Head and neck cancers account for an estimated 549,000 global cancer diagnoses each year. While tobacco use, alcohol consumption, and HPV16 infection are considered to be the major risk factors for this disease, occupational risk factors, including exposure to asbestos, have also been described, although dust exposures other than asbestos have been historically understudied. We have investigate...

Immunotherapy has become one of the most promising approaches in tumor therapy, and there are numerous associated clinical trials China. As an immunosuppressive tumor, head neck squamous cell carcinoma (HNSCC) carries a high mutation burden, making immune checkpoint inhibitors candidates this field due to their unique mechanism action. The present review outlines comprehensive multidisciplinary...

Here we showed that exogenous miR-372 expression and knockdown of p62 (sequestosome1 or SQSTM1), both increased migration of head and neck squamous cell carcinoma (HNSCC) cells. p62 induced phase II detoxification enzyme NADPH quinone oxidoreductase 1 (NQO1), which decreased ROS levels and cell migration. Also, miR-372 decreased p62 during hypoxia, thus increasing cell migration. Levels of miR-...

Head and neck squamous cell carcinoma (HNSCC) is a highly lethal cancer. Previously, we identify head and neck cancer initiating cells (HN-CICs), which are highly tumorigenic and resistant to conventional therapy. Therefore, development of drug candidates that effectively target HN-CICs would benefit future head and neck cancer therapy. In this study, we first successfully screened for an activ...

Smad4 is a central mediator of TGF-beta signaling, and its expression is downregulated or lost at the malignant stage in several cancer types. In this study, we found that Smad4 was frequently downregulated not only in human head and neck squamous cell carcinoma (HNSCC) malignant lesions, but also in grossly normal adjacent buccal mucosa. To gain insight into the importance of this observation,...

Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer, and its prognosis remains poor. The poor prognosis results from recurrence, metastasis, and therapeutic resistance. Recently, cancer stem cells (CSCs) were shown to result in treatment failure, but their function and identification are not well understood in HNSCC. Previously, several markers of CSCs in HNSCC have be...

Head and neck squamous cell carcinoma (HNSCC), a heterogeneous group of upper aerodigestive tract malignancies, is the seventh most common cancer worldwide. Tobacco use and alcohol consumption were the most identified risk factors of HNSCC. However, human papilloma virus, a sexually transmitted infection, has been determined as another primary cause of HNSCC. Early-stage disease is treated with...

Introduction: The goal of this study was to analyze the causes of death in patients with loco-regionally advanced squamous cell carcinoma (HNSCC) of the head and neck treated with multimodality treatment. Materiel: The mortality records of 138 advanced head and neck patients treated in our department with surgery and adjuvant (chemo) radiotherapy from 2007 to 2013 were collected and reviewed in...

BACKGROUND Head and neck squamous cell carcinoma (HNSCC) is the sixth most common malignancy in the world in developed countries. Despite the intense research in the area of squamous cell carcinomas of head and neck (HNSCC), long-term survival rate has not changed significantly in this malignancy during recent decades. METHODS In this study, we focused on TP53 mutations in specific regions, i...

In this study, endogenous long chain ceramides were measured in 32 human head and neck squamous cell carcinoma (HNSCC) and 10 nonsquamous head and neck carcinoma tumor tissues, as compared with adjacent noncancerous tissues, by liquid chromatography/mass spectroscopy. Interestingly, only one specific ceramide, C(18:0)-ceramide, was selectively down-regulated in the majority of HNSCC tumor tissu...
