[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.

[Criteria for evaluating drug treatment in malignant tumor metastases to the lungs].

The paper deals with the description of a procedure of assessment of the effectiveness of chemotherapy of pulmonary metastases on the basis of changes of metastasis size in the course of treatment. Inter-perpendicular diameters of metastases were determined by the formula: (Formula: see text), while spherical modes -- (Formula: see text). In cases of multiple metastases, the sum total of all volumes was calculated; for disseminated ones -- the sum total of the volumes of nodes most distinctly seen in radiograms.
