Colorectal cancer is one of the leading causes of cancer-related deaths worldwide. It is estimated to be the third most common cancer and the second leading cause of cancer death in both men and women. A development known as a polyp, which may initially be noncancerous (benign) or later turn cancerous, is how colorectal cancer typically manifests.

The everwidening uses of AI in healthcare industry are astonishing. AI can play a significant role in detecting colorectal cancer by assisting in various aspects of the screening and diagnosis process. A few very important examples are:

  • In medical imaging, AI algorithms are capable of finding polyps, lesions, and cancers.
  • Radiologists and pathologists can assess x-rays with the use of AI-powered CAD systems.
  • Using patient data, AI models can evaluate the risk of colorectal cancer.
  • Natural Language Processing (NLP) can be used by AI systems to extract information from medical records and recognize colorectal cancer.

A very effective HyperCRC-NET module from HS Analysis GmbH can quickly identify both malignant and tumor cells that are on the verge of developing into cancer. Without appropriate data for analyses, detection alone is not sufficient. The HSA KIT software offers the chance to extract all the data into an excel sheet and present the results as reports, graphs, and figures.

The HSA KIT includes professional, top-notch annotation capabilities and offers zooming in to the very last pixel in the image. Existing DL models can be trained on by the clients and optimized for their purposes. Additional annotations can be readily added to the fundamental structures that are already present, in order to boost the model’s detection precision. A high-quality deep learning model will be generated as a result of improved training, thanks to the ground truth data (GTDs) that are all recorded in the database from the beginning.

This is a demonstration of zoom-in capabilities in HSA KIT, making precise annotations possible for GTDs

With a huge set of GTDs, a deep learning AI model is established which has the capability to objectively identify structures and ensure consistency and repeatability; while avoiding subjective viewpoints or preconceptions that effect the analysis procedures.

After the model has been trained and the project has been completed, the HSA KIT software provides the information required to understand the results in a sheet format, including the name of the files, the number of objects (structures), the dimension of the analyzed areas in square meters within specific Base ROI (Region of Interest) area.

The results table shows relevant information about the project to which AI model was applied

The results sheet contains, but not limited to the basic information about the structures. In addition to this information, other details like average area, perimeter, minimum and maximum diameter, average diameter etc. can be added based on the specifications of the module.

HE and Ki67 staining

In histopathology, H&E staining is regarded as a fundamental and standard procedure that provides useful information about tissue samples and aids in the diagnosis and comprehension of a wide range of illnesses and ailments.

Hematoxylin is a blue-purple dye that only stains the nucleus of cells. It turns the cell nucleus a dark blue or purple color after attaching to DNA and other acidic components there.

Eosin staining: Eosin is a pink or red dye that stains the cytoplasm and extracellular elements of tissues. It produces a pink or red tint when it attaches to fundamental components like collagen fibers and cytoplasmic proteins.

The separation between various cell types within the tissue sample as well as the viewing of cellular features and tissue architecture are all made possible by the use of hematoxylin and eosin staining.

Whereas, an immunohistochemical staining method called „Ki-67 staining“ is used to identify and quantify the expression of the Ki-67 protein in cells. During different stages of the cell cycle, actively dividing cells express the nuclear protein ki-67, which is linked to cell proliferation. In many different scientific and clinical settings, Ki-67 staining is frequently employed. This is especially true in cancer research, where it is used to evaluate tumor cell proliferation, ascertain the growth fraction of tumors, and help predict prognosis or treatment response.

Ki-67 antigen, which is expressed during the active phases of the cell cycle (G1, S, G2, and mitosis), is detected and mapped out by staining. A faster proliferation rate and enhanced cell division in the tumor are both indicated by elevated Ki-67 expression.

Under a microscope, the Ki-67 staining reveals the presence and localization of Ki-67 protein expression within the tissue sample, allowing for the evaluation of cell proliferation rates and identification of actively dividing cells.

When analyzing histopathological slides, the HSA KIT offers a one-stop solution for detecting colorectal cancer using several stains. Large datasets of annotated histopathology images are used to train the HyperCRC-Net module on patterns and feature specific to colorectal cancer.

HSA KIT offers the possibility to digitally analyse colorectal carcinoma in biopsies with different staining

Pertinent data from the slides, such as cellular morphology, architectural patterns, and Ki-67 expression patterns is collected, to produce precise predictions or classifications. The detection, segmentation, classification, and grading of colorectal cancer are based on histological characteristics, Ki-67 expression, and proliferation indices. Additionally, they offer prognostic data on patient outcomes and therapy options.

Advanced Heatmap tool

HyperCRC-Net was created with the intention of not only detecting colorectal carcinoma but also measuring the size, extent, and perineural invasion of tumors or malignant glands, all of which are clinically significant traits. The use of this approach in a pathology lab for routine clinical use would be extremely beneficial to pathologists. HSA KIT also provides a heatmap tool which gives slide level scores of specifically chosen endpoints. These heatmaps show the likelihoods or probabilities of the endpoints being present at each pixel on the slide.

The use of this technology by professionals to diagnose and treat cancer patients will completely changed the area of oncology. Future approaches for identifying and treating cancer should become progressively more precise and effective as technology develops.

The advanced Heatmap tool in HSA KIT can be used to understand the decisions of already trained Deep Learning Models. Once a DL model is trained and let run on the files with Colorectal biopsies, carcinoma areas can easily be visualised. By activating xAI and heatmap icon, red region shows the pixels that are mostly important for the DL model to build the class Carcinoma. Blue region shows that DL model use these pixels for building the same class, but does not priories them. In that way it becomes easy to understand the decision of deep learning models during the training process as well as after training.

The underlying training data and training procedure, as well as the results from AI models, provide the finest understanding of an AI system. This knowledge needs the capacity to map a trained AI model to the actual dataset used to train it, as well as the ability to closely analyze that data. Paying close attention to the data used to train a model is one of the simplest methods to improve its explainability. Teams must establish where the data to train an algorithm will come from, whether the data contains bias, and what can be done to reduce that bias during the design process. xAI Tool in HSA KIT finds the target area containing signal in a certain location and it is a discriminative localization technique that can give visual explanations for any project without needing architectural modifications or training.

By activating the “Heatmap” icon in HSA KIT and selecting a structure, the results appears for that structure in visual way.

The images below shows the heatmap of Colorectal carcinoma. The warm colors (yellow and red) represent areas with higher intensity detected by the model and blue regions show low priority pixels for the respective class.

Better workflow with HSA KIT

At HS Analysis, we take a comprehensive approach to slide analysis. We don’t just analyze the slides themselves, but we also integrate our solutions within the existing infrastructure. This includes connecting to LIS (Laboratory Information System) and naming the slides in a way that makes them easy to save, search, and use for medical purposes. Our goal is to provide a seamless experience for our clients, allowing them to access and utilize the data they need quickly and efficiently.

Traditional workflow of medical image analysis is rather cumbersome where the medical images obtained from CT Scans, MRIs or X-Rays is pre-processed and analysed by a radiologist who evaluates and interprets the images to prepare a very subjective report based on his own knowledge. This might be followed up with a quality assurance by another radiologist for second opinion.

On the other hand, AI based analyses using HSA KIT would provide:

  • Standardised process with subjective/objective analysis
  • Extraction of relevant features from raw data and create meaningful representations for training AI models
  • Module selection and configuration without excessive coding
  • Easy to learn software: Annotate , Train and Automate
  • Quick and efficient analysis of multiple medical images which cuts down time for diagnosis or treament
  • Automated report generation to boost productivity and help physicians or radiologists in evaluation process
