Hi All

I am looking for any knowledge and advice from you all please.

I have a close friend who has recently been for a a colonoscopy which showed a polyp around 3cm. The polyp was removed and sent to histology which showed poorly differentiated adenocarcinoma. 

A subsequent pet scan has shown that it is spread to the mesorectal and pelvic side wall lymph nodes. 

They have been informed that it is probably the case that colon area will need to be removed and subsequent lymph nodes but one issue being is that the pelvic side walls are very difficult area and not many people will do this. However all research I have seen shows it’s reasonably common. 

Does anyone have experience or knowledge of this type of surgery? Any advice/specialist recommendations would be much appreciated. 

Thank you
