Core Tip
Core tip: The cancer stem cells (CSCs) theory offers an insight into why currently available therapies for head and neck cancer fail so often. Eradication of cancers may require the targeting and elimination of CSCs, especially for head and neck squamous cell cancer (HNSCC). This represents a challenge because many pathways, such as those involved in self-renewal, are shared by CSCs and their normal counterparts and might lead to major toxicities. Developing radio sensitizing strategies is investigated and appears to eliminate CSCs. Overcoming chemo resistance, radio resistance and immune evasion mechanisms of CSCs remains a cornerstone of novel adjuvant therapies specifically targeting CSCs in HNSCC.
