India’s blood stem cell donor registry remains limited in scale, significantly affecting patient outcomes. Given India’s vast population and immense genetic diversity, such a small registry severely decreases the probability of finding timely matches, said Patrick Paul, executive chairman, DKMS India.
Every five minutes, someone in India is diagnosed with blood cancer, and over 10,000 children are born with thalassemia every year. For thousands of Indians battling blood cancers and serious blood disorders, survival depends on finding a matched blood stem cell donor, yet India’s donor registry remains critically underdeveloped, he added.
For patients across the country, a blood stem cell transplant is not just an option for treatment, it is their only shot at survival. Despite a steady rise in blood cancer cases and inherited blood disorders across age groups, India’s blood stem cell donor registry remains limited in scale, significantly affecting patient outcomes, Paul told Pharmabiz in an email.
Unlike blood transfusions, stem cell transplants require a close genetic match between the patient and the donor, known as a human leukocyte antigen (HLA) match. Doctors look for a near-perfect ‘10 out of 10’ match to ensure the transplanted cells are accepted by the patient’s body. However, only about 30% of patients find such a match within their family, leaving nearly 70% dependent on unrelated donors registered in donor databases.
This is where India faces a stark gap. While countries like Germany and the United States have millions of registered donors, only about 0.09% of India’s eligible population is registered as a blood stem cell donors. As a result, many patients have to rely on international registries, a process that is not only expensive but also emotionally and logistically overwhelming for families already battling life-threatening illnesses, he pointed out.
Delays in finding a matching donor can be fatal, as diseases such as leukaemia and aplastic anaemia can progress rapidly, reducing the window in which a stem cell transplant can be lifesaving. For children with disorders such as thalassemia major or sickle cell disease, the lack of donor availability leads to prolonged suffering, repeated transfusions and irreversible organ damage, said Paul.
For families anxiously waiting for a matching donor, strengthening, India’s blood stem cell donor registry represents more than a healthcare priority. It offers hope for survival. Increasing donor registrations through sustained awareness campaigns, myth busting initiatives, and community engagement can dramatically change results. The answer to building a robust and representative donor pool is by encouraging participation across metros, smaller cities, educational institutions, workplaces, and healthcare settings, he said.
With greater awareness and collective action, India has the potential to create meaningful change in stem cell donor participation across the country. Every new donor added to the registry brings hope to patients waiting for a second chance at life. Strengthening the donor registry today will directly translate into better survival rates, reduced dependence on international systems, and, most importantly, renewed hope for thousands of families across the country, said Paul. |
