Abstract
New knowledge and data can influence the treatment options of dogs and cats affected by neoplasms. Partial limb amputation with the use of a prosthesis is possible in dogs. Newer studies attempt to define better and understand the complications and limb function associated with this approach. Limb sparing is an alternative to amputation, and three-dimensional printing allows the manufacturing of personalized endoprostheses. Finally, the recommended approach for the excision of cutaneous mast cell tumors (MCTs) is with proportional margins. In dogs, grade shifting might have occurred when removing a recurrent MCT or soft tissue sarcoma.

Abstract
The combined treatment of electrochemotherapy (ECT) and interleukin-12 (IL-12) gene electrotransfer (GET) has already been used in clinical studies in dogs to treat various histological types of spontaneous tumors. The results of these studies show that the treatment is safe and effective. However, in these clinical studies, the routes of administration of IL-12 GET were either intratumoral (i.t.) or peritumoral (peri.t.). Therefore, the objective of this clinical trial was to compare the two IL-12 GET routes of administration in combination with ECT and their contribution to the enhanced ECT response. Seventy-seven dogs with spontaneous mast cell tumors (MCTs) were divided into three groups: one treated with a combination of ECT + GET peri. t. (29 dogs), the second with the combination of ECT + GET i.t. (30 dogs), and the third with ECT alone (18 dogs). In addition, immunohistochemical studies of tumor samples before treatment and flow cytometry of peripheral blood mononuclear cells (PBMCs) before and after treatment were performed to determine any immunological aspects of the treatment. The results showed that local tumor control was significantly better in the ECT + GET i.t. group (p < 0.050) than in the ECT + GET peri.t. or ECT groups. In addition, disease-free interval (DFI) and progression-free survival (PFS) were significantly longer in the ECT + GET i.t. group than in the other two groups (p < 0.050). The data on local tumor response, DFI, and PFS were consistent with immunological tests, as we detected an increased percentage of antitumor immune cells in the blood after treatment in the ECT + GET i.t. group, which also indicated the induction of a systemic immune response. In addition, we did not observe any unwanted severe or long-lasting side effects. Finally, due to the more pronounced local response after ECT + GET i.t., we suggest that treatment response assessment should be performed at least two months after treatment, which meets the iRECIST criteria.

Abstract
Cutaneous canine mast cell tumors (ccMCTs) vary in their biological behavior, treatment, and prognosis, based on their grade. Immune cell infiltration has been associated with prognosis and response to treatments in some human cancers, and immune-targeting therapeutics are increasingly being explored in veterinary oncology. However, currently little is known about the tumor microenvironment (TME) in ccMCTs. Therefore, the objective of this study was to determine the prevalence of T lymphocytes, T regulatory lymphocytes, PD-1+ cells and macrophages in low- and high-grade ccMCTs. Thirty low-grade and 20 high-grade formalin-fixed paraffin-embedded ccMCT samples were included. Immunohistochemistry (IHC) was performed to detect CD3, FOXP3, Iba1, and PD-1 on sequential sections. Three 400x fields with the highest numbers of CD3+ cells were identified for each tumor. The percentage of CD3+, FOXP3+, and Iba1+ cells, and the number of PD-1+ cells, was quantified in each of these three "hot-spot" fields using ImageJ software. Iba1 expression was significantly greater in high-grade compared to low-grade ccMCTs (mean = 12.5% vs. 9.6%, p = 0.043). PD-1 expression was low overall, but a significantly higher number of PD-1-expressing cells was observed in high-grade ccMCTs (median 1 vs. 0, p = 0.001). No significant difference was noted in CD3 and FOXP3 expression between ccMCT grades. Macrophages and PD-1+ cells were more frequent in high-grade, compared to low-grade ccMCTs. Further studies are needed to define the role of macrophages and rare PD-1+ cells in high-grade ccMCTs.

