What to know about Existing drug could treat invasive canine oral tumors

Researchers at Cornell University have developed a diagnostic tool to distinguish between two types of canine oral tumors, Canine Acanthomatous Ameloblastoma (CAA) and Canine Oral Squamous Cell Carcinoma (COSCC). The study identified a rare cell type in CAA that expresses the ERBB4 gene, suggesting that the FDA-approved drug neratinib could be an effective treatment for reducing tumor growth.

What happened

Existing drug could treat invasive canine oral tumors Gaby Clark Scientific Editor Robert Egan Senior Editor A benign but invasive canine oral cancer is often mistaken for a similar malignant one, leading to misdiagnoses in close to a third of cases.

Why it matters

But a new diagnostic tool can now distinguish between the two, according to a new study that also identified a promising FDA-approved drug ready for clinical trials.

Common ground

Canine acanthomatous ameloblastoma (CAA) is a benign but locally aggressive, destructive and invasive tumor that is relatively common in dogs.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
