However, the best imaging technique for early detection of pNETs in VHL is currently unknown. In a head-to-head comparison, we evaluated endoscopic ultrasound (EUS) and <jats:sup>11<\/jats:sup>C-5-hydroxytryptophan positron emission tomography (<jats:sup>11<\/jats:sup>C-5-HTP PET) compared with conventional screening techniques for early detection of pancreatic solid lesions in VHL patients.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>We conducted a cross-sectional, prospective study in 22 patients at a tertiary care university medical center. Patients with VHL mutation or with one VHL manifestation and a mutation carrier as first-degree family member, with recent screening by abdominal computed tomography (CT) or magnetic resonance imaging (MRI) and somatostatin receptor scintigraphy (SRS), were eligible. Patients underwent EUS by linear Pentax echoendoscope and Hitachi EUB-525, and <jats:sup>11<\/jats:sup>C-5-HTP PET. Patient-based and lesion-based positivity for pancreatic solid lesions were calculated for all imaging techniques with a composite reference standard.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>In 10 of the 22 patients, 20 pancreatic solid lesions were detected: 17 with EUS (<jats:italic>P <\/jats:italic> &lt; 0.05 vs CT\/MRI+ SRS), 3 with <jats:sup>11<\/jats:sup>C-5-HTP PET, 3 with SRS, 9 with CT\/MRI, and 9 with CT\/MRI + SRS. EUS evaluations showed solid lesions with a median size of 9.7 mm (range 2.9\u201355 mm) and most of them were homogeneous, hypoechoic, isoelastic, and hypervascular. Moreover, EUS detected multiple pancreatic cysts in 18 patients with a median of 4 cysts (range 1\u201330).<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>EUS is superior to CT\/MRI + SRS for detecting pancreatic solid lesions in VHL disease.<jats:sup>11<\/jats:sup>C-5-HTP PET has no value as a screening method in this setting.
