title: Clinicopathologic analysis of the prognostic factors in women with coexistence of endometrioid adenocarcinoma in the endometrium and ovary.
abstract: OBJECTIVE
  To compare the survival and prognostic factors of patients with dual primary ovarian and endometrial cancers (primary group), and endometrial cancers metastatic to the ovaries (metastatic group).
  
  
  METHODS
  Thirty-six patients with gross tumors confined to the pelvis and of endometrioid adenocarcinoma subtype in both the endometrium and ovary were selected from our file of 546 Japanese women with endometrial carcinoma. The patients were divided into two groups. Eleven were classified into the primary group. Twenty-five were classified into the metastatic group. Both univariate and multivariate regression analyses were carried out.
  
  
  RESULTS
  The mean age of the primary group was significantly younger than that of the metastatic group (45.2 years vs 51.2 years; P < 0.01). The cumulative 10-year survival of the primary group was significantly better than that of the metastatic group (90.9%vs 46.6%; P < 0.05). Univariate analyses showed that older age (P < 0.05) and the presence of lymphovascular space invasion (LVSI; P < 0.004) of the tumor of the uterus were significantly associated with a poor prognosis in the metastatic group. Multivariate analysis including the above variables showed no independent prognostic factor (older age, P < 0.60 and LVSI, P < 0.06).
  
  
  CONCLUSIONS
  When encountering women with coexisting endometrioid carcinoma in the endometrium and ovary with gross tumor limited to the pelvis, more attention should be paid to LVSI of the tumor of the uterus as a poor prognostic indicator.
