Depression and functional status in colorectal cancer patients awaiting surgery: Impact of a multimodal prehabilitation program.

OBJECTIVE

Depression and poor functional status (FS) frequently co-occur. Though both predict adverse surgical outcomes, research examining preoperative functional performance (FP; self-reported) and functional capacity (FC; performance-based) measures in depressed cancer patients is lacking. Prehabilitation, a preoperative intervention including exercise, nutrition, and stress-reduction, may improve FC; however, whether depressed patients benefit from this intervention remains unknown. The primary objectives were to (a) assess differences in FP and FC and (b) explore the impact of prehabilitation on FC in individuals with depressive symptoms versus those without.

METHOD

A secondary analysis was conducted on 172 colorectal cancer patients enrolled in three studies comparing prehabilitation with a control group (rehabilitation). Measures were collected at 4 weeks pre- and 8 weeks postoperatively. FP, FC, and psychological symptoms were assessed using the 36-Item Short Form Health Survey, Six-Minute Walk Distance (6MWD), and Hospital Anxiety and Depression Scale (HADS), respectively. Subjects were divided into three groups according to baseline psychological symptoms: no psychological-symptoms (HADS-N), anxiety-symptoms (HADS-A), or depressive-symptoms (HADS-D). Main objectives were tested using analyses of variance, chi-square tests, and multivariate logistic regression.

RESULTS

At baseline, HADS-D reported lower FP, had shorter 6MWD, and a greater proportion walked ≤ 400 m. Prehabilitation was associated with significant improvements in 6MWD in HADS-D group but not in HADS-N or HADS-A groups.

CONCLUSION

Poorer FS was observed in subjects with depressive symptoms, and these subjects benefited most from prehabilitation intervention. Future research could examine whether severity of depression and co-occurrence of anxiety differentially impact FS and whether prehabilitation can improve psychological symptoms and quality of life.
