[Value of ultrasound-guided cytopuncture in the diagnosis of tumors in cirrhosis. Study of 29 cases].
Ultrasonically guided fine needle aspiration biopsy is known to be of great value in the diagnosis of malignant liver disease, with an overall accuracy rate of 73-94 p. 100. However, investigators have essentially reported cases of liver metastases. In this report, we examined the diagnostic value of this method in the specific case of tumors associated with cirrhosis. Twenty-seven patients with cirrhosis (20 alcoholic, 4 post-hepatitis, 3 hemochromatosis) with ultrasonically suspected hepatic malignancy were studied. They all presented severe blood clotting disturbances and/or ascites. At the end of the study, all patients had proven malignancy (by post mortem biopsy in 14 cases and/or serum AFP greater than 500 microgram/l in 17 cases). There were 25 primary and 2 metastatic tumors. Twenty-nine fine needle aspiration biopsies were performed under ultrasonic guidance. material suitable for cytologic evaluation was obtained in 25 patients. In 14 cases, a diagnosis of malignant involvement of the liver was firmly established by cytological examination; it was suggested in 4 other cases. Tumor typing was possible in 12 primary and 2 metastatic tumors, in agreement with the proven diagnosis. The present study shows that fine needle aspiration biopsy under ultrasound guidance is a safe and accurate diagnostic procedure in malignant liver disease associated with cirrhosis.
