Hello there

 Can I kindly enquire about possible treatments options in addition to the standard pathway for stage 4  serous ovarian cancer/ solid tumours please? This was a missed/delayed diagnosis. I’ve been trying to research these treatments and I was wondering if anyone has any knowledge or experience of them at all, which seem to be available on the continent but apparently are not licenced here, although I have found previous clinical trials noting treatment success with these. Have tried to discuss with the oncologist who was not able to comment on them, and asked for a second opinion but been told there is no point currently as on the standard pathway of the 3 chemo agents. No one in the UK seems to be prepared to discuss this option. I’m sure there must be people out there who have either gone abroad to receive this treatment or potentially paid that company in order to have the treatment here. 
In addition, are there any current trials, potentially with a form of immunotherapy or other agent that might be suitable and eligible for at all please? 
Would so welcome any information or advice please. It feels like a minefield and there is already so much to have to deal with. 
Many thanks.
