Probiotics

Oral Probiotics Reduce Complications of Surgery

 

Using probiotics before surgery prepares the patient for post operative stressors and complications. Using probiotics after surgery continues the support for the microbiome post operatively.

It is my practice to administer oral probiotics both before and after surgery with all of my patients.

Overall, using probiotics as part of pre-op and post-op care offers the following benefits

  • Reduction in Pro-Inflammatory Cytokines
  • Prevention of Surgical Infection and Sepsis 
  • Promotion of gastrointestinal microbial balance
  • Amelioration of adverse effects of oral antibiotics 
  • Decrease in adverse effects of opioids on gastrointestinal function
  • Promotion of Wound Healing at the surgical site

Use of oral probiotics is well tolerated and safe for use not only in cancer related surgeries but in a wide range of surgical procedures. 

Researchers conducting a randomized double blind placebo controlled study on the post operative effects of oral probiotics in patients undergoing resection for colorectal cancer concluded that probiotics not only decrease rates of infection at the incision site, respiratory and urinary systems but also inhibit proinflammatory factors such as TNFa, IL-17A , IL-17C, IL-22, IL-10 and IL-12.   Subjects in the treatment arm were given a 30 billion CFU mixture of six viable strains of Lactobacillus acidophilus, L. lactis, L. casei, Bifidobacterium longum, B. bifidum, and B. infantis twice daily for 6 months beginning 4 weeks postoperatively. [NB: I recommend starting pre-operatively].   Subjects in this arm did not experience infection, diarrhea or require antibiotics.

In another study of patients receiving abdominal surgeries  oral probiotics were administered for 8 weeks.  The strains included were  L. plantarum, L. lactis, and L. delbrueckii. The study found statistically significant postoperative treatment reductions in abdominal pain and bloating, and significant improvements in stool formation. No clinically relevant adverse events were reported, and the treatment was well-tolerated by all patients.

In a recent 2021 Review of 14 studies of patients receiving gastrointestinal surgeries, a disruption of intestinal microbiome is identified and the prevalence of specific bacteria had significantly changed after surgery.

Another Review of 10 studies also identified post operative changes in the composition of the intestinal microbiome in patients receiving gastrointestinal surgeries  and posits that complications after gastrointestinal surgeries are linked to changes in the composition of the gut flora.

A study on the use of specific probiotics in patients undergoing resection for  colorectal cancer concluded that inflammatory cytokines and serum zonulin levels significantly decreased with probiotics. Probiotic ingestion resulted in compositional changes in gut microbiota; greater increases and decreases in healthy vs pathogenic bacteria, respectively, occurred with probiotics. Compositional increase in healthy bacteria was associated with reduced white blood cells, neutrophils, neutrophil-lymphocyte ratio, and zonulin. Bifidobacterium composition was negatively correlated with zonulin levels in the probiotic group, indicating repair of intestinal epithelium as an effective barrier. Probiotics improved postoperative flatus control and modified postoperative changes in microbiota and inflammatory markers.   In this study oral probiotics were administered both pre-op and post-op.  Probiotic supplementation included a mixture of three probiotic strains (Bifidobacterium animalis subsp. lactis HY8002 (1 × 108 cfu), Lactobacillus casei HY2782 (5 × 107 cfu), and Lactobacillus plantarum HY7712 (5 × 107 cfu)

Preventing Abdominal Radiation Enteritis and Promoting Quality of Life in Gynecological Cancer Patients

 

Insulin and fructo-oligosaccharide prevent acute radiation enteritis in patients with gynecological cancer and improve quality-of-life

Insulin

Background/objectives: The pathogenesis of enteritis after abdominal radiotherapy (RT) is unknown, although changes in fecal microbiota may be involved. Prebiotics stimulate the proliferation of Lactobacillus spp and Bifidobacterium spp, and this may have positive effects on the intestinal mucosa during abdominal RT.

