Wilms Tumor and Other Childhood Kidney Tumors Treatment (PDQ®): Treatment - Patient Information [NCI] - Stages of Wilms Tumor and Other Childhood Kidney Tumors
In stage III, cancer remains in the abdomen after surgery and at least one of the following is true:
- Cancer spread to lymph nodes in the abdomen or pelvis (the part of the body between the hips).
- Cancer spread to or through the surface of the peritoneum (the layer of tissue that lines the abdominal cavity and covers most organs in the abdomen).
- Chemotherapy was given before surgery and a biopsy of the tumor was done during surgery to remove it.
- The tumor broke open before or during surgery to remove it.
- The tumor was removed in more than one piece.
In stage IV, cancer has spread through the blood to organs such as the lungs, liver, bone, or brain, or to lymph nodes outside of the abdomen and pelvis.
Stage V and those at high risk of developing Wilms tumor
In stage V, cancer cells are found in both kidneys when the disease is first diagnosed.
