Zusammenfassung:Background Colorectal cancer is the third most commonly diagnosed malignancy in Australia. Up to a third of patients who have undergone surgery with curative intent for colorectal cancer will have a recurrence of disease leading to significant morbidity and mortality. Regional Australians have disproportionately worse outcomes. Aim To identify factors associated with recurrence in colorectal cancer patients treated at a regional Australian hospital. Methods This study is a retrospective cohort analysis. Consecutive patients who have undergone curative resection at a regional public and private hospital by three surgeons from a single surgical practice for either rectal cancer or colon cancer were included. Prognostic indicators of recurrence were examined via both univariate and multivariate time‐to‐event analyses. Results Three hundred nine patients were included with 43 recurrences. Thirty presented with distant metastases, seven presented with locoregional recurrence and six presented with locoregional as well as distant recurrence. In univariable analysis, higher rates of recurrence were associated with tumour type, higher AJCC summary stage, higher preoperative levels of CA19‐9, perineural invasion, lymphovascular invasion,
