Standard chemotherapy for disseminated germ-cell tumors includes a combination of cisplatin, vinblastine, and bleomycin, but this regimen produces substantial neuromuscular toxicity. In a randomized clinical trial in 261 men with disseminated germ-cell tumors, we substituted etoposide for the vinblastine in this regimen in half the patients to compare the efficacy and toxicity of the two treatments. Among 244 patients who could be evaluated for a response, 74 percent of those receiving the regimen including vinblastine and 83 percent of those receiving the regimen including etoposide became disease-free with or without subsequent surgery (P not significant). Among the 157 patients with high tumor volume, 61 percent became disease-free on the regimen that included vinblastine, as compared with 77 percent on the regimen that included etoposide (P less than 0.05). Survival among the patients who received etoposide was higher (P = 0.048). The regimens were similar in terms of myelosuppressive effects and pulmonary toxicity. However, the etoposide regimen caused substantially fewer paresthesias (P = 0.02), abdominal cramps (P = 0.0008), and myalgias (P = 0.00002). We conclude that etoposide with cisplatin and bleomycin is superior to vinblastine with cisplatin and bleomycin in the treatment of disseminated germ-cell tumors because of diminished neuromuscular toxicity and, among patients with advanced disease, better efficacy.

For the first-line treatment of NSCLC, the regimen of gemcitabine plus cisplatin is superior to cisplatin alone in terms of response rate, time to disease progression, and overall survival.

Although the response rate to the combination of CP plus 5-FU was superior to that achieved with single agents, survival did not improve.

Concomitant platin-based radio-chemotherapy may improve survival of patients with locally advanced NSCLC. However, the available data are insufficient to accurately define the size of such a potential treatment benefit and the optimal schedule of chemotherapy.

Sixty-nine patients with disseminated testicular cancer and no prior retroperitoneal lymphadenectomy treated with cisplatin, vinblastine, and bleomycin with or without doxorubicin were evaluated for semen analysis, serum gonadotropins, and testosterone. Since 1979, 41 men have been prospectively studied. Before treatment 77% were oligospermic, 17% were azoospermic, and only 6.6% could meet requirements for sperm banking. After 2 mo of therapy, 96% were azoospermic. A group of 28 patients treated between 1975 and 1979 were retrospectively evaluated. Normal sperm counts were found in 46% of those studied. Only 17% were azoospermic. Thirty-two percent have impregnated their wives, resulting in 5 healthy babies, 1 spontaneous abortion, and 3 ongoing pregnancies. These results show that (1) significant impairment of spermatogenesis exists before therapy, precluding the possibility of sperm banking in most patients, (2) combination chemotherapy in testicular cancer has substantial effects on gonadal function, rendering almost all patients azoospermic, and (3) a high degree of recovery of spermatogenesis occurs sometime after 2-3 yr from the initiation of treatment.

Bleomycin is an essential component of PVP16B therapy in patients who receive three cycles of treatment for minimal- or moderate-stage disseminated germ cell tumors.

Patients obtaining a CR after first-line chemotherapy can be safely observed without PC-RPLND. Relapses are rare and potentially curable with further treatment.

VIP combination chemotherapy is associated with an improved time to progression and overall survival over VP therapy in patients with extensive SCLC.
