Does Stress Cause Cancer?

 

Lifestyle Factors That Impact Breast Cancer Risk

cancer-and-stress

  • Alcohol:  Drinking Alcohol Increases Risk of Breast Cancer
  • Weight and Body Composition: Excess body fat increases risk for post-menopausal breast cancer. Lean muscle, low body fat decreases risk of pre-menopausal breast cancers
  • Physical Activity: Sedentary behavior is linked to increased risk of breast cancer, while being active decreases the risk of breast cancer 

Vigorous activity decreases the risk for pre-menopausal breast cancer.

Moderate activity decreases risk for post-menopausal breast cancer.

Some evidence indicates that people who are physically active (both before and after diagnosis) have a greater chance of surviving breast cancer.

  • Breastfeeding: Reduces risk of both pre- and post-menopausal breast cancer
  • Sleep: Women who report sleeping less than 5 hours per night  before diagnosis have an increased risk of dying from breast cancer compared to women whose  pre-diagnosis sleep pattern was 7-8 hours per night.  Women who have disrupted circadian rhythms due to night shift work have an increased risk of breast cancer.

Does Stress Cause Cancer?

Maladaptive and ongoing responses to stress mediated by the Autonomic Nervous System and Hypothalamic Pituitary Axis promote a tumor microenvironment that favors inflammation, oxidative stress, poor glycemic control, carcinogenesis, proliferation, angiogenesis and metastasis

Physiological Pathways, Bio-behavioural Processes and Oncogenesis:

  • Environmental and social processes activate interpretive processes in the central nervous system (CNS) that can subsequently trigger fight-or-flight stress responses in the autonomic nervous system (ANS) or defeat/withdrawal responses through the activation of the hypothalamic–pituitary–adrenal axis (HPA)
  • Individual differences in perception and evaluation of external events (coping) creates variability in individual ANS and HPA activity levels.
  • Over long periods of time, these neuroendocrine dynamics can alter various physiological processes involved in tumorigenesis, including oxidative metabolism, DNA repair, oncogene expression by viruses and somatic cells, and production of growth factors and other regulators of cell growth.
  • Once a tumour is initiated, neuroendocrine factors can also regulate the activity of proteases, angiogenic factors, chemokines and adhesion molecules involved in invasion, metastasis and other aspects of tumour progression.
  • CNS processes can also shape behavioural processes that govern cancer risk (for example, smoking, transmission of oncogenic viruses or exposure to genotoxic compounds).


Integrated Model of Bio-behavioral Influences on Cancer Pathogenesis Through Neuro-Endocrine Pathways

chart

In this model, bio-behavioural factors such as life stress, psychological processes and health behaviours (blue panel) influence tumour-related processes (green panel) through the neuroendocrine regulation of hormones, including adrenaline, noradrenaline and glucocorticoids (red panel). 

Central control of peripheral endocrine function also allows social, environmental and behavioural processes to interact with biological risk factors such as genetic background, carcinogens and viral infections to systemically modulate malignant potential (red panel). 

Direct pathways of influence include effects of catecholamines and glucocorticoids on tumour-cell expression of genes that control cell proliferation, invasion, angiogenesis, metastasis and immune evasion (green panel). 

Stress-responsive neuroendocrine mediators can also influence malignant potential indirectly through their effects on oncogenic viruses and the cellular immune system (red panel). 

These pleiotropic hormonal influences induce a mutually reinforcing system of cellular signals that collectively support the initiation and progression of malignant cell growth (green panel). 

Furthermore, neuroendocrine deregulation can influence the response to conventional therapies such as surgery, chemotherapy and immunotherapy (green panel). 

In addition to explaining bio-behavioural risk factors for cancer, this model suggests novel targets for pharmacological or behavioural intervention.

green tea extracts

Green Tea Extract Reduces Severity of Radiation-Induced Dermatitis

Breast cancer is the most common cancer affecting women worldwide. Radiation dermatitis affects nearly all women receiving radiotherapy for breast cancer.  new-breast-cancer

RID may result in less tolerance to treatment and even discontinuation of treatment. The patient may have skin changes ranging from faint erythema (reddening) and desquamation (peeling skin) to skin necrosis (death of skin cells) and ulceration, depending on the severity of the reaction.  Several studies demonstrate that topical green tea extract may be an effective prophylactic treatment.  

