Gestational Trophoblastic Tumors

  • American Joint Committee on Cancer

Summary of Changes

Gestational trophoblastic tumors are effectively treated with chemotherapy even when widely metastatic so that traditional anatomic staging parameters do not adequately provide different prognostic categories. For this reason, although the anatomic categories are preserved, a scoring system of other non-anatomic risk factors has been added. This risk factor score provides the basis for substaging patients into A (low risk, score of 7 or less) or B (high risk, score of 8 or greater).

The “Risk Factors” portion of the stage grouping has been revised to reflect the new scoring system.
