Stage II carcinoma of the endometrium. An analysis of treatment.

An analysis of 41 patients with histologically documented Stage II adenocarcinoma of the endometrium treated between 1969 and 1974 is presented. The 3-year survival for all patients was 46%. Patients treated with radiation therapy alone (tandem, ovoids, and external radiation therapy) had 29% survival while patients treated with radiation therapy and surgery had a 71% survival. For all patients, survival by grade was 80% (Grade I), 36% (Grade II), and 20% (Grade III). Among those patients with recurrent disease, 40% of cases were in the pelvis while 20% were isolated distal recurrences. Patients with stromal invasion of the cervix had a 30% survival while patients without stromal invasion had a 67% survival. An analysis of these data, along with a review of the literature, reveals that 1) hysterectomy plays a critical role in survival, 2) invasion of the cervical stroma would appear to be a requisite criteria for the establishment of Stage II disease, and 3) aggressive radiation therapy with uterine packings (Heyman capsules) should be attempted in those patients who are not surgical candidates.
