ObjectiveTo assess malignant trophoblastic neoplasia with the standards of the clinical stage and prognostic factor scoring system. MethodsThrough assessing the high-risk factors except clinical stages for 223 patients before treatment according to International Federation of Gynecology and Obstetrics(FIGO) scoring system published in 2000, appropriate treatments were selected for the different patients. ResultsForty-three of 78 cases of choriocarcinomas were with high-risk factors, the other 35 cases were with low-risk factors; 7 of 145 cases of invasive moles were with high-risk factors and the others were with low-risk factors. The primary chemotherapy principle was that one agent was used for those patients with low-risk factors and two or multiple-agents were used for those patients with high-risk factors. Among all patients, the one-year, three-year and five-year survival rates were 98.6%,98.1% and 97.1% respectively. No patient died of drug toxicity or complication. ConclusionSelection of treatment approaches according to the prognostic assessment of malignant trophoblastic neoplasia could lead to promising survival rate with no uncurable complication and toxic effects.

OBJECTIVETo evaluate the results of Gynatron low dose rate (LDR) brachytherapy for cancer of uterine cervix.
METHODSFrom April 1980 to June 1986, 136 patients with uterine cervical carcinoma were given radical radiotherapy through LDR afterloading irradiation and (60)Co external irradiation, compared with those through radium and high dose rate (HDR) intracavitary therapy.
RESULTSAll patients except 5 were followed up for 15 years with a follow-up rate of 96.3% (131/136). The overall 10-year survival rate was 63.5%. The 10-year survival rates of stage II and III patients were 83.9% and 43.2%. The frequency of proctitis and cystitis were 12.5% (17/136) and 9.6% (13/136).
CONCLUSIONGynatron LDR system has achieved good results with tolerable complications including proctitis and cystitis which are more often than those of radium and less so than those of HDR.

OBJECTIVETo evaluate the feasibility of surgical management for patients with locally advanced carcinomas of uterine cervix after radical radiation therapy who were prone to develop central recurrence.
METHODSThese 40 patients were treated by combined pre-operative radiotherapy with dose at point A of > 70 Gy in 30 patients, 60 approximately 70 Gy in 7, 50 approximately 59 Gy in 2 and 44 Gy in 1. The interval between radiation and surgery was 1 - 6 weeks. Extrafascial hysterectomy was performed in 15 patients, subradical hysterectomy in 23 and radical hysterectomy with pelvic lymphadenectomy in 2 cases.
RESULTSThese patients have been followed up for 1 - 8 years with 2 died of other diseases and 12 died of cancer. Eighteen of the 26 survivors have been followed up for more than 5 years. The 3- and 5-year survival rates were 74.9% and 66.8%. Half of the death occurred within the first year after treatment. The 2-year death rate was 9/12 (75.0%). Three patients suffered from long term complications after the treatment, but all were cured by conservative management.
CONCLUSIONThe combination of hysterectomy performed shortly after radical radiotherapy, ie, for patients with locally poor prognostic cervical carcinoma is reasonable and feasible.