Abstract
Cannabinoid receptors (CB1 and CB2) belong to endocannabinoid system (ECS), which is also composed from endocannabinoids and the enzymatic systems involved in their biosynthesis and degradation. The expression of CB1 and CB2 have been previously identified in normal canine mast cell and in atopic dermatitis. Canine cutaneous mast cell tumours (cMCTs) are among the most common cutaneous neoplasms in dogs and have a highly variable clinical behaviour. Expression of CB1-CB2 was assessed by means of immunohistochemistry in thirty-seven dogs (from 2019 to 2021) with proven histological diagnosis of cMCT. Dogs were divided in two groups according to the Kiupel's grading system: high-grade (HG) cMCT and low-grade (LG) cMCT. A semiquantitative (score 0-3) and quantitative assessment of immunoreactivity (IR) was performed for each case. Our results show that there CB1 and CB2 are highly expressed in LG- cMCT, in contrast to HG- cMCT.

Abstract
BACKGROUND While lymphadenectomy of metastatic lymph nodes (LNs) has been associated with improved outcome, the clinical utility of prophylactic lymphadenectomy in dogs with stage I cutaneous mast cell tumors (cMCTs) remains a controversial topic. To assess the therapeutic role of lymphadenectomy of uninvolved regional LNs, the long-term outcome of cMCT-bearing dogs with cytologically negative and surgically unresected regional LNs (observation only, OO) was compared with that of dogs with surgically resected and histologically negative regional LNs (prophylactic regional lymphadenectomy, PRL). RESULTS A retrospective analysis of 64 dogs with a low-grade, completely resected stage I cMCT was performed: 35 (54.7%) dogs were subjected to OO and 29 (45.3%) underwent PRL. Dogs were monitored for a median of 813 and 763 days in the OO group and PRL group, respectively. The number of dogs undergoing MCT progression was significantly higher in the OO group (P = 0.028) and curve comparison revealed a tendency to a better time to progression in the PRL group (P = 0.058). No significant difference in survival time (P = 0.294) was observed between dogs in the OO and PRL groups. CONCLUSIONS Our results showed that lack of immediate lymphadenectomy was associated with a higher risk for tumor progression. This preliminary judgement, reinforced by the findings that lymphadenectomy was well tolerated in all cases, and that histopathology provides the definitive assessment of the nodal pathological status, may suggest that prophylactic lymphadenectomy is indicated in the management of stage I MCTs. Larger prospective studies are warranted for generating clinical evidence of this latter hypothesis.

Abstract
INTRODUCTION Synchronous primary tumors are considered severe, comorbid conditions in people representing neoplasm that develop independently and concomitantly. A diagnosis of synchronous tumors was made in a dog, underlying the difficulties to reach it without the aid of multiple diagnostic techniques aimed to demonstrate the simultaneous coexistence of different tumor types. MATERIALS AND METHODS A 7-year-old male Boxer dog presented several tumors located on the skin of the left hind limb and the scrotal region. Moreover, additional tumors in the testicles, after palpation and ultrasound examination, were detected. Following diagnostic results, the cutaneous tumor, scrotum, and testes were surgically removed. RESULTS Pathological investigations revealed the presence of five different tumors: a cutaneous mast cell tumor; a scrotal melanocytoma; three testicular neoplasms (Sertoli Sustentacular cell tumor, seminoma, and interstitial Leydig cell tumor). CONCLUSIONS The present report describes a neoplastic synchronism due to the presence of five different primary tumors in a dog and, for the first time the presence of a collision testicular tumor together with other non-testicular primary tumors. The occasional finding underlines the importance of the knowledge of such conditions in the process of decision-making and in carrying out all the proper diagnostic procedures for a correct diagnosis and clinical staging.

