Abstract：
OBJECTIVES:To evaluate the incidence and sites of retroperitoneal recurrence after modified retroperitoneal lymph node dissection (RPLND) for low-stage nonseminomatous germ cell tumors (NSGCTs). METHODS:A retrospective review of 88 patients who underwent RPLND for Stage I or II NSGCTs between 1971 and 1991 was performed to determine the incidence and site of any retroperitoneal recurrence. RESULTS:Six retroperitoneal recurrences (four isolated and two in conjunction with failures at other sites) were found with a minimum follow-up of 5 years. All 6 patients had left-sided primary tumors, with three recurrences near the left renal hilum and two near the right renal hilum. All recurrences were at or outside the boundaries of the surgical dissection. Only one retroperitoneal recurrence may have been prevented by performing a bilateral dissection. CONCLUSIONS:Although uncommon, local recurrences can occur after RPLND. The right and especially the left renal hilum appear to be at higher risk of failure, possibly because of incomplete dissection in these areas. A more complete dissection in these areas may further decrease the local recurrence rate. Overall, the data presented and the studies reviewed suggest that modified RPLND reliably removes metastatic tumor with a low failure rate. If failures do occur, they are usually outside of the template and would not necessarily be prevented with a complete bilateral infrahilar dissection.
