the human microbiome and its connection to health and disease.
Leadership
Dr. Nelson brings a wealth of experience from leading others and establishing results-oriented teams. She has mentored trainees and investigators and has served as an editor and publisher for high-impact journals. She also has been extensively involved with the ACS throughout her career—Dr. Nelson became an ACS Fellow in 1993 and has served as former Director, ACS Clinical Research Program; former co-chair, ACS Oncology Group; and as a member, Commission on Cancer Executive Committee.
Dr. Nelson started working with the ACS in September on an initial part-time basis, overlapping with Dr. Winchester to ensure a smooth transition and continuity of leadership.
“The American College of Surgeons is excited about Dr. Nelson joining our Executive Leadership Team. Her research acumen and leadership in the cancer care community are well known and widely respected. Her addition to our team will benefit our members, our relationships with cancer care organizations, and the patients whom we serve,” said ACS Executive Director David B. Hoyt, MD, FACS.

Endoscopic vein-graft harvest equals open harvest at 3 years
CHICAGO – Patients who underwent coronary artery bypass grafting using saphenous veins harvested endoscopically had similar clinical outcomes after nearly 3 years of follow-up as those seen with patients who received vein grafts taken by open harvesting in a multicenter, randomized trial in the United States with 1,150 patients.
As expected, follow-up also showed that endoscopic vein-graft harvesting (EVH) resulted in about half the number of wound infections as did open vein-graft harvesting (OVH). This combination of similar clinical outcomes after a median 2.8 years of follow-up, as well as fewer leg-wound adverse events, makes EVH “the preferred vein-harvesting modality,” Marco A. Zenati, MD, said at the American Heart Association scientific sessions.
Although patients far and away prefer EVH because of the reduced pain and faster healing, questions about its clinical efficacy when compared with that of OVH have lingered. That’s because observational data published almost a decade ago taken from the PREVENT IV (Project of Ex-Vivo Vein Graft Engineering via Transfection IV) trial suggested that patients who underwent coronary artery bypass grafting (CABG) using vein grafts collected by EVH had more vein-graft failures after 12-18 months and a higher rate of death, MI, or need for revascularization after 3 years, compared with patients treated using OVH (N Engl J Med. 2009 July 16;361[3]:235-44).
The results from the prospective, randomized trial reported by Dr. Zenati “take the cloud away from endovascular vein-graft harvesting that PREVENT IV had made,” commented Timothy J. Gardner, MD, a cardiac surgeon who chaired the session.
“I think this answers the question,” commented Marc Ruel, MD, a professor of surgery and the chief of cardiac surgery at the University of Ottawa. “The results show that endoscopic harvesting of vein grafts is as good as open harvesting for preventing major adverse cardiac events, which is the goal of CABG. This is a definitive trial, with no trend toward more events with endoscopic harvested vein grafts,” said Dr. Ruel, the designated discussant for Dr. Zenati’s report.
However, the study did have some significant limitations, Dr. Ruel added. The new, randomized trial, run at 16 U.S. VA cardiac surgery centers, exclusively used surgeons who were experts in endovascular vein harvesting, which could have meant that they and their surgical teams were not as expert in open vein harvesting, he said. Also, in the broader context of CABG and conduit selection, new evidence suggests the superiority of pedicled vein grafts (Ann Thoracic Surg. 2017 Oct;104[4]1313-17), and “we could also do better by using the radial artery” rather than a saphenous vein graft, Dr. Ruel said. He cited a meta-analysis published in 2018 that showed the superiority of CABG when it combined an internal thoracic artery graft with a radial artery graft rather than with a vein graft (N Engl J Med. 2018 May 31;378[22]:2069-77).
“The operation of the future is not necessarily what you saw” in Dr. Zenati’s study, Dr. Ruel cautioned.
The results Dr. Zenati reported came from the REGROUP (Randomized End-Vein Graft Prospective) trial, which enrolled patients who underwent CABG during 2014-2017. All patients received an internal thoracic artery graft and were randomized to receive additional saphenous vein grafts with the conduits collected either by the EVH or OVH method. The study’s primary endpoint of all-cause death, nonfatal MI, or need for repeat revascularization after a median follow-up of 2.8 years occurred in 14% of the patients who received vein grafts with EVH and in 16% of the patients who received grafts with OVH, a difference that was not statistically significant, reported Dr. Zenati, a professor of surgery at Harvard Medical School in Boston and the chief of cardiothoracic surgery for the VA Boston Health System. The incidence of wound infection was 3.1% in the OVH patients and 1.4% in the EVH patients, a difference that came close to but did not reach statistical significance. Concurrently with Dr. Zenati’s report, an article with the results appeared online (N Engl J Med. 2018 Nov 11. doi: 0.1056/NEJMoa1812390).