Abstract
Background Nephrotic syndrome (NS) is rare in dogs and is characterized by concurrent clinical findings of proteinuria, hyperlipidemia, hypoalbuminemia, and edema. NS has been reported in humans receiving tyrosine kinase inhibitors (TKI) and in dogs receiving masitinib. This is the first report of NS in a dog receiving toceranib phosphate. Case presentation An 8-year-old, female, spayed Labrador retriever was diagnosed with a 10 cm mast cell tumor on the left lateral abdomen. After completion of a 12-week vinblastine and prednisone protocol, she began treatment with toceranib phosphate (2.6 mg/kg by mouth, every other day). Proteinuria was documented prior to starting toceranib. On day 426 after diagnosis (day 328 of toceranib phosphate treatment), the dog was evaluated for diarrhea, lethargy and anorexia. On physical examination, dependent edema was noted on the ventral chest and abdomen, and sterile neutrophilic inflammation was aspirated from a 2.3 cm splenic nodule. The following laboratory values were reported: albumin < 1.5 g/dL; cholesterol 378 mg/dl and urine protein to creatinine ratio of 3.79. The patient was diagnosed with NS, and treatment with toceranib phosphate was discontinued. Low-dose aspirin was started in addition to an increased dosage of enalapril (0.47 mg/kg q12hr). No other therapy was instituted. The dog improved clinically, and laboratory values returned to near normal over the 8-week follow-up. She was euthanized 1399 days after discontinuing toceranib phosphate with progressive disease. Conclusions Nephrotic syndrome is a potential adverse event associated with the drug toceranib phosphate which may be reversible with discontinuation of treatment. Careful monitoring of urine protein, serum biochemistry, blood pressure and patient weight is advisable during treatment with toceranib phosphate.

Abstract
Mast cell tumor (MCT) has long been considered as an uncommon neoplasm in horses. Cytological and behavioral evidence of its malignancy is usually lacking, and only a few reports have described MCT displaying malignant behavior. An 18-year-old Friesian stallion presented with a one-year history of intermittent and progressive skin lesions on the left forelimb associated with intense, generalized pruritus and apathy temporarily responsive to glucocorticoids and antibiotics. The horse was alert and responsive with poor body condition and marked generalized pruritus. The left forelimb was markedly enlarged and surrounded by numerous firm 2- to 20-cm masses that were ulcerated and focally necrotic. A 7-cm round firm mass was observed on the left dorsal neck. Dermatological examination revealed generalized moth-eaten alopecia and scaling with erosions and ulcers secondary to pruritus. A direct skin smear from the affected leg showed severe eosinophilic inflammation and neutrophilic inflammation with pleomorphic bacteria. Histopathology of the skin and biopsies of the underlying tissues revealed an abundant population of atypical mast cells consistent with a malignant MCT. The horse was euthanized and necropsy revealed a marked fibrous reaction on longitudinal sections of the affected limb, and the tumor could be detected on only a few histological slides. Diagnosis of equine MCT can be challenging because of the massive accompanying fibrous reaction. Mast cell tumor should be suspected in the presence of eosinophilic infiltration of the affected tissue and in cases of generalized pruritus not attributable to other causes.

Abstract
Background Traditionally, wide lateral surgical margins of 3 cm and one fascial plane deep have been recommended for resection of canine cutaneous mast cell tumor (MCT). Several studies have been published assessing surgical margins of less than this traditional recommendation. The objective of this systematic review was to determine if resection MCT with lateral surgical margins < 3 cm results in low rates of incomplete resection and local tumor recurrence. Systematic searches of digital bibliographic databases were performed with two authors (AR & LES) screening abstracts to identify relevant scientific articles. Studies regarding surgical treatment of dogs with cutaneous MCT were reviewed. Data abstraction was performed and the quality of individual studies and the strength of the body of evidence for utilization of surgical margins < 3 cm for removal of MCTs was assessed. Results From the initial 78 citations identified through the database searches, four articles were retained for data abstraction after both relevance screenings were performed. Two studies were retrospective observational studies, one was a prospective case series and one was a prospective clinical trial. Assessment of the quality level of the body of evidence identified using the GRADE system was low. Excision of MCT at 2 cm and 3 cm was associated with comparably low rates of incomplete excision and recurrence. Conclusions Despite the low quality of the overall body of evidence, a recommendation can be made that resection of canine cutaneous MCTs (< 4 cm) of Patnaik grade I and II with 2 cm lateral margins and 1 fascial plane deep results in low rates of incomplete excision and local tumor recurrence.

