Abstract
BACKGROUND
Treatment of elderly patients with cancer is challenging as they can be overtreated with respect to frailty or undertreated because of advanced age. Maintaining a good quality of life is essential for this population. This study aimed to assess the difference in overall survival and short-term outcomes according to the extent of rectal cancer resection in patients aged ≥80 years.
METHODS
In this retrospective cohort study, very elderly patients with stage I-III rectal cancer aged ≥80 years were identified from the National Cancer Database (2004-2019). Patients were divided into 2 groups: radical resection and local excision. The groups were matched using exact matched analysis for clinical T and N stage, tumor size, and neoadjuvant treatment. The main outcome measures were overall survival, hospital stay, 30-day unplanned readmissions, and short-term mortality.
RESULTS
A total of 9634 patients were included (local excision = 2710; radical resection = 6924). After matching, 1106 patients were included in each group with a median follow-up of 49.9 and 51.7 months, respectively. The radical resection group had statistically significantly longer overall survival than did the local excision group (60 vs 57.2 months, P = .026). Local excision was associated with shorter length of stay (1 vs 7 days. P < .001), lower 30-day mortality (odds ratio: 0.43; 95% CI: 0.25-0.75, P = .003), lower 90-day mortality (odds ratio: 0.47, 95% CI: 0.32-0.68, P < .001), and lower 30-day readmission (odds ratio: 0.49, 95% CI: 0.33-0.74, P < .001). A subgroup analysis of matched patients with cTis-T2 and N0 tumors who underwent curative surgery revealed similar results.
CONCLUSION
Radical resection of rectal cancer in very elderly patients has a modest survival benefit, whereas local excision has lower odds of readmission and short-term mortality.
