Abstract

The omentum is a rare metastatic site for prostatic adenocarcinoma. We present a case of metastatic castrate-resistant prostate cancer, with progressive omentum invasive prostate cancer identified on prostate-specific membrane antigen (PSMA) PET/CT scan. Omental biopsy revealed metastatic prostate adenocarcinoma, and cabazitaxel chemotherapy was instituted with a prostate-specific antigen biochemical response. Repeat PSMA PET/CT imaging revealed increased avidity in omental metastasis. Despite prostate-specific antigen response, PSMA PET/CT did not correlate with a therapeutic response.

摘要

网膜是前列腺腺癌罕见的转移部位。我们报告一例转移性去势抵抗性前列腺癌，前列腺特异性膜抗原（PSMA）PET/CT 扫描显示进行性网膜侵袭性前列腺癌。网膜活检显示转移性前列腺腺癌，给予卡巴他赛化疗，前列腺特异性抗原生化反应得到改善。重复 PSMA PET/CT 成像显示网膜转移灶摄取增加。尽管前列腺特异性抗原有反应，但 PSMA PET/CT 与治疗反应无相关性。
