What was done

A retrospective observational study evaluated 25 patients with stage IV metastatic pancreatic ductal carcinoma treated with metabolically supported chemotherapy (MSCT; either gemcitabine-based or FOLFIRINOX regimens administered alongside induced hypoglycemia) in combination with a ketogenic diet, hyperthermia, and hyperbaric oxygen therapy (HBOT). Survival outcomes were assessed over a mean follow-up period of 25.4 ± 19.3 months.

What was found

Median overall survival was 15.8 months (95% CI, 10.5–21.1) and median progression-free survival was 12.9 months (95% CI, 11.2–14.6). Neither age nor gender significantly influenced overall survival (p > 0.05 for all comparisons).

Why it matters

This study reports survival parameters for a multimodal metabolic protocol combined with standard chemotherapy in stage IV pancreatic cancer. It provides preliminary descriptive data for a complementary oncology regimen.

Limits

The study is limited by a very small sample size (n = 25), a retrospective single-arm design, and lack of a control or randomized comparator group. The multiple simultaneous interventions (induced hypoglycemia, dietary changes, hyperthermia, and HBOT) make it impossible to determine the relative contribution or efficacy of any single component.
