Can the Endoscopic Features of Colorectal Carcinomas Predict Tumor Pathology and Stage?

Background and Aims: Our aim was to evaluate the demographic features of our colorectal cancer patients and assess the association between endoscopic and pathologic features in those patients. Materials and Methods: In this study, we retrospectively evaluated the medical records of patients who were diagnosed with colorectal cancer through biopsy taken by colonoscopy in the endoscopy unit of our hospital between January 2010 and October 2017. We analyzed endoscopic features of colorectal cancer such as luminal obstruction, macroscopic appearance, and histological features. Results: We obtained data from 168 patients for this study. The most common symptom was constipation and the most common cancer location was the sigmoid colon. Hematochezia was found to be significantly higher in cancers located in the left colon (p = 0.02). Symptoms, cancer location, and endoscopic obstruction were not significantly different between genders. Poor histological differentiation was significantly higher in the endoscopic obstruction group (p = 0.015). Conclusion: Immediate surgery and close follow-up in patients with endoscopic obstruction can impact their survival
