From: Differential response of esophageal cancer cells to particle irradiation
Esophageal cancer cell lines show heterogeneous survival after photon and particle irradiation. Clonogenic survival curves of OE19 and OE33 adenocarcinoma and KYSE270 and KYSE410 squamous cell carcinoma cell lines after photon (X), proton (1H), carbon ion (12C) and oxygen ion (16O) irradiation (mean ± SD of 3 independent experiments). The table depicts the relative biological effectiveness (RBE) for 1H, 12C and 16O radiation at 10% survival
