Nutritional supplements and extracts like Vitamin A have benefits and are used by cancer patients and those at-genetic risk of cancer. There is limited or hardly any clinical data available for use of nutritional supplements and foods in cancer patients. Generating clinical evidence of efficacy for cancer through a randomized clinical trial is further infeasible due to variations in genetics and cancer chemotherapy treatments across cancer patients. Hence a different and new approach is needed to find out for which cancers you should not take Vitamin A supplement and why should not take them?
Is it okay to take Vitamin A extracts or supplements for all cancer indications and any chemotherapy treatment? A common belief but a myth is that everything natural can only be of benefit and do no harm. For example, the use of grapefruit with certain medications is not recommended. Another example is the use of spinach with some blood thinning medications can cause adverse interactions and hence to be avoided. For cancer, nutrition including plant-based foods and supplements can influence outcomes and hence an extremely important decision which needs to be made. Hence NIH-National Cancer Institute has a website for nutrition for cancer care for patients which are generalized recommendations and not personalized for cancer indication and treatments.
A frequently asked question by cancer patients and those at-risk is “What Foods and Nutritional Supplements could be beneficial over others for me?”. “Who should not take an extract or supplement and why?”. Generic guidelines like eating only plant-based-foods or avoiding all sugar or adopting a keto diet is a good start but not actionable and personalized enough.
To find answers to questions on extracts and nutritional supplements and foods requires knowledge of contained active ingredients; genetic mutation prevalence for cancer indication; understanding of underlying cancer biology; chemotherapy treatments and mechanism of actions of active ingredients.
Taking Vitamin A extracts or nutritional supplements may benefit Primary Penile Squamous Cell Carcinoma patients on Cisplatin treatment over Cranesbill nutritional supplements. But Vitamin A supplements or Vitamin A extracts offer less benefit if on Lenalidomide treatment for Primary Monoclonal gammopathy of undetermined significance compared to Rosmarinic Acid. Similarly, taking nutritional supplements Vitamin A may benefit healthy individuals who are at genetic risk of cancer due to mutation of gene MYC over Sumac. But avoid nutritional supplements Vitamin A when at genetic risk of cancer due to mutation of gene ERBB2.
The takeaway being – cancer, genomics, treatments and other personalized factors will influence decision making to questions like: Are extracts or nutritional supplements Vitamin A beneficial and should not be taken? Why should Vitamin A be not taken? Who should not take Vitamin A? What are side effects of Vitamin A with Lenalidomide chemotherapy? What are the benefits of Vitamin A for cancer? Can Vitamin A help fight cancer and so on.
Whenever there are changes in chemotherapy treatments or cancer tissue genetics – the nutrition may change and hence needs to be re-evaluated. Do consider factors like cancer indication, ongoing chemotherapy treatments and nutritional supplements, age, gender, weight, height, lifestyle and genetics for personalization of nutrition.
Use of nutritional supplements – vitamins, herbs, minerals, probiotics, and other specialty categories are increasing. Supplements are high concentrations of active ingredients which are also found in different foods. Difference between supplements and foods being that foods contain more than one active ingredient at much lower concentrations. Every active ingredient in an extract or nutritional supplement or food has a unique mechanism of action which can influence nutrition decisions.
These are some example questions which nutrition planning should help answer for you. Should you take supplements Vitamin A? Should you take it when at genetic risk of cancer for mutation of gene MYC? Should you take it when at genetic risk of cancer for mutation of gene ERBB2? Should you take it when diagnosed with Primary Monoclonal gammopathy of undetermined significance? Should you take it when diagnosed with Primary Penile Squamous Cell Carcinoma? Should you take it when on Cisplatin treatment? Should you continue taking it if you change your treatment from Cisplatin to Lenalidomide? So a general explanation like – it is organic and plant-based or it increases immunity is not sufficient information for making a decision of use of Vitamin A extracts and nutritional supplements.
Genetic variations across cancer patients can be different and hence no two cancers are alike. The improved availability of “personalized to genetics” chemotherapy treatments and cancer disease monitoring via blood and saliva have been significant factors to improve outcomes. The earlier the lifestyle and treatment intervention – the better the influence on outcome. Genetic testing has the potential to assess cancer risk and susceptibility early. But for at-risk individuals besides regular monitoring in most cases there are no therapeutic treatment intervention options available. After diagnosis with cancer such as Primary Penile Squamous Cell Carcinoma or Primary Monoclonal gammopathy of undetermined significance, the treatments get personalized to tumor genomics and factors like staging of disease, age and gender. During cancer remission (after treatment cycle is complete) – monitoring is used for assessment of any relapse and accordingly decide on next steps. A large majority of cancer patients and those at-risk may take nutritional supplements like Vitamin A.
So the question is that are all genetic risks and cancer indications to be considered uniformly when making decisions on the use of Vitamin A extracts or nutritional supplements? Are the biochemical pathway implications of genetic risk for cancer due to mutation of gene MYC the same as due to mutation of gene ERBB2? Are the implications of Primary Penile Squamous Cell Carcinoma the same as Primary Monoclonal gammopathy of undetermined significance? Is it one and the same if you are on treatment with Lenalidomide or Cisplatin?
