Intraoperative bone marrow puncture in breast cancer patients: Prospective assessment of adverse side-effects

Abstract Background and aim In breast cancer patients, intraoperative bone marrow puncture (BMP) with positive detection of disseminated tumor cells has been reported to predict unfavorable clinical outcome due to increased risk of recurrence. In this study, we prospectively assessed BMP-associated untoward side-effects. Methods Fifty-eight consecutive breast cancer patients were prospectively explored after intraoperative BMP for postoperative pain (visual analogue scale, VAS) and complications in terms of infection, hematoma, and sensibility disorder. Furthermore, the impact of BMP on hospital stay duration was analyzed in 254 patients. Results In all subgroups analyzed, during five postoperative days patients complained about minor pain only at the site of BMP (VAS  p  = 0.04), less frequently smokers ( p  = 0.02), and presented with higher body mass index ( p  = 0.01) than controls. Within the area of BMP no signs of infection or sensibility disorders were observed. Comparison of patients with and without BMP did not show any significant difference in postoperative hospital stay duration. Conclusion Referring to the potential clinical benefit of intraoperative BMP its prospectively assessed adverse side-effects appear relatively mild and thus acceptable.
