Do flu outbreaks correspond with a higher likelihood of dying for lung most cancers sufferers? It might look like an easy query at first, however when you dig into it, you notice it’s not really easy to reply. However because of a multi-disciplinary venture involving researchers at Columbia Medical College and the large information analytics software program and experience from Virtualitics, the outcome turned out to be each clear and compelling.
Oncologists have lengthy theorized that influenza outbreaks pose a selected risk to lung most cancers sufferers. In spite of everything, flu and flu-like diseases have a tendency to focus on the higher respiratory tract, which is an space of stress for lung most cancers sufferers. Nevertheless, oncologists have lacked empirical proof exhibiting that unhealthy flu outbreaks correspond with an uptick in deaths amongst lung most cancers sufferers. That’s, till now.
Because of a joint analysis venture by researchers on the Columbia Medical College and information scientists working for Virtualtics, oncologists now have a greater grasp of how influenza outbreaks affect lung most cancers sufferers. The research, which was documented in a 2023 paper within the journal Scientific Studies, confirmed that lung most cancers sufferers have a 25% higher likelihood of dying throughout extreme flu outbreaks in comparison with intervals when the unfold of flu is low.
The sturdy outcomes happy Dr. Simon Cheng, the Columbia Medical College oncologist who led the research.

“We had been hoping to give you one thing attention-grabbing, clearly, and that we might make the suitable correlations,” Dr. Cheng informed Datanami. “[But] we didn’t anticipate to see one thing that top. I feel that was very stunning.”
The research was additionally a victory for Virtualitics, the Pasadena, California analytics agency that was spun out of a California Institute of Know-how astronomy information lab. The corporate has discovered success making use of its mix of analytics, machine studying, and visualization instruments with navy and authorities prospects, and this win reveals it has one thing to supply the medical subject too.
“We introduced the software program and the AI experience, and we got here up with an issue that they had been interested by exploring additional,” Virtualitics CEO and co-founder Michael Amori mentioned. “They’d the information associated to it, and so we simply partnered up mentioned, hey let’s see if we are able to discover one thing attention-grabbing which may truly do some good as nicely, and to additionally show that our platform actually could be very highly effective and can be utilized additionally in healthcare.”
Multi-Variate Evaluation
What made this research difficult was that it sought to determine correlations between two information variables–incidence of flu and lung most cancers–in populations over each time and area, Dr. Cheng mentioned.
“Once we do these analyses, it’s onerous to take a look at all of the variables without delay and seeing what stands out, and in order that’s the explanation why we collaborated with Virtualitics,” Dr. Cheng mentioned. “They had been in a position to pinpoint sure issues.”
The non-small cell lung most cancers information got here from the federal government Surveillance, Epidemiology, and Finish Outcomes (SEER) database. When any person is recognized with most cancers, it have to be reported to the registry, mentioned Columbia Medical College oncologist Dr. Connor Kinslow. “There’s various high quality management checks, so typically the standard of the information could be very excessive,” Dr. Kinslow mentioned. “This can be a database that’s actually the gold normal for most cancers information assortment.”

The research used flu information from the Facilities for Illness Management and Prevention. Each week, the CDC collects information on flu and flu-like diseases throughout a community of three,500 suppliers as a part of the U.S. Outpatient Influenza-like Sickness Surveillance Community (ILINet). The incidence of flu was damaged down by severity into low, medium, and excessive ranges.
To correctly examine the 2 datasets, the researchers needed to discover a frequent denominator. Whereas the flu information was offered at a weekly interval on a state-by-state foundation, the SEER information was offered at a ZIP Code granularity, however solely on a month-to-month cadence. Due to this fact, the core unit of measure that the Columbia researchers used was a state-month, Dr. Kinslow mentioned.
Really merging the 2 information units was an entire different challenge. “Using a few of these databases does take a good quantity of coding expertise as a result of the information could also be damaged up throughout many Excel spreadsheets or many alternative recordsdata,” he mentioned. “Simply wrangling all that information and merging it collectively takes a good diploma of talent.”
The researchers had assist from a pc science Grasp’s diploma scholar at Columbia who contributed to the information wrangling effort.
Searching Correlations
As soon as the information was loaded, standardized, and prepped on a big cluster working within the cloud, the Virtualitics information scientists might apply the corporate’s proprietary software program.
“What Virtualitics did was they used a reasonably refined mathematical approach, the place they took…about 10,000 samplings throughout every state-month after which plotted the density and in contrast these statistically,” Dr. Kinslow defined. “Additionally they helped us overcome some form of biases inside the information.”
The Virtualitics software program, which was initially designed at Caltech to investigate astronomical information, incorporates many built-in machine studying algorithms. The software program runs the algorithms in opposition to the information and robotically determines which algorithms are one of the best match for the information. What units Virtualitics other than different merchandise is the way it explains what it’s doing, Amori mentioned.

“Our platform makes use of AI-guided visualizations of advanced information and actually focuses on explainable AI, which means the AI spits out explanations for the sample that it sees within the information,” he mentioned. “That permits you to actually question the information a lot quicker and in an explainable approach, so that you simply actually perceive what the AI is doing.”
Maybe the largest contributions Virtualitics made had been the visualizations, in keeping with the Columbia scientists. The mixture of the Virtualitics software program within the arms of succesful firm information scientists helped ship compelling visualizations that demonstrated the rise in extra mortality amongst lung most cancers sufferers in periods of excessive influenza. The corporate additionally developed a film that confirmed the information over time.
“It’s fairly cool,” Dr. Kinslow mentioned of the film, which might be considered within the supplemental supplies part of the Nature research right here. “It’s a time-lapsed map of the US the place it truly overlays influenza outbreaks with the lung most cancers mortality. And that could be a nice visualization for principally our fundamental outcome which you could visually see the correlation over time and area.”
Constructive Outcomes
The research was a win for the researchers, for Virtualitics, and for most cancers sufferers. Research present that most cancers sufferers are vaccinated in opposition to influenza at about the identical charge as the final grownup inhabitants within the U.S., or about 40%. This research means that the loss of life charge of lung most cancers sufferers throughout flu season might be decreased if extra sufferers acquired a flu shot each fall.
The truth that Virtualitics might contribute its software program and experience within the furtherance of science feels good, Amori mentioned. However AI has much more to contribute, he mentioned.

“I learn that it normally takes about on common 17 years for brand spanking new discoveries in medication to make it into mainstream medication, in order that’s not good,” Amori mentioned. “However you’ve acquired to start out someplace, and I feel the ability of AI is unimaginable. If you know the way to marshal it, for those who’ve acquired the suitable platform, the suitable sources, you could find actually helpful issues that may assist the world.”
Dr. Cheng additionally sees a future for AI in medical analysis. Whereas AI has typically been touted as a savior on this subject, there have been many extra failures than successes. However this victory might assist pave the best way for extra success down the street.
“The best way the platform permits you to make sense of the information and to visualise the information, it actually confirmed us that there’s lots of alternative on the market,” Dr. Cheng mentioned. “In healthcare information and EMR information, there’s lots of data. There’s lots of variables, and it’s very troublesome to make sense of what’s a very powerful factor. The thought of simply making an attempt to throw all of the variables right into a field and one way or the other attempt to visualize it and perhaps see which one is essentially the most impactful, most necessary issue, could be very useful.”
