MCO  Study Whole Slide Image Dataset

 The MCO CRC study whole slide image collection is a substantial repository comprising 1,500 digitized tissue slides obtained from patients with colorectal cancer. Spanning the period from 1994 to 2010, the Molecular and Cellular Oncology (MCO) Study Group conducted an extensive research effort involving individuals undergoing treatment for colorectal cancer. As part of this study, a systematic collection of tissue samples, along with comprehensive clinical and pathological data, was conducted from over 1,500 individuals who had undergone surgical removal of tumors in their large bowels.

This collection features one representative tissue section from each case, meticulously stained with hematoxylin and Eosin, and subsequently scanned using an x40 objective. The resulting digitized images boast an impressive resolution that closely mirrors what is observable under an optical microscope—exceeding 100,000 dots per inch (dpi). At such a high resolution, each individual image occupies approximately 2 gigabytes of storage space, contributing to a cumulative size of 3 terabytes for the entire collection of 1,500 images within the MCO Whole Slide Image Collection.

To facilitate accessibility and utilization for research and scientific endeavors, the entirety of the MCO slide image collection is currently made available on the SREDH Platform. The dataset's origin can be traced back to the dedicated efforts of the MCO research group at the University of New South Wales (UNSW), spanning from 1993 to 2011. This invaluable resource serves as a cornerstone for researchers and medical professionals seeking to advance the understanding and diagnosis of colorectal cancer through comprehensive pathological insights.
