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. Of these, four were unable to comply with the diet and withdrew, two completed the study, and one was withdrawn due to a dose limiting toxicity.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 Of these, one completed the study and the other was withdrawn due to a dose limiting toxicity.
Based on promising preclinical data, ketogenic diets KDs have been proposed as supplementary measures for cancer patients undergoing standard-of-care therapy. Subjects met with a Registered Dietitian and kitchen staff prior to beginning the clinical trial to discuss their food preferences and sample the diet. For the purpose of these studies, adverse events were defined and graded utilizing the Common Terminology Criteria for Adverse Events v. 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. Cancer Res. None of the subjects developed ketoacidosis. Once the tumour has spread to distant sites metastases surgery is mostly palliative Radiation therapy — For all the advances radiation cannot differentiate between cancer and normal cells and will destroy all cells in their path.

Ketogenic diets KD are high in fat and low in carbohydrate 7 and are currently used clinically as an alternative therapy for childhood epilepsy 8.

|Radiation on treatment diet keto think that||Based on promising preclinical data, ketogenic diets KDs have been proposed as supplementary measures for cancer patients undergoing standard-of-care therapy. However, data is still scarce on the tolerability and effects of KDs on cancer patients undergoing radiotherapy RT. Here we present six cases of patients who underwent RT and concurrently consumed a self-administered KD in our clinic within a busy community hospital setting. All patients were followed prospectively with measurements of blood parameters, quality of life and body weight and composition using bioelectrical impedance analysis.|
