Abstract
Colon cancer remains a leading cause of cancer-related deaths in the United States, with early detection critical for improved outcomes. Colonoscopy is a primary screening tool that can reduce incidence rates through the identification and removal of precancerous polyps. This study examines how undergoing a colonoscopy prior to diagnosis impacts two key surgical outcomes: tumor size and colon resection length. Data were collected from 70 de-identified patients who underwent colon resection for colon cancer between 2019 and 2024 at two regional hospitals in East Texas: Hunt Regional Medical Center and Mother Christus Frances Hospital. Using pathology reports, tumor size and resection length were compared between patients who had received a prior colonoscopy and those who had not. Statistical analysis, performed using the R Program, included Shapiro Wilks test and Mann Whitney U test to assess significance. Results indicate that patients with a history of a screening colonoscopy presented with significantly smaller tumors, suggesting less invasive surgical intervention. These findings support the effectiveness of colonoscopy as a tool not only for early detection but also for potentially reducing surgical burden. This data reinforce the value of colonoscopy as a preventative measure and highlight its role in improving both surgical outcomes and overall patient care.
