Abstract
OBJECTIVE: To study risk factors associated with the number of chemotherapy courses required to obtain normal beta-human chorionic gonadotropin (beta-hCG) levels and evaluate the effectiveness of combination chemotherapy using 5-fluorouracil (5-FU) and actinomycin D (Act D) (FA) for gestational trophoblastic neoplasia (GTN). STUDY DESIGN: A retrospective study of GTN cases from January 1995 to July 2007 at the Beijing Obstetrics and Gynecology Hospital was performed. RESULTS: During the study period, 240 cases of GTN were diagnosed and managed at our institution. A stepwise regression analysis revealed that the interval between evacuation and chemotherapy, parity, age and beta-hCG level were associated with number of chemotherapy courses required to obtain normal beta-hCG levels. In addition to 4 patients with placental site trophoblastic tumor, FA was used in 218 patients (136 low risk and 82 high risk). CONCLUSION: Early detection of GTN and timely administration of chemotherapy decreases the number of chemotherapy courses required. The combination chemotherapy of 5-FU and Act D is effective in low- and high-risk patients with GTN, but not in patients with placental site trophoblastic tumor; it can be used as primary chemotherapy regimen in high-risk patients with GTN, except those with extensive metastases.
