The treatment landscape for HPV-negative HNSCC has historically been limited to surgery, radiation, and chemotherapy, with these modalities often yielding suboptimal outcomes. The emergence of advanced immunotherapy represents a paradigm shift, offering new therapeutic options for this challenging cancer type. This review provides a comprehensive analysis of the latest advancements in immunotherapy for HPV-negative HNSCC, focusing on, chimeric antigen receptor (CAR) T-cell therapy, therapeutic cancer vaccines and immune checkpoint inhibitors. It also explores the potential benefits and limitations of combining immunotherapy with other treatment modalities including chemotherapy, targeted therapy, and radiation. Key challenges, including tumor heterogeneity, immunosuppressive microenvironment, and resistance mechanisms, are discussed. The review concludes with a look at future research directions and strategies to overcome these challenges and improve patient outcomes.</div></div>","PeriodicalId":94378,"journal":{"name":"Oral Oncology Reports","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142441447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We address how interactions within the TME lead to tumor growth, treatment resistance, and immune evasion, focusing on current clinical studies that target these processes. In addition, we evaluate emerging therapeutic methods, such as immune checkpoint inhibitors, CAR-T cell therapy, anti-angiogenic medicines, and ECM remodeling inhibitors, which have shown promise in clinical trials. Despite the obstacles faced by TME heterogeneity and the requirement for robust biomarkers, personalized medicine approaches based on TME profiling hold great promise for improving treatment results.

At the heart of this approach is the use of comprehensive multi-omics data to improve patient management by tailoring interventions to individual molecular profiles. This two-way flow not only optimizes treatment based on real-time insights from molecular pathways, but also improves the application of GWAS results in clinical scenarios. Advanced computational tools such as machine learning and network analysis are critical for navigating these complex data sets and translating intricate molecular data into actionable treatment plans.

This paper has comprehensively updated the guidelines on sampling methods and sample size calculation, hence giving enough evidence that will be beneficial in assisting researchers to advance the credibility and statistical power of their research work. The differences between probability sampling techniques, including simple random sampling, stratified sampling, and cluster sampling, and non-probability methods, such as convenience sampling, purposive sampling, and snowball sampling, have been fully explained. Probability is the only that can ensure the generalizability, while non-probability sampling is useful in exploratory situations. Another significant process is the determination of an optimal sample size, which, among other things, has to take into account the total population size, effect size, statistical power, confidence level, and margin of error. The paper contributes both theoretical guidance and practical tools that researchers need in choosing appropriate strategies for sampling and validating methodologically appropriate sample size calculations.
