Carcinoma of the cervix: the staging anomaly.
An analysis of 3625 carcinomas of the cervix treated in Birmingham between 1960 and 1974 showed FIGO staging to be anomalous. State 2B and 3B each contain two subgroups with differing prognosis, depending on whether one or both parametria are involved. Unilateral Stage 2B disease has a prognosis identical with Stage 2A. Bilateral Stage 2B, Stage 3A and unilateral Stage 3B disease have identical survival figures. Stages 1A, 1B and 4 and bilateral Stage 3B disease have unique survival characteristics. A system of staging combining FIGO clinical stages with prognosis facilitates interpretation of treatment results, survival figures and comparisons of series.
