Single center preliminary experience with hand-assisted laparoscopic resection of isolated renal cell carcinoma fossa recurrences.

Objectives: Solitary metastasis to the renal fossa after radical nephrectomy for renal cell carcinoma is uncommon. We report the first series on hand-assisted laparoscopic excision for renal cell carcinoma fossa recurrences.

Methods: We performed a retrospective review of patients who underwent hand-assisted laparoscopic excision of renal cell carcinoma fossa recurrence. Patients with distant metastasis or local lymph node or adrenal metastasis were excluded from analysis. We collected data on patient and tumor characteristics, nephrectomy and fossa mass excision procedures, and postoperative outcomes.

Results: Between 2001 and 2007, 5 patients underwent laparoscopic resection of a renal fossa recurrence. Mean time to recurrence after radical nephrectomy was 23 months (range, 5 to 46 months) and mean size of the renal fossa mass was 6 cm (range, 4.2 to 9.5 cm). The average operative time was 232 minutes (range, 150 to 300 minutes) and average estimated blood loss was 175 mL (range, 25 to 400 mL). One patient required conversion to open surgery. There were no postoperative complications and mean hospital stay was 4 days. With mean follow-up of 43 months, the cancer-specific and disease-free survival rates were 60% and 20%, respectively. Of the 4 patients who underwent complete resection, 2 died from metastatic disease at 13 and 56 months, 1 continues to have progressive metastatic disease at 69 months, and 1 remains free of any clinical evidence of metastatic disease or recurrence at 37 months. One patient who underwent incomplete resection as a result of inferior vena cava invasion continues to have progressive local and distant metastatic disease at 40-month follow-up.

Conclusions: Hand-assisted laparoscopic excision of renal fossa recurrence after radical nephrectomy appears to be safe and effective for carefully selected patients.
