title: Clinical significance of preoperative liver scintigraphy in gastric cancer.
abstract: The surgical and liver scintigraphic findings were compared for evaluation of preoperative diagnostic value in 146 cases of gastric carcinoma. Correct diagnosis was found in 95% with a false negative rate of 2.7% and a false positive rate of 27%. In all the false negative cases, the size of all space-occupying lesions within the liver was less than 3 cm. in diameter. In view of the high percentage of correct diagnosis (95%), we believe that the preoperative liver scintigraphy is very useful clinically. Furthermore, we documented that liver metastasis is a late complication of gastric cancer and suggest that new diagnostic tools are needed to assess the presence of nodal metastasis, serosal infiltration and peritoneal dissemination.
