Pedunculated Morphology of T1 Colorectal Tumors Associates With Reduced Risk of Adverse Outcome

There have been no large-scale studies to compare pedunculated vs non-pedunculated T1 colorectal tumors; risk stratification for adverse events, such as metastasis to lymph nodes, is based only on histologic features of tumors. We aimed to compare adverse outcomes of pedunculated vs non-pedunculated T1 colorectal cancers (CRC).
