Head and Neck Squamous Cell Carcinomas (HNSCC) are characterized by a large heterogeneity in terms of the location and risk factors. For a few years now, immunotherapy seems to be a promising approach in the treatment of these cancers, but a better understanding of the immune context could allow to offer a personalized treatment and thus probably increase the survival of HNSCC patients. In this context, we evaluated the infiltration of FoxP3+ Tregs on 205 human formalin-fixed paraffin-embedded HNSCC and we assessed its prognostic value compared to other potential prognostic factors, including HPV infection...

BACKGROUND: To report our institutional experience with intraoperative radiotherapy for persistent or recurrent head and neck cancer. METHODS: Sixty-one patients were treated with salvage surgery and intraoperative radiation therapy (IORT). Fifty-eight patients (95%) had previously received external beam radiotherapy (EBRT) as a component of their definitive therapy. Forty-four patients (72%) had squamous cell carcinoma (SCC). Surgical margins were positive in 28 patients (46%)...

BACKGROUND: Organ preservation protocols have increasingly been applied for the treatment of head and neck cancers, including hypopharyngeal squamous cell carcinoma (HSCC). We sought to evaluate whether patients treated with primary surgery followed by adjuvant therapy had survival benefit over patients treated with initial nonsurgical modalities. METHODS: We retrospectively reviewed patients with new diagnosis of HSCC at the University of Pittsburgh (1994-2014) treated with either primary total laryngectomy with pharyngectomy or organ preservation...

BACKGROUND: Lung cancer 5-year survival has doubled over 15 years. Although the risk of second primary cancer is recognised, quantification over time is lacking. We describe the incidence of second and higher order smoking-related primary cancers in lung cancer survivors, identifying high-incidence groups and how incidence changes over time from first diagnosis. METHODS: Data on smoking-related primary cancers (lung, laryngeal, head and neck, oesophageal squamous cell carcinoma and bladder) diagnosed in England between 2000 and 2014 were obtained from Public Health England National Cancer Registration and Analysis Service...

BACKGROUND AND OBJECTIVES: Although there is scientific evidence demonstrating causation of human papilloma virus (HPV) on squamous cell carcinoma of head and neck, its percentage of causality on the anatomic region remains in dispute. This study was developed with the objectives of evaluating the relationship between HPV and oral and oropharyngeal squamous cell carcinomas (OOSCC), and of studying the correlation between HPV detection tests (PCR and p16). MATERIAL AND METHOD: Retrospective study of patients treated for OOSCC during 2011, with a follow-up of 6 years...

BACKGROUND: A promising arsenal of histone deacetylase (HDAC)-targeted treatment has emerged in the past decade, as the abnormal targeting or retention of HDACs to DNA regulatory regions often occurs in many cancers. Head and neck squamous cell carcinoma (HNSCC) is one of the most aggressive malignancies worldwide associated with poor overall survival in late-stage patients. HDAC inhibitors have great potential to treat this devastating disease; however, few has been studied regarding the beneficial role of HDAC inhibition in anti-HNSCC therapy and the underlying molecular mechanisms remain elusive...

Background: Sequencing studies across multiple cancers continue to reveal mutations and genes involved in the pathobiology of these cancers. Exome sequencing of oral cancers, a subset of Head and Neck Squamous cell Carcinomas (HNSCs) common among tobacco-chewing populations, revealed that ∼34% of the affected patients harbor mutations in the CASP8 gene . Uterine Corpus Endometrial Carcinoma (UCEC) is another cancer where ∼10% cases harbor CASP8 mutations. Caspase-8, the protease encoded by CASP8 gene, plays a dual role in programmed cell death, which in turn has an important role in tumor cell death and drug resistance...

Despite an overall decline in the incidence of tobacco-related cancers, human papillomavirus (HPV)-related head and neck squamous cell carcinoma (HNSCC) of the oropharynx is on the rise. The prognosis of HPV-related oropharynx cancer (HPV-OPC) is generally favorable even in locoregionally advanced disease, and a variety of treatment options are available. Though the primary treatment modality of choice remains definitive radiation (RT), surgical resection followed by appropriate adjuvant therapy remains an option, especially in those patients who may not be favorable candidates for definitive radiotherapy, particularly when concurrent chemotherapy is warranted...

