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.

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.
