3rd Digital Pathology Congress Asia-Pacific 2017

At the 3rd Digital Pathology Congress Asia-Pacific 2017, Dr Yu Weimiao (Head, Computational BioImage Analysis (CBA) Unit, Institute of Molecular and Cell Biology, A*STAR) gave a presentation on Quantitative Imaging and Deep Profiling of Collagen Structure for Asian Triple Negative Breast Cancer: Novel perspectives for Breast Cancer Micro-Environment.

Abstract
The ExtraCellular Matrix (ECM) maintains normal tissue polarity and architecture and also prevents cancer cell invasion. Therefore, deregulation and remodeling of the ECM dynamics are one of the prerequisite and hallmarks of cancer. The importance of stromal biology in breast tumor progression is highlighted in many studies.
 
We used a novel imaging solution to explore the collagen structure in TNBC: Second Harmonic Generation (SHG) and Two-Photon Emission (TPE) imaging: The SHG imaging will fully quantify the micro-environment, including collagen type I & III, blood vessel (angiogenesis) and stromal structures.
 
We developed an automatic image analysis solution to extract different features in the SHG images, including collagen structural information, which plays a key role in the aggressiveness of the breast cancer. The extracted parameters are then correlated with our clinical outcome.
 
Several imaging parameters from SHG-TPE technology have shown potential to clinicopathological parameters, such as tumor grade, size, lymph node staging, survival rate, as well as PD-L1/PD-1. Our deep profiling of the 388 patient samples shows novel understanding of the micro-environment change during the breast cancer progress.

Latest Paper of Histoindex's Genesis is published in Scientific Reports

Abstract: Liver fibrosis assessment by biopsy and conventional staining scores is based on histopathological criteria. Variations in sample preparation and the use of semi-quantitative histopathological methods commonly result in discrepancies between medical centers. Thus, minor changes in liver fibrosis might be overlooked in multi-center clinical trials, leading to statistically non-significant data. Here, we developed a computer-assisted, fully automated, staining-free method for hepatitis B-related liver fibrosis assessment. In total, 175 liver biopsies were divided into training (n = 105) and verification (n = 70) cohorts.

Low cost and compact nonlinear (SHG/TPE) laser scanning endoscope for bio-medical application

Abstract: Two-photon fluorescence (TPE) and second harmonic generation (SHG) can be used to extract biological information from tissues at the molecular level, which is blind to traditional microscopes. Through these two image contrast mechanisms, a nonlinear laser scanning endoscope (NLSE) is able to image tissue cells and the extra cellular matrix (ECM) through a special fiber and miniaturized scanner without the requirement of poisonous chemical staining.

Therefore, NLSE reserves high potential for in-vivo pathological study and disease diagnosis. However, the high cost and bulky size of a NLSE system has become one of the major issues preventing this technology from practical clinical operation. In this paper, we report a fiber laser based multi-modality NLSE system with compact size and low cost, ideal for in-vivo applications in clinical environments. The demonstration of the developed NLSE nonlinear imaging capability on different bio-structures in liver, retina and skin are also presented.

Keywords: Second-harmonic generation, Two-photon fluorescence, Ultrafast fiber laser, Endoscopy
