Cisplatin, vindesine, and bleomycin chemotherapy of local-regional and advanced esophageal carcinoma

Abstract

Seventy-one patients with epidermoid carcinoma of the esophagus were treated with a three-drug combination of cisplatin, vindesine, and bleomycin. Forty-five patients had local-regional tumor and received chemotherapy prior to surgery or radiation therapy. Twenty-six patients with extensive disease were treated primarily with chemotherapy alone. The overall major objective response rate to cisplatin-vindesine-bleomcyin was 53 percent (36 of 68 evaluable patients). Patients with local-regional disease had a higher response rate than those with extensive disease (63 and 33 percent, respectively). Following preoperative chemotherapy, 34 patients with local-regional disease underwent exploration. Resectable disease was present in 82 percent. There was no increase in operative morbidity or mortality (5.6 percent), when compared with historical control groups. The median survival for the preoperative chemotherapy group was 16.2 months, which is superior to that of a historical control group (p = 0.023). For patients with extensive disease, treated primarily with chemotherapy alone, the median duration of response was seven months. Toxicities of cisplatin-vindesine-bleomycin were in general well-tolerated, and included nausea and vomiting (seen less frequently because of extensive use of metoclopramide), alopecia, nephrotoxicity, and peripheral neuropathy. The dose-limiting toxicity was myelosuppression. Although conventional chemotherapeutic agents have little activity, these results indicate that the investigational combination of cisplatin, vindesine, and bleomycin can induce major regressions in a substantial proportion of patients with esophageal cancer. When this drug combination is used preoperatively, high resection rates and possibly improved survival are seen.
