Abstract
Persistent high-risk human papillomavirus (HR-HPV) infections cause cervical cancer and a fraction of head and neck cancer. To investigate whether HR-HPV infection might be also involved in the development of gastric cancer (GC), we developed a platform utilizing a rolling circle amplification (RCA)-based nested L1 polymerase chain reaction with Sanger sequencing to genotype the HPV DNA in cancer tissues of 361 GC and 89 oropharyngeal squamous cell carcinomas (OPSCC). HPV transcriptional activity was determined by E6/E7 mRNA expression and a 3' rapid amplification of cDNA ends was performed to identify HPV integration and expression of virus-host fusion transcripts. Ten of 361 GC, 2 of 89 OPSCC, and 1 of 22 normal adjacent tissues were HPV L1 DNA-positive. Five of the 10 HPV-positive GC were genotyped as HPV16 by sequencing and 1 of 2 GC with RCA/nested HPV16 E6/E7 DNA detection exhibited HPV16 E6/E7 mRNA. Two OPSCC displayed HPV16 L1 DNA and E6/E7 mRNA, of which 1 OPSCC tissue showed virus-host RNA fusion transcripts from an intron region of KIAA0825 gene. Together, our data reveal viral oncogene expression and/or integration in GC and OPSCC and a possible etiology role of HPV infections in gastric carcinogenesis.

Abstract
The incidence of high-risk Human Papillomavirus (HR-HPV)-driven head and neck squamous cell carcinoma (HNSCC) is on the rise globally. HR-HPV-driven HNSCC displays molecular and clinical characteristics distinct from HPV-uninvolved cases. Therapeutic strategies for HR-HPV-driven HNSCC are under investigation. HR-HPVs encode the oncogenes E6 and E7, which are essential in tumorigenesis. Meanwhile, involvement of E6 and E7 provides attractive targets for developing new therapeutic regimen. Here we will review some of the recent advancements observed in preclinical studies and clinical trials on HR-HPV-driven HNSCC, focusing on nanotechnology related methods. Materials science innovation leads to great improvement for cancer therapeutics including HNSCC. This article discusses HPV-E6 or -E7- based vaccines, based on plasmid, messenger RNA or peptide, at their current stage of development and testing as well as how nanoparticles can be designed to target and access cancer cells and activate certain immunology pathways besides serving as a delivery vehicle. Nanotechnology was also used for chemotherapy and photothermal treatment. Short interference RNA targeting E6/E7 showed some potential in animal models. Gene editing by CRISPR-CAS9 combined with other treatments has also been assessed. These advancements have the potential to improve the outcome in HR-HPV-driven HNSCC, however breakthroughs are still to be awaited with nanomedicine playing an important role.

Abstract
Human papillomavirus (HPV) infection identified as a definitive human carcinogen is increasingly being recognized for its role in carcinogenesis of human cancers. Up to 38%-80% of head and neck squamous cell carcinoma (HNSCC) in oropharyngeal location (OPSCC) and nearly all cervical cancers contain the HPV genome which is implicated in causing cancer through its oncoproteins E6 and E7. Given by the biologically distinct HPV-related OPSCC and a more favorable prognosis compared to HPV-negative tumors, clinical trials on de-escalation treatment strategies for these patients have been studied. It is therefore raised the questions for the patient stratification if treatment de-escalation is feasible. Moreover, understanding the crosstalk of HPV-mediated malignancy and immunity with clinical insights from the proportional response rate to immune checkpoint blockade treatments in patients with HNSCC is of importance to substantially improve the treatment efficacy. This review discusses the biology of HPV-related HNSCC as well as successful clinically findings with promising candidates in the pipeline for future directions. With the advent of various sequencing technologies, further biomolecules associated with HPV-related HNSCC progression are currently being identified to be used as potential biomarkers or targets for clinical decisions throughout the continuum of cancer care.

Abstract
Immunotherapies such as immune checkpoint blockade benefit only a portion of patients with head and neck squamous cell carcinoma. The multidisciplinary field of nanomedicine is emerging as a promising strategy to achieve maximal anti-tumor effect in cancer immunotherapy and to turn non-responders into responders. Various methods have been developed to deliver therapeutic agents that can overcome bio-barriers, improve therapeutic delivery into the tumor and lymphoid tissues and reduce adverse effects in normal tissues. Additional modification strategies also have been employed to improve targeting and boost cytotoxic T cell-based immune responses. Here, we review the state-of-the-art use of nanotechnologies in the laboratory, in advanced preclinical phases as well as those running through clinical trials assessing their advantages and challenges.

Abstract
Cancer stem cell (CSC)-related therapy resistance has become a new obstacle to the successful application of cancer treatment and head and neck squamous cell carcinoma (HNSCC) is no exception to this finding. Head and neck squamous cell carcinoma is highly immune-suppressive, and recently the immune suppression and invasion of HNSCC-CSCs have been characterized. These characteristics have received research and clinical attention because they would enable the stratification of patients into specific cancer subtypes and, consequently, the establishment of new therapeutic approaches with improved efficacy. This review discusses the feasibility of CSC-targeted strategies and their incorporation with nanotechnology to improve the efficacy of cancer immunotherapy.

Abstract
BACKGROUND Disulfiram (DSF) is a drug used for treatment of alcoholism that has also displayed promising anti-cancer activity. It unfolds its effects by inhibiting the enzyme activity of aldehyde dehydrogenase (ALDH) isoforms. METHODS MTT assay, spheroid formation, clonogenicity assay, qRT-PCR, and ALDH enzyme activity analysis were performed using ovarian cancer cell lines IGROV1, SKOV3 and SKOV3IP1. Cell cycle analyses and measurement of intracellular reactive oxygen species (ROS) were carried out by flow cytometry. ALDH+ and ALDH- cells were isolated by FACS sorting. RESULTS ALDH activity was inhibited in ovarian cancer stem cells (the proportion of ALDH+ cells was reduced from 21.7% to 0.391%, 8.4% to 0%, 6.88% to 0.05% in cell lines IGROV1, SKOV3, and SKOV3IP1, respectively). DSF with or without the cofactor copper (Cu2+) exhibited cytotoxicity dose- and time-dependent and enhanced cisplatin-induced apoptosis. DSF + Cu2+ increased intracellular ROS levels triggering apoptosis of ovarian cancer stem cells (CSC). Significantly more colony and spheroid formation was observed in ALDH+ compared with ALDH- cells (P < 0.01). Moreover, ALDH+ cells were more resistant to cisplatin treatment compared with ALDH-cells (P < 0.05) and also exhibited a lower basal level of ROS. However, no significant difference in ROS accumulation nor in cellular viability was observed in ALDH + cells in comparison to ALDH- cells after pre-treatment with DSF (0.08 μM). CONCLUSION Our findings provide evidence that DSF might be employed as a novel adjuvant chemotherapeutic agent in combination with cisplatin for treatment of ovarian cancer.