The REGROUP trial did not collect data on vein-graft patency following CABG. The investigators were concerned about having enough patients return for follow-up angiography to produce a meaningful result for this endpoint, and they believed that the clinical endpoint they used sufficed for demonstrating equivalence of the two harvesting methods, Dr. Zenati said during his talk.
“The more arterial conduit used in CABG, the better the durability of the grafts, but often surgeons use vein grafts because there is not enough arterial conduit,” commented Donald M. Lloyd-Jones, MD, professor and chair of preventive medicine at Northwestern University in Chicago.* “The recovery from endoscopic vein-graft harvesting is very different from open harvesting. Endoscopic harvesting produces much less pain and infection, and recovery is much easier for patients, so it’s reassuring to see that the quality of the vein is not affected by endoscopic harvesting when done by experts,” he said.

The results from the REGROUP trial are interesting and open the field for additional comparisons of endoscopic and open saphenous vein-graft harvesting, but this trial is not the definitive answer regarding whether these two harvesting approaches produce similar results. Greater reassurance of equivalence would come from studies that included more patients and a more diverse patient population; REGROUP largely enrolled male veterans and patients with multiple comorbidities. Longer follow-up is also needed. A median follow-up of 3 years is too brief for complete reassurance that long-term patency is the same with both approaches. It would also help to have follow-up data on graft patency. Many factors besides patency can lead to differences in clinical outcomes following coronary bypass surgery.
Endoscopic vein harvesting is preferred by patients, and it results in fewer wound infections, as was confirmed in REGROUP. Because of these advantages for endoscopic harvesting, it would be great if we could definitively document that these vein grafts functioned as well as those taken with open harvesting.
Evidence now suggests that the more arterial conduits used during coronary bypass, the better. If I were having triple-vessel bypass surgery, I’d want to get two thoracic-artery bypass grafts and a radial artery graft. But studies like REGROUP are important because a majority of heart surgeons use vein grafts for several reasons including convenience. Surgeons will likely continue to use vein grafts for the foreseeable future, so we need to know whether endoscopic harvesting is an acceptable approach.

CHICAGO – Patients who underwent coronary artery bypass grafting using saphenous veins harvested endoscopically had similar clinical outcomes after nearly 3 years of follow-up as those seen with patients who received vein grafts taken by open harvesting in a multicenter, randomized trial in the United States with 1,150 patients.
As expected, follow-up also showed that endoscopic vein-graft harvesting (EVH) resulted in about half the number of wound infections as did open vein-graft harvesting (OVH). This combination of similar clinical outcomes after a median 2.8 years of follow-up, as well as fewer leg-wound adverse events, makes EVH “the preferred vein-harvesting modality,” Marco A. Zenati, MD, said at the American Heart Association scientific sessions.
Although patients far and away prefer EVH because of the reduced pain and faster healing, questions about its clinical efficacy when compared with that of OVH have lingered. That’s because observational data published almost a decade ago taken from the PREVENT IV (Project of Ex-Vivo Vein Graft Engineering via Transfection IV) trial suggested that patients who underwent coronary artery bypass grafting (CABG) using vein grafts collected by EVH had more vein-graft failures after 12-18 months and a higher rate of death, MI, or need for revascularization after 3 years, compared with patients treated using OVH (N Engl J Med. 2009 July 16;361[3]:235-44).
The results from the prospective, randomized trial reported by Dr. Zenati “take the cloud away from endovascular vein-graft harvesting that PREVENT IV had made,” commented Timothy J. Gardner, MD, a cardiac surgeon who chaired the session.
“I think this answers the question,” commented Marc Ruel, MD, a professor of surgery and the chief of cardiac surgery at the University of Ottawa. “The results show that endoscopic harvesting of vein grafts is as good as open harvesting for preventing major adverse cardiac events, which is the goal of CABG. This is a definitive trial, with no trend toward more events with endoscopic harvested vein grafts,” said Dr. Ruel, the designated discussant for Dr. Zenati’s report.

