T1 colorectal cancer management in the era of minimally invasive endoscopic resection

Table 3 T1 Colorectal cancer post-resection algorithm

	High-risk T1 CRC	Low-risk T1 CRC
High Risk Histopathology Features (lymphovascular invasion, tumor budding, poor differentiation, deep submucosal invasion (≥ 1000 µm)1, positive resection margin)	Presence of one or more histopathology features	Absence of all high-risk histopathology features
Resection status	Non-curative	Curative
Recommended management	Adjuvant surgery or multidisciplinary review	Surveillance

¹Deep submucosal invasion may be considered a low-risk feature in isolation.
