Abstact (Conclusions and Clinical Relevance)
Advanced carcinomas in dogs present significant therapeutic challenges with limited treatment options and poor prognoses. Sorafenib, a multi-kinase inhibitor targeting RAF and receptor tyrosine kinases, has demonstrated antitumor activity and tolerability in preclinical veterinary studies; however, clinical data remain limited. Sorafenib was well tolerated and provided measurable clinical benefit in dogs with advanced carcinomas. Lameness may represent a prognostic biomarker, and weight gain may reflect a favourable clinical response. These findings support further investigation of sorafenib and other tyrosine kinase inhibitors in veterinary oncology.
