Researchers are evaluating two surgical procedures, bilateral salpingectomy and bilateral salpingo-oophorectomy, to see how well they reduce the risk of ovarian cancer in women who have BRCA1 gene mutations. The study aims to determine if removing just the fallopian tubes (bilateral salpingectomy) is almost as effective as removing both the fallopian tubes and ovaries (bilateral salpingo-oophorectomy) in lowering ovarian cancer risk. This trial also assesses symptoms related to estrogen loss, quality of life, sexual function, cancer-related distress, decision-making about surgery, and treatment side effects in these patients. Participants choose between two groups: one group undergoes bilateral salpingectomy and may have their ovaries removed later, while the other group undergoes bilateral salpingo-oophorectomy. Both groups receive pelvic or transvaginal ultrasounds or pelvic MRI scans during screening, and blood samples are collected throughout the trial. Ancillary studies include quality-of-life assessments and questionnaires. The study also collects tissue and blood samples for future research. After surgery, participants have follow-up visits at 10 to 60 days, then at 6, 12, and 24 months, and annually for up to 20 years. Researchers monitor the time until any high-grade serous carcinomas develop, specifically ovarian, primary peritoneal, or fallopian tube cancers. They also track menopausal symptoms, sexual function, quality of life, cancer distress, medical decisions about surgery, and any adverse events during this long-term follow-up.

Researchers are evaluating whether adding pembrolizumab, a type of immunotherapy, to usual chemotherapy improves outcomes in patients with stage IIA, IIB, IIIA, or IIIB non-small cell lung cancer that has been removed by surgery. Pembrolizumab may help the immune system attack cancer cells and prevent tumor growth. Chemotherapy drugs like cisplatin, pemetrexed, carboplatin, gemcitabine hydrochloride, and paclitaxel work by stopping tumor cells from growing and spreading. This phase III trial compares disease-free survival between different treatment approaches involving pembrolizumab and chemotherapy. Participants are randomly assigned to one of two treatment groups. In Arm B, patients receive four cycles of chemotherapy followed by pembrolizumab given intravenously every 21 days for up to 17 cycles or every 6 weeks for 16 cycles. In Arm C, patients receive chemotherapy combined with pembrolizumab during the initial four cycles, followed by pembrolizumab alone for up to 13 cycles every 21 days or 12 cycles every 6 weeks. Chemotherapy regimens include various platinum doublets chosen by the treating physician. Arm A was closed as of February 2022. Patients may also undergo tests such as echocardiograms, MRIs, CT scans, and blood sample collections during the trial. Throughout the study, participants are monitored with regular assessments including imaging and blood tests. Follow-up visits occur 6 weeks after treatment, then every 3 months for 2 years, every 6 months for years 2-4, and annually up to 10 years after randomization. Researchers measure disease-free survival, overall survival, adverse events, drug discontinuation rates, and patient quality of life using questionnaires. The study also explores outcomes based on tumor markers like PD-L1 expression and tumor mutational burden.
