When digestive system cancers were examined separately (Table 3), death rates from cancers of the esophagus, stomach, colon, and rectum were generally inversely associated with aspirin use. No as sociations were seen between aspirin use and other gastrointestinal cancers including pancreas, liver and gallbladder, and peritoneum (data on these cancers not shown). There were few deaths from cancers of the esophagus, stomach, and rectum in women. Cancer of the small intestine could not be analyzed.
