[Roentgenological semeiotics of small cell lung cancer]

The study was concerned with description of roentgenologic semeiotics of central and peripheral small cell lung cancer in 141 patients receiving chemoradiation therapy. The frequency of carcinoma metastasis into intrathoracic lymph nodes was high. Small cell lung cancer showed a good response to conservative treatment, which, in particular, manifested itself in regression of metastases into intrathoracic lymph nodes.
