Highlights

Nutritional supplements like Stevia have many health benefits and are being widely used by cancer patients and those at-genetic-risk of cancer. But, is it safe to take Stevia supplements for all types of cancer and without considering any ongoing treatments and other lifestyle conditions? A common belief but only a myth is that anything natural can only benefit me or do no harm. As one example, the use of grapefruit with certain medications is not recommended. Another example, the use of spinach with some blood thinning medications can cause adverse interactions and should be avoided. For cancer, nutrition which includes the food and natural supplements has been shown to influence outcomes. Hence a frequently asked question by cancer patients to dieticians and doctors is “What Should I eat and What Should I Avoid?”. 

Taking nutritional Stevia supplements can benefit cancer patients with Diffuse Large B-Cell Lymphoma (DLBCL-Relapsed Refractory) on Prednisone treatment. But avoid Stevia supplements if on Procarbazine treatment for ATRX +ve Diffuse Glioma. Similarly, taking nutritional supplement Stevia can benefit healthy individuals who are at genetic risk of cancer due to mutation of the gene CDKN1B. But avoid taking nutritional supplement Stevia when at genetic risk of cancer due to mutation of gene TERT.

The takeaway being – your individual context will influence your decision if nutritional supplement Stevia is safe or not. And also that this decision needs to be constantly revisited as conditions change. Conditions like cancer type, current ongoing treatments and supplements, age, gender, weight, height, lifestyle and any genetic mutations identified matter. So a legitimate question for you to ask for any recommendation of food and natural supplement is how it is related to your individual context. 



Brief Overview

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. The difference being foods contain more than one active ingredient at lower diffused concentrations. Remember that each of these ingredients has its own science and biological mechanism at molecular level – hence choose  the right combination of supplements like Stevia based on individual context and conditions. 

Stevia Supplements for Cancer Treatment and Genetic Risk

So the question is should you take the supplement Stevia? Should you take it when at genetic risk of cancer for mutation of gene TERT? Should you take it when at genetic risk of cancer for mutation of gene CDKN1B? Should you take it when diagnosed with ATRX +ve Diffuse Glioma? Should you take Stevia supplement when diagnosed with Diffuse Large B-Cell Lymphoma (DLBCL-Relapsed Refractory)? Should you take it when on Procarbazine treatment? Should you continue taking Stevia supplements if you change your treatment from Procarbazine to Prednisone? So a general explanation like – it is natural or it increases immunity may not be acceptable and sufficient for choosing Stevia. 

Cancer

Cancer remains an unsolved problem statement. The improved availability of personalized treatments and monitoring of cancer via blood and saliva have been significant factors to improve outcomes. The earlier the intervention – the better the influence on outcome. Genetic testing has the potential to assess cancer risk and susceptibility early. But besides regular monitoring in most cases there are no therapeutic intervention options available. After diagnosis with cancer such as ATRX +ve Diffuse Glioma or Diffuse Large B-Cell Lymphoma (DLBCL-Relapsed Refractory), 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 next steps. A large majority of cancer patients and those at-risk do take nutritional supplements like Stevia.

So the question is that are all genetic mutation risks and types of cancers to be considered as one when deciding the use of Stevia? Are the biochemical pathway implications of genetic risk for cancer due to mutation of gene TERT the same as due to mutation of gene CDKN1B? Are the implications of taking Stevia supplements in ATRX +ve Diffuse Glioma the same as Diffuse Large B-Cell Lymphoma (DLBCL-Relapsed Refractory)? Is it one and the same if you are on treatment Procarbazine or on Prednisone? 

Stevia – A Nutritional Supplement

Stevia rebaudiana (Stevia) is a herb and its extract is commonly used as a natural zero calorie sweetener – as a sugar substitute. Steviol glycosides are the sweet tasting compounds present in Stevia. Following are some of the potential health benefits of Stevia :

Stevia supplements contain many active ingredients including Beta-bourbonene, Calamenene, Cosmosiin, Humulene, Linalool, Nerolidol and Quercitrin at different concentration levels. The molecular pathways which are regulated by Stevia include Oxidative Stress, Epithelial to Mesenchymal Transition, Cytokine Signaling, Cell Cycle and NFKB Signaling. These cellular pathways directly or indirectly regulate specific cancer molecular endpoints like growth, spread and death. Because of this biological regulation – for cancer nutrition, the right choice of supplements like Stevia individually or in combination is an important decision to be made. When making decisions on the use of supplement Stevia for cancer – do consider all these factors and explanations. Because just as true for cancer treatments – Stevia use cannot be a one-size-fits-all decision for all types of cancers.

