KLK3 and pachyonychia congenita: Against the background of lower pre-RT PSA levels compared to previous studies that investigated the sensitivity of DCE-MRI with EC in the detection of PC recurrence (PSA, averaged 0.8 - 1.26 ng/mL), the sensitivity of 67% reported in this study appears to be comparable to the performance of DCE-MRI with EC (sensitivity, 71 – 88%)[7,8,18].
