Histomorphological features of combined forms of tuberculosis and lung cancer
Journal Title: Медичні перспективи - Year 2017, Vol 22, Issue 1
Abstract
The were studied pathological features of combined forms of tuberculosis and non-small cell lung cancer in 72 patients who underwent radical surgical resection interventions from transsternal access with mediastinal lymph node dissection, with predominance of pneumonectomy - 63.9%. There were identified three main categories of pathological changes: cancer on the background of post-tuberculosis changes, cancer in tuberculoma, cancer in the wall of the active cavity. Post-tuberculosis changes were presented by dense centers, fibrosis, cirrhosis areas, sanitized cavities with histological predominance of coarse fiber connective tissue with giant cell granulomas, with areas characterized by the appearance of the lung tissue with atypical proliferation and metaplasia of bronchopulmonary epithelium, which is a precancerous condition. This malignant tumor process was presented mainly by adenocarcinomas and squamous cell cancer and differred by polymorphic macro- and microscopic picture. Cancer in tuberculoma and fibrous wall cavity differed by pronounced activity of tuberculosis process in the form of lymphohistiocytic infiltration, foci of caseous necrosis and presence of expressed granulation layer of Pirogov-Langhans’ cells. The basic morphological causes of carcinogenesis due to secondary changes of lung tissue in patients with tuberculosis were determined. The features of metastasis of malignant tumors on the background of specific tuberculous and post-tuberculosis changes in regional lymph nodes and the interrelation between the frequency of metastatic lesions with severity of tuberculosis and post-tuberculosis changes in them were studied; this has clinical significance in the surgical treatment of patients with concomitant forms of tuberculosis and lung cancer.
