Case Report

A 60-year-old Cambodian woman presented with recurrent fever (temperature, up to 38.8°C) 7 months after receiving a kidney transplant secondary to polycystic kidney disease. Fever was attributed to recurrent pyelonephritis of the native kidneys while on mycophenolate mofetil, tacrolimus, and prednisone. As a result, she underwent a bilateral native nephrectomy and was found to have peritoneal nodules. Pathology of both native kidneys and peritoneal tissue revealed caseating granulomas and acid-fast bacilli (AFB) diagnostic for kidney and peritoneal tuberculosis (TB). She had no history of TB, and a TB skin test (purified protein derivative [PPD]) upon entering the United States from Cambodia a decade earlier was negative. Additionally, her pretransplantation PPD was negative.

Treatment with isoniazid, ethambutol, pyrazinamide, and levofloxacin was initiated immediately upon diagnosis, and all of her immunosuppressive medications—mycophenolate mofetil, tacrolimus, and prednisone—were discontinued. Her symptoms subsided within 1 week, and she was discharged from the hospital. Over the next 2 months, her immunosuppressive medications were restarted, and her TB medications were periodically discontinued by the Tuberculosis Control Program at the Department of Health (Philadelphia, Pennsylvania) due to severe thrombocytopenia. During this time, she was closely monitored twice weekly in the clinic with blood draws performed weekly.

Approximately 10 weeks after initiation of treatment, she noted recurrent subjective fever (temperature, up to 38.8°C) and painful lesions on the right side of the flank, left breast, and left arm of 3 days’ duration. Physical examination revealed a warm, dull red, tender nodule on the right side of the flank (Figure 1) and subcutaneous nodules with no overlying skin changes on the left breast and left arm. A biopsy of the lesion on the right side of the flank was performed, which resulted in substantial purulent drainage. Histologic analysis showed an inflammatory infiltrate within the deep dermis composed of neutrophils, macrophages, and giant cells, indicative of suppurative granulomatous dermatitis (Figure 2). Ziehl-Neelsen stain demonstrated rare AFB within the cytoplasm of macrophages, suggestive of Mycobacterium tuberculosis infection (Figure 3). A repeat chest radiograph was normal.

Clinical Presentation
Cutaneous TB is an uncommon manifestation of TB that can occur either exogenously or endogenously.¹ It tends to occur primarily in previously infected TB patients through hematogenous, lymphatic, or contiguous spread.² Due to their immunocompromised state, solid organ transplant recipients have an increased incidence of primary and reactivated latent TB reported to be 20 to 74 times greater than the general population.^3,4 One report stated the total incidence of posttransplant TB as 0.48% in the West and 11.8% in endemic regions such as India.⁵ The occurrence of cutaneous TB is rare among solid organ transplant recipients.¹ On average, a diagnosis of latent TB is made 9 months after transplantation because of the opportunistic nature of M tuberculosis in an immunosuppressed environment.⁶

TB Subtypes
Cutaneous TB can be in the form of localized disease (eg, primary tuberculous chancre, TB verrucosa cutis, lupus vulgaris, smear-negative scrofuloderma), disseminated disease (eg, disseminated TB, TB gumma, orificial TB, miliary cutaneous TB), or tuberculids (eg, papulonecrotic tuberculid, lichen scrofulosorum, erythema induratum).⁷ Due to the pustular epithelioid cell granulomas and AFB positivity of the involved cutaneous lesions, our patient’s TB can be classified as a metastatic TB abscess or gummatous TB.⁷

Metastatic TB abscess, an uncommon subtype of cutaneous TB, generally is only seen in malnourished children and notably immunocompromised individuals.^2,8,9 In these individuals, systemic failure of cell-mediated immunity enables M tuberculosis to hematogenously infect various organs of the body, resulting in alternative forms of TB, such as gummatous-type TB.¹⁰ One study reported that of the 0.1% of dermatology patients presenting with cutaneous TB, only 5.4% of these individuals had the rarer gummatous form.⁷ These metastatic TB abscesses begin as a single or multiple nontender subcutaneous nodule(s), which breaks down and softens to form a draining sinus abscess.^2,8,9 Abscesses are most commonly seen on the trunk and extremities; however, they can be found nearly anywhere on the body.⁸ The pathology of cutaneous TB lesions demonstrates caseating necrosis with epithelioid and giant cells forming a surrounding rim.⁹

