In most developed industrialized countries of the world, lung cancer is the most
common form of malignant neoplasms in men. At present
time every twentieth man dies from this disease.
In many regions, including our country, there is a tendency to increase
morbidity and mortality rates from lung cancer. So, from 1970 to 1986
the incidence of lung cancer in men in the USSR increased from 35.6 to 63.3 0/0000 or
77.8%, in women from 8.1 to 11.8 o / 0000 or 45%. In 1987 in the USSR

prognosis of surgical treatment of patients with advanced stages of lung cancer,
characterized by extrapulmonary tumor spread, depends on a number of
factors. The most important of these are: the nature and extent of lymphogenous

the nature and extent of lesions of extrapulmonary anatomical structures and

Adverse factor affecting long-term results

tumors are usually observed massive lymphogenous metastasis and
multiple lesions of extrapulmonary anatomical structures and organs of the chest cavity. Five-year survival for such “giant” tumors
amounted to only 10.2%. The data obtained allow to note clearly
traceable inverse relationship between the size of the primary tumor
node and long-term results of surgical treatment.
The prevalence of the tumor process are the nature and
sizes of tumor lesions of various extrapulmonary anatomical structures and
organs of the thoracic cavity. The presence of their multiple lesions suggests
neglect of the blastomatous process, its aggressiveness. As a rule, these
patients noted the presence of metastases in mediastinal lymph nodes and large

organs of the thoracic cavity were performed by multiple expanded combined

worse than after single resections and were respectively 18.1% and 23.8%.
The long-term results of surgical interventions also depended on the nature of
