Comparison of changes in health-related quality of life between elderly and non-elderly patients undergoing elective surgery for colorectal cancer

PurposeElderly people are thought to be more likely than their non-elderly counterparts to experience a decline in activities of daily living (ADL) and quality of life (QOL) due to the onset and treatment of disease. In this study, we investigated whether there was an age-related difference in changes in health-related QOL indices after surgical resection of colorectal cancer (CRC).MethodsPatients who underwent elective surgery for primary CRC at our hospital between September 2017 and November 2021 were enrolled. Changes in QOL after surgery were evaluated after dividing the study population into a non-elderly (NE) group (younger than 75 years) and an elderly (E) group. A Short-Form 36-Item Health Survey was used as an index of QOL. The subscale and component summary scores before and 6 months after surgery were compared.ResultsForty-seven patients were included in the E group and 166 patients were the NE group. The E group had significantly worse preoperative performance and physical status than the NE group. However, indices of physical function were not worsened after surgery in either group. In the NE group, there were significant decreases in role physical and role component summary scores and significant increases in general health, mental health, and mental component summary scores. In the E group, there were no significant changes in the subscale or component summary scores after surgery.ConclusionOur study demonstrated elderly patient did not necessarily show a decline in QOL more than non-elderly patients after CRC surgery. Surgical resection for CRC should be considered even for elderly patients, while considering possible risk factors for worsening ADL and QOL.

Automated summary

This study investigated whether there was an age-related difference in changes in health-related quality of life (QOL) after surgical resection of colorectal cancer (CRC). The results showed that elderly patients did not necessarily show a decline in QOL more than non-elderly patients after surgery. There were significant improvements in QOL indices in the non-elderly group, while no significant changes were observed in the elderly group.
