- Objective: To investigate whether tumor deposits (TDs) in rectal cancer are associated withincreased recurrence risk and decreased survival.Summary background data: Tumor deposits (TDs) are considered a risk factor forrecurrence after colon cancer resection and presence of TDs prompts adjuvant chemotherapy.The prognostic relevance of TDs in rectal cancer requires further exploration.Methods: All patients treated with abdominal resection surgery for rectal cancer in Swedenbetween 2011 and 2014 were eligible for inclusion in this retrospective cohort-study based onprospectively collected data from the Swedish ColoRectal Cancer Registry. Primary endpointwas local recurrence or distant metastasis. Secondary outcomes were overall and relativesurvival.Results: 5455 patients were identified. 3769 patients were analysed after exclusion. TDs werefound in 404 (10.7%) patients including where 140 (3.7%) patients with had N1c-status. InTD-positive patients, local recurrence and distant metastasis rates at 5 years were 6.3% [95%CI 3.8-8.8%] and 38.9% [95% CI, 33.6-43.5%] compared to 2.7% [95% CI, 2.1-3.3%] and14.3% [95% CI, 13.1-15.5%] in TD-negative patients. In multivariable regression analysis,risk of local recurrence and distant metastasis were increased; HR 1.86 [95% CI, 1.09-3.19;P=0.024] and 1.87 [95% CI, 1.52-2.31; P=was 68.8% [95% CI, 64.4-73.4%] in TD-positive patients and 80.7% [95% CI, 79.4-82.1%] inTD-negative patients. pN1c-patients had similar outcomes regarding local recurrence, distantCopyright © 2022 Wolters Kluwer Health, Inc.

TD-positive pN1a-b patients hadsignificantly worse outcomes while TDs did not affect outcomes in pN2a-b patients.Conclusion: This study suggests that TDs have a negative impact on prognosis in rectalcancer. Thus, efforts should be made to diagnose TD-positive rectal cancer patientspreoperatively.
