Background: The prognostic value of tumor regression grade (TRG) after neoadjuvant chemoradiotherapy for rectal cancer is inconsistent in the literature. Both TRG and post-therapy lymph node (ypN) status could reflect the efficacy of neoadjuvant therapy. Here, we explored whether TRG combined with ypN status could be a prognostic factor for MRI-based lymph node-positive (cN+) rectal cancer following neoadjuvant chemoradiotherapy.

Background/aims: Inaccurate prediction of lymph node metastasis (LNM) may lead to unnecessary surgery following endoscopic resection of T1 colorectal cancer (CRC). We aimed to validate the usefulness of artificial intelligence (AI) models for predicting LNM in patients with T1 CRC.
Methods: We analyzed the clinical data, laboratory results, pathological reports, and endoscopic findings of patients who underwent radical surgery for T1 CRC.

Inhibin, β, which is also known as INHBA, encodes a protein that belongs to the Transforming Growth factor-β (TGF-β) superfamily, which plays a pivotal role in cancer. Gastrointestinal tract (GI tract) cancer refers to the cancers that develop in the colon, liver, esophagus, stomach, rectum, pancreas, and bile ducts of the digestive system.
