FOR THE PAST decade, two things have consumed large chunks of Malvern native Tom Kramer's time.

The first is his training regimen. Kramer, 46, is a practicing triathlete who will compete Saturday morning in the eighth annual Philadelphia Insurance Triathlon in Fairmount Park.

The second is the search for a bone-marrow match for his wife Pam, also a triathlete, who was diagnosed with a rare form of leukemia in 2000 and eventually willl need a bone marrow transplant.

At some point, Kramer made a creative decision to have those cumbersome obligations intersect. Desperate to spread the word about the importance of registering as a bone-marrow donor he estimates only 9 million people are registered Kramer embarked on a four-event quest over the span of 8 months to raise awareness.

"It was just me in the beginning," he said. "All I had was a banner and some testing kits."

Kramer completed a marathon, two Ironman half-triathlons and a full Ironman triathlon. Eventually his effort gained steam, finally culminating last year when the Kramers incorporated their hard work into the non-profit Racing to Register.

Using endurance sports as a platform, Racing to Register aims to enlarge the pool of potential donors for blood cancer patients in need of lifesaving bone marrow or stem cells.

"We think that the endurance part the reason we chose that platform is that you have to have a lot of endurance to go through that kind of treatment," Kramer said. "There is that marriage there if we can put ourselves through this, you can register."

Athletes that who join Team RTR complete the donor registration process and, in return, the program facilitates their endurance training through coaching, discounted gear and more.

While his wife's illness is what got him started, Kramer says the event has grown into something much bigger. With more than 2,100 registrants, RTR has produced four potential matches.

BANGALORE, June 22, 2012 /PRNewswire/ --

Adding an impetus to the already existing image of Bangalore being a healthcare destination of India, Columbia Asia Referral Hospital, Yeshwanthpur (CARHY), announced comprehensive bone marrow transplant (stem cell transplant) service on Thursday. This facility will give hope to many cancer patientsin and around Bangalore as there are very few hospitals in South India providing allogeneic transplant, which involves using stem cellsfrom a donor with a similar genetic makeup.

The bone marrow transplant (BMT) service will have a team of medical experts including clinical hematologist, oncologist, and other qualified doctors from allied specialties like pediatrics, infectious disease specialist and trained nurses for stem cell transplant, state-of-the-art HEPA filtered room, ICU, 24 hrs blood bank services and radiology services for providing comprehensive care during stem cell transplant.

Addressing the media, Dr. Nandakumar Jairam, Chairman and Group Medical Director, Columbia Asia Hospitals,said, "We are happy to announce allogenic bone marrow transplant service at our hospital in Yeshwanthpur, over and above the existing autologous transplant service. This will enhance comprehensive bone marrow transplant treatment delivery; a dire need for the people of Karnataka and neighbouring states. This will also help many international patients who look for such a treatment in India."

"This facility is dedicated to providing end-to-end services including expert counsel from a clinical hematologist and an entire team of doctors and nurses providing the latest in medical advances to those suffering from blood cancer and some non-cancerous conditions affecting thebone marrow," said Dr. Satish, Consultant in Clinical Hematology, Columbia Asia Hospitals.

"Bone marrow transplant, also called hematopoietic stem cell transplant (HSCT), is a treatment optionfor certain cancers. With this launch, Columbia Asia Referral Hospital Yeshwanthpur becomes one among the very few centers in India to offer allogeneic bone marrow transplants. Till now, we were doing only autologous transplants which involved the usage of the patient's own stem cells. Now, we will be able to manage conditions like high risk leukemia's, myelomas and lymphomas," said Dr Satish.

"Some of the most effective treatments for cancer such as chemotherapy and radiation are toxic to the bone marrow.The marrow produces different cells that make up the blood such as red blood cells, white blood cells and platelets. The stem cells from the bone marrow are extracted before the administration of high dose chemotherapy and then reintroduced or transplanted to the patient so that blood cell production process is re-established in the bone marrow," addedDr Neelesh Reddy, Consultant Medical Oncology, Columbia Asia Hospitals.

In fact earlier stem cells were collected only from the bone marrow in the hip bones under general anesthesia. However with advanced technology and medical supervision stem cells can now be collected from peripheral blood after giving injections. Stem cells are then harvested by simple procedure called apheresis, (in the same way as dialysis is done) and the rest of the blood is returned to the person.

