Long-Term Survival Outcomes of Metabolically Supported Chemotherapy with Gemcitabine-Based or FOLFIRINOX Regimen Combined with Ketogenic Diet, Hyperthermia, and Hyperbaric Oxygen Therapy in Metastatic Pancreatic Cancer

Abstract

Background: Despite introduction of new chemotherapeutic agents, outcomes of patients with metastatic pancreatic cancer are still poor. Metabolically supported chemotherapy (MSCT) is a novel approach targeting dysregulated energy mechanism of the tumor cell. Objectives: This study aimed to examine the efficacy of metabolically supported administration of chemotherapy combined with ketogenic diet, hyperthermia, and hyperbaric oxygen therapy (HBOT) in patients with metastatic pancreatic cancer. Method: This retrospective observational study included 25 patients with metastatic pancreatic ductal carcinoma (stage IV) who received MSCT (either gemcitabine-based or FOLFIRINOX regimen administered concomitantly with induced hypoglycemia) plus ketogenic diet, hyperthermia, and HBOT combination. Survival outcomes were evaluated. Results: During the mean follow-up duration of 25.4 ± 19.3 months, median overall survival and median progression-free survival were 15.8 months (95% CI, 10.5-21.1) and 12.9 months (95% CI, 11.2-14.6), respectively. Age and gender did not have any effect on overall survival (p > 0.05 for all). Conclusions: MSCT administered together with ketogenic diet, hyperthermia, and HBOT appears to be a viable option with the potential to improve survival outcomes in patients diagnosed with metastatic pancreatic cancer. Further research, particularly with larger comparative clinical trials, is warranted.
