Gestational trophoblastic disease: Experience at a tertiary care center from a developing country
16041 Background: We retrospectively analyzed case records of patients diagnosed to have Gestational Trophoblastic Disease (GTD) to determine clinical characteristics, risk groups, treatment outcome, and reproductive function post treatment. Methods: Between Jan 1991 to Dec 2005, 102 patients (mean age: 28.2 years, range 19–50) were diagnosed to have GTD. 35 patients were nulliparous and 8 had prior molar pregnancy. Vaginal bleeding was the most common presenting symptom (77.5%). The antecedent pregnancy was vesicular mole in 50%, abortion - 34.3%, ectopic pregnancy - 4% and term pregnancy in 11.8% patients. The mean value of B hCG was 1225386 mIU/ml. The histopathology (n=85) was complete mole in 30, partial mole - 28, invasive mole- 9, PSTT -1 and choriocarcinoma in 17 patients. 68(66.7%) patients had non-metastatic disease. Sites of metastasis were - lung (38.2%), vagina (11%), brain (8.8%), liver (6.9%) and kidney, Urinary bladder and peritoneum in one patient each. According to modified WHO risk scoring - 78(76.5% had low risk and 24 (23.5%) were high risk. Results: Eighty-seven (85.3%) patients received chemotherapy using methotrexate with leucovorin (n=63), EMA/CO (n=19) and BEP (n=5). 77/87 (89.5%) achieved complete remission (CR) ; the response rate was higher in non-metastatic GTD (p<0.05). Two of 7(28.6%) patients with liver and 5/9 (55,6%) of brain metastasis achieved CR. Two patients had grade III oral mucositis and diarrhoea with methotrexate. One patient died of Methotrexate hypersensitivity. 19 patients received second line chemotherapy using EMA/CO (n=11), EMA/EP (n=2), BEP (n=1), actinomycin-D (n=1) and MAC (methotrexate, actinomycin D and Cyclophosphamide) n=1; 14 patients achieved CR. At a mean follow up of 180 months, 5-year survival for patients with low risk is 100% and that of high risk is 95%. Eight patients had recurrent disease including recurrent molar pregnancy in four. 16 patients had 24 successful deliveries after completion of treatment and 10 of them were primiparae. No fetal abnormalities were found. We did not observe second malignancy or other therapy related sequele. Conclusions: Present study confirms excellent outcome for patients with gestational trophoblastic disease. The potential for childbearing is well maintained. No significant financial relationships to disclose.
