In The Know-October 2026

Pdf Summary
The October 2026 gynecologic oncology literature highlights advances in treatment, prevention, diagnostics, and surgical care.<br /><br />In advanced or recurrent endometrial cancer previously treated with platinum chemotherapy and immunotherapy, phase 3 results found that sacituzumab tirumotecan improved median progression-free survival (7.2 vs 3.9 months) and overall survival (19.0 vs 12.1 months) compared with physician’s-choice chemotherapy, though grade 3 or higher adverse events were more common.<br /><br />In PAOLA-1, adding maintenance olaparib to bevacizumab did not meaningfully worsen overall quality of life; among patients with HRD-positive tumors, it was associated with a longer time to quality-of-life deterioration. A separate exploratory study identified IL-6, osteopontin, and PlGF as potential outcome-related biomarkers in recurrent endometrial cancer.<br /><br />Prevention findings support opportunistic salpingectomy during indicated surgery for people at average ovarian cancer risk. Modeling suggests standalone salpingectomy may be cost-effective for those with moderately elevated risk, but not average risk. Bariatric surgery was associated with lower overall obesity-related cancer risk, including endometrial and ovarian cancers, across age groups and sexes; pancreatic cancer risk was higher, particularly in younger adults.<br /><br />A randomized trial of radical hysterectomy found fewer, mostly minor, intraoperative complications with robotic surgery, but similar postoperative complications and only small differences in early quality of life. For tubo-ovarian abscess, transvaginal drainage shortened hospitalization and improved early pain, but did not establish noninferiority to laparoscopy and required more reinterventions.<br /><br />Other reports raise clinical considerations: follow-up of O-RADS US 3 ovarian lesions at six weeks is proposed for study; pathologists showed only moderate initial agreement diagnosing STIC, with some cases reclassified as invasive cancer; and deep learning based on pathology images showed promise for predicting HRD. Cohort studies also linked lichen planus with increased site-specific oral and genital cancer risk, and childhood higher BMI trajectories with later endometrial cancer risk.
