Abstract

A 75-year-old man with evidence of recurrent prostate cancer on 68Ga-prostate-specific membrane antigen (PSMA) PET/CT after radical prostatectomy was referred to our department for 99mTc-PSMA radioguided surgery. Intraoperatively, lymph nodes with high count rates were localized using a handheld gamma probe. High-count specimens were resected from the exact locations as reported by 68Ga-PSMA PET/CT. The total prostate-specific antigen value decreased 6 weeks after surgery. Our case shows the feasibility of radioguided surgery with 99mTc-PSMA for salvage lymphadenectomy in prostate cancer.
