Immunohistochemistry Profile of Neuroendocrine Tumor of Five Years’ Experience at Tertiary Referral Hospital in Palembang

Abstract

Background

Neuroendocrine tumors (NET) are a type of uncommon neoplasms originating from the neuroendocrine cell system. Recent decades, the prevalence of NET gradually increases, attributing partially to the utilization of advanced detection procedures using modern methodologies.

Objective

The aim of this research was to assess the profile of neuroendocrine tumors of 5 years experiences in our hospital.

Methods

In this retrospective cross-sectional study, a thorough examination was performed on a total of 71 cases obtained from archives of the Department of Anatomic Pathology Mohammad Hoesin Hospital, over the period from 2017 to 2021. The Chi-square test was used for data analysis. Bivariate analysis was performed using binary logistic regression tests to investigate the correlation between the independent variables, including gender and tumor site, and the dependent variables.

Result and Discussion

Out of the 71 recorded samples, 69 samples were subjected to be analyzed while the remaining samples were excluded due to have incomplete data. Four different antibodies were evaluated to find the association between these antibodies and tumor with location (chromogranin, P=0.792; synaptophysin, P=0.100; Ki-67, P=0.026; CD56, P=0.511) and gender (chromogranin, P=0.627; synaptophysin, P=0.929; Ki-67, P=0.315; CD56, P=0.524). Conclusion: The study showed synaptophysin has the highest positive rate on NET diagnosis. There is no association was found between chromogranin, synaptophysin, and CD56 staining to tumor location, except for Ki-67. Similarly, no association was found between staining performance (chromogranin, synaptophysin, Ki-67, CD56) with gender.
