The results are presented of 5-year experience with therapy of concurrent neoplasia and atherosclerotic lesions of the aorta and peripheral arteries gained at the Center for Oncosurgery, Regional Oncological Dispensary, Chelyabinsk. The analysis was concerned with the treatment received by 118 patients, irrespective of tumor stage or localization: surgical correction of blood flow was carried out in 60. Clinically significant atherosclerotic lesions of the aorta and peripheral arteries in a cancer patient should not be regarded as absolute or relative contraindication for combined treatment. Atherosclerotic occlusion of the femoral or shin arteries was managed conservatively in most cases (p<0.05). In cases of similar lesions of the carotid arteries and aortal aneurysm, surgical correction of blood flow was mostly used.
