[Double primary carcinoma of the uterine corpus and ovary]

This article presents 19 patients with double primary carcinoma of the uterine corpus and ovary diagnosed and treated at Queen Mary Hospital, University of Hong Kong in last ten years. 14 patients had typical endometrial adenocarcinoma and endometrioid carcinoma of the ovary (group A), 5 had non-endometrioid carcinoma in the uterine corpus and/or ovary (group B). There is no significant difference in survival rate in group A and B (78.6% and 80%, respectively, mean follow-up 42 months), but the total survival rate in our series is 78%, which is equal to stage I ovarian cancer. The tumor grade and positive abdominal washing were proven to be statistically significant indicators of the poor prognosis (P < 0.05). The result reveals that the prognosis of double primary carcinoma of the uterine corpus and ovary is better and it is necessary to distinguish double primary carcinoma of the uterine corpus and ovary from stage II ovarian cancer and stage III endometrial carcinoma.
