In parallel, ultrasound-guided fine needle aspiration cytology or needle biopsies were performed in some cases suspected for liver metastasis. The ultrasound diagnosis of liver metastasis were correct in 286 (94.7%) of 302 cases. On laparotomy, 52 cases of liver metastasis were further found from 890 patients who had shown negative findings. The overall accuracy was 94.3%, sensitivity was 94.7%, specificity was 94.2%, positive predictive value for metastatic Ca. was 84.6%, and negative predictive value was 98.1% in the diagnosis of liver metastasis. US-guided liver aspiration cytology was performed in 79 cases, malignant cells were found in 67. The overall accuracy rate was 84.8%, with a sensitivity of 85.9%, a specificity of 100%, and a positive predictive value of 100%. A histologic study of tissue fragment preparations was performed for 45 of 53 cases with 21-gauge biopsy needles by histologic examination biopsy. The overall accuracy rate of the histologic biopsy evaluation was 88.7%, with a sensitivity of 88.2%, a specificity of 100%, and a positive predictive value of 100%. False-negative results were seen in 11 cases of the cytologic, and in 6 cases of the biopsy specimens. Combined cytology and biopsy evaluations were performed in 38 cases. The histologic diagnosis were obtained in 45 cases by histologic biopsy, and in 16 cases only by aspiration cytology. There were not any false-positive result or any serious complications in either examination. The majority of liver metastases showed varied small (less than 30mm), multiple lesions in the liver.
