This meta-analysis examined 259 cases of epithelioid angiomyolipoma (eAML), a rare malignant renal tumor. The study found a 39% recurrence rate at a median follow-up of 21 months, with significant risk factors including positive hilar lymph nodes and vascular invasion. The analysis highlights the need for effective management strategies due to eAML's aggressive nature.
Key findings
- 39% of patients experienced recurrence at a median of 12 months post-treatment.
- Five-year overall survival was 84%, with cancer-specific survival at 85%.
- Positive hilar lymph nodes were associated with a 15.6-fold increased risk of recurrence.
- Radical nephrectomy was performed in 71% of cases.
Why it matters
Understanding the clinical characteristics and outcomes of eAML is crucial for developing effective management strategies. The high recurrence rate and associated risk factors can inform follow-up protocols and treatment decisions for affected patients.
What to keep in mind
The study acknowledges publication bias and heterogeneous reporting among included cases.
