I'm no expert, and don't know if it applies in this case, but for a cancer I had (lymphoma) I was told that aggressive can often be easier to treat or "cure" (as defined by survival rates, etc.) since it also can often be hit more brutally by the treatments.
Anyway, since many in my family have died from this horrible cancer, its fantastic news to hear of any improvements there.

What does this mean in layman's terms? How will this potentially help me if I get cancer?
epistasis 16 hours ago [-]
Cancer is not one thing, it's a huge zoo of many many many ways that cells start to break the social contract and divide in an uncontrolled manner.
One of the most commonly observed broken mechanisms is mutation in the gene KRAS that turns this on/off growth switch into the permanently on position.
This has been known for decades, of course. And there have been huge amounts of effort to try to develop drugs that target KRAS in cancer, but for decades it's always been thought of as 'undruggable' because of the difficulty of finding any molecules that would affect it.
This new drug, that finally treats KRAS mutated cancers, goes about it in a new way. Instead of trying to gum up the works of a single protein by sticking a small chemical in it, it effectively "glues" the KRAS protein to another protein, CypA, which keeps the switch away from reaching the normal areas where it's "on switch" activity works.
So this new drug means two things: 1) a lot of the most difficult to treat cancers are now far more treatable, and in the next 1-5 years clinical trials will tell us which cancers this particular drug works well for, 2) there's an entire new class of drug activity that everybody is chasing at this very moment, so in 5-25 years we'll likely have a huge number more of these sorts of treatments.
inigyou 8 hours ago [-]
How does it avoid targeting KRAS in healthy cells? Or is this another form of chemotherapy where we're trying our hardest to deliver the right amount of poison that kills the cancer before it kills the rest of you?
epistasis 6 hours ago [-]
It doesn't. Cancerous cells have a much higher dependency on RAS signaling to survive, so it's a drug that kills everything that's replicating via RAS signaling, much like standard chemotherapy kills cells in general that are reproducing more quickly.
However this is just the first version of the drug, it can be combined with other modalities to allow more selective targeting of cancer versus not cancer cells (e.g antibody-drug conjugation). And when used in earlier stage cancers, rather than the advanced cancers in this first clinical trial, there's the possibility of lower dosing that has less strong side effects.
This is just the first attack that has ever broken through to hit a key weakness of some cancers. It's the start of learning, a breakthrough that will launch refinements, enhancements, and a ton of innovation. That sort of innovation is sometimes derided as "me-too" drugs, and not meaningful, but some of the biggest advancements in cancer care have been from taking very hard to tolerate treatments and making them more tolerable and refined and better for patients, allowing longer and more thorough killing of cancer cells. I would expect we will see a lot of that here, as well as work towards combinations with other drugs.

Can you help disambiguate this? Are there treatments now, or are there potential treatments with trials in 1-5 years?
epistasis 16 hours ago [-]
The next 1-5 years will tell us which cancers this new drug will work well on, right now it's only been tried in pancreatic cancer when people have failed their first treatment. The new drug from the article, daroxonrasib, has nine trials i see currently, here:
The first two are the trial that just completed and showed success: people that have pancreatic cancer that failed other treatments, then a "trial" that is meant to give quick access to more people now that it's been shown to work.
Then there's a trial for using it as the first-line treatment for pancreatic cancer, one for lung cancer (NSCLC), and also various combinations with other drugs. I expect we'll see a ton of new trials registered in the coming year. Especially something in combination with colon cancer, because a common drug resistance mechanism in colon cancer is to develop KRAS mutation.
The thing is that we don't really know which cancers it will work well in until we try. And there's limited number of people with cancer that enter clinical trials, and we want to give each person their very best chance at survival, and then there's the massive expense of running the clinical trial itself, so learning happens slowly, one month of survival at a time, or one cancer recurrence at a time, or one death at a time. Patients that take part in clinical trials really are the heroes here. (Especially with the side effects of this new drug, which are horrible. It is a revolutionary drug, but we need to learn how to manage the other things it does as well, and that's going to take time.)

