Factors Related to Frailty in Older Cancer Patients Undergoing Colorectal Surgery

BACKGROUND: Frailty is common in older cancer patients undergoing colorectal surgery, but few studies have focused on frailty and its associations in this population. OBJECTIVE: The aim of this study was to investigate the prevalence of frailty and its associations in older cancer patients undergoing colorectal surgery. METHODS: A convenience sample of 88 cancer patients 60 years or older undergoing colorectal surgery was recruited from 1 medical center. Frailty, physical activity, functional status, anxiety, depression, and social support of the patients were assessed before surgery, at discharge post surgery, and at 1 month post surgery. RESULTS: The prevalence of frailty in cancer patients undergoing colorectal surgery was 22.7% before surgery, decreased to 19.3% before discharge, and was 12.7% at 1 month after surgery. The proportion of prefrail patients significantly increased from 47.7% before surgery to 71.1% before discharge and was 64.6% at 1 month after surgery. Frail patients were more likely to be older and unmarried, have a lower albumin level, have lower physical activity, and be more dependent on others than nonfrail patients. CONCLUSION: Older cancer patients undergoing colorectal surgery were more likely to be prefrail after surgery than before surgery. Assessment of frailty and its associated factors is necessary for older cancer patients undergoing colorectal surgery before and after surgery. IMPLICATIONS FOR PRACTICE: Frailty may occur in cancer patients after colorectal surgery and is related to malnutrition and low physical activity. Appropriate discharge planning with physical activity tracking and an appropriate diet is encouraged to prevent frailty in cancer patients after colorectal surgery.
