The new International Federation of Gynecology and Obstetrics surgical staging and survival rates in early endometrial carcinoma

Abstract

The medical records of patients with clinical Stage I endometrial adenocarcinoma who were treated at the Maimonides Medical Center between October 1979 and October 1987 were reviewed. There was sufficient surgical‐pathologic information to allow a reclassification based on the new International Federation of Gynecology and Obstetrics (FIGO) surgical staging in 93 patients. These are the subjects of analysis. Twenty‐one patients (23%) were found surgically to have more than Stage I disease. The 5‐year survival rate for the whole group (N = 93) was 90%. However, it was significantly better for patients with surgical Stage I disease (98%) than for patients with surgical Stage III disease (60%) (P < 0.001). There was no significant statistical difference in survival among patients with different substages within surgical Stage I (i.e., IA, 100%; IB, 100%; and IC, 88%), whereas the distribution of adjuvant therapy among these substages was not statistically different (P = 0.17). Thus, survival was not significantly affected by depth of myometrial invasion in patients who had negative peritoneal washing and no involvement of lymph nodes or the peritoneal cavity.
