Introduction: The aim of this study was to assess the surgical management and overall survival of patients with residual foci of malignancy and/or adverse histopathological features post polypectomy where major resection is undertaken as definitive treatment. Methods: An analysis was conducted of a prospectively collected, clinician-led colorectal cancer database of private and public patients in Victoria, Australia from 2010-2017. Patient characteristics, surgical detail and histological outcomes together with patient follow-up were examined. Results: A total of 176 treatment episodes were analyzed in the study period; age range was 22-88 years and 48% male. Preoperative CEA was performed in 47% of cases, range 0.2-41.3 μg/L. Follow-up was available in 86.4% of cases and ranged from 21 days to 6.7 years. Median lymph node harvest was 14 with malignant lymph nodes (including a mesenteric tumor deposit) detected in 14 patients (8%). Surgical entry included 8 robotic cases and 1 transanal total mesorectal excision. Follow-up data revealed 137 alive no recurrence, 6 alive with disease, 1 alive with second primary cancer and 7 deceased (other causes). Metastatic disease developed in 8 patients (4.5%), detection date range 0.7-4.7 years. Conclusion: The appropriate management of residual disease and/or adverse histopathological features post colonoscopic polypectomy is challenging in many cases and concerns of ‘over-treatment’ are often raised. Our study revealed that malignant nodes were harvested in 8% of patients and may guide clinicians and patients in their choice of treatment.
