Abstract
16031 Background: To evaluate the clinical behavior and results of treatment of gestational trophoblastic disease at INEN between 1980 to 2005. Methods: This is a retrospective analysis of patients with gestational trophoblastic disease, clinical characteristics, results of treatment, toxicity, objective response and survival from January 1980 to December 2005. Descriptive statistics and Kaplan-Meier for survival analysis were performed. Results: Since Jan 1980 to Dec 2005. 595 patients were admitted at INEN; Hydatidiform mole 254 (42.7%) choriocarcinoma 201 (33.8%) invasive mole 41(6.8%). FIGO scoring System, high risk (score >6): 247 (41.5%), low risk (score 1–6): 348 (58.5%). Age ranged from 14 to 54 years, with 255 (44%) cases between 20 to 29 years. The sities of metastasis: lung 67.3%, vaginal 17.9%, brain 8.7%, liver 5.1%. The patients with low risks received treatment with Metotrexate 0.4mg/kg x day x 5 days po, reach disease control with a mean course of 6 (1 - 14), complete remission in 66.1% cases and 97% the overall survival rate to 20 years. Patients with high risk received treatment with: MAC 77 patients, MEC 19 patients, EMACO 48 patients and BEP 14 patients and achieved complete remission in 32.5%, 36.8%, 50% and 25% respectively. On the high risk group we detected two groups according to score > 12 and < 12, with diferent probability of survival at 20 years, for the group with score <12, 80% and the group with score >12, 48%. 98 patients were identified with score >12, and the age of these patients ranged from 15 to 51 years, with a mean age of 36.5 years. The blood B- HCG titers of these patients ranged from 198 to 6710,500. Liver and brain metastasis in 26 cases, number metastasis mayor 8 in 78 cases. Conclusions: Gestational trofhoblastic disease is highly curable. Patients of low risk achieved a 97% overall survival rate to 20 years. There are differences in the overall survival rate between patients of high risk with a score < 12 (80%) and score >12 (48%). This group presented with brain and liver metastasis, and it is important to define the best treatment for this group of patients No significant financial relationships to disclose.
