Book Review: You Finished Treatment-Now What?

 

A Field Guide for Cancer Survivors.
By Dr. Amy Rothenberg

You-Finished-Treatment-Now What

You Finished Treatment, Now What? A Field Guide for Cancer Survivors by Dr. Amy Rothberg is a roadmap for lifestyle and natural medicine approaches to address health challenges that persist after cancer care, and to reduce the risk of recurrence.

Dr Rothenberg wrote this guide for cancer survivors and those on their support and care team.

You Finished Treatment, highlights the evidence for an integrative approach to healing that Dr. Rothenberg has used for over 37 years practicing as a licensed naturopathic doctor.

She is also a breast and ovarian cancer survivor/thriver herself. She wrote this book to make sense of an overwhelming topic, in a user-friendly, accessible way, providing both actionable information and inspiration.

As a survivor/thriver of both ovarian cancer and breast cancer she speaks both from the physician’s and the patient’s point of view with heart, levity and solid, practical advice.

When diagnosed with cancer in 2014, Dr. Rothenberg sought and received state-of-the-art care at a renowned teaching hospital and had her own naturopathic medical team to help her best handle treatment, and rebound afterward.

Her writing is evidence-informed, while also bringing her personal experience as a doctor, patient, wife, mother, sister, and friend. Offering a natural, integrative medicine perspective on items in the news, find Dr.

This is an example of the principles employed in Dr. Chilkov’s OutSmart Cancer® System which is an integrative approach to combining the best of modern oncology with the best of research informed modern and traditional naturopathic systems of medicine for the very best outcomes.

This approach allows patients to have not only a plan for their disease, but also a plan to support their health during and after treatment and to support recovery, restoration and rejuvenation in support of both healthspan and lifespan.

Dr. Rothenberg’s both personal experiences and medical expertise combine to form a heartful and pragmatic approach with clear guidelines and recommendations. This book is a wonderful resource for both patients and families as well as care providers.

Changing the Management of Cancer with Personalized Testing

 

Personalized cDNA surveillance for patients with high-risk breast cancer

Is there a more sensitive technology that can detect preclinical breast cancer progression?

It is now possible to monitor fragments of cell free tumor DNA (ctDNA) circulating in the blood. This falls under the umbrella of “liquid biopsies” which monitor tumor burden, tumor response to treatment and early signs of recurrence or progression without a scan or need for a new surgical or biopsy tissue sample.

  • “Up to 30% of patients with breast cancer relapse after primary treatment.
  • There are no sensitive and reliable tests to monitor these patients and detect distant metastases before overt recurrence.
  • Breast cancer cell free tumor DNA blood test (liquid biopsy) can detect recurrence up to 2 years earlier than currently available conventional serum tumor markers and radiologic studies.
  • Cell free tumor DNA assays predict breast cancer recurrence earlier and with greater accuracy than traditional tools by using a highly-personalized molecular residual disease assay.

A cell free tumor DNA (ctDNA) assay is a personalized, tumor-informed assay with the power to give you earlier, clearer insight into your patient's disease. By detecting and quantifying ctDNA, you can optimize your ability to assess risk, predict recurrence, and monitor treatment response in those most at risk for progression.

This technology can be used to monitor a wide range of cancers. While this type of monitoring has not yet been widely adopted as “standard of care” I encourage you to educate all of your patients and their care providers to adopt the use of this highly reliable screening tool now.

Here, we demonstrate the use of personalized circulating tumor DNA (ctDNA) profiling for detection of recurrence in breast cancer.”

