Understanding Neuroblastoma

Neuroblastoma is a children’s cancer diagnosed in approximately 500 to 1,000 children per year in the USA. Neuroblastoma is a complex tumor of the sympathetic nervous system, a condition that has been known for 35 years. Its frequency is second only to brain tumors and it is seldom seen in children over 14 years old.

The median age for tumor discovery is two years, and it occurs somewhat more in boys than girls. Like most cancers, its cause is unknown. It is extremely difficult to diagnose in small children, and once diagnosed, its progression is often rapid, and very painful. Although neuroblastoma accounts for only 8% of all cancers, it is responsible for over 15% of the deaths.

The disease is diagnosed from stage I (a localized tumor confined to one organ or area of organ) to stage IV (solid tumors that have spread to several organs or parts of the body). Depending on the stage of the disease, treatment may be limited to tumor removal surgery, or may be as extensive as tumor removal surgery combined with chemotherapy, radiation, and bone marrow transplants.

In most cases, children with neuroblastoma are not diagnosed until Stage IV, when, until recently, long-term survival rates stood at a dismal 20% or less. However, encouraging developments in treatment and research are helping children to be diagnosed earlier, and to have increased chances of survival.   Below is a list links regarding Neuroblastoma:

Diagnosis of Neuroblastoma

The two most important factors in the prognosis for a child with neuroblastoma are the stage of the disease and the age of the child at the time of diagnosis. For all stages, infants less than one year old have a much better chance for remission and survival than older children. Early diagnosis is one of our best weapons in the war against neuroblastoma.  Often, neuroblastoma is first discovered when parents or a physician feel a mass or tumor somewhere in the child's body. Sometimes the child shows no outward symptoms, and sometimes symptoms resemble those of many more common childhood illnesses, such as bruising, mild flu symptoms, diarrhea, and loss of appetite.

More acute symptoms can include bone pain, hypertension, anemia, skin nodules, a pronounced limp, or a refusal to walk.  Pediatricans can order a simple, non-invasive 24 hour urine test, which is nearly 100% accurate in detecting neuroblastoma cancer. Also, ultrasound, CT scans, and MRI scans can effectively detect neuroblastoma-related tumors.

Treatment

The treatment of neuroblastoma depends on the age of the child, the size and position of the tumour, the tumour biology, and whether the neuroblastoma has spread.

Surgery

For tumours that have not spread (localised tumours), the treatment is usually surgery. If the tumour is at an early stage and there is no evidence that it has spread to the lymph nodes or other parts of the body, an operation to remove the tumour, or as much of it as possible, will be done.In children with localised tumours, a cure is usually possible. However, if, due to the tumour biology results, the tumour is classed as 'high risk', further treatment will be needed. If the tumour is initially too large to remove safely, then chemotherapy will be given to shrink it down before surgery.

Chemotherapy

If the tumour has already spread by the time of diagnosis, or is indicated as being high risk by the tumour biology result, intensive chemotherapy is needed. Chemotherapy is the use of anti-cancer (cytotoxic) drugs to destroy cancer cells. It is usually given as injections and drips (infusions) into a vein. Your child's specialist will discuss with you the type and amount of chemotherapy needed.

High dose chemotherapy with stem-cell rescue

If the neuroblastoma has spread to several parts of the body, or is high risk, high-dose chemotherapy with stem cell rescue is used.

High doses of chemotherapy 'wipe out' the body's bone marrow (where blood cells are made). To prevent the problems that this causes, stem cells (blood cells at their earliest stages of development) are collected from your child through a drip, before the chemotherapy is given. They are then frozen and stored. After the chemotherapy, the stem cells are given back to your child (again through a drip). The stem cells make their way into the bone marrow where they grow and develop into mature blood cells.

Radiotherapy

If the neuroblastoma has spread to several parts of the body or is high risk, external radiotherapy may be given. This uses high-energy rays to destroy the cancer cells, while doing as little harm as possible to normal cells. External radiotherapy is given from a machine outside of the body. Internal radiotherapy may sometimes be given using radioactive mIBG. Radioactive mIBG is similar to the investigation used to diagnose a neuroblastoma, but uses higher doses of radioactivity to kill the cancer cells.

How to Find New Treatments!

With the sometimes overwhelming amount of information there is on the Internet about various forms of therapy, it can be difficult to determine where to begin your search. Here are some tips that you might find helpful in researching treatment options for your child.