Diagnosis
Diagnosis may be difficult because of the vast number of dermatologic conditions that resemble cutaneous TB, including mycoses, sarcoidosis, leishmaniasis, leprosy, syphilis, other non-TB mycobacteria, and Wegener granulomatosis.⁹ Thus, confirmatory diagnosis is made via clinical presentation, detailed history and physical examination, and laboratory tests.¹¹ These tests include the Mantoux tuberculin skin test (PPD or TST) or IFN-γ release assays (QuantiFERON-TB Gold test), identification of AFB on skin biopsy, and isolation of M tuberculosis from tissue culture or polymerase chain reaction.¹¹Given our patient’s history, clinical presentation, and the identification of mycobacteria with AFB stain, the diagnosis of cutaneous gummatous TB was confirmed.

At-Risk Populations
The recommendation for the identification of at-risk populations for latent TB testing and treatment have been clearly defined by the World Health Organization (Table).¹² Our patient met 2 of these criteria: she had been preparing for organ transplantation and was from a country with high TB burden. Such at-risk patients should be tested for a latent TB infection with either IFN-γ release assays or PPD.¹²These recommendations are supported by the American Thoracic Society, which specifies that a positive PPD test in a solid organ transplant recipient is defined as having induration greater than 5 mm.¹³ However, even with a high index of suspicion, it has been reported that as many as 75% to 80% of organ recipients who developed TB had a false-negative pretransplantation PPD due to anergy from immunosuppression.¹⁴ Given the notable risk for TB in organ transplant recipients on immunosuppressive medications, these patients should receive screening tests with high sensitivity and specificity, while controlling for possible anergy. Unfortunately, the role of anergy testing in the diagnosis of latent TB is not well defined, and thus not recommended at this time.^13,15 It is recommended to repeat PPD testing 7 to 10 days after the first test as a booster effect to rule out false-negative results.¹⁵

Finally, thrombocytopenia is an infrequent, life-threatening complication that can be acquired by immunocompromised patients on anti-TB therapy.¹⁷ Drug-induced thrombocytopenia can be caused by a variety of medications, including rifampicin, isoniazid, ethambutol, and pyrazinamide. Diagnosis of drug-induced thrombocytopenia can be confirmed only after discontinuation of the suspected drug and subsequent resolution of the thrombocytopenia.¹⁷ Our patient initially became thrombocytopenic while taking isoniazid, ethambutol, pyrazinamide, and levofloxacin. However, her platelet levels improved once the pyrazinamide was discontinued, thereby suggesting pyrazinamide-induced thrombocytopenia.

Conclusion

The risk for infectious disease reactivation in an immunocompromised patient undergoing transplant surgery is notable. Our findings emphasize the value of a comprehensive pretransplant evaluation, vigilance even when test results appear negative, and treatment of latent TB within this population.^16,18,19 Furthermore, this case illustrates a noteworthy example of a rare form of cutaneous TB, which should be considered and included in the differential for cutaneous lesions in an immunosuppressed patient.

Sarcoidosis is a systemic noncaseating granuloma­tous disease of unknown etiology. The skin is the second most common location for disease mani­festation following the lungs.¹ Cutaneous sarcoidosis is present in 35% of patients with sarcoidosis and may be further subtyped by its morphologic characteristics (eg, hyperpigmented, papular, nodular, atrophic, ulcer­ative, psoriasiform). Cutaneous sarcoidosis has an increased tendency to occur at areas of prior injury such as surgeries or tattoos.² Although sarcoidosis affects all races and sexes, it is more prevalent in women and in the black population.³ 