‘Organoid technology’ poised to transform cancer care
BOSTON– Imagine being able to .
The implications are nearly endless. To start, chemotherapy and radiation options could be screened in vitro, much like culture and sensitivity testing of bacteria, to find a patient’s best option. Tumor cultures could be banked for mass screening of new cytotoxic candidates.
It’s already beginning to happen in a few research labs around the world, and it might foretell a breakthrough in cancer treatment.
After decades of failure, the trick to growing tumor cells in culture has finally been figured out. When stem cells are fished out of healthy tissue – from the crypts of the gastrointestinal lining, for instance – and put into a three-dimensional matrix culture with growth factors, they grow into little replications of the organs they came from, called “organoids;” when stem cells are pulled from cancers, they replicate the primary tumor, growing into “tumoroids” ready to be tested against cytotoxic drugs and radiation.
Philip B. Paty, MD, FACS, a colorectal surgeon and organoid researcher at Memorial Sloan Kettering Cancer Center, New York, said he is certain that the person who led the team that figured out the right culture condition – Hans Clevers, MD, PhD, a molecular genetics professor at the University of Utrecht (the Netherlands) – is destined for a Nobel Prize.
Dr. Paty took a few minutes at the annual clinical congress of the American College of Surgeons to explain in an interview why, and what ‘organoid technology’ will likely mean for cancer treatment in a few years.
“The ability to grow and sustain cancer means that we now can start doing real science on human tissues. We could never do this before. We’ve been treating cancer without being able to grow tumors and study them.” The breakthrough opens the door to “clinical trials in a dish,” and will likely take personalized cancer treatment to a new level, he said.
“It remains to be proven that “organoid technology “can change outcomes for patients, but those studies are likely coming,” said Dr. Paty, who investigates tumoroid response to radiation in his own lab work.

REPORTING FROM THE ACS CLINICAL CONGRESS
MIS for cervical cancer: Is it not for anyone or not for everyone?
Shock waves moved through the gynecologic oncology world on Oct. 31, 2018, when the New England Journal of Medicine published two papers on survival outcomes for women undergoing surgery for early stage cervical cancer.
The first was a randomized controlled trial of laparotomy and minimally invasive surgery (MIS) for radical hysterectomy called the LACC trial.1 In the multicenter, international trial of 631 women, the primary objective was disease-specific survival (cervical cancer–related deaths) and was powered to detect noninferiority of the MIS approach when compared with laparotomy. The trial was closed early when investigators noted a lower than expected rate of 3-year, disease-free survival (91% vs. 97%) from cervical cancer in the MIS group, which was made up of 84% laparoscopic and 16% robotic approaches, versus laparotomy. There were 19 deaths in the MIS group observed versus three in the laparotomy group. The conclusions of the trial were that MIS surgery is associated with inferior cervical cancer survival.
In the second study, authors analyzed data from large U.S. databases – the National Cancer Database (NCDB) and the Surveillance, Epidemiology, and End Results (SEER) Program – to collect all-cause mortality for patients with early-stage cervical cancer who had undergone radical hysterectomy during 2010-2013.2 Among 2,461 observed results, 1,225 had undergone MIS surgery with the majority (79.8%) via robotic-assistance. Women undergoing MIS approaches had smaller, lower grade tumors; were more likely to be white, privately insured, and of a higher income; and had surgery later in the cohort and by nonacademic centers. The researchers adjusted for risk factors with an analytic process called propensity-score weighting, which matched the groups more closely in an attempt to minimize confounders. They identified higher all-cause mortality among women who were treated with an MIS approach, compared with those treated with laparotomy (hazard ratio, 1.65). They also observed a significant decline in the survival from cervical cancer annually that corresponded to the uptake of MIS radical hysterectomies.
In the wake of these publications, many concluded that gynecologic oncologists should no longer offer a minimally invasive approach for radical hysterectomy. Certainly level I evidence published in a highly influential journal is compelling, and the consistency in findings over two studies adds further weight to the results. However, was this the correct conclusion to draw from these results? Surgeons who had been performing MIS radical hysterectomies for many years with favorable outcomes are challenging this and are raising questions about external generalizability and whether these findings were driven by the surgery itself or by the surgeon.
