Can COVID-19 Help Fight Cancer Tumors?
(upbeat music) - Welcome to Quick News. This is Ted. The news was published on Friday, November 15th. Our article discusses a surprising effect of COVID-19 on cancer patients with possible implications for cancer treatment. So how significant do you think these findings are? - Well, it's quite groundbreaking. For instance, doctors noticed some COVID-19 patients saw their tumors shrink or slow down, suggesting the immune system was triggered by the virus and started killing cancer cells. This isn't just a small deal. It could be a game changer in the long run if these initial observations hold true in larger studies. - Hold on, Eric. It's not that simple. These observations were anecdotal. Based on individual cases that need rigorous scientific validation. Before jumping to conclusions, we need more solid data to improve. But initial studies, using human cells and animal models, did find that SARS-CoV-2 affects monocytes in a way that helps fight cancer. Dr. Parrot's research is showing some promising early results. - Sure, but remember Parrot's study is just one of many steps needed before we can draw solid conclusions. The research needs to be broadened significantly. One positive study doesn't mean we'll see the same. - What exactly do monocytes do during COVID-19 according to this study? - Typically, monocytes signal immune cells about foreign invaders. But in some cancer patients, these cells are tricked by tumors. They form an immune wall protecting the tumor from being discovered and attacked by additional immune defenses. - Right, but during COVID-19, SARS-CoV-2 attaches to monocytes, reverting them back to their original role of defending the body against cancer. This could mean a powerful shift in how the immune system-- - Exactly. - They start recruiting natural killer cells, which are the body's main cancer fighters. That's pretty revolutionary if you think about it. - That's an interesting point, but we can't jump the gun. The observation that some cancer-fighting monocytes proliferate during inflammation, though promising, needs far more investigation. We need thorough, peer-reviewed studies before we-- - And what implications does this have for future treatments? - There's potential to develop drugs that mimic this effect. - The parts team found a compound meramil dipeptide, MDP, which reduced tumors by 60% to 70% in mice. If this can be replicated in humans, it could open new doors in cancer treatment. - That's impressive, but mouse models often don't translate directly to humans. Much more research is required to confirm its viability as a treatment. We need to think long-term-- - Let's dive into the historical context. Are there any historical events that mirror this kind of surprising health discovery? - Yes, Ted. Take the instance of the use of penicillin discovered during World War II. It was a game-changer for treating bacterial infections. It revolutionized the medical field almost overnight. - That's a good example, but I'd point to the discovery of radioactivity's potential in treating cancer. Another unanticipated health benefit, the discovery wasn't intended for cancer treatment initially, but it turned out to be highly effective. Both are valid, but penicillin became a treatment quickly while radioactivity's therapeutic uses required decades of development. It wasn't an overnight success. - True, and Baharat's discovery might follow a similar path, requiring years if not decades of research. We have to be patient. - Exactly, and the exaggerated claims without full validation may create false hopes at an early stage. That kind of miscommunication can be detrimental. - Do you think this discovery could parallel these historical examples in its impact? - Potentially, if the research holds up, it could revolutionize cancer treatment, similar to how penicillin transformed infectious disease management. We could see a new era in immunotherapy. - Or it could be more like the initial hype around antifungal treatments in the '70s, which didn't quite pan out as expected initially. There are always-- - Regardless, the potential to manipulate monocytes as a complementary therapy to other cancer treatments is very intriguing. Even if it's not a standalone treatment, it could still improve patient outcomes. - But caution is key. We must focus on validation to avoid misleading patients and the public. It's a delicate process. - Both historical examples highlight the potential and the risks. What's crucial for making this discovery impactful? - Thorough and replicable scientific studies. If findings are consistent across various conditions and tests, it'll hold more weight. We need a strong foundation to move forward. - Also, regulatory approvals, ethical testing, and clear communication with the public about the stages and expectations. Transparency is essential. - And we must continue juxtaposing new COVID cancer research against other therapies, ensuring it's indeed adding value. It can't just be a standalone study. It has to integrate into existing knowledge. - Absolutely. Understanding limitations and continuing with peer-reviewed studies is the key to breakthrough. Only through diligent work can we progress. - Moving forward, what are the possible paths for these findings on COVID-19 and cancer treatment to unfold? Let's start with you, Eric. - The optimistic path. This research could lead to a new class of drugs mimicking COVID-19 effects on monocytes, especially since more multi-peptide showed promising results in animals. There's a lot of hope here. - Optimistic? There are significant hurdles. The first being human trials. Many drugs show promise in animals, but fail in humans. - True, but advancing to human trials means thorough vetting. Regulatory agencies would ensure safety and effectiveness. It's a necessary step. - Yes, however, let's not forget about cost and accessibility. Even if proven effective, pharmaceutical companies need to make it affordable. This can't just be for the elite. - What about the realistic scenario if human trials are successful yet show mixed results? - A mixed scenario might involve it being used as an adjunct therapy, not a standalone cure. It could be paired with existing treatments strengthening the cancer-fighting toolkit. It's better than nothing. - And even that scenario has complexities. What types of cancer would it target? How would it interact with each patient's unique biology? - Well, the approach isn't reliant on T-cells, potentially boosting therapies for resistant types of cancers, making it a versatile option. It's adaptable to various situations. - Let's not overlook the distribution. Would this be widely available or limited to top-tier healthcare facilities? Accessibility is a major concern. - What about on the pessimistic side, Kate? - If trials fail or show harmful side effects, it might be scrapped or indefinitely delayed like several antiviral drugs were. Risks are always part of the equation. - That's possible, but even failed trials contribute valuable data, guiding future research pathways, nothing is wasted in science. - True, such setbacks aren't an end, but a pivot in the journey of scientific inquiry. - Any final thoughts on what we should watch for as this story develops? - Key early phase results from human trials and how they compare with the animal studies. That'll be the first big indicator of success. - Also, transparency in research findings and long-term investments in unbiased independent studies. This should not be rushed at the expense of quality. - Both great points. Thank you, Eric and Kate, for an insightful discussion. That's all the time we have today. Stay tuned for more updates on this fascinating topic.
