Cancer Resistance Technique Moves To Human Trials
TaeKwonDood tips us to news that a new cancer resistance treatment is going into clinical trials after being quite successful at eradicating cancer in mice. Researchers discovered that certain white blood cells called granulocytes from cancer-immune mice were able to cure cancer in other mice. Now, doctors are putting out the call for healthy granulocyte donors in order to test how well it works on humans. The article quotes lead researcher Zheng Cui saying, "In mice, we've been able to eradicate even highly aggressive forms of malignancy with extremely large tumors. Hopefully, we will see the same results in humans. Our laboratory studies indicate that this cancer-fighting ability is even stronger in healthy humans."
This strikes me as a kind of fast-track immunization, i.e. getting the relevant antibodies into a person's immune system quickly before an infection can take hold. Rather than having to spend time developing the relevant treatment, simply borrow from another human who already has the necessary lymphocytes. Nice!
I'm aware of the correlation between infection and various cancers - I had Hodgkins Lymphoma a few years ago myself.
"I bless every day that I continue to live, for every day is pure profit."
...young scientists, who discover that the real cure for cancer was inside of them all along!
Progress is slow when new medicine is constantly under attack and being made...

If you are diagnosed with cancer today -- any kind of cancer, and remember the word "cancer" covers an enormous range of disease -- your chances of long-term survival are much, much better than they were five years ago. Five years ago, your chances were much better than ten years ago. Etc. The general public loses interest when a promising new treatment turns out not to be The! Cure! For! Cancer!, but yes, research does make its way from the lab to the bedside. Probably no new medicine or treatment technique will ever cure all cancer, but there's a good chance it will take care of a significant portion of a certain type of cancers -- which is, of course, of infinite interest to those diagnosed with that particular disease.
The correlation between ignorance of statistics and using "correlation is not causation" as an argument is close to 1.
Definitely glad to see this story. It's the first of a number of techniques to reach clinical trials that actually show real promise.
I don't qualify as a patient participant as I still respond to conventional therapy. Hopefully they'll still be conducting trials if that changes, or will have expanded them to include patients who are still being treated conventionally.
It'll definitely be interesting to see the results if they expand trials to include patients with aggressive tumors. The patient requirements, while not explicitly saying so, eliminate consideration of such patients. Once you no longer respond to therapy treating an aggressive cancer, the likelihood of having a > 6 month survival rating is basically nil (thus disqualifying you from the study). I can understand the rationale to not unnecessarily skew the initial trial results when they can get good data from patients with less aggressive cancers, but if/when the trials go after the fast killers it will definitely show the true potential of this particular cancer weapon.
Here's to hoping for positive results. The other nice thing about this therapy is that, since it is not drug-based, it is not locked up by one single pharmaceutical company. Hooray for open source medical therapies.
People who protest against using animals for testing new drugs or therapies would be well advised to take note of how this advance relied on years of animal research. While unnecessary cruelty to animals is to be abhorred (and yes there may be times when suffering is necessary) this shows that the rewards may be significant.
It's interesting that (much of) the scientific community and christian fundamentalists agree upon this point. It's due to the christian fundamentalists' view that God gave Man dominion over all the animals; not because of any appreciation or understanding on their part of the scientific method.
Not to be rude but you, good sir, are talking out of your ass. My brother was 14 when he died of pancreatic cancer. He wasn't suffering from "psychological conditions," he wasn't "unwilling to forgive someone" for some imaginary event that caused his body to somehow psychosomatically create the cancer that killed him. You want to know what I think caused his cancer? I think it was Doe Run and Dow Chemical polluting the crap out of the everything around them. We lived in Herculaneum, MO for the first 10 years of his life, and it wouldn't surprise me in the least if that was the cause. Your touchy-feely approach on this smacks of New Age "science" with nothing to back it up. "Oh it was their own feelings that did it!" Right. I suppose next you're going to start telling people that Thetans are causing all the world's ills.
God, schmod. I want my monkey man!
Recently, several people, in clinical trials, have been cured!! from metastatic (widespread) malignant melanoma - which is usually a 1-2 year death sentence after it has metastasized.
