Background

Partial nephrectomy has been considered an effective and efficient method in the treatment of localized renal cell carcinoma. Herein, we retrospectively review our experience with partial nephrectomy in the treatment of localized renal cell carcinoma and compared it with patients who received radical nephrectomy.

Methods

From 1982 to 2005, 35 patients who received partial nephrectomy for localized renal cell carcinoma were enrolled in this study. Ten patients were female (28.6%). The median age was 70 years (range, 42–82 years). Sixteen (45.7%) patients had pathologic T1a tumors; 17 (48.6%) patients had pathologic T1b tumors and 2 (5.7%) patients had pathologic T2 tumor (7 cm). In the meantime, 128 patients who had T1N0M0 renal cell carcinoma and who received radical nephrectomy were assigned to a control group. Thirty-nine patients (30.5%) were female in this group. The median age was 62 years (range, 30–83 years). The tumor characteristics, location, surgical techniques and patient survival were subsequently compared.

Results

The median tumor size in the partial nephrectomy group was 3.9 cm (range, 1.5–7.0 cm), and it was 4.5 cm (range, 1–6.5 cm) in radical nephrectomy group. The tumor size was smaller in the partial nephrectomy group (p = 0.003). The median follow-up period was 4.38 years (range, 0.05–17.99 years) in the partial nephrectomy group and 5.66 years (range, 0.01–22.25 years) in the radical nephrectomy group. There was no local recurrence or distant metastasis in the partial nephrectomy group. The 5-year overall survival was 85.0% compared with 91.4% in the radical nephrectomy group (p = 0.126). The 5-year disease-specific survival in the partial nephrectomy group was 100%. The postoperative serum creatinine level increased to > 2.0 mg/dL in 5 (14.3%) patients in the partial nephrectomy group, but no patient needed hemodialysis during follow-up.

Conclusion

From our review, partial nephrectomy is safe and provides excellent disease control in the treatment of localized renal cell carcinoma in selected patients. Renal function preservation was observed in the partial nephrectomy group, while the operated kidney showed functioning in the follow-up nuclear medicine survey.
