Five-year survival rates for stage IA and IB non-small cell lung cancers are 49 and 45 percent, respectively, according to the American Cancer Society. Factors influencing survival rates include the patient’s overall general health, age and type of treatment chosen.
The rates published in 2015 are compiled using data obtained from lung cancer diagnoses made between the years 1998 and 2000, explains the American Cancer Society. Researchers used data from the National Cancer Institute’s database to calculate the rates in 2007, and advances in oncological treatment since that time may influence and improve the chances of survival of patients with stage I lung cancers.
Surgery is the general course of treatment for stage I lung cancers, states the American Cancer Society. For many stage I lung cancer patients, surgery is the sole treatment necessary to kill off the cancer. Removal of the affected lobe or section of the lung, usually along with some lymph nodes from the surrounding area that was biopsied to look for traces of cancer, is the extent of stage I treatment.
A patient with stage I lung cancer may need to have chemotherapy after surgery depending on the size of the tumor, its location and other factors, notes the American Cancer Society. This may reduce the risk of cancer recurrence.