The studies’ authors proposed hypotheses for their results that implicate the surgical route rather than the surgeon; however, these seem ad hoc and not well supported by data, including the authors’ own data. The first was the hypothesis that cervical tumors were being disrupted and disseminated through the use of uterine manipulators in MIS approaches. However, cervical cancers are fairly routinely “disrupted” by preoperative cone biopsies, loop electrosurgical excision procedures (LEEP), and sharp biopsies, which are arguably more invasive than placement of a manipulator. Uterine manipulators routinely are used in endometrial cancer surgeries, in which the manipulator is embedded within the tumor, without an associated negative survival effect in randomized trials.3 Additionally, not all surgeons utilize manipulators for radical hysterectomies, and these studies did not measure or report on their use; therefore, it is impossible to know whether, and by what magnitude, manipulators played a role. Finally, if uterine manipulators are the explanation for inferior survival, surely the recommendation should be to discourage their use, rather than abandon the MIS approach all together.
The other explanation offered was exposure of the tumor to CO2 gas. This seems an even less plausible explanation because CO2 gas is routinely used in MIS cancer surgeries for endometrial, prostate, gastric, and colorectal surgeries and is used as insufflation for malignant interventional endoscopies without a significant deleterious effect. Additionally, the cervix is not exposed to CO2 until colpotomy at the procedure’s end – and only briefly. The in vitro studies implicating a negative effect of simulated CO2 pneumoperitoneum are neither compelling nor consistent.4,5
I would like to propose another hypothesis for the results: surgical proficiency. Surgery, unlike medical interventions, is not a simple variable that is dichotomous – performed or not. Surgeons do not randomly select operative approaches for patients. We select surgical approaches based on patients’ circumstances and surgeon factors, including our own mastery of the various techniques. and any surgeon recognizes this if he or she has observed more than one surgeon or has attempted a procedure via different routes. While some procedures, such as extrafascial hysterectomy for endometrial cancer, are relatively straightforward and surgeon capabilities are more equitable across different approaches, cervical cancer surgery is quite different.
Early-stage cervical cancer primarily exerts radial growth into the cervical stroma and parametria. Curative surgical excision requires broadly negative margins through this tissue, a so called “radical hysterectomy.” The radicality of hysterectomy has been categorized in stages, acknowledging that different sized lesions require different volumes of parametrial resection to achieve adequate clearance from the tumor.6 In doing so, the surgeon must skeletonize and mobilize the distal ureters, cardinal ligament webs, and uterosacral ligaments. These structures are in close proximity to major vascular and neural structures. Hence, the radical hysterectomy is, without dispute, a technically challenging procedure.
Minimally invasive surgery further handicaps the surgeon by eliminating manual contact with tissue, and relying on complex instrumentation, electrosurgical modalities, and loss of haptics. The learning curve for MIS radical hysterectomy is further attenuated by their relative infrequency. Therefore, it makes sense that, when the MIS approach is randomly assigned to surgeons (such as in the LACC trial) or broadly and independently applied (as in the retrospective series), one might see variations in skill, quality, and outcomes, including oncologic outcomes.
The retrospective study by Melamed et al. acknowledged that surgeon skill and volume may contribute to their findings but stated that, because of the nature of their source data, they were unable to explain why they observed their results. The LACC trial attempted to overcome the issue of surgeon skill by ensuring all surgeons were from high-volume sites and had videos reviewed of their cases. However, the videos were chosen by the surgeons themselves and not available for audit in the study’s supplemental material. The LACC trial was conducted over a 9-year period across 33 sites and enrolled a total of 631 subjects. This equates to an enrollment of approximately two patients per site per year and either reflects extremely low-volume sites or highly selective patient enrollment. If the latter, what was different about the unenrolled patients and what was the preferred chosen route of surgery for them?
All 34 recurrences occurred in patients from just 14 of the 33 sites in the LACC trial. That means that less than half of the sites contributed to all of the recurrences. The authors provided no details on the specific sites, surgeons, or accrual rates in their manuscript or supplemental materials. Therefore, readers are unable to know what was different about those sites; whether they contributed the most patients and, therefore, the most recurrences; or whether they were low-volume sites with lower quality.
