Abstract
Background Hepatocellular carcinoma (HCC) is the most common malignant liver tumor in dogs. Although surgical resection is a major treatment option for canine HCC, there are no distinct strategies for unresectable tumor subtypes or adjuvant chemotherapy for tumors with positive margins. We aimed to establish and characterize novel HCC cell lines from canine patients. Methods The cellular morphology, general growth features and tumorigenicity of the established cell lines were evaluated. We also examined the sensitivity of the cell lines to multi-target tyrosine kinase inhibitors (TKIs). Results We established novel canine HCC cell lines from hepatic tumors and an additional kidney tumor of six canine patients. All cell lines showed colony forming and migratory ability. KU-cHCC-001 and KU-cHCC-001-Kidney, two cell lines exhibiting high epithelial-mesenchymal transition characteristics, showed tumorigenicity in xenografted mice. Toceranib, a veterinary TKI that targets vascular endothelial growth factor (VEGFR)/platelet-derived growth factor receptor (PDGFR)/c-kit, effectively inhibited the mitogen-activated protein kinase pathway and induced apoptosis. The established canine HCC cell lines showed greater sensitivity to toceranib than to sorafenib, a first-line treatment for human HCC targeting RAF/VEGFR/PDGFR. Sorafenib showed improved anti-tumor effects when co-treated with SCH772984, an extracellular signal-regulated kinase inhibitor. Conclusion Our study suggests new therapeutic strategies for canine HCC, and these cell lines are valuable research materials for understanding HCC tumor biology in both humans and dogs.

Abstract
BACKGROUND Canine hepatocellular tumours (HCTs) are common primary liver tumours. However, the exact mechanisms of tumourigenesis remain unclear. Although some genetic mutations have been reported, DNA methylation alterations in canine HCT have not been well studied. OBJECTIVES In this study, we aimed to analyse the DNA methylation status of canine HCT. METHODS Tissues from 33 hepatocellular carcinomas, 3 hepatocellular adenomas, 1 nodular hyperplasia, 21 non-tumour livers from the patients and normal livers from 5 healthy dogs were used. We analysed the DNA methylation levels of 72,367 cytosine-guanine dinucleotides (CpG sites) in all 63 samples. RESULTS AND CONCLUSIONS Although a large fraction of CpG sites that were highly methylated in the normal liver became hypomethylated in tumours from most patients, we also found some patients with less remarkable change or no change in DNA methylation. Hierarchical clustering analysis revealed that 32 of 37 tumour samples differed from normal livers, although the remaining 5 tumour livers fell into the same cluster as normal livers. In addition, the number of hypermethylated genes in tumour livers varied among tumour cases, suggesting various DNA methylation patterns in different tumour groups. However, patient and clinical parameters, such as age, were not associated with DNA methylation status. In conclusion, we found that HCTs undergo aberrant and diverse patterns of genome-wide DNA methylation compared with normal liver tissue, suggesting a complex epigenetic mechanism in canine HCT.

Abstract
The Wildlife Conservation Society (WCS) has housed fennec foxes (Vulpes zerda) at its facilities since the early 1900s and currently has one of the largest populations managed by the fennec fox Species Survival Plan. Of the 83 foxes held by WCS institutions between 1980 and 2019, 52 medical records and 48 postmortem reports were available for review. Common causes of morbidity included trauma and dermatologic disease, especially atopic dermatitis. Average age at death for animals surviving past 10 wk was 9.76 yr. Common causes of death or euthanasia were neoplasia (15/48, 31%) and infectious disease (14/48, 29%), with neoplastic processes incidentally identified in an additional seven animals. Significant antemortem cardiac changes were identified in 22 animals. Hepatocellular carcinoma (HCC) was diagnosed in nine animals, consistent with previous documentation of HCC as one of the most common neoplasms in this species. Four animals were suspected to have succumbed to vaccine-induced canine distemper virus after receiving a modified live vaccine. No canine distemper infections have been documented after 1981 in this population and since the use of a canarypox-vectored recombinant vaccine. Recommendations for management of this species include routine screening for hepatic neoplasia in adult animals, regular cardiac evaluations including electrocardiogram, echocardiogram, and dermatologic examination as described by the current consensus statement on canine atopic dermatitis. This descriptive morbidity and mortality report is the first for the fennec fox.

