Stage III lung cancer is a serious condition where the cancer has spread to nearby tissues or lymph nodes but not to distant parts of the body. At this stage, the disease is considered advanced, but it is still potentially treatable with a combination of therapies. Many patients ask, “What is the best treatment for stage III lung cancer?” The answer depends on the type of lung cancer, the patient’s overall health, and whether the cancer is operable.
Understanding Stage III Lung Cancer
Lung cancer is divided into non–small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). About 85% of lung cancers are NSCLC, and stage III is further divided into IIIA, IIIB, and IIIC, depending on how far the cancer has spread within the chest.
At this stage, treatment usually involves a multimodal approach, meaning doctors often combine several therapies to achieve the best outcome.
Common Treatments for Stage III Lung Cancer
Chemotherapy and Radiation Therapy
The most common treatment for stage III lung cancer is a combination of chemotherapy and radiation therapy.
- Chemotherapy uses powerful drugs to kill cancer cells throughout the body.
- Radiation therapy targets the tumor and nearby lymph nodes with high-energy rays.
When used together, this combination is called concurrent chemoradiation, and it has been shown to improve survival rates compared to using either treatment alone.
Surgery (For Select Patients)
Not all stage III lung cancer patients are candidates for surgery, but in certain cases—especially stage IIIA—surgery may be an option after chemotherapy or radiation has reduced the tumor. Surgeons may remove part of the lung (lobectomy) or the entire lung (pneumonectomy) if necessary.
Surgery is often followed by additional chemotherapy or radiation to reduce the risk of recurrence.

Immunotherapy
In recent years, immunotherapy has become an important breakthrough in treating stage III lung cancer. Drugs such as PD-1 or PD-L1 inhibitors help the immune system recognize and attack cancer cells.
For patients who have completed chemoradiation, the immunotherapy drug durvalumab is often prescribed as maintenance therapy. Studies show it significantly improves survival in stage III NSCLC.
Targeted Therapy
If the cancer cells have certain genetic mutations (such as EGFR, ALK, or ROS1), doctors may recommend targeted therapy. These drugs block specific changes in cancer cells that allow them to grow. Targeted therapy is usually given in pill form and can be highly effective for patients with the right biomarkers.
Factors That Influence Treatment Choice
The best treatment plan for stage III lung cancer depends on several factors:
- The exact stage (IIIA, IIIB, or IIIC)
- Whether the cancer is operable
- The type of lung cancer (NSCLC vs. SCLC)
- The patient’s overall health and ability to tolerate treatment
- Genetic and molecular testing results
Because every patient is different, treatment decisions are usually made by a multidisciplinary team of doctors, including oncologists, thoracic surgeons, and radiation specialists.
The best treatment for stage III lung cancer is often a combination of therapies, including chemotherapy, radiation, surgery (in select cases), immunotherapy, and targeted drugs. With advances in modern medicine, patients now have more options and improved survival rates compared to the past.
If you or a loved one has been diagnosed with stage III lung cancer, talk to your healthcare provider about the latest treatment options and whether clinical trials might be available. Early and personalized treatment planning gives the best chance of managing the disease effectively.
