OBJECTIVE: The objective of this study was the assessment of prognostic factors in stage IIIA endometrial cancer. METHODS: Between 1984 and 1993, 51 patients with stage IIIA endometrial cancer received definitive treatment at our institution. Thirty-seven patients had positive peritoneal cytologic findings only (stage IIIA1), and 14 had adnexal or uterine serosal involvement (USI) (stage IIIA2). Median follow-up of surviving patients was 82.5 months. RESULTS: The 5-year disease-related survival (DRS) and recurrence-free survival (RFS) were 88 and 73%, respectively. RFS was 79% in patients with stage IIIA1 disease, compared with 57% in patients with stage IIIA2 disease (P = 0.04). However, DRS did not significantly differ between stages IIIA1 and IIIA2. In the 37 patients with stage IIIA1 tumors, histologic grade 3, nonendometrioid histologic subtype, and lymphovascular invasion (LVI) significantly predicted a poor prognosis, with extraabdominal sites of failure (P < 0.05). Of the 22 patients who had stage IIIA1 disease with endometrioid histologic subtype and without LVI, none had recurrence [17 had whole abdominal irradiation (WAR) or intraperitoneal injection of (32)P, 2 had pelvic external radiotherapy (PRT)]. By contrast, of the 15 patients with either nonendometrioid histologic subtype or LVI, 9 (60%) had recurrence and 7 (47%) died of disease (12 had WAR or (32)P). An extraabdominal component was present in 7 of the 9 recurrences observed in this subgroup. Among the 14 patients with stage IIIA2 tumors (6 had WAR, 6 had PRT), those with USI had a 5-year DRS of 83% and a rate of extraabdominal failure of 83%, compared with 100 and 12.5% in patients without USI (P < 0.05). CONCLUSION: Patients with stage IIIA endometrial cancer who have endometrioid tumors, no LVI, and positive peritoneal cytologic findings as the only sign of extrauterine disease have an excellent prognosis. Nonendometrioid histologic subtype, LVI, and USI are strong predictors of distant failures and poor prognosis. Patients with either of these histologic factors should be considered candidates for systemic adjuvant therapy.

Abstract

OBJECTIVE: The objective of this study was the assessment of prognostic factors in stage IIIA endometrial cancer. METHODS: Between 1984 and 1993, 51 patients with stage IIIA endometrial cancer received definitive treatment at our institution. Thirty-seven patients had positive peritoneal cytologic findings only (stage IIIA1), and 14 had adnexal or uterine serosal involvement (USI) (stage IIIA2). Median follow-up of surviving patients was 82.5 months. RESULTS: The 5-year disease-related survival (DRS) and recurrence-free survival (RFS) were 88 and 73%, respectively. RFS was 79% in patients with stage IIIA1 disease, compared with 57% in patients with stage IIIA2 disease (P = 0.04). However, DRS did not significantly differ between stages IIIA1 and IIIA2. In the 37 patients with stage IIIA1 tumors, histologic grade 3, nonendometrioid histologic subtype, and lymphovascular invasion (LVI) significantly predicted a poor prognosis, with extraabdominal sites of failure (P < 0.05). Of the 22 patients who had stage IIIA1 disease with endometrioid histologic subtype and without LVI, none had recurrence [17 had whole abdominal irradiation (WAR) or intraperitoneal injection of (32)P, 2 had pelvic external radiotherapy (PRT)]. By contrast, of the 15 patients with either nonendometrioid histologic subtype or LVI, 9 (60%) had recurrence and 7 (47%) died of disease (12 had WAR or (32)P). An extraabdominal component was present in 7 of the 9 recurrences observed in this subgroup. Among the 14 patients with stage IIIA2 tumors (6 had WAR, 6 had PRT), those with USI had a 5-year DRS of 83% and a rate of extraabdominal failure of 83%, compared with 100 and 12.5% in patients without USI (P < 0.05). CONCLUSION: Patients with stage IIIA endometrial cancer who have endometrioid tumors, no LVI, and positive peritoneal cytologic findings as the only sign of extrauterine disease have an excellent prognosis. Nonendometrioid histologic subtype, LVI, and USI are strong predictors of distant failures and poor prognosis. Patients with either of these histologic factors should be considered candidates for systemic adjuvant therapy.
