For more than three decades, care for small-cell lung cancer (SCLC) remained mostly the same. That’s changing now — doctors have a new option called immunotherapy. This line of treatment uses your body’s own immune system to fight cancer. What Is Immunotherapy? The immune system is your body’s defense against harmful substances. It attacks foreign particles, like germs and viruses. But cancer can confuse your body. As cells change and grow out of control, your immune system may not think of them as a threat. Scientists have developed drugs to help your immune system target and destroy cancerous cells. They include: Immune checkpoint inhibitors. Some immune cells have proteins that act as off switches. These ‘checkpoints’ prevent them from killing cancer cells. Immune checkpoint inhibitors target these proteins and allow immune cells to attack the cancer. Cancer vaccines. These substances kick-start an immune system response. They can prevent or treat certain cancers. Scientists are beginning to study vaccines for SCLC. Which Drugs Treat SCLC? There are several FDA-approved immunotherapy drugs for SCLC, including: Atezolizumab (Tecentriq) and Durvalumab (Imfinzi). You might take these immune checkpoint inhibitors alongside chemotherapy. Nivolumab (Opdivo) and Pembrolizumab (Keytruda). You might take these immune checkpoint inhibitors if your cancer doesn’t respond or returns after treatment with a certain chemotherapy. Tarlatamab (Imdelltra). This is a newer type of immunotherapy called a bispecific T-cell engager (BiTE). It acts like a matchmaker. One end of the medicine attaches to a cancer cell, while the other end grabs a T cell (a powerful part of your immune system). By pulling them together, the medicine forces your immune system to see and destroy the cancer. When Do You Get Immunotherapy? Depending on how much your cancer has spread, your cancer doctor will usually recommend treatment with surgery, chemotherapy, or radiation. But SCLC is an aggressive disease that grows quickly. It often becomes resistant to the chemotherapy drugs. Most of the time, the cancer returns. That’s when it’s time to try immunotherapy. Because scientists are still studying the drugs, doctors are careful about when to prescribe them. They can cause serious side effects, like inflammation of the organs. Your doctor will weigh the pros and cons. Most people get immunotherapy after two or more rounds of chemotherapy. How Do You Get the Treatment? You go to your doctor’s office, a clinic, or the outpatient unit of a hospital. An IV will deliver the immunotherapy into your vein. The process usually takes around an hour. Depending on the drug, you’ll receive treatment every few weeks. Your doctor will decide how long you’ll get this medication. Usually, the goal is to prevent the cancer from getting worse instead of curing the disease.
