Abstract

Nasopharyngeal carcinoma (NPC) is a malignant disease derived from nasopharyngeal epithelial cells that have a higher tendency for invasion and metastasis to the cervical lymph nodes than other head–neck malignancies. NPC patients with the same stages often show different progressions and prognoses. This suggests that clinical stages are not sufficient to predict progressivity, so biomarkers are required to provide better progression predictions. Some literature shows that the development and progression of NPC is a complex mechanism involving various components of signal paths, it plays a role in regulating the process of proliferation, angiogenesis and apoptosis. One of the most studied is β-catenin protein that is a key component of the canonical Wnt signal pathway. The β-catenin protein is reported to have roles in increasing the proliferative pathway of c-Myc and cyclin D1, increasing the expression of IL-8 proangiogenesis factor, decreasing expression of RASSF1A tumor suppressor and inhibiting apoptosis through the barriers of caspace-9 activity. To determine the association of β-catenin expression and staging in nasopharyngeal carcinoma patients. The research design used was analytic observational research with cross sectional approach. Samples were enrolled using consecutive sampling. The β-catenin expression was examined from the NPC tissue paraffin block with the immunohistochemical cracking technique, using an anti-β-catenin rabbit polyclonal antibody from Boster Biotechnology, California, USA. The β-catenin expression was assessed visually using a binocular light microscope and a scoring method according to the Allred scale index by an Anatomical Pathology consultant. Statistical analysis was performed using Spearman’s test to determine the association between β-catenin expression and staging in NPC patients. The significance level was α = 0.05. The study was conducted from May to December 2015 at Otolaryngology Unit of Dr. Soetomo General Soetomo, Surabaya. There were 40 patients who fulfilled the inclusion criteria. Spearman test results obtained p value = 0.060. The correlation of β-catenin expression with staging in NPC patients was found to be non-significant (p > 0.05). There was no correlation between β-catenin expression and staging in NPC patients.