Abstract
OBJECTIVE To describe the distribution of histopathologic diagnoses in a large population of dogs undergoing surgical treatment for spontaneous hemoperitoneum secondary to a ruptured liver mass. Additionally, to describe survival outcomes and assess for prognostic factors for overall survival time in this population. ANIMALS 200 client-owned dogs with spontaneous hemoperitoneum resulting from a liver mass. PROCEDURES Medical records from 19 veterinary referral hospitals were reviewed. Data collected included signalment, clinical signs, blood work, radiographic and ultrasonographic findings, surgical methods, intraoperative and postoperative complications, outcomes, and histopathologic findings. Follow-up information was obtained by contacting the referring veterinarian or owner. RESULTS Well-differentiated hepatocellular carcinoma, benign masses, hemangiosarcoma, and other malignant tumors accounted for 36% (72/200), 27.5% (55/200), 25.5% (51/200), and 11% (22/200) of cases, respectively. Overall survival time for all dogs was 356 days and for the above categories was 897 days, 905 days, 45 days, and 109 days, respectively. Prognostic factors for survival included diagnosis, increased ALT, anemia, and whether a transfusion was received. Overall survival time in dogs with increased ALT was 644 versus 63 days with normal values. CLINICAL RELEVANCE The majority of dogs (63.5%) were diagnosed with well-differentiated hepatocellular carcinoma or a benign process, resulting in favorable long-term survival. The distribution of histopathology for ruptured liver masses resulting in hemoperitoneum has not been previously reported and may be useful for client discussions prior to surgery.

Serum steroid profiling of hepatocellular carcinoma associated with hyperadrenocorticism in dogs: A preliminary study. Front Vet Sci 2022; 9:1014792.

Abstract
Background Hepatocellular carcinoma (HCC) is one of the most common primary liver tumors in humans and dogs. Excessive adrenocortical hormone exposure may cause steroid hepatopathy, which may develop into HCC. In our previous study, hyperadrenocorticism (HAC) was a highly concurrent disease in dogs with HCC. Therefore, this study hypothesized that adrenal steroid alterations might be involved in hepatocarcinogenesis and aimed to specify the relationship between HAC and HCC in dogs. Materials and methods This study included 46 dogs brought to the Hokkaido University Veterinary Teaching Hospital between March 2019 and December 2020. Owners gave their signed consent for blood collection on their first visit. A total of 19 steroids (14 steroids and 5 metabolites) in the baseline serum of 15 dogs with HCC, 15 dogs with HAC, and 10 dogs with both diseases were quantitatively measured using the developed liquid chromatography coupled with tandem mass spectrometry (LC/MS/MS) method. Results In each group, 11 steroids were detected higher than 50%. The detection rate of steroid hormones did not significantly differ between the groups (p > 0.05). Principle component analysis (PCA) showed that the steroid profiles of the three groups were comparable. Median steroid hormone concentrations were not significantly different between the study diseases (p > 0.05). Conclusion The developed LC/MS/MS was useful for measuring steroid hormones. Although it was clear that HAC was concurrent in dogs with HCC, none of the serum steroids was suggested to be involved in HCC.