Choosing Stevia Supplements for Your Cancer

The reason there is no easy way to answer the question “When should I avoid Stevia for Cancer” is because “It Depends!”. Just like the same treatment does not work for every cancer patient, based on your individual context the Stevia may be harmful or safe. Along with which cancer and associated genetics – the ongoing treatments, supplements, lifestyle habits, BMI and allergies are all factors deciding if Stevia should be avoided or not and why.

1. Will Stevia Supplements benefit Cancer Patients with ATRX +ve Diffuse Glioma undergoing Procarbazine treatment?

ATRX +ve Diffuse Glioma is characterized and driven by specific genetic mutations like ATRX and IDH1 leading to biochemical pathway changes in Oxidative Stress, Hypoxia, Cancer Epigenetics and Carbohydrate Metabolism. A cancer treatment like Procarbazine 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, Stevia should be avoided for ATRX +ve Diffuse Glioma along with treatment Procarbazine. Stevia impacts pathways/processes like Oxidative Stress which either promote drivers of the disease and/or nullify the treatment effect. Additionally, Stevia supplements contain many active ingredients like Humulene, Linalool, Nerolidol and Quercitrin which have one or more CYP (drug metabolizing enzyme) interactions such as CYP3A4, CYP3A5, CYP2B6, and CYP1A1 with Procarbazine treatment and hence should be avoided by patients undergoing this treatment. (Linh Thuy Nguyen et al, Chem Biol Interact., 2017; Yejin Lee et al, Chem Biol Interact., 2018; Alena Špičáková et al, Molecules., 2017; Amit Chaudhary et al, Toxicology., 2006; Pius S Fasinu et al, Front Oncol., 2019; C Rodriguez-Antona and M Ingelman-Sundberg, Oncogene., 2006) Some of the factors which should be considered when choosing nutrition are type of cancer, treatments and supplements being taken currently (if any), age, gender, BMI, lifestyle and any genetic mutation information (if available).

2. Will Stevia Supplements benefit Cancer Patients with Diffuse Large B-Cell Lymphoma (DLBCL-Relapsed Refractory) undergoing Prednisone Treatment?

Diffuse Large B-Cell Lymphoma (DLBCL-Relapsed Refractory) is characterized and driven by specific genetic mutations like CREBBP and KMT2D leading to biochemical pathway changes in Epithelial to Mesenchymal Transition, NFKB Signaling, MAPK Signaling, PI3K-AKT-MTOR Signaling and MYC Signaling. A cancer treatment like Prednisone 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 has a compatible effect to the treatment or reduces the overlap should be considered. As an example, Stevia supplements should be considered for Diffuse Large B-Cell Lymphoma (DLBCL-Relapsed Refractory) along with treatment Prednisone. Stevia supplement impacts pathways/processes like Epithelial to Mesenchymal Transition and NFKB Signaling which either obstruct drivers of DLBCL (Relapsed Refractory) and/or improve Prednisone treatment effect.

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. Are Stevia Supplements Safe for Healthy Individuals with TERT 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. TERT is one of the genes generally available in panels for cancer risk testing. 

TERT mutation causes biochemical pathways/processes like Cytokine Signaling, MYC Signaling, Nucleotide metabolism, Stem Cell Signaling and Hypoxia to get impacted. These pathways are direct or indirect drivers of cancer molecular endpoints. Stevia should be avoided when the genetic panel identifies mutation of TERT for Hematological Cancer. Stevia impacts pathways/processes like Cytokine Signaling and MYC Signaling and creates adverse effects with TERT and related conditions.

4. Are Stevia Supplements Safe for Healthy Individuals with CDKN1B Mutation Associated Genetic Risk?

CDKN1B is one of the genes available in panels for cancer risk testing. CDKN1B mutation causes biochemical pathways/processes like Cell Cycle, PI3K-AKT-MTOR Signaling, Stem Cell Signaling, FOXO Signaling and Cell Cycle Checkpoints to get impacted. These pathways are direct or indirect drivers of cancer molecular endpoints. Consider taking Stevia supplements when the genetic panel identifies mutations in CDKN1B for Neuroendocrine Cancer. Stevia impacts the pathways/processes like Cell Cycle and PI3K-AKT-MTOR Signaling and creates a supportive effect in those with CDKN1B mutation and related conditions.
