There are studies that suggest a negative influence of hormone therapy on the sensitivity of choline PET/CT,<a class="elsevierStyleCrossRefs" href="#bib0225"><span class="elsevierStyleSup">15,22,24</span></a> while other studies show that it does not influence the sensitivity of the exploration.<a class="elsevierStyleCrossRefs" href="#bib0280"><span class="elsevierStyleSup">26,29</span></a></p><p id="par0135" class="elsevierStylePara elsevierViewall">Several preclinical studies have evaluated the effect of antiandrogen treatments on choline uptake. Hara et al.<a class="elsevierStyleCrossRef" href="#bib0300"><span class="elsevierStyleSup">30</span></a> investigated the effect of androgens on choline absorption in androgen-dependent and androgen-independent cells. The depletion of androgens led to a marked decrease in choline absorption in the androgen-sensitive cells, but not in the androgen-resistant cells. In a retrospective study of a small group of 14 patients with BR of PC, Fuccio et al.,<a class="elsevierStyleCrossRef" href="#bib0225"><span class="elsevierStyleSup">15</span></a> performed a 11C-choline PET/CT study before initiating antiandrogen therapy (mean PSA, 17.0<span class="elsevierStyleHsp" style=""></span>ng/ml) and six months after administration of the therapy (mean PSA, 2.4<span class="elsevierStyleHsp" style=""></span>ng/ml), and found a significant reduction of 11C-choline uptake in patients with hormone-sensitive PC, thus suggesting that they are withdrawn before performing the exploration in order to avoid possible false negative results. These studies distinguish between patients with hormone-sensitive and hormone-resistant PC and demonstrate a possible inhibitory effect of HT on choline uptake in these hormone-sensitive patients. The fact that HT decreases the detection rate and/or the SUVmax of the choline PET/CT study in androgen-sensitive patients is predictable: this is a consequence of the effect of antiandrogen therapy. However, the influence of HT in hormone-resistant patients continues to be a controversial issue.</p><p id="par0140" class="elsevierStylePara elsevierViewall">Our work includes patients who had been treated with curative intent (using RP, EBRT or BT) and other patients who, perhaps because of their high initial risk, were treated with HT at baseline.

The FCH PET/CT detection rate in the CR group was 89.1%, significantly higher than the group treated with radical intention (with or without adjuvant hormonal therapy), which was 29.9%, <span class="elsevierStyleItalic">p</span><span class="elsevierStyleHsp" style=""></span><<span class="elsevierStyleHsp" style=""></span>0.001.

Another limitation of the study is that the absence of agreed criteria when requesting the FCH PET/CT exploration from the urologist or radiation oncologist may have produced a selection bias. It is also worth noting that the importance of other treatments such as bisphosphonates, and the different types of hormone therapy administered and their initiation times, are not clear. The main limitation of our study is the lack of a gold histological standard with which to compare test results as well as having to resort to different clinical validation criteria, which may have overestimated or underestimated the true number of positive explorations. However, it should be remembered that this limitation is common to most of these types of studies, given the ethical and logistical considerations involved in biopsy lesions in these patients.</p><p id="par0155" class="elsevierStylePara elsevierViewall">In conclusion, FCH-PET/CT is useful in detecting the disease in BR of PC.
