Extragonadal germ cell tumors: clinicopathologic findings, staging and treatment experience in 14 patients.J Exp Clin Cancer Res. 2000 Sep; 19(3):281-5.JE
Extragonadal germ cell tumors (EGCT) are a rare group of neoplasms histologically identical to testicular counterparts. Fourteen cases of primary mediastinal and retroperitoneal germ cell tumors were treated with chemotherapy and radiotherapy between 1987 and 1999 in Ankara Oncology Hospital. There were 9 (64%) complete remissions (CR),one (7%) partial remission (PR) and 2 (14%) stable diseases (SD). The remaining 2 patients were lost due to dissemination of disease. The median duration of response was 19 months. Our modified chemotherapeutic results were similar to original doses of PVB and BEP but toxicity was less. The neccesity of a uniform staging system and treatment programs are discussed.
