Highlights
No two cancers are the same, nor are they treated the same, and neither should nutrition be the same for everyone. Nutrition includes foods like pulses, vegetables, fruits, nuts, oils, herbs and spices. Also nutrition includes supplements which are high concentrations of foods or high concentrations of individual ingredients found in foods. For cancers like Paget Disease Of The Breast when undergoing chemotherapy or when you determine you have a genetic risk for developing Paget Disease Of The Breast because of APOB and MTR gene mutations, a very important question is “What foods should I avoid and what foods are recommended specifically for me?”. The other related question is “What nutritional supplements should I avoid?”.
There is no one answer to this question for cancers such as Paget Disease Of The Breast which can be found through internet searches. The answer to the question is “It Depends” because the nutrition plan needs to be personalized for you. Nutrition should depend on the cancer indication, genetic information, adult or pediatric, staging, primary or secondary, advanced, metastatic, relapsed or refractory, ongoing treatments if any, nutritional supplements being taken, age and factors like gender, weight, height, lifestyle, allergies and food preferences.
In short – the process to answer questions like “Should I Avoid eating fruit Quince” or “Include fruit Mulberry in my diet” or “Should I reduce consumption of vegetable Spinach” or “Can I take Mulberry and Birch supplements” is not as simple as internet searches. The process is very complex and answers are based on knowhow of genetics, action of treatments, active ingredients in foods and their associated biological action. Finally the answer to the nutrition question needs to be personalized for you.
RECOMMENDATION: PERSONALIZE YOUR FOODS AND SUPPLEMENTS TO PAGET DISEASE OF THE BREAST, TREATMENTS, GENETIC INFORMATION, AND OTHER CONDITIONS.
The overall objective of personalized nutrition for Paget Disease Of The Breast is to minimize foods and nutritional supplements which have adverse interactions with cancer molecular drivers and ongoing treatments. And identify those foods and supplements which have a beneficial action. Whenever there are changes in treatments or diagnosis – it is important to remember that your foods and supplements need re-evaluation. And the answers to the nutrition question could be different based on the new context.
RECOMMENDATION: UPDATE YOUR NUTRITION FOR PAGET DISEASE OF THE BREAST, WHEN TREATMENTS, DISEASE STATUS AND OTHER CONDITIONS CHANGE.
About Paget Disease Of The Breast
cBioPortal is one source of collection of cancer patient data from clinical trials across 350 plus cancer indications. The data from each clinical trial includes the clinical trial name and study details like number of patients, ages, gender, ethnicity, treatments, tumor site, genetic aberrations found and analysis of all the data. The cBioPortal for Cancer Genomics was originally developed at Memorial Sloan Kettering Cancer Center (MSK). The public cBioPortal site is hosted by the Center for Molecular Oncology at MSK – https://www.cbioportal.org/about.
Following key highlights are derived from clinical data for Paget Disease Of The Breast from cBioPortal. The top genes with mutations and other abnormalities for Paget Disease Of The Breast include genes KMT2C, APOB, MTR, BRWD1 and ARID2. The occurrence frequency distribution for these genes respectively is 34.0%, 24.0%, 20.0%, 20.0% and 17.0%. These tumor genetic details of Paget Disease Of The Breast are mapped to molecular biochemical pathway drivers of cancer thereby providing definition of characteristic features of Paget Disease Of The Breast.
Paget’s disease of the breast is a rare cancer, accounting for only 1-3% cases of female breast cancer. It mainly affects post-menopausal women, and occurrence in men is an extremely rare finding. It is a malignant disease that presents itself as eroding and bleeding ulcer of the nipple, starting with eczema-like changes including itching, scaling, and crusting, and discharge. Paget’s disease represents an extension of a ductal breast adenocarcinoma. The 5-year recurrence free survial of paget’s disease of the breast is 75-90% with ductal carcinoma in situ (DCIS) and 63-75% with invasive carcinoma. Treatment of Paget’s disease involves surgery followed by adjuvant therapy that may include radiation therapy, chemotherapy, or hormone therapy, appropriately supported by right nutrition (foods and natural supplements) aligned to the treatment context.

Significance of Nutrition for Paget Disease Of The Breast
All foods and nutritional supplements consist of a collection of one or more active chemical ingredients in different proportions and quantities. The action of some active ingredients in a food can have adverse interactions while other active ingredients in the same food may be supportive from the context of Paget Disease Of The Breast. Hence the same food has good and not-so-good actions and analysis of combined effect will be needed to come up with a personalized nutrition plan.
For example Quince includes active ingredients Vitamin C, Oleic Acid, Quercitrin, Chlorogenic Acid, Modified Citrus Pectin and others. And Mulberry contains active ingredients Resveratrol, Morusin and others. It is likely that some of these active ingredients of the same food could have opposing effects and hence it is recommended to identify recommended foods based on analysis of all high quantity ingredients contained in foods.
For cancers like Paget Disease Of The Breast, activation or inhibition of selected biochemical pathways like Cell Cycle Checkpoints, Growth Factor Signaling, PI3K-AKT-MTOR Signaling, MAPK Signaling plays an important role in driving cancer growth. Similarly different treatments work via different molecular actions which should never be canceled out by your foods and supplements. The foods and nutritional supplements contain different active ingredients each of which have a specific molecular action on different biochemical pathways. Hence, eating some foods and nutritional supplements would be recommended with a specific treatment of Paget Disease Of The Breast, while eating some other foods and supplements may not be recommended.
One common mistake when finding foods to eat or not – is to consider only a few active ingredients contained in foods based on internet searches and ignore the rest. Because different active ingredients contained in foods may have opposing effects on relevant biochemical pathways – it is recommended to consider all the high quantity active ingredients that are present in significant and much larger than trace amounts in the food.

RECOMMENDATION: TO FIND RECOMMENDED AND NON-RECOMMENDED FOODS FOR PAGET DISEASE OF THE BREAST – CONSIDER HIGH QUANTITY ACTIVE INGREDIENTS CONTAINED IN FOODS.
Foods for Paget Disease Of The Breast undergoing chemotherapy treatment
In Paget Disease Of The Breast – the genes KMT2C, APOB, MTR, BRWD1 and ARID2 have high occurrences of genomic abnormalities. Not all of these genes necessarily are relevant for cancer – though they have been reported. Some of these genes directly or indirectly end up manipulating different cancer related biochemical biological pathways. Some of the pathways which are relevant drivers for Paget Disease Of The Breast are Cell Cycle Checkpoints, Growth Factor Signaling, PI3K-AKT-MTOR Signaling and others. Letrozole is one of the chemotherapies used for cancer treatment. The intent of treatment is to negate or cancel out effects of biochemical pathway drivers Cell Cycle Checkpoints, Growth Factor Signaling, PI3K-AKT-MTOR Signaling so as to reduce disease progression and inhibit growth. Those foods whose combined action of active ingredients support treatment action and do not enhance disease drivers are recommended foods and supplements which will be included in personalized nutrition. And similarly – those foods whose combined action of active ingredients is not supportive of treatment action but end up promoting disease drives will not be recommended in your personalized nutrition plan.
RECOMMENDATION: AVOID SUPPLEMENTS AND FOODS WHICH ARE NOT SUPPORTIVE OF CANCER TREATMENT ACTION AND RATHER ENHANCE DISEASE DRIVERS.
