ObjetivoEstudiar el impacto clínico en el manejo de los pacientes de la 18F-fluorocolina (18F-COL) en la recurrencia de neoplasias cerebrales primarias.Material y métodosSe estudió prospectivamente a 21 pacientes con sospecha de recidiva de neoplasia cerebral primaria mediante PET/TC cerebral con 18F-COL en uso compasivo. La distribución por patología de los pacientes estudiados fue: 3 astrocitomas grado ii, 3 astrocitomas grado iii, un oligodendroglioma grado ii, 3 oligodendrogliomas grado iii, un oligoastrocitoma grado iii, 4 glioblastomas multiformes, una gliomatosis cerebri y 5 meningiomas. Se consideraron positivos los estudios en los que había una captación visualmente significativa respecto al fondo del parénquima cerebral.ResultadosDiecisiete de los pacientes fueron positivos, comprobándose dicho resultado por histología (10 de ellos) o seguimiento clínico y por neuroimagen, sin hallarse falsos positivos o negativos. El índice target to backgroud ratio medio para los positivos fue de 8,02 y para los negativos de 0,94, lo que representa una diferencia significativa (p=0,003).ConclusiónLa PET/TC con 18F-COL presenta resultados alentadores en la valoración de pacientes con sospecha de recidiva.AimTo study the usefulness of 18F-fluorocholine (FCH) in detecting the recurrence of primary brain tumours.Material and methodsA prospective study was conducted on brain PET/CT with FCH for compassionate use in 21 patients with suspected recurrence of a primary brain tumour. The distribution by pathology was: three grade ii astrocytomas, three grade iii astrocytomas, one grade ii oligodendroglioma, three grade iii oligodendrogliomas, one grade iii oligoastrocytoma, four glioblastoma multiform, one gliomatosis cerebri, and five meningiomas. Studies in which there was a visually significant uptake in the brain parenchyma were classified as positive.ResultsA total of 17 patients were classified as positive, with the results being confirmed by histology (10 cases) or clinical follow-up and imaging, with no false positives or negatives. The mean SUVmax for positive patients was 8.02 and 0.94 for the negative ones, which was significantly different (P=.003)ConclusionPET/CT with FCH shows encouraging results in the evaluation of patients with suspected recurrence of primary brain neoplasms.
