[Combined treatment of lung cancer]

The results of surgical and combined treatment of 2025 cases of differentiated cancer of the lung are compared. There was no difference in treatment results for stages I-II. In stage III tumor treatment, preoperative radiotherapy or postoperative polychemotherapy were followed by relative increase in 5-year survival. When intrathoracic lymph nodes were involved, combined treatment including pre- or postoperative radiotherapy was a procedure of choice since it was followed by better end results.
