High-dose chemotherapy with autologous PBSC transplantation for poor prognosis germ cell tumors: a retrospective monocenter analysis of 44 cases.
Germ cell cancer (GCC) is curable in metastatic stages. The International Germ Cell Cancer Collaborative Group (IGCCCG) reports a poor prognosis subgroup with a 5-year survival of 48%. High-dose chemotherapy with PBSC transplantation (HD-PBSCT) in these patients showed promising results in phase II, but failed to show significant advantage in randomized trials. We report our monocenter series of all poor and selected intermediate prognosis germ cell tumor patients treated with multiple-course HD-PBSCT and secondary surgery of remaining tissue. We performed a retrospective analysis of our complete series of 44 patients (40 poor prognosis and 4 intermediate prognosis) treated by HD-PBSCT as part of first-line therapy from 1999 to 2010. The CR rate after up to four cycles of HD-PBSCT and radical resection of residual manifestations was 73%. The 3-year survival rate was 79.5% (median follow-up of 51.5 months; range: 7-143 months). Disease-related death rate was 16%. HD-PBSCT-related death did not occur. One patient died postsurgery. Multiple courses of HD-PBSCT with radical secondary surgery is safe and effective in poor prognosis metastatic GCC. Despite disappointing phase III studies it is of high interest to further study this field.
