BACKGROUND: The 8th edition American Joint Committee on Cancer (AJCC8) provides the same nodal staging system for mucosal and cutaneous squamous cell carcinoma of the head and neck (HNcSCC) and includes extranodal extension (ENE) as an adverse prognostic criterion. This study evaluates the prognostic efficacy of the AJCC8 pathologic nodal staging system (pN) for HNcSCC. METHODS: Univariate analysis of 382 patients with metastatic HNcSCC staged according to both the 7th (AJCC7) and the 8th edition staging systems...

Importance: The management of lentigo maligna (LM) and LM melanoma (LMM) is challenging because of extensive subclinical spread and its occurrence on cosmetically sensitive areas. Reflectance confocal microscopy (RCM) improves diagnostic accuracy for LM and LMM and can be used to delineate their margins. Objectives: To evaluate whether handheld RCM with radial video mosaicing (HRCM-RV) offers accurate presurgical assessment of LM and LMM margins. Design, Setting, and Participants: This prospective study included consecutive patients with biopsy-proven LM and LMM located on the head and neck area who sought consultation for surgical management from March 1, 2016, through March 31, 2017, at the Dermatology Service of the Memorial Sloan Kettering Cancer Center...

A closer association has been found between the microRNA-146a rs2910164 polymorphism and the risk of head and neck carcinoma in some molecular epidemiological studies. Recently two meta-analyses were performed to explore the relationship between miRNA-146a polymorphisms and the susceptibility of squamous cell carcinoma of the head and neck (SCCHN); however, they yielded conflicting results in susceptibility regarding ethnic variations. Hence, the present study was performed to explain the relationship between the miRNA-146a rs2910164 polymorphism and the risk of SCCHN development of Chinese patients...

In radiation treatment planning, the esophagus is an important organ-at-risk that should be spared in patients with head and neck cancer or thoracic cancer who undergo intensity-modulated radiation therapy. However, automatic segmentation of the esophagus from CT scans is extremely challenging because of the structure's inconsistent intensity, low contrast against the surrounding tissues, complex and variable shape and location, and random air bubbles. The goal of this study is to develop an online atlas selection approach to choose a subset of optimal atlases for multi-atlas segmentation to delineate esophagus automatically...

FP treatment, which combines 5-fluorouracil (5-FU) and cisplatin (CDDP) chemotherapy, is widely used for treatment of advanced head and neck cancer (HNC). It has been suggested that these drugs cause immunomodulation in the cancer microenvironment, for example, downregulation of immunosuppressive cells such as regulatory T-cells (Tregs) and myeloid-derived suppressive cells (MDSCs), activating dendritic cells (DCs), and upregulation of tumor antigens and major histocompatibility complex (MHC) molecules in cancer cells leads to enhancement of cancer immunity, which is important in cancer treatment, as well as providing a direct killing effect...

Immune evasion is a hallmark feature of cancer, and it plays an important role in tumour initiation and progression. In addition, tumour immune evasion severely hampers the desired antitumour effect in multiple cancers. In this study, we aimed to investigate the role of the Notch pathway in immune evasion in the head and neck squamous cell carcinoma (HNSCC) microenvironment. We first demonstrated that Notch1 signalling was activated in a Tgfbr1/Pten-knockout HNSCC mouse model. Notch signalling inhibition using a γ-secretase inhibitor (GSI-IX, DAPT) decreased tumour burden in the mouse model after prophylactic treatment...

The fluoropyrimidine anticancer drugs, especially 5-fluorouracil (5-FU) and capecitabine, are frequently prescribed for several types of cancer, including breast, colorectal, head and neck and gastric cancer. In the current drug labels of 5-FU and capecitabine in the European Union and the United States of America no adaptive dosing strategies are incorporated for polymorphic metabolism of 5-FU.Although treatment with fluoropyrimidines is generally well tolerated, a major clinical limitation is that a proportion of the treated population experiences severe, sometimes life-threatening, fluoropyrimidine-related toxicity...

OBJECTIVES/HYPOTHESIS: We previously reported that high-volume hospital head and neck cancer (HNCA) surgical care is associated with decreased mortality, largely explained by reduced rates of failure to rescue. Frailty is an independent predictor of mortality, but is significantly less likely in patients receiving high-volume care. We investigate whether differences in frailty rates explain the relationship between volume and outcomes in HNCA patients and whether frailty confounds the relationship between failure to rescue and mortality...

BACKGROUND: Mucosal melanomas in the head and neck region are most often located in the nasal cavity and paranasal sinuses. To the authors' knowledge, the prognostic effects of lymph node metastasis in patients with sinonasal mucosal melanoma (SNMM) have not been established. Therefore, the objective of the current study was to determine the effects of lymph node metastasis on survival. METHODS: The current study included 198 patients with SNMM who had been treated between 1985 and 2016 at The University of Texas MD Anderson Cancer Center in Houston...

OBJECTIVE: Marfan syndrome (MFS) involves a deficiency of the structural extracellular matrix component fibrillin-1 and overactivation of the transforming growth factor-β (TGF-β) signalling pathway. The TGF-β signalling pathway also actively participates in malignant transformation. Although anecdotal case reports have suggested associations between MFS/MFS-like conditions and several haematological and solid malignancies, such associations have not been thoroughly evaluated in large-scale studies...

Fanconi anemia (FA) is a rare genetic disorder associated with predisposition to head and neck and gynecological squamous cell cancers. In the general population, these cancers are commonly linked to human papillomavirus (HPV) infection. Antibodies to natural HPV infection and HPV vaccination were evaluated in 63 individuals with FA while considering host immune factors. Approximately 30% of reportedly unvaccinated participants were seropositive (HPV6-38%, HPV11-25%, HPV16-26%, and HPV18-26%). Seropositivity was significantly associated with having had sex regardless of age (p=...

Oral squamous cell carcinoma (OSCC) is the most prevalent pathological cancer occurring in the head and neck area. Progress has previously been made regarding treatment strategies of OSCC, however the 5‑year survival rate of these patients is only 50%. The present study examined if leflunomide (LEF), a drug primarily used for the treatment of rheumatoid arthritis, exhibited antitumor effects in OSCC. The results demonstrated that LEF inhibited cell proliferation and blocked the cell cycle at the S phase in OSCC cells, with upregulation of cyclin A protein expression...
