Oral microbiome plays an important role in oral diseases. Among them, proliferative verrucous leucoplakia (PVL) is uncommon form of progressive multifocal leukoplakia with a worryingly rate malignant transformation. Here, we aimed to characterize the PVL patients and compare it those healthy controls.Oral biopsies from ten five individuals were obtained used their microbial communities. The sequence V3-V4 region 16S rRNA gene was as taxonomic basis estimate analyze composition diversity bacterial populations present samples.Our results show that are significantly different among donors. average number observed operational units (OTUs) higher for donors than PVL, proving loss PVL. Several OTUs found be more abundant either group. enriched patients, potential protumorigenic pathogens like Oribacterium sp. taxon 108, Campylobacter jejuni, uncultured Eubacterium sp., Tannerella, Porphyromonas identified.Oral dysbiosis suffering To best our knowledge, this first study investigating alterations and, due limited participants, additional studies needed. microbiota-based biomarkers may helpful predicting risks development

The aims of this systematic review are to estimate overall transformation OL and assess risk factors associated with published in last 5 years (2015-2020).We performed a bibliographic search PubMed, Scopus, Web Science, Embase, Cochrane databases keywords "oral leukoplakia", cancer", carcinoma" squamous cell carcinoma". Meta-analysis was conducted using random-effects model.Twenty-four studies were selected, that reported total 16,604 patients. Malignant proportion varied between 1.1% 40.8%.

Histopathological grading of epithelial dysplasia remains the principal laboratory method for assessing risk malignant transformation in oral potentially disorders (OPMDs). Current views on molecular pathogenesis and histological interpretation features are described, use systems is discussed. Changes to current 2017 WHO criteria diagnosis proposed with emphasis architectural dysplasia. The predictive values three-grade binary summarised, categories reviewed, including lichenoid verrucous lesions, keratosis unknown significance, HPV-associated dysplasia, differentiated basaloid implications finding an biopsy clinical management discussed from pathologists' viewpoint.

Oral cancer is a growing problem, accounting for 377,713 worldwide new cases per year, and 177,757 deaths annually representing 5-year mortality rate close to 50%, which considerable that has not decreased substantially in the last 40 years. The main cause of this high related diagnosis percentage oral cancers advanced stages (stages III IV) treatment complex, mutilating or disabling, ineffective. essential at late stage delay diagnosis, therefore, achievement objective improving prognosis involves reducing its diagnosis. reasons are complex involve several actors circumstances—patients, health care providers, services. In paper, we present results scoping review systematic reviews on diagnostic with aim better understand, based evidence, discuss depth, fact, identify evidence gaps formulate strategies improvement.

Patients with oral potentially malignant disorders (OPMDs), including leukoplakia and erythroplakia, proliferative verrucous leukoplakia, submucous fibrosis, lichen planus/lichenoid lesions, can be challenging to manage. A small proportion will undergo cancer development determining a patient's risk is key making management decisions. Yet, our understanding of the natural history OPMDs has not been fully elucidated, precision approach based on integration numerous predictive markers validated by prospective studies. Evidence-based health promotion clinicians healthcare systems embraced universally. Medical surgical interventions evaluated rigorous research measuring important endpoints, such as development, mortality, or survival, are difficult expensive run. Most these studies employ non-ideal surrogate endpoints have deep methodologic flaws. Diagnostic criteria for enrolling subjects uniform, patients highest comprise proportions those enrolled. Few explore quality life patient preferences. It time rethink how we patients, across each OPMD, considering infrastructure cost-effectiveness. Global networks well-characterized populations well-designed interventional trials using outcome measures needed.

The role of dysbiosis in the development and progression oral potentially malignant disorders (OPMDs) remains largely unknown. Here, we aim to characterize compare microbiome homogeneous leucoplakia (HL), proliferative verrucous leukoplakia (PVL), squamous cell carcinoma (OSCC), OSCC preceded by PVL (PVL-OSCC). Fifty biopsies from HL (n = 9), 12), 10), PVL-OSCC 8), healthy 11) donors were obtained. sequence V3–V4 region 16S rRNA gene was used analyze composition diversity bacterial populations. In cancer patients, number observed amplicon variants (ASVs) lower Fusobacteriota constituted more than 30% microbiome. patients had a higher abundance Campilobacterota Proteobacteria any other group analyzed.

Despite the profession placing great emphasis on oral potentially malignant disorders (OPMDs) as a gateway for early recognition and consequently better outcomes cancer, death rates lip cavity cancer have remained stagnant three decades. Evidence shows that only small fraction of cancers are in fact preceded by OPMDs, most OPMDs an annual transformation rate less than 1%. As encompass very heterogeneous group conditions, it could be argued patients with mucosal diseases bearing substantial risk warrant close surveillance treatment, these include proliferative leukoplakia, erythroplakia, non-homogeneous well presenting severe dysplasia at biopsy.