To me personally, putting people into a permanent state of requiring drugs to survive, is not really cure. It's just maximizing income for those selling those drugs. And none of those drugs work exceedingly well; people still die, even if to other disease or frailties. I don't understand this hype in general.

I can understand being frustrated and cynical with the pharmaceutical industry, but I have never worked with a single doctor that approaches patient care with the goal of getting them "hooked" on something for life.
The pharmaceutical companies are not the ones making clinical decisions - in this case, it's a shared medical decision between a patient and their oncologist.
Having seen how horrific pancreatic cancer is, how difficult it is to treat, and the decades of slow research done by academic scientists to get to this point, I am elated that we have a tool to give patients more time with their families even if their cancer can't be "cured" with this particular drug.
This may seem unsatisfying, but it's real, measurable progress. KRAS has been known about since the earliest days of cancer research, so it's a true breakthrough to finally have a drug targeting it.

I think the meaning is that because we can see success with KRAS mutation of pancreatic cancer, we can now begin clinical trials for other cancers that may have KRAS mutation (colorectal, lung) and see if there is success there. If there is success in treating other cancers during clinical trials, it could be fast tracked through FDA to be more generally available and then become part of the national treatment option (ideally in 1-5 years after clinical trials).

Can we end up with a situation like antimicrobial resistance, where cancer itself evolves to resist these new treatments?
epistasis 6 hours ago [-]
Yes, and one of the hallmarks of cancer is a removal of the usual DNA damage checkpoints. Cells have sensors that detect damaged DNA and stop cell division, and once that is gone evolution happens on an extremely accelerated times scale. In lung cancer, for example, we have developed entire series of drugs to go after successive resistance mutations inside the EGFR gene.
When we first started getting good at sequencing the DNA of tumors, I remember initial reports of taking samples across the 3D space of a tumor and finding great spatial heterogeneity in the tumor genomes.
I'm actually most excited for using this drug in combination with colon cancer, where KRAS mutation is a common drug resistance evolution in response to drugs that target the gene EFGR (though cancer researchers may all have their favorites to go after, colon cancer went after my family especially hard).
nicwilson 6 hours ago [-]
Absolutely, this is selective pressure at work on cells with malregulated genetics. Most typically, this is in the form of drug efflux pumps, but you can definitely get more specific resistances.
Ways to avoid specific resistance include multiple treatments simultaneously, since the probability of generating resistance to both is the product of the probability of resistance either.

Except people don’t ask “what if I get bacteria” the way they ask about cancer.

Without this understanding it becomes a quick jump from "we're spending all this money on cancer" to "we've made no progress"
An example of the nuance plays out in the common cancers (like breast and prostrate). These have between 90 and 100% 5 year survival rates. Others (like the one in this article, pancreatic) have very poor survivability.
As you note, it's very unlikely that we'll "cure cancer". But we already "cure" (for some definition of cure) some cancers. Progress is slow, methodical, and incremental. It can feel like a lost cause when viewed from afar, but up close very real progress is being made. And that's an important message to pass along.

Penicillin works against bacteria, in particular gram-positive bacteria; to a lesser extent gram-negative bacteria too (this depends on the cell membrane structure of bacteria; there are other penicillin derivatives that are also more effective on gram-negative bacteria than penicillin is, but by and large the main target will be gram-positive bacteria). It does not work against human cells. If your comparison is about drugs in general, then of course cytotoxic drugs will have an effect; simplest example I can remember off-hand is colchicin. Of course it should work against cancer cells and non-cancer cells, unless there are some mutations where colchicin could no longer bind to, but that seems very very rare, due to the natural target of colchicin involved in cellular division.
inigyou 8 hours ago [-]
It was an analogy. Just like penicillin kills a broad variety of bacteria we also know substances that kill a broad variety of cancer cells. Arsenic, for instance, and shotgun bullets. The problem is they usually select for all cells or all human cells, not cancer cells more specifically.

Penicillin blocks a specific enzyme (transpeptidase).
Cancer cells, by definition, are not a uniform mass. It will depend on the cancer type, which in turn is defined by the properties those cells have. And mutations happen all the time, often more in cancer cells when their repair systems also have mutations, e. g. are less efficient. By that definition alone, there can never be a wonder-cure for all cancer types. At best you can find some proteins more important (p53 for instance) and while more than 50% of cancer cells have some form of mutation in p53, others simply don't. By that definition there will never be a penicillin-equivalent to all cancer types.

