The Phase I stage aims to explore the maximum tolerated dose (MTD) of TAS-102 in elderly esophageal cancer patients. A total of 9 subjects were enrolled, and the dose was escalated from 30 mg\u002Fm² in 5 mg\u002Fm² increments up to 40 mg\u002Fm². The MTD was defined as the highest drug dose at which no dose-limiting toxicity (DLT) was observed in more than 40% of treated patients during the first two weeks of combined radiotherapy and TAS-102 administration. The Phase II stage aims to investigate the efficacy of radiotherapy combined with TAS-102 at the MTD in elderly esophageal cancer patients, with 36 subjects enrolled.\n\nConsolidation Phase: Following the treatment phase, subjects had a 3-4 week rest period. This was followed by consolidation therapy with TAS-102 monotherapy at a dose of 35 mg\u002Fm², administered twice daily on days 1-5 of a 28-day cycle for two cycles.\n\nSubsequently, patients entered the efficacy and safety follow-up phase until the study endpoints were reached or after a full 2-year follow-up period.",[72,73,23],"ESCC","TAS 102","NOT_YET_RECRUITING","2025-09-21",{"date":77,"type":78},"2025-09-29","ACTUAL",{"date":80,"type":65},"2025-09-25",{"date":82,"type":65},"2028-12-31",{"name":5,"class":6},1]
