PATHOLOGICAL PROFILE OF NASOPHARYNGEAL CARCINOMA IN ANATOMICAL PATHOLOGY OF DR SOETOMO GENERAL ACADEMIC HOSPITAL DURING 1 JANUARY 2016 – 31 DECEMBER 2018

Abstract Introduction: Nasopharyngeal carcinoma is the most found head and neck cancer, which originated from a nasopharyngeal epithelial cell, and predilection site commonly at rosen muller fossa. S100 protein inflammatory mediators are involved in the regulation of cellular processes including inflammation and malignancy. S100 protein plays a central role in the proliferation, regulation of cell apoptosis and metastasis causing continuing growth of cancer cells through activation of STAT3 by IL-6, NF-κB, ROS. Objective: This study aimed to determine the correlation between S100 protein expression levels to the clinical stage of NPC WHO type III. Method: This research is a cross-sectional analytic study. This study was held in the Anatomical Pathology Department of Hasan Sadikin Hospital from August until October 2015. The study was conducted using 29 pieces of secondary data, medical records and paraffin blocks anatomical pathology of NPC patients were examined S100 protein immunohistochemistry. Result: This study was performed from 29 subjects (18 males and 9 females). There was a strong positive correlation between histoscore S100 protein expression with clinical staging p<0.05. There is a significant correlation between S100 protein expression with the clinical stage of NPC WHO type III using double regression analysis (F=15.676, p=0.000). Conclusion: There were significant correlation S100 protein expression levels to clinical stage nasopharyngeal carcinoma WHO type III.

BACKGROUND: Nasopharyngeal carcinoma (NPC) is a carcinoma originating from the surface epithelium of the nasopharynx with the highest incidence in China and South East Asia. Currently, many researchers are developing tumor microenvironment which can be assessed by tumor-infiltrating lymphochyte, and its association with treatment response in several tumors, including NPC. Foxp3, known as a regulatory T cell (Treg) marker, plays a role in the immunoregulatory environment of tumor cells and can be used as a prognostic factor. The relationship between Foxp3 expression and treatment response is considered as one of the factors affecting the prognosis of NPC. AIM: This study aims to determine the relationship between Foxp3 expression and treatment response in NPC. MATERIALS AND METHODS: A cross-sectional study was done to analyze the association between Foxp3 and treatment response in NPC. This study included 60 samples who were diagnosed with non-keratinizing NPC at the Department of Anatomical Pathology, Faculty of Medicine Universitas Indonesia/Cipto Mangunkusumo Hospital from January 2018 until December 2020. Immunohistochemistry was done to evaluate the expression of Foxp3. Foxp3 expression was evaluated in the intratumoral and peritumoral areas. RESULTS: Among 60 patients, the number of males were more than females (66.7%, 33.3%, respectively) with a ratio of 2:1. There was statistically significant difference between intratumoral and total Foxp3 expression and treatment response (p < 0.05, p = 0.001, respectively); however, no significant differences found between peritumoral Foxp3 expression and treatment response (p = 0.114). CONCLUSION: Foxp3 expression had a statistically significant relationship with response therapy after chemoradiation.

Antigen Reactivity

A number of antigens have been found associated with persistent EBV infections of lymphoblastoid cells. Identification and localization of these antigens were principally by immunofluorescence (IF) techniques using sera from patients with nasopharyngeal carcinoma (NPC), Burkitt lymphoma (BL), and infectious mononucleosis (IM). Our study was mainly with three of the EBV related antigens, a) virus capsid antigen (VCA), b) membrane antigen (MA), and c) early antigens (EA) using immunoperoxidase (IP) techniques with electron microscopy (EM) to elucidate the sites of reactivity with EBV and EBV infected cells.Prior to labeling with horseradish peroxidase (HRP), sera from NPC, IM, and BL cases were characterized for various reactivities by the indirect IF technique. Modifications of the direct IP procedure described by Shabo and the indirect IP procedure of Leduc were made to enhance penetration of the cells and preservation of antigen reactivity.
