The detection of gastrointestinal (GI) involvement in Mantle Cell Lymphoma is often underestimated and may have an impact on outcome and clinical management. We aimed to evaluate whether baseline 18F-FDG PET/CT presents comparable results to endoscopic biopsy in the diagnosis of GI localizations. In our retrospective cohort of 79 patients, sensitivity and specificity of 18F-FDG PET/CT were low for the stomach, with a fair concordance ( = 0.32), while higher concordance with pathologic results ( = 0.65) was detected in the colorectal tract. Thus, gastric biopsy remains helpful in the staging of MCL despite 18F-FDG PET/CT, while colonoscopy could be omitted in asymptomatic patients. The validation of our data in prospective cohorts is desirable.
套细胞淋巴瘤胃肠道受累的检测常常被低估，可能会对预后和临床管理产生影响。我们旨在评估基线18F-FDG PET/CT在胃肠道定位诊断中是否与内镜活检结果相当。在我们79例患者的回顾性队列中，18F-FDG PET/CT对胃的敏感性和特异性较低，一致性一般（κ = 0.32），而在结直肠部位与病理结果的一致性较高（κ = 0.65）。因此，尽管有18F-FDG PET/CT，胃活检对于套细胞淋巴瘤的分期仍有帮助，而对于无症状患者可以省略结肠镜检查。在未来前瞻性队列中验证我们的数据是很有必要的。
