Abstract: 8.30 Identifying The Border Of Cutaneous Squamous Cell Carcinoma By Targeted Egfr Antibodies Conjugated To Gold Nanoparticles

چکیده
INtroductIoN: Treatment goal in cutaneous squamous cell carcinoma (SCC) is complete removal of the tumor with clear histological margins. Gold nanoparticles (GNPs) can be distributed to a tumor by conjugating them with an antibody specific to the tumor’s surface receptor. The consequent change in the optical properties of the cancerous tissue distinguishes it from normal tissue. Given that about 90% of SCCs overexpress epithelium-derived growth factor (EGFR), we sought to determine the sensitivity of diffusion reflection spectroscopy measurements of SCC targeted by GNPs bio-conjugated to anti-EGFR antibodies in identifying residual tumor in excision borders.

متن کاملInfrared-Transparent Gold Nanoparticles Converted by Tumors to Infrared Absorbers Cure Tumors in Mice by Photothermal Therapy
Gold nanoparticles (AuNPs) absorb light and can be used to heat and ablate tumors. The "tissue window" at ∼ 800 nm (near infrared, NIR) is optimal for best tissue penetration of light. Previously, large, 50-150 nm, gold nanoshells and nanorods that absorb well in the NIR have been used. Small AuNPs that may penetrate tumors better unfortunately barely absorb at 800 nm. We show that small AuNPs ...
متن کاملEarly diagnosis of oral cancer based on the surface plasmon resonance of gold nanoparticles
The high mortality rate in cancer such as oral squamous cell carcinoma is commonly attributed to the difficulties in detecting the disease at an early treatable stage. In this study, we exploited the ability of gold nanoparticles to undergo coupled surface plasmon resonance and set up strong electric fields when closely-spaced to improve the molecular contrast signal in reflectance-based imagin...

Abstract Background: Squamous cell carcinoma (SCC) constitutes the main oral malignancy . Parallel to better understanding of molecular and genetic patterns of tumor behavior, more precise correlation of tumor markers such as Epidermal Growth Factor (EGF) and Laminin-5 are sought to estimate macroscopic and microscopic tumor status . Methods: We conducted a cross-sectional study collect...

Background and Aim: This study aimed to indicate the role of epidermal growth factor (EGF) in proliferation and growth of epithelial tissue and to determine the correlation be-tween the frequency of expression of EGF receptor (EGFR) by means of immunohistochemistry with survival rate in oral squamous cell carcinoma (OSCC). Materials and Methods: Thirty-eight cases of OSCC diagnosed by hemato...
