Patients with CF at increased risk for GI cancers

The emergence of gastrointestinal cancer as a clinical complication in adults with cystic fibrosis is a consequence of the substantial improvement in life expectancy. Novel CFTR modulator therapies, which correct the malfunctioning protein and increase its expression at the apical surface, might decrease the incidence of gastrointestinal cancers in patients with cystic fibrosis.

In conclusion, the meta-analysis by Yamada and colleagues shows that cystic fibrosis can be considered a gastrointestinal cancer syndrome, for which screening and surveillance protocols should be implemented. Oncologists and gastroenterologists managing patients with cystic fibrosis should consider the best methods for screening of the small bowel, biliary tract, pancreas, and colon to prevent gastrointestinal malignancies in these patients.