I am very skeptical of conspiracy-minded thinking, so I'd much rather assume his and his team's work hasn't reached escape velocity from obscurity. Especially with larger industries, it takes time and significant breakthroughs to become "a household name", so to speak.

They are working on getting in vivo studies going from what I remember - it's going to take a positive result in a trial on real patients to get attention - that's just how medicine works. You have to show it actually improves longevity and/or patient quality of life before anyone has a reason to care.

If anyone finds this thread because they or someone in their life is currently facing down a pancreatic cancer diagnosis I want you to know that we had significant success with our loved one by focusing, on our end, on diet.
The patient's metastasis markers were so high the value was literally off of the maximum value on the graph on the chart they gave us in the literature, and so, well beyond the level of being surgery eligible.
Over the 12 chemo cycles that number dropped to levels that cancer free people have, and they have gone on to outlive almost every statistic and remain cancer free to this day.
When researching pancreatic cancer following their diagnosis one thing that stood out to me is how the majority of scientific knowledge surrounding cancer addresses the cancer's metabolism. Pancreatic cancer is an IGF-1 (Insulin Growth Factor) metabolic cancer. This can be interpreted as the cancer uses sugar as its fuel source to grow, and in the absence of sugar can alter its internal metabolism to use an amino acid called glutamine as fuel instead. Glutamine is an amino acid found in animal products such as meat and dairy.
With this knowledge we went with a food regiment of removing ALL sugar, and animal products.
The results were significant. Even in their 70s they were able to do the full 12 cycle chemo treatment without needing to delay a single cycle due to negative health markers, and without any major side effects (except fatigue).
The tumor shrunk form 4.2 cm to 2 cm after 6 chemo treatments, and finally shrunk to 1 cm following their final treatment before surgery. (Compare this to studies on tumor shrinkage for the same cancer and chemo treatment, such as: https://www.healio.com/news/gastroenterology/20210722/early-... )
It is my opinion that at this time medical treatment is essential, both chemo and surgical intervention, but if you want something that you can do to try to increase the efficacy of those treatments I highly recommend this nutritional vector as well!
Best wishes for you and your loved ones.

Unfortunately, anecdotes are not data, and although a patient can try anything they want, there is no way to know that such dietary changes are beneficial or potentially harmful for most patients without doing a randomized controlled trial and hoping for strong adherence from the participants.

> anecdotes are not data
It's 2026, this is SOP.
It's why I referenced the metabolic pathways derived from data backed research, linked to a data driven study, and used language like "we had significant success with our loved one" and "if you want something that you can do to try".
Honestly this reads like an "aHCkTualLy!1!" from someone without experience of having a loved one suffering from a cancer diagnosis.
Perhaps you've yet to realize but shallow skepticism against every idea is also distinct from data.
I appreciated your comment, and strongly believe that diet and lifestyle changes are badly ignored when it comes to treating all kinds of diseases, in large part because of the difficulty of getting people to follow through. To be fair, if you're a dementia or cancer patient, making intense lifestyle changes is much harder than pills or surgery.
Anyway, my point is, don't worry too much about the ignorant "but actually" replies here. There's probably been thousands of people who've read your comments and only two felt the need to make these retorts. The others most likely in the majority felt your comment had merit.

This is very true. It was certainly a lot of work for us, and a lot of work for them.
In the first months I was cooking everything.
By the end of the chemo treatment the patient had learned to cook these new meals for themselves.

I have had a family member die of pancreatic cancer before age 60. It is, of course, terrible beyond belief. I'm not sure what you mean by "SOP" in this context. Referencing a bio-plausible mechanism is not actually clinically meaningful. It can provide a direction for study, but does not replace an actual clinical trial. As I said, "a patient can try anything they want".
But since we don't actually know whether such a recommendation will harm or help any individual patient, no one should be taking this recommendation as advice, and at the very least you should not be "highly recommending" specific dietary changes to people based on one anecdotal experience.

