Question a cure for 90% of cancers??????????

http://www.eurekalert.org/pub_releas...-mvp101215.php

PUBLIC RELEASE: 13-OCT-2015

Malaria vaccine provides hope for a general cure for cancer

UNIVERSITY OF COPENHAGEN THE FACULTY OF HEALTH AND MEDICAL SCIENCES

L
The hunt for a vaccine against malaria in pregnant women has provided an unexpected side benefit for Danish researchers, namely what appears to be an effective weapon against cancer. The scientists behind the vaccine aim for tests on humans within four years.

Danish scientists from the University of Copenhagen and the University of British Columbia (UBC) face a possible breakthrough in the fight against cancer, which may result in a genuine medical treatment for the dreaded disease. The hunt for a weapon to fight malaria in pregnant women has revealed that, expressed in popular terms, armed malaria proteins can kill cancer. The researchers behind the discovery hope to be able to conduct tests on humans within four years.

In collaboration with cancer researcher Mads Daugaard from the University of British Columbia in Canada, malaria researcher Professor Ali Salanti from the Faculty of Medical Health and Sciences, UCPH, has revealed that the carbohydrate that the malaria parasite attaches itself to in the placenta in pregnant women is identical to a carbohydrate found in cancer cells.

In the laboratory, scientists have created the protein hat the malaria parasite uses to adhere to the placenta and added a toxin. This combination of malaria protein and toxin seeks out the cancer cells, is absorbed, the toxin released inside, and then the cancer cells die. This process has been witnessed in cell cultures and in mice with cancer. The discovery has only just been described in an article in the renowned scientific journal Cancer Cell.

"For decades, scientists have been searching for similarities between the growth of a placenta and a tumor. The placenta is an organ, which within a few months grows from only few cells into an organ weighing approx. two pounds, and it provides the embryo with oxygen and nourishment in a relatively foreign environment. In a manner of speaking, tumors do much the same, they grow aggressively in a relatively foreign environment," says Ali Salanti from the Department of Immunology and Microbiology at the University of Copenhagen.

Ali Salanti's team is currently testing a vaccine against malaria on humans, and it was in connection with the development of this drug that he discovered that the carbohydrate in the placenta was also present in cancer tumors. Ali Salanti immediately contacted his former fellow student and now cancer researcher, Mads Daugaard, who is head of the Laboratory of Molecular Pathology at the Vancouver Prostate Center at UBC in Canada. In collaboration, the two groups have generated results, which they hope will provide the basis for a drug against cancer.

"We examined the carbohydrate's function. In the placenta, it helps ensure fast growth. Our experiments showed that it was the same in cancer tumors. We combined the malaria parasite with cancer cells and the parasite reacted to the cancer cells as if they were a placenta and attached itself," Ali Salanti explains.

Kills cancer cells

In collaboration, the two university research groups have tested thousands of samples from brain tumors to leukemia's and a general picture emerges to indicate that the malaria protein is able attack more than 90% of all types of tumors. The drug has been tested on mice that were implanted with three types of human tumours. With non-Hodgkin's lymphoma, the treated mice's tumours were about a quarter the size of the tumours in the control group. With prostate cancer, the tumours disappeared in two of the six treated mice a month after receiving the first dose. With metastatic bone cancer, five out of six of the treated mice were alive after almost eight weeks, compared to none of the mice in a control group. "We have separated the malaria protein, which attaches itself to the carbohydrate and then added a toxin. By conducting tests on mice, we have been able to show that the combination of protein and toxin kill the cancer cells," Mads Daugaard explains.

"It appears that the malaria protein attaches itself to the tumor without any significant attachment to other tissue. And the mice that were given doses of protein and toxin showed far higher survival rates than the untreated mice. We have seen that three doses can arrest growth in a tumor and even make it shrink," PhD student Thomas Mandel Clausen elaborates. He has been part of the research project for the last two years. It would appear that the only snag is the fact that the treatment would not be available for pregnant women.

"Expressed in popular terms, the toxin will believe that the placenta is a tumor and kill it, in exactly the same way it will believe that a tumor is a placenta," Ali Salanti states.

In collaboration with the scientists behind the discovery, the University of Copenhagen has created the biotech company, VAR2pharmaceuticals, which will drive the clinical development forward. The research teams working with Ali Salanti and Mads Daugaard are now working purposefully towards being able to conduct tests on humans.

