    Abstract:
    OBJECTIVES: To evaluate the feasibility, morbidity, and long-term oncologic efficacy of laparoscopic retroperitoneal lymph node dissection (L-RPLND) in patients with nonseminomatous germ cell tumor (NSGCT). METHODS: L-RPLND was performed 188 times in 185 patients; 114 procedures were performed for Stage I NSGCT and 6 procedures for tumor marker-negative clinical Stage IIA disease. In the case of positive lymph nodes, adjuvant cisplatin-based chemotherapy was administered. After chemotherapy, L-RPLND was performed for retroperitoneal Stage IIA (10 patients), IIB (43 patients), and IIC lesions (15 patients). RESULTS: The mean operative time was 256 minutes for Stage I and 243 minutes for Stage II; the conversion rate was 2.6%. The mean blood loss was 159 mL in patients with Stage I and 78 mL in those with Stage II disease. Active tumor was found in 19.5% of patients with Stage I lesions and in 50% of patients with tumor marker-negative clinical Stage IIA disease. After chemotherapy, active tumor was found in 1 patient with Stage IIC disease and mature teratoma in 38.2% of patients. The mean postoperative hospital stay for those with Stage I and II disease was 4.1 and 3.7 days, respectively. Antegrade ejaculation was preserved in 98.4% of patients. The mean follow-up was 53.7 months for those with Stage I and 57.6 months for those with Stage II disease. All but 6 patients have remained free of relapse, and no patient died of tumor progression. CONCLUSIONS: The rate of tumor control after L-RPLND and the diagnostic accuracy of L-RPLND were equal to the open procedure, and the morbidity was significantly lower. Therefore, L-RPLND for Stage I and low-volume retroperitoneal Stage II disease can be performed at centers with experience in urologic laparoscopy and oncology.
