Wilms Tumor

Wilms tumor is a type of kidney cancer that's most common in children. Kidneys are part of the body's waste removal system, called the urinary system. This system helps get rid of extra water and waste products through urine. The urinary system includes the kidneys, ureters (tubes that carry urine from the kidneys), the bladder (where urine collects), and the urethra (the tube that carries urine out of the body).

Nephroblastoma, another name for Wilms tumor, is a rare cancer that mainly affects kids. It's the most frequent type of kidney cancer found in children. Children between the ages of 3 and 4 are most likely to develop this cancer. It becomes much less common after age 5, but it can still affect older children and even adults, though much less often.

Usually, Wilms tumor develops in only one kidney. But sometimes, it affects both kidneys.

Medical understanding and treatment of Wilms tumor have improved significantly over time. Modern treatments have led to better outcomes for children with this cancer. For most children with Wilms tumor, the outlook is positive with proper treatment.

Wilms tumor, a rare childhood cancer, can show up in different ways. Sometimes, children don't have any noticeable symptoms. However, if a child does have symptoms, they might include:

• A noticeable lump or swelling in their tummy (stomach area). This might feel like a hard mass.
• Pain in their tummy.
• Other possible signs include:
  • Fever.
  • Blood in their pee (urine).
  • Low red blood cell count (anemia). This means their body isn't making enough healthy red blood cells, which can make them feel tired and weak.
  • High blood pressure.

If you notice any of these signs or anything else that worries you about your child, it's important to make an appointment with their doctor. While it's likely that the symptoms have a different cause, it's crucial to get any concerns checked out.

If you notice any health problems in your child that worry you, schedule a visit with their doctor. Wilms tumor is a rare cancer, so it's probably not the cause. However, it's crucial to have any unusual symptoms checked out by a healthcare professional. Don't hesitate to bring up any concerns you have.

Wilms tumor, a type of kidney cancer in children, has a cause that scientists don't fully understand.

Cancer happens when cells in the body have changes in their DNA. DNA is like a set of instructions for the cells, telling them what to do. These changes tell the cells to grow and multiply much faster than usual. Normal, healthy cells grow and then die as part of a natural process. But cancer cells keep growing, even when they should die. In Wilms tumor, these changes cause extra cells to grow in the kidney, forming a tumor.

Sometimes, the DNA changes that increase the risk of Wilms tumor can be passed down from parents to their children. This is not very common.

Wilms tumor is a type of kidney cancer that can affect children. Several factors can increase a child's risk of developing this cancer.

Race: In North America and Europe, Black children have a slightly higher chance of getting Wilms tumor than children of other races. Conversely, Asian-American children seem to have a lower risk. This difference in risk is not fully understood, but researchers are studying it.

Family History: If a child has a family member who had Wilms tumor, their risk of developing the disease is higher. This suggests a possible genetic link.

Birth Defects: Some children born with certain medical conditions are at higher risk for Wilms tumor.

• Aniridia: This condition means the colored part of the eye (the iris) may not develop fully or at all.
• Hemihypertrophy: With hemihypertrophy, one side of the body or a part of the body is larger than the other.

Genetic Syndromes: Wilms tumor can be part of a larger, rare group of syndromes. These are conditions that cause multiple problems across different parts of the body.

• WAGR syndrome: This syndrome is characterized by Wilms tumor, aniridia, problems with the genitals and urinary system, and potential intellectual disabilities.
• Denys-Drash syndrome: This syndrome is connected to Wilms tumor, kidney disease, and a condition where a boy's genitals might not look clearly male. This is called male pseudohermaphroditism.
• Beckwith-Wiedemann syndrome: Children with this syndrome often have a larger than average body size (macrosomia). They might also have organs in their tummy area that extend towards the umbilical cord, an unusually large tongue, large internal organs, and abnormally shaped ears.

It's important to remember that these factors increase a child's risk, but they don't guarantee that a child will develop Wilms tumor. If you have any concerns about your child's health, it's crucial to talk to a doctor.

