Summary
Alpha-fetoprotein (AFP) levels are higher in dogs with multicentric lymphoma, particularly in advanced stages. Chemotherapy reduces AFP concentrations, suggesting its use as a lymphoma biomarker.
Area of Science:
- Veterinary Oncology
- Biochemistry
Background:
- Alpha-fetoprotein (AFP) is a protein with established roles in fetal development.
- Elevated AFP levels in canines have been anecdotally linked to certain neoplastic conditions.
Purpose of the Study:
- To investigate the diagnostic and prognostic value of serum AFP concentrations in dogs with multicentric lymphoma.
- To assess the impact of chemotherapy on AFP levels in lymphoma-affected dogs.
Main Methods:
- Serum samples were collected from healthy dogs and dogs diagnosed with multicentric lymphoma.
- AFP concentrations were measured before and during chemotherapy treatment (induction and maintenance phases).
- Statistical analysis compared AFP levels between healthy controls and lymphoma groups, and across different lymphoma stages and treatment phases.
Main Results:
- Dogs with multicentric lymphoma exhibited significantly higher serum AFP concentrations compared to healthy controls.
- AFP levels were highest in dogs with advanced-stage (Stage V) lymphoma.
- Chemotherapy treatment led to a significant decrease in serum AFP concentrations during both induction and maintenance phases.
Conclusions:
- Serum AFP concentration can serve as a valuable biomarker for staging canine multicentric lymphoma.
- Monitoring AFP levels may aid in assessing treatment response and the extent of neoplastic infiltration, particularly in the liver.
- AFP determination offers a potential additional tool for evaluating lymphoma progression and therapeutic efficacy in dogs.