The clinical presentation of sarcoidosis is difficult due to its morphologic variation, allowing for a wide differential diagnosis. With our patient’s presentation of atrophic plaques, the differential diagnosis included granuloma annulare, necrobiosis lipoidica, tumid lupus erythematosus, leprosy, and sarcoidosis; however, biopsy is required for definitive diagnosis. The characteristic histopathology for cutaneous sarcoidosis includes nonca­seating granulomas (Figure, A) composed of epithelioid histiocytes with giant cells surrounded by a lympho­cytic infiltrate. Noncaseating granulomas are consid­ered specific to sarcoidosis and are present in 71% to 89% of biopsied lesions.⁴ Interestingly, our patient pre­sented with a rare subtype of atrophic ulcerative cutane­ous sarcoidosis, necrobiosis lipoidica–like sarcoidosis, which is more common in females and in the black population. It is characterized by pink to violaceous plaques with depressed centers and prominent necrotiz­ing granuloma (Figure, B) on histopathology. In a small case series, all 3 patients with necrobiosis lipoidica–like sarcoidosis were female and had systemic involvement at the time of diagnosis.⁵ 

Sarcoidosis typically is a systemic disease with only a limited number of cases presenting with isolated cutane­ous findings. Therefore, patients require a systemic evalu­ation, which may include a chest radiograph, complete blood cell count, ophthalmologic examinations, thyroid testing, and vitamin D monitoring, as well as an echocar­diogram and electrocardiogram.² 

Treatment is guided by the severity of disease. For isolated cutaneous lesions, topical or intralesional high-potency steroids have been shown to be effective.^6,7 Several studies also have shown phototherapy and laser therapy as well as surgical excision to be beneficial.^8-10 Once cutaneous lesions become disfiguring or systemic involvement is found, systemic corticosteroids or other immunomodulatory medications may be warranted.¹¹ Our patient was started on intralesional and topical high-potency steroids, which failed, and she was transitioned to methotrexate and adalimumab. Unfortunately, even with advanced therapies, our patient did not have notableresolution of the lesions.

High expression of cyclin E1 (CCNE1) was associated with resistance to treatment with palbociclib plus fulvestrant in patients with hormone receptor–positive, metastatic breast cancer, according to a gene expression analysis.

Nicholas C. Turner, MD, PhD, of Royal Marsden Hospital and Institute of Cancer Research in London, and his colleagues used a gene expression panel to detect biomarkers related to the efficacy of palbociclib plus fulvestrant in patients with endocrine-pretreated metastatic breast cancer.

“No predictive biomarkers have been identified in randomized trials of CDK4/6 inhibitors,” the researchers wrote in the Journal of Clinical Oncology.

Study participants were randomly assigned to receive either combination palbociclib and fulvestrant (n = 194) or placebo and fulvestrant (n = 108). The primary analysis was completed using data from the PALOMA-3 trial, which included 10 genes selected from a panel search of 2,534 genes.

The association between level of gene expression and efficacy of palbociclib combination therapy was evaluated by way of advanced statistical analysis.

After analysis, the efficacy of palbociclib was found to be reduced with high levels of cyclin E1 mRNA expression compared with low levels (median PFS palbociclib arm, 7.6 vs. 14.1 months; placebo arm, 4.0 vs. 4.8 months; P = .00238).

“These data suggest that CCNE1 mRNA expression may be associated with the benefit from palbociclib in early-stage breast cancer,” they wrote.

The authors acknowledged that one key limitation of the study was that the biomarkers identified may not be relevant to other CDK4/6 inhibitor combinations.

“Additional methodologic and clinical validations are warranted to elucidate the role of CCNE1 mRNA expression as a biomarker of CDK4/6 inhibitor therapy,” they concluded.

The study was supported by Pfizer. The authors reported financial interests with AbbVie, AstraZeneca, Genentech, Novartis, Pfizer, and others.

Study participants were randomly assigned to receive either combination palbociclib and fulvestrant (n = 194) or placebo and fulvestrant (n = 108). The primary analysis was completed using data from the PALOMA-3 trial, which included 10 genes selected from a panel search of 2,534 genes.

The association between level of gene expression and efficacy of palbociclib combination therapy was evaluated by way of advanced statistical analysis.

After analysis, the efficacy of palbociclib was found to be reduced with high levels of cyclin E1 mRNA expression compared with low levels (median PFS palbociclib arm, 7.6 vs. 14.1 months; placebo arm, 4.0 vs. 4.8 months; P = .00238).

