Abstract: With the development of medical technology, methods for treatment of lung cancer gradually diversified. Radiotherapy and chemotherapy have gradually become the main methods of treatment. Clinical study have found that simply adopting one kind of treatment, cannot achieve ideal control, with the result of  low 5 year survival rate, and high recurrence rate and metastasis. Combining chemotherapy and radiotherapy, can achieve better effect than that by using single method of treatment, as nonsmall cell lung cancer (NSCLC) is particularly sensitive to the chemotherapy. Recent clinical findings indicate that treating late NSCLC patients with combined therapy methods could achieve significant clinical effect.

Key words: Carcinoma, nonsmallcell lung, Radiotherapy, Drug therapy