Abstract
Although patients having head and neck squamous cell carcinoma (HNSCC) have high mortality, standardized prognostic tools are unavailable. As such, having a validated simple prognostic scoring system to help predict mortality in these high-risk patients is urgently needed. The current study aimed to develop and internally validate a prognostic scoring system for overall mortality in human papillomavirus (HPV)-independent HNSCC patients. Data on 400 consecutive patients from the Cancer Genome Atlas database with a known HPV-RNA negative status were analyzed. A prognostic model to predict patient overall mortality was developed using the logistic regression beta coefficients and a simple risk score was created. The model was internally validated using bootstrap validation with 2000 replications. Five covariates (age, pT, pN, perineural invasion, and EAp53 score) were used in the development of the mortality risk score in the final model. Three risk groups were stratified based on the prognostic scores: low-risk (<96 points), medium-risk (96-121 points), and high-risk (≥122 points) with a survival of 76%, 62% and 35%, respectively. The proposed model presented good discrimination in both the development (AUC = 0.76; 95% CI 0.70, 0.81) and bootstrap validation (AUC = 0.76; 95% CI 0.70, 0.81) with a non-significant Hosmer-Lemeshow chi-square of 6.17 (p = 0.63). The proposed prognostic scoring system is easy to use to predict patient overall mortality and could also help in the appropriate allocation of medical resources while managing HNSCC patients. External validation (including re-calibration if needed) should be conducted to test the model's generalizability in different populations.

Abstract
Current systemic cancer treatment in head and neck squamous cell carcinoma (HNSCC) is moving toward more personalized approaches such as de-escalation protocols human-papilloma-virus dependent HNSCC or application of checkpoint inhibitors. However, these treatments have been challenged by cancer stem cells (CSC), a small population within the bulk tumor, which are leading to treatment failure, tumor recurrence, or metastases. This review will give an overview of the characteristics of HNSCC-CSC. Specifically, the mechanisms by which HNSCC-CSC induce tumor initiation, progression, recurrence, or metastasis will be discussed. Although evidence-based treatment options targeting HNSCC-CSC specifically are still being sought for, they warrant a promise for additional and sustainable treatment options where for HNSCC patients where others have failed.

Abstract
In recent decades, tools of molecular biology have enabled researchers to genetically modify model organisms, including human cells. RNAi, zinc-finger nucleases, transcription activator-like effector nucleases, CRISPR-Cas9 (clustered regularly-interspaced short palindromic repeats and CRISPR-associated protein 9), retro- or lentiviral gene transfer, and many other methods can be utilized to remove genes, add genes, or change their expression. Within the same timeframe, survival rates for many highly malignant tumor diseases have not improved substantially. If modern medicine could apply even a subset of research methods in clinical management, which are already well established and controllable in basic research laboratories, this could strongly impact patients' prognosis. CRISPR-Cas9 is a method to precisely target and manipulate genomic loci and recent studies have attempted to use this method as a genetic treatment for Duchenne muscular dystrophy, blood disorders, autosomal-dominant hearing loss, and cancer. Some of these approaches target mutant genomic sequences specifically and try to avoid affecting the respective normal loci. Considering obvious genetic risks opposing the objected benefits, data are needed to show whether CRISPR technology is suitable as a future cancer therapy approach or not. Here, we develop strategies for the specific targeting of viral cancer drivers and oncogenes activated by mutation, using the latest CRISPR technology. Cancer Res; 78(19); 5506-12. ©2018 AACR.

Abstract
CD8+ cytotoxic T-cell (CTL) specific for non-mutated, wild type (wt) sequence p53 peptides derived from wt or mutant p53 molecules expressed in head and neck squamous cell carcinomas (HNSCC) have been detected in the circulation of patients with this disease. The frequency and differentiation/maturation phenotypes of these anti-tumor specific CTL can reflect the host’s immunologic response. Therefore, we investigated the frequency and phenotypes of wt sequence p53 peptide-specific CTL in patients with HNSCC (n = 33) by flow cytometric analysis using HLA-A*0201 tetrameric peptides (tet) complexed with the wt sequence p53264–272 or p53149–157 peptide and co-staining with phenotypic markers. One main finding was that increasing frequencies of tet+ CD8+ T cells in patients’ circulation correlated with increased frequencies of inactive naïve tet+ cells, while those with effector memory and terminally differentiated phenotypes, which are associated with positive anti-tumor immune responses, decreased. We also found that the frequency of circulating tet+ CD8+ T cells negatively correlated with p53 expression in tumor tissues and tumor stage. Our findings support further clinical-based investigations to define the frequencies and phenotypes of wt sequence p53 peptide-specific CD8+ T cells to predict disease severity, enhance selection of patients for inclusion in vaccination trials and highlight prerequisites to enhance immune susceptibility by activation of inactive naïve tet+ T cells and/or enhancing circulating effector T cell activity by checkpoint blockage.

Abstract
One of the greatest challenges in systemic treatment of head and neck squamous cell carcinoma (HNSCC) is a small tumor cell population, namely, cancer stem-like cells (CSC). CSC can regenerate and maintain a heterogenic tumor by their self-renewal capacity. Their potential ability to be more resistant to and survival after chemo- and radiation therapy was also identified. Further studies have shown that reactive oxygen species (ROS) contribute to this CSC-associated resistance. In this review, we focus on the current knowledge of HNSCC-CSC, with regard to ROS as a possible and novel therapeutic approach in targeting CSC.

