[Treatment of inoperable non-small cell bronchogenic carcinoma with a combination of cisplatin and vinorelbine--preliminary evaluation]

Abstract

The optimal therapeutic approach to patients with inoperable non-small-cell carcinoma is still a matter of discussion. The reason is that chemotherapy improves the quality of life only in some patients. It prolongs their life only by several weeks. In recent years in this indication a new cytostatic is tested--vinorelbine which when used in monotherapy achieves a therapeutic response in 16--30%. In clinical trials of phase 2 a combination of vinorelbine and cisplatinum was most effective and therefore it was selected for the third phase of clinical trials. In the Czech Republic a clinical investigation was made with the objective to verify published data on the success of treatment, evaluate undesirable effects and consider whether it is suitable for routine use. Cisplatinum (Platidiam Lachema) was administered--80 mg/m2 on the first day, vinorelbine (Navelbine Pierre Fabre)--30 mg/m2 on the first and eighth day. The cycle was repeated on the 22nd day. All patients were treated for 12 weeks. Then followed the first evaluation and treatment was continued only in patients with regression or stabilization of the disease. In the group of 126 patients in 44 (35%) partial and in 3 (2.3%) complete therapeutic responses were obtained. In 35 (27%) the disease was evaluated during treatment as stabilized, in 38 (30%) of the patients the disease progressed despite treatment. The tolerance of treatment was, when effective antiemetic treatment was used (ondansetrone or granisetrone), relatively satisfactory.
