Pathological risk factors for lymph node metastasis in patients with submucosal invasive colorectal carcinoma

摘要

BackgroundRisk grade assessment determines therapy in patients with submucosal invasive colorectal carcinoma (CRC). However, treatment decisions are often difficult due to a lack of consensus on which risk factors should be considered. We aimed to identify predictive risk factors for lymph node metastasis (LNM) in a large cohort of submucosal invasive CRC patients from China.
