Current evaluation of the clinical utility of Fluoromethylcholine-(18F) PET/CT in Prostate Cancer

摘要

This short review is dedicated to the current status of the assessment of a new PET radiopharmaceutical, fluoromethylcholine-(18F) or FCH, which is taken-up by prostate cancer tissue, in contrary to fluorodeoxyglucose-(18F) or FDG. It seems that FCH could become "the FDG of prostate cancer", with the same type of achievements (detection of distant metastases and of occult recurrences, restaging prior to invasive treatments), and the same drawbacks (false negative results in case of small lesions, in particular lymph nodes metastases, and false positive results in case of infection/inflammation, in particular prostatitis). Current evidence is summarised and discussed for each of the potential settings of FCH PET/CT imaging in prostate cancer. The perspectives for granting a marketing authorisation to a FCH preparation are briefly analysed.
