Efficacy of beta-hydroxy-beta-methylbutyrate, arginine, and glutamine for the prevention of mucositis induced by platinum-based chemoradiation in head and neck cancer: A phase II study.

Background & Aims: The current standard treatment modality for advanced head and neck squamous cell carcinoma (HNSCC), namely platinum-based (PB) concurrent chemoradiotherapy (CRT), is associated with frequent severe mucositis which is responsible for the multiple acute and late adverse events. So far, effective preventive methods for this CRT-induced mucositis are not identified. In the current study, we examined the prophylactic effects of beta-hydroxy-beta-methylbutyrate (HMB), arginine (Arg), and glutamine (Gln) (HMB/Arg/Gln) mixture.

Is chemoimmunotherapy a game changer in the treatment of locally advanced head and neck squamous cell carcinoma?

Pembrolizumab and chemotherapy (chemoimmunotherapy) were administered to 2 head and neck squamous cell carcinoma (HNSCC) patients with extremely advanced local tumors and distant metastases with palliative intent. However, they demonstrated strikingly good responses and achieved remission. Expanded application of induction chemoimmunotherapy may be useful for locally advanced HNSCC.
