Salivary diagnostics is an emerging field for the encroachment of point of care technology (PoCT). The necessity of the development of point-of-care (PoC) technology, the potential of saliva, identification and validation of biomarkers through salivary diagnostic toolboxes, and a broad overview of emerging technologies is discussed in this review. Furthermore, novel advanced techniques incorporated in devices for the early detection and diagnosis of several oral and systemic diseases in a non-invasive, easily-monitored, less time consuming, and in a personalised way is explicated. The latest technology detection systems and clinical utilities of saliva as a liquid biopsy, electric field-induced release and measurement (EFIRM), biosensors, smartphone technology, microfluidics, paper-based technology, and how their futuristic perspectives can improve salivary diagnostics and reduce hospital stays by replacing it with chairside screening is also highlighted.

Human whole mouth saliva (WMS) is secreted by salivary glands, namely parotid, submandibular/sublingual and other minor glands of the oral cavity. It is secreted in a systematic way, and contain informative proteins and peptides for the early detection of contagious diseases and organ-related diseases. The role of WMS as a liquid biopsy for the detection of cardiovascular diseases (CVD) through Myoglobin (MYO), Cardiac troponin I (cTnI), Creatine phosphokinase MB (CK-MB), Myeloperoxidase (MPO), brain natriuretic peptide (NT-proBNP), Exosomal miRNA, C-Reactive Protein (CRP), Matrix metalloproteinase-8 (MMP-8), MMP-9 and tissue inhibitor of MMP-8 (TIMP-1), leukotriene B4 has been well reported in last decade, that have been reviewed in the literature comprehensively below.

Oral cancer refers to malignancies that have higher morbidity and mortality rates due to the late stage diagnosis and no early detection of a reliable diagnostic marker, while oral squamous cell carcinoma (OSCC) is amongst the world’s top ten most common cancers. Diagnosis of cancer requires highly sensitive and specific diagnostic tools which can support untraceable hidden sites of OSCC, yet to be unleashed, for which plenty of biomarkers are identified; the most recommended biomarker detection medium for OSCC includes biological fluids, such as blood and saliva. Saliva holds a promising future in the search for new clinical biomarkers that are easily accessible, less complex, accurate, and cost effective as well as being a non-invasive technique to follow, by analysing the malignant cells’ molecular pathology obtained from saliva through proteomic, genomic and transcriptomic approaches. However, protein biomarkers provide an immense potential for developing novel marker-based assays for oral cancer, hence this current review offers an overall focus on the discovery of a panel of candidates as salivary protein biomarkers, as well as the proteomic tools used for their identification and their significance in early oral cancer detection.

2508 Background: Dysregulation of the MET pathway can promote tumor growth and metastasis, making MET an attractive target for cancer therapy. AMG 337 is an investigational, oral inhibitor of MET kinase activity. This study evaluated the safety, tolerability, pharmacokinetics, and efficacy of AMG 337. Methods: Key eligibility: age ≥ 18 years, advanced solid tumors, measurable disease, ECOG ≤ 2, adequate organ function. AMG 337 was administered orally QD or BID on D1 and D3–28. After 1 week without AMG 337 in the absence of dose-limiting toxicity (DLT) or progression, pts resumed AMG 337 until progression. The starting dose of AMG 337 was 25 mg with planned dose escalation of 50-500 mg QD and 100-200 mg BID (3-9 pts/cohort) until the maximum tolerated dose (MTD, highest dose at which < 33% of pts/cohort had a DLT) was reached or the highest dose was tested. Pts with MET overexpression/amplification/mutation could enroll to the highest dose deemed safe at any time. Results: As of OCT 2013, 66 pts (QD escala...

3023 Background: PBI-05204 (Oleandrin), a cardiac glycoside, inhibits the α-3 subunit Na-K ATPase pump. Relative expression of the α-3 subunit in tumor cells correlates with proliferation. Oleandrin inhibits FGF-2 export, activation of NF-Kβ, phosphorylation of Akt, p70S6K, decreasing mTOR activity. In this first-in-human study, we sought to determine the MTD/recommended phase II dose and to define the pharmacokinetics (PK) and pharmacodynamics (PD) of PBI-05204 in advanced cancer patients (pts). Methods: Trial was a 3+3 phase I design. PBI-05240 was given for 21 of 28 days. Dose was increased by 100% if no related grade 2 adverse event (AE) emerged and increased by 50% if a grade 2 AE occurred. Blood samples were drawn for PK and drug-mediated changes in pAkt, p70S6K, and S6 (mTOR effectors) expression in peripheral blood mononuclear cells (PBMCs) for PD analysis. Results: 46 pts were dosed at 8 dose levels (DL) of PBI-05204 (0.6 to 10.2 mg/day). 2 dose-limiting toxicities occurred at DL 8 (grade 3 prote...

Objective: To compare mast cell and microvessel densities among histologic grades of oral squamous cell carcinoma. Setting: Armed Forces Institute of Pathology. Materials and Methods: A total of 60 specimens of OSCC comprising 20 each of well, moderately and poorly differentiated were evaluated. Immunohistochemical analysis was performed to measure MCD and MVD by applying monoclonal CD117 antibody and monoclonal CD34 antibody, on formalin fixed and paraffin embedded sections. ANOVA and Post Hoc Tukey test was employed to assess the densities and to compare the differences between different grades of OSCC. A p-value
