Abstract

Background: Previous studies demonstrated increased digestive tract cancers among individuals with cystic fibrosis (CF), particularly among lung transplant recipients. We describe cancer incidence among CF and non-CF lung recipients. Methods:We used data from the US transplant registry and 16 cancer registries. Standardized incidence ratios (SIRs) compared cancer incidence to the general population, and competing risk methods were used for the cumulative incidence of colorectal cancer. Results:We evaluated 10,179 lung recipients (1681 with CF). Risk was more strongly increased in CF recipients than non-CF recipients for overall cancer (SIR 9.9 vs. 2.7) and multiple cancers including colorectal cancer (24.2 vs. 1.7), esophageal cancer (56.3 vs. 1.3), and non-Hodgkin lymphoma (61.8 vs. 9.4). At five years post-transplant, colorectal cancer was diagnosed in 0.3% of CF recipients aged b50 at transplant and 6.4% aged ≥50. Conclusions: CF recipients have increased risk for colorectal cancer, suggesting a need for enhanced screening. © 2016 European Cystic Fibrosis Society. Published by Elsevier B.V.

1. Introduction

Cystic fibrosis (CF) is one of the most common life- shortening, genetic disorders and occurs in approximately one in 3500 Caucasian births in the US [1]. Mutations in the cystic fibrosis transmembrane regulator (CFTR) gene lead to malfunctioning or absent CFTR protein, which impairs mucosal clearance mechanisms causing recurring lung infec- tions, inflammation, and airflow obstruction. Over time there have been tremendous improvements in CF treatment. In 2014,
