ABSTRACT Successful digital image analysis (DIA) of cancer tissue is accurate and reproducible. These points of emphasis have brought procedures like the tissue microarray (TMA) and hotspot regions of interest (ROI) under scrutiny. The nature in which a pathologist selects TMAs and ROIs is conducive to bias. Whole Slide Imaging (WSI) offers a solution in its unbiased region selection and consideration of a larger tissue sample. However, options for software that can handle such large throughput are scarce. Additionally, while multiplex immunohistochemistry (mIHC) is becoming popular (Feng et al.), documentation of its digital analysis tools remains minimal. The combination of these procedures potentiates a deeper understanding of the tumor microenvironment. This study presents the whole-slide mIHC analysis capabilities of QuPath, an open-source application developed at Queen's University Belfast . Methods. A multiplex fluorescent stain panel was performed on patient samples. The slides were imaged and cells were detected and segmented in QuPath. QuPath parallelizes its workload to manage whole-slide throughput efficiently. Custom scripts were written that exhibit machine-learning and thresholding techniques to aggregate cell phenotype totals. Additionally, cell detection numbers were generated for specific ROIs and compared to a proprietary DIA software. All scripts and protocols in this study are made public for replication and improvement by the community. Results. QuPath's automated cell segmentation and classification were demonstrated as a proof-of-concept for whole-slide multiplex immunohistochemistry analysis. Across an entire slide, cells positive for multiple markers were effectively segmented and properly phenotyped. Conclusion. Open-source applications have become a driving force for innovation and collaboration in the field of digital image analysis. In litigating the strengths and weaknesses of QuPath for whole-slide mIHC analysis we aim to advance the field's knowledge of available software tools and bring attention to necessary points of growth in this rapidly changing industry.

CONCLUSIONS
Preliminary results using QuPath open-source software to analyze whole-slide multiplex IHC suggests that it holds promise as an approach to assess complex fluorescent images.
*COMMENT
This study was undertaken as an undergraduate student summer project and may be a component of a senior thesis project
Hurdles for Technology & Opportunity Multiplex IHC technology provides unprecedented opportunities to investigate tissues. However, there are weaknesses in the way cells are enumerated. In an attempt to standardize and better understand best practices for evaluating T cell populations and expression of activation markers, a T cell Activation Marker Proficiency Panel (TAMPP) has been initiated. Populations of human T cells, extensively characterized by FACS, have been prepared into cell blocks. Slides will be sent out containing sections of the characterized T cells for participating labs to perform multiplex IHC, analyze and return results. Results will be summarized, site ID blinded and data shared, along with FACS phenotypes, with the participating labs. This academic-based collaboration is open to participation by all groups (academic & commercial) using any multiplex technology with results prepared for publication.
