[Clinical phase trial of concurrent chemoradiotherapy combined TS-1 and nedaplatin].
We have treated head and neck carcinoma by concurrent chemoradiotherapy combined with 5-fluorouracil (5-FU) and cisplatin (CDDP). However,this chemoradiotherapy could not show an enormous effect in the advanced carcinoma of Stage III and IV. Therefore,we changed the contents of the chemotherapy, i.e., we replaced 5-FU, one of the agents with time dependency, to continuous administration of TS-1 for 2 weeks,also replacing CDDP, one of the agents with dose dependency, to nedaplatin (CDGP) in order to reduce kidney dysfunction. In this concurrent chemoradiotherapy, oral TS-1 was continued for 2 weeks and CDGP was administered on the 4 th day from the start of TS-1. In addition, radiotherapy was performed concurrently. In this way,we performed a phase I clinical trial of concurrent chemoradiotherapy combining TS-1 and nedaplatin (CDGP). As for the incidence of adverse events,grade 3 mucositis due to radiation was observed in two patients. As a result of the phase I clinical trial,we decided the maximum-tolerated dose (MTD) of TS-1 to be 80 mg/m2 (maximum 120 mg/body) and 100 mg/m2 for CDGP, and then determined the recommended dose(RD) of TS-1 as 80 mg/m2 (maximum 120 mg/ body) TS-1 and of CDGP as 9 0 mg/m2 CDGP.
