Can anyone speak to the significance of perineural invasion in rectal cancer and long term prognosis 

  • Hi  

    I have been looking for some up to date information and I think most of the literature around does not specifically address this in a patient friendly way but more research papers . I have noticed this coming through a lot and will raise it with Macmillan to see if it can be addressed in their publications going forward .

    My limited understanding is it’s an independent predictive tool and part of the jigsaw pieces of information they use to decide the treatment pathway for a patient . That would also include lymph node involvement, tumour depth , cell type etc . 
    This gives them an idea of increased risks and the benefit of  chemotherapy. 
    In my limited  understanding being responsive to chemotherapy can change all of the above . I think my mum had every elevated risk plus a spread but incredibly responsive to Chemo. 
    So part of the decision making process but not in isolation and many variables also affect the long term survival like good surgical margins with curative intent and possible chemo for belts and braces approach .

    I think   might have had it and may know more . I have tagged her in and will speak to Macmillan team too .

    Take care ,

  • Hi,  , I had vascular invasion rather than yours, so can't directly help, but happy to talk if that helps? Mine indicated cells present in the veins around the removed bit. My guess is yours indicated them in the nerves, but whether this was in the bit removed or at the margins , it might be worth you asking your team. It may be that adjuvant chemo will be required. Again, ask your team. ((Hugs))

  • Hi Rd stage 3.

    I had extramural perineural invasion highlighted in histology from resection surgery for cancer in the sigmoid colon. You can read more on my user profile if interested.

    My understanding is that reporting on invasions has only become standard practice relatively recently so there is not heaps of data available.

    You are best asking your consultant regarding prognosis as it can depend on other factors such as other invasions and health conditions. It's also a conversation that is best dynamically held.

    Not everyone wants or is comfortable with knowing prognosis. I did ask for mine and I was grateful for the honest discussion. You cannot undo what you learn, so if you are in any doubt, don't rush your decision.

    I saw on your other post that you are N0 which is a very good aspect.

  • Would love to talk sometime
