Cisplatin containing combination chemotherapy of advanced germ cell line testicular tumours.

One hundred ninety patients with germ cell line testicular tumours were treated according to the modified Einhorn scheme. The response rate was 67.9%. The most favourable results were found in the embryonal histologic type (RR = 76.9%) in the biological markers (beta-HCG and AFP) negative (RR = 97.4%) and in the minimal pulmonary extent group (RR = 94.1%). The authors treated 112 patients with including these VPB-resistant germ cell testicular tumour and those with recurrence after this treatment. The patients' mean age was 28.8 (limits 19 to 44) years. Patients were given Vepeside (100 mg/m in infusion for days 1-5), Adriablastin (40 mg/m in infusion on day 1) and Cisplatin (20 mg/m in infusion) for day 1-5. The treatment resulted in CR with 18 patients (16.1%) and PR with 42 (37.5%) (RR = 53.6%). The best results were obtained with the seminoma patients who were marker-negative and had small-volume metastasis. CR developed in 4 of 7 seminoma patients (57%) and in 7 of 25 marker-negative individuals (28%), and PR developed in 11 patients (44%) (RR = 72%). Out of 12 patients with small volume metastatis four (33%) showed CR and five revealed PR (41.7%), their RR turned out to be 74.6%. The average remission period was 37 (range 4-70) months in CR but merely 6.1 (range 2-38) months in PR. It can be stated that fairly good results can be achieved with second-line VpAP treatment in case of resistance developed to primary VPB therapy or subsequent relapse. The efficacy of combined chemotherapy of Vepesed+Holoxan +/- Adriablastin as third-choice was studied in advanced testicular cancer patients refractory to, or recurrent after, first- and second-line cytostatic therapy. Between September 1981 and January 1988 49 evaluable patients were treated with Vepesid (VP-16213--100 mg/m2 days 1-5), Holoxan (40 ml/kg days 1-5), hydration, urine-alkylation + Uromitexan +/- Adriablastin (40 mg/m day 1). The single dose of Uromitexan was 20% of the daily dose of Holoxan, and the patients received it i.v. just prior to Holoxan administration (h 0), the 4 and 8 h later. Two patients got into CR and 10 to PR. The rate of remission was 24.5%. The most severe side effect was leukopenia. The elevation of BUN and se. creatinine was transient and mild. In those cases where Holoxan was not included in the first- or second-line regimens, when combined with Vepesid and Adriablastin as third-choice therapy one could achieve further improvement. In case of CR the prolongation of life is also noteworthy. The first-, second- and third-line therapy plus salvage RLA and/or pulmonary metastasectomy achieved long-term survival only in one quarter of the patients.
