Fig. 1From: Impact of 68Ga-PSMA PET/CT on salvage radiotherapy planning in patients with prostate cancer and persisting PSA values or biochemical relapse after prostatectomyA 74-year-old patient with biochemical recurrence (PSA 0.82Â ng/ml; pT2aN0cM0; Gleason 6; iPSA 5.37Â ng/ml) 8.4Â months after radical prostatectomy and lymph node dissection. 68Ga-PSMA PET/CT prior to salvage radiotherapy showed two PSMA-positive presacral (a, c) and retroperitoneal (b, d) LNMs. Salvage radiotherapy was extended to pelvic lymph nodes, including a dose escalation to the PSMA-positive lymph nodes. The patient was treated with IMRT (c, d IMRT plan). red PTV including pelvic lymph nodes (50.4Â Gy), blue simultaneous and sequential boost (66Â Gy) for iliac (d) and presacral (c) LNM. RT to prostate bed is not shown. The PSA level decreased to 0.02Â ng/ml after SRTBack to article page