Subjects/methods: We performed a randomized, double-blind, placebo-controlled trial involving patients with gynecological cancer who received abdominal RT after surgery. Patients were randomized to receive prebiotics or placebo. The prebiotic group received a mixture of fiber (50 inulin and 50% fructo-oligosaccharide), and the placebo group received 6 g of maltodextrin twice daily from 1 week before to 3 weeks after RT. The number of bowel movements and stool consistency was recorded daily. Diarrhea was evaluated according to the Common Toxicity Criteria of the National Cancer Institute. Stool consistency was assessed using the 7-point Bristol scale. Patients' quality-of-life was evaluated at baseline and at completion of RT using the EORTC-QLQ-C30 (European Organization for Research and Treatment of Cancer quality-of-life Questionnaire C30) test.

Results: Thirty-eight women with a mean age of 60.3±11.8 years participated in the study. Both groups (prebiotic (n=20) and placebo (n=18)) were comparable in their baseline characteristics. The number of bowel movements per month increased in both groups during RT. The number of bowel movements per day increased in both groups. The number of days with watery stool (Bristol score 7) was lower in the prebiotic group (3.3±4.4 to 2.2±1.6) than in the placebo group (P=0.08). With respect to quality-of-life, the symptoms with the highest score in the placebo group were insomnia at baseline and diarrhea toward the end of the treatment.

bowel movements

In the prebiotic group, insomnia was the symptom with the highest score at both assessments, although the differences were not statistically significant.

Conclusions: Prebiotics can improve the consistency of stools in gynecologic cancer patients on RT. This finding could have important implications in the quality-of-life of these patients during treatment.

How Evolution Helps Us Understand and Treat Cancer

The Cheating CellThe Cheating Cell: How Evolution Helps Us Understand and Treat Cancer - by Athena Aktipis

A fundamental and groundbreaking reassessment of how we view and manage cancer

When we think of the forces driving cancer, we don’t necessarily think of evolution. But evolution and cancer are closely linked, for the historical processes that created life also created cancer. The Cheating Cell delves into this extraordinary relationship, and shows that by understanding cancer’s evolutionary origins, researchers can come up with more effective, revolutionary treatments.

 

 

Athena Aktipis goes back billions of years to explore when unicellular forms became multicellular organisms. Within these bodies of cooperating cells, cheating ones arose, overusing resources and replicating out of control, giving rise to cancer.

Aktipis illustrates how evolution has paved the way for cancer’s ubiquity, and why it will exist as long as multicellular life does.

Even so, she argues, this doesn’t mean we should give up on treating cancer—in fact, evolutionary approaches offer new and promising options for the disease’s prevention and treatments that aim at long-term management rather than simple eradication.

Looking across species—from sponges and cacti to dogs and elephants—we are discovering new mechanisms of tumor suppression and the many ways that multicellular life-forms have evolved to keep cancer under control.

By accepting that cancer is a part of our biological past, present, and future—and that we cannot win a war against evolution—treatments can become smarter, more strategic, and more humane.

Unifying the latest research from biology, ecology, medicine, and social science, The Cheating Cell challenges us to rethink cancer’s fundamental nature and our relationship to it.

Selected Prognostic Cancer Biomarkers from Common Blood Tests

What Can You Learn About Cancer Survival from a CBC?

Common Biomarkers, Cancer Progression and Survival

tumor microenvironment

An excellent paper "Inflammatory markers in cancer: Potential resources * is a thorough and detailed discussion of routinely measured Cancer Biomarkers found in the inflamed tumor microenvironment that are indicative of immune capacity and prognosis. Clinicians will typically have access to a current CBC (Complete Blood Count) with differential and can readily calculate the lymphocyte ratios below

The presence of inflammatory markers is linked to both risks of cancer development and cancer survival.  Cancer-related inflammation is associated with tumorigenesis and tumor progression. Increased levels of multiple biomarkers are present in the tumor microenvironment.

A thorough evaluation will include Cytokines, Leukocytes, Acute-phase proteins (ferritin, ceruloplasmin, CRP).     

Although not routinely measured, prostaglandins, cyclooxygenases, lipoxygenases, transcription factors, and LDH may be elevated. 