First of all, it would be very beneficial for you to have a good understanding of the type of cancer with which your child has been diagnosed. Knowing your enemy as intimately as possible always provides you with access to more ammunition in the fight. If you are seeking out medical opinions from physicians and researchers that specialize in neuroblastoma, it is a good idea to have a copy of your child's medical reports and any relevant information you might need. Keep a record of details, beginning at diagnosis, and include information such as the following:

  • Date of diagnosis and age of your child
  • Disease stage
  • Location of primary tumour and metastases
  • Histology (ask your child's oncologist if you are unsure; can include N-myc amplification, hyperploidy, VMA/HVA ratio, NSE, serum ferritin, lactate, dehydrogenase, GD2, CD44 antigen, TRK-A protooncogene, 1p deletion)
  • Treatments used to date
  • Description of how your child tolerated therapy
  • Any short or long term side effects experienced
  • How soon after completion of therapy did relapse occur
  • Options presented by your child's oncologist

Once you have gathered together your information, you will be in a much better position to research possible treatment options.

At the clinical trials sites listed above under "Treatment", you will find lists of active clinical trials for neuroblastoma. Clinical trials are available in three phases (see the ped-onc treatment page for a description of clinical trial phases). Keep in mind that your child will have to meet certain criteria to be accepted into these studies. This is done for the protection of your child. Phase III studies show the most promise. However, Phase I and II studies are also worth considering, as they have demonstrated themselves to be potentially beneficial. If your child has recently relapsed, consider enrolling him/her into a Phase III study. If this does not provide a remission or at least stable disease, you may wish to consider a Phase II or Phase I study. The decision, at this point, is largely a personal one. Only you, together with the expert opinion of your child's oncologist, can make that determination.

Another avenue available is to contact an oncologist that specializes in neuroblastoma treatment and research. Again, it would be to your advantage to have as much medical information on your child as possible handy when making contact with one of these physicians. Provide them with a synopsis of your child's medical history, and ask them if they have any current treatments and/or suggestions as to what your next step should be. It might be a good idea to give them contact information for your child's present oncologist. Ask them if they would call your child's doctor to discuss his/her case.

Finally, it would be to your advantage if you are able to connect with other parents fighting the same battle. Experience has shown me that most parents are very knowledgeable about their child's cancer, and are very willing to help others in the same situation. Other parents can prove to be one of your greatest resources.

Side Effect's

Below is a list of information regarding side effect's.  Please know that this is gathered information from not only going through the process but also information gathered from website's regarding neuroblastoma side effects.  If you have a child in treatment rely on your parental feelings, if you feel that you need to call a physician please do this ASAP.  You are the parent and know better than anyone if something is wrong!  Thank you for visiting as always.  Feel free to email us any information you would like to share at montanashope@hotmail.com

Immediate Side Effect's

Treatment often causes side effects, and your child’s doctor will discuss this with you before the treatment starts.  Ask as many questions as possible, make a list prior to visiting the physician.  Educate yourself before you go into meet with your physician.  Discuss every possible option and if you feel uncomfortable about anyting at all please seek a second opinion.  We are not physicians ourselves, we are fighting the neuroblastoma battle as well.  You know your child better than anyone so go with your gut!  Any possible side effects will depend upon the actual treatment being given and the part of the body that is being treated. Side effects can include: feeling sick (nausea) and vomiting, hair loss, increased risk of infection, bruising and bleeding, tiredness and diarrhoea.

Late Side Effects

A small number of children may develop side effects, sometimes many years later. These include possible reduction in bone growth, fertility problems, a change in the way the heart and the kidneys work, hearing problems and a slightly increased risk of developing another cancer in later life. More detailed information about these late side effects can be found in our general information on children's cancer.

Staging

The 'stage' of a cancer is a term used to describe its size and whether it has spread beyond its original site. Knowing the particular type, and the stage, of the cancer helps the doctors to decide on the best treatment for the child.

A commonly used staging system for neuroblastoma is described below:

Stage 1
The cancer is contained within one area of the body (localised) and there is no evidence of it having spread. It can be completely removed by surgery, or there may be very small (microscopic) amounts of tumour left
 
Stage 2A
The cancer is localised and has not begun to spread, but cannot be completely removed by surgery

Stage 2B
The cancer is localised and has begun to spread into nearby lymph nodes

Stage 3
The cancer has spread into surrounding organs and structures, but has not spread to distant areas of the body

Stage 4
The cancer has spread to distant lymph nodes, bone, bone marrow, liver, skin or other organs

Stage 4S
The cancer is localised (as in stage 1, 2A or 2B) and has begun to spread to the liver, skin or to some extent the bone marrow. This is found in children under one year old.

If the cancer has spread to distant parts of the body, this is known as secondary, or metastatic cancer.

If the cancer comes back after initial treatment, this is known as recurrent cancer.
