Diagnostic accuracy of color Doppler in diagnosis of Hepatocellular carcinoma taking histopathology as gold standard
Abstract: Hepatocellular carcinoma (HCC) is the fifth most common cancer in the world and the third most common cause of cancer mortality. Despite the high numbers of patients diagnosed worldwide, HCC continues to pose challenging clinical problems. Good-quality ultra sound with careful evaluation of the entire liver can be a screening examination for HCC in patients at risk. The aim of the study was to determine the diagnostic accuracy of the Doppler sonography for differentiation of hepatocellular carcinoma (HCC) from other focal liver lesions by taking histopathology as a gold standard. It was a cross-sectional survey, conducted in the Department of Diagnostic Radiology, King Edward Medical University/Mayo Hospital, Lahore in one year from 13-12-2010 to 12-12-2011. A total of 70 patients were included in this study with focal lesions on ultrasound are included while pregnant patients are excluded. After evaluating by Doppler sonography and doing core biopsy, the patients were sent to the Department of Pathology, Mayo Hospital for histopathological examination. Histopathology was assessed for confirmation of positive and negative cases. Mean age of the patients was 60.9 ± 4.7 years. Out of 70 patients, 47 patients (67.1%) were male while remaining 23 patients (32.9%) were female. On Doppler sonography 37 cases were positive for hepatocellular carcinoma and 33 cases were negative while 36 cases were positive and 34 negative on histopathology. On Doppler sonography, sensitivity (94.4%), specificity (91.1%), diagnostic accuracy (92.8%), positive predictive value (91.8%) and negative predictive value was 93.9%. We concluded that Doppler sonography is a useful method for differen- tiation of Hepatocellular carcinoma from other focal liver lesions, detection and characterization of hepatocellular carcinoma.
