title: Prognostic characteristics of surgical stage I endometrial adenocarcinoma.
abstract: OBJECTIVE
  To evaluate and correlate the expression of pathologic characteristics, flow cytometric DNA content analysis, and estrogen and progesterone receptor levels with survival in patients with surgical Stage I endometrial carcinoma.
  
  
  METHODS
  Hospital tumor registry records were surveyed, and this identified 232 patients diagnosed with endometrial adenocarcinoma between July 1, 1989, and December 30, 1993. DNA content analysis was performed on either paraffin-embedded or fresh tissue samples. Survival was calculated from the date of diagnosis by the Kaplan-Meier method. Postoperative irradiation (whole pelvis external beam therapy and low dose rate vaginal cuff brachytherapy) was delivered to patients felt to be at high risk for failure.
  
  
  RESULTS
  One hundred seventy-one patients had Stage I tumors and were available for analysis. Patients with Stage 1C tumors had a statistically significant lower survival rate compared to patients with Stages IA or IB (p = 0.03 and p < 0.01, respectively). Patients with DNA content diploid tumors had a slightly increased (but nonsignificantly so) survival compared to patients with non-DNA content diploid tumors (p = 0.12). Logistic regression analysis failed to identify an independent prognostic factor that could predict for disease specific survival in patients with Stage I cancers.
  
  
  CONCLUSIONS
  Logistic regression analysis did not identify a single independent prognostic factor in patients with Stage I tumors. Pathologic characteristics reported to predict survival advantage correlated with pathologic stage. Additional translational research is needed to identify molecular characteristics of tumors that may indicate more aggressive treatment for patients at high risk for recurrence.
