(2) Methods: Patients with tumors located in the rectosigmoid colon, sigmoid colon, and rectum who were operated on were included. Upon admission, we examined the patients\u2019 first diagnostic colonoscopies and their preoperative repeat control colonoscopies and computed tomography (CT) report. (3) Results: In this study, 23 patients (57.5%) were male. The overall accuracy rates were 80.0% (32\/40) in colonoscopy, 65.0% (26\/40) in preoperative CT, and 87.5% (35\/40) in retro CT, and the differences among the examination methods were statistically significant (p = 0.049). The sensitivity levels decreased to 50.0% for colonoscopy and preoperative CT and 75.0% for retro CT in rectosigmoid colon tumors. In rectal tumors, the sensitivity levels were 75.0% in colonoscopy, 60.0% in preoperative CT, and 80.0% in retro CT. In two patients, the tumor location was given incorrectly, and postoperative pathological evaluations indicated T3N0 tumors; the initially planned treatment was thus changed to include radiotherapy in addition to chemotherapy in the postoperative period because the tumor was located in the middle rectum. (4) Conclusions: Accuracy in tumor localization in sigmoid, rectosigmoid, and rectum tumors still needs to be improved, which could be accomplished with prospective studies. CT evaluations for cancer localization in this patient group should be re-evaluated by a radiologist.<\/jats:p>","DOI":"10.3390\/diagnostics14131363","type":"journal-article","created":{"date-parts":[[2024,6,27]],"date-time":"2024-06-27T04:19:26Z","timestamp":1719461966000},"page":"1363","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Diagnostic Benefits and Surgical Implications of Methods for Tumor Localization in Sigmoid and Rectum Tumors"],"prefix":"10.3390","volume":"14","author":[{"given":"Mehmet Onur","family":"Gul","sequence":"first","affiliation":[{"name":"Surgical Oncology Clinic, Malatya Training Research Hospital, 44000 Malatya, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0232-1284","authenticated-orcid":false,"given":"Mehmet","family":"Akcicek","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Department of Radiology, Malatya Turgut \u00d6zal University, 44000 Malatya, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7727-602X","authenticated-orcid":false,"given":"Nidal","family":"Iflazoglu","sequence":"additional","affiliation":[{"name":"Surgical Oncology Clinic, Bursa City Hospital, 16110 Bursa, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7616-4798","authenticated-orcid":false,"given":"Kadir","family":"Corbaci","sequence":"additional","affiliation":[{"name":"General Surgery, Osmaneli Mustafa Selahattin \u00c7etinta\u015f State Hospital, 11500 Bilecik, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cuma Ali","family":"Emir","sequence":"additional","affiliation":[{"name":"Surgical Oncology Clinic, Malatya Training Research Hospital, 44000 Malatya, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mehmet","family":"Guzel","sequence":"additional","affiliation":[{"name":"Gastroenterology Surgery, Malatya Training Research Hospital, 44000 Malatya, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cem Kaan","family":"Parsak","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Department of Surgical Oncology, Cukurova University, 01330 Adana, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"209","DOI":"10.3322\/caac.21660","article-title":"Global cancer statistics 2020: GLOBOCAN estimates of incidence and mortality worldwide for 36 cancers in 185 countries","volume":"71","author":"Sung","year":"2021","journal-title":"CA A Cancer J.
