Background: The purpose of this study was to compare outcomes and adverse events between three-dimensional conformal radiation therapy (3D-CRT) and intensity-modulated radiation therapy (IMRT) in patients undergoing long-course neoadjuvant radiation therapy (NA-RT) for locally advanced rectal adenocarcinoma (LARC).
Methods: We retrospectively analyzed a total of 47 consecutive patients who received NA-RT for LARC between January 2011 and September 2022. Seven and 40 patients were diagnosed with clinical stages II and III, respectively.
Background: Ulcerative colitis (UC) causes extensive ulceration attributable to intestinal inflammation. This study investigated the effect of past extensive ulcers (PEUs) on fecal calprotectin (FC).
Methods: This retrospective, single-center, observational study included patients with UC with a Mayo endoscopic subscore of 0.
