From the Guidelines
High-dose Vitamin C (Ascorbic Acid) is not recommended for treating stage IV breast cancer due to lack of evidence showing its efficacy and potential for deleterious interactions with specific anticancer therapies. The most recent and highest quality study, published in 2018 in the Annals of Oncology 1, states that alternative therapies, including high-dose vitamins, are not recommended in any phase or stage of cancer treatment. This guideline is based on expert opinion and has a 100% consensus among panel members.
Key Points to Consider
- The use of high-dose vitamins, including Vitamin C, has been associated with no effect or even worse outcomes in patients with advanced breast cancer 1.
- Complementary therapies, such as physical exercise, mindfulness-based stress reduction, and acupuncture, may be beneficial in reducing disease symptom burden and improving quality of life, but should be used under the guidance of a healthcare professional 1.
- Patients considering alternative or complementary therapies should discuss them with their oncologist to ensure safe and effective care.
- The primary goals of systemic treatment of recurrent/stage IV breast cancer are palliating symptoms, prolonging survival, and maintaining or improving quality of life, and should be guided by evidence-based guidelines, such as those published by the National Comprehensive Cancer Network (NCCN) 1.
Clinical Implications
The lack of evidence supporting the use of high-dose Vitamin C in treating stage IV breast cancer, combined with the potential risks and interactions with other therapies, means that it should not be recommended as a treatment option. Instead, patients should focus on evidence-based treatments and complementary therapies that have been shown to improve quality of life and outcomes. Healthcare professionals should be aware of the potential use of alternative therapies by their patients and provide guidance on safe and effective care.
From the Research
Efficacy of High-Dose Vitamin C in Treating Stage IV Breast Cancer
- There are no research papers provided to directly answer the question about the efficacy of high-dose Vitamin C (Ascorbic Acid) in treating stage IV breast cancer 2, 3, 4, 5, 6.
- The provided studies discuss various treatment options for stage IV breast cancer, including systemic therapy, surgery, and targeted therapy, but do not mention the use of high-dose Vitamin C as a treatment method.
- Study 2 discusses the treatment of breast cancer based on the stage, but does not provide information on the use of Vitamin C in stage IV breast cancer treatment.
- Studies 3 and 5 examine the role of surgery in the treatment of stage IV breast cancer, while study 4 discusses advancements in targeted therapy and immunotherapy for breast cancer.
- Study 6 provides an overview of targeted therapy for breast cancer, but does not mention the use of high-dose Vitamin C as a treatment option.