While margin status, positive or negative, was reported, there was no data captured regarding volume of resected parametrial tissue, or relative distance from tumor to margin, both of which might provide the reader with a better appraisal of surgeon proficiency and consistency in radicality of the two approaches. The incidence of locoregional (pelvic) recurrences were higher in the MIS arm, which is expected if there were inadequate margins around the laparoscopically resected tumors.
Finally, the authors of the LACC trial observed equivalent rates of postoperative complications between the laparotomy and MIS groups. The main virtue for MIS approaches is the reduction in perioperative morbidity. To observe no perioperative morbidity benefit in the MIS group is a red flag suggesting that these surgeons may not have achieved proficiency with the MIS approach.
Despite these arguments, the results of these studies should be taken seriously. Clearly, it is apparent that preservation of oncologic outcomes is not guaranteed with MIS radical hysterectomy, and it should not be the chosen approach for all patients and all surgeons. However, rather than entirely abandoning this less morbid approach, I would argue that it is a call to arms for gynecologic oncologists to self-evaluate. We should know our own data with respect to case volumes, perioperative complications, and cancer-related recurrence and death.
Perhaps MIS radical hysterectomies should be consolidated among high-volume surgeons with demonstrated good outcomes? Just as has been done for rectal cancer surgery with positive effect, we should establish accredited centers of excellence.7 We also need to improve the training of surgeons in novel, difficult techniques, as well as enhance the sophistication of MIS equipment such as improved instrumentation, haptics, and vision-guided surgery (for example, real-time intraoperative assessment of the tumor margins).
Let’s not take a wholesale step backwards to the surgical approaches of a 100 years ago just because they are more straightforward. Let’s do a better job of advancing the quality of what we do for our patients in the future.

Shock waves moved through the gynecologic oncology world on Oct. 31, 2018, when the New England Journal of Medicine published two papers on survival outcomes for women undergoing surgery for early stage cervical cancer.
The first was a randomized controlled trial of laparotomy and minimally invasive surgery (MIS) for radical hysterectomy called the LACC trial.1 In the multicenter, international trial of 631 women, the primary objective was disease-specific survival (cervical cancer–related deaths) and was powered to detect noninferiority of the MIS approach when compared with laparotomy. The trial was closed early when investigators noted a lower than expected rate of 3-year, disease-free survival (91% vs. 97%) from cervical cancer in the MIS group, which was made up of 84% laparoscopic and 16% robotic approaches, versus laparotomy. There were 19 deaths in the MIS group observed versus three in the laparotomy group. The conclusions of the trial were that MIS surgery is associated with inferior cervical cancer survival.
In the second study, authors analyzed data from large U.S. databases – the National Cancer Database (NCDB) and the Surveillance, Epidemiology, and End Results (SEER) Program – to collect all-cause mortality for patients with early-stage cervical cancer who had undergone radical hysterectomy during 2010-2013.2 Among 2,461 observed results, 1,225 had undergone MIS surgery with the majority (79.8%) via robotic-assistance. Women undergoing MIS approaches had smaller, lower grade tumors; were more likely to be white, privately insured, and of a higher income; and had surgery later in the cohort and by nonacademic centers. The researchers adjusted for risk factors with an analytic process called propensity-score weighting, which matched the groups more closely in an attempt to minimize confounders. They identified higher all-cause mortality among women who were treated with an MIS approach, compared with those treated with laparotomy (hazard ratio, 1.65). They also observed a significant decline in the survival from cervical cancer annually that corresponded to the uptake of MIS radical hysterectomies.
In the wake of these publications, many concluded that gynecologic oncologists should no longer offer a minimally invasive approach for radical hysterectomy. Certainly level I evidence published in a highly influential journal is compelling, and the consistency in findings over two studies adds further weight to the results. However, was this the correct conclusion to draw from these results? Surgeons who had been performing MIS radical hysterectomies for many years with favorable outcomes are challenging this and are raising questions about external generalizability and whether these findings were driven by the surgery itself or by the surgeon.