Long-time exposure to pesticides via inhalation may cause moderate to severe blood toxicity and reduction in the total number of bone marrow cells, leading to several degenerative diseases like aplastic anaemia, researchers at the School of Tropical Medicine (STM) here say.

The researches arrived at the conclusion from procedures performed on mice.

"As a whole, exposure to pesticides reduced the total number of bone marrow cells or, in other words, suppressed them," Sujata Law, assistant professor (Stem Cell Biology) at STM's Department of Medical Biotechnology, told IANS.

Bone marrow is the soft, flexible tissue found in long bones such as the thigh bone and the hip bone that contain immature cells called stem cells.

Stem cells, particularly the haematopoeitic stem cells (HSC) or the blood-forming stem cells can develop into the following types - red blood cells that carry oxygen, white blood cells that fight infection and platelets that help to clot blood.

So, in effect, bone marrow is the birthplace of these important cells.

"Bone marrow suppression leads to a number of degenerative diseases like aplastic anaemia, where the deficiency in the number of cells in the circulating blood (peripheral cytopenia) is the main feature," Law said.

The exact underlying mechanism is unknown but it has been concluded from the research published in the Journal of Environmental Toxicology that the microenvironment of the stem cells, in which they develop, is somehow deranged and this prevents their development into the various types of cells.

"In order to prevent degenerative diseases related to pesticide exposure, it is of prime importance that those handling pesticides take precautions like wearing protective clothing, including masks and gloves," she said.

French scientists revive stem cells of dead people

A group from the Pasteur Institute was able to reactivate muscle stem cells from deceased persons after 17 days, which functioned normally after transplant...

by Fabrice Chretien

French scientists were able to revive stem cells of muscle and bone marrow from persons who were already dead for 17 days, reports the journal Nature Communications in a paper released on Wednesday (13th) in France.

A team of researchers from the Pasteur Institute demonstrated that it is possible to reactivate the muscle stem cells from human cadavers and transplant them to make new ones born in perfect condition.

The scientists found that these cells did not die with the person. That's because they reduced their activity to a minimum and, after discarding the mitochondria (small bodies that help with breathing), were in a state of hibernation.

Thus, cells could survive even in an environment so hostile, without oxygen and in the middle of an acid bath, as well as in the case of a muscle injury, "sleeping and waiting out the storm," as Professor Fabrice Chrtien affirmed to the newspaper Libration.

"This reserve of stem cells could serve to make bone marrow transplants used to treat leukemia and blood diseases, among other conditions. They could also address the lack of donors," said Chretien, who led the study alongside researcher, Shahragim Tajbakhsh.

Despite the advances that have also been successfully tested in rats, the experiment showed an increase of one type of substance called ROS, which, in turn, has an incompatibility with the cells and genome, Professor Jean-Marc Lemaitre pointed out to the paper, Le Figaro. Due to this fact, the study still needs to determine whether these new cells, even in perfect condition, can hide still undetected malformations.

BETHEL, Vt. -

Amelia Lincoln loves to garden. But so far this planting season, she has had to sit it out.

"It's been a long haul and we try to keep a pretty positive attitude about everything. So, I generally could feel worse right now," she said.

Lincoln's immune system is fragile. For the past six weeks, she has been undergoing chemotherapy for cancer.

"I have acute myelogenous leukemia," she said. "I have a leukemia that came back after a stem cell transplant two years ago."

She had been in remission, but the aggressive cancer in her bone marrow is back.

"It's a change of priorities, but what would anyone say if their spouse was sick," husband James Patterson said.

Lincoln needs another transplant at the Norris Cotton Cancer Center. But right now, she has yet to find the perfect match.

"We used to use bone marrow specifically for a bone marrow transplant. Nowadays, we can use medicines to stimulate a patient's bone marrow cells into the blood. We can collect those bone marrow cells in the blood-- called peripheral blood stem cells-- and use those cells for the transplant," said Dr. Kenneth Meehan of the Norris Cotton Cancer Center.

A donor drive Tuesday in Randolph Center could increase Amelia's odds. No needles-- just a swab.

Bethel woman waits for marrow match

A FAMILY is waiting anxiously to see whether a bone marrow transplant, made possible by a rare prison transfer, has saved a boy's life.