Vitamin A – An Extract or Nutritional Supplement
Vitamin A supplements contain many active ingredients including Vitamin A at different concentration levels. The molecular pathways which are regulated by Vitamin A include Cell Cycle, PI3K-AKT-MTOR Signaling and Stem Cell Signaling. These biochemical pathways directly or indirectly regulate specific cancer molecular endpoints like growth, spread and death of cancer cells. Because of this biological regulation – for cancer nutrition, the right choice of supplements like Vitamin A individually or in combination is an important decision to be made. When making decisions on the use of supplement Vitamin A over other nutritional supplements – do consider all these factors.
Who Should not take Vitamin A Supplements and Why?
There is no easy way to answer the question “For which cancers should I not chooseVitamin A nutritional supplements”. Just like the same chemotherapy treatment does not work across patients, for similar reasons Vitamin A in comparison with other nutritional supplements may be beneficial or not. Along with which cancer and associated genetics – the ongoing treatments, lifestyle habits, height, weight and food allergies are all factors in deciding if Vitamin A should be avoided or not and why.
1. Will Vitamin A Supplements benefit Primary Monoclonal gammopathy of undetermined significance patients undergoing Lenalidomide treatment?
Primary Monoclonal gammopathy of undetermined significance is characterized and driven by specific genetic mutations like LATS2, ZMYM2 and CDK8 leading to biochemical pathway changes in PI3K-AKT-MTOR Signaling and Hippo Signaling. A cancer treatment like Lenalidomide works through a specific pathway mechanism of action. The goal is to have a good overlap between the treatment and cancer driving pathways for a personalized approach which is effective. In such a condition any food or nutritional supplement which has a contrary effect to the treatment or reduces the overlap should be avoided. As an example, Vitamin A supplement should not be taken for Primary Monoclonal gammopathy of undetermined significance along with treatment Lenalidomide. Vitamin A supplement impacts the biochemical pathway called PI3K-AKT-MTOR Signaling which either promotes drivers of the disease and/or nullifies the treatment effect. Some of the factors which should be considered when choosing nutrition are type of cancer, treatments and supplements being taken currently (if any
2. Will Vitamin A Supplements benefit Primary Penile Squamous Cell Carcinoma Patients undergoing Cisplatin Treatment?
Primary Penile Squamous Cell Carcinoma is characterized and driven by specific genetic mutations like ABRAXAS1, PIK3CB and NUP93 leading to biochemical pathway changes in Cell Cycle, Hematopoiesis and Inositol Phosphate Signaling. A cancer treatment like Cisplatin works through specific pathway mechanisms. The goal is to have a good overlap between the treatment and cancer driving pathways for a personalized approach. In such a condition any food or nutritional supplement which supports treatment action or improves the overlap should be considered. As an example, Vitamin A supplements should be considered for Primary Penile Squamous Cell Carcinoma along with the treatment Cisplatin. Vitamin A supplement impacts pathways/processes like Cell Cycle which either obstruct drivers of Primary Penile Squamous Cell Carcinoma and/or improve Cisplatin treatment effect.
Foods to Eat After Cancer Diagnosis!
No two cancers are the same. Go beyond the common nutrition guidelines for everyone and make personalized decisions about food and supplements with confidence.
3. What about Vitamin A Supplements for Healthy Individuals with ERBB2 Mutation associated Genetic Risk?
Different companies offer panels of genes to be tested for assessing genetic risk to different cancers. These panels cover genes associated with cancers of the breast, ovary, uterus, prostate, and gastrointestinal system and others. Genetic testing of these genes may confirm a diagnosis and help guide treatment and management decisions. Identification of a disease-causing variant may also guide testing and diagnosis of at-risk relatives. ERBB2 is one of the genes generally available in panels for cancer risk testing.
ERBB2 mutation causes biochemical pathways/processes like Growth Factor Signaling and PI3K-AKT-MTOR Signaling to get impacted. These pathways are direct or indirect drivers of cancer molecular endpoints. Vitamin A should not be taken when the genetic panel identifies mutation of ERBB2 for Esophageal Adenocarcinoma. Vitamin A impacts pathways/processes like PI3K-AKT-MTOR Signaling and creates adverse conditions with ERBB2.
4. What about Vitamin A Supplements for Healthy Individuals with MYC Mutation associated Genetic Risk?
MYC is one of the genes available in panels for cancer risk testing. MYC mutation causes biochemical pathways/processes like Stem Cell Signaling, Antigen Presentation, PI3K-AKT-MTOR Signaling and Amino Acid Metabolism to get impacted. These pathways are direct or indirect drivers of cancer molecular endpoints. Vitamin A supplements may be considered when the genetic panel identifies mutations in MYC for Burkitt Lymphoma. Vitamin A impacts pathways/processes like Stem Cell Signaling and creates a canceling effect in those individuals with MYC mutation.
* Other Factors are also included like BMI, Treatments, Lifestyle Habits
It is important to remember that cancer chemotherapy treatments and nutrition are never the same for everyone. Food and nutritional supplements like Vitamin A are chosen by you and can influence outcomes.
