Objective: To investigate the psychological characteristics of hepatic malignancy patients before interventional procedures and assess associations with related factors. Methods: Two hundred and thirteen patients requiring interventional procedure for hepatic malignancy were asked to complete a survey of health knowledge and psychological symptom on health knowledge questionnaire and SCL-90 before interventional procedure. Logistic regression analysis was employed to determine the association of various demographic, clinical and health knowledge factors with the presence of psychological symptoms in patients. Results: Eight psychological symptom scores, i.e. somatization, obsessive-compulsive tendencies, depression, anxiety, hostility, phobia, paranoid ideations and psychotic states, were significantly higher than the normal range (P< 0.001). Of 213 cases in the study, 49 families (23.00%) concealed the diagnoses of hepatic carcinoma from patients; 135 patients (63.38%) described the prognosis of the disease correctly. It was demonstrated that the correlations between psychological symptoms and related factors, i.e. age, gender, education, interventional procedure times and health knowledge, were statistically significant (P<0.05). Conclusion: Psychological distress is severe in hepatic malignancy patients before interventional procedures. Age, gender, education, interventional procedure times and health knowledge are associated with psychological symptoms which are significant different from the normal range in Chinese.

Computed tomography (CT) findings of hepatic adenoma in veterinary medicine are variable and unlike in human medicine, not defined clearly. A 12-year-old neutered male Shih Tzu presented after a seizure, with weight loss, salivation, and cachexia. An abdominal mass was identified on radiography, and ultrasonographic images showed a mixed echo pattern with marked vascularity. CT showed that the mass originated from caudate lobe, was heterogeneously hypoattenuated compared with the hepatic parenchyma, and had irregular margins. Contrast enhanced CT showed that the mass enhanced like the surrounding liver parenchyma. However, it contained unenhanced areas and enhanced vessels were observed in the arterial phase at the periphery of the mass. The margins of mass were more enhanced in the venous phase than the arterial phase and the hypoattenuating regions within the mass were not enhanced. Greater enhancing in the venous phase is seen with adenomas; however, the heterogeneous enhancement pattern, especially the marginal vascular enhancement and internal hypoattenuating regions, is seen with malignancy. Although this is a single case of hepatic adenoma, the atypical enhanced pattern of this case can provide useful information to predict the malignancy of primary liver tumor.

Vascular tumors of the liver are mesenchymal lesions from endothelial cells. They range from common benign lesions such as haemangioma, intermediate tumors like Kaposi sarcoma, and perivascular epithelioid cell tumor to malignant tumors such as hepatic epithelioid hemangioendothelioma and hepatic angiosarcoma in adults. Pediatric vascular tumors of the liver also include benign, locally aggressive, borderline, and malignant masses with haemangiomas being the most common benign tumors and epithelioid hemangioendothelioma being an uncommon pediatric malignancy. The list of these lesions is completed by nodular regenerative hyperplasia, solitary fibrous tumour, and hepatic small vessel neoplasms (HSVN). Some of these tumors are uncommon and rare. This review article aimed to enumerate hepatic vascular tumors along with their imaging, histopathology, molecular findings for accurate diagnosis that can result in better management.

A 61-year-old man had a F-18 FDG PET/CT scan for evaluation of a common bile duct cancer identified on CT. The PET/CT image showed a hypermetabolic mass in the common bile duct, and a focal area of increased F-18 FDG uptake in segment IV of the liver, which corresponded to a hypoattenuated lesion on non-enhanced CT, and was consistent with hepatic metastasis. The patient underwent choledochojejunostomy with hepatic resection, and pathologic findings were compatible with an eosinophilic abscess in the liver. This case demonstrates that F-18 FDG uptake by an eosinophilic abscess can mimic hepatic metastasis in a patient with a malignancy.

Hepatocellular carcinoma (HCC), a highly malignant disease and the third leading cause of all cancer mortalities worldwide, often responses poorly to current treatments and results in dismal outcomes due to frequent chemoresistance and tumor relapse. The heterogeneity of HCC is an important attribute of the disease. It is the outcome of many factors, including the cross-talk between tumor cells within the tumor microenvironment and the acquisition and accumulation of genetic and epigenetic alterations in tumor cells. In addition, there is accumulating evidence in recent years to show that the malignancy of HCC can be attributed partly to the presence of cancer stem cell (CSC). CSCs are capable to self-renew, differentiate and initiate tumor formation. The regulation of the stem cell-like properties by several important signaling pathways have been found to endow the tumor cells with an increased level of tumorigenicity, chemoresistance, and metastatic ability. In this review, we will discuss the recent findings on hepatic CSCs, with special emphasis on their putative origins, relationship with hepatitis viruses, regulatory signaling networks, tumor microenvironment, and how these factors control the stemness of hepatic CSCs. We will also discuss some novel therapeutic strategies targeted at hepatic CSCs for combating HCC and perspectives of future investigation.