PURPOSE: Head and neck squamous cell carcinoma (HNSCC) is driven largely by the loss of tumor suppressor genes, including NOTCH1, but lacks a biomarker-driven targeted therapy. Although the PI3K/mTOR pathway is frequently altered in HNSCC, the disease has modest clinical response rates to PI3K/mTOR inhibitors and lacks validated biomarkers of response. We tested the hypothesis that an unbiased pharmacogenomics approach to PI3K/mTOR pathway inhibitors would identify novel, clinically relevant molecular vulnerabilities in HNSCC with loss of tumor suppressor function...

Metastasis is one of the primary causes for high mortality in patients with squamous cell carcinoma of the head and neck (SCCHN). Our previous study showed that chemokine (C-C motif) ligand 18 (CCL18), derived from tumour-associated macrophages (TAMs), regulates SCCHN metastasis by promoting epithelial-mesenchymal transition (EMT) and preserving stemness. However, the underlying mechanism needs to be further investigation. Interestingly, metadherin (MTDH) expression was induced when SCCHN cells were stimulated with recombinant CCL18 protein in this study...

Introduction: Patients with bulky metastases of squamous cell carcinoma of the head and neck represent a challenge for the therapeutic decision; balance between oncological control and complications should be achieved. The therapeutic sequence has no impact on survival but sequelae. Objective: We analyze the oncological results in patients with bulky metastases on the neck treated with induction chemotherapy and with up-front neck dissection. Method: Retrospective analysis of patients undergoing treatment for cervical lymph node metastasis of squamous cell carcinoma; The therapeutic sequence was decided based on volume, resectability, site, and size of the primary and general condition of the patient...

Context: Nimotuzumab is the only anti-epidermal growth factor receptor monoclonal antibody which can be safely added to concurrent chemoradiotherapy (CRT) to improve efficacy in the management of unresectable, locally advanced squamous cell carcinoma of head and neck (LA-SCCHN). However, the evidence available on this is limited. Aims: We retrospectively investigated efficacy and safety of nimotuzumab when combined with chemoradiation for LA-SCCHN. Settings and Design: Hospital records of 39 patients from January 2012 to December 2016 diagnosed with locally advanced (Stage III-IVb), unresectable SCCHN, and treated with concurrent CRT with weekly nimotuzumab were reviewed retrospectively after fulfilling the inclusion/exclusion criteria...

Head and neck cancer (HNC) is the sixth cause of cancer-related death worldwide. Head and neck squamous cells carcinoma (HNSCC) is the most frequent subtype of HNC. The development of HNSCC is associated to alcohol consumption, smoking or infection by high-risk human Papillomavirus (HR-HPV). Although the incidence of cancers associated with alcohol and tobacco has diminished, HNSCC associated with HR-HPV has significantly increased in recent years. However, HPV-positive HNSCC responds well to treatment, which includes surgery followed by radiation or chemoradiation therapy...

As a member of the Sirtuins family in mammals, SIRT7 locates in nucleus and is a highly specific H3K18Ac (acetylated lysine 18 of histone H3) deacetylase. Recent studies showed that SIRT7 could participate in the ribosomal RNA transcription, cell metabolism, cell stress and DNA damage repair through various signaling pathways. In addition, SIRT7 is also closely related with aging, heart disease and fatty liver. In particular, SIRT7 plays important roles in the regulation of initiation and development of various tumors, such as liver cancer, gastric cancer, breast cancer, bladder cancer, colorectal cancer, and head/neck squamous cell carcinoma...

PURPOSE: Treatment guidelines have not been established for unknown primary head and neck squamous cell carcinoma (SCC). For these patients, chemoradiotherapy (CRT) can provide a better prognosis than that for patients with other head and neck cancers. The presence of HPV in the tumor is associated with a better outcome. However, not all patients with HPV-positive unknown primary head and neck SCC experience good treatment outcomes in actual clinical settings. METHODS: We thus retrospectively determined the Ki-67 proliferation index and p16 expression status to assess the associations of these parameters with treatment outcomes of patients with unknown primary head and neck SCC...
