“…Although choline-based PET is characterized by a relatively low sensitivity in patients with prostate-specific antigen (PSA) values <1 ng/ml, 11 C-choline-PET is useful in evaluating disease recurrence, with detection rates ranging from 21 to 82%, particularly when PSA values are >2 ng/ml. Nonetheless, radiolabeled choline is not completely cancer-specific due to uptake in areas with benign inflammation (49, 50). Although choline tracers provide good detection rates in PCa, particularly for local recurrences, they seem to be less specific for nodal and bone metastases because of potential uptake artifacts caused by inflammatory reactions and degenerative bone disease (51, 52).…”

“…Al estudiar el desempeño de la PETC en la RCP con valores de PSA <1 ng/ml, Gómez de la Fuente y col. 28 no encontraron significancia estadística respecto al PSADT y PSAV en la detección de RCP con una PETC en ningún grupo de pacientes. No obstante, Mamede y col. 29 evaluaron la performance de la PETC en pacientes con RCP temprana con valores de PSA <0,5 ng/ml y constató que la PETC fue positiva en el 38% de los pacientes con un PSADT <6,23 meses; contra el 3% en los pacientes con un PSADT >6,23 meses, siendo este hallazgo estadísticamente significativo en el análisis multivariado.…”
