Methods A retrospective review was conducted on 56 patients with GTD who under- went treatment in Ruijin hospital from January 2007 to December 2012. Their infor- mation of diagnosis, treatments, follow-up and efficacy were collected and analyzed Results Misdiagnosis rate was 41.1% （23/56）for the first time. Of 56 patients, 31 had direct curettage, 19 had curettage after trichosanthis （TCS） treatment, 3 had curettage after intervention treatment and 3 did not have curettage. Twenty patients with gesta- tional trophoblastic neoplasia （GTN） took fluorouracil＋vincristine＋dactinomycin （VCR ＋KSM＋5-FU） chemotherapy, but 2 of them changed to etoposide＋methotrexate＋acti- nomycetes streptozotocin-D＋cyclophosphamide＋vincristine （EMA-CO） chemo- therapy due to drug resistance. Three patients＂ with GTN took EMA-CO chemotherapy. Two patients with placental site trophoblastic tumor （PSTT） required surgeries, one took hysterectomy, another got mass and adnexectomy. Apart from 1 case who gave up treatment and was dead, all the other women went into remission from their diseases. Conclusion The diagnosis of trophoblastic disease rely on a comprehensive analysis. A reasonable choice of TCS or intervention can be effective and safe in treating GTD. Most patients with GTN could get complete remission by selecting the appropriate chemotherapy and surgery.展开更多