Among 60 children with teratoma, forty-three (71.7 percent) were girls and 17 (28.3 percent) boys, Primary sites were sacrococcygeal in 30 patients (50 percent), retroperitoneal in 12 (20 percent), ovarian in 11 (18.3 percent), testicular in 3 (5 percent), and one in each of nasopharyngeal, gastric, hepatic and pancreatic (1.6 percent, respectively). Fifty-five (91.7 percent) teratomas were benign and 5 (8.3 percent) malignant. Malignant teratomas W8,re detected only in the sacrococcygeal region (16.7 percent). Age greater than 2 mouths at diagnosis, presence of urinary or colonic obstructive symptoms, multiple masses and elevated serum alpha-fetoprotein were indicators of malignancy in the sacrococcygeal region. Tumor size, presence of calcification, and gross apperance (cystic or solid) did not correlate with malignancy. Thirteen (21.7 percent) cases were associated with other anomalies. For the immature teratoma, operative resection without adjuvant chemotherapy was adequate treatment. Three patients with malignant tumors survived, one who received chemotherapy survived 3 years and the others without chemotherapy survived for 5 and 10 years.

Desmoplastic small round cell tumor (DSRCT) is a rare and aggressive malignancy common in young male patient. Typical imaging features of DSRCT include multiple soft tissue masses in the peritoneal cavity, omentum, or mesentery without an organ of origin. This report presents a rare manifestation of DSRCT revealing a solitary large retroperitoneal mass with hepatic metastasis and malignant portal vein thrombosis in 70-year-old women together with the review of literature. The tumor showed a hemorrhagic and necrotic mass with peripheral portion of T2 hypo-intensity and delayed enhancement that indicated desmoplastic stroma with dense cellularity.

Onion (Allium cepa) consumption has been remarked in folk medicine which has not been noted to be administered so far as an adjunct to conventional doxorubicin-based chemotherapy in breast cancer patients. To our knowledge, this is the first study aimed to investigate the effects of consuming fresh yellow onions on hepatic enzymes and cancer specific antigens compared with a low-onion containing diet among breast cancer (BC) participants treated with doxorubicin. This parallel design randomized controlled clinical trial was conducted on 56 BC patients whose malignancy was confirmed with histopathological examination. Subjects were assigned in a stratified-random allocation into either group received body mass index dependent 100-160 g/d of onion as high onion group (HO; n=28) or 30-40 g/d small onion in low onion group (LO; n=28) for eight weeks intervention. Participants, care givers and laboratory assessor were blinded to the assignments (IRCT registry no: IRCT2012103111335N1). The compliance of participants in the analysis was appropriate (87.9%). Comparing changes throughout pre- and post-dose treatments indicated significant controls on carcinoembryonic antigen, cancer antigen-125 and alkaline phosphatase levels in the HO group (P<0.05). Our findings for the first time showed that regular onion administration could be effective for hepatic enzyme conveying adjuvant chemotherapy relevant toxicity and reducing the tumor markers in BC during doxorubicin-based chemotherapy.

Solitary necrotic nodule (SNN) of the liver is a very uncommon benign lesion, and it is detected incidentally as a rule. It is important to differentiate SNN radiologically from various single hepatic nodules because SNN mimics hepatic metastasis, especially in staging work up of known primary malignancy. The reported imaging findings of SNN are well-defined nodule without enhancement or with subtle peripheral enhancement. There has been no report about the target-like SNN of the liver and about the imaging finding of 3T magnetic resonance imaging and positron emission tomography. We report a case of targetlike SNN of the liver, mimicking hepatic metastasis, with findings of various imaging modalities and try to find a cause of this nodule according to the pathologic and literature review.

Objective: To investigate the efficacy of gadobenate dimeglumine (GdBOPTA) enhanced MR imaging for the detection of liver lesions in patients with primary malignant hepatic neoplasms. Materials and Methods: Thirty-one patients with histologically proven primary malignancy of the liver were evaluated before and after administration of GdBOPTA at dose 0.05 or 0.10 mmol/kg. T1-weighted spin echo (T1W-SE) and gradient echo (T1W-GRE) images were evaluated for lesion number, location, size and confidence by three off-site independent reviewers and the findings were compared to reference standard imaging (intraoperative ultrasound, computed tomography during arterial portography or lipiodol computed tomography). Results were analyzed for significance using a two-sided McNemar's test. Results: More lesions were identified on Gd-BOPTA enhanced images than on unenhanced images and there was no significant difference in lesion detection between either concentration. The largest benefit was in detection of lesions under 1 cm in size (7 to 21, 9 to 15, 16 to 18 for reviewers A, B, C respectively). In 68% of the patients with more than one lesion, Gd-BOPTA increased the number of lesions detected. Conclusion: Liver MR imaging after Gd-BOPTA increases the detection of liver lesions in patients with primary malignant hepatic neoplasm.
