The rate of positive surgical margins (PSM) was compared between anticipated HR cancer according to D'Amico risk classification and discovered postoperative HR cancer.
MATERIALS AND METHODS: A retrospective study was conducted between 2006 and 2013 on patients who underwent RARP. Before surgery, patients were divided according to the D'Amico risk classification. After surgery, HR was defined as pT3a or pT3b, or Gleason score≥8 or positive lymph nodes. The rate of PSM was compared according to the D'Amico risk classification and postoperative HR.
RESULTS: During the study, 485 patients were reviewed. Before surgery, 10 % of cancers were classified as D'Amico 3 (49/485). After surgery, 27.6 % (134/485) were classified as HR. There was a significant difference between the rate of PSM in HR/D'Amico 3 and HR/non D'Amico 3 cancer, respectively 22.9 % and 34.3 % (P< 0.001).
CONCLUSION: The RARP is feasible in HR with an average of 30 % of PSM as in open surgery. However, the accurate assessment of preoperative HR will allow a more adapted dissection and a decrease of rate of PSM. So it is necessary to improve the detection of HR and so to select the most suitable cancer for surgery.
