Abstract
To evaluate the quality and quantity of the bone marrow aspirates and biopsy specimens obtained with a powered system in comparison with the standard manual method.
The Pathology Laboratory Information System was reviewed for patients who had previously undergone bone marrow biopsies performed by both the OnControl Bone Marrow System and the manual method. A total of 136 cases (68 patients) were reviewed for adequacy and compared using an unpaired t test.
The core biopsy specimens obtained by the OnControl system were significantly longer compared with those obtained by the manual system (16.9 vs 14.4 mm, P = .0036). However, the core biopsy specimens obtained by the manual method had on average more evaluable marrow elements (66% vs 40%, P < .0001), and the manual method was superior in 46 of the 68 cases when the length of evaluable marrow was calculated (9.7 vs 7 mm, P = .0049).
Our findings show that longer core biopsy specimens are obtained by the OnControl Bone Marrow system but that the manual method is still superior when the percentage and length of evaluable bone marrow are analyzed.
