N2  - Background: Worldwide, lung cancer is the most common cancer in incidence and mortality, Radiotherapy is very important in treatment of lung cancer, required for almost 40% of patients with lung cancer,technologic advances in radiation therapy have contributed to improvements in local control, decreased toxicity.Patients and methods:40 Patient were simulated using CT simulator,2 plans were done: a}Two dimensions(2D.) plan:Two parallel opposed fields by isocentric technique (virtual plan) up to 40Gy (phase1) then 3d conformal for 20-26 Gy(phase2)B}Three dimensions (3D.) plan: conformal plan by three to five fields. Plan was evaluated by max.,min. and mean dose using dose volume histogram(DVH) as well as: 1)Lung :V20 (volume of lungs receiving 20 Gy ):<35%-40%,3)Heart:V30 (volume of heart receiving 30 Gy):<46%,4)Spinal cord:<46 Gy
