AimColorectal cancer (CRC) is prevalent in the older population, and surgery is the mainstay of curative treatment. A preoperative geriatric assessment (GA) can identify frail older patients at risk for developing postoperative complications. In this randomized controlled trial we wanted to investigate whether tailored interventions based on a preoperative GA could reduce the frequency of postoperative complications in frail patients operated on for CRC.MethodPatients > 65 years scheduled for elective CRC surgery and fulfilling predefined criteria for frailty were randomized to either a preoperative GA followed by a tailored intervention or care as usual. The primary end-point was Clavien-Dindo Grade II-V postoperative complications. Secondary end-points included complications of any grade, reoperation, length of stay, readmission and survival.ResultsOne hundred and twenty-two patients with a mean age of 78.6 years were randomized. We found no statistically significant differences between the intervention group and the control group for Grade II-V complications (68% vs 75%, P = 0.43), reoperation (19% vs 11%, P = 0.24), length of stay (8 days in both groups), readmission (16% vs 6%, P = 0.12) or 30-day survival (4% vs 5%, P = 0.79). Grade I-V complications occurred in 76% of patients in the intervention group compared with 87% in the control group (P = 0.10). In secondary analyses adjusting for prespecified prognostic factors, there was a statistically significant difference in favour of the intervention for reducing the total number of Grade I-V complications (P = 0.05).ConclusionA preoperative GA and tailored interventions did not reduce the rate of Grade II-V complications, reoperations, readmission or mortality in frail older patients electively operated on for CRC.Colorectal Disease © 2017 The Association of Coloproctology of Great Britain and Ireland.
