Myelofibrosis is a type of cancer that affects the bone marrow's ability to generate new blood cells due to the accumulation of scar tissue within the marrow. This poses significant challenges in treatment, often necessitating bone marrow transplantation.
However, the decision-making process for identifying suitable candidates for transplant involves patient factors such as age, disease stage, comorbidities, performance status, and donor availability. To aid in this complex assessment, the Myelofibrosis Transplant Scoring System (MTSS) and CIBMTR/EBMT score have emerged as valuable tools.
Recently, a study by the Chronic Malignancies Working Party (CWMP) of the EBMT delved into the impact of comorbidities and body mass index (BMI) on transplant outcomes in myelofibrosis.
The BMI or body mass index is a calculation that comes from a person’s height and weight to determine underweight, normal, overweight or obesity.
With 4,086 enrolled patients, the study provided important insights into the intricate relationship between patient characteristics and transplant success.
BMI could reflect a patient’s nutritional status and overall health. Understanding the impact of other diseases like diabetes, hypertension, or pre-existing conditions on myelofibrosis and BMI has been crucial for offering a transplant as a curative treatment for eligible patients.
A total of 2679 patients had information on BMI at the time of transplant:
The high prevalence of overweight and obese individuals suggested that patients with more adipose tissue or higher nutritional reserves were more often considered suitable for transplantation. In contrast, underweight or low-muscle index patients may have had their transplants deferred due to the association with a worse transplant course.
In the patients’ outcomes, BMI was weakly correlated with all other comorbidities (aside from diabetes). The results showed that despite BMI, there was no significant difference in survival after transplantation across any BMI subgroup.
Before this study results, offering a transplant to patients with a BMI over 35 (obesity of third degree or over) was mostly avoided since it was considered a risk factor in both non-relapse mortality and overall survival after transplantation.
In this context, it seems that overweight and obese myelofibrosis patients should not be excluded from a potentially curative life-saving procedure like bone marrow transplant. On the other hand, even patients with lower BMIs can derive benefits from a transplant procedure.
In myelofibrosis, overweight or obesity can be associated with milder disease activity, resulting in better nutritional status and suggesting a greater likelihood of improved survival.
It is very important to continue active research on myelofibrosis patients so that their progression can be prevented one day. If you want to stay updated with the advances in myelofibrosis treatment, join our newsletter!
