Abstract

Studies using simultaneous radiation therapy and conventional doses of cisplatin have suggested improvement in local control and patient survival. This study was undertaken to determine toxicity and patient tolerance to concomitant high-dose cisplatin (40 mg/m2 per day X 5) and radiation (60 Gy in 6 wk +/- 10-Gy boost to residual tumor). Seventeen patients with advanced, inoperable squamous cell cancer primary tumor in the head and neck were treated (15 males and 2 females; median age, 57 yr). Cisplatin was started on day 1 of radiation therapy and repeated every 28 days for three cycles. Normal saline infusion (250 ml/hr) was started 12 hours prior to the first dose and continued 12 hours after the fifth dose. The daily dose of cisplatin was dissolved in 250 ml of 3% NaCl and given over 30 minutes. The cisplatin dose for subsequent cycles was reduced 10 mg/m2 per day only for a nadir granulocyte count less than 500/mm3 or fever greater than 101 degrees F during leukopenia. Of the 17 patients who started therapy, 15 have completed therapy; 1 patient died after one cycle, and 1 died after two cycles. Eleven patients received three cycles of cisplatin, and 10 patients required one dose reduction (6 at course 2 and 4 at course 3). Seven possible infections were successfully treated. Grade 2 neuropathy occurred in 3 patients, and renal toxicity greater than grade 1 occurred in 1 patient. Additional toxic effects were median WBC count nadir of 1.8 X 10(3)/mm3, platelet count nadir of 128 X 10(3)/mm3, hemoglobin nadir of 9.8 g/dl, and median weight loss of 5%.(ABSTRACT TRUNCATED AT 250 WORDS)
