Objective: To study the characteristics and clinical features of uterine neoplasms developed after radiation therapy for cervical carcinoma. Methods: Clinical data of 47 cases of uterine neoplasms occurred following radiation therapy for cervical carcinoma were retrospectively reviewed. Results: The median age at uterine neoplasms diagnosis was 62 years (range: 38-77 years), and the median latency period from initial therapy to development of uterine neoplasms was 14 years (range: 5-35 years). Thirty of 47 cases were endometrial carcinoma, of which 3 were uterine papillary serous carcinoma (UPSC). Seventeen of 47 patients were uterine sarcoma, all of those were carcinosarcoma. The distribution by stage, grade, and histology of 30 cases of endometrial carcinoma was as follows: stage Ⅰb, 1 case; stage Ⅰc, 2 cases; stage Ⅱ, 6; stage Ⅲa, 4; stage Ⅲb, 2; stage Ⅲc, 11; stage Ⅳ, 4 cases; grade 1, two cases; grade 2, nine; grade 3 (include 3 UPSC patients), seventeen; unknown grade, two; endometriod, 27; UPSC, 3 cases; 7 of 30 cases of endometrial carcinoma had recurrences (23.3%), at median time to recurrence was 24 months, and their median survival time was 26 months. The overall 3- and 5-year survival rates were 60% and 38%, respectively. Of the 17 cases of uterine sarcoma, the median survival was 10 months, 6 patients occurred recurrence (35.9%), at a median time to recurrence was 9 months, and their median survival was 6 months. The overall 3- and 5-year survival rates were 12% and 0, respectively. Conclusion: The main uterine neoplasms development after radiation therapy for cervical carcinoma is endometrial carcinomas, of which there is a preponderance of high-risk histological subtypes and a poor prognosis. Most of the uterine sarcomas occurred following radiation therapy for cervical carcinoma are carcinosarcomas and the prognosis is very poor. 展开更多
