Quality of Life in Patients with Advanced Cancer Using the Functional Assessment of Cancer Therapy-General Assessment Tool: A Literature Review

摘要

Quality of life (QOL) has become an increasingly meaningful endpoint in advanced cancer research. Clinicians assess QOL to help them select appropriate treatment options and regimens. The present review aims to compare QOL scores of the Functional Assessment of Cancer Therapy-General Assessment Tool (FACT-G) in relation to clinical and socio-demographic features in patients with advanced cancer. A literature search in MEDLINE and EMBASE was conducted; a total of 33 studies encompassing 39 study arms were identified that reported FACT-G scores. Four statistically significant parameters were identified with respect to FACT-G scores: education, national per capita healthcare expenditures, admittance status and previous radiation therapy. A greater percentage of patients completing higher education programs were correlated to significantly better emotional well-being and global QOL. Cohorts from countries with higher national per capita healthcare expenditures had better physical well-being, social/family well-being and improved relationships with their doctors. Patient samples comprised of purely outpatients had better levels of emotional well-being and global QOL when compared to samples with a mix of outpatients and inpatients. A greater percentage of patients previously receiving radiation therapy were correlated to a better relationship with doctor score. Although limitations of the present review exist, differences in QOL scores based on socio-demographic and clinical factors are observed; certain correlations described in the present work have been described previously in the literature while others have not. Future work aimed at either determining confounding parameters or cause and effect relationships is recommended.doi: http://dx.doi.org/10.4021/wjon594w
