Chen TC, et al. - The clinical outcomes of patients with primary colorectal cancer ≥ 90 years old were examined via retrospectively reviewing the medical records of 100 of these patients with primary colorectal adenocarcinoma. Patients who had tumor resections vs those who had non-operative treatments displayed longer overall and cancer-specific survival. Researchers identified age, body mass index, performance status, advanced cancer stage (stages 3 and 4), and treatment strategy as risk factors, prognostic factors, and predictors of overall survival. Outcomes thereby suggest not denying surgical treatment to these patients in clinical practice. However, the in-hospital mortality rate was 6.25% in patients who had elective open surgeries and 42.9% in those who had emergent open surgeries, so these mortality rates may be a deterrent.
