[Repeat uni- and bilateral operations in surgery for multiple primary cancer of the lungs and intrathoracic metastases].

Repeated uni- and bilateral resections of the lungs conducted from 1963 to 01.01.91 at the Department of Surgery of the Lungs and Mediastinum of the National Research Center of Surgery, USSR AMS for primary multiple carcinoma (13 patients) and metastatic lesions (32 patients) accounted for 1.3% of all operations in lung carcinoma. Such interventions are more justified in differentiated forms of primary multiple carcinoma and in solitary and occasional metastases of malignant tumors of various localization to the lungs. Morphological signs are the main differential diagnostic criteria of primary multiple carcinoma and intrapulmonary metastases. The main principle of surgical treatment of patients with primary multiple carcinoma and metastatic involvement of the lungs is an economical character of the operation with maximally admissible, from the oncological standpoint, preservation of functionally valuable pulmonary tissue. The combined method of treatment (operation + drug antineoplastic therapy) should take the leading place in the management of patients with intrapulmonary metastases of malignant tumors.
