Salvage Chemotherapy for Relapsed or Refractory Disease

For patients with good prognostic factors at first relapse, salvage chemotherapy (four cycles of standard dose) is recommended. The regimens of choice are four cycles of PEI/VIP (cisplatin, etoposide, ifosfamide), four cycles of TIP (paclitaxel, ifosfamide, cisplatin) or four cycles of VeIP (vinblastin, ifosfamide, cisplatin). In patients with poor prognostic features at relapse

and for all patients with second or subsequent relapse, high-dose chemotherapy plus autologous stem cell support is suggested.42 These patients should be treated at specialized highvolume centers and within prospective randomized studies.

Conclusion

Chemotherapy has a place in selected patients with testicular cancer. Future research will focus on further reduction of chemotherapy’s related morbidity without compromising the high rates of cure.
