Overview
There are 5 stages of wilms' tumor based on both the results of the imaging studies and the surgical and pathologic findings at nephrectomy.
Staging
- Staging of wilms tumor is done based upon:
- Extent of tumor anatomically.
- It is not done on the basis of its genetics, histology or molecular markers.
- Extensive disease and worse prognosis is denoted by a higher stage.
- Patients suffering from a higher stage tumor get more aggressive treatment modalities.
- The staging systems that are currently used are:[1]
- National Wilms Tumor Study (NWTS) system.
- International Society of Pediatric Oncology (SIOP) system.
