Open partial nephrectomy for renal cell cancer in a medium patient volume centre: is high quality possible?

OBJECTIVE: To describe the surgical complication rate of open partial nephrectomy (OPN) in patients with renal tumours, and to report the oncological long-term outcome in unilateral renal cell cancer patients subjected to this procedure, from a medium patient volume urological centre. MATERIAL AND METHODS: Data from all patients (n = 89) subjected to OPN for proven or suspected renal cell cancer during the period 1965-2007 were registered in a specifically designed database system. Tumour stage and size, surgical margin, histology, perioperative and postoperative complications were analysed in all patients. In addition, long-term follow-up outcomes in malignant unilateral tumours (n = 51) were analysed. RESULTS: Seventy-four of the resected tumours were malignant. Six of these had a positive surgical margin; five from patients with multifocal or bilateral tumours and one from a patient with a solitary malignant cyst. Perioperative complications were registered in only one case (1%). Postoperative complications (within 30 days postoperatively) reached 18%. The long-term follow-up (mean 79 months, median 49 months, range 14 months to 26 years) in patients with unilateral malignant tumours, all staged T1-T2, revealed two systemic recurrences, both in patients with poor prognostic markers at the time of surgery, but no local recurrence. CONCLUSIONS: OPN has complication rates similar to open radical nephrectomy. Long-term tumour control in unilateral cases and with organ confined disease is excellent. The results demonstrate that carefully performed OPN at a medium-volume centre can achieve equal results to high-volume centres.
