Can people beat pancreatic cancer? What to know about Alex Trebek's update

Can people beat pancreatic cancer? What to know about Alex Trebek's update Despite Alex Trebek's upbeat update, the overall statistics for surviving pancreatic cancer remain grim.

Often lost in the dishonest hubbub around wellness-trend-of-the-moment CBD—and all the afflictions that the non-intoxicating cannabis compound can supposedly heal—are the legitimate scientific findings about cannabis’ palliative power, without which there would be no disingenuous oversells.

Here’s one: According to the findings of a recently published study, stubborn and deadly pancreatic cancer might be treatable by a compound found in marijuana, but not a cannabinoid—a common plant chemical (phytonutrient), known for giving fruits and veggies their bright colors, which also contributes to the flavor and aroma of different cannabis strains.

There are more common cancers, but few as deadly as this one

There are more common cancers, but few as deadly as this one The pancreatic cancer diagnosis of "Jeopardy!" host Alex Trebek has focused the country's attention on the disease.

Researchers affiliated with the Dana-Farber Cancer Institute in Boston introduced two different types of pancreatic cancer cells, both isolated and introduced in lab mice, to a cannabis-derived drug called FBL-03G.

The intellectual property of a Baltimore-based company called Flavocure Biotech Inc. (and also the subject of a U.S. Patent Office application first filed in 2015), FBL-03G is “a cannabis-based flavonoid pharmaceutical composition” derived from Cannflavin B, a metabolite of the “typical” cannabis sativa plant. Flavonoids are plant chemicals found in nearly all fruits and vegetables; flavonoids give flora their colors and are also associated with health benefits; thus, isolating and patenting a particular flavonoid could be a viable (and profitable) treatment.

NBC News' Tom Brokaw says politics, medical marijuana help distract from cancer: Report

NBC News' Tom Brokaw says politics, medical marijuana help distract from cancer: Report SurvivorNet went to see the long time NBC News journalist to talk about his experience with cancer and how he’s learned to live with it in the years since his diagnosis.

Pancreatic cancer is particularly deadly, with a five-year survival rate of 8%. One reason why is that pancreatic cancer cells adapt to treatment and become resistant.

But when the pancreatic cancer encountered this particular cannabis-derived flavonoid—in concert with radiation—the cancer cells suffered “a major increase” in cell death. That is, the otherwise stubborn cancer cells suddenly were more likely to go away—to be cured—when exposed to both radiation and the flavonoid found in weed.

“The findings demonstrate the potential for this new cannabis derivative in the treatment of both localized and advanced pancreatic cancer,” the study’s authors wrote. “The results justify further studies to optimize therapy outcomes toward clinical translation.”

The findings were published online on July 23 in the journal Frontiers in Oncology.

To isolate FBL-03G, scientists used flash chromatography and then separated FBL-03G from other various flavonoids found in cannabis by how they interacted with other molecules. The flavonoids were delivered “directly” to the tumors via a method called “smart radiotherapy biomaterials,” described by one Harvard Medical School doctor as “tiny drones to fight cancer.”

This year's event honored the women Justices of the U.S. Supreme Court: Associate Justices Ruth Bader Ginsburg, Sonia Sotomayor, and Elena Kagan.

In one specific experiment, mice left untreated died within 20 days; between 30% and 50% of mice treated with both the flavonoid and radiation therapy were still living after 40 days.

“Overall, the data demonstrates significant therapeutic potential for using FBL-03G in the treatment of both local and metastatic disease, significantly increasing survival,” the authors wrote.

The study is significant insofar as it identifies a cannabis compound that is not a cannabinoid that has therapeutic value. THC and CBD are cannabinoids and interact with the human body’s endocannabinoid system, a network of receptors that regulate key functions like mood, appetite and sleep.

That’s relatively well known and is the scientific basis behind the CBD boom (such as it is). But this study highlights something else entirely: Other compounds in cannabis—not having anything to do with the endocannabinoid system—may also have therapeutic value.

The study’s authors call, as most study authors do, for more research. It will require many more studies—including clinical trials involving humans—before the treatment described here can be patented and prescribed to humans with pancreatic cancer. And it’s also not at all clear if merely using cannabis in some way will deliver the same benefits, and if so, how. Juicing? Smoking? Oils? Who knows! But when you do see cannabis hype, remember why: there’s truth there. You just have to work hard to find it, and that work is still ongoing.

Alex Trebek Releases New PSA to Raise Pancreatic Cancer AwarenessFor the PSA, Trebek (who also made headlines this week when he called a fan with autism who wanted to wish him well) partnered with the World Pancreatic Cancer Coalition to announce the upcoming World Pancreatic Cancer Day, which will be Nov. 21. In the PSA, Trebek points out that cancer still only has an abysmal single-digit, five-year survival rate (2-9%) in most countries. He’s joined 80 organizations from 30 countries to raise awareness of the risks and symptoms.
