Wilms Tumor Ppt New -

Wilms tumor , also known as nephroblastoma , is a rare but highly significant kidney cancer that primarily affects children. Often discovered as an asymptomatic abdominal mass during routine activities like bathing, it represents one of the most successful stories in modern oncology, with survival rates having risen from 30% in the 1930s to approximately Epidemiology and Clinical Presentation

Wilms tumor is the most common pediatric renal malignancy, typically diagnosed in children between the ages of

. While most cases are sporadic, about 10% are associated with specific genetic syndromes like Denys-Drash Beckwith-Wiedemann

The clinical presentation often follows a predictable pattern: Wilms Tumor - StatPearls - NCBI Bookshelf - NIH wilms tumor ppt new

Outcomes and Prognosis

• Overall survival: >85% in high-resource settings, varying by stage and histology.
• Favorable histology and early-stage disease have best outcomes.
• Poor prognostic factors: anaplasia (especially diffuse), metastases at diagnosis, LOH 1p/16q, older age in some series.

Slide 6: Diagnostic Workup

• Imaging:
  • Abdominal ultrasound (first-line) – solid intrarenal mass.
  • Contrast-enhanced CT chest/abdomen – primary tumor evaluation + lung metastases (most common site).
• Laboratory: Urinalysis, CBC, renal function, LDH.
• Tissue Diagnosis: Core needle biopsy if neoadjuvant chemotherapy planned (or surgical resection upfront depending on protocol).

Slide 4: Clinical Presentation

• Classic triad (less common now due to early detection):
  • Asymptomatic abdominal mass (parents may notice while bathing child).
  • Hematuria (microscopic or gross; 15–20%).
  • Hypertension (due to renin secretion; 25%).
• Other symptoms:
  • Abdominal pain, fever, malaise, weight loss.
  • Varicocele (left-sided due to IVC invasion).
• Important: Do not palpate aggressively → risk of tumor rupture & upstaging.

Wilms Tumor (Nephroblastoma): Current Insights, Modern Management, and Recent Advances

Conclusion

Wilms tumor is a pediatric renal malignancy with generally favorable outcomes when treated in multidisciplinary protocols. Management balances tumor control with preservation of renal function and minimization of long-term treatment toxicity. Ongoing research focuses on refining risk-adapted therapy through molecular markers and novel treatments.

This report outlines the essential components for a comprehensive presentation on Wilms Tumor (Nephroblastoma), incorporating the latest 2025–2026 clinical guidelines and research updates. 1. Epidemiology and Clinical Presentation

Epidemiology: Wilms tumor is the most common primary pediatric kidney malignancy, accounting for over 90% of all childhood renal tumors . Peak Age: Typically diagnosed between 3 and 5 years old . Outcomes and Prognosis

Demographics: Slightly higher incidence in females and Black populations; lowest in Asian populations . Key Clinical Signs:

Asymptomatic Abdominal Mass: Found in ~80% of cases, often discovered incidentally during bathing or dressing .

Hypertension: Present in ~25% of patients due to increased renin activity .

Hematuria: Gross or microscopic hematuria occurs in 20–30% of cases . 2. Staging and Histopathology

The prognosis and treatment intensity are strictly determined by these two factors: Wilms Tumor - StatPearls - NCBI Bookshelf - NIH
