ABSTRACT
Surgical treatment of 135 patients with multifocal and metastatic cancer of the lungs and other organs is analyzed. The absence of absolute differential diagnostic differences between true poly-neoplasia and synchronous or metachronous solitary metastases leads to extension of indications to surgical treatment of these patients. Surgical procedures were performed in 109 patients, 37 (33.9%) of them were one-stage. One-stage procedures meet the requirements of radical surgery and are most preferable biologically and clinically. These surgeries decrease treatment duration, prolong survival to 3-5 and more years in many patients. As cytoreductive operations, one-stage resections improve the condition of the patients, enable effective polychemotherapy.
