Abstract Objective The mainstay of treatment for uterine endometrial cancer is surgery, and recurrent-risk cases require multidisciplinary treatment, including surgery, chemotherapy and radiation therapy. Methods The standard surgery for uterine endometrial cancer is hysterectomy and bilateral salpingooophorectomy, with additional retroperitoneal lymph node dissection and omentectomy, depending on the case. The appropriate treatment is determined based on the risk classification, such as the depth of invasion into the myometrium, diagnosis of histological type and grade, and risk assessment of lymph node metastasis. Results Recently, minimally invasive surgery has been widely used not only in low-risk patients but also in intermediate- and high-risk patients. In low-risk patients, the possibility of ovarian preservation is discussed from a healthcare perspective for young women. Determining the need for retroperitoneal lymph node dissection based on sentinel lymph node evaluation may contribute in minimizing the incidence of post-operative lymphedema while ensuring accurate diagnosis of lymph node metastasis. Recently, many studies using sentinel lymph nodes have been reported for patients with uterine endometrial cancer, and the feasibility of sentinel lymph node mapping surgery has been proven. Unfortunately, sentinel lymph node biopsy and sentinel lymph node mapping surgery have not been widely adopted in surgery for uterine cancer in Japan. In addition, the search for biomarkers, such as RNA sequencing using The Cancer Genome Atlas, metabolic profile and lipidomic profile for early detection and prognostic evaluation, has been actively pursued. Conclusions Gynecologic oncologists expect to be able to provide uterine endometrial cancer patients with appropriate treatment that preserves their quality of life without compromising oncologic outcomes in the near future.

Abstract Background Superior sulcus tumours (SSTs) are relatively uncommon and one of the most intractable lung cancers among non-small cell lung cancer (NSCLC). We planned a multicenter, single-arm confirmatory trial of new multidisciplinary treatment using immune-checkpoint inhibitor. The aim is to evaluate the safety and efficacy of new multidisciplinary treatment with perioperative durvalumab after chemoradiotherapy (CRT). Methods The primary endpoint is 3-year overall survival. Patients receive induction CRT with sequential two courses of durvalumab, followed by surgical resection for resectable SST. The regimen for CRT is two courses of cisplatin and S-1, and concurrent radiotherapy (66 Gy/33 Fr). After surgery, 22 courses of post-operative durvalumab therapy are administered. For unresectable SST, an additional 22 courses of durvalumab are administered after induction durvalumab. Results In two cases as a safety cohort, the safety of intervention treatment up to 30 days after surgery was examined, and there were no special safety signals. Patient enrollment has now resumed in the main cohort. Conclusions The results of this study may contribute to the establishment of a new standard of care for SST, which is an intractable NSCLC.
