CHOP-based (cyclophosphamide, doxorubicin, vinca alkaloid, prednisolone) chemotherapy protocols are often recommended for treatment of feline lymphoma. While maintenance-free have been published and readily used in dogs, there is limited literature regarding similar cats. The purpose this study was to describe the outcome cats with intermediate- high-grade lymphoma that were prescribed a modified 25-week University Wisconsin-Madison (UW-25) protocol. A secondary objective examination...

Objectives To report the clinical presentation, treatment and prognosis of dogs with low‐grade gastrointestinal lymphoma. Materials Methods Cases were solicited from American College Veterinary Internal Medicine Oncology Diplomate listserv. Medical records lymphoma diagnosed via a combination histology immunohistochemistry or without analysis polymerase chain reaction for antigen receptor rearrangement included. Signalment, signs, diagnostic test results, chemotherapy protocol, response to...

Dogs with B-cell lymphoma typically respond well to first-line CHOP-based chemotherapy, but there is no standard of care for relapsed patients. To help veterinary oncologists select effective drugs dogs lymphoid malignancies such as lymphoma, we have developed multimodal machine learning models that integrate data from multiple tumor profiling modalities and predict the likelihood a positive clinical response 10 commonly used chemotherapy drugs. Here report on outcomes occurred after...

Objectives The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) categorizes fine needle aspiration and cytology (FNAC) results into 6 tiers assigns a risk of malignancy (ROM) to each category. Its utility in submandibular gland lesions remains unclear. Our article aims study (1) the MSRSGC classifying FNAC masses, (2) describe demographics incidence our population, (3) analyze accuracy diagnosis benign malignant tumors. Methods In this retrospective case series, 92 patients...

Previously reported radiation protocols for transitional cell carcinoma of the canine lower urinary tract have been ineffective or associated with increased side effects. Objectives this retrospective, cross‐sectional study were to describe safety and tumor responses a novel palliative protocol in dogs. Included dogs had cytologically histologically confirmed bladder urethra, treated 10 once‐daily fractions (Monday–Friday) 2.7 Gy. Thirteen sampled, six using as first‐line (induction) therapy...

Abstract The vision of a precision medicine–guided approach to novel cancer drug development is challenged by high intratumor heterogeneity and interpatient diversity. This complexity rarely modeled accurately during preclinical development, hampering predictions clinical efficacy. To address this issue, we developed Comparative In Vivo Oncology (CIVO) arrayed microinjection technology test tumor responsiveness simultaneous microdoses multiple drugs directly in patient's tumor. Here, study...

Clinical studies have demonstrated that age 50 years or older is an independent risk factor associated with poor prognosis after burn injury, the second leading cause of traumatic injuries in aged population. While mechanisms driving age-dependent postburn mortality are perplexing, changes intestinal microbiome, may contribute to heightened, dysregulated systemic response seen aging patients. The fecal microbiome from 22 patients admitted a verified center July 2018 February 2019 was...

Feline lymphoma, a prevalent cancer in cats, exhibits varied prognoses influenced by anatomical site and cellular characteristics. In this study, we investigated the utility of flow cytometry clonality analysis via PCR for antigen receptor rearrangement (PARR) with respect to characterizing disease predicting prognosis. For purpose, received fine needle aspirates and/or blood from 438 feline patients, which were subjected PARR. We used subset results patients confirmed B- or T-cell lymphomas...

Background: Optimizing nutrition is essential for recovery after major surgery or severe illness. Feeding tubes (FT) can be placed in patients limited by oral enteral nutrition. Given the myriad of locations which these procedures are performed (radiology, intensive care unit, and endoscopy suite), routine follow-up challenging. The purpose this study was to evaluate impact an FT clinic on We hypothesized that enrollment would result improved nutritional outcomes. Methods: Retrospective...
