The role of high-dose chemotherapy in relapsed germ cell tumors.
Overall, patients with relapsed or progressive germ cell tumors after cisplatin-based chemotherapy have a low chance of cure. Using conventional-dose chemotherapy (CDCT) as salvage treatment, only 15-30% of the patients will become long-term survivors. It is well known that the majority of these patients will ultimately die of their disease. Therefore, improvement of the standard treatment is clearly desirable. In the last years, high-dose chemotherapy (HDCT) has been established as an effective salvage modality. A matched-pair analysis showed an advantage for HDCT compared with CDCT with an improvement in event-free and overall survival. Furthermore, due to increasing clinical experience in the management of side-effects, the use of peripheral blood progenitor cells and the availability of hematopoietic growth factors, HDCT has become relatively safe. Therefore, HDCT should be administered in patients with first relapse and unfavorable prognostic factors, and as second or subsequent salvage treatment followed by complete resections of tumor residuals. Patients with relapse or progressive disease after HDCT who do not qualify for desperation surgery could be salvaged with palliative chemotherapy combinations using gemcitabine, oxaliplatin and paclitaxel. This report reviews the current treatment strategies and recent developments with respect to HDCT given as salvage treatment and discusses the role of prognostic factors in the management of such situations.
