# Nutrition in neuroblastoma and DIPG
Nutritional status and treatment
In children with neuroblastoma and DIPG, nutrition plays a central role during treatment.
ProveniIncluded in official guidelines, or approved by EMA or FDA
Good nutritional status helps the body fight the disease better and respond better to intensive therapies such as chemotherapy, radiation and stem cell transplantation.
ResearchediPositive results in clinical studies, not yet standard treatment
Research shows that the way children are fed after an autologous stem cell transplant (for example by mouth versus through a feeding tube) affects recovery and outcomes. This is an important point of attention for the treatment team, as intensive chemotherapy often impairs the ability to eat normally.
Many children experience eating problems during treatment due to nausea, mouth pain, fatigue or changed taste. A dietitian specializing in pediatric oncology can help adjust nutrition and ensure the child still receives enough calories and nutrients.
Special attention during certain treatments
Some medications used for neuroblastoma can have interactions with food.
ProveniIncluded in official guidelines, or approved by EMA or FDA
These interactions are important to know about, as they can affect how the medication works or how it is digested. The treatment team will communicate about this concretely, but it is good to have these conversations.
Also, certain foods may be harder to tolerate during chemotherapy. This varies greatly from child to child. A dietitian can help with practical tips for food that is well tolerated.
Oxidative stress and protective substances in food
ResearchediPositive results in clinical studies, not yet standard treatment
Scientific research is focusing on natural substances in food that may offer protection against oxidative stress – damage that can be caused both by the cancer itself and by some treatments. This research includes phenolic compounds from plant-based food and isoflavones from soy.
ExperimentaliOngoing in study setting, outcome still unknown
These findings are still largely in the laboratory stage. There is still no clear evidence that eating certain foods with these substances directly improves cancer treatment or prognosis in children with neuroblastoma. Furthermore, extra intake of certain substances through supplements may be risky for children undergoing treatment.
This is not a reason to avoid healthy, colorful vegetables and fruit – these can be part of normal nutrition. But targeted supplementation or special 'miracle diets' based on this are not recommended and should first be discussed with your treatment team.
Nutrition and the nervous system
ResearchediPositive results in clinical studies, not yet standard treatment
There is interest in how certain nutritional components can support nervous system health. This is particularly relevant because DIPG is a tumor in the brainstem area, and because some treatments can have consequences for the nervous system.
ExperimentaliOngoing in study setting, outcome still unknown
Research into neuroprotection (protection of nerve cells) through nutrition or extracts is still largely experimental. This also applies to soy-derived preparations and polysaccharide-rich extracts that are being studied. For children with DIPG or neuroblastoma, there is no practical nutritional protocol based on this yet.
The focus in practice remains on normal nutrition, easy to take, with sufficient energy and building blocks.
Nutrition after treatment
ProveniIncluded in official guidelines, or approved by EMA or FDA
Good recovery after intensive cancer treatment requires continued attention to nutrition. Some children have long-term digestive problems or taste disorders.
ResearchediPositive results in clinical studies, not yet standard treatment
For children who have undergone stem cell transplantation, the way they are fed (for example, early resumption of eating by mouth where possible) appears to work out favorably. This underscores the importance of targeted nutritional care that fits with what the child can tolerate.
Regular contact with a dietitian can help gradually return nutrition to normal patterns, according to what the child tolerates.
What your child can eat and drink
ProveniIncluded in official guidelines, or approved by EMA or FDA
Hygiene around food is particularly important during chemotherapy and around stem cell transplantation, because the immune system is weakened then. The treatment team provides clear guidelines here.
Food doesn't need to be 'special' or 'pure' – ordinary, clean food that the child likes and can manage is the goal. Many children develop strong preferences and aversions to certain foods, and that is normal.
UnproveniNo scientific evidence that it works
There is no evidence that certain eating patterns ('organic', 'pure', 'detox', or very restricted diets) help children with cancer better. On the contrary: overly restrictive food can cause malnutrition, which is counterproductive.
Usual food allergies must of course be avoided. For intolerances or phobias that develop during treatment, a dietitian can help.
Practical support with nutrition problems
Many children undergoing chemotherapy eat less or eat poorly. This can lead to weight loss and reduced nutritional status. A dietitian can help by:
- Offering food in small, frequent portions
- Choosing foods that are well tolerated
- Addressing taste disorders and nausea
- If necessary, introducing food via alternative routes (feeding tube, intravenous)
ProveniIncluded in official guidelines, or approved by EMA or FDA
This supportive nutritional care improves treatment outcomes and helps the child come through intense therapy stronger.
Every child is different. What works well for one child may not suit another. That is why personal guidance from the treatment team and a dietitian is essential.
