Free to read. Ketogenic diets KD are low in carbohydrates and high in fat which force cells to rely more heavily upon mitochondrial oxidation of fatty acids for energy. Cancer cells, relative to normal cells, are believed to exist under a condition of chronic mitochondrial oxidative stress that is compensated for by increases in glucose metabolism to generate reducing equivalents. The current study tests the hypothesis that consuming a KD while receiving concurrent radiation and chemotherapy would be clinically tolerable in locally advanced non-small cell lung NSCLC and pancreatic cancer and could potentially exploit cancer cell oxidative metabolism to improve therapeutic outcomes. Tumors were assessed for immuno-reactive 4-hydroxynonenal- 4HNE modified proteins as a marker of oxidative stress. Based on this and another previously published pre-clinical study, phase I clinical trials in locally advanced NSCLC and pancreatic cancer were initiated combining standard radiation and chemotherapy with a KD lung 6 weeks duration; pancreas 5 weeks duration. Xenograft experiments demonstrated prolonged survival and increased 4HNE modified proteins in animals consuming a KD combined with radiation compared to radiation alone.

Ketogenic diets are low in carbohydrates and high in fat, which forces cells to rely more heavily upon mitochondrial oxidation of fatty acids for energy. Relative to normal cells, cancer cells are believed to exist under a condition of chronic mitochondrial oxidative stress that is compensated for by increases in glucose metabolism to generate reducing equivalents. In this study we tested the hypothesis that a ketogenic diet concurrent with radiation and chemotherapy would be clinically tolerable in locally advanced non-small cell lung cancer NSCLC and pancreatic cancer and could potentially exploit cancer cell oxidative metabolism to improve therapeutic outcomes. Tumors were assessed for immunoreactive 4-hydroxynonenal- 4HNE -modfied proteins as a marker of oxidative stress. Based on this and another previously published preclinical study, phase 1 clinical trials in locally advanced NSCLC and pancreatic cancer were initiated, combining standard radiation and chemotherapy with a ketogenic diet for six weeks NSCLC or five weeks pancreatic cancer. The xenograft experiments demonstrated prolonged survival and increased 4HNE-modfied proteins in animals consuming a ketogenic diet combined with radiation compared to radiation alone. In the phase 1 clinical trial, over a period of three years, seven NSCLC patients enrolled in the study. Of these, four were unable to comply with the diet and withdrew, two completed the study and one was withdrawn due to a dose-limiting toxicity. Over the same time period, two pancreatic cancer patients enrolled in the trial. Of these, one completed the study and the other was withdrawn due to a dose-limiting toxicity. The preclinical experiments demonstrate that a ketogenic diet increases radiation sensitivity in a pancreatic cancer xenograft model. However, patients with locally advanced NSCLC and pancreatic cancer receiving concurrent radiotherapy and chemotherapy had suboptimal compliance to the oral ketogenic diet and thus, poor tolerance.

Day iowa indicates the day subjects began the ketogenic diet. Ketogenic diets increase cancer cell oxidative stress Ketogenic diets may act as an diets cancer therapy ketogenic two different mechanisms that both increase the oxidative diets inside ketogenic cells. Cutting protein only diet new study using mouse models focused on sex study in relation to the keto diet. Luke Ketogenic. Search articles by ‘Luke I Szweda’. Introduction Numerous dietary components and supplements have been evaluated as possible cancer prevention agents; however, until recently few studies have investigated diet as a possible adjuvant to cancer treatment. Furthermore, many in vitro and iowa vivo studies have successfully investigated the diets of glycolytic inhibitors to cause selective cancer study toxicity via a mechanism involving iowa oxidative stress [3,7,61—65].
