Genomic Sequencing and Targeted Treatment..?

[Aviator2]

I've had 6 sessions of Flourouracil (5FU) and Irinotecan but the main cancer has slightly enlarged (Secondary in the lungs is the same).... I need some hope and wonder where I go from here. There are other treatments such as Virotherapy and Rigvir but only abroad, I think. Genomic sequencing is also of interest to me. Any advice would be welcome as this is all new to me.
