I know a lot of people here are tired of these teaser headlines and don't want to be told anything until there's an actual cure. But here me out - I'm old enough to have lost several friends and family to cancer. Along the way there have always been headlines like this where it seems that a breakthrough is imminent, and you know what? We are much better at preventing, detecting, and treating cancer than we were 40 years ago!

I personally know several people who have gotten breast cancer and survived! I remember when that was practically a death sentence. Ditto for colon cancer. Even your prospects for lung cancer have improved dramatically.

What has made this progress possible is this relentless research. Research that leads to reports being published. Promising leads being discussed. A huge portion of this research leads to dead ends - BUT - some leads to real progress and has in turn lead to real lives being saved. So I say continue with the research and continue publishing and sharing the research results.

    Yes that's true, but I think a lot of the knee-jerk reaction isn't intended to communicate "Stop researching cancer" it's more intended to communicate "Stop linkbaiting us."

    If the title said "Might someday" then that would probably be a more accurate picture of where something at this stage of research is at.

    Obviously some people here want to know all up-and-coming possibilities, clinical trials, or longshots because we're nerds about it. But others of us only care about the ones that are already succeeding in people. Having titles differentiate the two can avoid the frustration.

      Ok but after the first 1500 articles you’ve read about cancer breakthroughs, you understand that you’re going to read about a very early phase research project. You’re no longer sucked in by the baity headlines, are you? Do you really click it and then be totally surprised it says “in mice” in the text?

      • zug_zug 17 hours ago

        So it sounds like you're arguing linkbait is fine because we all have internalized some general skepticism to fight it. But actually I don't think that's the best approach. For one it takes more cognitive overhead to scan through 40 links and then play the mental "what will I actually get if I click this link?" 40 times.

        For the most part HN is great about not having linkbait. But when I do see something that sounds improbably good I just go straight to the comments and see if other people find the article legit (as is the case here).

    • lonelyasacloud 7 hours ago

      On HN one of the things I enjoy and want more of is early news on medical breakthrough; which by its nature is unlikely to be "in humans". So from my pov if it is "in humans" then please put that in the title, otherwise leaving it out "out in animal model x" is just fine and is taken as a given.

      We need more research into immunization against clickbait titling.

  • phtrivier 19 hours ago

    Of course, and I'm glad for you and loved ones (and so sorry for your losses)

    That being said, would any of this incremental research have been slower, or canceled, or derailed, if the HN articles about intermediate reports of lab experiment on mice had the word "on mice" in the title ?

    That's literally all I'm asking for here.

Basically, seed tumors with IFN-1 using targeted RNA nanomolecules (that accumulated in the lungs in this case where they modeled lung cancers). This converts the tumor microenvironment from one hostile to immune cells to one where immune cells are now active and on the hunt for tumor specific neoantigens.

The one open question I wish they would get at is the exact sentization mechanism behind the PD-L1 inhibitor and IFN-1 response. The idea is that cancer cells have selective pressure to hide from the immune system and one way of doing that is presenting this PD-1 receptor to the PD-L1 ligand on the immune cell, an interaction that keeps the cancer cell from being killed and one that PD-L1 inhibitor drugs target to enable tumor cells to now be visible to the immune system (as they output a lot of screwed up things that are otherwise visible to the immune system as "not self").

They tested tumors that aren't sensitive to pd-l1 inhibition so presumably evading immune surveillance another way instead of presenting PD-1, and then found them to then be sensitive to PD-L1.

It could be that within a tumor there are subclonal cells that do express PD-1 but are otherwise protected from PD-L1 inhibitiion having any effect from the hostile tumor microenvironment keeping immune surveillance from operating normally anyhow. Induce the immune response, now the T cell is in the area for PD-L1 inhibition to work. Another possibility is that the IFN-1 induction leads to PD-1 now being expressed by cells that didn't do it previously.

Authors didn't explore this though. Probably would take more experiments and mice are expensive and time consuming. It could be answered by single cell RNA sequencing of these unresponsive tumors and seeing if there is some subset of cryptic tumor cells that do express PD-1 already before IFN-1 induction. As well as measuring expression after IFN-1 induction (maybe several timepoints to measure change in gene expression profile in the tumor population, if any)

This seems so cool that I was immediately suspicious, but this isn't my area of expertise, so it's hard for me to understand the original paper:

https://www.nature.com/articles/s41551-025-01380-1

This is the abstract, though, which suggests the need for a standard "in mice" disclaimer:

> The success of cancer immunotherapies is predicated on the targeting of highly expressed neoepitopes, which preferentially favours malignancies with high mutational burden. Here we show that early responses by type-I interferons mediate the success of immune checkpoint inhibitors as well as epitope spreading in poorly immunogenic tumours and that these interferon responses can be enhanced via systemic administration of lipid particles loaded with RNA coding for tumour-unspecific antigens. In mice, the immune responses of tumours sensitive to checkpoint inhibitors were transferable to resistant tumours and resulted in heightened immunity with antigenic spreading that protected the animals from tumour rechallenge. Our findings show that the resistance of tumours to immunotherapy is dictated by the absence of a damage response, which can be restored by boosting early type-I interferon responses to enable epitope spreading and self-amplifying responses in treatment-refractory tumours.

