[Clinical studies on endometrial cancer]

One hundred and fifty-two cases with endometrial carcinoma were treated in our clinic between 1973 and 1985. The average age was 55.89 years, and the age range was from 29 to 76 years. Thirty-six cases (23.7%) were nulligravidas and 42 cases (27.6%) were nulliparas. One hundred and ten cases (72.4%) were postmenopausal and the average age at menopause was 49.1 years. The most frequent chief complaint was atypical genital bleeding which was noted in 128 cases (84.2%). The result of a cytologic examination of the uterine cervix was positive in 50.7% and suspicious in 16.9% but results for the endometrium were positive in 63% and suspicious in 21.9%. The cases in this study were classified into 88 cases (57.9%) of T1a, 36 cases (23.7%) of T1b, 12 cases (7.9%) of T2, 3 cases (2.0%) of T3 and 1 case (0.7%) of T4. As to the postoperative diagnosis, there were classified into 86 cases (56.6%) of pT1a, 30 cases (19.7%) of pT1b, 19 cases (12.5%) of pT2, 10 cases (6.6%) of pT3 and 5 cases (3.3%) of pT4. Histopathologically almost all 140 cases (91.41%) were of adenocarcinoma and classified into 88 cases (57.9%) of G1, 39 cases (25.7%) of G2 and 13 cases (8.6%) of G3. The cumulative survival rates after Kaplan-Meier were 95% in pT1a cases, 75.6% in pT1b cases, 67.3% in pT2 cases, 42.2% in pT3 cases and 0% in pT4 cases.