Gao Yong, who began a 10-year sentence for burglary in 2005, was allowed to travel to donate bone marrow stem cells for his nine-year-old son, Jun Jie, who has leukemia.

Gao, who had been serving his sentence in east China's Zhejiang Province, was transferred to a prison in southwest Guizhou Province to be closer to the Xinqiao Hospital in Chongqing where Jun Ji had been taken after all possible treatments in his hometown of Zunyi in Guizhou had been exhausted.

Jun Jie was diagnosed with leukemia around the end of 2011.

Doctors at Xinqiao said Jun Jie required a bone marrow transplant, but tests showed none of his other family members were a match. His only hope was his father.

In February, after a blood sample was sent to the jail holding Gao some two hours away by air, good news came back - they matched.

Too weak to travel

"At that time, Jun Jie had become too weak to travel, so I went to judicial departments both in Zhejiang and Guizhou to persuade them to transfer his father to the Xinqiao Hospital,'' his mother Luo Jing said.

In March, Gao was transferred to the prison in Guizhou to prepare for the operation. On June 9, 10 officers escorted Gao to Chongqing.

It is very rare for a prisoner to come out of their assigned jail for as long as a week, noted the head of the escort team.

Unveilling stem cells

LAWRENCE SERETSE Correspondent

Cryo-Save, the European company that intends to establish the first stem cell bank in Botswana says stem cells do not have just one function. They can themselves become or create other types of cells such as blood cells, brain cells, tissue cells, muscle cells and the like. Stem cells can be found in every person but they are much more numerous in the body of a foetus.

There are three types of stem cell banking namely, the baby stem cell banking which is the preservation and storage of cord blood and umbilical cord tissue. Adult stem cell banking is the preservation and storage of peripheral blood (from blood stream for bone marrow transplants) and fatty tissue stem cells.

The reproductive cell banking deals with the preservation and storage of eggs and sperm for future fertility treatments or artificial insemination purposes. Studying stem cells helped humans understand how they transform into the dazzling array of specialised cells that make us what we are. Some of the most serious medical conditions, such as cancer and birth defects, are caused by problems that occur somewhere in this process. A better understanding of normal cell development has allowed scientists to understand and perhaps correct the errors that cause these medical conditions. Many support stem cell research because it has the potential to provide solutions to a wide variety of medical conditions and diseases.

Stem cell research could even lead to a cure for some of the most traumatic injuries and diseases. Stem cell treatments cure over 70 diseases and disorders like Leukemia, Lymphoma, blood cancers, bone marrow disorders like Aplastic anaemia, sickle cell, Diabetes, Alzheimer's Disease, heart disease, stroke, birth defects, spinal cord injuries, ability to replace or repair organs and cancer.

This is just half of it. If one just looked at the benefits one might wonder why stem cell treatments are not in wide use. The shortcomings of stem cell research are often fears of what could result from such knowledge and the moral implications of using the stem cells. There are worries that humans should not try to play God. "Relating bodies have to pay extra caution and determine if we really need these banks. Again, some researchers may be coming to dig stem cells in Botswana, since there maybe restrictive laws in their countries.

"The unsuspecting citizens may end up giving up their stem cells for money," says Iqbal Chand, the CEO of Diagnofirm Medical Laboratories. He gave a scenario from recent publications that a patient in Berlin was cleared of HIV after stem cell treatment for leukemia.

"We do not even know how true it is and if it was the stem cells that cured his HIV. Even if it is, it is one person in a million so there is no assurance," Chand pointed out.

Another big issue with stem cells research is superstition. In most African communities, the umbilical cord must be buried after birth because it is believed that anyone with access to it could exert some spiritual influence on the child. This has led to uncertainty towards cord tissue and cord blood storage in most African societies. However, with the success of transplants making the headlines, more and more people are willing to donate adult stem cells to save lives.

NEWORLEANS- She was only in kindergarten when doctors gave her family the bad news.

Now she's one of the first in Louisiana to try a new treatment for people who get gravely ill after a bone marrow transplant.

The last three years of Sami Smith's life have been physically and emotionally painful.

"I literally, they try to scare me and they can't, because I've been through the scariest thing that you can," said Smith, 9, of Ponchatoula.

