Detection of recurrent colorectal carcinoma by 18F-FDG: comparison of the clinical performances of FDG PET and FDG CDET

Abstract

For detection of recurrent colorectal carcinoma, a 2-D coincidence gamma camera with 19 mm thick crystals and optimized acquisition and reconstruction parameters provides similar results in terms of accuracy, both per patient and per site, to those of an Nal PET camera.

Diagnostic value of FDG‐PET in recurrent colorectal carcinoma: A meta‐analysis

“…Because our criteria for assessing quality were stringent, no study met all of them. Three studies satisfied over 90% of the criteria,11, 14, 32 5 studies satisfied 80% to 89% of the criteria,8, 26, 28, 30, 31 4 studies satisfied 70% to 79% of the criteria,9, 10, 29, 33 7 studies satisfied 60% to 69% of the criteria,12, 13, 20, 22–25 4 studies satisfied 50% to 59% of the criteria18, 19, 21, 27 and 4 studies met less than 50% of the criteria 7, 15–17. In general, studies adequately described their technical methods and followed most of the guidelines published by the Society of Nuclear Medicine for performing FDG‐PET imaging.…”

“…A total of 300 articles in English‐language were initially retrieved from PubMed. Thirty‐one articles were considered as candidates after the perusal of titles and abstracts 7–33, 35–38. Four articles were excluded due to using PET/CT 35–38.…”

“…The mean age of participants ranged from 55 to 68.4 years, and 44% to 77% of participants were men. Of these studies, 16 studies reported results by hepatic metastasis using as the unit of analysis,7, 11–13, 15, 16, 18, 19, 23, 25–29, 31, 33 14 studies by pelvic metastasis or local regional recurrence7, 8, 11–13, 15, 16, 18, 19, 23, 25, 27, 30, 31 and 19 studies by distant metastasis or whole body involvement 9–17, 19–27, 32…”

Tomographie par émission de positons et cancers digestifs

“…Deux sites dé licats : les mé tastases pulmonaires où la TDM a une grande sensibilité mê me pour de petites lé sions sans pouvoir les caracté riser, et la carcinose pé ritoné ale où la TEP a de meilleures performances que les autres mé thodes d'imagerie mais est prise en dé faut lorsqu'il n'existe qu'une infiltration de faible é paisseur ou des lé sions secondaires dissé miné es de petite taille. Nous avons retrouvé des valeurs trè s similaires sur 473 examens TEP au FDG é valuables effectué s à Tenon[62], avec une excellente valeur pré -dictive positive de 97 % au niveau patient qui place la TEP au premier rang aprè s les examens de base (é chographie hé patique) en cas de suspicion de ré cidive. La valeur pré dictive né gative est moins é levé e (72 % au niveau patient) et d'autres examens doivent ê tre effectué s en cas de né gativité de la TEP au FDG et forte probabilité de ré cidive.Restadification d'une ré cidive authentifié e avant ré section à visé e curative Le contexte le plus fré quent est la dé termination de l'opé rabilité et du caractè re isolé de mé tastases hé patiques.…”
