Preventing Cancer Recurrence

1. METABOLIC THERAPIES

Targeting the altered metabolism of cancer cells can help prevent recurrence by modifying the tumor microenvironment and reducing metabolic fuel for residual cancer cells.

A. Ketogenic Diet

Mechanism: Reduces glycolysis-dependent energy production in cancer cells and lowers insulin/IGF-1 signaling.

B. Intermittent Fasting / Time-Restricted Feeding

Mechanism: Enhances autophagy, sensitizes cancer cells to chemotherapy, reduces insulin and inflammation.
Evidence:

C. Hyperbaric Oxygen Therapy (HBOT)

Mechanism: Enhances tissue oxygenation, which inhibits hypoxia-induced angiogenesis and supports immune function.
Evidence:
– D’Agostino, D. P., et al. “Hyperbaric oxygen therapy as an adjuvant for metabolic cancer therapy.” Cancer Lett. 2015;356(2 Pt A):233–239. DOI:10.1016/j.canlet.2014.10.031

D. Metformin

Mechanism: Activates AMPK, reduces circulating insulin, and inhibits mitochondrial complex I.
Evidence:
– Dowling, R. J. O. et al. “Metformin in cancer: Translational challenges.” J Mol Endocrinol. 2012;48(3):R31–R43. DOI:10.1530/JME-12-0007

2. PERSONALIZED PROTOCOLS

Precision oncology integrates genomic, metabolic, and immunologic profiling to tailor individualized prevention strategies.

A. Genomic Profiling

B. Liquid Biopsy (ctDNA, CTCs)

– Wan, J. C. M. et al. “Liquid biopsies come of age: towards implementation of circulating tumour DNA.” Nat Rev Cancer. 2017;17:223–238. DOI:10.1038/nrc.2017.7

C. Immune and Inflammatory Profiling

3. REPURPOSED PHARMACEUTICALS

Many non-cancer drugs demonstrate anticancer activity through metabolic, anti-inflammatory, and immune-modulatory mechanisms.

4. COMBINATION WITH CONVENTIONAL TREATMENTS

Combining metabolic and repurposed therapies with standard treatments provides synergistic benefits.

CONCLUSION

Cancer recurrence prevention demands a systems biology approach: one that incorporates metabolic rewiring, personalized diagnostics, repurposed drugs, and evidence-based conventional treatments. Survivors empowered with this integrated strategy can significantly reduce recurrence risk while enhancing quality of life.