Her mother noticed she was napping more and bruising. Doctors diagnosed AML, a type of leukemia or blood cancer. Had she not gotten to the doctor then, she would not have made it much longer. A Child's Wish sent her to Disney World. The good news, one of her teen sisters Mary Hannah, 13, was a good bone marrow match. The transplant worked and Sami was cancer free.

Then devastating news. Sami got a condition called GvHD (Graft-versus-host disease) where the new marrow launches a painful attack on the recipient's body. It's the leading cause of transplant-related death.

DOCTORS in Sweden successfully replaced a potentially-fatal blocked vein in a 10-year-old girl with one grown from her own stem cells, according to a study published today.

The team - from the University of Gothenburg andSahlgrenska University Hospital - accomplished the feat by populating a section of vein from a dead donor using stem cells gleaned from the girl's bone barrow.

"The new stem-cells-derived graft resulted not only in good blood flow rates and normal laboratory test values but also, in strikingly improved quality of life for the patient," the study's authors wrote in The Lancet.

The successful feat also "opens interesting new areas of research," they added.

The operation marked the latest step in scientists' ability to create replacement organs for transplant.

In 2010, doctors at London's Great Ormond Street Hospital made history by successfully transplanting a donor windpipe into a young boy, also aged 10, that was regenerated inside his body using his own stem cells.

In the latest instance, a 3.5-inch (9cm) section of groin vein from the donor was stripped of any living cells and "recellularised" with new cells grown from stem cells taken from the girl's bone marrow.

Techniques that use stem cells from a patient's own body carry the major benefit that they do not provoke an immune response. In the Swedish case, one alternative treatment option was a liver transplant, which would have required a lifetime of immunosuppressants. The work was funded by the Swedish government.

Vein grown from girl's stem cells

LONDON: Scientists have successfully transplanted a vein made from a 10-year-old girl's own stem cells into her body. It is the first time such an operation has been reported and marks an important step in the practical ability of doctors to use stem cells to grow replacement cells for damaged or diseased tissue.

Writing in the medical journal The Lancet, a team led by Professor Suchitra Sumitran-Holdgersson, of the University of Gothenburg in Sweden, described how the girl had a blocked hepatic portal vein, which takes blood away from the gut and spleen to the liver.

The blockage can lead to complications including internal bleeding, developmental problems and even death. The usual treatment for the condition is to remove the blocked vein and replace it with sections of healthy vein from other parts of the body.

The team instead grew a vein for the young girl using her own bone marrow stem cells.

They started with a nine-centimetre section of vein taken from the groin of a donor and stripped it of its cells, leaving behind a tubular protein scaffold. This was seeded with the girl's stem cells and the resulting vein was transplanted into the girl.

The procedure restored blood flow out of her liver immediately.

''The patient increased in height from 137 to 143 centimetres and increased in weight from 30 to 35 kilograms in the one year since the first operation,'' the authors wrote. ''Although we undertook no neurocognitive tests, the parents reported that the patient had enhanced physical activity (increased long distance walks of two to three kilometres and light gymnastics) and improved articulated speech and concentration power in school activities.''

Nine months after the operation, the vein had constricted slightly in size and this was corrected in a follow-up procedure. Most significantly, scientists found no antibodies for the donor vein in the girl's blood. Her body was not rejecting the transplant because it was recognised as being made of her own cells.

''The young girl in this report was spared the trauma of having veins harvested from the deep neck or leg with the associated risk of lower limb disorders, and avoided the need for a liver or multivisceral transplantation,'' Professors Martin Birchall and George Hamilton of University College London wrote in an accompanying commentary article in The Lancet.

BOCA RATON, Fla., June 13, 2012 (GLOBE NEWSWIRE) -- Good Morning America co-host Robin Roberts' decision to go public with the fact that she has a rare blood disorder was courageous and sheds light on the need for more bone marrow donors in the United States.

"In Robin's case, her sister turned out to be a perfect match, but the fact is, about two out of every three patients who need a transplant won't find a match in their family and will need to reach out to strangers to help save their lives," said Jay Feinberg, CEO of Gift of Life Bone Marrow Foundation, an international bone marrow registry based in Boca Raton, FL.

Approximately 10,000 people are diagnosed each year with a blood disease in which a bone marrow transplant could save their life, yet only half receive one. That is why the more people who are willing to donate, the better the chance of saving a life.

