奈良県立医科大学における過去25年間の剖検症例の統計学的検討

Abstract

Autopsies of 3305 cases performed at the Department of Pathology, Nara Medical University and affiliated hospitals from 1974 to 1998 are analyzed. The numbers and rates of autopsy were highest in 1980, 224 cases and 48.4% respectively, and subsequently they have declined, finally to 53 cases and 13.0% respectively in 1998. The frequencies of main disorders were neoplasms (1853 cases), circulatory disturbances (528 cases), inflammation (466 cases), regenerative and reperative disorders (299 cases), degenerative and metabolic disorders (164 cases), congenital diseases (141 cases) and trauma and others (34 cases) in this order. The frequent anatomical diagnoses were lung cancer (436 cases), liver cirrhosis (293 cases), liver cancer (262 cases), gastric carcinoma (258 cases), leukemia (123 cases), multiple primary cancer (120 cases), myocardial infarction (108 cases), pneumonia (105 cases), pancreatic cancer (104 cases), and malignant lymphoma (88 cases). Among them, the rates of multiple primary cancer, lung cancer, and leukemia showed a tendency to increase chronologically, while gastric carcinoma showed a tendency to decrease. The value of autopsy extending our knowlege of diseases is emphasized and means to improve autopsy rate are discussed.
