Fitty-one patients with choriocarcinoma associated with term pregnancy were treated at the John I. Brewer Trophoblastic Disease Center of Northwestern University Medical School from 1962 through 1981. An overall remission rate of 61% was achieved: 65% for 43 patients who received all of their treatment at the center and 38% for eight patients who received treatment elsewhere before referral to the center. This remission rate was significantly less (P < 0.005) than the 87% remission rate obtained in patients with choriocarcinoma after hydatidiform mole, abortion, or ectopic pregnancy combined. Three factors were determined which significantly influenced response to treatment in these patients: (1) time from delivery to treatment greater than 4 months (41% versus 80%, P < 0.0005); (2) presenting symptomatology other than abnormal uterine bleeding (40% versus 87%; P < 0.001); and (3) metastases to sites other than the lung and/or vagina (22% versus 72%, P < 0.01). There appeared to be no advantage to treating all patients with choriocarcinoma after term pregnancy with initial multiple-agent chemotherapy unless other high-risk characteristics were present.
