Abstract
BACKGROUND
Uterine papillary serous carcinoma (UPSC) is a histologic subtype of endometrial adenocarcinoma that is characterized by its papillary architecture, poor differentiation, and advanced stage at initial presentation. It behaves more aggressively than the more common endometrioid adenocarcinoma of the endometrium.
METHODS
The history, treatment and follow-up of 18 women with UPSC were evaluated.
RESULTS
All women underwent total hysterectomy and bilateral salpingoophorectomy. Positive lymph nodes were found in 6 of 14 patients who underwent pelvic lymphadenectomy. Twelve of 18 women with UPSC had FIGO Stage III and IV tumors in contrast to 30 of 236 patients with endometrioid adenocarcinoma (P < 000.1). Subsequent treatment of these women was: radiotherapy, three women; chemotherapy, four, both radiotherapy and chemotherapy, eight. Chemotherapy consisted of cisplatin/carboplatin plus cyclophosphamide. None of the patients with Stage I or II UPSC died of tumor during a mean follow-up of 31.6 months (range, 12-68 months). Of the women with Stage III and IV disease, 4 of 12 are alive with no evidence of disease after a mean follow-up of 22.5 months (range, 8-45 months). Eight of 12 women who received chemotherapy are alive with no evidence of disease, 4 of whom had Stage III or IV disease. One of six women who did not receive chemotherapy is alive, three died of tumor, and two of intercurrent disease.
CONCLUSION
These results would justify further study of the possible role of platinum-based chemotherapy in patients with uterine papillary serous carcinoma.