Wilms tumor, a type of kidney cancer in children, can't be prevented. However, if a child has medical conditions that make them more likely to develop Wilms tumor, their doctor might recommend regular kidney ultrasounds. These ultrasounds use sound waves to create images of the kidneys, looking for any signs of problems. While ultrasounds can't stop Wilms tumor from happening, they can sometimes help find the cancer early, when it's easier to treat. Early detection is key because it allows doctors to start treatment sooner, which can improve the chances of a full recovery.

Sometimes, a 3D printer can be used to create a precise model of a child's body, helping doctors plan surgery for Wilms tumor, a type of kidney cancer in children.

To figure out if a child has Wilms tumor, doctors first look at the child's family history and perform several tests:

• Physical Exam: The doctor checks for any signs that might suggest Wilms tumor. This could include looking for swelling or lumps in the abdomen.

• Blood and Urine Tests: These lab tests help assess how well the kidneys are working. Problems with kidney function can sometimes be a clue.

• Imaging Tests: These tests create pictures of the kidneys. Different types of imaging, such as ultrasounds, CT scans, MRIs, and chest X-rays, can help find a kidney tumor. These tests allow doctors to see the size and location of the tumor.

Once Wilms tumor is diagnosed, the medical team may need to figure out if the cancer has spread. This is called staging the cancer.

Staging helps doctors decide on the best treatment. Staging looks for the spread of cancer beyond the original kidney.

Doctors use tests like chest X-rays, chest CT scans, and bone scans to see if the cancer has spread.

The stage of Wilms tumor helps determine the treatment plan. In the United States, Wilms tumor is staged as follows:

• Stage 1: The cancer is only in one kidney. Surgery can often remove all the cancer.

• Stage 2: The cancer has grown beyond the kidney, possibly into nearby tissues like fat or blood vessels. Surgery can still usually remove all the cancer, but sometimes additional treatments might be needed.

• Stage 3: The cancer has spread to nearby lymph nodes (small organs that fight infection) or other areas within the abdomen. Cancer cells might leak into the abdomen during surgery, or all the cancer might not be removable. Treatment options are often more complex than for stage 1 or 2.

• Stage 4: The cancer has spread beyond the kidney to other parts of the body, like the lungs, liver, bones, or brain. Treatment options are often more extensive and may include chemotherapy in addition to surgery.

• Stage 5: Cancer cells are found in both kidneys. Each kidney tumor is staged separately. This means the cancer in each kidney is looked at individually to determine the best treatment plan.

Wilms Tumor Treatment: A Guide for Families

Wilms tumor, a rare type of kidney cancer in children, is typically treated with a combination of surgery, chemotherapy, and sometimes radiation therapy. The specific treatment plan depends on how advanced the cancer is (the stage). It's often best to seek treatment at a children's cancer center with experience in treating Wilms tumor.

Surgery:

Surgery is a common first step for Wilms tumor. The goal is to remove all or part of the affected kidney. Surgery also helps confirm the diagnosis by allowing doctors to examine the tissue under a microscope to see if it's cancerous and determine the type of cancer.

Several types of surgery might be needed:

• Partial Nephrectomy: If the tumor is small, only the tumor and a small surrounding piece of the kidney might be removed. This is often done if the child has only one healthy kidney.
• Radical Nephrectomy: This involves removing the entire kidney, along with nearby lymph nodes, part of the ureter (the tube that carries urine), and sometimes the adrenal gland. This is done if the cancer is more extensive. The remaining kidney often takes over the work of both kidneys.
• Removal of Both Kidneys: In cases where the cancer affects both kidneys, doctors aim to remove as much cancer as possible. Sometimes, both kidneys need to be removed. This would require the child to have dialysis (a machine to filter blood) or a kidney transplant.

Chemotherapy:

Chemotherapy uses strong medicines to kill cancer cells throughout the body. For Wilms tumor, doctors often use a combination of these medicines. These drugs are usually given intravenously (through a vein).

Side effects of chemotherapy can vary but may include nausea, vomiting, loss of appetite, hair loss, and a higher risk of infection. Talk to your child's healthcare team about potential side effects and long-term effects that might result from treatment.

