Background: Tumor budding has recently been recognized as one important prognostic factor for recurrence in patients with localized colon cancer. Nevertheless, not all guidelines consider tumor budding in the decision-making process for selecting patients for adjuvant chemotherapy. We aim to assess the prognostic value of tumor budding in a cohort of patients with stage II and III colon cancer. Methods: We included patients with pathologically confirmed diagnosis of stage II and III colon cancer at Hospital Universitario La Paz and tumor budding assessment available, from October 2016 to August 2021. Tumor budding was reported following the recommendations from the 2016 International Tumour Budding Consensus Conference. Results: A total of 390 patients were included. Patients were predominantly men (55%) and had a median age of 75 (35-95). Fifty percent of the patients were stage II and 50% were localized in the right colon. Tumor budding was reported as low, intermediate, and high in 186 (48%), 110 (28%), and 94 (24%) patients, respectively. After a median follow up of 18 months, 63 recurrences and 73 deaths were observed. Time to recurrence was significantly worse for patients with high tumor budding. At 24 months, 91%, 79%, and 67% of patients with low, intermediate and high budding were recurrence-free. Median TTR was not reached in any of the three cohort (P <0.001). Comparing high vs low or intermediate budding, the hazard ratio (HR) for recurrence was 0.13 [confidence interval (CI)95%: 0.05 to 0.32; P < 0.001]. We performed a univariate analysis with the most relevant clinic-pathological features. T4, N2, R1, bowel obstruction or perforation, positive resection margins (R1), lymphovascular or perineural invasion, and mismatch repair protein status were found to be statistically associated with TTR and entered the multivariate analysis. T4, N2, R1 and high tumor budding (HR: 0.48 [CI95%: 0.28 to 0.84], P = 0.011) were independent prognostic factors for recurrence at the multivariate analysis. Conclusions: High tumor budding is an adverse independent prognostic factor for recurrence in patients with stage II and III colon cancer and should be acknowledge when considering adjuvant chemotherapy.
