Primary liver tumors represent 0.6% to 1.3% of neoplasms in dogs. Hepatocellular carcinoma (HCC) is the most common liver tumor. It is divided into three morphological groups: massive, nodular and diffuse. The presumptive diagnosis is made through imaging tests, such as ultrasound, although confirmation is made by histopathology. Surgery remains the treatment of choice for massive tumors, but there is no standard treatment for nodular and diffuse forms. This study aimed to report a case of prolonged survival in a dog with diffuse HCC, treated with metronomic chemotherapy and palliative care including non-steroidal anti-inflammatory and low-dose naltrexone.

Abstract Introduction. Moldova is the European country with the highest incidence of hepatocellular carcinoma (HCC) in both sexes. There is, however, no data comprehensively describing the presentation and the risk factors of HCC in the country. We decided to analyze cases of HCC recently received in a tertiary healthcare Institution from Chisinau, the Moldovian capital. Methods. A series of 148 primary liver tumors including 139 cases of HCC were retrospectively analyzed for demographic features, serological and biochemical data, and clinical presentation. Results. The mean age of patients was 59 ± 10 years (range: 19-66) with a M:F sex ratio of 1.9. Tumors appeared on full-blown liver cirrhosis in 83% of cases and were composed of multiple nodules at diagnosis in 36% of patients. Serum Alpha-fetoprotein was exceeding 10ng/mL in 76% of cases. Liver tumor and hepatitis were co-discovered in 34% of cases. More than 81% of hepatocellular carcinomas were associated with at least one hepatitis virus. Carriers of anti-hepatitis C virus were predominating (55% of cases) over patients seropositive for hepatitis B virus surface antigen (36%). Half of the latter were also infected with hepatitis Delta virus. In total, dual or triple infections were present in 24% and 7% of cases. Conclusions. The burden of infections with hepatitis viruses is particularly important in Moldova and corresponds to a situation commonly observed in countries of the Southern hemisphere. A pro-active policy of screening for persistent liver infection targeting population at risk of HCC (> 50 years) and coupled with the distribution of antivirals in positive cases should be rapidly implemented in Moldova to reduce incidence or primary liver cancer.

Introduction. Primary hepatic lymphomas (PHLs) are rare liver tumors, frequently misdiagnosed preoperatively. As these tumors could be successfully treated with chemotherapy, their early recognition is essential, potentially, to avoid useless surgery. We report on the case of a cirrhotic patient with hemochromatosis who presented a PHL, initially diagnosed as a hepatocellular carcinoma (HCC), and we analyze recent data from the literature on this subject. Case Presentation and Review of the Literature. A 45 mm liver tumor was found is a 68-year-old man with alcohol cirrhosis and hemochromatosis. At imaging, the diagnosis of HCC was suspected according to vascular characteristics and the presence of cirrhosis. FDG PET scan showed a solitary hypermetabolic liver tumor. Tumor markers were negative. Surgery consisted in left lateral hepatectomy. At pathology, the diagnosis of the primary hepatic marginal zone B cell lymphoma of mucosa-associated lymphoid tissue (MALT) type was demonstrated. Twenty-two articles reporting 33 cases of true PHL of MALT type were found. Presentation lacked specific symptoms (70% asymptomatic). Half of patients were suspected to have other etiologies of liver mass (HCC, intrahepatic cholangiocarcinoma), and thus diagnosis was established postoperatively. In the patient, diagnosis was made by preoperative biopsy, and chemotherapy was first-line treatment. Discussion. Preoperative diagnosis of PHL, and particularly of primary hepatic MALT lymphoma, is challenging. This case illustrates that PHL remains to be considered among the differential diagnosis of isolated solid liver tumors. Further, it indicates that biopsy could be still indicated in case of suspected HCC in cirrhotic patients, particularly in the presence of unusual findings such as the combination of a FDG PET scan positive tumor in the absence of elevated alpha-fetoprotein.

Hepatocellular carcinoma (HCC), the most common form of primary liver tumors, is the fifth cancer in the world in terms of incidence, and third in terms of mortality. Despite significant advances in the treatment of HCC, its prognosis remains bleak. Transarterial radioembolization with radiolabeled microspheres and Lipiodol has demonstrated significant effectiveness. Here we present a new, simple radiolabeling of Lipiodol with Yttrium-90, for the potential treatment of HCC.

