Training an Immune System To Kill Cancer
NotSanguine sends in a story about William Ludwig, a 65-year-old leukemia patient who underwent a new, experimental treatment that draws upon two decades of advances in molecular biology. Quoting:
"Doctors removed a billion of his T-cells — a type of white blood cell that fights viruses and tumors — and gave them new genes that would program the cells to attack his cancer. Then the altered cells were dripped back into Mr. Ludwig’s veins. At first, nothing happened. But after 10 days, hell broke loose in his hospital room. He began shaking with chills. His temperature shot up. His blood pressure shot down. He became so ill that doctors moved him into intensive care and warned that he might die. His family gathered at the hospital, fearing the worst. A few weeks later, the fevers were gone. And so was the leukemia. ... In essence, the team is using gene therapy to accomplish something that researchers have hoped to do for decades: train a person's own immune system to kill cancer cells."
While I think this is awesome, isn't this how I Am Legend happened?
WICKED COOL!!!
Is there a drug that requires a prescription or some sort of long term "treatment" that goes along with this procedure? If not, then it probably won't catch on in our wonderful privatized health care system, sadly.

It almost killed him, but he would inevitably die with cancer anyway. I think most patients will accept the risk. Now that he has 1 billions modified T-cells, possibly double that now, how do they plan on getting them out, or make the body accept them? Surviving cancer just to die from your own T-cells doesn't sound cool.

Our culture doesn't get smarter, it just finds new ways of being retarded.
Didn't we get this a couple weeks back?
Use HIV to reprogram his white blood cells to attack cancer?

Yeah, it's a dupe - but still a good story and encouraging for anyone that has had their lives affected by cancer. Here is the original post.
There's a company called Argos therapeutics http://www.argostherapeutics.com/ which uses proteins harvested from cancer biopsies to do the same thing. Last I checked, they were in phase 2 clinicals (efficacy testing). This is as close to personalized medicine as anyone is really able to do right now. Disclaimer: the only tie to the company that I have is that I interviewed there a couple years ago (didn't get the job unfortunately).

From a few weeks back. XKCD even did a comic on it.

Does this mean he's practically immune to cancer now? Like, he could smoke, drink, bqq and huff glue all he wants and not get cancer again... just like, maybe flu symptoms? I'm kinda jealous... I wonder what other super powers this might come with. (Reduced aging anyone?)
Whenever I see a suggestion about using the immune system in some new and novel way I cannot help but get worried about autoimune side effects.
I guess it is a bit irrational since vaccinations are basically stimulating the immune system to hit specific pathogens, and most of them are very safe as compared to other drugs, but I can't help but feel a bit uneasy about training the body to attack its own cells.
I can't gauge the validity of this research without a mention of subluxations as a calibration reference for my stupidity detector.
Blank until
American Cancer Society (cancer.org) and others similar institutions receive millions in donations from dying patients and their families, they live-off cancer donation and it is their primary business, they give away only about 1% to the research, while 99% goes to compensations, wages, and salaries. Lets see what they think about it.

Incredibly interesting nonetheless.

Awesome.
Sounds like something that would happen on Fringe - except on Fringe it would happen in under an hour.
While I think this is awesome, isn't this how I Am Legend happened?
Whatever happened in the movie was fanciful hand waving. This seems more comparable to inoculations. Fluids are introduced to the body, the body learns how to defend itself. Of course this high level perspective is about where the similarity ends.
He'd nearly kill the patient 3 times while making remarks about Cuddy's ass. And after the successful cure, he'd admit that the procedure had not yet been approved for use on rats, let alone people.
If it was Fringe, they'd be using alien DNA.
Have gnu, will travel.
Any chance of using this technique in a preventative way? I mean, could you give an inoculation to train your body to fight off the cancer when it first starts? Not an MD by any stretch.

If you read the article the treatment destroys ALL B-Cells good and bad while the new T-cells are present. With this I can certainly understand why the doctors are still reluctant to party. But it is definitely good to still have in the arsenal.
We can consider treatment a win when the disease is eliminated, the modified cells are gone, and normal biological operation is restored. But in the case of this treatment, if the special t-cells all die, then the reproduction of bad B-Cells may resume.
The really scary part of this all is the usage of HIV virus. Yes it's gutted but the wonderful thing about viruses is that they have the nasty habit of adapting to survive and if the theory on evolution is true, then eventually it's going to happen. The source of change may come from one of the cells being modified behaving in a way that is unexpected because it has damaged DNA and voila, that damaged DNA combines with the RNA to create something else. Heck, the RNA in the vector could become damaged and start another fun experiment to stop the new threat or it could just become wasted and die out.
For now I would just classify this stuff as interesting but definitely a little scary.
The chance of causing an autoimmune disease with this sort of treatment protocol seems enormous... Do you really think that nothing could possibly go wrong in training the body to kill its own cells of a specific narrow type?
I remember reading about a decades old cancer treatment technique that included fevers with very high temperatures. The physicians of the time claimed it was the body heat that killed the tumors.
Don't know how valid that is, but I know that a doctor told me once when I have fever not to take an aspirin just to lower the body temperature (unless it's dangerously high) because fever creates conditions for the body to fight the germs.
I wonder if they gave him his additional $60 for letting them take him apart, put some science stuff in him, and put him back together.
I think major cancer research groups (and HIV research groups) are all Pharmaceutical driven so that's why he wouldn't get any acceptance from them.
Oh and in the parentheses you obviously meant past right? Right???

