One Mother Beat Blood Cancer Against the Odds. Thousands of Others Are Still Searching for Their Chance.

As a professional photographer and mother of two young children, Claire had always been busy, but the long hours and constant fatigue felt like an occupational hazard. She never imagined that exhaustion could signal something far more serious than a demanding schedule.

Then, in January 2024, it happened: Claire blacked out at her desk while editing videos. It was her body’s final, unmistakable warning. What followed was a hospital stay, a bone marrow biopsy, and a diagnosis that would change her life forever. Claire had been diagnosed with blood cancer, specifically Myelodysplastic Syndrome (MDS), a serious bone marrow condition that, without treatment, can be fatal.

She was just 30 years old. And she was far from alone. Blood cancer remains one of the top five causes of cancer death in South Africa. Despite being potentially curable, countless patients never find their matching donor in time. Claire was determined not to become another statistic.

A Road Full of Obstacles

Claire’s path to diagnosis was not straightforward. Doctors initially attributed her worsening symptoms to iron deficiency, leaving her untreated as her condition quietly progressed. By the time MDS was correctly identified, the only viable path forward was a stem cell transplant.

While awaiting a donor match, Claire endured bi-weekly injections to keep her body stable, a gruelling holding pattern as her family and medical team searched for hope. That hope came through DKMS Africa, which successfully identified a fully matched, unrelated donor for Claire.

The first transplant, using cells from that 100% unrelated matched donor, was performed with great hope. Unfortunately, it was not successful.

Claire’s medical team was not deterred. Turning to family, they proceeded with a haplo-identical transplant, a “half-match” procedure using stem cells donated by Claire’s brother. This second transplant was successful.

Why Every Match Still Matters

Claire’s outcome is cause for deep gratitude and genuine celebration. But her journey also carries an urgent message that must not be lost in the relief of her survival.

Haplo-identical transplants, where stem cells are donated by a family member who is only a partial genetic match rather than a full one, can offer a path forward when a fully matched donor cannot be found. However, this option is not available or ideal for everyone. Not all patients have a suitable family donor, and even when they do, the procedure carries greater medical complexity and risk than a fully matched stem cell transplant.

For most patients, a 100% match from an unrelated donor remains the gold standard: the safest and most effective option. Yet only around 30% of patients find a compatible donor within their own family, meaning the remaining 70% depend entirely on a stranger’s decision to join the registry. The more people who register as potential donors, the greater the chance that every patient in need will find their match.

The critical shortage of registered donors, particularly from diverse ethnic backgrounds, means that for many, the search ends without a match. Despite blood cancer being potentially curable, countless patients never find their matching donor in time.

Every name added to the registry is a potential lifeline for someone, somewhere, waiting for their match.

A Family Restored

Today, Claire is recovering. Her children have their mother. Her family, who stood beside her through diagnosis, uncertainty, and two transplants, now share in a renewed sense of hope and possibility.

Her story does not end with survival. It continues with a plea to every person who has considered registering as a stem cell donor and hasn’t yet done so. “Help save others like me. We need more people to register as potential stem cell donors. Your registration could mean the difference between life and death.”

Self-reported Family History Often Underestimates Relatives’ Heart Attacks

A new study from Karolinska Institutet shows that people’s own reports of heart attacks in the family only partially correspond with register data. The findings suggest that heart attacks among relatives are often underreported, particularly for events occurring early in life.

Asking patients about cardiovascular disease in the family is common practice in both research and clinical risk assessment. But how reliable is this information? Researchers at Karolinska Institutet have investigated this by comparing self-reported family history with Swedish national registers. 

The study included just over 25 000 participants from the Swedish SCAPIS cohort. Participants were asked to state whether their parents or siblings had suffered a heart attack, and the information was then compared with diagnoses in the Patient and Cause of Death Registers.

The results, published in the European Journal of Epidemiology, show that the agreement between self-reported data and register data was only moderate. 

“Our findings show that data from questionnaires only capture part of the occurrence of heart attacks in families,” says Agnes Wahrenberg, researcher at the Department of Clinical Research and Education and resident physician at Södersjukhuset. The study forms part of her doctoral thesis.

For heart attacks in close relatives, the sensitivity was 57.6 per cent, meaning that many cases identified in the registers were not reported in the questionnaires. Misreporting was more common for cases of heart attack occurring early in life.

At the same time, the study highlights the unique opportunities that Swedish health registers offer for research into hereditary cardiovascular disease.

“These registers can be used to supplement and validate family history information in both large cohorts and future register studies,” says Per Svensson, associate professor at the same department and senior physician at Södersjukhuset.

Despite these limitations, the researchers emphasise that self-reported information remains valuable, as it is easy to obtain and can help identify individuals at increased risk in everyday clinical practice.

“It can be difficult to know exactly which diseases have occurred in relatives, particularly further back in time. The Swedish registers are a unique complement to studies on family history and cardiovascular disease, as they enable a more comprehensive assessment of disease in relatives”, says Agnes Wahrenberg.
