5-aminolevulinic acid for quantitative seek-and-treat of high-grade dysplasia in Barrett’s esophagus cellular models

High-grade dysplasia (HGD) in Barrett’s esophagus (BE) poses increased risk for developing esophageal adenocarcinoma. To date, early detection and treatment of HGD regions are still challenging due to the sampling error from tissue biopsy and relocation error during the treatment after histopathological analysis. In this study, CP-A (metaplasia) and CP-B (HGD) cell lines were used to investigate the “seek-and-treat” potential using …
