Elderly Patient Outcomes in Colorectal Cancer Surgery

The management of colorectal cancer in patients aged 65 years and over poses unique challenges related to physiological reserve, the prevalence of coexisting conditions and the detection of frailty. Elderly patients often present with more advanced stage disease and higher rates of comorbidity, which influence both perioperative risk and long-term survival. Key determinants of outcome include optimisation of cardiovascular and pulmonary function, minimisation of surgical trauma through minimally invasive approaches and rigorous postoperative care pathways. Although 30-day mortality remains a standard metric, extended follow-up reveals that complications and excess mortality persist beyond this interval, particularly in the oldest age groups. Comprehensive preoperative assessment, tailored anaesthetic strategies and enhanced recovery protocols have together reduced length of stay and improved functional recovery. Nevertheless, postoperative complications such as anastomotic leak, respiratory failure and acute kidney injury remain more frequent in the elderly, underlining the need for targeted risk stratification and multidisciplinary perioperative management. Globally, research efforts now focus on integrating geriatric expertise into surgical pathways, refining risk models and validating metrics that accurately reflect the window of vulnerability in this population.

Elderly Patient Outcomes in Colorectal Cancer Surgery publication trend

The graph below shows the total number of articles in elderly patient outcomes in colorectal cancer surgery across all publications each year (not limited to Nature Index journals).

Technical terms

Comorbidity: The presence of one or more additional medical conditions co-occurring with a primary disease, often quantified by indices that predict surgical risk.

ASA grade: A classification by the American Society of Anesthesiologists that assesses preoperative physical status from I (healthy) to V (moribund), used to estimate perioperative risk.

Postoperative fatality window: The time interval following surgery during which mortality risk remains elevated above baseline, used to evaluate quality of care metrics.

Comprehensive Geriatric Assessment (CGA): A multidimensional evaluation of an older person’s health status, including functional, cognitive and social domains, guiding personalised care planning.