Abstract
Many environmental, host, and microbial characteristics have been recognized as risk factors for dissemination of extrapulmonary tuberculosis (EPTB). However, there are few population-based studies investigating the association between the primary sites of tuberculosis (TB) infection and mortality during TB treatment. De-identified population-based surveillance data of confirmed TB patients reported from 2009 to 2015 in Texas, USA, were analyzed. Regression analyses were used to determine the risk factors for EPTB, as well as its subsite distribution and mortality. We analyzed 7007 patients with exclusively pulmonary TB, 1259 patients with exclusively EPTB, and 894 EPTB patients with reported concomitant pulmonary involvement. Age ≥45 years, female gender, human immunodeficiency virus (HIV)-positive status, and end-stage renal disease (ESRD) were associated with EPTB. ESRD was associated with the most clinical presentations of EPTB other than meningeal and genitourinary TB. Patients age ≥45 years had a disproportionately high rate of bone TB, while foreign-born patients had increased pleural TB and HIV+ patients had increased meningeal TB. Age ≥45 years, HIV+ status, excessive alcohol use within the past 12 months, ESRD, and abnormal chest radiographs were independent risk factors for EPTB mortality during TB treatment. The epidemiologic risk factors identified by multivariate analyses provide new information that may be useful to health professionals in managing patients with EPTB.

Abstract
Consistent discrepancies in the p16/HPV-positivity have been observed in head and neck squamous cell carcinoma (HNSCC). It is therefore questionable, if all HPV+ and/or p16+ tested cancers are HPV-driven. Patients down-staged according to the HPV-dependant TNM are at risk for undertreatment and data in clinical trials may be skewed due to false patient inclusion. We performed a meta-analysis to classify clinical outcomes of the distinct subgroups with combined p16 and HPV detection. 25 out of 1677 publications fulfilled the inclusion criteria. The proportion of the subgroups was 35.6% for HPV+/p16+, 50.4% for HPV-/p16-, 6.7% for HPV-/p16+ and 7.3% for HPV+/P16-. The HPV+/p16+ subgroup had a significantly improved 5-year overall-survival (OS) and disease-free-survival in comparison to others both for HNSCC and oropharyngeal cancers. The 5-year OS of the HPV-/p16+ HNSCC was intermediate while HPV+/p16- and HPV-/p16- had the shortest survival outcomes. The clearly distinct survival of HPV-/p16+ cancers may characterize a new relevant HPV-independent subtype yet to be biologically characterized. The possibility also exists that in some HPV+/p16+ cancers HPV is an innocent bystander and p16 is independently positive. Therefore, in perspective, HPV-testing should distinguish between bystander HPV and truly HPV-driven cancers to avoid potential undertreatment in HPV+ but non-HPV-driven HNSCC.

Abstract
Cetuximab is the single targeted therapy approved for the treatment of head and neck cancer (HNSCC). Predictive biomarkers have not been established and patient stratification based on molecular tumor profiles has not been possible. Since EGFR pathway activation is pronounced in basal subtype, we hypothesized this activation could be a predictive signature for an EGFR directed treatment. From our patient-derived xenograft platform of HNSCC, 28 models were subjected to Affymetrix gene expression studies on HG U133+ 2.0. Based on the expression of 821 genes, the subtype of each of the 28 models was determined by integrating gene expression profiles through centroid-clustering with previously published gene expression data by Keck et al. The models were treated in groups of 5-6 animals with docetaxel, cetuximab, everolimus, cis- or carboplatin and 5-fluorouracil. Response was evaluated by comparing tumor volume at treatment initiation and after 3 weeks of treatment (RTV). Tumors distributed over the 3 signature-defined subtypes: 5 mesenchymal/inflamed phenotype (MS), 15 basal type (BA), 8 classical type (CL). Cluster analysis revealed a strong correlation between response to cetuximab and the basal subtype. RTV MS 3.32 vs. BA 0.78 (MS vs. BA, unpaired t-test, p 0.0002). Cetuximab responders were distributed as following: 1/5 in MS, 5/8 in CL and 13/15 in the BA group. Activity of classical chemotherapies did not differ between the subtypes. In conclusion basal subtype was associated with response to EGFR directed therapy in head and neck squamous cell cancer patient-derived xenografts.

Abstract
The aim of the present study was to evaluate the clinical effectiveness and toxicity of docetaxel with 5-fluorouracil and cisplatin as combination treatment in patients with curable or metastatic/recurrent head and neck cancer by a retrospective cohort study of patients treated at a single institution between 2007 and 2012. Patients with locally advanced, metastatic and/or recurrent squamous cell carcinoma of the head and neck (SCCHN), who were treated with a combination therapy including docetaxel, were considered as eligible. Survival data, clinical side effects, quality of life (QoL) and toxicity profile were retrieved from patient charts, analyzed and scored according to the National Cancer Institute Common Toxicity Criteria, version 4, and the Response Evaluation Criteria In Solid Tumors, version 1.1. An overall response rate of 86% and a 3-year survival of 65.1% were observed. The median progression-free survival was 32 months. The cumulative incidence after 3 years was 16.9% for local recurrence and 10.4% for distant metastasis. Leukopenia (58%) and anemia (51%) were the most common hematological toxicities, followed by hepatotoxicity (53%) and nausea (27%). A total of 31% of the patients experienced a compromise in their QoL following therapy completion. In conclusion, docetaxel in combination with cisplatin and 5-fluorouracil was found to effectively prolong survival in patients with locally advanced and/or recurrent metastatic SCCHN. The overall survival, progression-free survival and response rates were in accordance with those reported by previous clinical trials. Therefore, this therapy protocol is recommended for patients with SCCHN in the curative as well as the palliative settings.

Abstract
Immunotherapy against head and neck cancer stem cells Immunologic therapies like antibodies in solid tumors like squamous cell cancer of the head and neck are administered either alone or in combination with radiation and chemotherapy. Despite some respectable successes, the effect of this therapy reaches its limits due the ability of the tumor to escape the immune system. Cancer stem cells seem to play an important role in this process due to their intrinsic resistance to conventional therapy and the ability to regenerate tumor heterogeneity. This way they substantially contribute to the formation of recurrences and metastases. Therefore, future immunotherapies should target specifically this subpopulation, possibly in combination with other therapeutic modalities. In this review the immunologic features of cancer stem cells and their potential as target for immunotherapies is summarized.

