Chapter 11: Cancer of the Gallbladder
James E. Everhart, M.D., M.P.H.
About 3,000 cases of gallbladder cancer were estimated to have occurred in 2004 (Table 1). Gallbladder cancer was the only digestive system malignancy that occurred predominantly among women (nearly twice the age-adjusted rate of men) and was one of the few nongenital cancers that had a female predominance. It was predominantly a diagnosis of the elderly, with a median age of diagnosis of age 73 years (PDF, 28 KB) , the highest of any digestive system cancer. Age-adjusted rates were too low to draw inferences about ethnic differences in risk. Incidence of gallbladder cancer declined by 42.2 percent from 1979 to 1997, and was then stable through 2004 (Figure 1). Five-year survival increased modestly to about 9 percent. Outpatient and inpatient data were too sparse to draw inferences, except that the rate of hospitalization with gallbladder cancer declined substantially until the mid-1990s and has been stable since (Figure 2).
Because of low survival, gallbladder cancer mortality was similar to incidence. As underlying cause, there were nearly 2,000 deaths in 2004 and just under 11,000 YPLL prior to age 75 years (Table 3), which reflects the older age at which gallbladder cancer occurred. Rates were 6.8 times as high in the oldest age group (65 years and older) as among those ages 45–64 years. Age-adjusted mortality rates were higher for blacks than whites, and for females than males. The death rate for gallbladder cancer declined by 47 percent between 1979 and 2004 (Figure 3). Because gallstones are the major recognized risk factor for gallbladder cancer, it is of interest that there was a similar decline (56.1 percent) in gallstone disease-related mortality over that period.
