Bone loss and hematological malignancies in adults: a pilot study

Area of Science:

• Hematology
• Oncology
• Bone Metabolism

Background:

• Bone loss, including osteopenia and osteoporosis, is a known complication of solid tumors and hematological malignancies, particularly in children.
• Research on the skeletal impact of adult hematological malignancies is limited, highlighting a gap in understanding these adverse effects.

Purpose of the Study:

• To identify hematological diseases in adults associated with the highest prevalence and severity of osteoporosis.
• To investigate the relationship between specific hematological diagnoses and bone mineral density.

Main Methods:

• Dual-energy X-ray absorptiometry (DXA) was used to assess bone mineral density in 181 adult patients with hematological neoplasms (excluding multiple myeloma).
• Patient data included DXA T and Z scores, diagnosis, and predisposing factors for osteoporosis, supplemented by hospital chart reviews.

Main Results:

• 65% of patients exhibited bone loss (38% osteopenia, 27% osteoporosis).
• Abnormal DXA Z scores (< -2.0) were found in 11.4% of patients, significantly higher than the expected 2.5%.
• Bone loss prevalence varied by diagnosis: 49% in chronic lymphocytic leukemia/small lymphocytic lymphoma, 67% in non-Hodgkin lymphoma, and 88% in Hodgkin disease.

Conclusions:

• Adults with hematological malignancies face substantial bone loss compared to the general population.
• The specific hematological diagnosis is a more critical predictor of bone loss risk than the time elapsed since diagnosis.
• Proactive measures, including lifestyle changes and prophylactic treatments, are recommended for patients undergoing or completing therapy for hematological malignancies.