Abstract
Report of a rare case of severe bleeding from the middle ear cavity after myringotomy. On the basis of the case report, the procedure for such bleeding is discussed in the context of the literature. A 6-year-old boy received a revision myringotomy in an ambulant setting. During the procedure a severe bleeding occurred. The external auditory canal was adequately packed. The patient was extubated and transferred to the clinic as an emergency. Computer tomography of the temporal bone showed the anatomical variant of a dehiscent high jugular bulb, which had been injured. Because no rebleeding occurred, the packing of the ear canal was removed and an explorative tympanoscopy was performed on the third postoperative day. When the tympanomeatal flap was lifted, the defect in the jugular bulb was found. The lesion was covered with Tutopatch® pads and fibrin glue and the auditory canal was packed again. After removal of the packing three weeks postoperatively a properly healed situs was found. No further measures were taken. The injury of a dehiscent jugular bulb in the course of ear surgeries leads to a massive hemorrhage. The case describes the diagnostic and therapeutic procedure for this relatively rare but severe complication.

Abstract
Despite the development of novel multimodal treatment combinations in advanced oropharyngeal squamous cell carcinoma (OSCC), outcomes remain poor. The identification of specifically validated biomarkers is required to understand the underlying molecular mechanisms, to evaluate treatment efficiency and to develop novel therapeutic targets. The present study, therefore, examined the presence of aldehyde dehydrogenase family 1 member A1 (ALDH1A1) and high mobility group box 1 (HMGB1) expression in primary OSCC and analyzed the impact on survival time. In 59 patients with OSCC, the expression of ALDH1A1, p16 and HMGB1, and their clinicopathological data were analyzed. HMGB1 positivity was significantly increased in patients with T1-2 stage disease compared with T3-4 stage disease (P<0.001), whereas ALDH1A1 positivity was not. ALDH1A1+ tumors showed significantly lower differentiation than ALDH1A1- tumors (P=0.018). Multivariate analysis showed that ALDH1A1 positivity (P=0.041) and nodal status (N2-3) (P=0.036) predicted a poor prognosis. In this patient cohort, ALDH1A1 and nodal status were identified as independent predictors of a shorter overall survival time. The study results, therefore, provide evidence of the prognostic value of ALDH1A1 as a marker for cancer stem cells and nodal status in OSCC patients.

Abstract
Adenoid cystic carcinoma (SACC) is a rare malignancy, but a frequent subtype in minor and major salivary glands. The molecular alterations or biomarkers that underlie its development and progression as well as therapy outcomes are poorly characterized. The main study goal was to investigate reliable biomarkers and patient-related factors that may have impact on recurrence and long-term survival of SACC. The prevalence of human papilloma virus (HPV) in SACC was determined by HPV-DNA genotyping and p16 immunostaining. Epithelial growth factor receptor (EGFR), p53 and Ki-67 expression were also evaluated. Twenty-eight (42%) of 67 patients were HPV-DNA positive. Kaplan-Meier analysis indicated that SACC patients with metastases (P=0.03) had a poor overall survival (OS) and a shorter recurrence-free survival (P<0.001). Positive resection margins significantly predicted shorter recurrence-free survival (P=0.01). In the multivariate analysis, non-metastatic disease (P=0.033) and p16 positivity (P=0.005) have shown their prediction value for OS while non-metastatic disease (P=0.002), HPV positivity (P=0.041) and negative resection margin predicted a better recurrence-free survival. The present study documents for the first time the positivity for HPV infection and overexpression of certain markers (p16, Ki-67, EGFR and p53) used in diagnostics in SACC as well as characterizes clinical entities. These factors might be exploited in the future as biomarkers for its prognostic value. Using the clinical and pathological basis for predicting different outcomes could significantly facilitate SACC stratification and potentially directing treatment.

Abstract
The stigma of nasal deformity due to a congenital cleft lip-palate has an undeniable influence on the affected patient's life. It is therefore of interest to investigate if efforts to reduce esthetic and functional impairments by rhinoplasty (single or multiple) can result in an increased satisfaction with appearance and a self-perception similar to the noncleft population. Retrospective scoring before and after rhinoplasty using the validated Derriford Appearance Scale (DAS-59) and subsequent statistical evaluation and comparison to datasets available in the literature for further classification was used. Of the 61 patients who underwent at least one rhinoplasty, 26 responded to all questions. The mean age of responders was approximately 30 years of age and the male:female ratio was 1:1.2. The scale showed a significant overall improvement after surgery. The full scale and all subscale scores of the DAS-59 were significantly reduced after surgery demonstrating an improvement in the respective categories. Most importantly, if postoperative results were compared with a population concerned and unconcerned about appearance, no difference "facial self-consciousness" of appearance was apparent. Also postoperative subscores for "general self-consciousness" (GSC) and "social self-consciousness" of appearance (SSC) showed no difference from those obtained from the population concerned about appearance. The postoperative subscore for "sexual and bodily self-consciousness" of appearance (SBSC) indicated improvement beyond the level found in the concerned control population. Due to only a low improvement in the difference compared with the subscore representing a "negative self-concept," a statistically significant difference to the concerned population remained, possibly indicating that therapy beyond surgery is needed for improvement. After rhinoplasty, the investigated group of cleft lip-palate patients with nasal deformities showed an improvement in their self-conceived appearance as measured by the DAS-59. Their assessment of self-appearance was comparable to that of a group of noncleft persons with concern about their appearance. Taken together, rhinoplasties, primary and revision, add to the psychosocial well-being and an improved self-perception enhancing quality of life and enabling a more normal life. Further research is needed to clarify how the low reduction found in the "negative self-concept" may be addressed successfully.

Abstract
OBJECTIVES To assess the quality of ORL training in France and hierarchical relationships, working conditions and quality of life, based on a questionnaire answered by ORL residents and fellows. MATERIAL AND METHODS The anonymous questionnaire covered the following topics (106 questions): structure of training, supervision by superiors, involvement in teaching medical students, work for publication, working conditions, quality of life and practical and surgical skills. RESULTS One hundred and seventeen questionnaires were included, with 56% female respondents and 78% resident respondents. A total of 80% of respondents would choose the same training again, with overall satisfaction of 70%. In total, 71% felt appreciated, with responsibilities matching their level of training (85%). Supervisors were supportive (85%) and showed good teaching ability (92%). Residents were mainly guided by fellows (70%), or consultants (60%). Providing good training was an important aim for the training structures (78%). Respondents worked 11 hours per day, with a median of 4 duties per month; the post-duty rest-day was fully respected in the case of 38% of respondents. Surgical procedures were taught and delegated step by step, shared fairly between residents, in a large majority of cases. Training progression was in line with seniority. CONCLUSIONS Overall satisfaction, quality and supervision of ORL training were good in France. There remain geographical differences in terms of theoretical and surgical training.

