　View Summary

Objective: To evaluate the survival impact of neoadjuvant chemotherapy followed by interval debulking surgery (NACT/IDS) versus primary debulking surgery (PDS) in patients with advanced epithelial ovarian cancer of non–high-grade serous carcinoma (HGSC) histology. Methods: A retrospective analysis was conducted using the Japan Society of Obstetrics and Gynecology tumor registry (2017 to 2022). Patients with FIGO stage III–IV ovarian, fallopian tube, or primary peritoneal cancer were classified by histology (HGSC or non-HGSC), and compared initial treatment. Overall survival (OS) was analyzed using multivariate Cox proportional hazard model and propensity score matching (PSM). Results: Among 20,212 eligible cases, 14,718 (72.8 %) were HGSC and 5494 (27.2 %) were non-HGSC, primarily clear cell (2389;11.8 %) and endometrioid (1431;7.1 %) carcinomas. In HGSC patients, 7118 (48.4 %) received NACT, while in non-HGSC, 1203 (21.9 %) received NACT. Compared with HGSC, non-HGSC patients were younger, more frequently registered in eastern Japan, diagnosed at FIGO 2014 stage IIIA/IIIB, and underwent PDS and nodal evaluation (all, P < .05). In the overall cohort, non-HGSC histology was independently associated with poorer OS (adjusted-hazard ratio [HR]1.35, P < .001). Upstaging/IDS failure was higher in non-HGSC (36 %) vs HGSC (25 %, P < .001). After PSM, 5-year OS was comparable between HGSC patients who achieved IDS after NACT and those who underwent PDS (36.8 % vs 35.6 %; HR0.83, P = .12), whereas IDS failure was associated with markedly worse survival (3.9 %; HR3.12, P < .001). Conclusion: In non-HGSC, the rate of upstaging/IDS failure after NACT reached approximately 36 %; however, achieving IDS after NACT resulted in survival comparable to PDS, highlighting the need to select appropriate candidates.

　View Summary

Aim: To provide information including the trend of gynecological malignancies in Japan, we hereby present the Annual Patient Report for 2022 and the Annual Treatment Report for 2017, on the outcomes of patients who started treatment in 2017. Methods: The Japan Society of Obstetrics and Gynecology maintains an annual tumor registry, where information on gynecological malignancies from various participating institutions is gathered. The data of patients whose treatment with gynecologic malignancies was initiated in 2022 were analyzed retrospectively. Survival of the patients who started treatment with cervical, endometrial, and ovarian cancer in 2017 was analyzed by using the Kaplan–Meier, log–rank, and Wilcoxson tests. Results: Treatment was initiated in 2022 for 8039 patients with cervical cancer, 14 518 with endometrial cancer, 8524 with ovarian, tubal, and peritoneal cancer, 2360 with ovarian borderline tumors, and with the others (270 vulvar cancer, 179 vaginal cancer, 539 uterine sarcoma, 48 uterine adenosarcoma, 158 trophoblastic diseases). This clinicopathological information was summarized as the Patient Annual Report. The 5-year survival rates of the patients who initiated treatment in 2017 were as follows. For cervical cancer, the rates were 93.0%, 76.1%, 59.5%, and 28.3% for Stages I, II, III, and IV, respectively. For endometrial cancer, the rates were 94.9%, 88.8%, 72.7%, and 28.9% for Stages I, II, III, and IV, respectively. For ovarian cancer, the rates were 91.7%, 76.6%, 54.4%, and 45.2% for Stages I, II, III, and IV, respectively. Conclusion: The annual tumor report is an important survey that provides knowledge on gynecological malignancy trends in Japan.