The studies’ authors proposed hypotheses for their results that implicate the surgical route rather than the surgeon; however, these seem ad hoc and not well supported by data, including the authors’ own data. The first was the hypothesis that cervical tumors were being disrupted and disseminated through the use of uterine manipulators in MIS approaches. However, cervical cancers are fairly routinely “disrupted” by preoperative cone biopsies, loop electrosurgical excision procedures (LEEP), and sharp biopsies, which are arguably more invasive than placement of a manipulator. Uterine manipulators routinely are used in endometrial cancer surgeries, in which the manipulator is embedded within the tumor, without an associated negative survival effect in randomized trials.3 Additionally, not all surgeons utilize manipulators for radical hysterectomies, and these studies did not measure or report on their use; therefore, it is impossible to know whether, and by what magnitude, manipulators played a role. Finally, if uterine manipulators are the explanation for inferior survival, surely the recommendation should be to discourage their use, rather than abandon the MIS approach all together.
The other explanation offered was exposure of the tumor to CO2 gas. This seems an even less plausible explanation because CO2 gas is routinely used in MIS cancer surgeries for endometrial, prostate, gastric, and colorectal surgeries and is used as insufflation for malignant interventional endoscopies without a significant deleterious effect. Additionally, the cervix is not exposed to CO2 until colpotomy at the procedure’s end – and only briefly. The in vitro studies implicating a negative effect of simulated CO2 pneumoperitoneum are neither compelling nor consistent.4,5
I would like to propose another hypothesis for the results: surgical proficiency. Surgery, unlike medical interventions, is not a simple variable that is dichotomous – performed or not. Surgeons do not randomly select operative approaches for patients. We select surgical approaches based on patients’ circumstances and surgeon factors, including our own mastery of the various techniques. and any surgeon recognizes this if he or she has observed more than one surgeon or has attempted a procedure via different routes. While some procedures, such as extrafascial hysterectomy for endometrial cancer, are relatively straightforward and surgeon capabilities are more equitable across different approaches, cervical cancer surgery is quite different.
Early-stage cervical cancer primarily exerts radial growth into the cervical stroma and parametria. Curative surgical excision requires broadly negative margins through this tissue, a so called “radical hysterectomy.” The radicality of hysterectomy has been categorized in stages, acknowledging that different sized lesions require different volumes of parametrial resection to achieve adequate clearance from the tumor.6 In doing so, the surgeon must skeletonize and mobilize the distal ureters, cardinal ligament webs, and uterosacral ligaments. These structures are in close proximity to major vascular and neural structures. Hence, the radical hysterectomy is, without dispute, a technically challenging procedure.
Minimally invasive surgery further handicaps the surgeon by eliminating manual contact with tissue, and relying on complex instrumentation, electrosurgical modalities, and loss of haptics. The learning curve for MIS radical hysterectomy is further attenuated by their relative infrequency. Therefore, it makes sense that, when the MIS approach is randomly assigned to surgeons (such as in the LACC trial) or broadly and independently applied (as in the retrospective series), one might see variations in skill, quality, and outcomes, including oncologic outcomes.
The retrospective study by Melamed et al. acknowledged that surgeon skill and volume may contribute to their findings but stated that, because of the nature of their source data, they were unable to explain why they observed their results. The LACC trial attempted to overcome the issue of surgeon skill by ensuring all surgeons were from high-volume sites and had videos reviewed of their cases. However, the videos were chosen by the surgeons themselves and not available for audit in the study’s supplemental material. The LACC trial was conducted over a 9-year period across 33 sites and enrolled a total of 631 subjects. This equates to an enrollment of approximately two patients per site per year and either reflects extremely low-volume sites or highly selective patient enrollment. If the latter, what was different about the unenrolled patients and what was the preferred chosen route of surgery for them?
All 34 recurrences occurred in patients from just 14 of the 33 sites in the LACC trial. That means that less than half of the sites contributed to all of the recurrences. The authors provided no details on the specific sites, surgeons, or accrual rates in their manuscript or supplemental materials. Therefore, readers are unable to know what was different about those sites; whether they contributed the most patients and, therefore, the most recurrences; or whether they were low-volume sites with lower quality.
While margin status, positive or negative, was reported, there was no data captured regarding volume of resected parametrial tissue, or relative distance from tumor to margin, both of which might provide the reader with a better appraisal of surgeon proficiency and consistency in radicality of the two approaches. The incidence of locoregional (pelvic) recurrences were higher in the MIS arm, which is expected if there were inadequate margins around the laparoscopically resected tumors.