Abstract
The concentration of circulating heat shock protein 70 (Hsp70) was measured in liquid biopsies of canine tumor patients as a potential biomarker. Compared with rodent tumor models, spontaneously occurring tumors in pet dogs reflect the clinical situation of human patients better, as dogs cohabitate with their owners in the same environment, reach a much older age than rodents, can provide blood samples much more frequently, and receive up-to-date medical care and, similar to humans, their tumors show a high genetic heterogeneity. Due to the species-specific sequence homology of human and canine Hsp70, two human enzyme-linked immunosorbent assay (ELISA) systems (R&D and lipHsp70) were used to measure canine Hsp70 concentrations in serum and plasma. In general, higher Hsp70 concentrations were found in serum compared with plasma samples of dogs, and the lipHsp70 ELISA detected higher peak concentrations of Hsp70 in a broader range than the R&D ELISA. Compared with a tumor-free control group, serum Hsp70 concentrations were higher in tumor-bearing dogs, irrespective of breed, age, body weight, and gender. A sub-classification of the different tumors according to their cytological characteristics revealed significantly elevated Hsp70 serum concentrations in dogs with round cell tumors (p < 0.01), a heterogeneous group of malignancies with hematopoietic origin such as mast cells, plasma cells, lymphocytes, histiocytes, and melanomas. Future studies with larger patient cohorts and well-defined tumor sizes are necessary to elucidate the role of serum Hsp70 as a biomarker for tumor detection and monitoring of outcome in pet animals.

Abstract
Although reovirus has reached phase II and III clinical trials in human cancers, the exact mechanism of reovirus oncolysis is still not completely understood. Previously, we have shown that canine mast cell tumor (MCT) cell lines were highly susceptible to reovirus, as compared with other kinds of canine cancer cell lines. In this study, we showed that reovirus infection not only led to the dephosphorylation but also downregulation of c-kit in four canine MCT cell lines, where c-kit activation is required for proliferation. Consistent with c-kit dysregulation, downstream signaling of c-kit, the level of Ras-GTP and phosphorylation of all the downstream effectors of Ras (Raf, MEK, and ERK) and Akt decreased in all the cell lines after reovirus infection, except for Akt in one of cell lines. Pro-apoptotic and anti-apoptotic proteins such as Bim, Bad and Mcl-1 were also altered by reovirus infection in these cell lines. In short, reovirus infection degraded c-kit in all the canine MCT cell lines, leading to the downregulation of downstream signaling of c-kit, which may relate to the cell death induced by reovirus.

Abstract
Canine cutaneous mast cell tumors (MCTs) are among the most common canine cutaneous tumors, with highly variable biological behavior. This review describes in detail current approaches for cytologic and histologic diagnosis and prognosis, including advantages and limitations of cytologic and histologic grading and utilization of molecular markers, for example, Ki67, AgNORs, KIT expression, and c-Kit mutations, for a more accurate detection of aggressive MCTs. Furthermore, the current approach to evaluate surgical margins and spread to local lymph nodes is discussed.

Abstract
Tumor microenvironment represents a key obstacle for the effectiveness of anticancer drugs. Electrochemotherapy involves the systemic or local delivery of lipophobic drugs such as bleomycin and cisplatin, with the application of permeabilizing electric pulses having appropriate amplitude and waveforms. This greatly enhances the uptake of these drugs by an estimated factor of 700-fold for bleomycin and 4 to 8 times for cisplatin. Because of its efficacy and limited morbidity, this therapeutic option is becoming more and more available in veterinary oncology either as an adjuvant to surgery or as first line of treatment with palliative or curative purposes.