“These data suggest that CCNE1 mRNA expression may be associated with the benefit from palbociclib in early-stage breast cancer,” they wrote.

The authors acknowledged that one key limitation of the study was that the biomarkers identified may not be relevant to other CDK4/6 inhibitor combinations.

“Additional methodologic and clinical validations are warranted to elucidate the role of CCNE1 mRNA expression as a biomarker of CDK4/6 inhibitor therapy,” they concluded.

The study was supported by Pfizer. The authors reported financial interests with AbbVie, AstraZeneca, Genentech, Novartis, Pfizer, and others.

Elderly people were significantly more likely to experience a fracture while walking a dog in 2017 than they were in 2004, according to data from the U.S. Consumer Product Safety Commission.

The estimated number of fractures associated with walking a leashed dog was 4,396 in 2017 among those aged 65 years and older, compared with 1,671 in 2004, which is a significant increase, Kevin Pirruccio of the University of Pennsylvania, Philadelphia, and his associates wrote in JAMA Surgery.

Over the entire study period, 2004-2017, almost 79% of all fractures occurred in women and 67% of all patients were treated in the emergency department and released. The most common injury was hip fracture (17.3%), although upper-extremity fractures were more common (52.1%) than those of the lower extremities (29.4%), trunk (10.1%), or head and neck (7.3%), the investigators reported.

“For older adults – especially those living alone and with decreased bone mineral density – the risks associated with walking leashed dogs merit consideration. Even one such injury could result in a potentially lethal hip fracture, lifelong complications, or loss of independence,” they wrote.

The retrospective, cross-sectional analysis involved the Consumer Product Safety Commission’s National Electronic Injury Surveillance System database, which includes approximately 100 hospital emergency departments. The investigators did not report any conflicts of interest.

A new safety communication from the Food and Drug Administration on the use of robotically assisted surgical devices for mastectomy and other cancer-related surgeries in women encourages physician-patient dialogue and suggests that, moving forward, data on specific oncologic outcomes – not only perioperative and short-term outcomes – are key.

The FDA is “warning patients and providers that the use of robotically assisted surgical devices for any cancer-related surgery has not been granted marketing authorization by the agency, and therefore the survival benefits to patients when compared to traditional surgery have not been established,” Terri Cornelison, MD, PhD, assistant director for the health of women in the FDA’s Center for Devices and Radiological Health, said in a statement.

The safety communication focuses on women and calls attention specifically to robotically-assisted mastectomy and hysterectomy for early cervical cancers. It says there is “limited, preliminary evidence that the use of robotically-assisted surgical devices for treatment or prevention of cancers that primarily (breast) or exclusively (cervical) affect women may be associated with diminished long-term survival.”

The FDA cited a multicenter randomized trial that found that minimally invasive radical hysterectomy in women with cervical cancer (laparoscopic and robotically assisted) was associated with a lower rate of long-term survival compared with open surgery (N Engl J Med. 2018;379:1895-1904).

The communication does not refer to any other specific studies. Regarding current evidence on robotically-assisted mastectomies, the FDA safety communication says simply that safety and effectiveness have not been established and that the agency is “aware of scientific literature and media publications describing surgeons and hospital systems that use robotically-assisted surgical devices for mastectomy.”


 

Robotically-assisted mastectomy

Walton Taylor, MD, president of the American Society of Breast Surgeons and a surgeon with Texas Health Physicians Group in Dallas, said that the FDA’s concern is valid. “I really hope that robotic surgery turns out to be good [for mastectomy]. It’s awesome technology that can be great for patients,” he said. “But we have to gather real data that shows that long-term and short-term outcomes – from a cancer standpoint – are as good as with the open procedure ... that there aren’t negative unintended consequences.”

Right now, Dr. Taylor said, robotic mastectomy “is not commonplace by any means.”

The technique for robotic nipple-sparing mastectomy (NSM) was first described by Antonio Toesca, MD, of the European Institute of Oncology in Milan (Ann Surg. 2017;266[2]:e28-e30).

