目的:探讨食管癌病人同步放化疗期间不同时间点症状群的动态变化。方法:选取2022年2月—10月在四川省某三级甲等医院肿瘤内科治疗的102例食管癌病人作为研究对象。于放化疗开始前、放疗10次、放疗20次、放疗结束时采用一般资料调查表、中文版安德森消化道癌症症状评估量表对病人进行调查,采用探索性因子分析法提取症状群。结果:食管癌病人同步放化疗期间不同时间点各症状发生率及严重程度有所不同,其中吞咽困难、疼痛、疲乏、昏昏欲睡的发生率及严重程度均较高。探索性因子分析结果显示,在放化疗开始前、放疗10次、放疗20次、放疗结束时分别提取4、5、4、4个症状群,其中,心理-身体不适症状群、消化道症状群、进食困难症状群持续存在,睡眠不足症状群存在于放化疗开始前、放疗10次,不良反应症状群从放疗10次开始出现。结论:食管癌病人在同步放化疗期间存在多个症状群,部分症状群持续存在,各时间点症状群构成不尽相同,严重程度存在差异。医护人员要加强食管癌病人同步放化疗期间的症状管理,完善管理方案,以减轻病人的症状负担。
