[Surgery for renal carcinoma metastases]

Area of Science:

• Urology
• Oncology
• Surgical Oncology

Context:

• Increasingly sophisticated diagnostic imaging, particularly ultrasound, aids early detection of asymptomatic renal neoplasms.
• Renal cell carcinoma (RCC) remains a high-mortality cancer, often due to distant metastases.
• Systemic treatment for metastatic RCC lacks consensus, positioning surgery as a primary option for metastasis removal.

Purpose:

• To evaluate the efficacy of metastasectomy versus other therapeutic modalities in patients with metastatic renal cell carcinoma.
• To identify prognostic factors and optimal treatment strategies for RCC with distant spread.

Summary:

• A retrospective study analyzed 1475 patients with renal cell carcinoma (RCC) treated surgically since 1983.
• Of 304 patients developing metastases, 230 had single-site disease. Metastasectomy in single-site cases resulted in 16.9% disease-free survival (33/111 patients).
• Surgery for single-site metastases (lung or adrenal) demonstrated superior survival outcomes compared to medical therapy, radiotherapy, or palliative care.

Impact:

• Surgical metastasectomy is the most effective approach for achieving long-term survival in a subset of patients with single-site metastatic RCC.
• Emerging biologic drugs targeting tumor proliferation and angiogenesis may offer future multimodal treatment options for metastatic RCC.
• This study supports surgical intervention as a critical component of managing localized metastatic renal cell carcinoma.
