BACKGROUND Gestational choriocarcinoma (GC) is an uncommon neoplasia that occurs in women who may not have completed a procreation plan. The aim of this study was to evaluate oncological and obstetrical outcomes in young patients with GC after fertility-sparing treatment. MATERIAL AND METHODS The eligibility criteria for the study were histopathological diagnosis of GC, age ≤40 years, and treatment with systemic chemotherapy. Patients who underwent upfront hysterectomy were excluded. The response to treatment was assessed according to beta-human chorionic gonadotropin (beta-hCG) serum measurement. Complete response and progression were considered if the beta-hCG dropped to a normal range and increased (or reached a plateau), respectively. The birth rate was calculated as the number of women who gave birth after treatment divided by the total number of patients. RESULTS A total of 18 patients fulfilled the study's eligibility criteria. A complete response and progression to first-line chemotherapy were found in 13 (72.22%) and 5 (27.78%) patients, respectively. Salvage treatment was administered to patients with progression. Overall, 16 (88.88%) patients achieved complete response after treatment and 2 (11.12%) died. GC relapse was diagnosed in 1 patient 62 months after treatment. The birth rate was 22.22%, and a total of 6 children were born. All pregnancies ended in term delivery. No congenital abnormalities were detected in the newborns. CONCLUSIONS GC is a life-threatening form of gestational trophoblastic neoplasia, mainly due to its rapid course and resistance to chemotherapy. Most patients with GC will not be able to bear children after treatment.
