 note = {The relationship between gallbladder stones (GBSs) and gallbladder carcinomas (GBCs) was studied in 991 patients with GBSs and 66 patients with GBCs who were operated upon in the Niigata University Hospital during a 20 years' period between 1969 and 1988. The frequency of GBCs in patients with GBSs was 3.4% in average, and become higher in accordance with patients' age. On the other hand, the incidence of GBSs in the entire GBC series was 53.0%. A higher incidence of GBCs associated with GBSs was found in patients with age over 70 than in the younger groups. Cholesterol stones were most frequent (71.1%) of all three types (bilirubinate : 18.4%, black stones : 10.5%) in the entire GBC series. A lower proportion of cholesterol stones was, however, demonstrated in patients older than 70, especially in the female. Regardless of types, GBSs themselves might play an important role in developement of GBCs in the older patients. In contrast, cholesterol stones in particular might participate in the occurence of GBCs in the younger patients.},
