Description

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 groupdd in old stages I, II, III and IV were 67, 86, 8 and l0, whereas those for new criteria 94, 25, 35 and l0, respectively. In 7 cades new staging was not possible because of preoptrative 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 classitied. Those of old stageIIwere 39(45.2%),21(24.55%),25(29.1%) and l(1.2%)and old stage III were l(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 comr)arison 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.
