Aspiration does not influence interpretation of bone marrow biopsy cellularity
Abstract:
Alterations of hematopoietic cellularity have been described in preaspirated marrow biopsy specimens. In this study, the extent of aspiration-induced artifacts was evaluated by comparing preaspirated and nonaspirated marrow biopsy specimens obtained from individual patients. Fourteen patients (28 specimens) were studied. One specimen, containing only cortical bone, was not evaluable. Of the remaining specimens, estimation of hematopoietic cellularity was not disturbed by preaspiration. Provided an adequate sized biopsy specimen is obtained, this study demonstrates that aspiration can be performed immediately before biopsy without altering the interpretation of hematopoietic cellularity. This makes a simple one-step aspiration-biopsy technic possible, without loss in diagnostic accuracy. In addition, without the need for repositioning to a different site on the iliac crest, patient tolerance should be improved.
Insights
Preaspirating bone marrow biopsy specimens does not alter hematopoietic cellularity. This finding supports a simplified one-step aspiration-biopsy technique, improving diagnostic accuracy and patient comfort.
Area of Science:
- Hematology
- Pathology
- Medical Procedures
Background:
- Hematopoietic cellularity in bone marrow biopsy specimens has been previously linked to preaspiration alterations.
- Evaluating aspiration-induced artifacts is crucial for accurate diagnostic interpretation of bone marrow biopsies.
Purpose of the Study:
- To assess the impact of preaspiration on the evaluation of hematopoietic cellularity in bone marrow biopsy specimens.
- To determine if a one-step aspiration-biopsy technique can be safely implemented without compromising diagnostic accuracy.
Main Methods:
- Comparison of preaspirated and nonaspirated bone marrow biopsy specimens from 14 individual patients (28 specimens total).
- Evaluation of hematopoietic cellularity estimation in relation to preaspiration.
Main Results:
- Estimation of hematopoietic cellularity was not significantly disturbed by preaspiration in evaluable specimens.
- Adequate-sized biopsy specimens obtained after preaspiration maintained diagnostic interpretability.
Conclusions:
- Preaspiration immediately before bone marrow biopsy does not alter the interpretation of hematopoietic cellularity.
- A simplified one-step aspiration-biopsy technique is feasible, maintaining diagnostic accuracy and potentially improving patient tolerance.
