Presentation transcript:

The responses of H292 and A549 lung cancer xenografts to hypofractionated radiation were enhanced by the ketogenic diet. The responses of H292 and A549 lung cancer xenografts to hypofractionated radiation were enhanced by the ketogenic diet. H292 and A549 xenografts were grown in nude mice as in Fig. 2. Mice (5–9 per group) were treated with ketogenic diet for 2 days before radiation and continuing for a total of 7 days. Hypofractionated radiation (2 × 6 Gy fractions) was delivered on day 3 and 5 of the protocol. Tumor growth curves (A) and Kaplan–Meier survival plots (B) showed enhanced radiation responses in animals with H292 xenografts fed the ketogenic diet (P < 0.05), relative to ionizing radiation alone. C, tumor volume growth curve estimates of A549 xenografts also showed that ketogenic diet + ionizing radiation significantly slowed tumor growth when compared with radiation alone (P < 0.05). All treatments were well tolerated as shown by the lack of weight loss during therapy (Supplementary Figs. S1A and S1B). Bryan G. Allen et al.