Feinberg knows that all too well. He was diagnosed with Leukemia in the early 1990s. He found his match in 1995 after more than 50,000 people were tested worldwide. He turned that grassroots movement into the not-for-profit Gift of Life Bone Marrow Foundation to get more donors into the worldwide registry and educate the public on the importance of donating. For its part, Gift of Life has facilitated more than 2,500 matches in its history and entered more than 200,000 people into the registry.

"It only takes one match to save a life, and that's what keeps us passionate and focused every day," said Feinberg, who found his match from a young woman who registered at the very last marrow drive organized for him. "The fact that someone as high profile as Robin Roberts is willing to share her personal story with the world will create a lot of new interest in people willing to become donors and to that end, that's a very positive thing. We wish her well in her upcoming treatments."

Gift of Life Bone Marrow Foundation, through its network of life-saving volunteers, organizes dozens of bone marrow drives per year around the world. Feinberg said becoming a donor is easy. A cotton swab is rubbed on the inside of the mouth to collect cells used for tissue typing. That information is then entered into the registry where anyone needing a transplant can turn to see if they find someone compatible. If a match is made, the donor is notified by phone and then undergoes one more test to confirm he or she is a perfect match. If so, the donor then undergoes a complete physical exam, and then the donation procedure, which involves either the taking of blood stem cells from the arms, or bone marrow from the hip. Those life-saving cells are then transplanted into the sick patient. The donor's marrow will eventually replenish itself. On average, one in 1,000 of Gift of Life donors is asked to donate every year.

Robin Roberts' Personal Story Highlights Need for More Bone Marrow Donors in the United States

By Makiko Kitamura - 2012-06-13T22:30:00Z

The first vein grown from a patients own stem cells was successfully transplanted into a 10-year-old girl, potentially offering a way for those lacking healthy veins to undergo dialysis or heart bypass surgery.

A team led by Michael Olausson of the University of Gothenburg took a 9-centimeter (3.5-inch) segment of vein from a human donor and removed all living cells, the Swedish researchers wrote in a study in The Lancet medical journal today. The resulting protein scaffolding was injected with stem cells from the girls bone marrow, and two weeks later was implanted in the patient, who had a blockage in the vein that carries blood from the spleen and intestines to the liver.

The result points to what may be a safer source of stem cells, the building blocks of life which can grow into any type of tissue in the body. Using cells from the patient may limit the risk that the immune system would attack the transplant, which can occur with tissue taken from healthy people and given to the sick. The girl hasnt developed signs of rejection, even without taking drugs to suppress her immune system, the researchers said.

The successful procedure establishes the feasibility and safety of a novel paradigm for treatment, the researchers wrote in the study. Our work opens interesting new areas of research, including trying to reproduce arteries for surgical use in patients.

The recipient had no complications from the operation, and a year later, has grown 6 centimeters and gained 5 kilograms (11 pounds) in weight.

Olausson and colleagues report suggests that tissue- engineered vascular grafts are promising, but one-off experiences such as the procedure they describe need to be converted into full clinical trials in key target populations, Martin Birchall and George Hamilton, professors at the University College London, wrote in a commentary accompanying the Lancet publication.

The study was funded by the Swedish government.

First Vein Grown From Human Stem Cells Transplanted

BOCA RATON, Fla., June 13, 2012 (GLOBE NEWSWIRE) -- Good Morning America co-host Robin Roberts' decision to go public with the fact that she has a rare blood disorder was courageous and sheds light on the need for more bone marrow donors in the United States.

"In Robin's case, her sister turned out to be a perfect match, but the fact is, about two out of every three patients who need a transplant won't find a match in their family and will need to reach out to strangers to help save their lives," said Jay Feinberg, CEO of Gift of Life Bone Marrow Foundation, an international bone marrow registry based in Boca Raton, FL.

Approximately 10,000 people are diagnosed each year with a blood disease in which a bone marrow transplant could save their life, yet only half receive one. That is why the more people who are willing to donate, the better the chance of saving a life.

Feinberg knows that all too well. He was diagnosed with Leukemia in the early 1990s. He found his match in 1995 after more than 50,000 people were tested worldwide. He turned that grassroots movement into the not-for-profit Gift of Life Bone Marrow Foundation to get more donors into the worldwide registry and educate the public on the importance of donating. For its part, Gift of Life has facilitated more than 2,500 matches in its history and entered more than 200,000 people into the registry.

