title: [Comparison between FIGO old and new staging criteria of endometrial carcinoma].
abstract: FIGO proposed new criteria for corpus cancer staging in 1988. One hundred and seventy-one cases of endometrial cancer were classified by these new staging criteria, and differences between grouping and survival rates for the new and old criteria were compared. 1) The number of cases grouped in old stages I, II, III and IV were 67, 86, 8 and 10, whereas those for new criteria 94, 25, 35 and 10, respectively. In 7 cases new staging was not possible because of preoperative radiation therapy and inoperability. 2) Cases of old stage I were reclassified as new stage I 54(80.5%), stage II 2(3.0%) and stage III 8(12.0%), and 3 cases were not classified. Those of old stage II were 39(45.2%), 21(24.55%), 25(29.1%) and 1(1.2%) and old stage III were 1(12.5%), 2(25.0%), 2(25.0%) and 3(37.5%), respectively. 3) Survival rates for the cases with both stage I and II cancer were very good without any apparent difference between them. Those for new stage III were very poor in comparison with old stage III. 4) In cases of stage I according to the new criteria, the depth of myometrial invasion correlated well with the survival rate. The prognosis of G3 cases with myometrial invasion over 1/2 was the poorest. 5) Survival rates among subclassifications of stages II and III were not significantly different from each other.
