Abstract

Context: Choline positron emission tomography (PET)/computed tomography (CT) is a currently used diagnostic tool in restaging prostate cancer (PCa) patients with increasing prostate-specific antigen (PSA) after either radical prostatectomy (RP) or external-beam radiation therapy (EBRT). However, no final recommendations have been made on the use of this modality for patient management.

Objective: To critically analyse the current evidence for the use of choline PET/CT scanning in the management of patients with a progressive increase in PSA after radical treatment for PCa, evaluating its diagnostic accuracy in the detection of recurrences, the clinical predictors of positive PET/CT examinations, and the modalities' role as a guide for tailored therapeutic strategies.

Evidence acquisition: Data on recently published (2003-2010) original articles, review articles, and editorials concerning the role of choline PET/CT in this scenario were analysed.

Evidence synthesis: The diagnostic accuracy of choline PET in detecting sites of PCa relapse has been investigated by several authors, and the overall reported sensitivity ranges between 38% and 98%. It has been demonstrated that choline PET technology's positive detection rate improves with increasing PSA values. The routine use of choline PET/CT cannot be recommended for PSA values <1 ng/ml. However, in addition to PSA serum value, PSA doubling time (PSA DT), and other clinical and pathologic features-including locally advanced tumour (pT3b-T4) or lymph node involvement at initial staging-should be considered to refer patients to choline PET/CT study. Choline PET/CT may be also proposed as a image guide either for experimental surgical or radiation therapy treatments.

Conclusions: According to the current available data, choline PET/CT plays a role in the management of biochemical relapse. Its accuracy is correlated to PSA value, PSA DT, and other pathologic features. Choline PET/CT may be proposed as a guide for individualised treatment of recurrence.