Finally, the authors of the LACC trial observed equivalent rates of postoperative complications between the laparotomy and MIS groups. The main virtue for MIS approaches is the reduction in perioperative morbidity. To observe no perioperative morbidity benefit in the MIS group is a red flag suggesting that these surgeons may not have achieved proficiency with the MIS approach.
Despite these arguments, the results of these studies should be taken seriously. Clearly, it is apparent that preservation of oncologic outcomes is not guaranteed with MIS radical hysterectomy, and it should not be the chosen approach for all patients and all surgeons. However, rather than entirely abandoning this less morbid approach, I would argue that it is a call to arms for gynecologic oncologists to self-evaluate. We should know our own data with respect to case volumes, perioperative complications, and cancer-related recurrence and death.
Perhaps MIS radical hysterectomies should be consolidated among high-volume surgeons with demonstrated good outcomes? Just as has been done for rectal cancer surgery with positive effect, we should establish accredited centers of excellence.7 We also need to improve the training of surgeons in novel, difficult techniques, as well as enhance the sophistication of MIS equipment such as improved instrumentation, haptics, and vision-guided surgery (for example, real-time intraoperative assessment of the tumor margins).

‘Watch and wait’ good for most – but not all – rectal cancers
BOSTON –
was established over a decade ago, and widely adopted since then. The idea is to hold off on surgery after a complete response to chemotherapy and radiation, to see if the patient really needs it.
While most do not, tumors regrow in 20%-30%, and when they come back, they tend to be aggressive, with poor outcomes. Patients in those situations would have been better off with upfront surgery.
The problem right now is that there’s no way to predict who will be cured by neoadjuvant therapy and whose tumor will come back, said Philip Paty, MD. FACS, a colorectal surgeon at Memorial Sloan Kettering Cancer Center, New York.
“There are some who are probably harmed by the watch-and-wait paradigm. The risk of local regrowth is hardbaked into [the model]; we haven’t been able to eliminate it,” he said at the annual clinical congress of the American College of Surgeons..
Dr. Paty is one of many investigators working to identify those at risk. In the meantime, watch-and-wait patients need to be followed closely, particularly in the first 2 years. Surgery is the best option at the first sign of regrowth. Dr. Paty explained his follow-up protocol, as well as the current state of watch and wait for low rectal cancer, in an interview at the meeting.
He also talked about overcoming hurdles. The risk of surgery, including permanent bowel and sexual dysfunction, is so great “that many patients latch onto watch and wait and won’t let go. They don’t come back for follow-up, or resist the idea of surgery even if it’s needed,” he said.

EXPERT ANALYSIS FROM THE ACS CLINICAL CONGRESS
How to slash colorectal surgery infection rates
BOSTON – driven mostly by a reduction in deep organ space infections from 5.5% to 1.7%.
It was a remarkable finding that got the attention of attendees at the annual clinical congress of the American College of Surgeons. The Cleveland Clinic had been an outlier, in the wrong direction, compared with other centers, and administrators wanted a solution.
I. Emre Gorgun, MD, FACS, a colorectal surgeon and quality improvement officer at Cleveland Clinic, led the search for evidence-based interventions. Eventually, big changes were made to perioperative antibiotics, mechanical bowel prep, preop shower routines, and intraoperative procedures. The efforts paid off (Dis Colon Rectum. 2018 Jan;61[1]:89-98).
To help surgeons lower their own infection rates, Dr. Gorgun agreed to an interview at the meeting to explain exactly what was done.
There was resistance at first from surgeons who wanted to stick with their routines, but they came around once they were shown the data backing the changes. Eventually, “everyone was on board. We believe in this,” Dr. Gorgun said.

How, and when, to use fat grafting for scars
BOSTON – according to Benjamin Levi, MD, director of the burn/wound and regenerative medicine laboratory at the University of Michigan, Ann Arbor.
Some corners of the Internet tout it as “some sort of magic stem cell surgery,” Dr. Levi said, but in reality, for scar surgeons, it’s just another useful tool in the armamentarium, one that excels at filling skin depressions due to underlying tissue loss, whether from burns, trauma, or surgery. Unlike hyaluronic acid and other options, fat grafts last; about half of injected adipocytes remain indefinitely. Fat grafting might also help soften scars, he said.
