I read the actual paper.

It achieved complete remission with hematopoietic recovery in 18 of 60 (30%) patients, and remission without hematopoietic recovery (so still likely need a bone marrow transplant) in another 5 of 60 (8%), and "morphological leukemia free state" (leukemia treated, but not cured?) in 9 of 60 (15%). So very positive results in 32 of 60 (53%).

There was no response in 19 of 60 (32%), worsened disease in 7 of 60 (12%), and 2 of 60 (3%) were not reported on.

This drug only works on KMT2Ar and NPM1 variants of leukemia, which make up about 10% and 30% of all leukemias, respectively.

The rate of complete remission for the KMT2Ar is normally 9% with usual treatment, but 33% with the drug in this trial.

The results for survival time were written in a slightly confusing way, but I think the median survival time was 7 months for all patients regardless of remission status. I have no idea why they didn't split up the survival curves between those in remission vs those not in remission.

TLDR: Incremental improvements that might help increase remission rates in some leukemia patients with 2 specific gene mutations comprising 40% of leukemia cases, but it's not a miracle drug.

Hopefully we can make this prohibitively expensive so the treatment actually helps as few people as possible. The real promise of this medicine is that insurance companies will make a ton of profit from this.

It doesn't seem like that - the numbers still seem really good if YOU had that one special type of cancer, it would mean that you had a significantly better chance with this treatment.

I don't think that a cancer cure will come in the form of one treatment for ALL (which would be very nice), but it's going to be attacking specific forms and variations.

It's always that way.

As a scientist, we work extremely hard only to be undermined by reporters who cause the public to lose faith in scientists.

Scientist: Our clinical trial for a new therapy saw 18 of 60 patients get complete remission. We would have expected about 6 of 60, so this is an improvement.

Clickbait article: New therapy sees cancer VANISH in 18 patients.

Scientist: 😥

Public: OMG HOW MANY TIMES HAVE WE HEARD "SCIENTIST CURES CANCER" ITS ALL LIES AND BULLSHIT

Scientist: 😞

Pedantic: KMT2A-R (lysine’s amino acid abbreviation is K, MethylTransferase 2A - Rearranged). For the hematologists and oncologists from a while ago, KMT2a used to be called MLL. Nasty disease.

KMT2a is about 4-5% of acute myeloid leukemia in adults, maybe 20% in kids (but kid AML is rare, their leukemia is mostly ALL, although KMT2a can also be rearranged in ALL, because MLL stood for “mixed lineage leukemia” cause it couldn’t seem to make up its mind which type it was). Sorta don’t think it shakes out to an actual 10%, but if you look at the cases where people do badly it’s enriched.

NPM1 is a common form of AML, 30% seems about right…just for AML. But when you factor in CLL, CML, and other forms of leukemia, it’s not 30% of all leukemias.

TL;DR: this works in a disease where not much works. Percentages are hard when the denominator isn’t made clear, and this is especially true here because there are a lot of leukemia subtypes.

IOVERCALLHISTIOCYTES t1_jd53isa wrote

30% for AML seems good.

If you look at the metric of pathologist workflow and number of times we have to present at tumor boards…KMT2a leukemias are often a lotta work. Induction chemo often doesn’t work well. They recur all the time. They can be 20-30% of pediatric ALL that doesn’t respond to CAR-T (cell based therapy seen in the news for dramatic effect and obscene cost). If you could precondition patients with this type of leukemia before CAR-T more might be eligible.

Many of the patients aren’t healthy enough for a haircut either, so any treatment that doesn’t often kill em in the process (marrow transplant) is especially good.

I appreciate your knowledge on the subject!

I have a biology PhD but I'm not a cancer specialist by any means. I just try to read the actual science whenever an article like this gets posted to reddit to give a more realistic assessment of the findings.

IOVERCALLHISTIOCYTES t1_jd58ulq wrote

Reddits lucky to have someone like you summarize this stuff!

You’d get a kick out of KMT2a. The protein is..3700? residues, has a heap of domains, and gets cleaved into two, something like a 320kD and 180kD. The pull-down assays bring down a ton of things where many of the proteins correspond to mutations seen in cancer. Crystal structure was apparently a challenge.

I read every word of it, and several other write ups on it.

There is no treatment on earth that cures every form of cancer.

Every cancer treatment is for specific types of cancer.

This treatment results in complete remission with no need for bone marrow transplant in 30% of patients. And another chunk of patients have complete remission but still require a transplant. It is a cure for 1/3 of people with this type of cancer.

It’s crazy my Dad has had Leukemia for 8 or so years now??? Maybe a bit longer? It constantly comes back but he did an experimental treatment at Dana Farber when he was diagnosed and he’s the only 1/300 people still alive. My mom is not doing quite so well with throat cancer - currently on her 2nd round of chemo and it’s really not looking good. It’s pretty adorable watching my leukemia dad take care of my cancer mom… but damn the big C can go suck a bag of dicks.

Watched the Fungi documentary on Netflix recently - was amazed to hear that there are some mushrooms out there that can fight back against cancer - or more accurately - amplify your defenses exponentially.

Jesta23 t1_jd65dd2 wrote

I want to add some context to the term complete remission. I was almost killed because of the misunderstanding of it.

In Leukemia, a Complete remission is an outdated metric. Many years ago we had limited ability to detect cancer cells in bone marrow. If you run that test and dont see any cancer cells then it is termed as a complete remission. This sounds wonderful, and many drug companies use this as the basis for their reporting because it makes their drugs look better than they are.