Cancer Related Inflammation Promotes

  • Tumor Growth
  • Proliferation
  • Progression
  • Angiogenesis  
  • Metastasis
  • Thrombus Formation
  • Immune Suppression
  • Cancer Related Fatigue  
  • Depression
  • Pain

Selected Prognostic Cancer Biomarkers from the CBC and CMP

  • Neutrophil: Lymphocyte Ratio
  • Lymphocyte: Monocyte Ratio
  • Platelet: Lymphocyte Ratio
  • CRP: Albumin Ratio
  • Hypoalbuminemia

Neutrophil / Lymphocyte Ratio (NLR)

  • Neutrophyl LymphocytesThe neutrophils act as tumor-promoting leukocytes, capable of suppressing anti-tumor immune response; are effectors of angiogenesis; promote leakage of tumor cells and endothelial cells into the circulation, therefore contributing to participate in the metastatic cascade. Therefore, an elevated neutrophil count can stimulate tumor angiogenesis and contribute to disease progression, thus leading to a negative correlation between neutrophil density and patient survival. 
  • On the other hand, lymphocytes are a part of the host’s antitumor response the presence of lymphocytes in the tumor is associated with better responses to chemotherapy and better prognosis. 
  • Thus, the NLR can reflect the balance between the activation of the inflammatory pathway and the antitumor immune function. 
  • The division of neutrophil count by lymphocyte count is defined as NLR. 
  • An increase in NLR has been reported to correlate with poor prognosis in cancer patients.
  • A cut-off value between 2-4 has been reported in cancer patients.

Lymphocyte/Monocyte Ratio (LMR) 

  • Lymphocytopenia has been associated with increased tumor burden and poor prognosis. The probable cause could be the destruction of lymphocytes by tumor cells which decreases the body’s anti-tumor response.
  • Monocytosis has also been found to be associated with poor prognosis as they Tumor-associated macrophages, which are an important mediator of cancer progression and metastases. 
  • The division of lymphocyte count by monocyte count is defined as LMR. 
  • A low LMR as a simple biomarker of the host immune system has been suggested to be related to poor prognosis in various cancers. 
  • The median cut-off value for LMR has been reported to be 3.0.

Platelet/Lymphocyte Ratio (PLR)

  • Platelet/ LymphocytePlatelets are another important tumor-promoting leukocyte. They secrete vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), platelet-derived growth factor (PDGF), hepatocyte growth factor (HGF), insulin-like growth factor (IGF), transforming growth factor β (TGFβ), and many cytokines which promote epithelial to mesenchymal transition (EMT) and promote metastasis.
  • Lymphocytes, as we know, are part of the host's defense against tumors. 
  • The division of platelet count by lymphocyte count is defined as PLR. 
  • The cutoff value estimated for PLR is 160. 
  • A high PLR value correlates with a poor response to therapy and a bad prognosis.

Prostate Cancer Chemoprevention: I3C and DIM

Increasing serum levels of phytochemical DIM may be chemopreventive and chemoprotective for prostate cancer.

Cruciferous Cabbage Family vegetables such as (including cabbage, cauliflower, Brussels sprouts, broccoli, kale, arugula, bok choy and more ) are rich in dietary phytochemicals including Sulforaphane-Glucosinolate family molecules 13C (Indole-3-Carbinol) and it’s major bioactive therapeutic metabolite DIM  (3 3’di-indole methane).

Chopping, chewing, massaging and lightly steaming cruciferous vegetables activates the plants own catalyzing myrosinase enzyme and exposing the plant to the acid environment in the stomach leading to further metabolism resulting in bio available and bio active DIM.  DIM levels can be measured in the serum.

There are numerous studies on the benefits of dietary consumption of cruciferous vegetables.. A high intake of cruciferous vegetables is associated with reduced risk of several human cancers.  There are strong associations between high intake of broccoli and breast cancer and prostate cancer in humans.  Human cell studies show inhibition of  cell growth of several cancers including breast, prostate, pancreatic, colorectal, lung and head and neck cancers.

DIM and Prostate Cancer

DIM

DIM appears to be a potent inhibitor of human androgen hormones which may promote expression of androgen receptors on prostate cancer cells which may lead to carcinogenesis. Increasing serum levels of DIM through diet and supplementation may therefore be chemopreventive for prostate cancer.

