Introduction to Lung Cancer and Its Treatments
Lung cancer is a major health issue, impacting about 2.1 million people worldwide each year. It leads to roughly 1.7 million deaths annually. In the U.S. alone, 2023 saw about 240,000 new cases of lung cancer, with close to 130,000 deaths. Most people find out they have it when it’s already advanced. There are mainly two kinds: non-small cell lung cancer (NSCLC), making up 85-90% of cases, and small cell lung cancer (SCLC), which is about 10-15%.
The fight against cancer uses different methods like surgery, chemotherapy, and the newer immunotherapy. Surgery and radiation help most in early stages. But advanced stages usually need chemotherapy. This treatment uses drugs given through IV to attack cancer cells, yet it can cause tough side effects. Immunotherapy, which got its start in the U.S. in 2015 for certain lung cancer patients, works by boosting the body’s immune system to fight cancer. It has shown hope in raising some patients’ survival rates.
Screening for cancer early is key in finding it soon, which helps a lot with treatment success. New treatments, such as drugs targeting specific cancer cell mutations, are being used more and more. These include VEGF inhibitors and EGFR inhibitors. Thanks to these new options, doctors have better ways to fight lung cancer. Their goal? To help patients live longer, better lives while dealing with this tough disease.
Understanding Immunotherapy in Lung Cancer
Immunotherapy is a breakthrough in treating lung cancer. It uses our immune system to fight cancer cells. Unlike traditional therapies that attack fast-growing cells, immunotherapy boosts our immune system’s ability to spot and kill cancer cells. This gives us a stronger defense against lung cancer.
What is Immunotherapy?
Immunotherapy taps into the immune system’s power. It includes treatments like immune checkpoint inhibitors and therapeutic vaccines. One key strategy is to block proteins that stop immune activation. This lets T-cells attack cancer cells more effectively. Drugs that target PD-1 and CTLA-4 receptors play a big role in this, enhancing the immune fight against lung cancer.
How Does Immunotherapy Work for Lung Cancer?
For lung cancer, immunotherapy mainly uses immune checkpoint inhibitors. These drugs prevent cancer cells from hiding from the immune system. They stop the PD-L1 on cancer cells from connecting with PD-1 on T-cells. By also using CTLA-4 blockers, the immune system can better target tumors.
Some patients with certain mutations get treatments designed just for their cancer, like selpercatinib and sotorasib. The field of lung cancer immunotherapy is always advancing, with research aimed at finding more effective and personalized treatments.

Common Types of Lung Cancer
Lung cancer comes in different forms, affecting how patients are treated. It’s key to know the differences between non-small cell lung cancer and small cell lung cancer. This knowledge guides the creation of effective treatment plans. Each cancer type has unique traits and demands specific care plans.
Non-Small Cell Lung Cancer (NSCLC)
Non-small cell lung cancer is the most common type, making up about 85% of all cases. It includes different subtypes like adenocarcinoma and squamous cell carcinoma. NSCLC often spreads to other parts of the body, making treatment more challenging.
For NSCLC, there are several treatment options:
- Chemotherapy drugs include cisplatin, carboplatin, paclitaxel (Taxol), docetaxel (Taxotere), and vinorelbine (Navelbine).
- Immunotherapy options feature atezolizumab (Tecentriq).
- Targeted therapy utilizes drugs like bevacizumab (Avastin).
Researchers constantly look for biomarkers to help decide on treatments, improving how NSCLC is managed.
Small Cell Lung Cancer (SCLC)
Small cell lung cancer, though rarer, is very aggressive. It often gets found at a late stage. SCLC grows quickly and can spread early on. This makes fast diagnosis and treatment very important.
The usual treatments for SCLC include:
- Chemotherapy drugs such as cisplatin, carboplatin, etoposide, topotecan, and lurbinectedin (Zepzelca).
- Immunotherapy options comprise two approved drugs.
Finding the genes behind small cell lung cancer is tough, slowing down advances in targeted therapy. Studies aiming to find new treatments continue.
