Multiple dietary antioxidants enhance the efficacy of standard and experimental cancer therapies and decrease their...

Area of Science:

• Oncology
• Nutritional Science

Background:

• Cancer therapy faces challenges with plateauing efficacy for solid tumors and limited options for unresponsive patients.
• Survivors of cancer are at risk for recurrence or secondary malignancies, with no current strategies to mitigate this risk.

Purpose of the Study:

• To propose active and maintenance nutritional protocols using dietary antioxidants as adjuncts to conventional cancer therapies.
• To explore the potential of these protocols to improve treatment efficacy, reduce toxicity, enhance quality of life, and lower cancer recurrence risk.

Main Methods:

• Review of experimental data and limited human studies on the use of specific dietary antioxidants (vitamin C, alpha-tocopheryl succinate, natural beta-carotene).
• Proposal of distinct nutritional protocols for active treatment, for patients unresponsive to therapy, and for long-term maintenance.

Main Results:

• Adjunctive nutritional protocols may improve tumor response and decrease toxicity during radiation therapy, chemotherapy, or experimental therapies.
• Nutritional interventions could potentially improve quality of life and survival time for patients unresponsive to standard treatments.

Conclusions:

• Dietary antioxidant protocols show promise for improving oncologic outcomes and reducing treatment-related toxicity.
• Maintenance nutritional protocols, combined with lifestyle modifications, may reduce the risk of cancer recurrence and secondary cancers in survivors.
