[Comprehensive staging surgery in treatment of malignant ovarian germ cell tumor]

To evaluate the impact of comprehensive staging surgery on relapse and survival of malignant ovarian germ cell tumor (MOGCT).

The clinical data of 127 MOGCT cases treated in Peking Union Medical College Hospital from June 1980 to June 2003 were analyzed retrospectively. All the data about comprehensive staging surgery during primary surgery were collected, and other factors related to prognosis were also collected at the same time. COX model was applied in multivariate analysis related to relapse and survival.

Among 127 patients, 45 (35.4%) received comprehensive staging surgery. Seventy-one cases (55.9%) received satisfied cytoreduction with residual tumor < 2 cm, 11 cases (8.7%) with residual tumor > or = 2 cm, and another 45 cases (35.4%) were undetermined. Seventy-five cases (59.1%) received cisplatin, etoposide, and bleomycin (BEP) or cisplatin, vinblastine, and bleomycin (PVB) chemotherapy, 18 cases (14.2%) received vincristine, actinomycin D, cyclophosphamide (VAC) chemotherapy, and 34 cases (26.8%) received other regimens or no chemotherapy. During the follow up period, 7 of 45 patients relapsed in patients who received compressive staging surgery, while the latter was not a significant factor (P = 0.061). Chemotherapy regimen and residual tumor were the significant factors related to the relapse (P < 0.05). All the patients were followed up for 2-254 months. Chemotherapy regimen and residual tumor were also the significant factors related to survival (P < 0.05). Compressive staging surgery showed no significant effect on survival (P > 0.05).

The critical treatment for MOGCT is satisfactory cytoreduction surgery plus standard chemotherapy. Comprehensive staging surgery shows no significant impact on the prognosis of MOGCT patients.
