The SEER database tracks 5-year relative survival rates for non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) in the United States, based on how far the cancer has spread. The SEER database, however, does not group cancers by AJCC TNM stages (stage 1, stage 2, stage 3, etc.). Instead, it groups cancers into localized ...

Apr 30, 2024 · The stages of lung cancer range from 1 to 4. The lowest number means that the cancer is small and only in the lung. As the cancer grows larger or spreads outside of the lungs, the numbers get higher. A stage 4 lung cancer has spread to other areas of the body. In small cell lung cancer, the stages may be called limited or extensive.
Jun 4, 2023 · The variability in survival rates highlights one key reality about stage 4 lung cancer: No two people have the same disease. Arguably more than any other stage of the disease, stage 4 lung cancer survival is influenced by multiple factors. Some of these are fixed (non-modifiable) and others can be changed (modifiable).
Nov 4, 2023 · These survival rates for the most advanced lung cancer stages are estimated using a slightly different benchmark. The 2- and 5-year survival rates for all types of lung cancer are: Stage IVA: 23%; 10%
Oct 4, 2023 · Stage 0: Also called “in situ," this stage means that cancer cells are only found in the top lining of the lung or bronchus and have not spread.; Stage I: Tumors are small and found in only one lung. Cancer has not spread to any lymph nodes or other areas of the body. Stage I is divided into substages IA and IB, based on the size of the tumor.
May 5, 2023 · Prognosis. The overall 5-year survival rate for stage 4 non-small cell lung cancer is approximately only 4% but can be much higher in certain populations. The median survival time (time at which 50% of patients are alive and 50% have died) is about eight months. Understanding Lung Cancer Survival Rates.
Stage 4 is part of the number staging system. It uses the TNM system to divide cancers into stages. There are 4 stages of lung cancer, numbered from 1 to 4. Stage 4 can be divided into 4A and 4B. Stage 4 non small cell lung cancer is also called metastatic (advanced) lung cancer. Stage 4A. There are 2 possible stages for stage 4A:
