A comparative analysis of surgical treatment of non-small cell carcinoma of lung was made in 64 patients of senile age and more young patients. It was stated, that preference should be given to the partial lung resections (lob- and segmentectomies). The authors recommended to avoid pneumoectomy and typical resection of the lung as non-radical operations accompanied by high rate of local recurrences. The comorbidity background of patients should be thoroughly investigated before planning of surgery. If necessary, a surgical treatment of accompanied vascular pathology should be fulfilled as the first stage before oncology surgery.
