Seventy-eight patients with endometrial carcinoma treated between 1984 and 1911 were reclassified according to FIGO stage classification, and prognose were reviewed. Fifty patients initially classed in clinical stage I were re-classified as 42 with FIGO stage I, 2 stage II, 5 stage III, and 1 stage IV. Nineteen patients with clinical stage II were re-classified as 14 with FIGO stage II and 5 stage III. Six patients with clinical stage III were re-classified as 1 with FIGO stage I, 2 with stage III and 3 with stage IV. Recurrence was observed in 1 of the 43 (2.3 %) patients in FIGO stage I, 3 of the 16 (18. 8 %) in stage II, 3 of the 12 (25 %) in stage III, and 7 of the 7 (100 %) in stage IV (p <0.01). Recurrence rates in FIGO stage I and stage III patients were lower compared with those of the respective clinical stages, and the surgical re-staging revealed that most recurrent patients were in more advanced stage than diagnosed preoperatively. Consequently, FIGO stage classification (1988) is considered to be useful for determining prognosis. [Adv Obstet Gynecol 46 (4) : 395-400, 1994 (H6. 7)]