Cell free tumor DNA assays use a sample of the patient’s tumor tissue to develop a unique DNA fingerprint. After that, follow-up blood draws capture changes in the level of ctDNA, giving clinicians a better picture of a patient’s risk of recurrence without the need for another tissue sample and may decrease the need for frequent scans and repeated frequency of exposure to radiation and contrast material.

neodjuvant

A recent study “demonstrates that patient specific ctDNA analysis can be a sensitive and specific approach for disease surveillance for patients with breast cancer. More importantly, earlier detection of up to 2 years provides a possible window for therapeutic intervention. “(1)

Currently, there are no sensitive and specific clinical tests available to follow patients with breast cancer after primary treatment. Signatera developed a patient-specific method to analyze circulating tumor DNA (ctDNA) that allows for monitoring of these patients regardless of molecular genotype. In this study, we analyzed 208 blood samples from 49 patients monitored longitudinally for up to 4 years after completion of adjuvant chemotherapy to determine whether personalized ctDNA assays can allow for more effective monitoring than current clinical tests such as CA 15-3. Remarkably, for the patients that recurred, our test detected molecular relapse up to 2 years ahead of clinical relapse (median, 8.9 months) with 89% sensitivity and 100% specificity. This may provide a critical window of opportunity for additional therapeutic intervention.” (1)

hope

Data from a retrospective cohort analysis of EBLIS, a study designed to determine the lead interval between ctDNA detection and clinical metastatic disease, and to determine whether ctDNA in plasma can detect recurrent disease earlier than traditional methods, demonstrated that Signatera can accurately predicts metastatic relapse with a significant lead time over imaging and CA 15-3 (200 days on average)

Neoadjuvant

“…our study shows promise that early response prediction by highly sensitive ctDNA analysis in high-risk early breast cancer patients may facilitate a timely and judicious change in treatment to improve patients’ chances of achieving favorable long-term outcomes.(2)

Surveillance

Patients undergoing treatment as well as those who have completed their course of treatment can be assessed both for response to treatment during a course of therapy as well as for early signs of reurrence after treatment has been completed. In a study of patients undergoing treatment with Pembrolizumab, a checkpoint inhibitor.

“Baseline ctDNA concentration correlated with progression-free survival, overall survival, clinical response and clinical benefit. This association became stronger when considering ctDNA kinetics during treatment. All 12 patients with ctDNA clearance during treatment were alive with median 25 months follow up. This study demonstrates the potential for broad clinical utility of ctDNA-based surveillance in patients treated with ICB.” (3)

Recommended labs offering this technology include Natera, INVITAE, Foundation One, Caris Life Sciences. All of these labs are highly regarded in the oncology community. (Disclosure: I have no financial relationships with any of the labs recommended in this article.)

How often should these assays be performed?
I recommend monitoring monthly during active treatment to determine if the current treatment is effective and continuing to be effective. This is a way to identify treatment resistance early.

top10-badgeI recommend monitoring every three months during the first two years after completing treatment or for patients with advanced receiving ongoing treatments. (For example advanced breast cancer patients receiving hormonal treatments, immunotherapy treatments, checkpoint inhibitor treatments or chemotherapy treatments over long periods of time.)

For long term survivors I recommend monitoring every 6 months until the 10 year No Evidence of Disease anniversary.

This is the same schedule of monitoring that we use in the OUTSMART CANCER® System to follow measurable biomarkers in the tumor microenvironment.

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.

Ferrie S, Webster A, Wu B, Tan C, Carey S. Gastrointestinal surgery and the gut microbiome: a systematic literature review. Eur J Clin Nutr. 2021 Jan;75(1):12-25. doi: 10.1038/s41430-020-0681-9. Epub 2020 Jul 13. PMID: 32661352.

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.

Lederer, A. K., Pisarski, P., Kousoulas, L., Fichtner-Feigl, S., Hess, C., & Huber, R. (2017). Postoperative changes of the microbiome: are surgical complications related to the gut flora? A systematic review. BMC surgery, 17(1), 125. https://doi.org/10.1186/s12893-017-0325-8

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.

