Small Cell: Extensive Stage
In extensive small cell lung cancer, the cancer that originated on one side of the lung has either gone to both or spread to the body. Here it can’t be curative and it’s extensive or stage four. We still use the same drugs with carboplatin or cisplatin, usually carboplatin because it’s a little more tolerable as well as etoposide. But now we also use immune therapy with it. And that’s because the studies show that using immune therapy with your cytotoxic chemotherapies actually greatly improves progression-free and overall survival. When you do those cytotoxic chemo cycles, about four cycles, then you just do the immune therapy to maintain your remission or your response.
