In a study of real-world prospective data—GOSAFE—reported in the Journal of Clinical Oncology, Montroni et al found that the majority of patients aged ≥ 70 years undergoing colorectal cancer surgery showed maintained or improved quality of life and achieved functional recovery during follow-up.
The international study included consecutively enrolled patients aged ≥ 70 years at 26 hospitals worldwide. Quality of life was assessed with the EQ-5D-3L. Functional recovery was defined as the combination of an Activity of Daily Living score of ≥ 5, a Timed Up & Go test time of < 20 seconds, and a MiniCog score of > 2.
The study involved prospective data, collected between February 2017 and April 2019, for 625 (96.9%) of 646 consecutive patients. Among the 625 patients, 435 had colon cancer and 190 had rectal cancer. Median age was 79.0 years. Surgery was minimally invasive in 73% of all patients, including 74% of those with colon cancer and 71% of those with rectal cancer; palliative surgery was performed in only 5.5% of patients.
Equal or better quality of life was reported in 69.0% of patients (including 72.8% of those with colon cancer and 60.2% of those with rectal cancer) at 3 months after surgery, and in 70.3% of patients (including 72.9% of those with colon cancer and 63.9% with rectal cancer) at 6 months after surgery.
On multivariate analysis, a preoperative Flemish Triage Risk Screening Tool (fTRST) score of ≥ 2 was associated with poorer quality of life at 3 months (odds ratio [OR] = 1.68, P = .034) and 6 months (OR = 1.71, P = .027). Postoperative complications were associated with poorer quality of life at 3 months (OR = 2.03, P = .008) and 6 months (OR = 2.56, P = .02). Eastern Cooperative Oncology Group (ECOG) performance status of ≥ 2 was associated with poorer quality of life in the rectal cancer subgroup (OR = 3.81, P = .006).
Functional recovery was reported for 254 (78.6%) of 323 evaluable patients with colon cancer and 94 (70.6%) of 133 with rectal cancer. Factors associated with not achieving functional recovery included: age-adjusted Charlson Comorbidity Index of ≥ 7 (OR = 2.59, P = .009); ECOG performance score of ≥ 2 (OR = 3.12, P = .007, for colon cancer group; OR = 4.61, P = .009 for rectal cancer group); severe postoperative complications (OR = 17.33, P < .001); fTRST score of ≥ 2 (OR = 2.71, P = .003); and palliative surgery (OR = 4.11, P = .017).
The investigators concluded, “The majority of older patients experience good quality of life and [experience functional recovery] after colorectal cancer surgery. Predictors for failing to achieve these essential outcomes are now defined to guide patients’ and families’ preoperative counseling.”
They noted, “To our knowledge, the GOSAFE real-world prospective data show, for the first time, that major colon and rectal surgery in older patients with cancer results in restoration of a good quality of life 3 and 6 months after surgery in the majority of cases. This demonstrates, together with the patients’ ability to maintain their function in most cases … that older patients can undergo potentially curative … major cancer surgery without compromising an important priority: remaining independent.”
