Immunohistochemical Staining on an Excision Biopsy Specimen as a Diagnostic Modality for Rare Idiopathic Hepatocellular Adenoma: A Case Report.

Hepatocellular adenoma is an extremely rare benign tumor of the liver which predominantly in young women. Its rare incidence with estimated 3-4 cases per 1.000.000 annually makes it a diagnostic challenge. Here we present a 30-year-old female patient with hepatocellular adenoma without classic risk factors. A series of work up tools have been performed in order to diagnose the condition. None but excision biopsy from segmental resection had been showed to increase diagnostic confidence. This case illustrates the role of immunohistochemical staining from excision biopsy as the best diagnostic modality of hepatocellular adenoma as well as therapeutic modality to prevent malignant transformation.

Riedel's Lobe: Clinical Importance of a Rare Variant in Liver Morphology.

Riedel's lobe is a normal variant form of right liver lobe rarely found. Here we report a case of 38 years old female with an incidental finding not revealed in physical examination, but then known to have hepatomegaly by gynecological ultrasonography. Diagnosis of Riedel's lobe was strengthened by similar results on hepatobiliary ultrasonography, abdominal MRI, and diagnostic laparoscopy. Our patient was discharged and had follow up examination three months later. Knowledge regarding this anomaly is essential to be understood because the finding of accessory liver lobe does not always remain asymptomatic as in our patient, but rather can be related to significant clinical complication.

Evaluation of Acoustic Radiation Force Impulse (ARFI) for Fibrosis Staging in Chronic Liver Diseases.

BACKGROUND: acoustic radiation force impulse (ARFI) is a new proposed noninvasive method for liver fibrosis staging. Integrated with B-mode ultrasonography, ARFI can be used to assess liver tissue condition. However its diagnostic accuracy is still being continuously evaluated. Also, there is lack of data regarding the utilization of ARFI in our population. This study aimed to evaluate the diagnostic value of ARFI as an alternative noninvasive modality for fibrosis staging in chronic hepatitis B and hepatitis C patients in our population. METHODS: we conducted cross-sectional comparison of ARFI imaging and transient elastography on patients who underwent liver biopsy at Cipto Mangunkusumo Hospital. Fibrosis staging using METAVIR scoring system presented as standard reference. A total of 43 patients underwent liver biopsy was evaluated by ARFI imaging and transient elastography. Cut-off values were determined using receiver-operating characteristic (ROC). RESULTS: both liver stiffness determined by ARFI and transient elastography (TE) were moderately correlated with METAVIR score with value of 0.581 and 0.613, respectively (both P<0.01). Diagnostic accuracy of ARFI predicted significant fibrosis (F≥2) with area under receiver operating characteristic curve (AUROC) of 0.773 (95% CI 0.616-0.930) and even better for cirrhosis (F4 fibrosis), expressed as AUROC of 0.856 (95% CI 0.736-0.975). Transient elastography was better for significant fibrosis with AUROC of 0.761 (95% CI 0.601-0.920) and was best for prediction of cirrhosis, expressed as AUROC of 0.845 (95% CI 0.722-0.968). CONCLUSION: ARFI is provided with more convenient evaluation of liver tissue condition, and its diagnostic accuracy is not significantly different from TE for staging liver fibrosis.

Comparison Between Neutrophil-Lymphocyte Ratio and Systemic Immune-Inflammation Index as Predictors of One-Year Survival in Patients with Untreated Advanced Hepatocellular Carcinoma.

BACKGROUND: Patients with hepatocellular carcinoma (HCC) generally only come for treatment when cancer has reached an advanced stage, with very limited treatment options. There has not been an accurate predictor marker to be able to identify which group of patients may have better survival. This study wanted to analyze the role of the inflammatory status indices as predictors of 1-year survival in patients with advanced HCC who did not undergo therapy. METHODS: This study has a retrospective cohort design using secondary data on subjects with advanced HCC who did not undergo therapy at Cipto Mangunkusumo Hospital and Dharmais Hospital. The neutrophil-lymphocyte ratio (NLR) and systemic immune-inflammation index (SII) were evaluated for their role as predictors of 1-year survival based on the area under receiving operator curve (AUROC). The best optimal cut-off for NLR and SII was decided based on the Youden index, followed by survival analysis based on those cut-offs. Confounding factors were analyzed with multivariate cox regression analysis. RESULTS: A total of 196 subjects were included in the data analysis. One-year survival was 6.6%, with a median survival of 56 days (95% CI: 46-67). The NLR had a discriminatory ability based on AUROC of 0.667 (95% CI: 0.536-0.798; p = 0.044), with the optimal cut-off point to differentiate survival was 3.7513. The SII has a discriminatory ability based on AUROC of 0.766 (95% CI: 0.643-0.889; p = 0.001), with the optimal cut-off point to distinguish survival was 954.4782. SII had superiority in discriminatory ability (p = 0.0415). CONCLUSIONS: The discriminatory ability based on AUROC of SII was better than that of NLR in predicting 1-year survival in patients with advanced HCC who did not undergo therapy.
