55-year-old patient diagnosed with T3N1 rectal ADK. The lesion is located 2 cm from the anal verge and is 4 cm long, affecting the entire rectal wall, with signs of infiltration of mesorectal fat and internal sphincter. The patient is under neoadjuvant treatment. The control MRI finds disappearance of the lesion and adenopathies, showing only fibrosis and adenopathies of non-pathological size. A surgical macrobiopsy of the tumor is performed and is negative for malignancy. What would you do?