I dug a lot into "starving cancer" while we tried to save our dog from an aggressive sarcoma. I can't find his name off hand but I recall reading about a researcher who used a ketogenic diet to keep glucose low, and then occasionally gave drugs to "hammer" the cancer by quickly and temporarily depleting glutamine as well.

Isn’t glutamine also part of vegan diets? I don’t eat meat myself, but your assertion has me wondering about glutamine.
pancreaticdiet 12 hours ago [-]
Yes, and your body requires it for things like muscle maintenance.
Also, sugar is essential to what makes you you, that is, the brain requires glucose to function.
The goal is to reduce excess intake of these things to reduce their availability for any cancer cells to use to grow and divide.
manmal 2 hours ago [-]
Sure, and the body makes its own glucose. The only way to deplete that is prolonged fasting.
If you‘re specifically aiming for low glutamine, going vegan won’t cut it though, depending on what foods you leave in. Soy is high in it. Eg a glass of milk is lower glutamine than a serving of tofu.

Thanks for posting useful link !

That said, I'll happily take "we discovered a key weakness in 20% of cancers," please and thank you.
Anyway, since many in my family have died from this horrible cancer, its fantastic news to hear of any improvements there.
One of the most commonly observed broken mechanisms is mutation in the gene KRAS that turns this on/off growth switch into the permanently on position.
This has been known for decades, of course. And there have been huge amounts of effort to try to develop drugs that target KRAS in cancer, but for decades it's always been thought of as 'undruggable' because of the difficulty of finding any molecules that would affect it.
This new drug, that finally treats KRAS mutated cancers, goes about it in a new way. Instead of trying to gum up the works of a single protein by sticking a small chemical in it, it effectively "glues" the KRAS protein to another protein, CypA, which keeps the switch away from reaching the normal areas where it's "on switch" activity works.
So this new drug means two things: 1) a lot of the most difficult to treat cancers are now far more treatable, and in the next 1-5 years clinical trials will tell us which cancers this particular drug works well for, 2) there's an entire new class of drug activity that everybody is chasing at this very moment, so in 5-25 years we'll likely have a huge number more of these sorts of treatments.
However this is just the first version of the drug, it can be combined with other modalities to allow more selective targeting of cancer versus not cancer cells (e.g antibody-drug conjugation). And when used in earlier stage cancers, rather than the advanced cancers in this first clinical trial, there's the possibility of lower dosing that has less strong side effects.
This is just the first attack that has ever broken through to hit a key weakness of some cancers. It's the start of learning, a breakthrough that will launch refinements, enhancements, and a ton of innovation. That sort of innovation is sometimes derided as "me-too" drugs, and not meaningful, but some of the biggest advancements in cancer care have been from taking very hard to tolerate treatments and making them more tolerable and refined and better for patients, allowing longer and more thorough killing of cancer cells. I would expect we will see a lot of that here, as well as work towards combinations with other drugs.
Can you help disambiguate this? Are there treatments now, or are there potential treatments with trials in 1-5 years?
https://clinicaltrials.gov/search?intr=daraxonrasib&viewType...
The first two are the trial that just completed and showed success: people that have pancreatic cancer that failed other treatments, then a "trial" that is meant to give quick access to more people now that it's been shown to work.
Then there's a trial for using it as the first-line treatment for pancreatic cancer, one for lung cancer (NSCLC), and also various combinations with other drugs. I expect we'll see a ton of new trials registered in the coming year. Especially something in combination with colon cancer, because a common drug resistance mechanism in colon cancer is to develop KRAS mutation.
The thing is that we don't really know which cancers it will work well in until we try. And there's limited number of people with cancer that enter clinical trials, and we want to give each person their very best chance at survival, and then there's the massive expense of running the clinical trial itself, so learning happens slowly, one month of survival at a time, or one cancer recurrence at a time, or one death at a time. Patients that take part in clinical trials really are the heroes here. (Especially with the side effects of this new drug, which are horrible. It is a revolutionary drug, but we need to learn how to manage the other things it does as well, and that's going to take time.)
> Patients that take part in clinical trials really are the heroes here.
Are they?
