These findings were independent of the presence of ulceration for lesions less than 3cm and of the size of the tumor when there was no ulceration. The same happened with well or moderately well differentiated tumors less than 3cm with minimal submucosal invasion and without lymphovascular compromise. These findings are currently a source of controversy.
Estos hallazgos fueron independientes de la presencia de ulceración para lesiones menores de 3 cm y de la talla del tumor si no existía ulceración; igualmente, sucedió con los tumores bien o moderadamente diferenciados menores de 3 cm con mínima invasión a la submucosa y sin compromiso linfovascular.
