Dr Anil K. D’ Cruz, Director and chief Head and Neck Services, Tata Memorial Hospital, Mumbai has prepared Standard Treatment Guidelines for Wilms tumour on behalf of Ministry of Health and Family Welfare, Government of India which has released the same.

Wilms  tumour is the most common renal malignancy in children. It predominantly affects children under 5 years of age, most commonly during the first 2 years of life. Contemporary treatment of Wilms tumour has led to an overall survival of over 85% and the emphasis is now shifting from successful treatment to reducing treatment-associated morbidity without loss of efficacy.

Following are the major recommendations :

Radiological report for Wilms Tumour

Should be a contrast enhanced CT/MRI of abdomen
Laterality: Right or Left or Bilateral disease
Location: which pole

Local extent:

  • Is it Completely Intra-renal location or is Perinephric spread evident
  • Renal sinus infiltration.
  • Renal vein status
  • IVC status.
  • Renal artery : comment about the abdominal origin as well, comment on accessory arteries if any
  • Infiltration of liver, pancreas, bowel, GB, or abdominal wall

Significant ascites, Peritoneal implants
Adenopathy: Enlarged nodes
Metastatic disease: Lung, liver, bone or extra-abdominal nodes
