Nedaplatin and 5-FU combined with radiation in the treatment for esophageal cancer

A series of patients with esophageal cancer was treated with chemotherapeutic regimens of the new antitumor platinum preparation nedaplatin plus 5-FU in combination with radiation therapy, and the therapeutic responses, side effects, and complications were clinically assessed. There were 2 patients with a complete response and 11 patients with a partial response, hence, a response rate of 76.5%. Major adverse reactions were those of hematological toxicity and included leukopenia (13 patients, 76.5%), thrombocytopenia (8 patients, 47.1%), and lowered serum hemoglobin concentration (9 patients, 52.9%). The leukopenia and thrombocytopenia, though of a grade 3 severity in 3 and 2 patients, respectively, subsided spontaneously in all affected cases. Gastrointestinal adverse reactions were mild and included appetite loss in 7 patients (41.2%) and nausea in 2 patients (11.8%). The only abnormality in renal function observed was a slight elevation of serum creatinine in one patient. The combined therapy of chemotherapy with nedaplatin and 5-FU plus radiation produced a high response rate in the treatment of carcinoma of the esophagus and was associated with reduced gastrointestinal and renal toxicity. The results indicate the combined therapy with nedaplatin to be clinically useful.
