To put on my best British accent "complete rubbish".

The UK runs world-class trials in adoptive cell transfer and other cell based therapies for cancer. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4442586/

I surmise it was the radiation, chemotherapy, and surgery that contributed most to a 5+ year survival and no evidence of disease. This is available worldwide. Adoptive cell transfer has a complete response rate of 10-30% in unselected patients.

By far the most important recent advance in metastatic colon cancer is PDL1 directed immunotherapy for microsattelite instable colon cancer. This is also readily available in the UK
