Separate and distinct from others of the same kind; treated individually.
Case-by-case implies that each treatment is different and is not generalisable; but the fact that they use a patient’s own tissue does not make each individual treatment different. If you want to extend the logic, you might call vaccination a case-by-case treatment as well, since they use different needles for each person.
The approach is generic. The implementation is case by case. But this is exactly the problem. When the implementation is generic, like a vaccine, then you can mass produce it and the costs go down.
As far as this seems, you can’t mass produce this solution. You can mass implement the approach, but that doesn’t really bring the cost down.
Because you can’t pack it up in a box and ship it to just anyone. They have to make it specifically for you. Hence case-by-case.
That’s not what case-by-case means. Wiktionary:
