摘要
本文分析了５３５例６５岁以上的老年食管癌放射治疗的远期疗效，全部病人随访均在５年以上，１、３、５年生存率分别为５０．５％、２０．７％、９．９％，病变部位对生存率不表现出明显的影响，病变长度对生存率有肯定的影响，即病变越短生存率越高且有统计学意义，总剂量对生存率的影响表现在大于７０００ｃＧｙ组生存率最低，故我们认为对老年食管癌的放疗不宜追求过高剂量，近期疗效与生存率呈平行关系即近期疗效好生存率较高。
Abstract From 1969 to 1984,535 old age patients with esophageal carcinoma were treated by radiotherapy.All patients were more than 65 years old.They were followed up for more than fiveyears.The 1.3 and 5 year survival rates were 50.5%.20.7% and 9.9%.The 5 year survivalrate of more than 65 years old patients could get the same results as that younger patients. Theshorter tumor length,the higher survival rate.The high tatal dose is not suitable for the treatment of radiotherapy in old patients.In a word,the radiotherapy of the old patients of esophagealcancer must give a same treatment as that of younger patients.
