Project description:Human papillomavirus (HPV) positive HNSCC patients generally have a favorable survival and promising responsiveness to radiotherapy, chemoradiotherapy and checkpoint blockades. However, HPV negative patients, the majority of HNSCC patients, have been largely overlooked. Cell death has been involved in the therapeutic resistance of cancers. We constructed a cell death index (CDI), based on autophagy, apoptosis and pyroptosis related genes, to predict the prognosis for HNSCC using TCGA dataset, and validated in a cohort from Qilu Hospital of Shandong University. We performed RNA sequencing of 28 paraffin-embedded tissue from HNSCC patients and determined HPV status by immunohistochemistry of p16. We found that CDI was an independent prognostic indicator for overall survival. Notably, the prognostic value of CDI was more profound in HPV negative HNSCC patients compared with those with HPV positivity.

Project description:Head and neck squamous cell carcinomas are heterogeneous neoplasms that show clinical and biological differences in association with the human papillomavirus (HPV). To provide adequate therapeutic strategies, biological and clinical characterization is essential to stratify patients based on prognostic and predictive factors. Reports on HNSCC are scarce in Mexico, thus in the present study, we analyze 414 cases of HNSCC, including those of the oropharynx (OPSCC), larynx (LASCC), and oral cavity (OCSCC). We determined the presence of HPV and p16 expression. Global expression profiles were analyzed with Affymetrix HTA 2.0 microarray in 25 selected cases HPV+/p16+ versus HPV-/p16-. In our study we analyze 25 samples derived from HNSCC patients. 18 samples were HPV-/p16- and 7 HPV+/p16+. We compared the HPV-/p16- versus the HPV+/p16+ and identified differentially expressed RNAs with a fold change greater than 1.5 or less than -1.5. These data were used to obtain 98 genes that are differentially expressed in absence of HPV. The present study offers information regarding clinical and molecular characteristics of HNSCC, both associated and unassociated with HPV, in Mexican patients.

Project description:The risk of locoregional or distant failure in advanced HPV-negative head and neck squamous cell carcinoma (HNSCC) patients is high. However, no suitable markers for stratification are clinically available. Thus, we aimed to identify a microRNA(miRNA)-signature predicting disease recurrence. For this purpose the miRNA profiles from 162 HNSCC samples were analysed with regard to identification of a low-complex porgnostic signature. The data set consists of a discovery dataset (n=85) and a validation dataset (n=77). The study resulted in a prognostic 5-miRNA signature significantly predicting the relevant clinical endpoint freedom from recurrence.

Project description:Head and neck cancer (HNC) is the fifth most common malignancy worldwide with an annual mortality rate of 200,000. About 90% of HNC can be classified as head and neck squamous cell carcinomas (HNSCC), of which approximately 75% are attributed to alcohol and tobacco consumption and 25 are associated with human papillomavirus (HPV), predominantly HPV16. HPV-associated OPC have better prognosis and a more favorable response to therapy as compared to HPV-negative tumors. Differences in risk factors, age of presentation, clinical behavior and gene expression profiles indicate that HPV-positive and HPV-negative tumors develop via different molecular mechanisms and are biologically distinct. HPV has been characterized as a risk factor for OPC based on race, life style and sexual behavior, impacting survival outcomes for both African American (AA) and European American (EA) patients. According to some reports, the rate of HPV-associated tumors is much lower in AA patients as compared to EA patients in United States. In general, however, AA males have a higher incidence of HNC than any other racial/gender group, and a mortality rate almost three-fold that observed in EA males. Overall, AA patients tend to present with more HPV-negative OPC and have worse prognosis as compared to both HPV-positive and HPV-negative EA patients. This study aimed to compare the gene expression profiles of HPV-negative oropharyngeal squamous cell carcinoma (OPC) and normal benign uvula/tonsil tissues from European American patients and determine what biological processes and pathways are affected in HPV-negative OPCs in EA patients. Additional datasets in this study explore gene expression differences in HNC from EA and AA patients. ANALYSIS 8: Two-condition, one-color experiment: European American (EA) HPV-negative oropharyngeal tumor samples and normal benign uvula/tonsil tissues. Biological replicates: 8 EA HPV active samples and 4 EA Normal samples.

This study aimed to compare the gene expression profiles of HPV-negative HNSCC from AA and EA patients, and determine their biological differences.

