Summary
Lymph node dissection (LND) during nephrectomy is crucial for accurate renal cell carcinoma staging. Patients without LND had worse survival rates, highlighting the importance of nodal status in predicting outcomes.
Area of Science:
- Urology
- Oncology
- Surgical Pathology
Background:
- Nephrectomy is the standard treatment for renal cell carcinoma.
- Accurate staging is vital for treatment planning and prognosis.
- Lymph node dissection (LND) is often omitted, leading to incomplete staging.
Purpose of the Study:
- To investigate the impact of lymph node dissection (LND) during nephrectomy on patient survival in renal cell carcinoma.
- To evaluate the prognostic significance of nodal status (N stage) in renal cell carcinoma patients.
Main Methods:
- Retrospective analysis of 181 renal cell carcinoma patients undergoing nephrectomy.
- Patients were categorized into four groups based on TNM staging (N0, NX, N1, M1).
- Overall survival and disease-free survival were calculated and compared across groups.
Main Results:
- Median survival varied significantly across groups: not reached (N0), 89 months (NX), 50 months (N1), and 39 months (M1).
- Patients with NX (unknown nodal status due to no LND) had worse survival than N0 (P=0.002).
- N1 (node-positive) and M1 (metastatic) patients exhibited poor survival rates.
Conclusions:
- Incomplete staging due to lack of LND impacts survival assessment in renal cell carcinoma.
- NX patients demonstrate inferior survival compared to N0 patients.
- Nodal positivity and metastasis are critical indicators of poor prognosis, warranting classification as advanced disease.