To make a strong hot water extract:  Place 8 tea bags of organic green tea into 1 cup of filtered or distilled water. Bring to a boil and simmer covered for 20 minutes. Place extract into sterile glass dropper bottle. (Available at most pharmacies).   Spray skin liberally before and after radiotherapy treatment.

The National Cancer Institute (USA) has developed 4 criteria for the classification of acute radiation dermatitis:

  • Grade 1 – Faint erythema or desquamation.
  • Grade 2 – Moderate to brisk erythema or patchy, moist desquamation confined to skin folds and creases. Moderate swelling.
  • Grade 3 – Confluent, moist desquamation greater than 1.5 cm diameter, which is not confined to the skin folds. Pitting oedema (severe swelling).
  • Grade 4 – Skin necrosis or ulceration of full-thickness dermis (middle layer of skin).

Epigallocatechin-3-gallate ameliorates radiation-induced acute skin damage in breast cancer patients undergoing adjuvant radiotherapy

In a study using topical Epigallocatechin-3-gallate forty nine patients topical EGCG was applied daily during radiotherapy treatment.  “Topical EGCG was applied daily, starting when grade I dermatitis appeared and ending two weeks after radiotherapy. The maximum dermatitis observed during the EGCG treatment was as follows: Grade 1 toxicity, 71.4% (35 patients); grade 2 toxicity, 28.6% (14 patients); there were no patients with grade 3 or 4 toxicity. The majority of the radiation-induced dermatitis was observed 1 week after the end of radiotherapy. EGCG reduced the pain in 85.7% of patients, burning-feeling in 89.8%, itching in 87.8%, pulling in 71.4%, and tenderness in 79.6%.”

Efficacy of Epigallocatechin-3-Gallate in Preventing Dermatitis in Patients With Breast Cancer Receiving Postoperative Radiotherapy: A Double-Blind, Placebo-Controlled, Phase 2 Randomized Clinical Trial 

A total of 180 eligible patients were enrolled, of whom 165 (EGCG, n = 111; placebo, n = 54) were evaluable for efficacy (median [range] age, 46 [26-67] years). The occurrence of grade 2 or worse RID was significantly lower (50.5%; 95% CI, 41.2%-59.8%) in the EGCG group than in the placebo group (72.2%; 95% CI, 60.3%-84.1%) (P = .008). The mean RIDI in the EGCG group was significantly lower than that in the placebo group. Furthermore, symptom indexes were significantly lower in patients receiving EGCG. Four patients (3.6%) had adverse events related to the EGCG treatment, including grade 1 pricking skin sensation (3 [2.7%]) and pruritus (1 [0.9%]).

Prophylactic use of EGCG solution significantly reduced the incidence and severity of RID in patients receiving adjuvant radiotherapy for breast cancer.

The effects of tea extracts on proinflammatory signaling

Tea extracts supported the restitution of skin integrity. 

Tea extracts inhibited proteasome function and suppressed cytokine release. 

NF-kappaB activity was altered by tea extracts in a complex, caspase-dependent manner, which differed from the effects of epigallocatechin-gallate. 

Additionally, both tea extracts, as well as epigallocatechin-gallate, slightly protected macrophages from ionizing radiation

All Cancers Linked to Environmental Toxins

Making Environmental Health A Part of Health Care

Each month of the year is devoted to awareness of one or more cancers. September is devoted to multiple cancers.  

What do all of these cancers have in common?

There is an increasing volume of compelling evidence linking all types of cancer to environmental exposures.

Our knowledge of mechanisms linking exposures of toxicants to specific cancers is also increasing.  

environmental-pollution

There are two reasons that we as clinicians and care providers must be aware of the many contributing offenders and how to identify, assess, mitigate risk and safely remove body burden or toxicants in our patients.

Additionally, it is my practice to engage in patient education and patient teaching on the first or second visit to increase patient and family awareness about the importance of taking control of and reducing their toxic exposures as many toxicants are ubiquitous our homes, workplaces and communities.  Many toxicants include the use of common everyday products.    I also refer patients to these very reliable and up to date websites:  Environmental Working Group where foods, cleaning supplies, garden supplies are rated and their secondary site  Skin Deep Cosmetics Database for self-care and baby care products, including safe sunscreens.  They also have many downloadable publications for patients including 12 Hormone-Altering Chemicals and How to Avoid Them

Taking a good “ toxic exposures history” is important in all patients.  Of course, the very diagnostic methods and treatment modalities used in oncology are sources of toxic exposure as well!!  Many clinicians feel taking such a history from their patients will open us a Pandora’s box.

sewer-pollution

However, in the context of oncology, it is essential to do so, if only to bring awareness and to address the risk and health status not only of the patient, but also their family members.

