Abstract
The simultaneous occurrence of cancer of the pancreas in husband and wife is reported. Both patients shared two dietary idiosyncrasies--namely, (1) the ingestion of copious amounts of margarine in which they cooked all their food and (2) the addition of 'coffee syrup', a liquid concentrate of coffee, to their ground coffee before percolation. The possible role of the latter in the aetiology of pancreatic cancer is discussed.
