Description:
h1. Predicting Breast Cancer Proliferation Scores with Apache Spark and Apache
SystemML
h3. Overview
The [Tumor Proliferation Assessment Challenge 2016 (TUPAC16) |
http://tupac.tue-image.nl/] is a "Grand Challenge" that was created for the
[2016 Medical Image Computing and Computer Assisted Intervention (MICCAI 2016)
| http://miccai2016.org/en/] conference. In this challenge, the goal is to
develop state-of-the-art algorithms for automatic prediction of tumor
proliferation scores from whole-slide histopathology images of breast tumors.
h3. Background
Breast cancer is the leading cause of cancerous death in women in
less-developed countries, and is the second leading cause of cancerous deaths
in developed countries, accounting for 29% of all cancers in women within the
U.S. \[1]. Survival rates increase as early detection increases, giving
incentive for pathologists and the medical world at large to develop improved
methods for even earlier detection \[2]. There are many forms of breast cancer
including Ductal Carcinoma in Situ (DCIS), Invasive Ductal Carcinoma (IDC),
Tubular Carcinoma of the Breast, Medullary Carcinoma of the Breast, Invasive
Lobular Carcinoma, Inflammatory Breast Cancer and several others \[3]. Within
all of these forms of breast cancer, the rate in which breast cancer cells grow
(proliferation), is a strong indicator of a patient’s prognosis. Although there
are many means of determining the presence of breast cancer, tumor
proliferation speed has been proven to help pathologists determine the
treatment for the patient. The most common technique for determining the
proliferation speed is through mitotic count (mitotic index) estimates, in
which a pathologist counts the dividing cell nuclei in hematoxylin and eosin
(H) stained slide preparations to determine the number of mitotic bodies.
Given this, the pathologist produces a proliferation score of either 1, 2, or
3, ranging from better to worse prognosis \[4]. Unfortunately, this approach is
known to have reproducibility problems due to the variability in counting, as
well as the difficulty in distinguishing between different grades.

h3. Goal & Approach
In an effort to automate the process of classification, this project aims to
develop a large-scale deep learning approach for predicting tumor scores
directly from the pixels of whole-slide histopathology images. Our proposed
approach is based on a recent research paper from Stanford \[1]. Starting with
500 extremely high-resolution tumor slide images with accompanying score
labels, we aim to make use of Apache Spark in a preprocessing step to cut and
filter the images into smaller square samples, generating 4.7 million samples
for a total of ~7TB of data \[2]. We then utilize Apache SystemML on top of
Spark to develop and train a custom, large-scale, deep convolutional neural
network on these samples, making use of the familiar linear algebra syntax and
automatically-distributed execution of SystemML \[3]. Our model takes as input
the pixel values of the individual samples, and is trained to predict the
correct tumor score classification for each one. In addition to distributed
linear algebra, we aim to exploit task-parallelism via parallel for-loops for
hyperparameter optimization, as well as hardware acceleration for faster
training via a GPU-backed runtime. Ultimately, we aim to develop a model that
is sufficiently stronger than existing approaches for the task of breast cancer
tumor proliferation score classification.
