Carcinoma of the endometrium: stage I.

During the 10-year period ending December, 1972, 577 patients with Stage I endometrial cancer received their primary treatment at the Mayo Clinic. The average age of the group was 60.8 years. The higher-grade lesions were found in older individuals. The data did not show that high grade was related to age at menopause. The initial therapy was total abdominal hysterectomy and bilateral salpingo-oophorectomy. The absolute survival at 5 years was 92.7% for Stage IAG1, 86.5% for IAG2, 68.2% for IAG3, 89.6% for IBG1, 76.4% for IBG2, and 62.9% for IBG3.
