Releasing the brakes: the role of immune checkpoint inhibitors in laryngeal cancer.

Laryngeal cancer, a subtype of head and neck cancer, poses significant challenges due to its profound impact on essential functions such as speech and swallowing and poor survival rates in advanced stages. Traditional treatments-surgery, radiotherapy, and chemotherapy-are often associated with high morbidity and substantial recurrence rates, emphasizing the urgent need for novel therapeutic approaches. Immune checkpoint inhibitors (ICIs) have revolutionized oncology by countering tumor-induced immune evasion, restoring immune surveillance, and activating T-cell responses against cancer.

Micro-Epigenetic Markers in Viral Genome: SARS-CoV-2 Infection Impact on Host Cell MicroRNA Landscape.

Introduction: MicroRNAs (miRs) are crucial micro-genetic markers that significantly manipulate gene expression in neoplastic/malignant and non-neoplastic diseases, as viral infections. Different expression patterns of miRs seem to partially influence the response rates to specific chemo-targeted therapeutic regimens and prognosis in cancer patients. Concerning their nature, miRs are short non-coding RNAs including 20-25 nucleotides hosted in intra- or intergenic regions.

The Association between Telomere Length and Head and Neck Cancer Risk: A Systematic Review and Meta-Analysis.

Telomeres play a crucial role in maintaining chromosomal integrity and regulating the number of cell divisions and have been associated with cellular aging. Telomere length (TL) has been widely studied in manifold cancer types; however, the results have been inconsistent. This systematic review and meta-analysis aims to analyze the evidence on the association between TL and head and neck cancer (HNC) risk.

C-Jun Transcription Factor Oncogenic Activation in Oral Carcinoma.

Introduction: Oral carcinogenetic is based on a variety of genomic imbalances (gross chromosome or specific gene alterations) that drive the normal oral mucosa to its neoplastic/dysplastic epithelial form and finally to a totally malignant tissue transformation. In this multi-step procedure, down-regulation of suppressor genes combined with overactivation of oncogenes are two crucial and partially early genetic events involved in the onset and progression of neoplastic/malignant epithelia transformation. More specifically, deregulation of strong transcription factors negatively affects the normal expression of a broad spectrum of genes that are involved in cell proliferation and signalling transduction to the nucleus.

Clinical Impact of C-myc Oncogenic Diversity on Solid and Lymphoid Malignancies.

Introduction: Onset and progression of malignant tumors is a multistep process including a variety of gross chromosomal and specific genes' deregulation. Among oncogenes that are frequently altered in solid and also in hematological malignancies, the C-myc (gene locus: 8q24.21) plays a pivotal role.

The Role of Oncogenic Viruses in Head and Neck Cancers: Epidemiology, Pathogenesis, and Advancements in Detection Methods.

Head and neck cancers (HNCs) constitute a wide range of malignancies originating from the epithelial lining of the upper aerodigestive tract, including the oral cavity, pharynx, larynx, nasal cavity, paranasal sinuses, and salivary glands. Although lymphomas affecting this region are not conventionally classified as HNCs, they may occur in lymph nodes or mucosa-associated lymphoid tissues within the head and neck. Oncogenic viruses play a crucial role in HNC onset.

Necrotizing Laryngitis in Patients with Hematologic Disease: The First Case-Report Due to PDR and Literature Review.

Immunocompromised patients with hematologic diseases may experience life-threatening infections with rather uncommon manifestations. Laryngitis has been described as a potential infection in such vulnerable patients and may result in major complications, ranging from impending airway obstruction to total laryngeal necrosis. Immediate laryngoscopy is of paramount importance, as it provides quantification of laryngeal edema and evidence of necrosis.

Intercellular pathways of cancer treatment-related cardiotoxicity and their therapeutic implications: the paradigm of radiotherapy.

Advances in cancer therapeutics have improved patient survival rates. However, cancer survivors may suffer from adverse events either at the time of therapy or later in life. Cardiovascular diseases (CVD) represent a clinically important, but mechanistically understudied complication, which interfere with the continuation of best-possible care, induce life-threatening risks, and/or lead to long-term morbidity.

Insights into metastatic roadmap of head and neck cancer squamous cell carcinoma based on clinical, histopathological and molecular profiles.

The incidence of head and neck cancer (HNC), constituting approximately one in ten cancer cases worldwide, affects approximately 644,000 individuals annually. Managing this complex disease involves various treatment modalities such as systemic therapy, radiation, and surgery, particularly for patients with locally advanced disease. HNC treatment necessitates a multidisciplinary approach due to alterations in patients' genomes affecting their functionality.

Parotid Metastasis of Early-Stage Upper Eyelid Sebaceous Carcinoma: A Case Presentation and a Literature Review.

Metastasis from early-stage sebaceous carcinoma of the eyelid to the salivary glands is considered very rare, occurring in less than 3% of early-stage patients. We report the case of a 72-year-old Caucasian man with a parotid tumor. Fine needle aspiration was consistent with a salivary duct carcinoma.

Pulsed Electromagnetic Fields (PEMFs) Trigger Cell Death and Senescence in Cancer Cells.

The currently available anti-cancer therapies, such as gamma-radiation and chemotherapeutic agents, induce cell death and cellular senescence not only in cancer cells but also in the adjacent normal tissue. New anti-tumor approaches focus on limiting the side effects on normal cells. In this frame, the potential anti-tumor properties of Pulsed Electromagnetic Fields (PEMFs) through the irradiation of breast cancer epithelial cells (MCF-7 and MDA-MB-231) and normal fibroblasts (FF95) were investigated.

One-step rapid tracking and isolation of senescent cells in cellular systems, tissues, or animal models via GLF16.

Identification and isolation of senescent cells is challenging, rendering their detailed analysis an unmet need. We describe a precise one-step protocol to fluorescently label senescent cells, for flow cytometry and fluorescence microscopy, implementing a fluorophore-conjugated Sudan Black-B analog, GLF16. Also, a micelle-based approach allows identification of senescent cells in vivo and in vitro, enabling live-cell sorting for downstream analyses and live in vivo tracking.

Matrix-based molecular mechanisms, targeting and diagnostics in oral squamous cell carcinoma.

Oral squamous cell carcinoma (OSCC) is a head and neck cancer (HNC) with a high mortality rate. OSCC is developed in the oral cavity and it is triggered by many etiologic factors and can metastasize both regionally and distantly. Recent research advances in OSCC improved our understanding on the molecular mechanisms involved in and the initiation of OSCC metastasis.

The interplay between tumor and nodal microenvironments for the formation of nodal premetastatic niche in head and neck cancer.

Head and neck cancer (HNC) encompasses a number of malignancies originating in the head and neck area. In patients with HNC, cervical lymph nodes constitute metastatic sites for cancer cells that escape primary tumors. The premetastatic niche (PMN) is a crucial concept in understanding metastatic disease.

Impact of Amplified Oncogenes on Salivary Gland Carcinomas.

In normal epithelia, proto-oncogenes regulate critical intra- or intercellular functions, including cell growth and proliferation, apoptosis, and signaling transduction from the cell periphery (extracellular space) to the nucleus mediated by different pathways. Oncogenes are the mutated or amplified forms of the corresponding proto-oncogenes that are crucially involved in cell neoplastic and malignant transformation during carcinogenesis. Salivary gland carcinomas (SGCs) demonstrate a variety of histogenetic types.
