Highlights

Nutritional supplements like Isoquercitrin 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 Isoquercitrin 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 Isoquercitrin supplements can benefit cancer patients with Rhabdomyosarcoma on Everolimus treatment. But avoid Isoquercitrin supplements if on Ibrutinib treatment for Waldenstrom Macroglobulinemia (Relapsed Refractory). Similarly, taking nutritional supplement Isoquercitrin can benefit healthy individuals who are at genetic risk of cancer due to mutation of gene TP53. But avoid taking nutritional supplement Isoquercitrin 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 Isoquercitrin 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 Isoquercitrin based on individual context and conditions. 

Isoquercitrin Supplements for Cancer Treatment and genetic Risk

So the question is should you take the supplement Isoquercitrin? 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 TP53? Should you take it when diagnosed with Waldenstrom Macroglobulinemia (Relapsed Refractory)? Should you take Isoquercitrin supplements when diagnosed with Rhabdomyosarcoma? Should you take it when on Ibrutinib treatment? Should you continue taking Isoquercitrin supplements if you change your treatment from Ibrutinib to Everolimus? So a general explanation like – it is natural or it increases immunity may not be acceptable and sufficient for choosing Isoquercitrin. 

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 Waldenstrom Macroglobulinemia (Relapsed Refractory) or Rhabdomyosarcoma, 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 Isoquercitrin.

So the question is that are all genetic mutation risks and types of cancers to be considered as one when deciding the use of Isoquercitrin? Are the biochemical pathway implications of genetic risk for cancer due to mutation of gene TERT the same as due to mutation of gene TP53? Are the implications of taking Isoquercitrin supplements in Waldenstrom Macroglobulinemia (Relapsed Refractory) the same as Rhabdomyosarcoma? Is it one and the same if you are on treatment Ibrutinib or on Everolimus? 

Isoquercitrin – A Nutritional Supplement

Isoquercitrin is a natural flavonoid found in many foods. Isoquercitrin is also available in the form of dietary supplements. Following are some of the purported uses/benefits of isoquercitrin supplements (Cheryl A.Hobbs et al, Food and Chemical Toxicology.,2018)

  • May have anti-inflammatory properties
  • May have antioxidant properties
  • May help reduce depression
  • May help reduce blood sugar
  • May help reduce bad cholesterol
  • May have antiviral properties

Isoquercitrin is an active ingredient found in various food items. Black Tea, Green Tea and Black Chokeberry contain Isoquercitrin at different concentration levels along with other active ingredients. The molecular pathways which are regulated by Isoquercitrin include NFKB Signaling, PI3K-AKT-MTOR Signaling, Apoptosis, G-protein-coupled Receptor Signaling and Adherens junction. 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 Isoquercitrin individually or in combination is an important decision to be made. When making decisions on the use of supplement Isoquercitrin for cancer – do consider all these factors and explanations. Because just as true for cancer treatments – Isoquercitrin use cannot be a one-size-fits-all decision for all types of cancers.

Choosing Isoquercitrin Supplements for Your Cancer

The reason there is no easy way to answer the question “When should I avoid Isoquercitrin for Cancer” is because “It Depends!”. Just like the same treatment does not work for every cancer patient, based on your individual context the Isoquercitrin 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 Isoquercitrin should be avoided or not and why.

1. Will Isoquercitrin Supplements benefit Cancer Patients with Waldenstrom Macroglobulinemia (Relapsed Refractory) undergoing Ibrutinib treatment?

Waldenstrom Macroglobulinemia (Relapsed Refractory) is characterized and driven by specific genetic mutations like BTK and TBL1XR1 leading to biochemical pathway changes in NFKB Signaling, B Cell Receptor Signaling and Phospholipase Signaling. A cancer treatment like Ibrutinib 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, Isoquercitrin should be avoided for Waldenstrom Macroglobulinemia (Relapsed Refractory) along with treatment Ibrutinib. Isoquercitrin impacts pathways/processes like NFKB Signaling which either promote drivers of the disease and/or nullify 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), age, gender, BMI, lifestyle and any genetic mutation information (if available).

2. Will Isoquercitrin Supplements benefit Cancer Patients with Rhabdomyosarcoma undergoing Everolimus Treatment?

Rhabdomyosarcoma is characterized and driven by specific genetic mutations like NRAS and FGFR4 leading to biochemical pathway changes in PI3K-AKT-MTOR Signaling, Adherens junction, Epithelial to Mesenchymal Transition, RAS-RAF Signaling and MAPK Signaling. A cancer treatment like Everolimus 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, Isoquercitrin supplement should be considered for Rhabdomyosarcoma along with treatment Everolimus. Isoquercitrin supplement impacts pathways/processes like PI3K-AKT-MTOR Signaling and Adherens junction which either obstruct drivers of Rhabdomyosarcoma and/or improve Everolimus 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 Isoquercitrin 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 Apoptosis, RUNX Signaling, Stem Cell Signaling, Cell Cycle Checkpoints and JAK-STAT Signaling to get impacted. These pathways are direct or indirect drivers of cancer molecular endpoints. Isoquercitrin should be avoided when the genetic panel identifies mutation of TERT for Hematological Cancer. Isoquercitrin impacts pathways/processes like Apoptosis and RUNX Signaling and creates adverse effects with TERT and related conditions.

4. Are Isoquercitrin Supplements Safe for Healthy Individuals with TP53 Mutation Associated Genetic Risk?

TP53 is one of the genes available in panels for cancer risk testing. TP53 mutation causes biochemical pathways/processes like PI3K-AKT-MTOR Signaling, P53 Signaling, Stem Cell Signaling, Cell Cycle Checkpoints and TGFB Signaling to get impacted. These pathways are direct or indirect drivers of cancer molecular endpoints. Consider taking Isoquercitrin supplement when the genetic panel identifies mutation in TP53 for Breast Cancer and Lung Cancer. Isoquercitrin impacts pathways/processes like PI3K-AKT-MTOR Signaling and P53 Signaling and creates a supportive effect in those with TP53 mutation and related conditions.
