  • WAGR
  • Pay special attention to features of those syndromes (WAGR syndrome and Beckwith-Wiedemann syndrome [BWS]) associated with Wilms tumor (ie, aniridia, genitourinary malformations, and signs of overgrowth). (medscape.com)
  • Children with WAGR syndrome receive regular (3-4 yearly) kidney surveillance for Wilms' tumour until at least the age of 6-8 years and thereafter remain under some follow-up because of the risk of late onset nephropathy (40% of patients over the age of 12 years). (wikipedia.org)
  • Mesoblastic
  • In addition to Wilms tumor and hepatoblastoma, children with BWS have been shown in individual case reports to develop ganglioneuroma, adrenocortical carcinoma, acute lymphoid leukemia, liver sarcoma, thyroid carcinoma, melanoma, rhabdomyosarcoma, and mesoblastic nephroma. (wikipedia.org)
  • Wilms tumor, hepatoblastoma, and mesoblastic nephroma can usually be cured if diagnosed early. (wikipedia.org)
  • Surgery
  • Staging is based on the results of the physical exam and imaging tests (ultrasound, CT scans, etc.), which are described in Tests for Wilms Tumors , as well as on the results of surgery to remove the tumor, if it has been done. (cancer.org)
  • The tumor is contained within one kidney and was removed completely by surgery . (cancer.org)
  • The tumor was not biopsied before surgery to remove it. (cancer.org)
  • The tumor has grown beyond the kidney, either into nearby fatty tissue or into blood vessels in or near the kidney, but it was removed completely by surgery without any apparent cancer left behind. (cancer.org)
  • The tumor was not biopsied before surgery. (cancer.org)
  • A biopsy of the tumor was done before it was removed with surgery. (cancer.org)
  • In the United States, surgery is the first treatment for most Wilms tumors. (cancer.org)
  • For these children, doctors might use chemotherapy, radiation therapy, or a combination of the 2 to try to shrink the tumor(s) before surgery. (cancer.org)
  • Most children with Wilms tumour will have surgery. (cancer.ca)
  • The type of surgery used depends mainly on whether or not the tumour is resectable, which means that it can be removed with surgery. (cancer.ca)
  • The following are the types of surgery most commonly used to treat Wilms tumour. (cancer.ca)
  • Before surgery, doctors will use diagnostic tests to find out the extent of the tumour. (cancer.ca)
  • Even when a tumour is thought to be unresectable, the surgeon will examine it during surgery to determine if it can actually be removed. (cancer.ca)
  • But during surgery, the surgeon may find that the tumour can't be completely removed with surgery, or it is unresectable. (cancer.ca)
  • Antuan Brown says 'The next day they did surgery, took out his right kidney, along with tumor attached to it. (wrcbtv.com)
  • However, CT scanning does not aid in determining whether the tumor can be removed, because this is accurately assessed only at the time of surgery. (medscape.com)
  • Tumor spillage involving peritoneal surfaces either before or during surgery, or transected tumor thrombus. (wikipedia.org)
  • The tumor has been biopsied prior to removal or there is local spillage of tumor during surgery, confined to the flank. (wikipedia.org)
  • surgeon
  • Wilms tumors usually need to be removed by a surgeon, either before or after additional therapy. (stbaldricks.org)
  • It is named after Dr. Max Wilms, the German surgeon (1867-1918) who first described it. (wikipedia.org)
  • In such cases, surgical intervention by a surgeon who is experienced in the removal of such a fragile tumor is imperative. (wikipedia.org)
  • lymph node
  • Stage IV Wilms tumor is defined as the presence of hematogenous metastases (lung, liver, bone, or brain), or lymph node metastases outside the abdomenopelvic region. (wikipedia.org)
  • Perlman
  • Diagnosis of Perlman syndrome also overlaps with other disorders associated with Wilms tumor, namely, Sotos syndrome and Weaver syndrome. (wikipedia.org)
  • radiation
  • Depending on the spread of the tumour, radiation therapy may be given to just the kidney area or to the entire abdomen. (cancer.ca)
  • Radiation therapy may be given to the chest to treat Wilms tumour that has spread, or metastasized, to the lung. (cancer.ca)
  • In 3D-CRT, the radiation oncologist uses MRI images to map the exact location and shape of the tumour. (cancer.ca)
  • Several radiation beams are then shaped and aimed at the tumour from different directions to treat the tumour from all angles. (cancer.ca)
  • A higher dose of radiation is delivered where the beams converge at the tumour. (cancer.ca)
  • This allows a higher dose to be delivered to the tumour and reduces the dose of radiation reaching nearby normal tissues. (cancer.ca)
