Immunotherapeutics for head and neck squamous cell carcinoma stem cells.

Immunotherapeutics for head and neck squamous cell carcinoma stem cells. HNO. 2020 Jan 29;: Authors: Qian X, Leonard F, Wenhao Y, Sudhoff H, Hoffmann TK, Ferrone S, Kaufmann AM, Albers AE 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.

AbstractBackgroundSal-like protein 4 (SALL4), an embryonic stem cell factor, has been reported to play an essential role in embryogenesis and oncogenesis. As yet, however, the expression and role of this transcription factor in head and neck squamous cell carcinoma (HNSCC) has not been established.MethodsWe assessedSALL4 mRNA expression in a well-characterised dataset of 230 HNSCC samples (test cohort 110 cases and validation cohort 120 cases). We also transfected HNSCC cells (FaDu and UM-SCC-6) with SALL4 siRNA and assessed its effects on proliferation and expression of specific epigenetic factors in order to uncover the ...

In this manuscript we compare the expression and applicability of biomarkers, from single genes and gene signatures, identified in patients with locally advanced head and neck squamous cell carcinoma (HNSCC) using the GeneChip Human Transcriptome Array 2.0, nCounter and real-time polymerase chain reaction (RT-PCR) analyses. Two multicentre retrospective HNSCC patient cohorts of the German Cancer Consortium Radiation Oncology Group (DKTK-ROG), who received postoperative radiochemotherapy (PORT-C) or primary radiochemotherapy (primary RCTx) were considered.

In this study, we identified reliable miRNA clusters that can be used to subclassify HNSCC tumors as well as other squamous tumors of other anatomic locations. An institutional discovery cohort was generated using miRNA expression data from microarrays, and this was validated using publicly available next-generation microRNA sequencing data from TCGA. Further analysis of these subtypes revealed distinct biological and clinical features of HNSCC tumors based on the miRNA expression profiles, which provides new insights into the pathogenesis and treatment of HNSCC.

In this study the EGFR over‐expressing human head/neck OSC‐19‐luc2‐cGFP tumour with transfected GFP gen e was used in a skin‐fold window‐chamber model in BALB/c nude mice. The uptake and localization of the conjugate in the tumour and its surrounding normal tissues were studied by an intravital confocal laser scanning microscopy with image analyses. The tumour was also irradiated with 690 nm las er light 24 hours after conjugate administration. The vascular and tumour responses were examined by morphological evaluation and immunohistochemistry (IHC). The amount of conjugate in the tumour peaked at 24‐4...

Abstract BACKGROUND AND PURPOSE: Bilateral elective nodal irradiation (ENI) remains the standard treatment for head and neck squamous cell carcinoma (HNSCC). Unilateral ENI could reduce treatment toxicity and improve health-related quality-of-life (HRQOL). This prospective proof-of-principle trial (NCT02572661) investigated the feasibility, safety and clinical benefits of SPECT/CT-guided ENI of the node-negative contralateral neck. MATERIALS AND METHODS: Patients with lateralized T1-3N0-2bM0 HNSCC of the oropharynx, oral cavity, larynx and hypopharynx underwent SPECT/CT after peritumoral 99mTc-nanocolloid inj...

Conclusion: We found that increasing the number of ctDNA genetic methylations resulted in an increase in diagnostic sensitivity accuracy. No studies investigating ctDNA mutations included a control group. A combination of multiple human ctDNA gene alterations with viral ctDNA are promising tools for developing a ctDNA biomarker for HNSCC. PMID: 32223478 [PubMed - as supplied by publisher]

This study aimed to investigate the association between Arg399Gln SNP and the risk of squamous cell carcinoma of the head and neck. MATERIAL AND METHOD: Ninety nine patients with squamous cell carcinomas of the head and neck and 89 healthy adult controls were enrolled in this study. The Arg399Gln in XRCC1 allele was genotyped using polymerase chain reaction-restriction fragment length polymorphism method. RESULTS: In the single-locus analyses, Arg399Gln SNP showed a significant association with head and neck cancer risk (p value = 0.016 and odd ratio of 1.8). On the genotype level, we applied three analysis models,...
