Just What The Software Ordered: This AI Could Help Finnish Doctors Spot Cancer

 

In 2014, three young men from far-flung parts of the world teamed up in Finland with an audacious plan that could soon help doctors save more lives, not to mention money, and chart a new course for healthcare.

Oguzhan Gencoglu, who hails from Turkey, is an AI and machine-learning whiz currently working on his Ph.D. in computer science, Hung Ta is a Vietnamese math prodigy with a doctorate in biotechnology, and Timo Heikkinen is a Finnish entrepreneur with a software industry background. Together, they launched Top Data Science, an AI startup based in Helsinki thatâEUR ™ s developing software that can make sense of millions of data points, alert doctors to unseen medical patterns, help them diagnose disease and track patients during treatment.

Their âEURœintelligentâEUR code is already analyzing thousands of MRI images and could one day help radiologists at the Helsinki University Central Hospital diagnose prostate cancer. Another set of algorithms is crunching data from the hospitalâEUR ™ s intensive care unit and using it to identify high-risk cases that may soon need urgent medical care, as well as flag patients who are progressing well and who could be released to standard hospital care. âEURœFor humans, itâEUR ™ s simply impossible to make sense of the hundreds of parameters, the constant flow of number and background information, âEUR Gencoglu says. âEURœFor the algorithm, itâEUR ™ s a piece of cake.âEUR.

Ta, then a big-data consultant, listed on his resume achievements such as the prestigious Marie Curie research fellowship, a Ph.D. in data mining and bioinformatics, an interdisciplinary science involving software and biotech, and a silver medal in VietnamâEUR ™ s national math Olympics. âEURœHis credentials were spectacular, âEUR Heikkinen says. He persuaded Ta to drop his job application and start working with him on their own code. What they had in drive and ambition, they lacked in direction.

A U.S. hospital, for example, generates some 50 petabytes of data per year on average, enough to fill 20 million four-drawer filing cabinets with standard pages of text. 97 percent of the information never gets used.
Their timing was good. In 2014, GE Healthcare launched in Helsinki the Health Innovation Village, a startup incubator located in HelsinkiâEUR ™ s âEURœSilicon VallilaâEUR district. The village is complete with an artisanal coffee shop and tattooed baristas keeping the synapses firing for founders and employees of some 30 promising young companies from across Europe.

They are developing such ideas as a smart needle to help doctors analyze meningitis, a line of clothing for premature babies, and tools to mitigate the side effects of cancer therapy. The denizens of the village are taking advantage of HelsinkiâEUR ™ s active startup scene and events like Slush, a huge technology confab that last fall drew 20,000 visitors, 2,600 startups and some 1,500 investors and speakers, including Silicon Valley legend Vinod Khosla and conference-opener Al Gore.
âEURœWe have partnered with Slush since the beginning of the Health Innovation Village in 2014, âEUR says âEURœvillage chiefâEUR Mikko Kauppinen. âEURœItâEUR ™ s a great place for us to find new startups for the village and showcase the current companies to investors and corporate partners from all over the world.âEUR Heikkinen and Ta secured a desk at the GE village in 2014 and got to work.

By then, theyâEUR ™ d recruited Gencoglu to help them develop Top Data ScienceâEUR ™ s first machine-learning algorithms. Through the Village, they also got access to GEâEUR ™ s business network, and they started showing their software to local medical institutions.

Doctors at the Helsinki University Central Hospital were interested in something similar. They wanted to use Top Data ScienceâEUR ™ s software to help them diagnose prostate cancer using magnetic resonance images and minimize biopsies. Ta and Gencoglu started by feeding their algorithm with thousands of MRI images of the prostate and then used corresponding biopsy information and scores from pathologists to analyze the pictures and detect and classify lesions and other biomarkers in them.

They used 80 percent of their images to train the software and kept the remaining 20 percent âEURœhiddenâEUR from the machine-learning algorithm so they could confirm the results. âEURœWe did this randomly many times so we could statistically validate that the algorithm was actually learning, âEUR Gencoglu says. âEURœWe are trying to predict how aggressive and where precisely the cancer is in the prostate from the MRI image, so we doctors donâEUR ™ t need to do invasive biopsies.âEUR.

The solution is still in development, he says. Next, the hospital decided to test the companyâEUR ™ s software further by optimizing its intensive care unit. The doctors asked Top Data Science to perform two predictive tasks: Use data to identify patients who were at high risk of getting sicker, and spot patients who would remain stable for 12 to 24 hours and could be released from the ICU.

Here the Top Data Science team supplied its software with a diet of tens of millions data points from the records of nearly 3,000 patients who had approved the use of their data. The software looked at second-by-second readings such as heart rate, temperature, and blood pressure, as well as laboratory tests and other vital signs and drug and demographic data.
âEURœIn the first instance, we wanted to alert the doctors to possible adverse events in the near future, âEUR Heikkinen says. âEURœThe second goal was very different. We had to be very sure that it was OK to discharge the patient from the ICU.âEUR After several months, the algorithm found that 13 percent of patients could have been released from the ICU sooner. Their results had 95 percent accuracy.

âEURœWe aim to just provide guidance, âEUR Gencoglu cautions. âEURœUltimately itâEUR ™ s the doctor who makes the decision.âEUR Erno Muuranto, managing director and engineering director at GE Healthcare Finland, says that the country is a good place to work on data applications for healthcare because local hospitals embraced digitization early and now have big databases of patient information going back 10 to 15 years.

âEURœMachine learning depends on access to high quality data, and the learning algorithms typically need large amounts of it, âEUR he says. âEURœMany of GEâEUR ™ s analytics solutions are being developed in Finland, because here, in this small Northern country, hierarchy is low and collaboration with companies, universities and healthcare is straight-forward. âEUR.

The company currently is working with GE Digital to move its software to Predix, GEâEUR ™ s app development platform for the Industrial Internet. The team already has traveled to GEâEUR ™ s software headquarters in San Ramon, California, and to its European Digital Foundry in Paris. Heikkinen says that as patient monitoring becomes remote, with wearable devices keeping track of patients around the clock âEUR” something that MuurantoâEUR ™ s team is working on âEUR” the predictive power of his companyâEUR ™ s software will come into full view.