To me personally, putting people into a permanent state of requiring drugs to survive, is not really cure. It's just maximizing income for those selling those drugs. And none of those drugs work exceedingly well; people still die, even if to other disease or frailties. I don't understand this hype in general.
The pharmaceutical companies are not the ones making clinical decisions - in this case, it's a shared medical decision between a patient and their oncologist.
Having seen how horrific pancreatic cancer is, how difficult it is to treat, and the decades of slow research done by academic scientists to get to this point, I am elated that we have a tool to give patients more time with their families even if their cancer can't be "cured" with this particular drug.
This may seem unsatisfying, but it's real, measurable progress. KRAS has been known about since the earliest days of cancer research, so it's a true breakthrough to finally have a drug targeting it.
Today, only 4 years later, there are two therapies, one RNA based and one CART that would have been usable in her situation. She’d be alive today most likely.
Frankly, you have no idea what you’re talking about as you spew toxic bullshit. 5 year survival would meant being there for her son through high school. That survival rate was 65% in 2022 and closer to 80% now in recent trials.
Normally I’d scroll on, but in these degenerate days it is important to counter bullshit before it becomes policy.
https://usafacts.org/articles/how-have-cancer-rates-changed-...
>However, even though the overall number of cases rises as the population grows, fewer people are getting and dying from cancer. Between 2000 and 2021, the incidence rate — or the rate of new cancer cases per 100,000 people — declined by 5.7%, while the annual mortality rate fell by 27.5%.
Cancer is a broad term encompassing many sorts of malfunction and nearly 40% of Americans will be diagnosed with it at some point because if you survive other hazards and maladies cancer is often what gets you.
If I pulled one person out of a burning building it would be newsworthy. Doctors are and have been pulling train loads every day.
> But that's not a cure. If they don't take that drug, assuming it works, they still have the original mutation in the cancer cells.
The person you're replying to called this out specifically:
> and also various combinations with other drugs.
Why do you think they try it in combination with other drugs? You might be right that this drug alone might not be a cure, but if it inhibits cancer growth, then it empowers other drugs to work more effectively.
> people still die
So what... We do nothing, then? This is your complaint? That we can't be immortal, so why bother trying to cure anything?
I don't understand your type in general.
When we first started getting good at sequencing the DNA of tumors, I remember initial reports of taking samples across the 3D space of a tumor and finding great spatial heterogeneity in the tumor genomes.
I'm actually most excited for using this drug in combination with colon cancer, where KRAS mutation is a common drug resistance evolution in response to drugs that target the gene EFGR (though cancer researchers may all have their favorites to go after, colon cancer went after my family especially hard).
Ways to avoid specific resistance include multiple treatments simultaneously, since the probability of generating resistance to both is the product of the probability of resistance either.
https://www.nature.com/articles/s41586-019-1907-7
sometimes a cancer can then survive on its own back as a single celled organism
We'll just use you!
This is a horrifying proposal not only on the ethics front but also in the scientific uselessness of it.
This is exactly the type of thing that gave the Nazis the bad name they deserve.
Even just subconsciously that would have an effect
I agree: the trials are not speedy enough. None of us will live long enough to take advantage of the endgame version of this.
Also the problem is not only judges, but the scope of detective work being done and when the crime was discovered etc. Judging comes last, but I guess we could deploy the infallible robot police squad which will do a flawless crime scene analysis etc.
I know this is a popular "well actually" to do, but it is not always useful in a conversation. Yes, all cancers are different, but yes, cancer is also one thing: unchecked, harmful division of cells.
Bacteria are also all different, but still they are "one thing", and despite their diversity, antibiotics exist that can deal with many species of them at once. It is reasonable to talk about bacteria and antibacterial medications, it is also reasonable to talk about cancer and cancer treatment. I truly hope cancer will meet its "penicillin" one day (yes I know this is unlikely).
> Bacteria are also all different, but still they are "one thing", and despite their diversity, antibiotics exist that can deal with many species of them at once.
Except people don’t ask “what if I get bacteria” the way they ask about cancer. If the story was about a new antibiotic that only affected 20% of common infectious bacteria strains and someone asked “in laypersons terms, how will this help me if I get a bacterial infection”, it would be appropriate to clarify that it only applies to some bacteria.
