BACKGROUND: In 1992, Pribaz described the facial artery musculomucosal flap (FAMM), an axial musculomucosal flap based on the facial artery. The FAMM flap, a modification of the nasolabial and buccal mucosal flaps, is widely used in the reconstruction of defects in the oral cavity. Many modifications of this flap have been described in the literature. Here we aimed to explore the use of an arterialized tunnelized FAMM island flap (a-FAMMIF) for the reconstruction tongue defects after tumor resection...

RATIONALE: Lymphomas are the second most common non-epithelial malignant tumors in the oral and maxillofacial region. Non-Hodgkin's lymphoma (NHL) develops at extranodal sites, and cases involving the maxilla account for less than 1% of all NHLs. We describe a case of diffuse large B-cell lymphoma (DLBCL) in the maxilla, and highlight the clinical signs, symptoms, differential diagnosis, and appropriate treatment of DLBCL in the oral cavity and maxillofacial region. PATIENT CONCERNS: A 67-year-old woman was admitted to our surgical department with pain and swelling in her right upper posterior teeth for about six months...

Targeted therapy is commonly used for treating advanced malignant tumors. Compared with cytotoxic drugs, targeted drugs have the characteristics of good curative results, less adverse effects, and convenient oral administration. Hence, they are especially suitable for patients with cancer who are not able to tolerate chemotherapy. Anti-angiogenic therapy can achieve the objective by inhibiting the formation of new blood vessels in tumors. Apatinib is a novel tyrosine kinase inhibitor targeting the intracellular domain of vascular endothelial growth factor receptor-2...

Background: Vocimagene amiretrorepvec (Toca 511) is an investigational gamma-retroviral replicating vector encoding cytosine deaminase that, when used in combination with extended-release 5-fluorocytosine (Toca FC), results preclinically in local production of 5-fluorouracil, depletion of immune-suppressive myeloid cells, and subsequent induction of anti-tumor immunity. Recurrent high grade glioma (rHGG) patients have a high unmet need for effective therapies that produce durable responses lasting more than 6 months...

BACKGROUND: Recently, the genetic alterations associated with tumor progression and impaired host immunity against transformed cells draw increased attention. Here, we characterized the differential gene expression patterns and protein expression in tumor-free lymph node from recurrent and non-recurrent tumors to identify independent prognostic markers for oral squamous cell carcinoma (OSCC). METHODS: A cDNA microarray analysis was performed to identify the differentially expressed genes in regional tumor-free lymph nodes from OSCC patients with and without recurrence...

OBJECTIVES/HYPOTHESIS: Squamous cell carcinoma of the retromolar trigone (RMT SCC) is a relatively uncommon primary site for oral cavity malignancy. However, given its proximity to the mandible and buccal mucosa, RMT SCC typically exhibits early invasion and generally presents at an advanced stage. Large-sample studies are needed to assess the epidemiology and clinical outcomes of this tumor. Our aim was to describe the determinants of survival in patients with RMT SCC. STUDY DESIGN: Retrospective cohort study...

Purpose: We investigated whether PET radiomic features are affected by differences in the scanner, scan protocol, and lesion location using 18 F-FDG PET/CT and PET/MR scans. Results: SUV, TMR, skewness, kurtosis, entropy, and homogeneity strongly correlated between PET/CT and PET/MR images. SUVs were significantly higher on PET/MR0-2 min and PET/MR0-10 min than on PET/CT in gynecological cancer ( p = 0.008 and 0.008, respectively), whereas no significant difference was observed between PET/CT, PET/MR0-2 min , and PET/MR0-10 min images in oral cavity/oropharyngeal cancer...

Traumatized lipomas with degenerative change may demonstrate histopathologic features that mimic atypical lipomatous tumor (ALT). Previously reported series of ALT involving the oral cavity preceded routine use of MDM2 and CDK4 immunohistochemistry. Our aim is to evaluate MDM2 and CDK4 immunohistochemical expression in adipocytic tumors arising in this site, in conjunction with the histiocytic marker PU.1, to determine whether MDM2 and CDK4 impacts classification. 17 cases originally diagnosed as ALT were retrieved and immunohistochemical studies for MDM2, CDK4 and PU...

Metformin, the first drug chosen to be tested in a clinical trial aimed to target the biology of aging per se, has been clinically exploited for decades in the absence of a complete understanding of its therapeutic targets or chemical determinants. We here outline a systematic chemoinformatics approach to computationally predict biomolecular targets of metformin. Using several structure- and ligand-based software tools and reference databases containing 1,300,000 chemical compounds and more than 9,000 binding sites protein cavities, we identified 41 putative metformin targets including several epigenetic modifiers such as the member of the H3K27me3-specific demethylase subfamily, KDM6A/UTX...

Host's physiology is significantly influenced by microbiota colonizing the epithelial surfaces. Complex microbial communities contribute to proper mucosal barrier function, immune response, and prevention of pathogen invasion and have many other crucial functions. The oral cavity and large intestine are distant parts of the digestive tract, both heavily colonized by commensal microbiota. Nevertheless, they feature different proportions of major bacterial and fungal phyla, mostly due to distinct epithelial layers organization and different oxygen levels...

Background: Oral squamous cell carcinoma (OSCC) is the most common cancer of oral cavity. Tumor stage, thickness, lymph node metastasis (LNM), extranodal spread, perineural invasion, tumor differentiation, mutations, human papillomavirus infection, and tumor microenvironment are independent prognostic indicators of OSCC. However, clinically, among all factors, LNM is considered an important prognostic factor in OSCC as it not only determines the stage of disease but also the strongest independent factor which predicts recurrence of disease...

Mast cells (MCs) have been discovered over 130 years ago; their function was almost exclusively linked to allergic affections. At the time being, it is well known that MCs possess a great variety of roles, in both physiologic and pathologic conditions. In the oral tissues, MCs release different pro-inflammatory cytokines and tumor necrosis factor-alpha that promote leukocyte infiltration in various inflammatory states of the oral cavity. These cells play a key role in the inflammatory process and, as a consequence, their number changes in different pathologic conditions of the oral cavity, such as gingivitis and periodontitis...
