abstract
Background: Given scarce data regarding the relationship among age, complications, and survival beyond the 30-day postoperative period for oncology patients in the United States, this study identified age-related differences in complications and the rate and cause of 1-year mortality following colon cancer surgery. Methods: The NY State Cancer Registry and Statewide Planning and Research Cooperative System identified stage I-III colon cancer resections ( 2004-2011). Multivariable logistic regression and survival analyses assessed the relationship among age ( <65, 65-74, >= 75), complications, 1-year survival, and cause of death. Results: Among 24 426 patients surviving 430 days, 1-year mortality was 8.5%. Older age groups had higher complication rates, and older age and complications were independently associated with 1-year mortality ( P < 0.0001). Increasing age was associated with a decrease in the proportion of deaths from colon cancer with a concomitant increase in the proportion of deaths from cardiovascular disease. Older age and sepsis were independently associated with higher risk of colon cancer-specific death (65-74: HR = 1.59, 95% CI = 1.26-2.00; >= 75: HR = 2.57, 95% CI = 2.09-3.16; sepsis: HR = 2.58, 95% CI = 2.13-3.11) and cardiovascular disease-specific death (65-74: HR = 3.72, 95% CI = 2.29-6.05; >= 75: HR = 7.02, 95% CI = 4.44-11.10; sepsis: HR = 2.33, 95% CI = 1.81-2.99). Conclusions: Older age and sepsis are associated with higher 1-year overall, cancer-specific, and cardiovascular-specific mortality, highlighting the importance of geriatric assessment, multidisciplinary care, and cardiovascular optimisation for older patients and those with infectious complications.
