Background: Early anal canal cancer is frequently treated with endoscopic submucosal dissection (ESD) to preserve anal function. However, if the lesion is in the anal canal, then significant difficulties such as bleeding and challenges associated with scope manipulation can arise.
Case Summary: A 70-year-old woman undergoing follow-up after transverse colon cancer surgery was diagnosed with anal canal cancer extending to the dentate line.
Background: Recent studies have focused on evaluating the biomarker value of textural features in radiological images. Our study investigated whether or not a texture analysis of computed tomographic colonography (CTC) images could be a novel biomarker for colorectal cancer (CRC).
Methods: This retrospective study investigated 263 patients with CRC who underwent contrast-enhanced CTC (CE-CTC) before curative surgery between January 2014 and December 2017.
Objective: Gingival recession is a complication that can occur after orthodontic treatment, and its cause is still very controversial in the literature. The objective of this study was to report a clinical case of orthodontic retreatment conducted with in-office aligners and root coverage using free gingival graft, connective tissue graft, and Emdogaim for a patient with severe gingival recession.
Clinical Considerations: This report presents a potential solution to correct a gingival recession with in-office clear aligner.
Background/aim: Although the impact of body composition on cancer treatment outcomes of patients with cancer has been increasingly reported, it is still unclear whether the radiodensity of subcutaneous adipose tissue (SAT) on computed tomography (CT) images has a prognostic impact on patients with gastric cancer. We measured muscle and SAT profiles on CT and performed an integrated analysis with clinicopathologic factors.
Patients And Methods: We retrospectively analyzed 230 patients with gastric cancer who underwent gastrectomy between June 2016 and December 2020.
