according to results of the GOG-278 trial.
In fact, patients’ quality of life was improved after surgery in both groups, and their concerns about cancer recurrence decreased, especially for those undergoing simple hysterectomy, said Allan Covens, MD, in his late-breaking abstract presentation at the Society of Gynecologic Oncology (SGO)’s Annual Meeting on Women’s Cancer.
“Cone biopsy patients reported less concerns about reproductive fertility after surgery and over time compared to preop assessments,” he added.
Due to screening in developed countries, a large proportion of cervical cancers are discovered at an early stage. Treatment of these cancers with radical surgery is associated with high cure rates but significant adverse effects on quality of life, said Dr. Covens, who is with the University of Toronto, Toronto, Ontario, Canada.
He and his colleagues wanted to see if non-radical surgery could be safely used instead. “Multiple case series have indicated that non-radical surgery is associated with less morbidity and improved quality of life,” he explained. “If this can be proven in a prospective evaluation, it will change future practice.”
GOG-278 was a prospective cohort study of women with stage IA1 (lymph-vascular space invasion+) and IA2-IB1 (≤ 2 cm) carcinoma of the cervix who underwent non-radical surgery (simple hysterectomy or fertility-preserving cone biopsy) and pelvic lymphadenectomy. Criteria included ≤ 10 mm stromal invasion and negative margins on the final cone biopsy.
The primary objectives were to assess changes in functional outcomes of quality of life (bladder/bowel function, sexual function, cancer worry, and reproductive concerns), using validated instruments. Findings were based on 55 patients who underwent cone biopsy and 113 who underwent simple hysterectomy.
Both simple hysterectomy and cone biopsy were associated with “small” declines in sexual function and bladder/bowel function at 4-6 weeks after surgery, but function “quickly” recovered to baseline by 6 months, Dr. Covens reported.
Twelve patients reported a diagnosis of lymphedema, with a Gynecologic Cancer Lymphedema Questionnaire score change of 4 or higher on at least two consecutive evaluations from baseline. This occurred in six cone biopsy and six simple hysterectomy patients.
In a separate presentation, Dr. Covens reported secondary oncologic outcomes from GOG-278, which suggest that non-radical surgery for early-stage cervical cancer is safe, with low perioperative morbidity, although longer follow-up is needed.
He also reported 16 pregnancies in 15 patients who had undergone cone biopsies; 12 of these were successful, and there were four early pregnancy losses.
‘Impressive’ Data
Study discussant Kristin Bixel, MD, with The Ohio State University, Columbus, Ohio, said the data are “impressive” and clearly show that non-radical surgery has “minimal impact on bladder/bowel function, with no long-term differences from baseline.”
She added that the incidence of lymphedema was “honestly significantly lower than what I typically counsel patients about” and wondered if the percentage of patients with lymphedema would increase over time.
Dr. Bixel particularly noted the decrease in cancer worry scores after surgery, as sometimes patients who have less radical procedures fear that this comes with an increased risk for recurrence.
The “growing body of data suggests that less radical surgery is safe and effective for early-stage low-risk cervical cancer and highlights the potential reproductive success,” she concluded.
Funding for the study was provided by grants from NRG Oncology. Dr. Covens had no disclosures. Dr. Bixel has received research funding from the Intuitive Foundation.
