Introduction
In the Department of Analytical Pathology the pathobiological and clinicopathological characteristics of the target molecules are analyzed for evaluating their potential significance in applying diagnostic or treatment use in future. Expression of the molecules or genes in human tissues is assessed by morphological techniques, immunohistochemistry, RT-PCR, in situ hybridization, etc., and the results are compared to clinicopathological information. We also try to develop new, more reliable, or more effective analytical methods and tools.
Research activities
Tumor immune microenvironment in pancreatic cancer is studied clinicopathologically and pathobiologically. We studied how to measure tumor-infiltrating immune cells in the small biopsied pancreatic cancer tissues and showed that more reliable results were obtained by qRT-PCR methods but not by immunohistochemistry.
Education
Teaching the analytical techniques to technicians and researchers in several departments of the National Cancer Center (NCC) was performed.
Future prospects
We will respond the requests from the selected project in various types of studies containing basic, preclinical, and clinical studies, and assess the clinicopathological or pathobiological significance of the target molecules. We will develop methods of quantitative analysis to evaluate morphological findings that currently analyzed qualitatively.