Abstract
BACKGROUND Liver transplant recipients have an increased risk of developing de novo malignancies. METHODS We conducted a prospective evaluation of clinicopathological data and predictors for overall survival (OS) in patients with head and neck squamous cell carcinoma (HNSCC) after liver transplantation (1988 to 2010). RESULTS Thirty-three of 2040 patients who underwent liver transplantation (1.6%) developed de novo HNSCC. The incidence of HNSCC in liver transplant recipients with end-stage alcoholic liver disease (26) was 5%. After a median follow-up of 9 years, 1-year, 3-year, and 5-year OS rates were 74%, 47%, and 34%, respectively. Tumor size, cervical lymph node metastases, tumor site, and therapy (surgery only vs surgery and adjuvant radiotherapy [RT]/chemoradiotherapy [CRT] vs RT/CRT only; p < .0001) were significantly associated with OS in univariate analysis. However, surgery only predicted OS independently in multivariate analysis. CONCLUSION Early diagnosis and surgical treatment of de novo HNSCC are crucial to the outcome. HNSCC risk should be taken into close consideration during posttransplantation follow-up examinations, especially among patients with a positive history of smoking and alcohol consumption.

Abstract
BACKGROUND The objective of this study was to compare the efficacy and safety of taxane (docetaxel or paclitaxel), cisplatin, and fluorouracil (Tax-PF) with cisplatin plus fluorouracil (PF) regimen by a meta-analysis of data retrieved from the literature. METHODS Seven randomized clinical trials were identified, which included patients with advanced head and neck cancer who underwent induction chemotherapy with either a Tax-PF or PF protocol. The outcomes included the 3-year and 5-year overall survival (OS) and progression-free survival (PFS), overall response rate (ORR) and different types of adverse events. RESULTS The 3-year OS rate (HR: 1.14; 95% CI: 1.03 to 1.25; P = 0.008), 3-year PFS rate (HR: 1.24; 95% CI: 1.08 to 1.43; P = 0.002), 5-year OS rate (HR: 1.30; 95% CI, 1.09 to 1.55;P = 0.003), 5-year PFS rate (HR: 1.39; 95% CI, 1.14 to 1.70; P = 0.001) and ORR to chemotherapy (OR 1.66; 95% CI, 1.35 to 2.05; P < 0.001) of the patients in the Tax-PF group were statistically superior to those in the PF group. In terms of toxicities, the incidence of febrile neutropenia (OR 2.36; 95% CI, 1.62 to 3.46; P < 0.001), alopecia (OR 8.22; 95% CI, 3.99 to 16.92; P < 0.001), diarrhea (OR 1.57; 95% CI, 1.05 to 2.36; P = 0.03) and leukopenia (OR 2.79; 95% CI, 1.86 to 4.21; P < 0.001) was higher in the Tax-PF group. CONCLUSION The Tax-PF induction chemotherapy improved PFS and OS, and the ORR was better as compared to PF-based therapy regimens at the cost of a higher incidence of adverse events.

Abstract
Retropharyngeal haematoma (RH) is an extremely rare but potentially life-threatening condition that requires an early diagnosis and immediate management. Acute complications arise from compression and obstruction of the upper airway and oesophagus with the risk of consecutive aspiration. We present the case of a 48-year-old man with formation of a RH after accidental ingestion of a large fish bone with hypertension as comorbidity caused by a so far undiagnosed pheochromocytoma. The patient presented with acute onset of retropharyngeal pain, dysphonia and dysphagia secondary to fish bone foreign body ingestion. His medical history was significant for uncontrolled hypertension. CT showed a large RH extending from the oropharynx to the superior mediastinum. The patient underwent emergency tracheostomy, surgical debridement and removal of the fish bone. Antihypertensive medication was utilised to control his labile blood pressure. The postoperative CT scan revealed an adrenal pheochromocytoma that was subsequently resected.

Abstract
Patient-derived xenograft (PDX) models have shown to reflect original patient tumors better than any other preclinical model. We embarked in a study establishing a large panel of head and neck squamous cell carcinomas PDX for biomarker analysis and evaluation of established and novel compounds. Out of 115 transplanted specimens 52 models were established of which 29 were characterized for response to docetaxel, cetuximab, methotrexate, carboplatin, 5-fluorouracil and everolimus. Further, tumors were subjected to sequencing analysis and gene expression profiling of selected mTOR pathway members. Most frequent response was observed for docetaxel and cetuximab. Responses to carboplatin, 5-fluorouracil and methotrexate were moderate. Everolimus revealed activity in the majority of PDX. Mutational profiling and gene expression analysis did not reveal a predictive biomarker for everolimus even though by trend RPS6KB1 mRNA expression was associated with response. In conclusion we demonstrate a comprehensively characterized panel of head and neck cancer PDX models, which represent a valuable and renewable tissue resource for evaluation of novel compounds and associated biomarkers.

Abstract
BACKGROUND Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer worldwide. HNSCC is caused by persistent high-risk human papillomavirus (HR-HPV) infection or excessive consumption of alcohol or tobacco. The persistently low survival rates result from local recurrences and metastases, which are probably caused by so-called tumor stem cells (TSCs). The epithelial-mesenchymal transition (EMT) or transformation is a key event in metastasis initiation and is being increasingly associated with TSCs. OBJECTIVES This review describes new therapeutic targets in HNSCC, focusing on the TSC hypothesis and EMT regulation. MATERIALS AND METHODS, RESULTS TSCs and EMT are regulated directly and indirectly via transcription factors and microRNAs (miRNAs). These miRNAs regulate multiple cellular processes and may serve as new therapeutic targets, whose modulation could increase the effectiveness of HNSCC treatments. Post-transcriptionally, miRNAs regulate transcription factors associated with EMT (ZEB1/2, EZH2, Bmi-1), tumor suppressors (p53), TSC markers (ALDH, CD44, EpCAM, p63) and both epithelial (E-cadherin) and mesenchymal markers (vimentin). CONCLUSION Alterations in HNSSC TSC miRNA expression before and after chemotherapy could potentially serve as a therapeutic control. In the long term, knowledge of a patient's individual protein expression pattern may permit application of specific chemotherapy. Such individualized therapy might prohibit the development of metastases and potentially unresectable recurrences with a high resistance to radiation and chemotherapy, thus improving the prognosis in HNSCC patients.