Well, science is not far from fiction. In Old man's war, Scalzi writes about human clones with altered blood (it's called SmartBlood). This SmartBlood fight infections, keeps oxygen longer... and burns mosquitos :)
I think it is the way we go, to become genetically altered humans. But, really, HUMANS? Or something else? Hell with it. I don't care, just make it work for cancer.
There are animals that are completely immune to the effects of cancer and "live forever" (try and age most lobster-species - you can't because they literally "regrow" their cells all the time). There are human groups that are vastly more immune to certain types of cancer (and some vastly more susceptible) - and yet they would probably die if you gave them the flu.
Cancer is merely the result of a cell going haywire and instead of dying it reproduces like mad and keeps going. It's a DNA mutation caused by the presence of a chance of something going wrong every time a cell splits or reproduces. It's not some mystical, magical disease - we can pinpoint the cause virtually all of the time. The problem is that this makes it inherently more difficult to "attack" - it's not foreign, so to speak, it's just a normal part of us spinning out of control
At the moment, cancer is an inevitable thing caused by sheer statistics - if you live long enough, and have enough cells, one of them will "go rogue" and start a chain reaction that gives you cancerous tumours, etc. Thousands of years ago we rarely suffered from cancer because people just weren't living long enough to hit those sorts of probabilities (of course they happened, in the same way that babies can get cancer today, and they happened more if you were exposed to carcinogens, but it rarely had time for symptoms to affect your life so drastically as to kill you).
The problem is that, currently, treatment consists of obliterating obviously-cancerous cells plus a sufficient margin around them (to catch any we can't see) by a variety of pretty crude means (amputation, irradiation, chemical death, etc.). It's hardly "high-tech". In fact, our treatment of cancer is something that belongs in the era where we didn't suffer from it at all.
The problem with cancer is not "where's the magic pill", like it can be with actual diseases, viruses, etc. It's "how do we change your entire genetic makeup so this doesn't have a chance of happening". Hence what this article shows - you have to basically change the immune system cells artificially and then re-insert them into the patient.
You're basically changing their blood and immune system for one that their own genetics could *never* have produced (unlike, say, diseases that you can immunise against). In effect, you're genetically engineering parts for a human that attack the cancers they would normally be susceptible to.
10 years is optimistic, because of the sheer variety of cancers and the sheer magnitude of changes that can happen when ANY part of a DNA strand is "corrupted" when it's copied. And this is all cutting-edge stuff that has huge ramifications on your body (and just wait until people start equating "genetically modified" with things being inserted into human tissue!) and is pretty unique to each person / cell type / mutation. It can take 20 years to get something through clinical trials even if there are no adverse effects on tests.
Cancer will be with us for a LONG time. We may be able to control it "soon", i.e. years to decades, but to stop people dying of it is going to take a lot longer. It's the most heavily funded medical research there's ever been, and been running for almost all of modern medicine's existence - and STILL the most effective treatment is chemicals that kill parts of you, radiation that kills parts of you and a lot of hope and guesswork.
Computer analogy: If cells are like NULL-terminated strings stored on a hard drive, cancer is what happens when they lose the NULL. Eventually the drive will (inevitably) corrupt a single byte and if that loses the NULL terminator, everything can go tits-up. Our treatment at the moment consists of zeroing the drive areas around the string. It can work but there's nothing guaranteed about the rest of the data on the disk. This treatment is kinda like a RAID checksum algorithm running over the disk - a byte wrong here or there can be detected or fixed. The cure, though, is to make a drive that doesn't corr
The German trial got some of this press in mainstream news (although, arguably, not enough), and it was just a few weeks ago. So, this one probably won't get much press.
I read it on CNN.com two weeks ago. And the NY Times yesterday. AP sent it out on Sunday. So it is out there. Can't speak for TV news, though, as I don't watch TV news. For the reason you cited.
It sounds like it is right out of a sci-fi movie, where the cure has a kick to it,
looks like you might not make it after taking it, and yet after the storm passes, WOW, the results are amazing.
I hope they get to test this a few more times just to make sure, as well as follow said patient 10 years after,
as it is important to see if the cells will be ok 10 years later and not morph or mutate....I just hope they do not let

His fiancee has stage three breast cancer. I see it only as a way of coping with the pain and uncertainty that situation brings.
I have a relative in Ontario dying of cancer right now who might be willing to give it a shot.
Anyone in the field know if these guys can test on willing terminal patients? She's been given a year to live max.

I know this is off-topic, but is that why lobster tastes so good? It's like the veal of the sea?
Yes, that's mostly true. I wouldn't quite call it analog, since there's a checksum algorithm and all that (which still fails). But we have quite a number of redundancy in our non-cancerous cells to "restore from backup," so to speak.
Cancer itself is caused by immune system.
A friend of mine has this condition, and had this treatment.
He has had white hair all his life. After the treatment, he lost his hair, but it grew back black. They do not know if he's "cured", but he's doing better. His condition brought with it, many secondary tumors, and those have stopped.
These are my friends, See how they glisten. See this one shine, how he smiles in the light.
this was on the news weeks ago. hell, there's an XKCD about it. http://xkcd.com/938/ it was on SLASHDOT weeks before THAT. repost much?
