Outcomes of relapsed/refractory extracranial germ cell tumors treated on conventional salvage chemotherapy without stem cell rescue: Experience from a tertiary cancer center.

Primary refractory GCTs, extragonadal rel-GCTs, and rel/ref-GCTs with a poor biochemical response did poorly with conventional SC and need alternative treatment strategies. The rel/ref-testicular GCTs had the best chance of salvage despite a second recurrence (5-year EFS and OS: 28.60% and 42.90%, respectively).
