CRISPR cancer trial success paves the way for personalized treatments
MD and I work in the field. The technology is called CAR-T, as the article mentioned. It’s been used pretty widely for “liquid” tumors for a while (eg leukemia, lymphoma, and multiple myeloma),but solid tumors are particularly difficult to target using current CAR-T therapy. If this CRISPR  tech can be applied widespread to solid tumors that opens up a huge swath of patients that can be treated.However cost and logistics are a huge factor. CAR-T therapy currently cost about $300,000-$500,000 to treat a patient. Beyond the cost of the immunotherapy you require a huge institutional investment because there are characteristic side effects that occur within the first 30 days of treatment which necessitates patients to be either admitted to the hospital for 30 days or stay in close proximity with daily check-ins (yes the cancer is getting treated BUT now your immune system is hyperactive which can be very dangerous in the short term).Very few academic hospitals, let alone community hospitals, have this bandwidth which will lead to cancer care being concentrated in a handful of a few very large cancer specific institutions.
