Correction to: Scientific Reports 10.1038/s41598-021-85572-0, published online 22 March 2021
The original version of this Article contained an error in the Materials and methods, under the subheading ‘Histopathological evaluation and treatment after endoscopic resection’,
“LVI was judged positive if vascular or lymphatic invasion was revealed in the MM or deeper layer. Droplet infiltration (DI) is a type of cancer invasion that is reported to be a risk factor for LNM26,27 and is determined by less than four cancer cells invading (apart from the main advanced part).”
now reads:
“LVI was judged positive if vascular or lymphatic invasion was revealed in the resected specimen. Droplet infiltration (DI) is a type of cancer invasion that is reported to be a risk factor for LNM26,27 and is determined by the invasion of clusters composed of four or fewer cancer cells.”
The original Article has been corrected.
