The Eph/ephrin signaling has an ambiguous role in squamous cell carcinomas of the oral region, playing both a suppressive and oncogenic role. In salivary gland cancers, the results are reserved, although they suggest that some molecules are associated with a worse prognosis for patients. This review offers a comprehensive summary of the existing literature, underscoring the evidence that supports the involvement of the Eph/ephrin signaling in oral and maxillofacial cancers. Additionally, we examine molecular discoveries that may present promising therapeutic targets for these malignancies.