Project description:Background: Oropharynx squamous cell carcinoma (OPSCC) is a subtype of HNSCC, arising from the base of tongue, lingual tonsil, tonsil, oropharynx, pharynx. The majority of OPSCC positive for HPV infection is associated with better prognosis, but a fraction of them, similarly to HPV-negative ones, is resistant to therapy and has poor prognosis. A deep molecular study of OPSCC is mandatory to identify either prognostic markers or targets for therapy, in particular in patients with worse prognosis. Methods: 14 HPV-positive and 15 HPV-negative Italian OPSCC (n=29) with complete clinical information and follow-up of more than 5 years were molecularly characterized by gene expression profiling and compared to three cohorts of OPSCC extracted from public HNSCC datasets. AKR1C3 emerged as robust marker overexpressed in HPV-negative OPSCC and in HPV-positive lesions with worse prognosis. Fadu and Cal-27 OPSCC cell lines were treated with AKR1C3 inhibitors, alone or in combination with Cisplatin. Results: Gene set enrichment analysis revealed that up-regulated genes in HPV-positive samples are involved in immune system, muscle related processes, response to stimuli, actin organization, tissue development and adhesion, while down-regulated genes participated in glutathione derivative biosynthetic and xenobiotic metabolic processes, hypoxia and oxidative stress. AKR1C3, coding for an enzyme involved in chemio-radioresistance, is in the top10 genes with higher upregulation in HPV-negative samples. Pre-treatment with a selective AKR1C3 inhibitor potentiated the effect of Cisplatin in cells with higher basal level of the enzyme. Conclusions: We identified a druggable target, AKR1C3, associated with survival in subgroups of OPSCC patients either positive or negative for HPV infection and to resistance to chemo-radiotherapy in HNSCC. Pretreatment of OPSCC cell lines expressing this enzyme with a selective AKR1C3 inhibitor is able to enhance Cisplatin efficacy.

Project description:ABSTRACT Two major subgroups of head and neck squamous cell carcinomas (HNSCC) are currently distinguished based on etiology and pattern of genetic alterations; tumors with biologically active human papillomavirus (HPV) and tumors without. It is at present unclear whether additional genetically distinct subgroups exist within HPV-negative HNSCC. Aim of this study is to genetically classify HNSCC without HPV involvement and to correlate the genetically defined classes to tumor and patient characteristics. By means of array comparative genomic hybridization (aCGH) we determined DNA copy number variation in thirty-nine HPV-negative, but further unselected HNSCC. Unsupervised analysis of aCGH data distinguished two genetic groups in HPV-negative HNSCC, one characterized by a low level of chromosomal alterations (N=9), and another by a high level of chromosomal alterations (N=30). Absence of chromosomal aberrations was significantly associated with wild-type TP53, a low level of alcohol consumption, a female gender and a better prognosis. The tumors were negative for microsatellite instability. The discovery of this new class of HNSCC with unique genetic and clinical characteristics has important consequences for future basic and clinical studies. All DNAs are isolated from fresh frozen HNSCC specimen. All tissue specimens were microdissected to obtain at least 90% tumor DNA. All sampels are hybridized against a pool of reference DNA of normal individuals of the opposite gender.

Project description:Relapsed head and neck squamous cell carcinoma (HNSCC) unrelated to HPV infection carries a poor prognosis. Novel approaches are needed to improve the clinical outcome and prolong survival in this patient population which has poor long-term responses to immune checkpoint blockade. This study evaluated the chemokine receptors, CXCR1 and CXCR2, as potential novel targets for the treatment of HPV-negative HNSCC. Expression of IL-8, CXCR1, and CXCR2 was investigated in HNSCC tissues and human cell line models. Inhibition of CXCR1/2 with the clinical stage, small molecule inhibitor, SX-682, was evaluated in vitro and in vivo using human xenografts and murine models of HNSCC, both as a monotherapy and in combination with the taxane chemotherapy, docetaxel. High levels of IL-8, CXCR1, and CXCR2 expression were observed in HPV-negative compared to HPV-positive HNSCC tumors or cell lines. Treatment of HPV-negative HNSCC cell lines in vitro with SX-682 sensitized the tumor cells to the cytotoxic activity of docetaxel. In vivo, treatment of HNSCC xenograft models with the combination of SX-682 plus docetaxel led to strong anti-tumor control resulting in tumor cures. This phenomenon was associated with an increase of microRNA-200c and a decreased expression of its target, tubulin beta-3, a protein involved in resistance to microtubule-targeting chemotherapies. In vivo treatment of a murine syngeneic model of HNSCC with SX-682 plus docetaxel led to potent anti-tumor efficacy through a simultaneous decrease in suppressive CXCR2+ polymorphonuclear, myeloid-derived suppressor cells and an increase in cytotoxic CD8+ T cells in the combination therapy treated tumors compared to controls. This study reports, for the first time, mechanistic findings through which the combination of CXCR1/2 inhibition and docetaxel chemotherapy exhibits synergy in models of HPV-negative HNSCC. These findings provide rationale for the use of this novel combination approach to treat HPV-negative HNSCC patients and for future combination studies of CXCR1/2 inhibition, docetaxel, and immune-based therapies.