In an editorial published recently in Annals of Surgical Oncology, Jesse C. Selber, MD, MPH, of the department of plastic surgery at the University of Texas MD Anderson Cancer Center in Houston, described the technique as a “natural next step in the evolution of minimally invasive breast surgery that has the potential to mitigate the challenges associated with traditional NSM” (Ann Surg Oncol. 2019;26[1]:10-11). Robotic nipple-sparing mastectomy is catching on in Europe” with very promising early results, he wrote.

At least a couple of practices promoted their performance of robotic mastectomy last year. Northwell Health, a large network of hospitals, outpatient facilities, and physicians in New York, announced in March 2018 that Neil Tanna, MD, and Alan Kadison, MD, of the divisions of plastic and reconstructive surgery and surgical oncology, respectively, had performed the first robotic nipple-sparing mastectomy and breast reconstructive surgery in the United States. Their patient carried the BRCA gene and had a preventive mastectomy at Northwell Health’s Long Island Jewish Medical Center.

In October 2018, a surgeon in Tinton Falls, N.J., Stephen Chagares, MD, announced that he had performed the first robotic nipple-sparing mastectomy with reconstruction in a patient with breast cancer at Monmouth Medical Center. His press release described a 3-cm incision “to the side of the breast, tucked neatly behind the armpit.” Both Dr. Chagares and Dr. Tanna had traveled to Milan to train with Dr. Toesca, according to the press releases.

Both of these cases – as well as a decision by Monmouth Medical Center in December 2018 to suspend the surgery pending further review – were mentioned in a letter submitted to the FDA in mid-December by Hooman Noorchashm, MD, PhD, a Philadelphia cardiothoracic surgeon-turned-patient-advocate whose wife Amy Josephine Reed, MD, PhD, died of uterine cancer in May 2017 following a laparoscopic hysterectomy performed with a power morcellator.

In his complaint, Dr. Noorchashm urged the agency to issue a warning about the “potentially dangerous/premature application” of robotic mastectomy for the treatment of breast cancer or BRCA carrier status outside the setting of randomized controlled trials with primary cancer–related outcomes metrics or an investigational device exemption from the FDA. (Receipt of the letter was acknowledged by the Allegation of Regulatory Misconduct Branch of the FDA several days later.)

In an interview, Dr. Noorchashm said he wants to see a regulatory framework that doesn’t allow 510(k) devices (devices requiring a premarket notification to the FDA) to modify an existing standard of care without having been shown to have noninferior primary outcomes. When devices are used in the diagnosis or treatment of cancerous or potentially cancerous tissue, he said, this means primary oncologic outcomes must be shown to be noninferior.

“When you have 510(k) devices able to inject themselves and affect existing standards of care without any sort of clinical trial requirement, you get the standard of care changing without any outcomes data to back it up,” he said. “That’s what happened with the power morcellator. Physicians started using it without any sort of prospective data, level 1 outcomes data, and it dramatically changed the conduct of hysterectomies.”

In its safety communication, the FDA encourages the establishment of patient registries to gather data on robotically-assisted surgical devices for all uses, including the prevention and treatment of cancer. It also says that while the agency’s evaluation of the devices has generally focused on complication rates at 30 days, the FDA “anticipates” that their use in the prevention or treatment of cancer “would be supported by specific clinical outcomes, such as local cancer recurrence, disease-free survival, or overall survival at time periods much longer than 30 days.”

The American Society of Breast Surgeons has a Nipple Sparing Mastectomy Registry that is collecting oncologic outcomes as well as aesthetic outcomes and other metrics on 2,000 patients. “In the last year or two, we’ve seen nipple-sparing mastectomy become much more commonplace,” said Dr. Taylor. Thus far, the registry does not include robotic procedures, but “if there were interest in a registry specifically for robotic nipple-sparing mastectomy, we would do it in a heartbeat.”


 

Gynecologic oncology surgery

The randomized controlled study on radical hysterectomy for cervical cancer that caught the FDA’s attention reported lower rates of disease-free survival at 4.5 years with minimally invasive surgery than with open abdominal surgery (86% versus 96.5%) and lower rates of overall survival at 3 years.

