Clinical Characteristics and Pathological Features of "Crawling-type" Early Gastric Carcinoma: A Retrospective Series of Eight Cases.

Background: "Crawling-type" early gastric carcinoma (EGC) is a rare subtype of gastric cancer (GC) that is challenging to diagnose at an early stage due to its low-grade nuclear heterogeneity and morphology that mimics intestinal metaplasia. This study aimed to explore the clinical characteristics and pathological features of patients with crawling-type EGC.

Methods: This case series study retrospectively included patients with crawling-type EGC who underwent endoscopic submucosal dissection (ESD) or gastrectomy at the East Hospital Affiliated to Tongji University between January 2019 and March 2022.

Sessile Serrated Lesions: Searching for the True Prevalence and Risk Factors in China.

Background/aims: Growing recognition identifies sessile serrated lesions (SSL) as colorectal cancer (CRC) precursors. However, the SSL detection rate remains debatable and lacks a definitive consensus. Additionally, understanding the influencing factors in SSL development is limited.
