title: [Case of persistent false elevation of prostate-specific antigen after radical prostatectomy].
abstract: We report a rare case of persistent false elevation of prostate-specific antigen (PSA) after radical prostatectomy (RP). Preoperative total PSA was 25.4 ng/ml and final pathology was Gleason score 3+5=8, pT3aN0M0. His first postoperative total PSA was 3.85 ng/ml. He received adjuvant hormone therapy for 10 months. Since PSA gradually elevated despite adjuvant hormone therapy, he underwent imaging for metastasis, confirming no evidence of prostate cancer recurrence. Moreover, total PSA was unmeasurable level in three other PSA assays.
