Abstract:OBJECTIVE: To critically analyse the results of laparoscopic cytoreductive surgery for renal cell carcinoma (RCC), as phase III evidence supports cytoreductive nephrectomy before immunotherapy, and there is an overall shift towards minimally invasive renal surgery for this disease. PATIENTS AND METHODS: Since October 2000, 22 patients were treated by laparoscopic cytoreductive nephrectomy for metastatic RCC (group 1). All patients had radiological evidence of metastatic disease, with biopsy confirmation in 10. To put the results into perspective, 25 consecutive contemporary patients with large organ-confined nonmetastatic RCC (>7 cm, clinical stage T2) undergoing laparoscopic radical nephrectomy (group 2) were compared retrospectively. The baseline demographics were comparable between the groups. RESULTS: The mean tumour size was 8 cm in group 1 and 9.6 cm in group 2 (P = 0.07). Variables during and after surgery were comparable between the groups, with a mean operative duration of 3.1 vs 3.2 h (P = 0.82), blood loss of 285 vs 308 mL (P = 0.79), complications in two vs eight (P = 0.08), morphine sulphate equivalent requirements of 51.7 vs 44.1 mg (P = 0.1) and a median length of hospital stay of 1.7 vs 1.6 days (P = 0.68). In group 1 the median (range) time to immunotherapy was 35 (13-136) days. CONCLUSIONS: Laparoscopic cytoreductive nephrectomy is safe and effective in selected patients. Currently the procedure is offered to candidates eligible for immunotherapy and with tumours of < or = 15 cm, and no evidence of adjacent organ invasion or inferior vena caval thrombus. Significant perihilar adenopathy and numerous parasitic vessels can increase the complexity of the surgery. Adequate laparoscopic experience is necessary.
