Prognostic impact of the subclassification of Müllerian cancer stage IV in the FIGO 2014 staging system with a focus of extra-abdominal lymph node metastases.

In this analysis of the revised FIGO system of patients reclassified as FIGO stage IVA or IVB, no new prognostic information was obtained. There is a possibility that stage IVB patients diagnosed with extra-abdominal lymph node metastasis only can be classified as an earlier stage. Further modification of the FIGO staging system may be needed to improve the prediction of patient prognosis.
