The study of quality of life in cancer patients has several objectives which must be considered separately, even if they are combined in the same work: The descriptive finality constitutes the first mandatory step of any further study and must take into account all the psycho-social parameters involved in cancer disease and its treatment. The causative finality attempts, on basis of correlations between these parameters, to define the psycho-social factors involved in carcinogenesis and disease course. The therapeutic finality includes the study of quality of life in medical decision making, psychotherapeutic intervention as well as evaluation of various treatments aimed at improving quality of life of cancer patients.
对癌症患者生活质量的研究有几个目标，即使它们在同一研究中结合在一起，也必须分别加以考虑：描述性目的是任何进一步研究的首要必要步骤，必须考虑到癌症疾病及其治疗中涉及的所有心理社会参数。因果性目的基于这些参数之间的相关性，试图确定参与致癌作用和疾病进程的心理社会因素。治疗性目的包括在医疗决策、心理治疗干预中对生活质量的研究，以及对旨在改善癌症患者生活质量的各种治疗方法的评估。
