Open AccessIntegrative modeling of tumor genomes and epigenomes for enhanced cancer diagnosis by cell-free DNA
Multi-cancer early detection remains a key challenge in cell-free DNA (cfDNA)-based liquid biopsy. Here, we perform cfDNA whole-genome sequencing to generate two test datasets covering 2125 patient samples of ...

Open AccessClinical outcomes of colonoscopic polypectomy with strategic surveillance colonoscopies in patients with 10 or more polyps
The clinical usefulness of repeat colonoscopic polypectomy in patients with numerous polyps has not been sufficiently determined. We aimed to analyze the clinical outcomes of colonoscopic polypectomy with surv...

Open AccessAnchoring the snare tip is a feasible endoscopic mucosal resection method for small rectal neuroendocrine tumors
Small rectal neuroendocrine tumors (NETs) can be treated using cap-assisted endoscopic mucosal resection (EMR-C), which requires additional effort to apply a dedicated cap and snare. We aimed to evaluate the f...

Open AccessMachine learning approach for differentiating cytomegalovirus esophagitis from herpes simplex virus esophagitis
The endoscopic features between herpes simplex virus (HSV) and cytomegalovirus (CMV) esophagitis overlap significantly, and hence the differential diagnosis between HSV and CMV esophagitis is sometimes difficu...

Open AccessRisk of postpolypectomy bleeding in patients taking direct oral anticoagulants or clopidogrel
The usage of direct oral anticoagulants (DOACs) to prevent and treat thromboembolic events is gradually increasing. We aimed to evaluate the outcomes of patients taking DOACs after polypectomy. We retrospectiv...

Open AccessReal-time detection of colon polyps during colonoscopy using deep learning: systematic validation with four independent datasets
We developed and validated a deep-learning algorithm for polyp detection. We used a YOLOv2 to develop the algorithm for automatic polyp detection on 8,075 images (503 polyps). We validated the algorithm using ...
