Cisplatin, etoposide, ifosfamide, vincristine and bleomycin combination chemotherapy for far advanced testicular carcinoma.

Forty-eight patients with advanced testicular cancer, defined as abdominal mass greater than 10 cm, mediastinal mass greater than 5 cm, more than 20 lung metastases, or visceral organ involvement were treated with an intensive, alternating five-drug regimen consisting of cisplatin 50 mg/m2 d 1-3, etoposide 170 mg/m2 d 1-3, ifosfamide 5 g/m2 d 15, vincristine 2 mg weekly, bleomycin 15 mg/m2 weekly, q d 28. Thirty-four (71%) of the patients attained tumor-free status. This was achieved by chemotherapy alone in 14 patients and by surgical resection of residual disease in the remaining 20 patients (histology of resected tissue: necrosis 12, mature teratoma 7, viable carcinoma 1). Patients with pure seminoma responded better than patients with nonseminoma (CR 100% vs. 67%, respectively). In a univariate analysis only the value of HCG (less than vs greater than 10,000 U/L) and the number of involved organ sites (less than or equal to 2 vs greater than to 2) had significant influence on the response rate. After a minimum follow-up of 24 months 3 patients (9%) have relapsed. The survival rate is 76% after 36 months, with 61% remaining disease-free. Though this intensive regimen might bestow some of the therapeutic advantages of standard three-drug protocols in far advanced testicular cancer, the results are still less than optimal and warrant the exploration of new therapeutic strategies.
