BACKGROUND:Blood management strategies help to conserve allogeneic red blood cells, a finite resource.
Intraoperative cell salvage (ICS) is an effective method of allogeneic avoidance. However, concerns persist about the safety of ICS in surgical oncology cases, including radical prostatectomy (RP). Previous findings do not support these concerns. We hypothesized that ICS would not increase rates of long-term prostate cancer recurrence characterized by biochemical failure, disease dissemination, or mortality.
STUDY DESIGN AND METHODS: Consecutive patients undergoing RP by a single urologist over two 3-month periods 1 year apart were analyzed retrospectively. Patients in the first period had preoperative autologous donation (PAD) but not ICS (PAD group), whereas those in the second period had ICS only (ICS group). Variables assessed included patient demographics, prostate-specific antigen levels at surgery and end of follow-up, clinical stage, operative time, surgical margin status, pathologic stage and grade, Gleason score sum, length of hospital stay, biochemical recurrence, metastases, and mortality.
RESULTS: A total of 116 consecutive patients were analyzed. Of these, 32 patients in the PAD group and 42 patients in the ICS group had follow-up of at least 4.75 years. There was a significantly higher rate of biochemical failure (34.4% vs. 9.5%; p = 0.02) and metastases (12.5% vs. 0%; p = 0.03) in the PAD group versus the ICS group; there was no significant difference in mortality (9.4% vs. 0%; p = 0.08).
CONCLUSION: ICS appears to be a safe and effective method of allogeneic blood conservation in patients undergoing RP. The findings suggest that there is no increased risk of biochemical failure, disease dissemination, or mortality at 5 years post-RP as a result of ICS use.