My go to experts in this area include Dr. Walter Crinnion ND and Joseph Pizzorno, ND, both seasoned researchers and clinicians. They have recently published a well researched book  Clinical Environmental Medicine, which I consider required reading for all clinicians, especially those working with cancer patients.  There is a version for patients as well The Toxin Solution: How Hidden Poisons in the Air, Water, Food, and Products We Use Are Destroying Our Health--AND WHAT WE CAN DO TO FIX IT

The  American Academy of Environmental Medicine is an excellent resource for education and training and conferences where world-class experts convene.

Most in the patients control is their home environment and their food and water.

Fran Drescher’s Cancer Schmancer website has instructions for how to host a Detox Your Home Party.   

The first step is avoidance, avoidance, avoidance to reduce body burden, followed by appropriate supplements to help the body deal with what is there and finally safe and appropriate cleansing and detoxification interventions. Patients must also understand how to avoid re-exposure.

green-tea-extract

Green Tea Extract Reduces Severity of Radiation Dermatitis

The use of a solution containing a green tea extract has been shown to reduce both the incidence and severity of radiation-induced dermatitis in women undergoing adjunctive radiotherapy for breast cancer. This was the conclusion of a phase 2 randomized, placebo-controlled trial by a team of Chinese researchers.

Data from the World Health Organization indicates that in 2020, there were 2.3 million women diagnosed with breast cancer. In the treatment of women with breast cancer, radiation therapy is widely used conjunction with other therapies such as surgery, chemotherapy and hormonal therapies.  A common and frequent adverse effect of radiotherapy is radiation-induced dermatitis (RID) suffered by millions of women.

green-tea

The purpose of the current  study was to investigate the safety, tolerability and preliminary effectiveness of topical epigallocatechin-3-gallate (EGCG) for radiation dermatitis in patients with breast cancer receiving adjuvant radiotherapy.

A  solution of green tea extract  sprayed on the radiated areas of the skin reduced severity of radiation-induced dermatitis.

The Chinese team recruited women with breast cancer undergoing postoperative radiotherapy and randomized them (2:1) to receive either the green tea extract or placebo (normal saline solution).  These solutions were sprayed to the whole of the radiation field from the first day of therapy until two weeks after completion of treatment. 

A total of 165 women with a median age of 46 years were enrolled and randomized to EGCG, the primary catechin found in green tea or placebo.

The onset of radio-dermatitis was delayed by 2-3 weeks and the intensity and severity of the symptoms were significantly decreased in the treated group.  No skin toxicity was observed.

The authors concluded that prophylactic use of a green tea extract significantly reduced both the incidence and severity of RID and that it has the potential to become a new choice for skin care in women receiving radiotherapy.

Topical green tea extract supports restoration of skin integrity and control of inflammatory cytokines and oxidative stress in the skin. Green tea extract also reduces the acute skin-induced reactions including pain and sensations of burning, itching, pulling and tenderness.

Dr. Chilkov: Practical Application:

green-tea-leavesTopical Green Tea Extract Spray

To make a medicinal water extract: Place 8 organic green tea bags into a 16 oz glass jar or glass container.  Pour boiling water over the tea bags, cover immediately and steep for one hour.   After it has cooled to room temperature store covered in the refrigerator.  When ready to use transfer water extract to a a glass spray bottle.  Apply liberally to the radiation field before and after each radiotherapy session and three times daily for 3 weeks after the last radiotherapy session.  

Fresh Aloe Vera Gel poultice

Areas where skin is most impacted can be covered with. mashed fresh aloe vera gel and covered with a large gauze bandage.   This can easily be held in place underneath a sports bra or leotard or similar.  Apply fresh aloe gel twice daily. Allow to be in contact with the skin for several hours or overnight.  If you do not have access to a live aloe vera plant or fresh aloe gel you can use alcohol free aloe vera juice or aloe vera gel commonly found in natural foods stores.    Aloe Vera is the botanical of choice for repair of radiation damaged skin.

Topical Calendula Oil (not extract) is also a soothing topical anti-inflammatory agent for radiation induced dermatitis.  If the skin is very damaged, saturate a 4x4” gauze square and place over the affected area.

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.

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.

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).

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.

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.
