Highlights

Nutritional supplements like Docosahexaenoic Acid (DHA) 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 Docosahexaenoic Acid (DHA) 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 Docosahexaenoic Acid (DHA) supplements can benefit Renal Non-Clear Cell Carcinoma patients on Bevacizumab treatment. But avoid Docosahexaenoic Acid (DHA) supplements if on Ifosfamide treatment for Choroid Plexus Tumors. Similarly, taking nutritional supplement Docosahexaenoic Acid (DHA) can benefit healthy individuals who are at genetic risk of cancer due to mutation of gene TP53. 

The takeaway being – your individual context will influence your decision if nutritional supplement Docosahexaenoic Acid (DHA) 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 Docosahexaenoic Acid (DHA) based on individual context and conditions. 

Docosahexaenoic Acid (DHA) Supplements for Cancer Treatment and Genetic Risk

So the question is should you take the supplement Docosahexaenoic Acid (DHA)? Should you take it when at genetic risk of cancer for mutation of gene TP53? Should you take it when diagnosed with Choroid Plexus Tumors? Should you take it when diagnosed with Renal Non-Clear Cell Carcinoma? Should you take it when on Ifosfamide treatment? Should you continue taking it if you change your treatment from Ifosfamide to Bevacizumab? So a general explanation like – it is natural or it increases immunity may not be acceptable and sufficient for choosing Docosahexaenoic Acid (DHA). 

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 Choroid Plexus Tumors or Renal Non-Clear Cell Carcinoma, 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 Docosahexaenoic Acid (DHA).

So the question is that are all genetic mutation risks and types of cancers to be considered as one when deciding the use of Docosahexaenoic Acid (DHA)? Are the implications of Choroid Plexus Tumors same as Renal Non-Clear Cell Carcinoma? Is it one and the same if you are on treatment Ifosfamide or on Bevacizumab? 

Docosahexaenoic Acid (DHA) – A Nutritional Supplement

Docosahexaenoic Acid (DHA) is an omega-3 fatty acid commonly found in fishes and other seafoods. It helps boost brain health, improve heart functioning, and is essential for the growth and functional development of the brain during pregnancy. DHA may also have benefits in improving other health conditions such as diabetes, thrombosis, high blood pressure, arthritis, myocardial infarction and depression. (L A Horrocks and Y K Yeo, Pharmacol Res., 1999)

The molecular pathways which are regulated by Docosahexaenoic Acid (DHA) include Cell Cycle Checkpoints and PI3K-AKT-MTOR 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 Docosahexaenoic Acid (DHA) individually or in combination is an important decision to be made. When making decisions on the use of supplement Docosahexaenoic Acid (DHA) for cancer – do consider all these factors and explanations. Because just as true for cancer treatments – Docosahexaenoic Acid (DHA) use cannot be a one-size-fits-all decision for all types of cancers.

Choosing Docosahexaenoic Acid (DHA) Supplements for Your Cancer

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

1. Will Docosahexaenoic Acid (DHA) Supplements benefit Cancer Patients with Choroid Plexus Tumors undergoing Ifosfamide treatment?

Choroid Plexus Tumors is characterized and driven by specific genetic mutations like TERT and TP53 leading to specific biochemical pathway changes. A cancer treatment like Ifosfamide 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, Docosahexaenoic Acid (DHA) should be avoided for Choroid Plexus Tumors along with treatment of Ifosfamide. Docosahexaenoic Acid (DHA) impacts specific pathways 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 Docosahexaenoic Acid (DHA) Supplements benefit Cancer Patients with Renal Non-Clear Cell Carcinoma undergoing Bevacizumab Treatment?

Renal Non-Clear Cell Carcinoma is characterized and driven by specific genetic mutations like MUC16 and TP53 leading to specific biochemical pathway changes. A cancer treatment like Bevacizumab 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, Docosahexaenoic Acid (DHA) supplements should be considered for Renal Non-Clear Cell Carcinoma along with treatment Bevacizumab. Docosahexaenoic Acid (DHA) supplements impact specific pathways which either obstruct drivers of Renal Non-Clear Cell Carcinoma and/or improve Bevacizumab 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 Docosahexaenoic Acid (DHA) Supplements Safe for Healthy Individuals with TP53 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.

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