Histopathological patterns and immunophenotyping of feline lymphomas and incidence in Metropolitan Bangkok, Thailand.

Background And Aim: Feline lymphomas are categorized based on the location of tumor cells, with anatomical classifications including alimentary, mediastinal, multicentric, and extranodal forms. Accurate diagnosis and classification of feline lymphoma are paramount for enhancing treatment and prognosis. T-cell lymphomas are CD3 positive, while B-cell lymphomas exhibit positive forCD20, CD79α, and paired box 5 (PAX5).

Investigating comparative polymerase chain reaction for antigen receptor rearrangement analysis in different types of feline lymphoma samples.

Cats have the highest incidence of lymphoma among all animal species. Lymphoma accounts for 41% of all malignant tumors in cats and is responsible for 90% of hematopoietic tumors in felines. Biopsies are considered the gold standard for diagnosis.

Post-Chemotherapy Canine Lymphomatous Lymph Node Observations on B-Mode and Strain Elastographic Ultrasound.

Canine multicentric lymphoma (CML) is a prevalent hematopoietic neoplasm that initially responds well to treatment but often relapses due to chemotherapy resistance. Evaluation of treatment response is essential for effective management. Ultrasound (US) can differentiate between benign and lymphomatous lymph nodes (LLNs).

Single nucleotide polymorphism profiles of canine T-cell and null-cell lymphomas.

Background: The histopathological classification of T-cell lymphoma (TCL) in humans has distinctive mutational genotyping that suggests different lymphomagenesis. A similar concept is assumed to be observed in dogs with different TCL phenotypes.

Objective: This study aimed to identify the previously reported single-nucleotide polymorphisms (SNPs) in both human beings and dogs in canine TCLs and null-cell lymphomas (NCLs) and to design compatible oligonucleotides from each variant based on the multiplex polymerase chain reaction.

Hematological and blood biochemistry parameters as prognostic indicators of survival in canine multicentric lymphoma treated with COP and L-COP protocols.

Background And Aim: Hematological and blood chemistry parameters are crucial for evaluating and monitoring canine multicentric lymphoma during chemotherapy. Pre-treatment hematological and blood chemistry parameters can be used as prognostic survival outcomes for this disease. Therefore, this study aimed to investigate the effect of hematological and blood chemistry parameters pre-treatment and 4 weeks post-treatment on the survival outcomes of dogs treated with either a combination of cyclophosphamide, vincristine, and prednisolone (COP) or a combination of COP with L-asparaginase (L-COP) protocols.
