摘要
Sudden unexpected death (SUD) in patients with malignancy has not been comprehensively studied. We defined SUD as intrinsic natural death within 24h after initial clinical presentation of the disease responsible for the death. Intra- and postoperative death and cases associated with a myelosuppressive state were excluded. Of 2,216 autopsy cases with malignancy registered at Saitama Cancer Center, Japan, 28 SUD cases (1.3%) were studied clinicopathologically. Fifteen cases (53.6%) died of non-neoplastic cardiovascular events (CVEs), with acute myocardial infarction (AMI) being the most common death (n=13). Ten cases (35.7%) died of neoplasm-related complications (NRCs), and a miscellaneous pathophysiology was apparent, including cardiac involvement by tumor cells (n=3), fistula formation between great vessels and the alimentary canal (n=3), hepatic rupture (n=2), cardiac tamponade (n=1), and neoplastic pulmonary emboli (n=1). An anaphylaxis reaction (AR) was the cause of SUD in three cases (10.7%). Our results imply that the main route for prevention of SUD in patients with malignancy is incorporation of measure against ischemic heart disease. In addition, a variety of mechanisms causing SUD as a complication of malignant neoplasms should be recognized, including AR. Accumulation of SUD cases is necessary to better understand the causes of SUD in patients with malignancy. (c) 2006 Elsevier GmbH. All rights reserved.
