The change of target variables in palliative cancer treatment led to a new evaluation of quality of life. Its use as a target variable to discriminate different therapies is problematic. Investigations with a patient-questionnaire assessing quality of life showed that the validity of this term is difficult to judge. At present it should be used in clinical research as an accompanying variable only.
姑息性癌症治疗中目标变量的变化引发了对生活质量的重新评估。将其用作区分不同治疗方法的目标变量存在问题。通过患者问卷评估生活质量的调查表明，这个术语的有效性难以判断。目前，它仅应作为一个伴随变量用于临床研究。