"The earliest possible test scenario is in four years time. The biggest questions are whether it'll work in the human body, and if the human body can tolerate the doses needed without developing side effects. But we're optimistic because the protein appears to only attach itself to a carbohydrate that is only found in the placenta and in cancer tumors in humans," Ali Salanti concludes.

Re: a cure for 90% of cancers??????????

Yes, it's yet another venue and sounds promising, thanks for posting, Lani. If you read thru what they're currently seeing with mice, it's not a cure, though. It seems to slow down and partially revert growth. But it's not s cure. I will say, though, that if at some point in the future there is a sufficient number of working treatments that will help me survive with decent quality of life to reach average life expectancy (which I believe is in the early 80ies), then I'd be absolutely fine with that... That's only another 35 years or so... I guess what Im trying to say is: a cure would be great, but if MBC became a chronic disease, I could - quite literally - LIVE WITH THAT!

Wow is right ... and any progress towards making mbc a chronic disease is wonderful!

July 24, 2013: "Infected" Right Nipple and benign cyst removed, pathology report revealed Paget's, DCIS, and ILC 1.25 cm, ER+/Pro+/HER2 equivocal, Grade 2 under benign cyst, previous diagnostic mammo/ultrasound said I was perfectly healthy in both breasts.

Aug 18, 2013: MRI report says Left breast is perfectly healthy "consistent with previous studies".

Sept 2013: I insist on a bilateral mastectomy anyway. Too nervewracking to let left breast remain with higher risk after 3 cancers in right, nipple in right is already gone anyhow.

Sept 18, 2013: Bilateral mastectomy, 11 right nodes removed, ALL negative BUT -- ER+/PRO+/HER2+ tumor, 1.0 cm, Grade 2 found in a piece of "grossly unremarkable" breast tissue from prophylactic mastectomy of left breast, no nodes removed.

Oct 25, 2013: 13 left side nodes removed, ALL negative, Stage 1 across the board, NO RADS needed, YAAAAY! Port also installed.

Nov 25, 2013 Begin 6 rounds TCH.

March 10, 2014 Just finished 6th and LAST Chemo today, YAAAAAY!

March 24, 2014 Echocardiogram to make sure I'm still good for Herceptin every 3 weeks.

March 31, 2014 Echo results NORMAL, first Herceptin all by itself. Now if only my eyes would stop streaming from the Taxotere ... :)

April 21, 2014 Started Arimidex and therapy for "mild" lymphedema in left hand and arm

May 2014 Therapy completed, I have sleeves and gloves for both arms, a Flexi touch lymph pump to hook up to for an hour every day, and I've become an arm bandaging expert. :)

June 2014 Begin Fosamax to prevent osteoporosis; bone scan revealed osteopenia

Nov 17, 2014 FINAL Herceptin!

Dec 4, 2014 My right thigh muscle has been extra achy for days ... I discover a blister rash cluster on the side of my right thigh while taking a shower. Port appointment cancelled until Dec 17, my doc is working me in tomorrow afternoon to see me and the rash. My muscle at least feels less achy.

Dec 5, 2014 Yep, I have shingles. Boo! I start acyclovir and also have a prescription for a painkiller just in case for over the weekend.

Dec 17, 2014 Port is OUT!

January 2016 Shingles again and this time it started where my left breast (where the hidden HER2+++ tumor was!) used to be. My onc nurse got me a same day appointment to see my doc when I called and told her I had a rash on the site. The antiviral meds are working once again, though, so that is good news. :)

Such hopeful news!

Diagnosed June, 2006 HER2+++, ER- PR-, Grade 3, Stage IIB. Modified radical mastectomy, radiation, chemo, Herceptin, Tykerb 1 year. [*]In remission until 2/2010. Small tumor detected on chest wall during routine scan. 2/2010 surgery to remove tumor, started Herceptin/Tykerb, follow up radiation. [*]12/26/2010 - Off Tykerb due to allergic reaction[*]12/16/2014 - Have continued on Herception for almost 5 years now and remain NED. Discussion with onc re adding Perjeta to the Herceptin as another way of preventing recurrence. Still in discussion phase. 12/26/14 Onc applying for approval for Perjeta.
Perjeta approved and I received one infusion. It had an immediate impact to my lungs and I experienced difficulty breathing so.....I'm going to be sticking with just Herceptin. Still looking for a good vaccine program to enroll in.