Post Transcriptional Regulation

Hu-antigen R (HuR) is a post-transcriptional regulator that belongs to the embryonic lethal abnormal vision Drosophila-like family (ELAV). HuR regulates the stability, translation, subcellular localization, and degradation of several target mRNAs, which are implicated in carcinogenesis and could affect therapeutic options. HuR protein is consistently highly expressed in hepatocellular carcinoma (HCC) compared to the adjacent normal liver tissue and is involved in the post-transcriptional regulation of various genes implicated in liver malignant transformation. Additionally, HuR protein seems to be a putative prognosticator in HCC, predicting worse survival. This review summarizes the recent evidence regarding the role of HuR in primary liver tumors, as presented in clinical studies, in vitro experiments and in vivo animal models. In conclusion, our review supports the consistent role of HuR protein in the development, prognosis, and treatment of HCC. Additional studies are expected to expand current information and exploit its putative employment as a future candidate for more personalized treatment in these tumors.

Gene And Protein Expression

The physiological role of autophagy in the progression of liver diseases is still debated. To understand the clinical relevance of autophagy in primary e secondary hepatic tumors, we analyzed the expression of mTOR (mammalian target of rapamycin), a key regulator of autophagy; Raptor (regulatory-associated protein of mTOR); ULK1 (Unc-51 like kinase 1) determinant in the autophagy initiation; LC3 (microtubule-associated protein 1A/1B-light chain 3), a specific marker of autophagosomes; and p62, a selective autophagy receptor. Samples from subjects with chronic hepatitis (n.58), cirrhosis (n.12), hepatocellular carcinoma (HCC, n.56), metastases (n.48) from colorectal cancer and hyperplasia or gallbladder stones (n.7), the latter considered as controls, were examined. Gene expression analysis was carried out in n.213 tissues by absolute q-PCR, while protein expression by Western Blot in n.191 lysates, including tumoral, surrounding tumoral and normal tissues. Nonparametric statistical tests were used for comparing expression levels in the above-mentioned groups. Subgroup analysis was performed considering viral infection and chemotherapy treatment. The mTOR transcriptional level was significantly lower in metastases compared to HCC (P = 0.0001). p-mTOR(Ser2448) and LC3II/LC3I protein levels were significantly higher in metastases compared to HCC (P = 0.008 and P<0.0001, respectively). ULK(Ser757) levels were significantly higher in HCC compared to metastases (P = 0.0002) while the HCV- and HBV- related HCC showed the highest p62 levels. Chemotherapy induced a down-regulation of the p-mTOR(Ser2448) in metastases and in non-tumor surrounding tissues in treated patients compared to untreated (P = 0.001 and P = 0.005, respectively). Conclusions: the different expression of proteins considered, owning their interaction and diverse tissue microenvironment, indicate an impairment of the autophagy flux in primary liver tumors that is critical for the promotion of tumorigenesis process and a coexistence of autophagy inhibition and activation mechanisms in secondary liver tumors. Differences in mTOR and LC3 transcripts emerged in tumor-free tissues, therefore particular attention should be considered in selecting the control group.

Background: Hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC) are the most common primary malignancies of the liver. The combined form of these two tumors (i.e., cHC-CC) is a considerably rare type of liver cancer displaying both malignant components. Methods: In this research, 53 patients were evaluated retrospectively, who had undergone an operation for primary liver tumors in a single tertiary center, in terms of demographics, operation, tumor features, histopathological analysis, and their relationship with survival. Results: The study groups consisted of 20 ( 37.7%) and 33 (62.3%) females and males, respectively, with a mean age of 62.3 years. It was revealed that the survival rate was significantly higher in HCC, compared to other groups (P<0.05). Moreover, alpha-fetoprotein (AFP) was significantly higher in the HCC group than in the ICC group, and carbohydrate antigen 19-9 levels and the presence of jaundice and perineural invasion were significantly higher in the ICC group, compared to HCC patients. In the HCC group, macroscopic vascular invasion, perineural invasion, and T staging were statistically significant. It was also found that in the ICC group, the macroscopic vascular invasion was statistically significant, and in the cHC-ICC group, the increased levels of AFP showed a statistically significant effect on survival (P<0.05). Conclusions: To the best of our knowledge, the current research was one of the very few studies performed focusing on each group of liver tumors in a single study. Based on the findings of this research, there were statistically significant results in all three groups and their comparison with each other.
