Abstract

Background: There is a growing interest in the adoption of formal prehabilitation programmes prior to elective surgery but regulatory targets mandate prompt treatment following cancer diagnosis. We aimed to investigate if time from diagnosis to surgery is linked to short- and long-term outcomes.

Methods: An exploratory analysis was performed utilising a dedicated, prospectively populated database. Inclusion criteria were biopsy-proven colorectal adenocarcinoma undergoing elective laparoscopic surgery with curative intent. Demographics, date of diagnosis and surgery was captured with patients dichotomised using 4-, 8- and 12-week time points. All patients were followed in a standardised pathway for 5 years. Overall survival was assessed with the Kaplan-Meier log-rank method.

Results: Six hundred sixty-eight consecutive patients met inclusion criteria. Mean time from diagnosis to surgery was 53 days (95% CI 48.3-57.8). Identified risk factors for longer time to surgery were males (OR 1.92 [1.2-3.1], p = 0.008), age ≤ 65 (OR 1.9 [1.2-3], p = 0.01), higher ASA scores (p = 0.01) stoma formation (OR 6.9 [4.1-11], p < 0.001) and neoadjuvant treatment (OR 5.06 [3.1-8.3], p < 0.001). There was no association between time to surgery and BMI (p = 0.36), conversion (16.3%, p = 0.5), length of stay (p = 0.33) and readmission or reoperation (p = 0.3). No differences in five-year survival were seen in those operated within 4, 8 and 12 weeks (p = 0.397, p = 0.962 and p = 0.611, respectively). Multivariate analysis showed time from diagnosis to surgery was not associated with five-year overall survival (HR 0.99, p = 0.52).

Conclusion: Time from colorectal cancer diagnosis to curative laparoscopic surgery did not impact on overall survival. This finding may allow preoperative pathway alteration without compromising safety.
