Gestational trophoblastic tumors (GTTs) are the malignant forms of gestational trophoblastic diseases. They always follow a pregnancy, most often molar. The diagnosis of GTT is based on an abnormal course of HCG (chorionic gonadotropin hormone) and/or signs of ultrasound invasion and/or histological confirmation. We report a retrospective series of 10 cases of GTT collected at the Medical Oncology Department of the Moulay Ismail Military Hospital in Meknes over an 8-year period from January 2012 to January 2020. The analysis of our series led to the conclusion that: The average age of onsetis 42 years. 90% of our patients were pauciparic. The causal pregnancy was in 90% of the cases a molar pregnancy. The extension assessment was mainly based on the TAP CT identifying the lung as the main metastatic site in 40% of cases. 5 patients (50% of cases) underwent hysterectomy with post operative chemotherapy. 60% of our patients were classified as low risk according to the FIGO score and received methotrexate mono-chemotherapy. 4 patients were classified as high-risk and were treated with poly chemotherapy, the main protocol of which was EMA-CO. All our patients benefited from clinical and biological monitoring, before each chemotherapy session; then weekly and monthly after negativation, up to 12 months in case of good prognosis GTT, and up to 18 months in case of bad prognosis GTT. One case of MTX relapse (the case of IPTT) was reported and for which a 2nd line CMT with a favourable evolution was indicated. This study allowed us to analyze the cure rate, which was 100% for patients who were treated and had completed their monitoring.
