文摘

The objective of this study was to compare the health-related quality of life (HRQL) burden across different types of advanced cancer with the use of 2 widely used patient-reported outcome measures, the generic EQ-5D and the cancer-specific Functional Assessment of Cancer Therapy-General (FACT-G).

Methods

Patients with advanced cancer of the bladder, brain, breast, colon/rectum, head/neck, hepatobiliary tract/pancreas, kidney, lung, lymphoma, ovary, or prostate completed the EQ-5D and FACT-G. HRQL domains and summary scores were compared across types of cancer, using regression models to adjust for age and sex.

Findings

Approximately 50 patients with each type of cancer were recruited (total, 534 patients). According to EQ-5D dimensions, the highest proportion of problems was associated with prostate (mobility); prostate and kidney (self-care); head/neck, bladder, and lung (usual activities); breast, head/neck, and lung (pain/discomfort); and lymphoma and lung (anxiety/depression) cancers. EQ-5D visual analogue scale scores were lowest for breast and head/neck cancers; US index-based scores were lowest for breast and lung cancers and highest for brain cancer. For the FACT-G, physical well-being scores were lowest for head/neck, hepatobiliary, and kidney cancers; emotional well-being scores were lowest for hepatobiliary cancer, and functional well-being scores were lowest for head/neck, hepatobiliary, and bladder cancers.

Implications

The overall and dimension-specific HRQL burden of advanced cancer depended on the type of cancer. Such results may aid clinicians and patients in better understanding of how cancer site can affect HRQL and functioning in different ways.