The phase 3 multicenter Laparoscopic Approach to Cervical Cancer trial recruited more than 600 women with stage IA1, IA2, or IB1 cervical cancer. Most (91.9%) had IB1 disease and either squamous-cell carcinoma, adenocarcinoma, or adenosquamous carcinoma. Differences in the outcomes remained after adjustment for age, body mass index, disease stage, lymphovascular invasion, and lymph-node involvement. The findings led to early termination of the study.

The study did not single out robotically-assisted surgery. It was a two-arm study and was “not powered to analyze laparoscopy versus robotics,” lead author Pedro T. Ramirez, MD, of the University of Texas MD Anderson Cancer Center, said in an interview. “But based on our numbers, we saw no difference [in outcomes] between the two groups.” Of the patients who underwent minimally invasive surgery, 84.4% underwent laparoscopy and 15.6% underwent robot-assisted surgery.

The study, funded by MD Anderson and Medtronic, has been criticized for potential design and conduct issues. Outside experts pointed out that the study involved extremely small numbers of patients at each of the 33 participating centers, and that cancer recurrences were clustered at 14 of these centers. It’s important to appreciate, Dr. Ramirez said in the interview, that the majority of patients were accrued in these 14 centers.

In its safety communication, the FDA noted that other researchers have reported no statistically significant difference in long-term survival when open and minimally invasive approaches to radical hysterectomy for cervical cancer have been compared.

Asked to comment on the FDA’s safety communication, Dwight D. Im, MD, who leads the National Institute of Robotic Surgery at Mercy in Baltimore, said in an e-mail that “while robotic surgery may advance into new areas, such as mastectomy and cancer prevention, more research must be done and this should be part of any conversation between gyn-surgeons who are experienced in the realm of robotic surgery, and their patients.”

Regarding the treatment of cervical cancer, “I think it is safe to say that most gynecologic oncologists now offer only open laparotomies until we have more data comparing open to minimally invasive (laparoscopic and robotic) approaches,” he said.

The FDA said in a briefing document accompanying the safety communication that it has received a “small number of medical device reports of patient injury when [robotically-assisted surgical devices] are used in cancer-related procedures.”

According to the FDA spokesperson, 5 of 32 medical device reports received between January 2016 and December 2018 describe patients who underwent hysterectomy and experienced metastases afterward. It does not appear that any of the 5 cases were a direct result of a system error or device malfunction, and the complications described in the reports are not unique to robotically-assisted surgical devices, the spokesperson said.

The safety communication “reflects the agency’s commitment to enhancing the oversight of device safety as part of our Medical Device Action Plan, as well as the agency’s ongoing commitment to advancing women’s health.”

Dr. Taylor reported that he has no current financial disclosures. Dr. Ramirez reported to the New England Journal of Medicine that he had no relevant disclosures. Dr. Im reported that he is a speaker for Intuitive Surgical, which manufacturers the da Vinci Surgical System, as well as for Conmed and Ethicon.

Ramirez, MD, of the University of Texas MD Anderson Cancer Center, said in an interview. “But based on our numbers, we saw no difference [in outcomes] between the two groups.” Of the patients who underwent minimally invasive surgery, 84.4% underwent laparoscopy and 15.6% underwent robot-assisted surgery.

The study, funded by MD Anderson and Medtronic, has been criticized for potential design and conduct issues. Outside experts pointed out that the study involved extremely small numbers of patients at each of the 33 participating centers, and that cancer recurrences were clustered at 14 of these centers. It’s important to appreciate, Dr. Ramirez said in the interview, that the majority of patients were accrued in these 14 centers.

In its safety communication, the FDA noted that other researchers have reported no statistically significant difference in long-term survival when open and minimally invasive approaches to radical hysterectomy for cervical cancer have been compared.

Asked to comment on the FDA’s safety communication, Dwight D. Im, MD, who leads the National Institute of Robotic Surgery at Mercy in Baltimore, said in an e-mail that “while robotic surgery may advance into new areas, such as mastectomy and cancer prevention, more research must be done and this should be part of any conversation between gyn-surgeons who are experienced in the realm of robotic surgery, and their patients.”

