| Locus | Mutation Frequency | |-------|-------------------| | 11p15 epigenetic abnormalities (H19 epimutation or pUPD) | 69% | | WTX | 32% | | CTNNB1 | 15% | | WT1 | 12% | | TP53 | 5% |
Other risk factors include age <5 years, congenital urogenital anomalies, family history of Wilms tumor, and antenatal exposure to harmful environmental factors.
Evaluates local tumor invasion, status of the contralateral kidney, and lymph node involvement.
The field of Wilms tumor research is rapidly evolving, with several exciting developments in the past year.
Distant hematogenous metastases present (lungs, liver, bone, or brain).
A modern presentation must highlight the genetic landscape, as treatment is increasingly driven by molecular profiling. Approximately 10% to 15% of children with Wilms tumor present with an underlying congenital anomaly or genetic syndrome. WT1-Related Syndromes (Chromosome 11p13)
Tumor extends beyond the kidney but is completely excised; regional lymph nodes are negative.
