[Incidence of metastatic lesion of different groups of the intrathoracic lymph nodes in lung cancer (based on research data on surgical preparations)].

The study was concerned with the frequency of metastatic spread of lung cancer to intrathoracic lymph nodes versus lung lobe distribution of malignancy in 299 cases of surgical treatment. In cases of primary tumor in any lobe of both lungs, metastases were detected primarily in the pulmonary and bronchopulmonary lymph nodes. A decreasing frequency of metastases was observed from the intrapulmonary lymph nodes to those of the root of the lung and mediastinum.
