Wilms Tumor Ppt New ((full)) Review

Never palpate aggressively – risk of tumor rupture and upstaging.

Characterized by Wilms tumor, Aniridia, Genitourinary anomalies, and Range of developmental delays (deletion at 11p13 involving WT1 and PAX6 ).

: Standard procedure involving complete removal of the affected kidney and ureter. wilms tumor ppt new

The fundamental difference lies in the timing of the nephrectomy: COG protocols mandate immediate upfront surgery, whereas SIOP protocols utilize preoperative chemotherapy before surgical resection. Summary of Clinicopathologic Staging (Post-Nephrectomy) Description

: A highly effective mnemonic for presentations, noting that roughly 10% of cases are bilateral, 10% have unfavorable histology, 10% show vascular invasion, and 10% present with pulmonary metastases. Never palpate aggressively – risk of tumor rupture

: Characterized by early-onset renal failure, XY gonadal dysgenesis, and a high risk of Wilms tumor due to specific WT1 missense mutations. Pathophysiology and Histopathology

Evaluates local tumor extent, relationships to major vessels, presence of retroperitoneal lymphadenopathy, and synchronous contralateral lesions. MRI is preferred by many centers to minimize radiation exposure. The fundamental difference lies in the timing of

One key slide: Algorithm for first relapse (early vs late, anaplastic vs favorable).

Mutated in roughly 10–20% of sporadic cases; crucial for normal renal development. CTNNB1: Mutations in the

: Characterized by marked nuclear enlargement, hyperchromasia, and multipolar mitotic figures. Anaplasia correlates strongly with chemotherapy resistance. Clinical Presentation
