Welcome to the forum . Immunotherapy is still not fully through yet in the UK and up till now has largely been through trials . However hoping that changes soon as it was going through the NICE committee I think !!
If you want to see the impact it is making you might like to look at American forums . They use Keytrunda as first line treatment for MSI patients but also doing some investigations on MSS patients who have a high tumour mutation load . You only have to google “ colon forums in America “ and I am sure they would pop up . They have some very encouraging results for some patients .