Human and Cell Studies have shown that increased serum levels of DIM 

  • Reduces Serum Prostate Specific Antigen
  • Reduces Serum Androgen Hormones
  • Down Regulates Prostate Stem Cell Activity
  • Decreases  Nuclear Androgen Receptors
  • Induces p450 metabolic detoxification enzymes CYP1A1, CYP1A2 and CYP1B
  • Decreases oxidative stress via nrf2-KEAP pathway

The OutSmart Cancer® System is focused upon transforming the tumor microenvironment  which is a signaling environment, so that there is less physiologic support for the development and spread of cancer.   In a health model (rather than a disease model) we endeavor to transform the biosystem and  reduce pro-carcinogenic and proliferative signaling and prevent cellular, nuclear and mitochondrial damage.

brocolli

Therefore we use phytochemicals such as I3C and DIM and dietary interventions to influence carcinogenic and proliferative signaling in the tumor microenvironment.

omega 3 fatty acids

Omega 3 Fatty Acids: Enhanced Control of Cancer Risk and Progression

A diet high in polyunsaturated fatty acids, especially omega 3s, have been shown to be negatively associated with cancer development

 Dietary fatty acids have been recognized as influential factors in the activation of carcinogenic events or disease progression and have been associated with a direct connection to breast cancer prevention.

PUFAs differentially inhibit mammary tumor development by inflicting modifications to the morphology of cell membranes, and influencing signaling pathways, gene expression and apoptosis.

The human body is unable to synthesize long-chain polyunsaturated fatty acids (PUFAs) Omega 3 DHA, docosahexaenoic, and EPA, Eicosapentaenoic acid and Omega 6 Arachidonic Acid at a reasonable rate and therefore, supplementation is required through dietary sources or nutritional supplements. The recommended daily nutritional dose is 2,000 mg EPA+DHA, while therapeutic dosing is 4,000-6,000 milligrams of EPA+DHA per day.

omega-3-natural

 Omega Three Fatty Acids and the Tumor Microenvironment

  1. Supports Normal Inflammation Control by lowering COX 2, LOX5, PGE2, IL1, IL6,TNFa, CRP.
    • Increased inflammation contributes to cancer development, progression and metastasis.
    • Increased inflammation is linked to cancer related pain, fatigue, depression and cognitive impairment.
    • Increased inflammation is linked to cancer related hypercoagulation and risk of thromboembolism
    • Supporting Normal Inflammation control has a wide impact on the behavior of tumor cells and on safety and quality of life for cancer patients and survivors.
  2. Promotes Expression of M1 Type Tumor Associated Macrophages (TAMs).
    • Type M1 TAMs promote tumor regression, inflammation control and immune activation by promoting tumor infiltration by antigen presenting dendritic cells and cytotoxic T cells.
  3. Inhibits VEGF (Vascular Endothelial Growth Factor) and Promotes Normal Control of Angiogenesis .
    • VEGF promotes the development of new blood vessels to the tumor cells. Inhibition of VEGF and the development of capillaries inhibits tumor growth and profession as well as metastasis.
       