Yeah, but doctors also don't tell people "you have bacteria" or claim "we found a cure for bacteria". The lack of nuance on average is largely due to a lack of nuance from experts. The media treats cancer as one big thing and bacteria and viruses as separate things. Thus the average joe inherits 'treating cancer as one big thing' from the media.
But yeah, oncologists aren’t telling people “you have cancer” the way they might say “you have MRSA”.
Honestly, I think people probably get false impressions because cancer usually hits old people and old people are, frankly, often not reliable narrators.
Without this understanding it becomes a quick jump from "we're spending all this money on cancer" to "we've made no progress"
An example of the nuance plays out in the common cancers (like breast and prostrate). These have between 90 and 100% 5 year survival rates. Others (like the one in this article, pancreatic) have very poor survivability.
As you note, it's very unlikely that we'll "cure cancer". But we already "cure" (for some definition of cure) some cancers. Progress is slow, methodical, and incremental. It can feel like a lost cause when viewed from afar, but up close very real progress is being made. And that's an important message to pass along.
Like you said, for a lot of common cancers we have multiple treatments. It's usually not just one magic drug, but rather the doctors working with the most effective treatments down to the least effective treatments.
Now, "no, i mean poisons that attack the special chemistry of cancer," oh yes, those we call chemo.
Penicillin works against bacteria, in particular gram-positive bacteria; to a lesser extent gram-negative bacteria too (this depends on the cell membrane structure of bacteria; there are other penicillin derivatives that are also more effective on gram-negative bacteria than penicillin is, but by and large the main target will be gram-positive bacteria). It does not work against human cells. If your comparison is about drugs in general, then of course cytotoxic drugs will have an effect; simplest example I can remember off-hand is colchicin. Of course it should work against cancer cells and non-cancer cells, unless there are some mutations where colchicin could no longer bind to, but that seems very very rare, due to the natural target of colchicin involved in cellular division.
Penicillin blocks a specific enzyme (transpeptidase).
https://en.wikipedia.org/wiki/Penicillin-binding_proteins
Cancer cells, by definition, are not a uniform mass. It will depend on the cancer type, which in turn is defined by the properties those cells have. And mutations happen all the time, often more in cancer cells when their repair systems also have mutations, e. g. are less efficient. By that definition alone, there can never be a wonder-cure for all cancer types. At best you can find some proteins more important (p53 for instance) and while more than 50% of cancer cells have some form of mutation in p53, others simply don't. By that definition there will never be a penicillin-equivalent to all cancer types.
It most likely will help if you get pancreatic cancer. It might help if you get one of the other types of cancers with this mutation.
And it will likely lead to new treatments for some of the worst kinds of cancer.
The bigger deal about this is that KRAS was considered an "undruggable" target.
Recent advancements have allowed us to design biologics to do things we previously thought impossible, which broadens the horizons for other treatments in the future.
Baby steps.

2. NIH funding notice of awards has slowed to a crawl since Trump did not get his wish to cut Science funding.
3. Putting scientific funding under political control, instructing them to ignore the reviews conducted by peer scientists.
4. Have practically made international collaborations on grants impossible. An expert in Canada or Europe that would be great? Pretty much, too bad.
5. Pushing policies that make grants cancelable at any moment without need to have a justified reason, including potentially for exercising free speech, disagreeing with Administration doctrine, etc, or because you're ugly. This and the funding uncertainty makes planning difficult...just like business, stability/predictability matters.
6. Pushing policies that prevent funds to help cover costs of dissemination, including conference costs.

How do you think new appointees and hires in the NIH/HHS are selected? Political loyalty seems to be a better predictor than scientific impact or output.
> Also not interested in funding anything not research related, including various “offices” that have nothing to do with supporting research. Lots of things to like about these cuts.
The cuts and changes are dramatically impacting research support. Grant money is not being disbursed at the same rate since the new review changes began. You can more plainly characterize the changes as harmful to research in general than focused on removing whatever specific things you don't like.
Prove it. Prove this happens at a large scale. This is just nonsense talking points.
