    Background: Colorectal cancer is one of the most commonly diagnosed types of cancer worldwide. An early diagnosis and detection of colon cancer and polyp can reduce mortality and morbidity from colorectal cancer. Even though there are a variety of options in screening tests, the question remains on which test is the most effective for the early detection of colorectal cancer. In this prospective study, we aimed to develop a simple, useful, effective, and reliable scoring system to detect colon polyp and colorectal cancer. Methods: We enrolled 6508 subjects over the age of 18 from 16 centers, with colonoscopy screening. The age, smoking status, alcohol consumption, body mass index polyp incidence, polyp size, number and localization, and pathologic findings were recorded. Results: The age, male gender, obesity, smoking, and family history were found as independent risk factors for adenomatous polyp. We have developed a new scoring system which can be used for these factors. With a score of 4 or above, we found the following: sensitivity 81\%, specificity 40\%, positive predictive value 25.68\%, and negative predictive value 89.84\%, for adenomatous polyp detection

    AIM To investigate the effects of tumor localization on disease free survival (DFS) and overall survival (OS) in patients with stage I -III colon cancer. METHODS This retrospective study included 942 patients with stage. and. colon cancer, which were followed up in our clinics between 1995 and 2017. The tumors from the caecum to splenic flexure were defined as right colon cancer (RCC) and those from splenic flexure to the sigmoid colon as left colon cancer (LCC). RESULTS The median age of the patients was 58 years (range: 19-94 years). Male patients constituted 54.2\%. The rates of RCC and LCC were 48.4\% (n = 456) and 51.6\% (n = 486), respectively. During the median follow-up of 90 mo (range: 6-252 mo), 14.6\% of patients developed recurrence and 9.1\% of patients died. In patients with stage. and. disease with or without adjuvant therapy, DFS was similar in terms of primary tumor localization (stage.
