Quality of life (QL) is an expression of the degree to which a tumor patient is satisfied and copes with his life and the therapy which is being administered. QL is influenced by physical, psychological and social factors as well as by time. During the individual course of a malignant disease and its therapy, changes in QL need to be assessed with the appropriate "measuring instruments". Once the quality of the data has been assured, comparisons can be made with respect to the influence of alternative therapies on QL. This is where "promotional" information from the pharmaceutical industry can be emphasized; QL degenerates to a useless term, however, if it is used indiscriminately and without proper validation of the data. A new concept, i.e. QUALYs (= Quality Adjusted Life Years), has originated in the USA, which attempts to add a dimension of currency value to the term LQ.
生活质量（QL）是指肿瘤患者对其生活及所接受治疗的满意程度和应对能力的一种体现。生活质量受到身体、心理和社会因素以及时间的影响。在恶性疾病及其治疗的个体过程中，需要使用适当的“测量工具”来评估生活质量的变化。一旦数据质量得到保证，就可以比较不同治疗方法对生活质量的影响。这正是制药行业“推广”信息可以得到强调之处；然而，如果不加区分地使用且不对数据进行适当验证，生活质量就会沦为一个无用的术语。一个新的概念，即质量调整生命年（QUALYs），起源于美国，它试图给生活质量这个术语增添货币价值的维度。
