About This Project

Breast cancer is the second most common cause of cancer death among women, and requires careful histologic study for diagnosis. I am studying the feasibility of recognizing breast cancer cells in histologic specimen by means of artificial intelligence. We will train convolutional neural networks to recognize tumour cells in small snippets of large images. If positive, the region in the image corresponding to the snippet is marked. Our preliminary results are promising (see also lab notes)!

What is the context of this research?

Breast cancer is the most common cancer type among women and the second most common cause of cancer death among women. Diagnosis of breast cancer is established using several different methods: physical examination, radiology and histology.

During histologic study, breast tissue is biopsied and examined by a pathologist. This is a critical step in correctly diagnosing cancerous cells and planning necessary treatment.

The human eye is able to recognize a large variety of pathologies, but the procedure can be time consuming and error-prone. Careful examination of histological material is critical to correct diagnosis and treatment of patients.

What is the significance of this project?

During the past decade there has been a rapid evolution of convolutional neural networks (https://en.wikipedia.org/wiki/...). This form of artificial intelligence has been applied to medical imaging and histopathology to identify mass lesions in mammography [5], with promising results.

Automated detection of tumour cells in histologic specimen will help pathologists scan more samples in less time and focus on difficult cases. In some cases thorough histological examinations can take up to one hour.

This technology could decrease the cost associated with breast cancer screening and allow for more thorough screening of biopsied tissue.

Moreover, this project should also provide us with the necessary knowledge to apply our findings to other types of tumours.

What are the goals of the project?

The goal of our project is to provide a faster mean of detection of cancer cells in histologic specimen. We believe that AI can be used to identify cancer cells in histologic specimens with as much accuracy as the human eye.

We will test this by training convolutional neural networks to identify breast cancer cells in images of prepared samples, and comparing the success rate of our CNN to that of humans identifying cancerous tissue. We have created an image database of human breast cancer and normal breast tissue. We have created the necessary programs for the training of the convolutional neural networks (CNNs) and we have set up a database for the results.

Training of Neural Network is done by complex algorithms. They use millions of variables to train the neural network. The process of training is computationally demanding. Although graphic cards are often used for gaming, their internal layout is a very powerful parallel processor with many thousands of compute cores that can perform the necessary calculations faster. Without a graphics card, the necessary calculations might take years instead of weeks. As we are analyzing medical data, we are not permitted to transfer the images to other computers where such graphic cards are already installed. No manpower costs will be covered by this item.

Endorsed by

Dr. Fritze focuses on problems arising in medicine and histopathology and works on developing faster means for detecting cancer cells in histologic specimen. This is a highly relevant area where any progress will have high positive impact. Since he combines profound knowledge in medicine with expertise in computer science, Dr. Fritze is in an excellent position for successfully carrying out such a project. I therefore fully endorse this project and recommend supporting it.
This project is highly relevant as automated segmentation of tumor tissue will save a lot of time in clinical practice. Robert Fritze is the ideal person to carry out this project as he combines excellent medical knowledge with computer science skills. The results of this project will be of interest for my collaboration partner Anke Meyer-Baese (Florida State University) who focuses on the detection of non-mass leasions. I fully support this project and strongly recommend funding.
Increasing the accuracy and the speed of diagnosis using new investigator independent methods is a fast growing and promising field in medicine and histopathology. Automated detection of breast cancer cells using AI methods will help to achieve this goal. I know Dr. Fritze not only as a hard working clinical physician, but also as hard working scientist and profound expert in medical informatics, a promising and rare combination.

Flag iconProject Timeline

Research has begun as of Feb 2017. Until now the necessary computer programs have been developed and an image database for histological specimen has been created (after approval of the competent ethical review committee).

Until summer 2018 the training of the neural networks should be accomplished.

Results should be published in Autumn 2018.

Team Bio

Team:

Our team consists of a pathologist (Dr. Milo Halabi, Hospital Ried/Innkreis, Austria), a professor for informatics (Prof. Wilfried Gansterer, University of Vienna), a specialist for the application of neural networks in medicine (Dr. Roxane Licandro, Technical University of Vienna) and me.

Robert Fritze

Motivation:

I believe Informatics has the potential to make valuable contributions towards my aim of developing medicine to alleviate the patient afflictions. Therefore once finished my studies in medicine I have started to study informatics. During the study program I became aquainted with many new methods and algorithms. My experience in the medical field helps me to identify current problems and find solution strategies. Many of my research ideas are too complex to be worked on by a single person. In this case I try to compile a team of specialists.


Education:

2002 European primary medical qualification, University of Vienna

2012 European specialist medical qualification (anaesthesiology and intensive care medicine)

This project is part of the master’s thesis I am currently writing (in the field of Scientific Computing) at the University of Vienna and I expect to finish the program by Autumn 2018.