Regarding the treatment of cervical cancer, “I think it is safe to say that most gynecologic oncologists now offer only open laparotomies until we have more data comparing open to minimally invasive (laparoscopic and robotic) approaches,” he said.

The FDA said in a briefing document accompanying the safety communication that it has received a “small number of medical device reports of patient injury when [robotically-assisted surgical devices] are used in cancer-related procedures.”

According to the FDA spokesperson, 5 of 32 medical device reports received between January 2016 and December 2018 describe patients who underwent hysterectomy and experienced metastases afterward. It does not appear that any of the 5 cases were a direct result of a system error or device malfunction, and the complications described in the reports are not unique to robotically-assisted surgical devices, the spokesperson said.

The safety communication “reflects the agency’s commitment to enhancing the oversight of device safety as part of our Medical Device Action Plan, as well as the agency’s ongoing commitment to advancing women’s health.”

Dr. Taylor reported that he has no current financial disclosures. Dr. Ramirez reported to the New England Journal of Medicine that he had no relevant disclosures. Dr. Im reported that he is a speaker for Intuitive Surgical, which manufacturers the da Vinci Surgical System, as well as for Conmed and Ethicon.

DALLAS – The National Multiple Sclerosis society has awarded the 2018 Barancik Prize for Innovation in Multiple Sclerosis Research to Katerina Akassoglou, PhD.

Dr. Akassoglou laid out the course of research into the role of fibrinogen in multiple sclerosis and other neurodegenerative disorders during her talk at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis.

Dr. Akassoglou and her collaborators questioned the received wisdom about what happens when the brain’s vasculature is disrupted, she said in a video interview. “Fibrinogen was studied for several decades as only a marker of blood-brain barrier disruption. We asked the question, ‘Is it possible that it’s not only a marker, but it also plays a role in disease pathogenesis?’ ”

Over the years, said Dr. Akassoglou, she and her collaborators have developed tools “to dissect this chicken-and-egg question.” A key answer came when the researchers found that when fibrinogen leaks through the vasculature into brain tissue, it can promote inflammatory processes. “At the same time, it induced pathogenic responses in brain immune cells, causing them to be toxic to neuronal cells.”

“Using genetic models of depleting fibrinogen, or blocking its interactions with immune receptors, provided compelling data that this could be an important target for neurodegeneration and neuroinflammation,” said Dr. Akassoglou, professor of neurology at the University of California, San Francisco.

The problem came in trying to find a way to block or deplete fibrinogen inside central nervous system tissue without inactivating it throughout the circulation, since it’s essential for hemostasis.

A promising answer to this problem lies in an investigational monoclonal antibody that binds selectively to sites on fibrinogen that are activated in the brain but are not involved with fibrinogen’s usual role in the clotting cascade in the peripheral circulation, she said.

DALLAS – Rhonda Voskuhl, MD, delivered the Kenneth P. Johnson Memorial lecture at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis. In an hour-long talk, Dr. Voskuhl outlined her research approach, which she terms the “bedside to bench to bedside” strategy.
 

“My view has been that, when we start out research based on a molecule, we don’t really know for sure its clinical relevance. It’s kind of high risk, because you could go through a lot of work, for many years,” she said in a video interview. When work begins in vitro, the researcher runs the risk of proceeding from test tubes, to animal experiments, and then to people, “and then ultimately finding out that it’s not relevant,” said Dr. Voskuhl, director of the multiple sclerosis (MS) program and Jack H. Skirball Chair of Multiple Sclerosis Research at the University of California, Los Angeles.

“And so I just thought, to derisk this whole thing, I think I want to start at the end and then work backwards,” by choosing a physiologically relevant manifestation of MS, she said. “We know that there’s something there. ... All we have to do is figure it out.”

In iterative fashion, Dr. Voskuhl proceeds from the clinical observation, “which we know is true, and then go to the laboratory bench and figure it out by doing a lot of manipulation and isolation of one thing versus another.”

This process allows researchers to narrow down fruitful pathways before returning to the patient to conduct clinical trials using the one or two promising avenues discovered with bench science and animal models, she said.

