Staging of lung cancer

Prognostic factors


The most important prognostic factor in lung cancer is the stage of disease.

Performance status & weight loss

  • Patients who are ambulatory have a significantly longer survival than those who are nonambulatory.

  • Patients who have lost > 5% of body weight during the preceding 3-6 months have a worse prognosis

Molecular prognostic factors

Several studies have indicated that mutations of the K-ras proto-oncogene is a poor prognostic factor in individuals with stage IV NSCLC.
