The treatment of uterine papillary serous carcinoma (UPSC): are we doing the right thing?

Tay EH, Ward BG. The treatment of uterine papillary serous carcinoma (UPSC): are we doing the right thing? In an earlier study(1) of 21 patients with uterine papillary serous carcinoma (UPSC), Ward et al. found a poor 3-year survival, even for patients with surgically documented localized disease, and a high rate of recurrence outside the field of treatment. Eight years later, we performed a retrospective study on 67 patients who were treated initially by surgery, which included the 21 patients previously reported, to evaluate any changes in the management approach since 1990 and its impact on the survival of such patients. The clinical characteristics of patients treated before and after 1990 were similar. However, after 1990, more patients had omentectomy and complete surgical staging (42% vs. 17%); chemotherapy was more widely used (63% vs. 33%); all chemotherapies were platinum-based regimens and less radiotherapy was administered (47% vs. 83%). The overall 3-year survival was 43% and 5-year survival was 35%, with a median survival period of 31 months. There was no significant difference in the survival outcome between patients managed before and after 1990, after adjusting for stage and spread of disease. Based on the results of this retrospective study, it appears that the current treatment strategy has not resulted in an improvement in the survival of patients with UPSC.