Chemotherapy can be given before surgery to shrink the tumor, making it easier to remove. It can also be used after surgery to kill any remaining cancer cells. In some cases, chemotherapy might be the only treatment option if the cancer is too advanced for surgery. If the cancer is in both kidneys, chemotherapy is often given before surgery to improve the chances of saving a kidney.

Radiation Therapy:

Radiation therapy uses high-energy beams (like X-rays or protons) to destroy cancer cells. During treatment, the child lies on a table while a machine moves around them, targeting the cancer with the beams.

Possible side effects include nausea, diarrhea, fatigue, and skin irritation similar to a sunburn. Radiation therapy might be given after surgery to eliminate any remaining cancer cells, or to control the cancer if it has spread to other parts of the body. Again, discuss potential long-term effects with your child's healthcare team.

Supporting Your Child Through Treatment:

Dealing with a child's cancer diagnosis is emotionally challenging. Here are some suggestions to help you navigate this difficult time:

• Be Present: Try to be with your child during tests and treatments. Explain what's happening in terms they understand.
• Maintain a Routine: Include play time in your child's schedule. Many hospitals have playrooms staffed by child life specialists trained to support children during treatment.
• Seek Support: Talk to hospital staff for support and guidance. Connect with support groups for parents of children with cancer. Sharing experiences with others who understand can provide a sense of community and hope.
• Managing Daily Life: After the hospital, keep track of your child's energy levels, appetite, sleep patterns, medicines, and side effects. Share this information with their doctor. Maintain a balanced diet, encouraging fluids, and good oral hygiene (with your healthcare team's guidance). Be sure to get the go-ahead from the doctor before resuming vaccinations and dental visits.
• Communicate: Talk openly with your child and other children in the family about the illness. Explain any changes you might see in your child's appearance or energy levels and address their concerns.

Helping Families Through Cancer Treatment

Dealing with a child's cancer diagnosis is incredibly challenging. This guide offers practical tips for navigating the emotional and physical aspects of treatment, both at the hospital and at home.

At the Hospital:

When your child has appointments or stays in the hospital, try to make things as comfortable and familiar as possible.

• Bring familiar items: Bring a favorite toy or book to help your child feel more at ease while waiting.
• Stay involved: If possible, stay with your child during tests and treatments. This provides comfort and support.
• Explain things clearly: Use words your child understands to describe what will happen.
• Schedule playtime: Many hospitals have playrooms staffed by trained child life specialists or recreational therapists. These professionals can help children cope with stress and provide engaging activities. If your child needs to stay in their room, ask if a specialist can visit.
• Seek support: Talk to the hospital staff. They can provide information about resources and support groups. Look for parent support groups for families facing similar challenges. These groups can offer invaluable support, hope, and practical advice from those who have been there. Ask the healthcare team about any local support groups.

At Home:

After your child leaves the hospital:

• Monitor energy levels: Pay attention to your child's energy levels and adjust their activities accordingly. Encourage regular, age-appropriate activities when they feel up to it, but make sure they get plenty of rest, especially after treatments like chemotherapy or radiation.
• Track progress: Keep a daily record of your child's temperature, energy levels, sleep patterns, medications, and any side effects. Share this information with their doctor. This helps the medical team monitor their progress and adjust treatment as needed.
• Maintain a regular diet: Maintain a balanced diet as much as possible. If your child is not eating well, try to prepare favorite foods. Chemotherapy can sometimes make eating less appealing. Encourage plenty of fluids.
• Oral care: Encourage good mouth care. A mouth rinse can help with sores or bleeding. Use lip balm to soothe any cracked lips. Ideally, your child should have a dental check-up before treatment begins. After treatment, check with their doctor before scheduling any dental visits or vaccinations. Cancer treatment can affect the immune system.
• Talking to siblings: Talk to your other children about the illness. Explain any changes they might see in their sibling, such as hair loss or low energy. Be open to listening to their concerns and questions. Let them know it's okay to express their feelings.
