OSC, partners developing cancer microscopy, microarray database

Repository first ever to provide 24/7 access to tumor pathology alongside genetic data; comprehensive knowledge of tumors key to developing personalized treatments

Columbus, Ohio – October 31, 2008 – Researchers in Columbus, Ohio, and Los Angeles are collaborating on a groundbreaking effort that, when fully implemented, will allow health care experts around the world to have comprehensive information about a patient’s tumor at their fingertips.

Led by the Research Institute at Nationwide Children’s Hospital, Childrens Hospital Los Angeles and the Ohio Supercomputer Center, the Virtual Microscopy to Microarray project, or VM2M, aims to bridge the worlds of pathology, genetics and medical treatment. These data are necessary to implement “personalized medicine,” the growing approach of tailoring treatment to the individual and delivering the right dose of the right therapy to each patient. To be effective with these targeted and less toxic therapies, specialists require quick access to genetic information about the patient's tumor and the specific cancer type.

“VM2M will pair high quality microscopy scans of tumors with their specific genetic code, or microarray, and make the information available through a secure online data repository,” said Dave Billiter, director, Research Informatics Core, Nationwide’s Center for Childhood Cancer.

Three main components comprise VM2M: high quality digital microscopy scans of tumors, microarrays of the same tumors that detail their specific genetic code, and the new underpinning technology -- software, data storage, and network access – that enables viewing the two simultaneously.

The Center for Childhood Cancer at The Research Institute at Nationwide Children’s Hospital developed custom computer software that allows multiple pathologists to quickly, simultaneously and securely review, via the Internet, digitally formatted, diagnostic-quality microscopy scans of diseased tissue with the corresponding molecular expression data. Virtual microscopy scans are paired with each sample’s genetic code, or microarray, created by Dr. Timothy Triche at Childrens Hospital Los Angeles.

High-resolution images and data from just 100 patients could easily fill the hard drive on a typical PC, and a comparative analysis of that data on a PC could take a day or more. The Ohio Supercomputer Center provided a secure repository and hosted the development platform during the project’s first phase, which allowed the group to prototype the research project’s concept.

“We’re extremely pleased to be involved in this collaborative effort through our Blue Collar Computing program,” said Ashok Krishnamurthy, senior director of research at the Ohio Supercomputer Center. “OSC’s powerful data management and networking resources enabled storing, organizing and retrieving this memory-intensive information.”
The collaborators are now exploring the next phase of development for VM2M, by moving into a production-supported environment.

“Once the virtual microscopy field receives FDA approval, clinicians will be able to utilize the VM2M platform for diagnosis. This will optimize the process of patient diagnosis, review and treatments that are most appropriate for each individual,” Billiter said.
Funding for the Virtual Microscopy to Microarray project was championed by Congresswoman Deborah Pryce and Congressman Ralph Regula and awarded by the U.S. Department of Health and Human Services through the Ohio Board of Regents.


Ranked in the top 12 on U.S. News & World Report’s 2007 list of “America’s Best Children’s Hospitals,” Nationwide Children’s Hospital is one of the nation’s largest pediatric healthcare networks providing wellness, preventive, diagnostic, treatment and rehabilitative care for infants, children, adolescents and adult patients with congenital disease. A medical staff of nearly 900 and a hospital staff of 6,000 provide state-of-the-art pediatric care for more than 700,000 patient visits annually. As home to the Department of Pediatrics of The Ohio State University College of Medicine, Nationwide Children’s Hospital physicians train the next generation of pediatricians and pediatric specialists. The Research Institute at Nationwide Children's Hospital is one of the top 10 National Institutes of Health-funded free-standing pediatric research facilities.