Vitamin-D

Higher Vitamin D Intake Reduces Risk of Colorectal Cancer

In a recent (2021) study* investigators concluded that higher total vitamin D intake is associated with decreased risks of
young-onset colorectal cancer and precursors (polyps).

colorectal-cancer
Colorectal Cancer (CRC) infographic for education
Colorectal Cancer (CRC) infographic for education illustration


Excluding skin cancers, colorectal cancer is the third most common cancer diagnosed in both men and women in the United States. The rate of people being diagnosed with colon or rectal cancer each year has dropped overall since the mid-1980s, mainly because more people are getting screened (colonoscopy) and changing their lifestyle-related risk factors (healthy BMI, decreasing red meats, refined foods, and increasing fiber and phytochemicals from fruits and vegetables and whole grains).

From 2013 to 2017, incidence rates dropped by about 1% each year. But this downward trend is mostly in older adults and masks rising incidence among younger adults since at least the mid-1990s. From 2012 through 2016, it increased every year by 2% in people younger than 50 and 1% in people 50 to 64. 
https://www.cancer.org/cancer/colon-rectal-cancer/about/key-statistics.html

During the period from 1991 to 2015 the researchers* documented 111 cases of young-onset colorectal cancer and 3,317 colorectal polyps. Analysis showed that higher total vitamin D intake was associated with a significantly reduced risk of early-onset colorectal cancer. The same link was found between higher vitamin D intake and risk of colon polyps detected before age 50.

According to principal researcher K Ng, “Our results further support that vitamin D may be important in younger adults for health and possibly colorectal cancer prevention,”

Understanding risk factors that are associated with young-onset colorectal cancer leads to informed recommendations about diet and lifestyle, as well as identifying high-risk individuals to target for earlier screening.

Many cancers, including colorectal and ovarian cancers, that were historically prevalent in older age groups are increasingly being seen in younger patients. Therefore, frontline, primary care providers, particularly in a health-focused setting such as functional, integrative, naturopathic, nutritional, and oriental medicine clinics MUST include patient teaching and appropriate screening in patients under 50.

Vitamin D is both a prognostic and predictive biomarker for both well patients and patients with a diagnosis or history of cancer. It is an important modulator of immunity and cancer biology in multiple histological types of cancer including skin, prostate, breast, ovary, colon, bladder, and kidney malignancies.

With regard to the functions of Vitamin D in the tumor microenvironment, Vitamin D

  • Regulates Gene Transcription
  • Induces Growth Arrest
  • Induces Apoptosis
  • Enhances DNA Repair
  • Enhances Antioxidant Protection
  • Enhances Immune Modulation
  • Enhances Differentiation
  • Decreases Pro-Inflammatory Cytokines
  • Decreases Invasion into the Extracellular matrix
  • Decreases Angiogenesis & Metastasis

I recommend including Serum 25-OH Vitamin D assays for ALL patients. Aim for Optimized Serum 25-OH Vitamin D levels of 60-80 ng/ml for promoting a robust cancer terrain that is inhospitable to the development, progression, and spread of cancer. Oral Vitamin D should be administered as Vitamin D3 cholecalciferol (not ergocalciferol, Vitamin D2).

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.

CRP/Albumin Ratio (GPS_Glasgow Prognostic Score)

  • Albumin-300x281-1A combination of Albumin and C-reactive protein (CRP) measurements into a 3level predictive score. 
  • Patients who had both a serum elevation of CRP (>1.0 mg/dL) and hypoalbuminemia (<3.5 g/dL) were allocated a GPS of 2. 
  • Patients with only one of the abnormal values were allocated a GPS of 1, and 
  • Patients who had neither were allocated a GPS of 0. 
  • Survival decreases with increasing score

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

  • Patient on anticoagulant medications
  • Patients with thrombocytopenia and known hypo-coagultion clotting disorders
  • Pre and Post Surgical patients (72 hours)
  • Patients with seafood allergies

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. 

MRI-Man

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.

(NB: I have no financial relationship whatsoever with  Prenuvo.)
