Myxosarcomas are known to be classified as soft tissue sarcomas. However, there is limited clinical characterization pertaining specifically canine cutaneous myxosarcomas in the literature. The objective of this study evaluate local recurrence rate, metastatic rate and prognosis myxosarcoma.A total 32 dogs diagnosed with myxosarcoma via histopathology were included retrospective study. All had surgical resection. No adjunct treatments performed 9 dogs, while 22 also received either radiation...
Abstract Lymphangiosarcomas are uncommon vascular neoplasms that arise from lymphatic endothelial cells (LECs). They efface and replace normal subcutaneous tissue characterised by arborising, channels lined a single layer of pleomorphic paucity erythrocytes. architecturally similar to hemangiosarcomas, common malignancy origin arising blood cells. Common immunohistochemical markers for endothelium, such as Factor VIII ‐related antigen (F8RA) CD31 , have traditionally been used confirm the...
Abstract Lymphangiosarcoma ( LAS ) is an uncommon malignant neoplasia arising from lymphatic endothelium; little information exists regarding therapy. Single institutional retrospective review for canine histopathology diagnoses over a 15‐year period yielded 12 dogs. Ten dogs were presented mass and/or swelling at cervical, trunk or limb regions. Prior to diagnosis, 10 received empiric wound Cytology performed in consisted of mild inflammation. Survival ranged 60, 168 and 876 days three with...
Abstract Diffuse large B‐cell lymphoma (DLBCL) is the most common haematopoietic malignancy in dogs. Recently, MYC and BCL2 expression levels determined with immunohistochemistry (IHC) were found to be prognostic people DLBCL. We hypothesized that canine DLBCL can similarly subdivided into subtypes based on of BCL2. Cases treated CHOP chemotherapy retrospectively collected 43 dogs had available histologic tissue complete clinical follow‐up. Median values percent immunoreactive versus...
Report clinical outcomes of dogs with surgically excised mast cell tumors (MCT) and soft tissue sarcomas (STS).Prospective study.Fifty-three 52 MCT (50 low grade, 2 high grade) 19 STS (12 grade I, 6 II, 1 III).All were examined at 3, 6, 12, 18, 24 months postoperatively, cytologic or histopathologic evaluation suspected local recurrences. Dogs euthanized because study tumor-related causes underwent necropsy.Median intraoperative margins 20 mm 30 wide for STS, respectively, fascial plane...
Abstract Background Dogs with lymphoma that fail cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy (CHOP) before completion of their protocol are commonly thought to have poor long‐term outcome, but no previous studies evaluated the effect early relapse on progression‐free interval (PFI) or overall survival time (OST) for patients undergoing rescue chemotherapy. Objective Correlate treatment outcomes in dogs multicentric after 1st‐line CHOP Methods Data were collected...
Abstract Background B‐cell chronic lymphocytic leukemia (BCLL) in dogs generally is considered an indolent disease, but previous studies indicate a wide range survival times. Objectives We hypothesized that BCLL has heterogeneous clinical course, similar to humans. aimed assess presentation and outcome with evaluate the prognostic relevance of flow cytometric factors. Animals One hundred twenty‐one diagnosed by cytometry. Three breed groups were represented: small (n = 55) because increased...
A doxorubicin (DOX)-based chemotherapy protocol, CHOP, is the most effective treatment for canine high-grade B-cell lymphoma; however, cost and time requirements associated with this protocol are not feasible many pet owners. An alternative option use of DOX, drug, in combination prednisone. Prior studies single-agent DOX included dogs T-cell lymphoma, a known negative prognostic factor, which may have resulted shorter reported survival times than if lymphoma were analyzed separately. The...

The role of epigenetic alterations during cancer has gained increasing attention and resulted in a paradigm shift our understanding mechanisms leading to susceptibility. Sulforaphane (SFN) is naturally occurring isothiocyanate derived from the precursor glucosinolate, glucoraphanin (GFN), which found cruciferous vegetables such as broccoli. been shown suppress tumour growth by several including inhibiting histone deacetylases. objective this study was provide detailed analysis sulforaphane...
While current lymphoma therapies induce remission in most dogs, drug-resistant relapse is common, creating a need for novel agents. Rabacfosadine (RAB), double prodrug of the acyclic nucleotide phosphonate 9-(2-phosphonylmethoxyethel) guanine (PMEG), preferentially targets cells with reduced systemic toxicity compared PMEG. Previous studies evaluating RAB administered every 21 days have suggested efficacy both naïve and relapsed subjects; however, no large as single agent been reported...