"It only takes one match to save a life, and that's what keeps us passionate and focused every day," said Feinberg, who found his match from a young woman who registered at the very last marrow drive organized for him. "The fact that someone as high profile as Robin Roberts is willing to share her personal story with the world will create a lot of new interest in people willing to become donors and to that end, that's a very positive thing. We wish her well in her upcoming treatments."

Gift of Life Bone Marrow Foundation, through its network of life-saving volunteers, organizes dozens of bone marrow drives per year around the world. Feinberg said becoming a donor is easy. A cotton swab is rubbed on the inside of the mouth to collect cells used for tissue typing. That information is then entered into the registry where anyone needing a transplant can turn to see if they find someone compatible. If a match is made, the donor is notified by phone and then undergoes one more test to confirm he or she is a perfect match. If so, the donor then undergoes a complete physical exam, and then the donation procedure, which involves either the taking of blood stem cells from the arms, or bone marrow from the hip. Those life-saving cells are then transplanted into the sick patient. The donor's marrow will eventually replenish itself. On average, one in 1,000 of Gift of Life donors is asked to donate every year.

Robin Roberts' Personal Story Highlights Need for More Bone Marrow Donors in the United States

June 12, 2012

The use of stem-cells building-block cells that are harvested from embryos or adults to treat heart disease could rely on faith as much as it does science, after billions of dollars in research has not produced the results that researchers have been looking for.

Questions and concerns on the topic arose during the recent opening of the multi-million-dollar Scottish Center for Regenerative Medicine (SCRM) in Edinburgh, chaired by Sir Ian Wilmut, the renowned scientist whose Dolly the sheep clone in 1996, was a groundbreaking step in stem cell technology.

During the opening ceremonies of the Center, Christine Mummery of the Leiden University Medical Center in the Netherlands discussed how a 2001 claim, based on mice experimentation, indicated that bone-marrow cells could mend heart damaged by coronary disease, caused a mad rush of people to the clinics looking for a cure-all.

With nothing in the way of systematic research in animals, the first patients were being treated within a year, prematurely by Mummerys account. She argued that the paper that launched the mass stampede was completely wrong, and subsequent studies proved that. But despite the findings, the 2001 paper has never been withdrawn.

Norwegian professor Harald Arnesen in 2007 voiced his concerns over those heart trials as well. He concluded that they were not convincing and that one German team had achieved striking results only because the control group had done particularly badly. Arnesen called for a moratorium on this kind of stem-cell therapy, based on that research.

But neither Arnesen, nor Mummery, could deter clinicians. Another trial, the largest to date, began in January 2012 and included 3,000 heart-attack patients recruited from across Europe. The trial was funded by the European Union as well.

The idea behind the trials is straightforward. During a heart attack, a clogged blood vessel starves heart muscle of oxygen. Up to a billion heart muscle cells, called cardiomyocytes, can be damaged, and the body responds by replacing them with relatively inflexible scar tissue, which can lead to fatal heart failure.

What is notably surprising, explained Mummery, is that stem cells come in many different forms: Embryonic stem cells are the building-blocks of the body and have the potential to turn into all 200 cell types found in the human body. Adult stem cells, however, are limited in what they can do. For example, bone marrow stem cells only generate blood cells.

So, the 2001 study claiming that bone marrow stem cells could turn into healthy heart muscle was a surprising and exciting claim, although a bold move.

2009: Robin Roberts on her cancer

STORY HIGHLIGHTS

(CNN) -- Robin Roberts' battle against myelodysplastic syndrome, or MDS, is just beginning. The "Good Morning America" anchor will undergo chemotherapy before having a bone marrow transplant later this year.

"Bone marrow donors are scarce and particularly for African-American women," Roberts wrote Monday. "I am very fortunate to have a sister who is an excellent match, and this greatly improves my chances for a cure."

More than 10,000 people in the United States are diagnosed with blood-related disorders every year, according to the National Marrow Donor Program. Often the best treatment is a bone marrow transplant. During the procedure, a donor's stem cells are directly transfused into the sick patient's bloodstream. The patient's new cells multiply over time to create healthy bone marrow.

Unfortunately, the chance of finding a match on the national registry is as low as 66% for African-Americans and other minorities, compared with 93% for Caucasians.

