An investigation of the cause of death from cancer

Four thousand seven hundred twenty-eight autopsies performed at the Roswell Park Memorial Institute were reviewed to determine causes of death from cancer. The duration of the disease from the date of diagnosis to death, the primary site of the tumor, a detailed description of the presence or absence of metastatic tumor at a series of sites, and an estimate of the total tumor mass were included in the evaluation. Twenty-three common primary sites were selected for investigation. These sites represented 99% of the total series. Nine causes of death were described. These were respiratory failure, infection, toxic drug reaction, hepatic failure, renal failure, shock or heart failure, adrenal gland failure, electrolyte imbalance, and central nervous system failure. Some of these associations were obviuosly due to the direct destruction of the organ in question. There are some differences, however, comparing lung lesions to hepatic lesions. These and other factors are recited in the text.