  4. Down regulates tumor promoter Protein Kinase C isoenzymes,
    • A group of enzymes that link multiple cellular processes responsible for regulation of tumorigenesis, cell cycle progression and metastasis.
  5. Inhibits Collagenase,
    • A proteolytic enzyme that breaks down the ECM (Extracellular Matrix) and allows invasion of tumor cells into tissues and blood vessels, leading to progression, invasion and metastasis.
  6. Promotes Normal Apoptosis signaling.
    • Cancer cells lose the ability to initiate apoptosis, the normal process in which a cell recognizes itself as aberrant and self destructs. The inhibition of normal apoptotic signaling in malignant cells is a hallmark  of the tumor microenvironment permissive of uncontrolled growth, persistence and immortality due to loss of normal regulation.
  7. Lowers Bcl2 and Ras oncogenes.
    • These genes inhibit normal apoptosis and promote tumor growth and progression.
  8. Acts as a Chemo-sensitizer
    • Working synergistically to enhance therapeutic effect of chemotherapy drugs. DHA has a potential to specifically chemo-sensitize tumors.
    • Tumour cells can be made more sensitive to chemotherapy than non-tumor cell when membrane lipids are enriched with DHA
    • Incorporating DHA during treatment reduces adverse effects of chemotherapy.
    • DHA can improve the outcome of chemotherapy when highly incorporated into cell membranes.
  9. Acts as a Radio-sensitizer.
    • By promoting normal membrane structure and function and by influencing the tumor microenvironment DHA acts synergistically to potentiate therapeutic effects of radiotherapy on tumor cells.
  10. Promotes Healthy 16-OH Estrogen metabolism.
    • Estrogen can be metabolized through multiple pathways. The promotion of 16-Hydroxylation of estrogen produces estrogen metabolites that are not pro-carcinogenic. Omega 3 Fatty Acids promote healthy estrogen metabolism.
  11. Inhibits Platelet Aggregation and Thrombin Formation.
    • Abnormal hyper-coagulation, increased platelet aggregation and thrombus formation are hallmarks of the tumor microenvironment. Control of platelet aggregation and thrombus formation reduces the risk of life threatening and adverse  thrombotic events.  40% of all cancer patients are at risk for the formation of thromboembolisms.  Omega 3 Fatty Acids reduce this risk.
  12. Promotes Normal Cell Membrane Functions and Receptor Binding
    • A healthy flexible cell membrane built of omega 3 fatty acids promotes an enhancement of all membrane functions, normalizing and optimizing normal and therapeutic physiology.
  13. Increases expression of Tumor Suppressor Gene PTEN.
    • Increased expression of tumor suppressor genes leads to enhanced control over carcinogenesis,  tumorigenesis and metastatic progression.
  14. Inhibits Multi Drug Resistance.
    • Tumor cells can quickly become resistant to therapeutic anti-neoplastic agents thus decreasing and shortening the efficacy of treatments.
  15. Inhibits cachexia preserves muscle mass and bone mass (inhibits proteolysis inducing factor)
    • Loss of bone mass (osteopenia) and loss of muscle mass (sarcopenia) are risk factors of aging and of the cancer physiology.  Maintaining bone mass and muscle mass are crucial to robust healthy function and quality of life.
  16. Supports normal mood regulation.
    • Depression and anxiety are common in cancer patients. Support of balanced mood allows cancer patients deep and restful sleep, improved quality of life and increased coping capacity and resilience in the face of stress.

Cautions and Contraindications

MRI

Innovative MRI without Toxic Gadolinium Contrast Media

PreNuvo: Innovative MRI Technology

High-resolution radiology is used in oncology for both diagnoses as well as screening and monitoring. Because cancer cell physiology is metabolically different from healthy cells, contrast media are preferentially taken up by cancer cells allowing for more precise imaging.

Magnetic Resonance Imaging (MRI)  was invented in the 1980s.  It is a magnetic technology and does not expose patients to ionizing radiation, but to magnetic fields.  Hence it is considered safer than exposure to the damaging, oncogenic ionizing radiation found in X-Rays and PET and CT scans

Say No to Gadolinium
The most commonly used contrast medium used with MRI imaging to enhance resolution is Gadolinium. Gadolinium is a  magnetic metal that is engineered into a nanoparticle solution and injected into the vein.

Gadolinium can damage both nephrons and neurons and is not completely excreted leading to toxic load over time.  Because cancer patients may have multiple scans per year over many years, exposure to Gadolinium can become damaging and increasingly toxic. Gadolinium also acts as a calcium channel blocker and even at low concentrations can interfere with the contraction of smooth, skeletal, and cardiac muscle, nerve impulses, and blood coagulation.

Furthermore, there is a syndrome called Gadolinium deposition disease that is a gadolinium storage condition for which the long-term effects are not well understood.  A common adverse effect of Gadolinium exposure and retention is renal fibrosis.

Patients should discuss the risks of ALL contrast media with the radiology team to evaluate risks and benefits and be fully informed before proceeding with any scan.  Because all contrast media has toxicity, the opportunity to have a high-resolution scan without the use of Gadolinium contrast media is a very important innovation.

Patients with compromised cardiovascular, renal and neurologic function should use cautions before authorizing the performance of any scan without a full understanding of toxicity, risks, and benefits of contrast media

What if A High-Resolution MRI was possible without toxic contrast media?

