Feasibility and Yield of Screening in Relatives From Familial Pancreatic Cancer Families

Abstract

This study, we investigate whether screening at-risk relatives of familial pancreatic cancer (FPC) patients is safe and has significant yield. METHODS: We enrolled 309 asymptomatic at-risk relatives into our Familial Pancreatic Tumor Registry (FPTR) and offered them screening with magnetic resonance cholangiopancreaticogram (MRCP) followed by endoscopic ultrasound (EUS) with fine needle aspiration if indicated. Relatives with findings were referred for surgical evaluation. RESULTS: As of 1 August 2009, 109 relatives had completed at least one cycle of screening. Abnormal radiographic findings were present on initial screening in 18/109 patients (16.5%), 15 of whom underwent EUS. A significant abnormality was confirmed in 9 of 15 patients, 6 of whom ultimately had surgery for an overall diagnostic yield of 8.3% (9/109). Yield was greatest in relatives >65 years old (35%, 6/17) when compared with relatives 55–65 years (3%, 1/31) and relatives 65 years of age, confirming prior studies. MRCP as initial screening modality is safe and effective....
