The relative five-year survival rate for patients diagnosed with lung cancer is 17.4 percent, as of 2015, according to the National Cancer Institute. The stage of cancer at initial diagnosis, the patient’s age and overall health, and individual response to treatment all affect treatment outcomes.
The earlier the lung cancer diagnosis, the greater the patient’s overall odds of surviving past the five-year mark, notes the National Cancer Institute. Patients diagnosed with localized cancer have a 54.8 percent five-year relative survival rate, while patients diagnosed with regional cancer with spread to regional lymph nodes have a 27.4 percent five-year relative survival rate. Patients diagnosed after the disease metastasizes to distant sites have a 4.2 percent relative survival rate.