PreNuvo has developed a High-Resolution MRI Scan that does not require the use of Gadolinium contrast media.

As with all technologies, MRI technology is advancing. Prenuvo is a company on the forefront of MRI Innovation bringing new safe and effective techniques not requiring contrast medium for high-resolution whole-body imaging, making accurate diagnosis possible.

Prenuvo uses innovative new hardware, software, and sequencing to create more detailed comprehensive images along with the use of Artificial Intelligence to enhance accurate analysis in less time.  Prenuvo claims a 0.7% false-positive rate due to the higher resolution, often decreasing the need for additional follow-up imaging, biopsies, or surgeries.  All without the use of Gadolinium or any other contrast media.

A more comfortable patient-centric experience:
A whole-body scan at Prenuvo typically takes 60 minutes compared to 5 hours for a conventional MRI.  The scanner itself is wider and more open and less claustrophobic with fresh air vents.  The machine is much quieter as opposed to the loud clanking of the conventional MRI.  The design also allows the patient’s head to remain outside of the scanner for most of the scan.  Innovative design and technology also solve many of the issues that lead to stress and anxiety for the patient that is common with MRI scans.  Additionally, a headset and a music menu are provided to support relaxation.

For a faster, safer, less toxic, and highly accurate MRI without contrast, I recommend that you explore the use of prenuvo.com for your patients.

How does Copper Drive Cancer Progression?

Key Takeaways:

This initiation of Angiogenesis is one of the steps of disease progression and acceleration, Creating an environment where this is contained is very powerful.

  • Controlling Copper and Angiogenesis is a mechanism
  • No one ever dies of a primary tumor for the most part, it is metastatic disease that kills the cancer patients
  • The more we can contain tumor progression, travel and desize, patients can live with metastatic disease for quite a long time, if we can control it
  • There's no kill rate to the tumor cell when you inhibit Angiogenesis, by any means whether it's a drug or copper culation
  • If we lower copper in a patient whose had a good reduction of their tumor burden, by any means, surgery, chemotherapy and immunotherapy... And then we track their copper, keeping copper in the lowest quartile of normal, usually their disease does not progress.
  • You reduce Inflammation when you reduce copper

The Link between Bone Density and Breast Cancer Risk

Understanding and Monitoring Risk Factors

Bone density, or bone mineral density ( BMD ), is the amount of bone mineral in bone tissue.  Bone mineral density (BMD) is a lifetime marker of estrogen exposure in a woman's body and has been associated with increased breast cancer risk. Estrogen is a crucial factor in maintaining bone density and gradually decreases over age. While there are many factors that influence bone density and bone health, the presence of estrogen contributes to the capacity of bone to continuously remodel and maintain the dynamic balance between bone resorption and bone formation.  A woman’s exposure to estrogen over the life cycle may contribute to her risk of breast cancer.

breast-cancer

Bone density measurement is used in clinical medicine as an indirect indicator of osteoporosis and fracture risk.  There is a clear association between poor bone density and a higher probability of fracture.  There is a clear association between poor bone density and low estrogen levels.  Conversely, there is a clear association between increased and healthy bone density and higher estrogen levels.

pink-ribbonScreening for risk of breast cancer should ALSO include assessment of estrogen levels and bone density along with well-recognized risk factors which include first degree relatives, obesity, increased visceral fat, smoking, alcoholism, early menarche, late menopause, sedentary lifestyle, hormone replacement therapy, and prolonged estrogen exposure, increased density of breast tissue. 

I would also add exposure to environmental endocrine disruptors and imbalances in the intestinal microbiome influencing estrogen metabolism.  

Breast density and bone density are related to endogenous and exogenous estrogen exposure in a woman’s body.  There is a correlation between estrogen exposure, high breast density, high bone density, and increased risk of breast cancer.

