MANAGEMENT OF ENDOSCOPICALLY RESECTED PT1 COLORECTAL CANCER. SURGERY OR FOLLOW UP? SINGLE CENTER EXPERIENCE, LONG TERM FOLLOW UP AND COST ANALYSIS

The spread of colorectal cancer (CRC) screening programs and the improvement of endoscopic techniques are incrementing the number of endoscopically treated pT1 CRC. The menace of lymphnode metastasis in presence of histopathological risk factors often requires additional surgery, but despite many guidelines, correct management remains variable and unclear. Our aim was to evaluate factors influencing therapeutic decision-making in endoscopically resected pT1 CRCs in a tertiary referral center, and analyze costs of different approaches.
