Highlights

Nutritional supplements like Horseradish 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 Horseradish 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 Horseradish supplements can benefit Early T Cell Precursor Acute Lymphoblastic Leukemia patients on Nelarabine cancer treatment. But avoid Horseradish supplements if on Cytarabine treatment for Myeloproliferative Neoplasms. Similarly, taking nutritional supplement Horseradish can benefit healthy individuals who are at genetic risk of cancer due to mutation of the gene CDKN1B. But avoid taking nutritional supplement Horseradish when at genetic risk of cancer due to mutation of gene BAP1.

The takeaway being – your individual context will influence your decision if nutritional supplement Horseradish 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 Horseradish based on individual context and conditions. 

Horseradish Supplements for Cancer Treatment and Genetic Risk

So the question is should you take the supplement Horseradish? Should you take it when at genetic risk of cancer for mutation of gene BAP1? Should you take it when at genetic risk of cancer for mutation of gene CDKN1B? Should you take it when diagnosed with Myeloproliferative Neoplasms? Should you take it when diagnosed with Early T Cell Precursor Acute Lymphoblastic Leukemia? Should you take it when on Cytarabine treatment? Should you continue taking Horseradish supplement if you change your treatment from Cytarabine to Nelarabine? So a general explanation like – it is natural or it increases immunity may not be acceptable and sufficient for choosing Horseradish. 

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 Myeloproliferative Neoplasms or Early T Cell Precursor Acute Lymphoblastic Leukemia, 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 Horseradish.

So the question is that are all genetic mutation risks and types of cancers to be considered as one when deciding the use of Horseradish? Are the biochemical pathway implications of genetic risk for cancer due to mutation of gene BAP1 the same as due to mutation of gene CDKN1B? Are the implications of Myeloproliferative Neoplasms same as Early T Cell Precursor Acute Lymphoblastic Leukemia? Is it one and the same if you are on treatment with Cytarabine or on Nelarabine? 

Horseradish – A Nutritional Supplement

Horseradish is a root vegetable belonging to the Brassicaceae family, which includes vegetables like broccoli, cabbage, mustard and radish. It has a pungent odor and taste. However, its root is odorless until its cell walls are damaged. During cell wall damage, Horseradish releases an enzyme which can convert the odorless sinigrin to allyl isothiocyanate or mustard oil. Horseradish is known to have antibacterial effects and may improve breathing problems. However, excess use of horseradish supplements can cause side-effects such as 

  • Vomiting blood
  • Diarrhea
  • Gastrointestinal disorders
  • Irritation of mucous membranes
  • Irritation of the urinary tract

Horseradish supplements contain many active ingredients including Linoleic Acid, Linolenic Acid, Kaempferol, Quercetin and Benzyl Isothiocyanate at different concentration levels. The molecular pathways which are regulated by Horseradish include NFKB Signaling, PI3K-AKT-MTOR Signaling, Stem Cell Signaling, FOXO Signaling and MYC 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 Horseradish individually or in combination is an important decision to be made. When making decisions on the use of supplement Horseradish for cancer – do consider all these factors and explanations. Because just as true for cancer treatments – Horseradish use cannot be a one-size-fits-all decision for all types of cancers.

Choosing Horseradish Supplements for Your Cancer

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

1. Will Horseradish Supplements benefit Cancer Patients with Myeloproliferative Neoplasms undergoing Cytarabine treatment?

Myeloproliferative Neoplasms is characterized and driven by specific genetic mutations like JAK2 and CALR leading to biochemical pathway changes in NFKB Signaling, MYC Signaling, MAPK Signaling, JAK-STAT Signaling and Cytokine Signaling. A cancer treatment like Cytarabine 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, Horseradish should be avoided for Myeloproliferative Neoplasms along with treatment Cytarabine. Horseradish impacts pathways/processes like NFKB Signaling and MYC Signaling which either promote drivers of the disease and/or nullify the treatment effect. Additionally, Horseradish supplements contain active ingredients like Linoleic Acid, Linolenic Acid, Kaempferol, Quercetin and Benzyl Isothiocyanate which have CYP3A4 interactions with Cytarabine treatment, and hence should be avoided by cancer patients undergoing this treatment. (Ji-Won Park et al, Chin J Nat Med, 2019; Hsien-Tsung Yao et al, Life Sci., 2006; Linda B von Weymarn et al, Carcinogenesis., 2006Fang-fang Zhang et al, Zhejiang Da Xue Xue Bao Yi Xue Ban., 2006; Dawn E Colburn et al, Hematology., 2004) 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 Horseradish Supplements benefit Cancer Patients with Early T Cell Precursor Acute Lymphoblastic Leukemia undergoing Nelarabine Treatment?

Early T Cell Precursor Acute Lymphoblastic Leukemia is characterized and driven by specific genetic mutations like CDKN2A and JAK3 leading to biochemical pathway changes in PI3K-AKT-MTOR Signaling, MAPK Signaling, JAK-STAT Signaling, Cell Cycle and RAS-RAF Signaling. A cancer treatment like Nelarabine 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, Horseradish supplement should be considered for Early T Cell Precursor Acute Lymphoblastic Leukemia along with Nelarabine treatment . Horseradish supplement impacts pathways/processes like PI3K-AKT-MTOR Signaling and MAPK Signaling which either obstruct drivers of the disease and/or improve Nelarabine 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 Horseradish Supplements Safe for Healthy Individuals with BAP1 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. BAP1 is one of the genes generally available in panels for cancer risk testing.

BAP1 mutation causes biochemical pathways Stem Cell Signaling, Angiogenesis, MAPK Signaling and DNA Repair to get impacted. These pathways are direct or indirect drivers of cancer molecular endpoints. Horseradish should be avoided when the genetic panel identifies mutation of BAP1 for Skin Cancer and Cholangiocarcinoma. Horseradish impacts pathways/processes like Stem Cell Signaling and Angiogenesis and creates adverse effects with BAP1 and related conditions.

4. Are Horseradish 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 FOXO Signaling, Cell Cycle, Stem Cell Signaling, PI3K-AKT-MTOR Signaling and Cell Cycle Checkpoints to get impacted. These pathways are direct or indirect drivers of cancer molecular endpoints. Consider taking Horseradish supplements when the genetic panel identifies mutation in CDKN1B for Neuroendocrine Cancer. Horseradish impacts pathways/processes like FOXO Signaling and Cell Cycle and creates a supportive effect with CDKN1B mutation and related conditions.