Abstract
Background p16INK4a is a tumor suppressor protein which is induced in cells upon the interaction of high-risk HPV E7 with the retinoblastoma protein by a positive feedback loop, but cannot exert its suppressing effect. Previous reports suggested that p16INK4a immunostaining allows precise identification of even small CIN or cervical cancer lesions in biopsies. The prognostic value of overexpressed p16INK4a in cervical cancer has been evaluated for several years while the results remain controversial. We performed a systematic review and meta-analysis of studies assessing the clinical and prognostic significance of overexpression of p16INK4a in cervical cancer. Methods Identification and review of publications assessing clinical or prognostic significance of p16INK4a overexpression in cervical cancer until March 1, 2014. A meta-analysis was performed to clarify the association between p16INK4a overexpression and clinical outcomes. Results A total of 15 publications met the criteria and comprised 1633 cases. Analysis of these data showed that p16INK4a overexpression was not significantly associated with tumor TNM staging (I+II vs. III+IV) (OR = 0.75, 95% confidence interval [CI]: 0.35–1.63, P = 0.47), the tumor grade (G1+ G2 vs. G3) (OR = 0.78, 95% CI: 0.39–1.57, P = 0.49), the tumor size (<4 vs. ≥4 cm) (OR = 1.10, 95% CI: 0.45–2.69, P = 0.83), or vascular invasion (OR = 1.20, 95% CI: 0.69–2.08, P = 0.52). However, in the identified studies, overexpression of p16INK4a was highly correlated with no lymph node metastasis (OR = 0.51, 95% CI: 0.28–0.95, P = 0.04), increased overall survival (relative risk [RR]: 0.42, 95% CI: 0.24–0.72, P = 0.002) and increased disease free survival (RR: 0.60, 95% CI: 0.44–0.82, P = 0.001). Conclusions This meta-analysis shows overexpression of p16INK4a in cervical cancer is connected with increased overall and disease free survival and thus marks a better prognosis.

Abstract
MicroRNAs (miRs) are small non-coding RNAs that regulate the translation of many genes in normal and cancer cells where they are frequently dysregulated promoting tumor progression. Several studies have illustrated the potential of manipulating miR expression in cancer research and therapy. The aim of the present study was to investigate expression patterns of a panel of miRs in head and neck squamous cell carcinoma (HNSCC) shown to be relevant in other carcinomas and to elucidate their role if dysregulated. We performed analysis of miR‑21, -200c, -138-1, -138-2, -25 and -34 expression by qRT-PCR in 6 HNSCC cell lines and computerized search for genetic targets of dysregulated miRNA-21 (miR‑21). Lipofection of mock and anti-miR-21 and determination of expression efficiencies and final programmed cell death 4 (PDCD4) expression were carried out by luciferase assay and western blotting. MTT assay was used to measure cell proliferation and flow cytometry was performed for cell cycle analysis. Expression of miR-21 was most prominently upregulated in the HNSCC cell lines, particularly in UM-SCC11B (6.45±0.25-fold, P<0.05) and UM-SCC9 (4.35±0.22-fold, P<0.05) as compared to primary epidermal keratinocytes used as control. The expression levels of the other miRs showed no difference except for miR-34 and -138-1 each in one cell line. Subsequent transfection of precursor miR-21 stimulated proliferation while anti-miR-21 inhibited proliferation of both cell lines. PDCD4 was identified with software designed for this purpose as potential target gene of miR-21. Subsequently, its role in HNSCC lines was experimentally confirmed by regulation of PDCD4 transfecting miR-21 mimics and anti-miR-21. Finally, we showed that PDCD4 is negatively regulated by miR-21 at the post-transcriptional level via binding to the 3'-untranslated region of PDCD4 mRNA. A role of upregulated miR-21 and reduced PDCD4 stimulating the proliferation was demonstrated in HNSCC lines and, in turn, transfection of anti-miR-21 upregulating PDCD4 reduced the cellular division rate. We explored miR-21 and PDCD4 expression as markers of progression and prognosis and for a potential translational value in the development of agents slowing growth of HNSCC and other carcinomas useful in palliative therapy or as a component of multi-modality treatments.

Abstract
With the coalescing of Europe, increased mobility of professionals emerges. Initiatives to harmonize medical education were launched. In Otolaryngology, Head and Neck surgery (ORL) an European board examination was created to ensure standards. Quality of training, satisfaction and quality of life of residents and recent ORL specialists were compared to assess different aspects of work and hierarchical relationships in France (FRA) and Germany (GER) by means of an anonymous questionnaire. 120 FRA and 125 GER questionnaires were included. 78 % of respondents were residents. 86 % would choose the same training again. In both countries, a majority felt well considered with responsibilities adapted to their level of training and with supportive supervisors. Germans reported average daily work hours of 9.6 versus 11 in FRA with compensated overtime (76 %) and a possibility of part-time work (62 %), both nearly inexistent in FRA. In GER, the day-off after duty was more often respected. French attributed their seniors better pedagogic skills, taking time for explanations and providing better teaching. Offering a good training was a more important objective in French training centers (77 vs. 51 %). In both countries, surgical training relied on coaching. Research activities were comparable. The overall satisfaction with ORL training was high. Differences concerned structure of training, guidance by senior doctors and the working conditions. The study results provide guidance before choosing a program and may help to improve current training by identifying positive aspects that, if combined could lead to a convergence of programs. However, present high standards of education must be maintained.