Abstract
Objective To determine and compare median sternotomy (MS) closure‐related complication rates using orthopedic wire or suture in dogs. Study design Multi‐institutional, retrospective observational study with treatment effect analysis. Animals 331 client‐owned dogs, of which 68 were excluded. Methods Medical records of dogs with MS were examined across nine referral centers (2004–2020). Signalment, weight, clinical presentation, surgical details, complications, and outcomes were recorded. Follow‐up was performed using patient records and email/telephone contact. Descriptive statistics, treatment effect analysis and logistic regression were performed. Results Median sternotomy closure was performed with wire in 115 dogs and suture in 148. Thirty‐seven dogs experienced closure‐related complications (14.1%), 20 in the wire group and 17 in the suture group. Twenty‐three were listed as mild, four as moderate and 10 as severe. Treatment effect analysis showed a mean of 2.3% reduction in closure‐related complications associated with using suture versus wire (95% CI: −9.1% to +4.5%). In multivariable logistic regression, the only factor associated with increased risk of closure‐related complications was dog size (p = .01). This effect was not modified by the type of closure used (interaction term: OR = 0.99 [95% CI: 0.96/1.01]). Conclusion The incidence of closure‐related complication after MS was low compared to previous reports. The likelihood of developing a closure‐related complication was equivalent between sutures and wires, independent of dog size, despite a higher proportion of complications seen in larger dogs (≥20 kg). Clinical significance Use of either orthopedic wire or suture appear to be an appropriate closure method for sternotomy in dogs of any size.

Abstract
Local recurrence after surgical excision of canine massive hepatocellular carcinoma (HCC) has been poorly studied in veterinary medicine with scant information published regarding risk factors for and outcome following recurrence. The aim of this case-control study was to describe the time to recurrence, evaluate potential risk factors for recurrence, and report the outcome in dogs with massive HCC. Medical records for 75 dogs who developed recurrence and 113 dogs who did not develop recurrence were reviewed. Statistical analyses were performed to determine risk factors for recurrence as well as the median time to develop recurrence and overall survival time (OS). None of the risk factors evaluated were significant for the development of recurrence. The median time to develop recurrence was 367 days (range: 32-2096 days). There was no significant difference in median OS for dogs who developed recurrence vs. those who did not (851 vs. 970 days). For dogs with recurrent HCC, treatment at recurrence trended toward prolonged OS but was not significantly different from dogs not undergoing treatment at recurrence. There was no significant difference in median OS for dogs with histologically complete vs. incomplete tumor excision (990 vs. 903 days). Though specific risk factors for recurrence were not identified, elevations in liver values were noted in patients with recurrent disease and could act as a noninvasive surveillance tool. Recurrence was noted earlier in dogs who had routine post-operative surveillance (228 vs. 367 days). Routine surveillance for recurrence is recommended especially in dogs where further intervention is possible and should extend beyond 1 year. Patients with massive HCC have a good long-term prognosis regardless of incomplete excision, pulmonary metastasis, or recurrent local disease. This article is protected by copyright.

Abstract
OBJECTIVES Canine hepatobiliary disease is common; however, data determining disease frequency and breed predispositions are lacking. The primary objective was to identify the frequency of different hepatobiliary disease in a United Kingdom population of dogs and consequently determine breeds at both an increased and decreased risk of hepatobiliary disease. MATERIALS AND METHODS Anonymised histopathology reports from a commercial veterinary diagnostic laboratory, which were submitted between August 2013 and February 2018, were analysed. Data were retrospectively categorised into hepatobiliary diseases according to World Small Animal Veterinary Association Standards and the breed, age and genders recorded. Cases with incomplete data or no definitive diagnosis were excluded. Breed predisposition was calculated using odds ratios and 95% confidence intervals against a United Kingdom-based control population of micro-chipped dogs. RESULTS Histopathology results from 4584 cases met inclusion criteria. The most frequent histological diagnoses were reactive hepatitis (n=770); chronic hepatitis (n=735) and reversible hepatocellular injury (n=589). A number of breeds were shown to be at an increased or decreased risk of individual liver diseases. CLINICAL SIGNIFICANCE This is the first study to document the histopathological frequency of hepatobiliary diseases in a large cohort of dogs in the United Kingdom, as well as novel possible breed and age predispositions. Despite multivariable analysis not being performed to account for confounding factors, this information hopes to inform and support future investigations for hepatic disease in particular breeds and potential predispositions.
