The prognostic significance of surgical staging for carcinoma of the endometrium.

Abstract：

:This study is based on a retrospective review of 156 patients with endometrial carcinoma from 1978 through 1984 who underwent primary surgical evaluation. All cases were retrospectively restaged using the newly adopted FIGO surgical staging. The preoperative FIGO clinical stage distribution for this study was as follows: 121 (77.6%) Stage I, 22 (14.1%) Stage II, 5 (3.2%) Stage III, 2 (1.3%) Stage IV, and 6 (3.8%) unstaged patients. Most patients had TAH-BSO with a collection of peritoneal washings and retroperitoneal lymph node sampling. Surgical staging revealed 122 (78.2%) Stage I, 9 (5.8%) Stage II, 12 (7.7%) Stage III, and 13 (8.3%) Stage IV patients. Surgery upstaged 12.4% of clinical Stage I. In clinical stage II, 59.0% were downstaged while 27.3% were upstaged. For clinical Stage III, 60.6% were upstaged, but no downstaging occurred. No change in stage occurred for clinical Stage IV patients. Ninety-seven surgically staged patients received no adjuvant therapy. The remaining 59 patients had adjunctive treatment which consisted of radiotherapy (59.3%), hormonal therapy (25.4%), chemotherapy (5.1%), or combined modality treatment (10.2%). All patients were followed until death or a minimum of 5 years (60-139 months; median, 82 months) with the exception of 13 patients who were lost to follow-up (2-58 months; median, 34 months). Five-year survival by clinical staging was as follows: 86.2% for Stage I, 85.9% for Stage II, and 0% for Stage III and IV. Five-year survival by surgical staging was 90.6% for Stage I, 85.7% for Stage II, 58.3% for Stage III, and 0% for Stage IV. The 13 patients who were lost to follow-up were censored in all survival analyses at the time of last contact. Stepwise regression analysis using a parametric proportional hazards model identified surgical stage as the most significant prognostic factor (P = 0.02). Univariate analysis showed that patients with surgical Stage IC had significantly worse prognosis (75.0%, 5 years) than those in surgical Stage IA (93.8% 5 YS) or IB (95.4% 5 years). In summary, this study demonstrates that surgical staging as recommended by FIGO is indicated to accurately determine the initial extent of disease in endometrial carcinoma. In addition, surgical staging is the strongest predictor of survival. Deep myometrial invasion appears to be a significant independent prognostic factor within surgical Stage I. The role of adjunctive radiotherapy in Stage I disease awaits the results from an ongoing multi-institutional, prospectively randomized trial.
