Prognostic value of lymph node metastasis in patients with T1-stage colorectal cancer from multiple centers in China

Abstract

The morbidity of T1-stage CRC was 3.17% for all CRC cases. Preoperative serum CA724, vascular invasion, and degree of differentiation are independent risk factors for lymph node metastasis. Lymph node metastasis is an independent prognostic factor for OS in patients with T1-stage CRC.