“When you put this in the context of cell-specific and region-specific gene expression, to find disability-specific treatments,” Dr. Voskuhl said, this targeted approach helps address the fact that MS patients differ so much in their presentations and disease course.

“We know that, for example, the neuronal cells differ, and some of the neurotrophic cells differ from pathway to pathway; furthermore, what’s important is that oligocytes and astrocytes and dendrocytes have been shown to differ from one region of the brain and spinal cord to another. So these clearly would have different gene expression signatures, potentially posing different targets for treatment,” Dr. Voskuhl said.

The American Society of Clinical Oncology has issued a new guideline on the early detection and management of colorectal cancer in people at average risk for colorectal cancer, which was written by Gilberto Lopes, MD, of the University of Miami and his associates on an ASCO expert panel.

The panel assembled by ASCO to write the guideline consisted of medical oncology, surgical oncology, surgery, gastroenterology, health technology assessment, cancer epidemiology, pathology, radiology, radiation oncology, and patient advocacy experts. Guidelines from eight different developers were examined, and recommendations from those guidelines were adapted to form the new ASCO guideline. The guideline was published in the Journal of Global Oncology.

In people who are asymptomatic, are aged 50-75 years, have no family history of colorectal cancer, are at average risk, and are in settings with high incidences of colorectal cancer, the expert panel recommends guaiac fecal occult blood test or fecal immunochemical testing every 1-2 years, flexible sigmoidoscopy every 5 years, a combination of flexible sigmoidoscopy every 10 years and annual stool-based testing, or colonoscopy every 10 years, depending on available resources. The testing strategy for those with positive stool-based testing or flxible sigmoidoscopy is colonoscopy or a double-contrast barium enema if colonoscopy is unavailable.

For patients who have polyps, polypectomy at the time of colonoscopy is recommended, with the option of referral for surgical resection if not suitable for endoscopic resection. When symptoms (iron-deficiency anemia, bleeding abdominal pain and/or change in bowel habits) are present, a colonoscopy should be performed if available. If colonoscopy is contraindicated, a double-contrast barium enema can be performed; if endoscopy is contraindicated, CT colonography can be performed.

More information, including a data supplement with additional evidence tables, a methodology supplement with information about evidence quality and strength of recommendations, slide sets, and clinical tools and resources is available at www.asco.org/resource-stratified-guidelines, the guideline noted.

Several members of the expert panel reported conflicts of interest.

An expert panel appointed by the American Society of Clinical Oncology has issued a new guideline for the treatment and follow-up of patients with early-stage colorectal cancer.

The multidisciplinary, multinational panel identified and reviewed previous guidelines from 12 different developers to create the new ASCO guideline; of these, recommendations from six guidelines were adapted into the evidence base. All recommendations have a consensus rate of at least 75%.

For patients with basic, nonobstructing stage I-IIA colon cancer, open resection is recommended; those with enhanced disease should receive laparoscopic or minimally invasive surgery. For nonobstructing stage IIB-IIC colon cancer, recommended treatment for basic disease is open resection; emergency surgical resection is recommended in enhanced disease.

Treatment for basic, obstructing IIB-IIC disease is resection and/or diversion and is emergency surgical resection in enhanced disease. In left-sided, stage IIB-IIC disease, colonic stent placement is recommended. In high-risk, obstructing stage II disease or in T4N0/T3N0 disease with high-risk features, adjuvant chemotherapy is recommended.

In cT1N0 and cT2n0 rectal cancer, total mesorectal excision is recommended; for cT3n0, total mesorectal excision is recommended in basic and limited cases, with diversion recommended in other cases. For resectable cT3N0 rectal cancer, patients should receive base neoadjuvant chemotherapy.

For follow-up, patients should receive a combination of medical history, physical examination, carcinoembryonic antigen testing, imaging, and endoscopy, with the frequency depending on patient setting.

More information, including a data supplement with additional evidence tables, a methodology supplement with information about evidence quality and strength of recommendations, slide sets, and clinical tools and resources is available at www.asco.org/resource-stratified-guidelines, according to the guideline.
