Wilms Tumor Survival Rates

Survival rates are estimates used by doctors to discuss the prognosis or outlook for cancer recovery. The 4-year survival rate is a common measure used to assess the prognosis of Wilms tumors. This rate represents the percentage of children who survive at least 4 years after their initial cancer diagnosis.

For instance, a 4-year survival rate of 80% indicates that an estimated 80 out of 100 children diagnosed with that specific cancer are still alive 4 years post-diagnosis. It is important to note that many children live significantly longer than 4 years, and a considerable number are ultimately cured. To calculate 4-year survival rates, doctors must analyze data from children who were treated at least 4 years prior. Advancements in treatment since then may lead to an improved prognosis for children currently being diagnosed with Wilms tumors.

For Wilms Tumors, Cancer Staging is important to determine the survival rate:

Stage IThe tumor is contained in a single kidney, removed completely with surgery; the renal capsule was intact; the cancer did not grow into blood vessels surrounding the kidney; and the tumor was not biopsied before removal.
Stage IIThe tumor has grown beyond the kidney into nearby tissue or blood vessels, but was completely removed by surgery without any apparent cancer left behind. Nearby lymph nodes did not contain cancer and no tumor biopsy was necessary. 
Stage IIIWilms tumors that likely have not been completely removed, with the remaining cancer limited to the abdomen. This stage may involve various features, such as:Cancer spreading to nearby lymph nodes;Tumor growing into vital structures;Tumor implants in the abdominal lining;Cancer cells at the surgical sample's edge;Cancer cell spillage during surgery;Tumor removal in multiple pieces; or A pre-surgery tumor biopsy.
Stage IVThe cancer has spread through the blood to organs distant from the kidneys, such as the lungs, liver, brain, or bones, or to far away lymph nodes.
Stage VTumors are found in both kidneys at the time of diagnosis.

Combined with histological characterizations, the following are the current 4-year relative survival rates for Wilms Tumors estimated by the American Cancer Society:

It is important to consider the following when interpreting these numbers:

  • These numbers only apply to the stages when the cancer was first diagnosed, not when the cancer grows, spread, or returns after treatment
  • These numbers do not take into account your overall health, genetics, personal circumstances, and treatment response. Those details can affect your survival and recovery outlook.
  • Treatments have improved over time and people today have a better outlook for recovery than people diagnosed in the past.
  • If cancer is caught early, you can expect a better survival and recovery rate. There can be a great difference between relative survival rates when the diagnosis is at the localized stage versus the regional and advanced stages.

Wilms Tumors have a generally positive prognosis and can be caught and dealt with early using modern testing methods and treatments. What's important is to be aware of any genetic conditions that your child may have which could increase the risk of Wilms tumor development in early childhood. If your child has these risks you need to inform your doctor immediately, so that regular screenings with ultrasounds and other necessary imaging tests may be conducted. 

If Wilms tumors are found early, the likelihood of successful treatment and recovery is very high. But if it is found late, even with successful treatment, your child may incur developmental problems that could make adult life difficult. Worse, they may require a kidney transplant and frequent dialysis. If you believe that your loved one was misdiagnosed, or diagnosed late with Wilms tumor, and is now suffering from pain and a decreased survival outlook in the State of New York, call the Porter Law Group.

Doctors have a responsibility to provide adequate care and promptly examine all possible options thoroughly with their patients. If not, they could be guilty of medical negligence.

There are three types of negligence:

Incorrect diagnosis

This is when a medical provider diagnoses a cancer patient with a disease other than cancer. This results in a patient not only losing resources for undergoing the wrong treatments but also in a delay in the necessary cancer treatment, which actively worsens the condition.

Delayed diagnosis

This is when a healthcare provider fails to diagnose cancer in its early stages. It can lead to the patient requiring more intense treatment options. It not only increases the cost but like with the common radiation therapy, subjects the patient to more pain and potential side effects that would have been unnecessary had the cancer been detected earlier.

False positive diagnosis

This is when a patient who does not have cancer is improperly diagnosed with cancer. This can lead to a patient undergoing surgery and radiation therapy. These are both costly and potentially life-threatening treatments, especially when they didn’t even have the disease to begin with.

If you or a loved one believe your healthcare provider misdiagnosed or delayed your small intestine cancer diagnosis, you may be entitled to financial compensation for your pain, discomfort, and decreased chances of survival.
