Stage IV Non-Small Cell Lung Cancer
Stage IV non-small cell lung cancer (NSCLC) is the most advanced form of the disease. In stage IV, the cancer has metastasized, or spread, beyond the lungs into other areas of the body. About 40 percent of NSCLC patients are diagnosed with lung cancer when they are in stage IV. The five-year survival rate for those diagnosed with stage IV lung cancer is less than 10 percent.
There are numerous treatment options available for patients with advanced-stage disease at Cancer Treatment Centers of America (CTCA). We also provide therapies to ease the symptoms that can be associated with NSCLC, while improving your quality of life.
TNM categories of stage IV
Stage IV lung cancer can be any T or N, meaning that the tumor can be any size and may or may not have grown into the nearby lymph nodes. The cancer can be categorized as either M1A or M1B. For M1A, any of the following will be true:
- The cancer has spread to the other lung.
- Cancer cells are located in the fluid surrounding the lungs (malignant pleural effusion).
- Cancer cells are located in the fluid surrounding the heart (malignant pericardial effusion).
M1B stage IV lung cancer means that the cancer has spread to distant lymph nodes or to other organs such as the bones, liver, adrenal gland, kidneys or brain.
Common treatments for stage IV non-small cell lung cancer: In stage IV lung cancer, chemotherapy is often the recommended course of treatment. Immunotherapies may also be recommended as a secondary approach.
