Intensive chemotherapy in poor-prognosis nonseminomatous germ cell tumors of the testis.
Forty-one patients with poor-prognosis nonseminomatous germ cell tumors (NSGCT) of the testis were treated between 1980 and 1989. This group was defined by the presence of one of the following features: multiple large lung metastases, bone, liver or brain metastases, abdominal mass greater than 10 cm, abdominal mass greater than 5 cm with high serum concentration of the tumor markers [alpha-fetoprotein (alpha FP) greater than 500 kU/l or beta-subunit of human chorionic gonadotropin (beta HCG) greater than 1,000 IU/l) or very high serum tumor marker concentrations (alpha FP greater than 5,000 kU/l or beta HCG greater than 10,000 IU/l). The first 21 patients were treated with cisplatin, vinblastine, bleomycin (PVB) chemotherapy and the following 20 with an intense, alternating 6-drug chemotherapy consisting of cisplatin, bleomycin, vincristine, methotrexate, etoposide and ifosfamide (BOMP/EPI). Surgery of residual masses was performed when tumor markers were negative. Fifteen patients (71.4%) in the PVB group and 18 patients (85%) in the BOMP/EPI group remained disease-free at a median follow-up of 67 and 41 months, respectively. None of the resected masses in the BOMP/EPI group contained malignant disease whereas viable carcinoma was found in 5 of 14 (26.4%) patients in the PVB group. The toxicity of the BOMP/EPI regimen was severe but tolerable. Intensive chemotherapy regimen seems to be useful in this subset of patients, but randomised prospective trials comparing these with standard chemotherapy are necessary.