Abstract
Mast cell tumors are the most common malignant cutaneous tumors in dogs. Although there are several prognostic factors involved, the clinical and biological behavior of this type of tumor varies greatly, making the best choice of treatment challenging. Molecular techniques can be used to evaluate a large number of genes involved in the neoplastic process and aid in the selection of candidate genes related to prognostic and predicting factors. Identification of the genes associated with tumor development and progression can be performed through the analysis of numerical and structural changes in DNA isolated from tumor cells by array comparative genomic hybridization (aCGH). The aim of this study was to compare copy number variations (CNVs) in cutaneous mast cell tumors of dogs that survived less than six (ST<6) and >12months (ST>12) from the date of diagnosis. Ten animals were used: four from Group ST>12 and six from Group ST<6. Genomic DNA was extracted, and aCGH was performed using Agilent Canine Genome CGH Microarray 4×180 (ID-252 552 - Agilent, USA). Data analysis was carried out using Nexus program version 5.0 (Biodiscovery, USA). The group ST>12 presented 11±3.3 CNVs, while the ST<6 group presented 85±38.5 CNVs. Regions of loss in PTEN and FAS as well as regions of gains in MAPK3, WNT5B, FGF, FOXM1 and RAD51 were detected in mast cell tumors with shorter survival times, and thus, worst prognoses, allowing for the identification of potential candidate genes for more detailed studies.

Abstract
The histopathological, immunohistochemical, and ultrastructural morphologic characteristics of a tumor in the subcutaneous tissue of the chest of a 19-year-old female Japanese macaque were investigated. Consequently, the mass was diagnosed as a malignant mast cell tumor (MCT). Tumors were present in both mammary gland portions of the anterior thorax. Both tumors showed the same histopathological findings. The tumor tissue was defined by the presence of delicate connective tissue, and the tumor cells grew in a cord-like or cobblestone pattern. The tumor cell cytoplasm was very clear. The nuclei were relatively uniform and the cells showed a low nucleus-cytoplasm ratio. The cytoplasmic granules stained blue with Alcian blue and eosinophils had infiltrated into the tumor tissue. Furthermore, immunohistochemical analysis revealed that the tumor cell membrane was positive for the anti-c-kit antibody. In ultrastructural morphologic analyses, all tumor cells showed a rich cytoplasm and, occasionally, granules wrapped in a limiting membrane of high electron density. The tumor cells had metastasized to the axillary lymph nodes, the kidney, and the peritoneum. Based on these results, the mass was diagnosed as a malignant MCT originating from the subcutaneous tissue of the chest. Since cases of MCTs in macaques are very rare, this report presents important new knowledge of neoplastic lesions in this species.

Abstract
In view of the varied biologic behavior and the costs of treatment for canine cutaneous mast cell tumors, development of appropriate treatment plans for individual affected dogs can be difficult, but decisions regarding treatment should be made using a systematic, evidence-based approach. This manuscript reviews the current state of diagnostics and prognostication of canine cutaneous mast cell tumors, and suggests a combined approach based on clinical and pathologic assessment for decision making regarding treatment choices. The current state of histologic grading, evaluation of proliferation indices, evaluation of mutations in the c-kit gene and KIT expression, evaluation of excision and clinical staging are examined. On the basis of the current understanding of prognostication and treatment response, algorithms for selection of local and systemic therapy are presented.

Abstract
Cutaneous mast cell tumors (MCTs) are among the most frequent malignant tumors in dogs and Boxer breed dogs have a higher incidence of this disease. Ki67 staining and KIT staining are widely used to predict natural behavior in canine MCT but no previous study has evaluated double staining of these proteins as a prognostic factor. Based on biological behavior predictors in canine MCT, the purpose of this study was to determine the Ki67 proliferative index in KIT positive cells using double stain immunohistochemistry technique. Sixty-nine MCTs from Boxer dogs were selected and a tissue microarray was constructed for the double stained immunohistochemistry. Double positivity (Ki67(+)/KIT(+)) was observed in 20/69 (29%) MCT, with a mean of 9.06 double positive cells per tissue core (range 0.48%-43.97%) and Ki67(-)/KIT(+) animals had a longer survival time than Ki67(+)/KIT(+) animals (p=0.03).
