An intensive after-care programme for early detection of recurrence was applied to 340 patients with endometrial carcinoma. This approach proved to be effective by comparison with a control group, since 26 cases of recurrence (7.6 per cent), largely without symptoms, were identified sooner after primary therapy. While only some of the author's efforts for early recurrence detection were translatable into recurrence therapy, they feel that they should continue their after-care programme within justifiable limits. More information on therapeutic results regarding recurrence of endometrial carcinoma is expected to become available in the forthcoming years. Programme effectiveness must be judged by survival result rather than by expenses.
