[A Case of Recurrent Ascending Colon Cancer with Concomitant Dementia Successfully Treated with Chemotherapy].

A 72-year-old man with advanced dementia presented with a right lower abdominal painful mass, and on detailed examination and investigation, was diagnosed to have moderately differentiated circumferential tubular adenocarcinoma infiltrating the abdominal wall in the middle of the ascendingcolon. It was extremely painful, and there was also a risk of ileus if left untreated. Therefore, laparoscopic right hemicolectomy was performed. One year after surgery, examination revealed local recurrence. After consultation with family members, we started with chemotherapy, usingcapecitabine and bevacizumab. It is our policy to administer chemotherapy under adequate surveillance. Thus, outpatient chemotherapy was safely administered in a dementia patient with shrinkage of local recurrent lesions.
