Hepatic Steatosis, Fibrosis, and Cancer in Elderly Cadavers.
Summary of "Hepatic Steatosis, Fibrosis, and Cancer in Elderly Cadavers."
The incidence of hepatic steatosis, fibrosis, and cancer in the elderly population remains unknown. Human cadavers used in anatomy teaching, which come largely from older adults, may provide liver tissue for examining their pathologies. Livers were obtained from 68 cadavers (mean age 82.1 ± 10.4 years) with diverse causes of death in the Anatomy course at Mount Sinai School of Medicine. Paraffin sections were stained with hematoxylin and eosin and Sirius red and evaluated for steatosis, fibrosis, cancer, and lipofuscin. Tissue preservation was graded as good in 38.2% of the embalmed livers, fair in 36.7%, and poor in 25.0%. Steatosis was observed in 35.3% of the livers, central vein fibrosis in 49.2%, perisinusoidal fibrosis in 63.2%, portal tract (PT) fibrosis in 47.0%, septa formation in 44.1%, bridging fibrosis in 30.8%, and cirrhosis in 4.4%. One hepatocellular carcinoma (HCC) and six metastatic tumors were detected. Lobular inflammation occurred in 20.8% of the livers and PT inflammation in 38.8%. Nine livers showed minimal change. Lipofuscin was detected in 60.2% of the livers. Steatosis, fibrosis, and cancer are highly prevalent in elderly cadavers with diverse causes of death. The prevalence of steatosis and fibrosis is consistent with the data in patients with specific liver diseases. Steatosis alongside fibrosis can accelerate the progression of fibrosis to cirrhosis and ultimately HCC. Though not indicated as the primary cause of death, the liver injury may have compromised hepatic functions and enhanced disease susceptibility, thereby exacerbating the health conditions in this elderly population.

Medical and Biotech [MESH] Definitions
A condition in which the hepatic venous outflow is obstructed anywhere from the small HEPATIC VEINS to the junction of the INFERIOR VENA CAVA and the RIGHT ATRIUM. Usually the blockage is extrahepatic and caused by blood clots (THROMBUS) or fibrous webs. Parenchymal FIBROSIS is uncommon.
Liver Cirrhosis, Alcoholic
FIBROSIS of the hepatic parenchyma due to chronic excess ALCOHOL DRINKING.
Liver Cirrhosis, Biliary
FIBROSIS of the hepatic parenchyma due to obstruction of BILE flow (CHOLESTASIS) in the intrahepatic or extrahepatic bile ducts (BILE DUCTS, INTRAHEPATIC; BILE DUCTS, EXTRAHEPATIC). Primary biliary cirrhosis involves the destruction of small intra-hepatic bile ducts and bile secretion. Secondary biliary cirrhosis is produced by prolonged obstruction of large intrahepatic or extrahepatic bile ducts from a variety of causes.
Housing For The Elderly
Housing arrangements for the elderly or aged, intended to foster independent living. The housing may take the form of group homes or small apartments. It is available to the economically self-supporting but the concept includes housing for the elderly with some physical limitations. The concept should be differentiated from HOMES FOR THE AGED which is restricted to long-term geriatric facilities providing supervised medical and nursing services.
A cancer registry mandated under the National Cancer Act of 1971 to operate and maintain a population-based cancer reporting system, reporting periodically estimates of cancer incidence and mortality in the United States. The Surveillance, Epidemiology, and End Results (SEER) Program is a continuing project of the National Cancer Institute of the National Institutes of Health. Among its goals, in addition to assembling and reporting cancer statistics, are the monitoring of annual cancer incident trends and the promoting of studies designed to identify factors amenable to cancer control interventions.
