Leukemia Treatment Virtually Eradicates Cancer, Kills 'Pounds' Of Cancerous Cells
A new l eukemia treatment wowing even the researchers behind its creation, providing results beyond their wildest expectations. It is virtually eradicated cancer cells of leukemia in the first three patients have been tested.
In two of the first three patients the process was tested in the treatment completely destroyed the type most common leukemia according to MSNBC . In the third patient, the treatment appears to have reduced the cancer cells to 70 percent of what they were before.
"In three weeks, the tumors had been removed, in a way that was much more violent what we expected, "said senior author Carl June, MD said Penn Medicine .
Surprisingly, the breakthrough actually used their own T cells of patients for fight cancer, according to University of Pennsylvania press release . The researchers took the T cells of patients, went through the production facilities vaccines Penn, and then reintroduced into bodies after chemotherapy patients.
In terms more scientists, Penn Medicine
After removing cells from patients, the team they reprogrammed to attack tumor cells by genetically modifying them using a lentivirus vector. The vector encodes an antibody-like protein called chimeric receptor antigen (CAR), which is expressed on the surface of T cells and designed to bind to a protein called CD19.
Once the T cells begin to express the CAR, eliminating all activity of cells expressing CD19 of focus, including tumor cells and normal B cell CLL. All other cells in the patient not expressing CD19 are ignored by the modified T cells, limiting the side effects typically experienced during standard therapies.
The result was a very, very mean treatment effect showed very positive results within 28 days. . "In addition to an extensive capacity for self-replication, the infused T cells are serial murderers On average, each of T cells infused led to the deaths of thousands of tumor cells - and overall, destroyed at least two pounds of tumor in each patient " Penn said June .
Those who took part in the study were almost no options before treatment. The Press release states that short of a bone marrow transplant (leading in to a mortality risk of 20 percent and only 50 percent chance of recovery) none of these patients had alternative medical options.
the next step for scientists is to test the treatment of different types of leukemia. In the future, the process can be modified to address other types of tumors, including non-Hodgkin's lymphoma and acute lymphocytic leukemia.
Surprisingly, MSNBC reports that this radical treatment almost never happened. Funding for the experiment was apparently hard to find, and is one of the reasons the treatment has only been tested in three patients
