Here are just a few known risks of autologous stem cell treatments : Any time cells are removed from your body, there is a risk they may be contaminated with viruses, bacteria or other pathogens that could cause disease when reintroduced.
The predicted rate of survival was 62 percent . In allogeneic bone marrow transplantation, a person’s blood-forming stem cells are eliminated and then replaced with new, healthy ones obtained from a donor or from donated umbilical cord blood.
Stem cells survive much longer than ordinary cells , increasing the chance that they might accumulate genetic mutations. It might take only a few mutations for one cell to lose control over its self-renewal and growth and become the source of cancer .
The goal of a stem cell transplant in cancer is to prolong life and, in many cases, even cure the cancer . But in some cases, the cancer comes back (sometimes called relapse or recurrence depending on when it might occur after a transplant ). Relapse or recurrence can happen a few months to a few years after transplant .
For many patients, Stem Cell Therapy provides pain relief that can last for years. And in some soft tissue injuries, stem cell therapy can facilitate permanent repair.
According to analysis by BioInformant, the cost of stem cell therapy ranges from less than $5,000 for simple procedures to $25,000 or more for complex ones. In general, stem cell treatment procedures are paid out-of-pocket by patients, because they are not covered by medical insurance.
Multiple myeloma is the most common type. It accounts for 90 percent of cases, according to the Leukemia and Lymphoma Society. The National Cancer Institute’s Surveillance, Epidemiology, and End Results Program (SEER) lists myeloma as the 14th most common type of cancer . Survival rates .

This phase of the transplant can be very uncomfortable because very high treatment doses are used. Chemo and radiation side effects can make you sick, and it may take you months to fully recover. A very common problem is mouth sores that will need to be treated with strong pain medicines.
The transplant The stem cells will be passed slowly into your body through the central line. This process often takes around a couple of hours. The transplant won’t be painful and you’ll be awake throughout.
Meanwhile, doctors have found evidence of harm: Several people have gone blind after receiving stem cell treatments, according to reports in the New England Journal of Medicine and elsewhere. And two people died shortly after being injected with stem cell treatments in Florida, most recently in 2012.
What about the type of stem cells that more and more scientists are using instead of embryonic ones? Those are called induced pluripotent stem cells ; they come from the cells of already-born people. Unfortunately, any such cells that grow in the lab long enough can accumulate cancer -causing mutations, Loring said.
Distinct from the idea that cancers originate through activation of self-renewal mechanisms is the cancer stem cell (CSC) model of malignant propagation. The CSC model refers not to the cellular origin of cancers , but to the means through which established cancers propagate themselves , .
It develops when blood cells formed from the donor’s stem cells think your cells are foreign and attack them. Between 30% and 70% of patients with a donor stem cell transplant get some form of GvHD. It may be mild, serious, or even life threatening.
A stem cell transplant may help you live longer. In some cases, it can even cure blood cancers. About 50,000 transplantations are performed yearly, with the number increasing 10% to 20% each year. More than 20,000 people have now lived five years or longer after having a stem cell transplant .
