Exosomes are a sub-population of extracellular vesicles. It is released from all types of cells and are observed to be involved in cellular communications. It contains DNA, RNA, proteins and lipids. Tumor-derived exosomes can modify the tumor micro-environment and promote tumor development. Exosomal miRNAs are functionally linked with cancer progression, metastasis, and aggressive tumor phenotypes. In this review, we initially discuss on the fundamental biology of exosomes and then summarize the recent understanding of the exosomal miRNAs in oral cancer with various biological events. Moreover, the dynamic impact of exosomal miRNAs in the oral cancer micro-environment and their multiple parameter alterations can lead to (i) increased uncontrolled cell proliferation, (ii) oral cancer angiogenesis, (iii) oral cancer metastasis, (iv) drug resistance in oral cancer, (v) reprogramming of the immune system in oral cancer, and (vi) clinical significance of exosomal miRNA in oral cancer detection. Exosomes research can pave way to identify early detection tools in future and personalized medicine development for oral cancer. Thus, our review provides an informative biological insight into exosomal miRNAs in oral cancer, which can benefit the researchers working in the corresponding domain.

Background: T cells are involved in every stage of tumor development and significantly influence the tumor microenvironment (TME). Our objective was to assess T-cell marker gene expression profiles, develop a predictive risk model for human papilloma virus (HPV)-negative oral squamous cell carcinoma (OSCC) utilizing these genes, and examine the correlation between the risk score and the immunotherapy response.
Methods: We acquired scRNA-seq data for HPV-negative OSCC from the GEO datasets.

Purpose: Adrenocortical carcinoma (ACC) is a rare, aggressive pediatric malignancy. Advanced ACC requires multimodal treatment, including surgery and systemic chemotherapy including cisplatin, etoposide, doxorubicin, and mitotane. This is associated with significant gastrointestinal toxicity, resulting in many patients being unable to complete scheduled therapy.

Oral squamous cell carcinoma (OSCC) is the most common form of oral cancer, with increasing global incidence and have poor prognosis. Tumour-infiltrating lymphocytes (TILs) are recognized as a key prognostic indicator and play a vital role in OSCC grading. However, current methods for TILs quantification are based on subjective visual assessments, leading to inter-observer variability and inconsistent diagnostic reproducibility.

High-risk (hr)HPV infection causes oropharyngeal squamous cell carcinoma but only in a fraction of hrHPV+ individuals, suggesting that other factors play a role in cancer development. We investigated oral microbiome in cancer-free subjects harboring hrHPV oral infection (n = 33) and matched HPV- controls (n = 30).

Background And Objective: There is an established association between secondary bladder cancers (SBCs) and radiotherapy (RT) for prostate cancer (PC), which remains a significant concern. Our aim was to update the evidence on SBC incidence across different RT modalities and to compare oncological outcomes for patients diagnosed with SBC to those diagnosed with primary bladder cancer (PBC).
Methods: We searched MEDLINE, Scopus, and Web of Science for studies on SBC following PC.