Be the Match, the national registry, has 10 million potential donors, but only 7% are African-American. While the percentage is comparable to the overall African-American population in the United States (which is 12%), the registry is meeting only about a third of the needs for African-American transplants, said Dr. Jeffrey Chell, CEO of the National Marrow Donor Program.

Good Morning America anchor Robin Roberts made some news of her own today: Shes been diagnosed with a rare blood and bone marrow disease called myelodysplastic syndrome (MDS), a condition once known as pre-leukemia. Roberts, a breast cancer survivor, said she received the diagnosis several months ago and will receive a bone marrow transplant from her older sister later this year.My doctors tell me Im going to beat this and I know its true,she wrotewhen she announced her diagnosis. MDS is a pre-cancerous disorder half way between benign and malignant, said Dr. Martin Tallman, chief of the leukemia service at New Yorks Memorial Sloan-Kettering Cancer Center. It occurs when the bone marrow produces blood cells that break apart and disintegrate when they enter the blood stream.

When the marrow produces blood cells, theyre cracked, theyre fragile and faulty and they disappear, he said.Those disappearing blood cells leave patients with a low blood count, Tallman told msnbc.com, which can leave patients feeling fatigued from anemia, susceptible to infections like pneumonia and suffering from internal bleeding. The condition is curable, though it can also lead to fatal complications, primarily through infection, and some MDS patients develop leukemia.

MDS is more common in people over 60, and in most cases, doctors dont know why they developed the disorder, though genetic changes that take place as people get older are thought to be the cause. A minority of MDS patients develop the disorder following chemotherapy for cancer treatment.

Sometimes treatment for cancer can lead to other serious medical issues and thats what Im facing right now, Roberts said on the air this morning, noting that she beat breast cancer five years ago. Tallman explains that as chemotherapy drugs are killing cancer cells, they can also cause genetic changes in healthy cells, which can lead to whats called treatment-related MDS. We are able to cure certain disease but we pay a price, he said.

About 12,000 people a year are diagnosed with MDS in the U.S. each year, according to the American Cancer Society. The number of cases of MDS is rising, according to the Memorial Sloan-Kettering website, because there is a growing population of older people, and because patients are living longer after being treated for their first cancer.

For years, patients with MDS were treated with antibiotics and blood transfusions, but three new types of chemotherapy drugs to fight MDS became available starting in about 2004, said Tallman, a hematologist-oncologist.They are effective in about 30 percent to 40 percent of patients, he said. Some patients dont require treatments at all and can live with the disease; others are cured with the chemotherapy drugs alone. The only proven cure for MDS is a stem cell transplant, Tallman said, describing what it also called a bone marrow transplant.

Roberts says she is beginning a pre-treatment regimen of chemotherapy today before undergoing the bone marrow transplant. Her doctors gave her a good outlook, she wrote.

They say Im younger and fitter than most people who confront this disease and will be cured.

'GMA' host Roberts on illness: 'I will beat this'

(CNN) -

Robin Roberts' battle against myelodysplastic syndrome, or MDS, is just beginning. The "Good Morning America" anchor will undergo chemotherapy before having a bone marrow transplant later this year.

"Bone marrow donors are scarce and particularly for African-American women," Roberts wrote Monday. "I am very fortunate to have a sister who is an excellent match, and this greatly improves my chances for a cure."

While the percentage is comparable to the overall African-American population in the United States (which is 12 percent), the registry is meeting only about a third of the needs for African-American transplants, said Dr. Jeffrey Chell, CEO of the National Marrow Donor Program.

It's a disparity that's come up time and again. Last year, the death of Shannon Tavarez attracted attention because doctors were unable to find a bone marrow match for the young Broadway star, who had acute myeloid leukemia.

"It's absolutely critical to have more people on the registry," Chell said. "You're more likely to find a match with someone who shares your common ancestry or ethnicity."

Be the Match tests the immune system's genetic coding to determine bone marrow compatibility. The human immune system has evolved over thousands of years, which is why racial and ethic background is so important. For instance, European-Americans' ancestors may have survived the medieval plague, while African-Americans could have a natural immunity to malaria because of their ancestors' environmental pressures.

If a good match isn't found, the donor's immune system will attack the sick patient's "foreign" cells in a condition called graft-versus-host disease.
