Chimeric antigen receptor T-cell (CAR-T) therapies are a very promising form of cancer immunotherapy. Initially developed for use against blood cancers, they are now showing their worth in the treatment of solid tumors. The most important aspect of this technology platform is not that it is effective, but rather that it can be adapted at an incremental cost to many types of cancer. The future of cancer treatment is entirely determined by choice of strategy: without a broadly applicable therapy with a low cost of adaptation, or ideally a universal therapy that can be applied as-is to any cancer, then there are too few researchers and far, far too many different types of cancer for the progress we’d like to see. If we wish to see cancer controlled in our lifetimes, then the development of general therapies that can be applied to most or all types of cancer is a requirement.
Immunotherapy has given patients and oncologists new options, which for some patients, has meant cures for diseases that had been untreatable. Colorectal cancer has a high mortality rate in advanced stages of the disease with few
