What is Wilms Tumor?

  • Wilms tumor (also called nephroblastoma) is a cancerous tumor in the cells of the kidney. Wilms tumor is highly treatable. Wilms tumor can occur at any age between infancy and age 15, but is most common in children age 5 or younger. Adults rarely have Wilms tumor.

    The tumor can spread outside the kidney to the abdominal lymph nodes and lungs. With prompt and aggressive treatment, Wilms tumor is successfully treated in the majority of children. Multidisciplinary approaches, including a combination of surgery, chemotherapy, and radiation therapy can be used.

    Wilms tumor treatment at Dana-Farber/Boston Children's

    Children with Wilms Tumor receive highly coordinated multidisciplinary care through the Kidney Tumor Program at Dana-Farber/Boston Children's Cancer and Blood Disorders Center. As a regional, national, and international referral center, our surgeons and solid tumor oncologists have extensive expertise in the care of children with Wilms tumor, particularly those with bilateral tumors (tumors on both sides of the abdomen), large tumors, or "unfavorable" tumor subtypes that are rarely seen elsewhere. Our multidisciplinary team, which draws on specialists from across Dana-Farber Cancer Institute and Boston Children's Hospital, works in concert to develop thoughtful and precise treatment plans.
