The pathomorphological changes that characterize lung cancer are largely associated with the special property of the cells that form the tumor. Among these special properties inherent in cancerous tumor cells, there are: autonomy of growth, uncontrollability

According to the topographic and anatomical sign, bronchogenic cancers are usually divided into central and peripheral. This takes into account the location of the tumor in the lung and its relation to the bronchial tree. The

Differentiated tumors include squamous cell carcinoma with keratinization and without it, as well as highly and moderately differentiated adenocarcinoma. Considering the special biological properties of squamous cell low-grade lung cancer, poorly differentiated adenocarcinoma and undifferentiated forms

So, when the tumor is located in the upper lobe of the right lung, as a rule, the superior vena cava and unpaired veins, the lateral wall of the trachea, and the ribs are involved

The nature of the surgical treatment and its results in patients with lung cancer largely depend on the degree and characteristics of the tumor metastases of the tumor of the regional lymphatic collectors. Their removal within

In the bronchopulmonary lymph nodes, two groups are distinguished: Actually intrapulmonary and root . The border between them is somewhat arbitrary: a plane is taken for it, mentally drawn vertically through the “gate” of the lung. In addition, the relationship

The left paratracheal nodes, as on the right, are a continuation of the left tracheobronchial nodes and are located higher along the left side wall of the trachea. As a rule, they are weakly expressed and

Among the lymph nodes of the neck, superficial and deep are distinguished, and the latter, in turn, are divided into front and side. Superficial lymph nodes of the neck are located on the external fascia. The

A study of the topography and structural details of the discharge vessels from various lobes of the lungs by injection showed that to the right of the upper lobe are two paths that are most constant: the

The right tracheobronchial and paratracheal groups of lymph nodes, interconnected by numerous lymphatic vessels, form a reservoir of ascending lymphatic current. Reaching within the mediastinum of the upper sections, this collector further extends to the neck,
