[Radiographic and endoscopic studies in the diagnosis of persistent growth and recurrence of central cancer of the lung after radiotherapy].

Roentgenologic and bronchoscopic examination was performed in 75 patients with central carcinoma of the lung 3-5 months following radiation treatment and every 3-4 months thereafter up to 36 months and longer to establish optimal schedule of those procedures to evaluate response and timely diagnosis recurrence or progression of disease. Complex application of X-ray and endoscopy in lung cancer patients every 3-4 months following radiotherapy assures timely diagnosis of relapse or progression.
