Key result
Colorectal surgery is linked to ~44% five-year survival in low-risk nonagenarians compared to no surgery.
Why the study?
The short-term and long-term outcomes of nonagenarians treated for colorectal cancer were not well characterized.

Supports selective surgery in fit nonagenarians with colorectal cancer; leaves open need for prospective validation before broader adoption.
Cohort (n=74)
Does colorectal surgery improve survival in nonagenarians with colorectal cancer compared to no surgery?
Colorectal surgery can be performed with acceptable mortality in nonagenarians with low perioperative risk, offering improved survival compared to non-surgical management.
Arenal et al. (2011) conducted a cohort in colorectal cancer (n=74). Colorectal surgery vs. No surgery was evaluated on Mortality, morbidity and survival. Colorectal surgery in nonagenarians with low perioperative risk yielded 5% surgical mortality and 44% 5-year survival, whereas no non-surgical patients survived beyond 36 months.
