Recent advances in endoscopic diagnosis and treatment techniques have led to a marked increase in the detection and endoscopic treatment of early colorectal cancers ( CRC ). According to the J apanese S ociety for C ancer of the C olon and R ectum ( JSCCR ) guidelines, T1 ‐ CRC with a negative vertical margin, well‐ or moderately differentiated adenocarcinoma, no evidence of vascular or lymphatic invasion, and depth of invasion <1000 μm are considered to have a low risk of lymph node metastasis. However, T1 ‐ CRC with any of these risk factors are considered to have ahigh risk of lymph node metastasis. T1 ‐ CRC is considered to have a good prognosis if additional surgery is carried out. We experienced two cases of recurrence despite curative surgical resection of T1 rectal cancer.
