Study Notes
Germ Cell Tumors (GCT)
- Most common malignancy in young men (15-35 years old).
- Standard first-line treatment with cisplatin-based chemotherapy achieves cure rates of 70-80% for metastatic disease.
- Standard regimen bleomycin/etoposide/cisplatin (BEP) results in 90% long-term event-free survival (EFS) rates for advanced-disease, good-risk patients.
- EFS rates decrease to 80% for intermediate-risk patients and 50% for poor-risk patients, according to the International Germ Cell Consensus Classification (IGCCC).
- First relapse patients with standard salvage regimens have 50-60% CR rates and 20-30% long-term EFS.
- Second relapse patients are largely incurable.
High-dose Chemotherapy (HDC) for Refractory/Relapsed NSGCT
- Tandem high-dose cycles of carboplatin/etoposide with autologous hematopoietic progenitor cell support (AHPCS) is used for salvage therapy.
- Nichols et al. pioneered this approach in the 1980s.
- Studies show long-term EFS rates as high as 15% for second-relapse patients and 38% for first-relapse patients.
- Improvements in PBPC techniques and supportive measures have led to higher doses and better results.
- Einhorn et al. found 68% EFS at a 48-month median follow-up in a recent study.
- Outcome is similar in patients with seminoma and non-seminoma histologies.
