Abstract
One hundred seventy-three cases of primary carcinoma of the gallbladder were analyzed. In the group studied they made 2.11 per cent of all malignant tumors found at autopsy and were found in 1.89 per cent of all cases in which operation was done on the biliary tract. There was no appreciable change in the incidence of this tumor at autopsy during the period studied (1918-1948) at the Los Angeles County Hospital. Sixty-eight per cent of the cases were in females. A particularly high incidence was noted in Mexican females.
Upper abdominal pain, loss of weight, nausea and vomiting, jaundice, and palpable mass or enlarged liver were the most common clinical features. Approximately one-third of the patients in whom the lesion was found at operation and one-fifth of all the patients whose records were studied had a history of chronic gallbladder disease.
All but two of the 38 patients operated on were dead or had clinical recurrence within two years. One was alive and well 12 years after cholecystectomy.
The most common gross appearance, particularly at autopsy, was a large tumor mass replacing the gallbladder and radiating to nearby organs, particularly the liver. In about one-third of the cases the tumor was grossly limited to the gallbladder. Polypoid tumors occurred in only about 10 per cent of the cases and most of the tumors were diffusely growing adenocarcinoma. Perforation appeared in nine cases, usually with fistula to the gastrointestinal tract. All of the tumors were histologically adenocarcinoma, usually of simple glandular structure. No purely squamous cell growth occurred.
Gallstones were found in 79.8 per cent of the cases.
