Post-chemotherapy nerve-sparing retroperitoneal lymph node dissection for advanced germ cell tumor.
International Journal of Urology : Official Journal of the Japanese Urological Association 2009 April
OBJECTIVE: To report our experience with post-chemotherapy nerve-sparing retroperitoneal lymph node dissection (RPLND) for advanced germ cell tumor (GCT).
METHODS: Between 1994 and 2008, 92 patients with advanced GCT underwent RPLND after multiple treatments with systemic chemotherapy at our institution. A nerve-sparing RPLND was carried out in 78 patients (84.8%; median age 32 years). Of them, 19 had a seminoma and 59 had a non-seminoma.
RESULTS: Lumbar splanchnic nerves controlling ejaculatory function were macroscopically preserved during RPLND. Bilateral and unilateral lumbar splanchnic nerves were preserved in 40 patients and 38 patients, respectively. Sixty-five patients could be evaluated for ejaculation. Fifty-four patients (83.1%) achieved antegrade ejaculation with a median postoperative interval of 3 months (range: 1-10 months). Twenty-eight patients (28/30: 93.3%) and 26 patients (26/35: 74.3%) undergoing bilateral and unilateral nerve-sparing RPLND had antegrade ejaculation, respectively (P = 0.041). Only two patients (2.6%) had mediastinal and retroperitoneal recurrences during a median follow-up of 42 months (range: 1-138 months), respectively. However, these patients were cured by chemotherapy and surgery.
CONCLUSIONS: Post-chemotherapy nerve-sparing RPLND preserves ejaculatory function in the majority of patients with advanced GCT without increasing the risk of local recurrence.
