Mucinous endometrial cancer: Clinical study of the eleven cases

OBJECTIVE: In this study, we analyzed surgico-pathologic factors of mucinous type endometrial carcinoma and examined its frequency of recurrence. METHODS: In this study, eleven cases, definitely diagnosed as pure mucinous type endometrium carcinoma between January 1993 and May 2013, were reviewed. RESULTS: Of 1640 women with endometrium carcinoma, 11 (0.67%) of them had a mucinous cell type. Mean age of the study group was 55 years. According to the FIGO 2009, 10 (90.9%) cases were evaluated as stage I and 1 (9.1%) as stage IIIC1. The presence of lymph node metastasis was noticed in only one (12.5%) of eight patients who underwent lymphadenectomy. In this case, metastasis was detected in the pelvic lymph node. Four patients underwent adjuvant therapy as pelvic radiotherapy. Median follow-up time was 50 months (range, 5–84). Recurrence was observed in one (9.1%) patient with stage IIIC1 endometrial cancer in 30 months after primary surgery. The site of recurrence was only in the upper abdominal region. CONCLUSION: Based on our study, mucinous endometrial carcinoma has good prognostic factors, and long term survival can be achieved surgically alone in patients with stage I.
