Stomach cancer stage 4 Folfox Nivolumab

As far as I am aware they just the CT scan i don't know about markers etc  

Hi Jessica

i was just wondering where your mum was being treated? My dad is at the beginning of his cancer journey, starting FOLFOX once he has a stent put in. My hopes are that he responds well enough to the chemo that we can potentially do a partial gastronomy and HIPEC but those are just my aspirations. Having spoken to the oncologist, it seems like the NHS will unlikely be offering any type of surgery and will be monitoring my dad instead. This of course is not good enough for me and so I started researching what was out there and indeed found conversion surgery with HIPEC significantly increased the survival rate.
