The Relationship between Supportive Care Needs and Health-Related Quality of Life in Cancer Patients

The aim of this study was to analyze the relationship between quality of life (QoL) and supportive care needs (SCNs) in cancer patients. It is difficult to relate SCNs to detriments in QoL since SCNs and QoL assessment tools generally comprise different dimensions that cannot be directly related to each other. Therefore, we developed a short questionnaire with eight dimensions for uniformly measuring SCNs, QoL, and the subjective importance of these dimensions. A total of 1108 cancer patients with mixed diagnoses assessed eight dimensions of health-related QoL concerning SCNs, satisfaction, and importance. Among the eight dimensions of QoL, physical functioning received the highest SCN assessments (M = 3.4), while autonomy (M = 20.7) and social relationships (M = 1.88) were the dimensions with the lowest SCN mean scores on the 1–5 scale. For each of the eight dimensions, high levels of SCNs were reported by those patients who had low levels of satisfaction with that dimension (r between −0.32 and −0.66). The subjective importance of the dimensions was not consistently correlated with SCNs (r between −0.19 and 0.20). Females reported higher SCNs than males in six of the eight specific dimensions. Patients with prostate and male genital cancers reported the lowest SCNs. These results suggest gender-specific SCN patterns that warrant further exploration. This study highlights the value of a unified assessment instrument for SCNs and QoL, providing a robust basis for future cancer care strategies.
