Hi Everybody...so we have a copy of the oncology report following surgery and final staging was T3N2bM0 but EMVI and PNI positive.. mismatch repair proficient tumour..I think I know what EMVI positive means but not the other terms..isn't PNI peritoneal invasion..he never mentioned this in our meeting.its also a moderately differentiated tumour..I know I shouldn't have done but I've googled and have tied myself up in knots a bit.. the oncologist mentions successful resection with clear margins..can anybody help with some reassurance....
Hi ellen93. I’ve attached a link to the Macmillan page about staging
EMVI means the histology has detected some spread into blood vessels and PNI (perineural invasion) means there is some detected in the nerve or nerve sheath. Successful resection with clear margins is good news but you’ll probably have follow up chemo as the belt and braces.
Please don’t google! Ring your colorectal support nurse for a chat or the nurses on here on 0808 808 00 00 for reassurance
Take care

Kareno62 Thanks Karen..I have stopped googling..I'm not medically trained so I could so easily misinterpret something or the info is out of date..I am focusing on the fact they got it all out with clear margins and chemo will kill any nasties we can't see...
Hi ellen93, it's really positive that your husband had a successful resection and it is moderately differentiated (so not particularly aggressive).
I don't think there's ever a 'perfect' pathology report at stage 3 and 4 (stage 3 in your husbands case) tbh. The pathology report identifies risk factors to help guide treatment and monitoring post-surgery. You'll have some people who are EMVI and PNI negative but they have a really aggressive cancer, so it's all about knowing how to tackle follow up treatment for different tumour types.
The problem with Google is that it's so misleading. You'll read studies where they claim something is a negative prognostic marker...and then you see the study only involved about 40 ppl and had no statistical significance whatsoever.
