Overview

NCI Definition: A diverse group of pregnancy-related tumors characterized by excessive proliferation of trophoblasts. Representative examples include hydatidiform mole, gestational choriocarcinoma, and placental site trophoblastic tumor. [1]

Gestational trophoblastic tumors most frequently harbor alterations in TP53, SPEN, KMT2D, KEAP1, and SMAD4 [2].

Most Commonly Altered Genes in Gestational Trophoblastic Tumor

TP53 Mutation, KEAP1 Mutation, TP53 c.217-c.1178 Missense, TP53 Nonsense, and TP53 Missense are the most common alterations in gestational trophoblastic tumor [2].
