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 Duodenal Adenocarcinoma when undergoing chemotherapy or when you determine you have a genetic risk for developing Duodenal Adenocarcinoma because of CTNNB1 and KRAS 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 Duodenal Adenocarcinoma 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 Peach” or “Include fruit Nance in my diet” or “Should I reduce consumption of vegetable Yam” or “Can I take Birch and Dim 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 DUODENAL ADENOCARCINOMA, TREATMENTS, GENETIC INFORMATION, AND OTHER CONDITIONS.
The overall objective of personalized nutrition for Duodenal Adenocarcinoma 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 DUODENAL ADENOCARCINOMA, WHEN TREATMENTS, DISEASE STATUS AND OTHER CONDITIONS CHANGE.
About Duodenal Adenocarcinoma
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 Duodenal Adenocarcinoma from cBioPortal. The patients enrolled in the studies for Duodenal Adenocarcinoma are in ages between 34 to 90 with an average age of 60. 64.5% of males and 35.5% of females were the distribution of gender in these clinical studies. From a patient sample size of 121; the top genes with mutations and other abnormalities for Duodenal Adenocarcinoma include genes KRAS, TP53, DNMT3A, KMT2D and CTNNB1. The occurrence frequency distribution for these genes respectively is 26.7%, 22.2%, 13.3%, 11.1% and 11.1%. These tumor genetic details of Duodenal Adenocarcinoma are mapped to molecular biochemical pathway drivers of cancer thereby providing definition of characteristic features of Duodenal Adenocarcinoma.
Adenocarcinoma duodenal is a type of cancer that affects the duodenum, the first part of the small intestine. Duodenal adenocarcinoma affects the cells that produce the chemicals and enzymes that help with the digestion of the food. Duodenal adenocarcinoma is often diagnosed in later stages due to the lack of symptoms in the early stages. As the tumor grows, it may block proper digestion and cause symptoms of nausea, abdominal pain, or constipation. Most duodenal adenocarcinomas affect older adults in the age group of 60-80 years of age. Conditions such as celiac disease or Crohn’s disease can increase the risk of duodenal adenocarcinoma, in addition to life-style habits such as smoking, alcohol and eating a high-salt diet. The staging of duodenal adenocarcinoma is crucial for determining the appropriate treatment plan and prognosis. Stage 4 duodenal adenocarcinoma is considered the most advanced stage and often results in the cancer having spread to distant parts of the body. Effective management of duodenal adenocarcinoma requires a multi-disciplinary approach, including surgery, chemotherapy, and radiation therapy, along with careful monitoring and follow-up. Outlook for duodenal adenocarcinoma is better when detected in early stages. Optimal nutrition (foods and natural supplements) along with the treatment and monitoring can help improve the patient’s well-being.

Significance of Nutrition for Duodenal Adenocarcinoma
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 Duodenal Adenocarcinoma. 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 Peach includes active ingredients Beta-sitosterol, Modified Citrus Pectin, Oleic Acid, Linolenic Acid, Vitamin C and others. And Nance contains active ingredients Vitamin C, Betulin, Vitamin A 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 Duodenal Adenocarcinoma, activation or inhibition of selected biochemical pathways like Cell Cycle, RUNX 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 Duodenal Adenocarcinoma, 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 DUODENAL ADENOCARCINOMA – CONSIDER HIGH QUANTITY ACTIVE INGREDIENTS CONTAINED IN FOODS.
Foods for Duodenal Adenocarcinoma undergoing chemotherapy treatment
In Duodenal Adenocarcinoma – the genes KRAS, TP53, DNMT3A, KMT2D and CTNNB1 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 Duodenal Adenocarcinoma are Cell Cycle, RUNX Signaling, Notch Signaling and others. Cisplatin 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, RUNX Signaling, Notch 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.

Foods for Genetic Risk of Duodenal Adenocarcinoma
One of the ways to assess risk of cancer is by checking for presence of genetic abnormalities in a set of genes. There is prior information on a list of genes whose mutations and other aberrations can play a role in risk to different cancers. CTNNB1 and KRAS are two genes whose abnormalities are risk factors for Duodenal Adenocarcinoma. In such a cancer risk situation – while there are typically no treatments which a physician can prescribe – the various biochemical pathways which are potentially molecular drivers of Duodenal Adenocarcinoma can be used as a guide for coming up with a recommended personalized nutrition plan. For Duodenal Adenocarcinoma gene CTNNB1 has causative impact on biological pathways like Adherens junction, Androgen Signaling and Cytoskeletal Dynamics. And KRAS has a causative impact on biological pathways like G-protein-coupled Receptor Signaling, Growth Factor Signaling and Immune Evasion Signaling. Foods and nutritional supplements which have molecular action to cancel out biochemical pathways effects of genes like CTNNB1 and KRAS should be included in a personalized nutrition plan. And those foods and supplements which promote the effects of genes CTNNB1 and KRAS should be avoided.
