Abstract: | OBJECTIVES: To examine the operative findings, histopathology and clinical outcome of patients undergoing repeat retroperitoneal lymph node dissection (RPLND) after initial chemotherapy and RPLND (PC-RPLND) for metastatic testicular germ cell tumour (GCT), as a small proportion relapse or have residual disease after incomplete resection in the lung, retrocrural or pelvic nodes, and retroperitoneum. PATIENTS AND METHODS: Between September 1992 and May 2006, 359 patients had PC-RPLND under the care of one surgeon, 54 of which were repeat procedures. We compared the long-term outcome between those having primary and those having repeat PC-RPLND. RESULTS: The median (range) time from original to repeat surgery was 2.4 (0.25-26.5) years, and the median follow-up after the repeat procedure was 5.8 (0.08-12.9) years. There was no difference in survival between patients requiring only one PC-RPLND and those having a repeat procedure (P = 0.592). The most frequent sites of recurrent disease were: behind the great vessels/para-aortic areas (38, 46%), in the suprahilar region (18, 18%), in the retrocrural area (16, 19%), in the pelvic nodes (10, 12%) and in the lung (one, 1%). The most common pathological findings in the repeat PC-RPLNDs were differentiated teratoma (19, 35%), malignant teratoma undifferentiated (nine, 17%), adenocarcinoma (eight, 15%) and necrotic tissue (five, 9.2%). CONCLUSION: Although a small proportion of patients with metastatic GCT might require repeat PC-RPLND, there is no difference in survival between this group and those having one PC-RPLND. However, to avoid cancer recurrence and reoperation, it is crucial that the first PC-RPLND is careful and complete, preferably done in a centre with expertise in this procedure. |
