The role of radiotherapy after radical prostatectomy

To the Editor We have read with great interest and enjoyed Dr Özkanlı et al.’s well designed and well written research paper entitled “Gleason score at the margin can predict biochemical recurrence after radical prostatectomy, in addition to preoperative PSA and surgical margin status” in a recent issue of the journal (2014; 44 (3): 397–402) (1). However, we have some questions about the study. As we understand, 94 patients were included in your study and these patients were with pathologic stage T2 and T3 and 34 patients (36.2%) had positive surgical margins (PSMs).
