The aim of this paper is to review the role of 18F-choline or 11C-cholinePET/CT in prostate cancer patients for diagnosis, staging and restaging in case of biochemical recurrence and on the use of 18F-choline or 11C-choline PET/CT for metastases directed salvage therapies and in castrate-resistant patients treated with systemic therapy. A literature search was performed, and articles related to 11C-choline and 18F-choline PET/CT in prostate cancer staging and biochemical relapse were identified.

In lymph node and distant staging choline, PET/CT showed low sensitivity but, in most of the cases, a relatively high specificity. In case of biochemical recurrence, PSA absolute value and PSA kinetics confirmed their strict correlation with choline PET/CT findings. Choline PET/CT resulted to be very useful to address salvages therapies, especially in the early phases of biochemical recurrence. The use of choline PET/CT in CRPC should be more deeply investigated. At the moment, its use in the diagnosis of prostate cancer is not recommended. 18F-choline or 11C-choline PET/CT provides useful information to clinicians mostly in case of biochemical recurrence, while the low sensitivity limits its use during staging.

Abstract

The aim of this paper is to review the role of 18F-choline or 11C-cholinePET/CT in prostate cancer patients for diagnosis, staging and restaging in case of biochemical recurrence and on the use of 18F-choline or 11C-choline PET/CT for metastases directed salvage therapies and in castrate-resistant patients treated with systemic therapy. A literature search was performed, and articles related to 11C-choline and 18F-choline PET/CT in prostate cancer staging and biochemical relapse were identified. Search terms were: “PET” and “PET/CT”, “11C-choline”, “18F-choline”, “prostate cancer staging”, “lymph node staging” “biochemical recurrence”. We have reported the results of the most relevant publications following the criteria of clinical relevance, confirmations of choline PET/CT findings with histology, other imaging methods or clinical follow-up. Moreover, we have briefly reported about the use of 18F-choline or 11C-choline PET/CT for prostate cancer diagnosis and to monitor castrate-resistant prostate cancer (CRPC) patients treated with systemic therapy. In lymph node and distant staging choline, PET/CT showed low sensitivity but, in most of the cases, a relatively high specificity. In case of biochemical recurrence, PSA absolute value and PSA kinetics confirmed their strict correlation with choline PET/CT findings. Choline PET/CT resulted to be very useful to address salvages therapies, especially in the early phases of biochemical recurrence. The use of choline PET/CT in CRPC should be more deeply investigated. At the moment, its use in the diagnosis of prostate cancer is not recommended. 18F-choline or 11C-choline PET/CT provides useful information to clinicians mostly in case of biochemical recurrence, while the low sensitivity limits its use during staging.
