[Current methods in the diagnosis and therapy of lung cancer]

A 45-year experience of diagnosis and treatment of lung cancer is presented. In groups at high risk of cancer, photoroentgenographic screening has proved effective. The use of out-patient complex pulmonologic examination serves to improve identification of central cancer. Early cancers of the lung can be reliably detected in 92.2% of patients with central cancer and in 92.6%-peripheral localizations of tumor. After radical surgery, 5-year survival in cases of stage I tumor was 63.5: stage II-43.5 and stage III-22.9%, mean 5-year survival (irrespective of stage) being 37%. Postoperative radiation was shown to be followed survival over 5 years in cases of non-small cell carcinoma (N2). Early diagnosis and combined therapy are key in raising efficacy of lung cancer treatment.
