Abstract
Objective – to determine the nature and localization of concomitant cancers in patients who died from various causes in a multidisciplinary hospital.
Material and methods. A retrospective analysis of autopsy protocols (2923) for 9 years (2016–2024) was carried out. All cases with cancerous tumors were divided by gender (148 men and 163 women) and age (under 50 years, 51–70 years and over 70 years), and into 16 groups depending on the localization of the tumor process.
Result. Our study showed that patients who died from myocardial infarction, cerebral stroke (more often hemorrhagic), peritonitis, pneumonia or pulmonary thrombosis had cancer of a certain organ as a concomitant disease in the pathanatomic diagnosis. Colon cancer was most often detected (73 cases, or 23.5%), and cancers of the digestive tract account for 33.8% of cases. Stomach cancer (27 cases) and prostate cancer (24 cases), as well as cancers of other organs, are lagging far behind intestinal cancer.
Conclusion. An analysis of 2923 autopsy protocols showed that cancer is more common in patients over 50 years of age. Therefore, efforts should be directed to the medical examination of elderly and senile people for early detection of oncopathology and for timely and effective treatment of tumor diseases. Our figures of oncopathology in patients with acute diseases (myocardial infarctions, strokes, peritonitis, embolism of pulmonary and mesenteric vessels) mostly coincide with statistical data on cancer incidence in the Russian population.
Key words: tumor diseases, localization of cancerous tumors, mortality.