Abstract
Despite optimized therapeutic strategies, the long-term survival of head and neck squamous cell carcinomas (HNSCC) has improved in recent years only slightly. Most studies on the tumor cell genome focus on protein-coding genes (exons). Data on changes within the non-coding sequences (introns) are limited. miRNAs (microRNA, miR) are small non-coding single-stranded RNAs that control gene expression at the posttranscriptional level by interacting with the mRNA. miRNA functions include many biological processes and control up to 50 % of human genes. They can have oncogenic or tumor suppressive functions. Altered expression patterns of miRNAs are involved in carcinogenesis and tumor progression even in HNSCC, or those processes (increased resistance to radiation or chemotherapy) that could be responsible for the poor long-term prognosis by forming metastases and inoperable local recurrences. Therefore, we here present miRNA groups, which are involved in these processes and may serve as new potential therapeutic treatment targets. miRNAs may also serve as biomarkers for early diagnosis, evaluation and monitoring of treatment and tumor recurrence. Alterations in miRNA expression before and after chemotherapy are therefore of high interest. In the long run, this knowledge could lead to more effective therapies with improved therapeutic outcome of HNSCC.

Abstract
Oropharyngeal squamous cell carcinoma (OSCC) is caused by high-risk (HR) human papillomavirus (HPV) or alcohol and tobacco abuse. Aldehyde dehydrogenase 1 (ALDH1) is a confirmed marker for cancer stem-like cells (CSCs) of OSCC responsible for therapy resistance, recurrence and metastasis. Associations between HR-HPV/p16, CSC frequency and clinicopathological parameters in patients with metastatic OSCC were investigated. In the present study, HPV genotypes and expression of ALDH1 and p16 was analyzed in 40 paired OSCC and metastases. A significant correlation between ALDH1 positivity with lower primary tumor differentiation grade (P=0.009) and higher nodal status (P=0.015) was noted. Compared to primary tumors, the proportion of ALDH1-expressing cells was significantly increased in metastases (P=0.012), while significantly fewer ALDH1-expressing cells were found in HR-HPV-DNA⁺/p16⁺ primary tumors (P=0.038) compared to HR-HPV-DNA⁻/p16⁻ primary tumors. Metastases showed no difference. ALDH1⁺ CSCs are detectable in OSCC and metastases. ALDH1 high-grade OSCC exhibits a more aggressive phenotype characterized by higher nodal classification and lower differentiation. This suggests a subpopulation contained in the ALDH1-positive OSCC cell pool able to complete the metastatic cascade and subsequently enriching in metastasis independent of tumor etiology and ALDH1 content.

Abstract
The initiation, growth, recurrence and metastasis of head and neck squamous cell carcinomas (HNSCC) and other cancers have recently been related to the presence of cancer stem cells (CSC). Cancer stem cells have some characteristics in common with tissue stem cells like unlimited self renewal and the expression of stem cell factors. CSC express specific markers that vary considerably depending on tumor type or tissue of origin--the discovery of an universal marker has not yet been made. Compared to the bulk tumor mass, CSC are less sensitive to chemo- and radiotherapy and also have a lower immunogenicity. Another concept that explains the seeding of metastases is the epithelial-mesenchymal transition of CSC. CSC-targeted therapies may change the prognosis of patients with HNSCC in the future. Recent knowledge on the role of CSC in HNSCC is reviewed, and known CSC markers as well as possible therapeutic targets are described.

Abstract
The initiation and metastasis of head and neck squamous cell carcinomas (HNSCC) and other cancers have recently been related to the presence of cancer stem cells (CSC). CSC are cancer initiating, sustaining and are mostly quiescent. Specific markers that vary considerably depending on tumor type or tissue of origin characterize putative CSC. Compared to the bulk tumor mass, CSC are less sensitive to chemo- and radiotherapy and may also have low immunogenicity. Therapeutic targeting of CSC may improve clinical outcome of HNSCC which has two distinct etiologies: infection of epithelial stem cells by high-risk types of the human papillomavirus, or long-term tobacco and alcohol abuse. Recent knowledge on the role of CSC in HNSCC is reviewed and where necessary parallels to CSC of other origin are drawn to give a more comprehensive picture.

Abstract
OBJECTIVE To establish the methods for purification, culture, and identification of adult human skeletal muscle stem cells in vitro and to explore the biological properties of the cells. METHODS Muscle stem cells were obtained by reformed enzymatic digestion of muscle tissue from the consenting donors and cultured in serum-free medium. The morphology was inspected by an inverted phase contrast microscope. Phenotypic characteristics of the cells and expression of cell-specific markers were determined using reverse transcription-polymerase chain reaction (RT-PCR) and immunocytochemistry. The growth of single cells in suspension culture was observed and recorded continuously. The cells were analyzed for their multi-lineage differentiation potential into osteoblastic, adipocyte, and smooth muscle cell lineages. RESULTS Primary cultured human skeletal muscle stem cells proliferated and formed the big spheres when cultured with serum free medium. Immunofluorescence staining displayed Pax7 and ALDH1 positive expression in the cell spheres. Furthermore, Myod and Desmin showed positive expression in the monolayer cells derived from the spheres. The gene expressions of Oct3/4, Nanog, Sox2 and Pax7 in the cells were determined by RT-PCR. The cell clones formed from single cells grew well. In addition, they were capable of spontaneous differentiation into myotubes in differentiation medium and into other mesodermal cell lineages in induction medium. CONCLUSIONS Human muscle stem cells with properties of self-renewal capacity and multi-differentiation could be successfully isolated and expanded in vitro.

Abstract
BACKGROUND Recent studies have suggested that caveolin-1 (cav-1) plays an important role in the regulation of transforming growth factor (TGF)-β1 signalling and participates in the pathogenesis of tissue fibrosis. However, its effects on dermal fibrosis keloids are unknown. OBJECTIVES To investigate the effect of cav-1 in the pathogenesis of tissue fibrosis by keloid fibroblasts. METHODS Keloid fibroblasts were cultured and exposed to different concentrations of cav-1 cell-permeable peptides (cav-1p) in the presence of TGF-β1. Keloid fibroblast phenotypes and protein production were analysed by real-time reverse transcriptase-polymerase chain reaction, Western blot, and multiplex enzyme-linked immunosorbent assay techniques. The effect of cav-1p on cell viability was evaluated by MTT assay. RESULTS Cav-1 was markedly decreased in the keloid-derived fibroblasts. Moreover, cav-1p significantly reduced TGF-β receptor type I levels and Smad2/3 phosphorylation in response to added TGF-β1. Additionally, TGF-β1 decreased cav-1 expression in human skin fibroblasts. Cav-1 was able to suppress TGF-β1-induced extracellular matrix production in cultured keloid fibroblasts through regulation of the mitogen-activated protein kinase pathway. CONCLUSIONS Cav-1 appears to participate in the pathogenesis of tissue fibrosis in keloid. Restoration of cav-1 function by treatment with a cell-permeable peptide corresponding to the cav-1 scaffolding domain may be a novel therapeutic approach in keloid.

