3 The Principles of Naturopathic Medicine:
Identify and Treat the Cause of Disease Do No Harm Doctor As Teacher Treat the Whole Person The Power of Prevention

4 Triple Negative Breast Cancer (TNBC)
Estrogen Receptor Negative Progesterone Receptor Negative Human Epidermal Growth Factor Receptor (HER2) Negative 15% of Breast Cancers Appear at an earlier age High Histologic Grade Define Cancer

5 Six TNBC Subtypes: 2 Basal Types Immunomodulatory Mesenchymal
Mesenchymal Stem-Like Luminal Androgen Receptor Each subtype has characteristics which may make it more or less susceptible to a particular type of therapy. Hopefully, as research progresses, it will become possible to use more patient-specific treatment strategies. PI3K- phosphatidylinositol-3-kinase, a signaling pathway, plays a role in growth and survival in many mammalian cancers P53- tumor suppressor gene, mutations occur in up to 82% of TNBC BRCA1 MIB-1 IGF-1R: Insulin like growth factor receptor, a tyrosine kinase, binds IGF. Ki67: a measure of cell proliferation, higher # ass. With axillary mets in TNBC mTOR:

6 Current TNBC Treatment Strategies
Cytotoxic Therapy (Adriamycin/Cytoxan/Taxol) Radiation Surgery Chemotherapy is considered a cytotoxic and systemic therapy aimed at destroying rapidly dividing cancer cells. Radiation: kills by ionizing DNA molecule within a cancer cells and the production of free radicals (hydroxyl radicals). At the present time these therapies have a low rate of success and new more efficacious treatments are needed. Adriamycin (docorubicin) Cytoxan (cyclophosphamide) Taxol (Paclitaxel)

7 Problems Associated with Current TNBC Treatment Strategy
Toxicity Immune Suppression Fatigue & Malaise Depression/Anxiety Drug Resistance Lack of Efficacy Ultimately a lack of efficacy. We need new therapies that provide better outcomes.

8 Naturopathic Treatment Strategies
As a way to support the patient: Promoting health of patient- both mind & body Minimizing treatment related side effects As integrative therapy: Anti-Cancer Therapy Improving clinical outcomes Preventing Re-occurrence Not anti-conventional treatments. Prefer integrative approach. Frequent Question: Can a person use CAM treatments with Conventional? Yes, as long as you use the right ones. How many people changed their diet when they were diagnosed? Yes = using CAM

9 Food As Medicine Dietary habits can play a role in both the development and progression of cancer. A healthy diet supports the body’s natural processes and functions. Inhibiting Unintended Weight Loss Promoting Healthy Elimination Reducing Treatment Related Side Effects Anti-inflammatory Action Energy Balance/Fatigue Reduction Improving Efficacy of Treatments Unintentional weight loss- either via LOA from treatment, or as a consequence of tumor Many tx’s are toxic- want them in and out, if elimination routes are inhibited (aka. Constipation) this can cause more toxicity issues, may also produce additional problems (impaction), additionally many drugs are nephrotoxic and maintaining good hydration keeps the kidneys safe. Tumor lysis syndrome and hydration In addition to bowel and urinary issues, healthy diets can also provide the body with what it needs to process chemicals and remove them from the body(cyp450 system). Some foods promote a decrease in the levels of inflammation present in the body: n-3: PGE2, fish oil: vitamin D3 Nutritionally deficient diets do not provide for sustained energy levels. Simple carbs = transient energy followed by a crash. If a patient does not maintain good health through their therapies then an extended chemo break, or dose-reduction is often needed. This can decrease efficacy.


Food As Medicine . INSULIN-LIKE GROWTH FACTOR-1 These results show that IGFs stimulate cell proliferation and promote cell survival in triple-negative breast cancer cell lines and warrant investigation of the IGF signal transduction pathway as a therapeutic target for the treatment of triple-negative breast cancer. Neoplasia Jun;13(6):504-15 Randomized controlled trials indicated that the circulating IGF-I level was significantly higher in the milk intervention group. Int J Food Sci Nutr. 2009;60 Suppl 7: Epub 2009 Sep 9. An unhealthy diet does not provide the same benefits, and instead can have significant negative impact Here is an example of a specific dietary manipulation aimed at inhibiting cancer growth: No dairy on TNBC diet? IGF-1 binds to IGF-1R , a hormone is one of the most potent natural activators of the AKT signaling pathway, a stimulator of cell growth and proliferation, and a potent inhibitor of programmed cell death (apoptosis). These data suggest that a plant-based diet is associated with lower circulating levels of total IGF-I. Cancer Epidemiol Biomarkers Prev Nov;11(11):

12 Food As Medicine “In vivo, the efficacy of blueberry to inhibit triple-negative breast tumor growth was evaluated. Tumor weight and proliferation (Ki-67 expression) were decreased in blueberry-treated mice, where apoptosis (caspase-3 expression) was increased compared with controls.” “In combination with standard treatments, supplementing the diet with (n-3) fatty acids may be a nontoxic means to improve cancer treatment outcomes and may slow or prevent recurrence of cancer.” Lung metastasis of TNBC was reduced (16-70%) by all treatments, significantly in the flax seed oil group. The distant lymph node metastasis was significantly decreased (52%) only in the flax seed oil group. The total metastasis incidence was lowered (42%). Mouse study. Ki67, a measure of proliferation, higher expressions of this associated with axillary mets.(PMID: ) PMID: PMID: ,

Food As Medicine SUGAR/CARBOHYDRATE/GLUCOSE = ENERGY Higher SUVmax and %Ki67 are associated with higher histologic grades. Histologic grade is a measure of proliferation, Scarff-Bloom-Richardson system most common rage from 3-9. Recall our definition of cancer. Cell reproduction (mitosis) takes energy. GLUT-1 receptors more expressed in TNBC (PMID: ) GLUT1 trasporters are upreg. When a cell is hungry. What are the effects of a high sugar/refined carbohydrate diet? PMID: Glucose receptors are upregulated in TNBC (PMID ) Higher sugar uptake by TNBC cells correlates with increased cancer cell proliferation (PMID: )

14 Exploiting Metabolism

15 Supplements for cancer?
Reasons for using supplements with conventional therapy: Minimize treatment-related side effects Promote a well functioning immune system Synergize with conventional treatments Are supplements safe with conventional care? Yes, if you take the right ones. Natural does not mean safe. How many capsules can a person eat in one day. Try to maximize effectiveness