To get the most out of the procedure, of course, it has to be done correctly, so Dr. Levi took a few minutes at the annual clinical congress of the American College of Surgeons to share his tips on harvesting and spinning down fat grafts, injecting adipocytes, and other matters. Although the concepts of fat grafting are straightforward, the techniques are a bit tricky. Dr. Levi hoped his treatment pearls would help other physicians, especially those considering adding fat grafting to their practice.

EXPERT ANALYSIS FROM THE ACS CLINICAL CONGRESS
High rates of prescription opioid, benzodiazepine use observed in chronic liver disease
SAN FRANCISCO – .
“Middle-aged individuals and those with a background of substance abuse and mental health conditions appear to have highest rates of use and represent populations for which targeted interventions to curb use could be highest yield,” lead study author Monica Konerman, MD, said in an interview in advance of the annual meeting of the American Association for the Study of Liver Diseases.
In an effort to better understand the rates of prescription opioid and benzodiazepine use in chronic liver disease, Dr. Konerman, director of the Michigan Medicine NAFLD Clinic at the University of Michigan, Ann Arbor, and her colleagues drew from the Truven Health Analytics Marketscan databases from 2009 to 2015. They limited the analysis to individuals with drug coverage who had chronic hepatitis C (HCV) without cirrhosis, cirrhosis, congestive heart failure (CHF), or chronic obstructive pulmonary disease (COPD), and examined pharmacy files for outpatient prescriptions.
Dr. Konerman reported data from 210,191 patients with HCV, 79,332 with cirrhosis, 766,840 with CHF, and 1,438,798 with COPD. Their median age was 59 years, and 51% were female. In per person-years, the prevalence of prescription opioid use was 25% among patients with chronic HCV, 53% among patients with cirrhosis, 26% among those with CHF, and 24% among those with COPD. At the same time, in per person-years, the prevalence of benzodiazepine use was 12% among patients with chronic HCV, 21% among patients with cirrhosis, 12% among those with CHF, and 13% among those with COPD. Use of opioids was greatest in adults 40-59 years of age (P less than .001). High-dose opioid use, defined as 100 opioid morphine equivalents per day or greater, occurred in 23% of those with cirrhosis and in 22% of those with HCV.
“The significant increase in rates of use in chronic liver disease, compared to other chronic conditions was remarkable, particularly given that patients with liver disease are at higher risk for adverse consequences of use due to hepatic metabolism of these medications,” Dr. Konerman said.
She went on to acknowledge “inherent limitations to studies that are secondary database analyses that rely on diagnosis codes for categorization of disease with potential for both over and under classification. We also did not capture inpatient prescriptions,” she said.

“Middle-aged individuals and those with a background of substance abuse and mental health conditions appear to have highest rates of use and represent populations for which targeted interventions to curb use could be highest yield,” lead study author Monica Konerman, MD, said in an interview in advance of the annual meeting of the American Association for the Study of Liver Diseases.
In an effort to better understand the rates of prescription opioid and benzodiazepine use in chronic liver disease, Dr. Konerman, director of the Michigan Medicine NAFLD Clinic at the University of Michigan, Ann Arbor, and her colleagues drew from the Truven Health Analytics Marketscan databases from 2009 to 2015. They limited the analysis to individuals with drug coverage who had chronic hepatitis C (HCV) without cirrhosis, cirrhosis, congestive heart failure (CHF), or chronic obstructive pulmonary disease (COPD), and examined pharmacy files for outpatient prescriptions.
Dr. Konerman reported data from 210,191 patients with HCV, 79,332 with cirrhosis, 766,840 with CHF, and 1,438,798 with COPD. Their median age was 59 years, and 51% were female. In per person-years, the prevalence of prescription opioid use was 25% among patients with chronic HCV, 53% among patients with cirrhosis, 26% among those with CHF, and 24% among those with COPD. At the same time, in per person-years, the prevalence of benzodiazepine use was 12% among patients with chronic HCV, 21% among patients with cirrhosis, 12% among those with CHF, and 13% among those with COPD. Use of opioids was greatest in adults 40-59 years of age (P less than .001). High-dose opioid use, defined as 100 opioid morphine equivalents per day or greater, occurred in 23% of those with cirrhosis and in 22% of those with HCV.
