Annual Report of the Committee on Gynecologic Oncology, Japan Society of Obstetrics and Gynecology: Patient Annual Report for 2013 and Treatment Annual Report for 2008.

The Japan Society of Obstetrics and Gynecology collects and analyzes annual data on gynecologic cancers from member institutions. We present the Patient Annual Report for 2013 and the Treatment Annual Report for 2008. Data on 7280 patients with cervical cancer, 8952 with endometrial cancer, 5792 with ovarian cancer and 1903 with ovarian borderline tumor for whom treatment was initiated in 2013 were summarized in the Patient Annual Report. Stage I accounted for 56.7%, stage II for 23.4%, stage III for 9.8% and stage IV for 10.2% of all patients with cervical cancer. Stage I accounted for 71.7%, stage II for 6.5%, stage III for 14.5% and stage IV for 7.3% of all patients with endometrial cancer. Stage I accounted for 42.2%, stage II for 9.8%, stage III for 28.2% and stage IV for 8.3% of all patients with ovarian cancer. Data on the prognosis of 3658 patients with cervical cancer, 4159 with endometrial cancer and 2866 with ovarian cancer for whom treatment was initiated in 2008 were analyzed in the Treatment Annual Report. Survival was analyzed by using the Kaplan-Meier method, the log-rank test and the Wilcoxon test. The 5-year overall survival rates for patients with cervical cancer were 93.0% for stage I, 73.1% for stage II, 55.2% for stage III and 24.2% for stage IV. The equivalent rates for patients with endometrial cancer were 94.5%, 90.3%, 74.2% and 24.0%, respectively; and those for patients with ovarian cancer (surface epithelial-stromal tumors) were 90.5%, 73.5%, 48.1% and 29.4%, respectively.
