Relative Effects of Age, Race, and Stage on Mortality in Gestational Choriocarcinoma

Objective Gestational choriocarcinoma is a malignant form of gestational trophoblastic disease that usually arises after a molar pregnancy, but may follow any antecedent pregnancy. Investigations in this rare cancer are limited. We evaluated the prognostic effects of age, race, and stage in choriocarcinomas diagnosed for 4 decades. Methods Patients diagnosed as having gestational choriocarcinoma between 1973 and 2014 from the Surveillance, Epidemiology, and End Results program were eligible. Relationships with overall survival and cancer-specific survival were evaluated using log-rank testing and Cox modeling. Multivariate analyses included adjustments for age, race, and stage. Results There were 947 patients with choriocarcinoma including 403 non-Hispanic white (NHW) patients, 473 with distant stage, and 142 who died. Median age at diagnosis was 25 years for non-Hispanic black (NHB) patients and 35 years for Asian/Pacific Islanders (API) compared with 29 years for NHW patients (P = 0.0001). Five-year overall survival varied between 82% and 92% when diagnosed at the age of at least 40 years compared with less than 20 years (P