Bone is living metabolically active tissue. “Bone remodeling is the process by which bone is renewed to maintain bone strength and mineral homeostasis. Remodeling involves continuous removal of discrete packets of old bone, replacement of these packets with newly synthesized proteinaceous matrix, and subsequent mineralization of the matrix to form new bone begins before birth and continues until death.  Bone remodeling increases in perimenopausal and early postmenopausal women and then slows with further aging, but continues at a faster rate than in premenopausal women. Bone remodeling is thought to increase mildly in aging men.”  Normal Bone Anatomy and Physiology 10.2215/CJN.04151206

Engaging in a health model for all patients includes assessing and managing bone health to promote healthy bone over the life cycle. A health model for cancer patients, due to the typically older age demographics will inherently include a large population of patients already at risk for loss of bone mass, osteopenia and osteoporosis. Screening for bone mineral density and managing bone health should be part of whole-person, whole health care. Taking a thorough history that includes family history, bone health and bone mineral density can bring attention to patients at higher risk for low bone density and fracture as well as patients with a higher risk of estrogen driven breast cancers.

Bone density measurement is used in clinical medicine as an indirect indicator of osteoporosis and fracture risk.  There is a clear association between poor bone density and higher probability of fracture.  There is a clear association between poor bone density and low estrogen levels.  Conversely there is a clear association between increased and healthy bone density and higher estrogen levels.

The Most Common Risk Factors for Low Bone Density and Primary Considerations for a Bone Density Test include:

bone-density 

  • Females age 65 or older
  • Males aged 70 or older
  • People over age 50 with
    • previous bone fracture from minor trauma
    • rheumatoid arthritis
    • low body weight
    • a parent with a hip fracture
  • Individuals with vertebral abnormalities
  • Individuals receiving, or planning to receive, long-term glucocorticoid therapy
  • Individuals with primary hyperparathyroidism
  • Individuals being monitored to assess the response or efficacy of an approved osteoporosis drug therapy
  • Individuals receiving androgen deprivation therapy 
  • Individuals with a history of eating disorders

Additional factors that are related to the risk of low bone density and the need for assessment include smoking, alcohol intake, long-term use of corticosteroid drugs, sedentary or convalescent lifestyle, protein status, mineral status, digestion, and absorption function, chronic inflammation and vitamin D status.  

For cancer patients and survivors also consider periods of poor nutrition, calorie, protein status, convalescence, lack of exercise, effect of hormonal therapies, oophorectomy, orchiectomy, chemotherapy, immunotherapy, treatment induced thyroiditis, gastritis, enteritis and colitis,  chronic pain impacting appetite, digestive and absorptive dysfunction, surgical loss of gastrointestinal organs and function as contributors to risk of loss of bone density and as well as multiple and varied adverse effects of cancer physiology and cancer treatments upon nutritional status and active lifestyle.

Should PreMenopausal Breast Cancer Patients Receive Endocrine Therapy?

 

Endocrine Therapy Provides TwentyYear Benefit in ER+ Breast Cancer

Integrative and Individualized cancer care is the best cancer care and yields the best long term outcomes. Making individualized care decisions and including a health model, not just a disease model and following the OutSmart Cancer® Diet Guidelines are core principles of the OutSmart Cancer® System.

Two years of adjuvant endocrine therapy in premenopausal patients with estrogen receptor-positive (ER+) breast cancer can reduce the risk of recurrence at 20 years, according to a study published in the Journal of Clinical Oncology. (2)  This study is meaningful because many oncologists recommend five to ten years of endocrine therapy.  This study clearly demonstrates that only two years is sufficient to significantly reduce risk of breast cancer recurrence 20 years after completion of conventional oncology treatment.  This study also demonstrates that women who are candidates for and who do not receive endocrine therapy have worse outcomes. 

Furthermore this study demonstrates that women with low genomic risk should receive tamoxifen and women with high genomic risk should receive goserilin for best long term outcomes.

By including an integrative approach utilizing the health principles of the OutSmart Cancer® System, we can further manage the side effects of these treatments and support healthy function and quality of life for these women.