Today, there are tests that can see cancer cells thousands of times better than a complete remission. What we as laymen would call a "complete remission." is actually called MRD negative in leukemia. Any study that does not mention MRD status of the patients is not reporting the full facts and using the term Complete remission as publicity to get investments.

EDIT: since someone pmed me to ask, When I was diagnosed I was given the option of several treatments. The one the doctor wanted me to accept was presented as "99% of patients on this plan have a complete remission in 6months, and it has far less side effects than these other treatments. So obviously I accepted that one. 99% chance of being cancer free? low to no side effects? fuck yeah sign me up doc!

After reading all night I discovered the real terminology in leukemia and found that the treatment I just signed up for had a 99% complete remission rate, but only a 47% MRD negative rate, and a 34% 5 year survivability rate.

While another option had no reported complete remission rate, because its a shitty outdated metric, but had a 88% MRD negative rate, and a 77% 5 year survivability rate.

The option that I was nearly tricked into accepting is far cheaper, and since I had just lost my job (due to being sick.) they were looking to save money.

I'm sorry to hear about your father, that's awful.

I've been living with CML since 2007. Today there's are a number of treatments that basically didn't exist before 1999. The breakthrough drug is called Gleevec, and now there are several generations of treatments beyond that. I feel lucky to have been diagnosed when I was. A decade earlier and I there's a good chance I wouldn't be here today.

bigwill6709 t1_jd66ywp wrote

Just some helpful context here for those reading your comment: this trial was done on patient with relapsed AML (it came back after having gone away) or refractory AML (meaning the cancer never actually got to remission). The standard treatment for relapsed/refractory acute leukemia is a bone marrow transplant, which is pretty toxic (more so than most standard chemo). Success rates of transplant are much better if you can get in remission prior to transplant. So having a drug that can help get people into remission is a big step forward.

Regarding the outcomes mentioned, there are many ways to try and measure if someone is in remission. Morphological remission just means when they looked at the bone marrow under the microscope, they didn’t see leukemia cells. The better measure of remission is MRD (Minimal Residual Disease), which is a test using a different method called flow cytometry that looks at individual cells and the markers they produce to find cancer cells. If MRD is negative, that’s considered better than morphological remission.

PocketDeuces t1_jd678yq wrote

Seems that way because every one of these articles is about a different kind of cancer. Even leukemia has 4 main types with a bunch of variations underneath. Every breakthrough is for a very specific type of cancer. There's no one size fits all "cure for cancer" and I suspect there never will be.

So far so good. I am getting for AML after chemo which seems to be a fairly newish use for it. I have been on it for 6 months and will stay on it for 6 more. Compared to the chemo, Sprycel ain’t bad at all.

Congrats on your remission.

PocketDeuces t1_jd6ajcp wrote

Glad to hear that. I didn't know that they give sprycel for AML. I have CML, and it's a common treatment for that.

Watch out for pleural effusion. If you have any trouble breathing, let your doctor know asap. Often times a 50mg dose works as well as 100, but without as many side effects.

sigrunrun t1_jd6c3zd wrote

Complete remission without hematopoietic recovery (CRi) means we don’t see leukemia in the bone marrow (<5% blasts) but their blood counts (white blood cells, platelets) are not back to normal due to the chemo side effects. The patient essentially no longer has leukemia so we call it a win. It does not necessarily mean that patients will have to have a bone marrow (stem cell) transplant in order to be “cured.” That is driven by a whole host of other factors not surprisingly is largely risk vs. benefit. Stem cell transplantation is very costly and toxic and many patients can not even find a match.

MLFS essentially means there’s no leukemia in the bone marrow but something still isn’t quite normal in the blood or marrow depending on which definition you use. For example NCCN criteria says that CRi your platelets and white cells are abnormal but your hemoglobin should be normal. If your Hgb is too low then you would be MLFS.

I agree it’s not a miracle drug by any means, but patients who are getting this most likely don’t have any other options so for them even a small percentage of success at prolonging their lives even a few 7 months is worth it. A 53% response rate is VERY good for adult AML - we still don’t really know how to “cure” it.

I hate click bait articles but this is unfortunately what is needed to get people (investors) excited in funding cancer and medical research

> worsened disease in 7 of 60 (12%)

Does this mean the leukemia worsened or the drug actually worsened the leukemia? They are definitely two different situations. It’s very possible that these people had very aggressive cancers and it slowed them or just had no effect but continued deteriorating.

Cancer is essentially the "final boss" for humans.

If any one human manages to avoid death from other sources for long enough, they will eventually die to cancer just due to how the human body works.

Cancer is basically just "there's something wrong in how your cells are reproducing and the body can't take care of it like it usually does." And all humans reach that point eventually.

It's just very unfortunate that some of us reach it well before others.

It’s kind of depressing to read the posts there regarding medical advancements because of that. It’s like “oh this new med seems great even tho it likely won’t come out in the next 15 years!” Then, even after it does, it would be so expensive and practically out of reach for the average person until it goes generic. There are several newer meds I’d love to try, but they are just so expensive for those of us in the US even with insurance.

If it makes you feel any better, the 5-year survival rate for all cancers combined has increased from 50% to 67% in the last 50 years, and there has been significant improvement in every single cancer category (except uterine cancer) which implies that the improved treatments have not been restricted to only a few rich people, but that therapeutic improvements have been more widespread.
