It's been available for about a decade at this point. Why bother? That's a good question. I think the answer is "because 5% will be cured and another 20% will have some response which means they may live another few years." But the problem is, you won't know who benefits and who doesn't. So do you deny everyone a chance at a 5% cure of 20% chance of a longer life? No, you treat everyone and see what happens. The UK government put a price of ~25,000GBP per year of life (quality adjusted). So even if people are cured there is value in extending years of life.
