Consolidative high-dose chemotherapy (HDCT) after conventional-dose chemotherapy (CDCT) as first salvage treatment for male patients (pts) with metastatic germ cell tumors (mGCTs).

336 Background: Some men with mGCTs progressing after response to initial cisplatin-based combination chemotherapy are cured with CDCT as 1st salvage, however, many are not. Prognosis has recently been better defined by the IPFSG prognostic factors. HDCT with autologous stem cell rescue has been routinely offered after CR/PRm- remission with CDCT at our institution over the past two decades. We retrospectively reviewed our data to assess the validity of the IPFSG prognostic factors and evaluate the potential value of this approach. Methods: Eligible men with mGCTs progressing after at least 3 cycles of cisplatin-based chemotherapy received after 01 Jan 1990 and treated with cisplatin-based CDCT+/−HDCT (etoposide + carboplatin) were identified and data collected. Pts were classified into risk groups using IPFSG factors, PFS and OS were analyzed and results for CDCT+/−HDCT compared. Results: 38 eligible 1st salvage pts had received a median of 4 cycles (range, 1–7) of CDCT. 20 pts received CDCT alone & 18 p...
