Reviewer's report:
The authors present an interesting and rare case of multiple colonic metastases
from a locally advanced primary rectal cancer. The case is very unusual and
would be of interest to the readership. 
It is important to confirm that there is no inherited polyposis syndrome present in
this patient. I assume the patient had a diagnostic colonoscopy so it would be
important to report that there were no colonic deposits or polypoid deposits
present at diagnosis. Was any immunohistochemistry undertaken on the tumour -
were there any unusual molecular features such as MSI high. Please add this to