OUTSMART CANCER SYSTEM® Integrative Approach and Health Focussed Model

chinese-characterEspecially supportive to management of adverse menopausal effects of endocrine therapy include acupuncture therapy(3), copper free bone mineral formula and optimized Vitamin D as well as traditional Chinese Herbal Tonics

 that nourish yin and blood and support kidney qi to modulate menopausal symptoms without estrogenic effects such as Er Xian Tang (Two Immortals Formula)  and also formulas to address hormone depletion related mood dysregulation, depression and irritability such as Shu Gan Tang (Buplerum and Evodia Combination) to harmonize the liver qi and relieve stagnation of blood and emotions.  Furthermore, patients with estrogenic cancers should be given guidance on restricting estrogenic foods from their diets as part of a lifelong plan to prevent recurrence. For example,  both red meat (7) and alcohol (6) are known carcinogens linked to promotion of breast cancer and should be restricted.  Following the OutSmart Cancer® Diet Guidelines is recommended 

Monitoring for complications of endocrine therapies

Patients receiving Tamoxifen therapy  (an oral selective estrogen receptor modifier) should have semi-annual uterine ultrasound to measure endometrial thickness to assess risk of uterine hyperplasia and neoplasm as a risk of tamoxifen therapy.

Patient receiving goserilin  (an injectabl luteinizing hormone releasing hormone antagonist administered subcutaneously either every month or every 3 months) should monitor bone density by having a baseline DEXA bone density scan at inception and at 2 years and also Urine N-Telopeptide assay to monitor rate of loss of bone minerals due to medical menopause and estrogen blockade.

Results of Study

Researchers observed significant improvements in long-term distant recurrence-free interval (DRFI) for patients who received goserelin alone, tamoxifen alone, or the combination of goserelin and tamoxifen, when compared with patients who did not receive endocrine therapy. 

However, combination goserelin and tamoxifen did not improve DRFI when compared with either agent alone.

Researchers assessed the 20-year benefit of endocrine therapy by analyzing data from the Stockholm trial (1990-1997). The analysis included 584 patients with ER+ breast cancer. The median age at baseline was 47 (range, 26-55) years, 91% of patients had progesterone receptor-positive tumors, and 88% had HER2-negative tumors.

Patients were randomly assigned to 2 years of goserelin (n=155), tamoxifen (n=135), combined goserelin and tamoxifen (n=149), or no adjuvant endocrine therapy (n=145).

In a multivariable analysis, any endocrine therapy was associated with a significant improvement in long-term DRFI, when compared with no endocrine therapy. 

There was a significant improvement in DRFI with goserelin alone (hazard ratio [HR], 0.49; 95% CI, 0.32-0.75), tamoxifen alone (HR, 0.57; 95% CI, 0.38-0.87), and goserelin plus tamoxifen (HR, 0.63; 95% CI, 0.42-0.94). 

However, there was no significant long-term benefit from the combination of goserelin plus tamoxifen, when compared with either agent alone. There was a significant interaction between goserelin and tamoxifen (P =.016). 

The researchers also assessed the long-term benefit of endocrine therapy in patients with low genomic risk (n=305) and those with high genomic risk (n=158). 

Patients with low-risk genomics had a significant improvement in DRFI with tamoxifen (HR, 0.24; 95% CI, 0.10-0.60), and patients with high-risk genomics had a significant improvement in DRFI with goserelin (HR, 0.24; 95% CI, 0.10-0.54).

Patients with high-risk genomics had significantly worse DRFI when tamoxifen was added to goserelin (HR, 3.36; 95% CI, 1.39-8.07). The interaction between goserelin and tamoxifen was significant in high-risk patients (P =.006) but not in low-risk patients (P =.080). 

“This study demonstrates long-term benefit from 2 years of adjuvant endocrine therapy in ER-positive premenopausal patients,” the researchers concluded. “Furthermore, it suggests long-lasting benefit from tamoxifen in genomic low-risk patients with long-term risk of distant recurrence, whereas genomic high-risk patients have early risk and benefit from goserelin.”

Isoflavones genistein and daidizen are phytochemicals derived from soy act  that act as MILD selective estrogen receptor modulators. These isoflavones need to be taken in very high doses on a long term basis to achieve a clinical impact and are mild in comparison to pharmaceuticals.  A recommended daily dose of genistein is 1000mg 3x/day

This study will help us support patients in making educated and informed choices and in making sure that their oncologists are practicing in accordance with the most current research and guidelines and that patients
