New induction chemotherapy using intra-arterial infusion for tongue squamous cell carcinoma to avoid reconstructive surgery: A 6 case reports.

Most tongue squamous cell carcinoma (TSCC) classified as T3 require reconstructive surgery, which inevitably causes problems with oral functions. We propose new induction chemotherapy using intra-arterial infusion for TSCC classified as T3 to avoid reconstructive surgery. This chemotherapy regimen consists of intra-arterial infusion of docetaxel and cisplatin and systemic administration of 5-fluorouracil.

Antiresorptive agent-related osteonecrosis of the jaw risk in cancer patients before bone-modifying agent therapy: A retrospective study of 511 patients.

Introduction: Antiresorptive agent-related osteonecrosis of the jaw (ARONJ) is a serious adverse event associated with therapies for advanced cancer involving bone-modifying agents (BMAs). Although many studies have investigated the risk factors for ARONJ, none have provided sufficient clarifications. We aimed to determine whether there is a correlation between tooth extraction before BMA therapy and the development of ARONJ.

Comparing the Efficacy of a Microperforated Titanium Membrane for Guided Bone Regeneration with an Existing Mesh Retainer in Dog Mandibles.

Acute-type lateral ridge defects (25 mm × 6 mm × 5 mm) were bilaterally created in the mandibles of four dogs (two defects per animal). The defects were reconstructed with particulate autologous bone and covered with a microperforated titanium membrane (Ti-honeycomb membrane, TiHM) or an existing conventional titanium mesh as control. The samples were dissected after 16 weeks postoperatively and processed for radiographic, histologic, and histomorphometric analyses.

Soluble JAM-C Ectodomain Serves as the Niche for Adipose-Derived Stromal/Stem Cells.

Junctional adhesion molecules (JAMs) are expressed in diverse types of stem and progenitor cells, but their physiological significance has yet to be established. Here, we report that JAMs exhibit a novel mode of interaction and biological activity in adipose-derived stromal/stem cells (ADSCs). Among the JAM family members, JAM-B and JAM-C were concentrated along the cell membranes of mouse ADSCs.

Anti-VEGFR therapy is one of the healing inhibitors of antiresorptive-related osteonecrosis of the jaw.

Introduction: Antiresorptive-related osteonecrosis of the jaw (ARONJ) is a rare but serious adverse event associated with bone-modifying agents (BMAs) and affects patients in the terminal stages of cancer. Molecular targeting drugs (MTDs), anti-vascular endothelial growth factor receptor (VEGFR), and anti-epidermal growth factor receptor (EGFR) drugs are essential in various cancer treatments, although MTDs are risk factors for ARONJ. However, the mechanism through which MTDs affect treatment prognosis of ARONJ remains unclear.

A novel technique of arterial blood flow modification in intra-arterial chemoradiotherapy of maxillary sinus squamous cell carcinoma.

Objectives: Intra-arterial chemoradiotherapy via a superficial temporal artery is reportedly a useful organ-preserving treatment for maxillary sinus squamous cell carcinoma. This study aimed to determine whether blood flow modification facilitates sufficient drug delivery to the entire carcinoma via the maxillary artery alone, even for advanced tumors.

Materials And Methods: A retrospective study of 10 patients who were diagnosed with locally advanced carcinoma (4 [40%] at stage T3, 5 [50%] at T4a, and 1 [10%] at T4b) from August 2016 to July 2018, with tumor blood flow from both the maxillary and facial arteries, was conducted.

Evaluation of a Newly Designed Microperforated Titanium Membrane with Beta-Tricalcium Phosphate for Guided Bone Regeneration in Dog Mandibles.

Purpose: This study evaluated the efficacy of newly designed, laser-perforated pure titanium membranes for guided bone regeneration using beta-tricalcium phosphate (β-TCP), and compared them with the existing membrane.

Materials And Methods: Bilateral acute lateral ridge defects were created in the mandibles of 12 dogs (four defects per animal), which were then randomly divided into two groups (six dogs each). The twenty-four bone defects in each group were then further divided into five groups.

Evaluation of a Newly Designed Microperforated Pure Titanium Membrane for Guided Bone Regeneration.

Purpose: This study aimed to evaluate the safety and efficacy of newly designed, laser-perforated pure titanium membranes for guided bone regeneration and to compare them with an existing product, the FRIOS BoneShield (FBS).

Materials And Methods: Acute-type lateral ridge defects were bilaterally created in the mandibles of 13 dogs (two defects per animal). The defects were randomly divided into three groups and were reconstructed with particulate autologous bone (PAB) in combination with three different titanium membranes: (1) F001M0 (prototype without a frame), (2) F001M1 (prototype with a frame), and (3) FBS as a standard membrane.

Liver X receptor reduces proliferation of human oral cancer cells by promoting cholesterol efflux via up-regulation of ABCA1 expression.

Liver X receptors (LXRs) contribute not only to maintain cholesterol homeostasis but also to control cell growth. However, the molecular mechanisms behind the LXR-mediated anti-proliferative effects are largely unknown. Here we show, by immunohistochemistry, that LXRα and LXRβ are differentially distributed in oral stratified squamous epithelia.