Many childhood leukemias have a 80% survival rate, whereas 30 years ago it was a 80% death rate.
Osteogenic and Ewings sarcoma (primary bone cancers) now has an 80% 5 year survival rate, 20 years ago it was a 20% 5 year survival rate. Now, 90-95% of the kids I operate on now get to keep their arms and legs with artificial bones. 30 years ago, they mostly had amputations.
Much of the advances have been from improved detection (MRI/CT/PET scans), and newer chemotherapies - ALL which have been based on animal research (F U PETA!)
Many scientists and MDs feel that immuno-therapy (using the bodies own immune system to fight/kill the cancer) will be the most fruitful research, and probably the most successful in the long run.
..........FULL STOP.
I just spent 2 days reading a few articles about this general area of research in last week's New England Journal of Medicine, so let me try to explain this to my fellow /.r's who so generously explain to me about warez and the penguin.
Doctors now believe that cancer goes through several stages before it becomes a problem. Cells become cancerous all the time, but usually the immune systen destroys them. To simplify a bit, immune cells such as dendrocytes (which is the hot immune cell these days) recognize cancer proteins. Dendrocytes take a piece of the cancer protein to a T cell, and the T cell kills the cancer cells. There's a great explanation of the immune process on Kimball's Biology Pages http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/A/AntigenPresentation.html, and if you take a few minutes to figure it out you'll understand one of the most amazing discoveries of the last century.
The reason we get cancer is that sometimes that process doesn't work. All it takes is one time during your lifetime when a cancer cell "figures out" a way to evade the immune system, and the cancer takes off.
It obviously occurs to doctors that it would be cool (and probably win a Nobel prize) if they could figure out some way to goose the immune system into fighting cancer, just the way they goose it into fighting viruses with vaccines.
One guy who tried that was Steven Rosenberg http://en.wikipedia.org/wiki/Steven_Rosenberg at the NIH. Rosenberg took melanoma cells from patients, and tried to stimulate the patient's immune system with a molecule called interleukin-2 that cells use to signal immune attacks. I remember reading about that around 1984, I think. The cancer slowed down but it came back. Rosenberg has been working on it ever since.
I remember seeing a cover headline in Fortune magazine back then about Rosenberg, to the effect, "Cure for cancer." (No question mark.) Do you suppose the media hype these things?
In order to understand cancer research, you have to understand that they can kill cancer cells in laboratory bottles, they can cure cancer in mice, but when they try to kill cancer cells in humans, time and again, it doesn't work. When it finally works in humans, that's news. The other thing you have to understand is that there are many treatments that make cancer tumors shrink or disappear for a while, but they usually come back. Cancer patients don't want the cancer to go away for 6 months -- they want it to go away forever. There are a few cancers that can sometimes be cured, like testicular cancer and childhood leukemia, and maybe some prostate cancers, but most of the time, for the big 3 (colon, breast, lung) oncologists are just trying to extend life. Of course, if you're 65 and your doctor can keep you alive for another 20 years with colon cancer or leukemia, that's not so bad. Most of the successful treatments for cancer extend the life of a cancer patient from, say, 20 months to 25 months, or 40 months to 45 months, but sometimes they get a really big jump, and for people with chronic myelogenic leukemia, imatinab (Gleevec) can extend their lives indefinitely.
Anyway, the really big news is that somebody actually managed to get a treatment like Rosenberg's to work on a real human with melanoma, who seems to be cured after 2 years. This was published in the New England Journal of Medicine, Treatment of metastatic melanoma with autologous CD4+ T cells against NY-ESO-1, Naomi Hunder et al., 358:2698 http://content.nejm.org/cgi/content/short/358/25/2698 In the past, they've gotten melanoma (and kidney cancer) to regress for a while, but it came back. This time it seems to be gone for good -- in one patient.
Basically, they had a patient with melanoma that had spread to his lungs. He had T cells that
Of course when the whacko extremists are the only ones still dieing of cancers it'll be because of a gov conspiracy to kill them off.
Think of it as evolution in action.
