Study Notes
Germ Cell Tumors & Treatment
- Germ cell tumors (GCTs) are the most common cancer among young men (ages 15-35).
- Cisplatin-based chemotherapy has significantly improved cure rates for metastatic GCTs, reaching 70-80%.
- The standard first-line regimen (BEP) leads to long-term event-free survival (EFS) of 90% for good-risk patients with advanced disease, according to the International Germ Cell Consensus Classification (IGCCC).
- The EFS rate for intermediate-risk patients with advanced disease drops to 80% using the BEP regimen.
High-Dose Chemotherapy for Refractory GCTs
- High-dose chemotherapy (HDC) is considered for patients with relapsed or refractory GCTs.
- Tandem high-dose cycles of carboplatin/etoposide with autologous hematopoietic cell transplantation (AHPCT) have shown improved EFS rates for patients in their second (15-38%) and first (38%) relapse.
- Early studies by Nichols et al., initiated in the 1980s, and subsequent dose re-escalation improvements have contributed to enhanced results.
- A study by Einhorn et al., with a median follow-up of 48 months, included 184 patients (135 transplanted in second-line and 49 in third-line or later). This study indicated an EFS rate of 68%.
- Tandem cycles of carboplatin (2,100 mg/m²) and etoposide (2,250 mg/m²) yielded similar EFS rates in patients with seminomas and non-seminomas (74% vs. 60%).
