Gestational Trophoblastic Neoplasia: Experience from a Tertiary Care Center of India

Abstract

Aims: Gestational trophoblastic neoplasia (GTN) comprise a spectrum of interrelated conditions originating from the placenta. With sensitive assays for human chorionic gonadotropin (β-hCG) and current approaches to chemotherapy, most women with GTN can be cured with preservation of reproductive potential. The purpose of this analysis was to address the outcome of GTN in patients from a tertiary care center of India.

Materials and methods: We undertook a retrospective and prospective review of GTN cases treated at our center over a period of 7 years from 2008 to 2014. Patients of GTN were assigned to low-risk or high-risk categories as per the FIGO scoring system. The low-risk group was treated with combination of actinomycin-D and methotrexate and the high-risk group received the Etoposide, Methotrexate, Actinomycin-D/ Cyclophosphamide, Vincristine (EMA/CO) regimen. Salvage therapy was Etoposide, Paclitaxel /Paclitaxel, Cisplatin (EP/TP). Treatment was continued for three cycles after normalization of β-hCG level, after which the patients were followed up regularly.

Results: In total, 41 GTN patients were treated at our institution during the above period; 17 were in the low-risk and 24 were in the high-risk category. The lung was the most common site of metastasis. All low-risk patients achieved complete remission. Among high-risk patients, one patient died while receiving first cycle chemotherapy, one patient relapsed, and 22 patients achieved complete remission. The single relapsed patient also achieved remission with second-line chemotherapy.

Conclusion: Risk-stratified treatment of GTN was associated with acceptable toxicity and resulted in outcome that was comparable with international standards. The use of two-drug combination in low-risk patients is a better option especially in developing countries.
