The 99mTc-MIP-1404 PSMA Uptake in the Isolated Paratracheal Lymph Node From the Prostate Adenocarcinoma

Abstract

The oncologist consulted a 56-year-old man after receiving prostate-specific antigen screening results. Prostate-specific antigen level during the screen time was 33 ng/mL. As a result, poorly differentiated prostate adenocarcinoma with a Gleason score of 9 (5 + 4) was diagnosed. SPECT/CT scan with 99m Tc-MIP-1404 PSMA tracer was performed. The 99m Tc-PSMA–positive lesions were detected in the prostate, external iliac, obturator lymph nodes of the pelvis, para-aortic, and the right lower paratracheal space. The patient was prescribed androgen deprivation therapy and early chemotherapy with docetaxel (6 fractions), after which radiation therapy to prostate and seminal vesicles was planned.
