In conclusion, this study highlights the radio-sensitizing anticancer efficacy of Ova in human metastatic NPC cells, as well as its putative cytoprotective role in normal bronchial cells, for airway surface liquid maintenance and homeostasis during or after radiotherapy.

Conclusions: 3D-HDR-BT achieves favorable clinical outcomes with mild late toxicity in patients with locally rNPC. Introduction Nasopharyngeal carcinoma (NPC), a tumor of epithelial origin, is a malignant disease of the head and neck common in southern China, especially in Guangdong province (1). As a result of advances in modern imaging and irradiation techniques, the 5-year overall survival (OS) of patients with newly diagnosed NPC without metastasis has reached 75% after external beam radiotherapy (EBRT) in Asia (2, 3). However, local recurrence, which occurs in 18–40% of patients, remains a major reason for...

CONCLUSIONS: The selection of lymph node target volumes for head and neck cancers treated with IMRT/VMAT or other highly conformal techniques (e.g. proton therapy) requires a rigorous approach. This updated proposal of selection should help clinicians for the selection of lymph nodes target volumes and contribute to increase consistency. PMID: 31005201 [PubMed - in process]

Conclusions In the span of a very short time—less than a decade—robotic head and neck surgery has transformed the management of the head and neck cancer, and it seems clear that the future of treatment for these cancers lies in a multimodal approach in which TORS is likely to play an important role. Nevertheless, it is important to keep in mind that the current indications for TORS are limited and long-term data on the safety and oncological outcomes are needed to better understand the true role of TORS in treatment of head and neck cancer. Nonetheless, the emergence of ever more advanced robotic instruments i...

In this study, we aim to investigate the role of circRNAs in the radioresistant NPC. Human circRNA array was performed in radioresistant and radiosensitive NPC samples to screen the differentially expressed circRNAs. We found that circRNA_000543 expression was upregulated in NPC tissues compared adjacent tissues, and was higher in radioresistant samples than in radiosensitive NPC samples. NPC patients with high circRNA_000543 expression displayed poorer overall survival compared with the patients with low circRNA_000543. Further investigations demonstrated that circRNA_000543 knockdown sensitized NPC cells by targeting miR...

Radiation therapy (RT) is a mainstay in the management of nasopharyngeal carcinoma (NPC), commonly in combination with chemotherapy [1]. Given that the RT target volume for these patients is at the base of the skull (and often intracranial), intimate with numerous critical central nervous system (CNS) structures, clinicians must balance goals of maximizing disease control while minimizing treatment-related toxicity [2]. The use of intensity-modulated RT (IMRT) in the treatment of NPC has allowed for enhanced delivery of therapeutic doses and improved quality of life (QOL) [3 –5].
