[Clinical picture and diagnosis of cancer of lung in persons of elderly and senile age with residual tubercular changes].

Clinical and roentgenologic manifestations of cancer of lung developing from residual tubercular changes in 32 patients of elderly and senile age were analysed. Clinical and roentgenologic and laboratory criteria of diagnosis of the associated process were determined. Causes of the late diagnosis of cancer of lung were disclosed; it was caused by the low level of work at the medical institution following up the patients suffering from tuberculosis and having residual changes, namely, lack of regular preventive X-ray examinations which occurs in 3/4 patients with the associated process. We came to the conclusion that patients of the elderly and senile age with residual tubercular changes should be referred to the risk group of developing cancer of lung and it's necessary to display oncology alarm to them.
