MATERIAL & METHODS: Records of 83 patients were analysed retrospectively who had undergone a radical prostatectomy within the last five years in our clinic. The patients' age, total PSA, prostate volüme (PV), number core of cancer detected on biopsy, Gleason score, preoperative and postoperative transfusion volume, and positive surgical margins were recorded. Patients were divided into two groups by prostate size cut off at a value of 40 cc. Both groups were compared in terms of positive surgical margins. RESULTS: 83 patients were included in the study, and their mean age was 61.71±5.68, their mean PSA was 14.26±9.07 ng/mL, and their mean prostate volume was 14.83±36.82 mL. When the two groups were compared among age, total PSA, tumor detected core number, Gleason score, and transfusion volume, there was no significant difference (Table 1). When these two groups compared among positive surgical margins, there was also no significant difference (Table 2).

CONCLUSIONS: In this retrospective study, we found that there is no statistically significant relationship between prostate size and positive surgical margin. In our opinion, positive surgical margin is independent of prostate size, and it is related to surgical technique and the surgeon's experience. Eur Urol Suppl 2014; 13(7) e1509