    The linked article said the vaccine was still in pre-clinical trials, which means it hasn't been tested on humans yet. Mouse models are a stepping stone toward that. When you hear 'pre-clinical' think 'alpha testing', or 'proof of concept' stage.

    The submitted article mentions that it was a study conducted on mice though?

      It's common for medical articles posted here to have a great-sounding breakthrough in their title, and you then have to read the article to find out it's only been done in mice. "en-mice'd/en-micing" is a term for mods editing titles, here :D

      • asdff 21 hours ago

        Lay people act like this is a trump card but this is just how science is done. You can't really perform this in humans without having some data that it may very well work. Mice have been pretty good models for cancer biology. Nature Biotechnology is also a good and selective journal.

        • pasttense01 15 hours ago

          If you ask: out of all the studies which have done well in mice what percent lead to successful drugs for humans: the answer is a very small percent.

        • CoastalCoder 20 hours ago

          Out of curiosity, are there examples of drug development that did poorly in animal models, but then did much better in human trials?

          I'm guessing this is rarely tested since animal modeling is usually a gating factor for human testing?

          • mrosett 20 hours ago

            Checkpoint inhibitors (which are the primary driver of improved cancer treatment over the last 15 years and generate > $50B/year in sales) generally don't look very good preclinically. Even their clinical data can be hard to interpret prior to a large scale trial, which led to them almost being shelved.

            The catch here is that only two targets (PD(L)-1 and CTLA-4) turned out to work well in humans. All of the other immunotherapies that looked mediocre preclinically turned out to also be mediocre or entirely ineffective in humans.

        • slater 21 hours ago

          I agree, I'm just mentioning it re: clickbait titles (not calling anyone out) vs. "oh, [xyz] hasn't been cured, there's just some promising results in mice"

The leap from mice to human might be greater than from nothing to mice.

The clickbait title serves as a boost to researcher's motivation.

Something that "essentially tells the body to ... stimulate the immune system" usually would cause high fever? I didn't see this mentioned so wondering if it is or isn't a complication with this.

I still hate those articles title with all my heart.

Is there a way to ban lies about cancer vaccines, fusion reactors, and infinite battery storage ?

Sure, okay, people are working on that, and they're making small incremental improvements and that's good for them ; and unfortunately they need to advertise to secure more funding for the later incremental stage of their research. I understand that.

But please stop with the nonsensical "cancer vaccine", "miracle cancer treatment", "cancer breakthrough" etc... This is an insult to everyone who lost a loved one to cancer.

Cause I'll be _really_ happy when a _real_ cure happens (as in, when anyone can go the their doctor, for real, and get a real "cure", and they have no cancer after that, and it's a simple as getting a cure for, well, you know, the diseases that we "cure", and that are definitely not cancer ?)

But this is not today. Today we "deal" with cancer, we "spare" people some time, we squash it a bit and maybe save a couple of years if you have the "lucky" kind of cancer - and that's great, and let's continue doing that.

But enough with the headlines.

Play it like Apple, please.

Tell me about it when I can buy it.

  • hughw 19 hours ago

    But we know how to read critically, don't we? When I read it, I searched for and noticed "mice" and "proof of concept" in the text, and understood the limited claims they're making. I'm glad to learn about this incremental progress because cancer immunotherapy seems a promising avenue.

    • phtrivier 18 hours ago

      Our ability to "read critically" is not incompatible with the expectation that other people will "write honestly". If it's incremental and a promising lead and it works only in mice, there are an infinite number of titles that are closer to the truth than "universal cancer vaccine".

      Otherwise, I'm going to start posting things about that "AGI" that I was able to train, and that can think () !!! Trust me, it's in Rust !!

... in mice.

Don't get me wrong, it's encouraging to see research in this field progressing. But there is a long list of treatments that work in mice that do not work in humans.

I'll temper my enthusiasm with a healthy dose of pragmatism.

  • amelius 20 hours ago

    Of course it is in mice. If they were in the human testing phase, you would have read about it long before on HN!

    • phtrivier 20 hours ago

      But the title "inadvertently" forgets to mention that the "universal cancer vaccine" is not universal, not a vaccine, and does not cure cancer unless you're a rodent.

      So, of course it gets to the HN front page, because the title is so catchy !

      I guess the only way to make it go to the front page faster would have be to label the article : "MIT alumni-founded, Standford-based, YC-funded startup creates universal cancer vaccine with AI, in Rust"

      I feel such a bore, but seeing characters like Deadpool walking around in real life makes my eyes roll. Although interestingly Borat's universe is this one, well his show really does blend fiction and reality.

      Then again politicians are gaslighting us left and right (saying things not far from "chocolate rations have gone up"), just like Borat pretending to be an uncouth journalist from Kazakhstan...

      Hah the context of the 1984 reference hits hard:

      > It appeared that there had even been demonstrations to thank Big Brother for raising the chocolate ration to twenty grams a week. And only yesterday […] it had been announced that the ration was to be reduced to twenty grams a week. Was it possible that they could swallow that, after only twenty-four hours? Yes, they swallowed it. [...] The eyeless creature at the other table swallowed it fanatically. passionately, with a furious desire to track down, denounce, and vaporize anyone who should suggest that last week the ration had been thirty grams. Syme, too - in some more double complex way, involving doublethink-Syme, swallow it. Was he, then, alone in the possession of a memory?
