Methotrexate as a single agent chemotherapy in most women with low risk gestational trophoblastic neoplasia (GTN) has been associated with high treatment rate. Combination of methotrexate with Vitamin A due to reduced number of chemotherapy regime courses is one of the treatment options for patients with low-risk GTN. Therefore, this study was performed with aim to determine the efficacy of combination therapy of Methotrexate with Vitamin A in low risk GTN treatment. This randomized clinical

The treatment group (Group A = 19 cases) weekly received Methotrexate 50 mg/m 2 , and Vitamin A 200000 IU, intra-muscular, and the control group (Group B = 30 cases) only received Methotrexate 50 mg/m 2 weekly. All patients were followed up for 8 weeks. Then, treatment outcomes were compared between two groups, and response to therapy was assessed in two groups by evaluation of HCG serum level. P < 0.05 was considered significant.Mean of B-HCG serum level after 4 weeks in Group A and Group B was 68.5 mIu/mL and 360 mIu/mL, respectively (P = 0.018), and after 8 weeks was 1 mIu/mL and 12 mIu/mL, respectively (P = 0.074). Combination therapy of Methotrexate and Vitamin A in low risk GTN is associated with shorter duration of chemotherapy.