Abstract
Initiation, growth, recurrence, and metastasis of head and neck squamous cell carcinomas (HNSCC) have been related to the behavior of cancer stem cells (CSC) that can be identified by their aldehyde-dehydrogenase-isoform-1 (ALDH1) activity. We quantified and enriched ALDH1+ cells within HNSCC cell lines and subsequently characterized their phenotypical and functional properties like invasion capacity and epithelial-mesenchymal transition (EMT). Spheroid culture enriched CSC from five HNSCC cell lines by up to 5-fold. In spheroid-derived cells (SDC) and the parental monolayer-derived cell line ALDH1, CD44, CD24, E-Cadherin, α-SMA, and Vimentin expression was compared by flow-cytometry and immunofluorescence together with proliferation and cell cycle analysis. Invasion activity was evaluated by Matrigel assay and expression of stemness-related transcription factors (TF) Nanog, Oct3/4, Sox2 and EMT-related genes Snail1 and 2, and Twist by real-time PCR. All cell lines formed spheroids that could self-renew and be serially re-passaged. ALDH1 expression was significantly higher in SDC. ALDH1+ cells showed increased colony-formation. The proportion of cells with a putative CSC marker constellation of CD44+/CD24− was highly variable (0.5% to 96%) in monolayer and spheroid cultures and overlapped in 0%–33% with the CD44+/CD24−/ALDH1+ cell subset. SDC had significantly higher invading activity. mRNA of the stemness-related genes Sox2, Nanog, and Oct3/4 was significantly increased in SDC of all cell lines. Twist was significantly increased in two while Snail2 showed a significant increase in one and a significant decrease in SDC of two cell lines. SDC had a higher G0 phase proportion, showed high-level expression of α-SMA and Vimentin, but significantly decreased E-Cadherin expression. HNSCC-lines harbor potential CSC, characterized by ALDH1 and stemness marker TF expression as well as properties like invasiveness, quiescence, and EMT. CSC can be enriched by anchorage-independent culture techniques, which may be important for the investigation of their contribution to therapy resistance, tumor recurrence and metastasis.

Abstract
Nucleotide excision repair (NER) is a key node of resistance of tumour cells to the anticancer drug cisplatin. Testicular germ cell tumours (TGCT) show exquisite sensitivity towards cisplatin, and this has been connected to low levels of the NER proteins ERCC1 and XPF. Tumours of some patients with advanced head and neck squamous cell carcinoma (HNSCC) regress well under cisplatin chemotherapy but prediction of responsiveness is poor. Little is known about the levels of ERCC1-XPF in HNSCC tissues and cell lines. We investigated mRNA and protein levels of ERCC1 and XPF in 13 HNSCC cell lines and seven testis tumour cell lines and examined the correlation between levels of ERCC1 and XPF and cellular resistance towards cisplatin. No significant difference in mRNA expression of either ERCC1 or XPF in the HNSCC cell lines compared to the testis tumour cell lines was observed. Significantly higher XPF protein levels were found in HNSCC cell lines compared to testis tumour cell lines resulting in cellular cisplatin resistance. The data indicate a contribution of XPF protein for the cisplatin resistance observed in HNSCC cell lines. Subsequently, XPF and ERCC1 protein expression was investigated in cancer tissue of 34 patients. XPF levels were significantly higher in metastases of HNSCC patients than in primary cancer tissue. These findings indicate a contribution of XPF protein for the observed chemoresistance in some HNSCC tissue. XPF protein may be a predictive marker for cisplatin responsiveness of metastases in HNSCC patients.

Abstract
Background Systemic treatment of head and neck squamous cell carcinoma (HNSCC) includes a variety of antineoplastic drugs. However, drug-resistance interferes with the effectiveness of chemotherapy. Preclinical testing models are needed in order to develop approaches to overcome chemoresistance. Methods Ten human cell lines were obtained from HNSCC, including one with experimentally-induced cisplatin resistance. Inhibition of cell growth by seven chemotherapeutic agents (cisplatin, carboplatin, 5- fluorouracil, methotrexate, bleomycin, vincristin, and paclitaxel) was measured using metabolic MTT-uptake assay and correlated to clinically-achievable plasma concentrations. Results All drugs inhibited cell growth in a concentration-dependent manner with an IC50 comparable to that achievable in vivo. However, response curves for methotrexate were unsatisfactory and for paclitaxel, the solubilizer cremophor EL was toxic. Cross-resistance was observed between cisplatin and carboplatin. Conclusion Chemosensitivity of HNSCC cell lines can be determined using the MTT-uptake assay. For DNA-interfering cytostatics and vinca alkaloids this is a simple and reproducible procedure. Determined in vitro chemosensitivity serves as a baseline for further experimental approaches aiming to modulate chemoresistance in HNSCC with potential clinical significance.

Abstract
A 65-year-old patient presented with extensive swelling of the lateral neck. B-mode ultrasound showed an oval, well defined, hypoechoic formation consisting of multiple circular layers extending from the base of the skull to the subclavian vein. On subsequent computed tomography the size of the lesion was confirmed and the cause, a mediastinal mass compressing the superior caval vein, was identified. Histological examination of the mass revealed a neuroendocrine active non-small-cell-cancer of the lung. Treatment with high-dose heparin and antibiotics was started immediately, combined with palliative chemotherapy.The differential diagnosis of neck masses includes congenital, infectious, neoplastic and secondary causes due to disease in other regions of the body. Etiologies for jugular vein thrombosis include prolonged central venous catheterization, trauma, obstruction, infection as well as hypercoagulation. In order to diagnose masses in the head and neck region, other parts of the body need to be successively included if no local cause can be identified.
