CASTILLO, O.A. et al. Primary laparoscopic retroperitoneal lymph node dissection for clinical stage I nonseminomatous germ-cell testis tumor. Actas Urol Esp [online]. 2011, vol.35, n.1, pp.22-28. ISSN 0210-4806.

Introduction: This report is intended to retrospectively assess cancer control and morbidity of primary laparoscopic reproperitoneal lymphadenectomy (L-RPLND) in patients with clinical Stage I non seminomatous germ cell tumour (NSGCT). Materials and methods: One hundred and sixty-four patients with clinical Stage I NSGCT underwent primary diagnostic LRPLND between 1993 and 2006. Patients were operated unilaterally limiting the dissection to templates. Kaplan Meier curves were generated estimating time to recurrence. Results: Of the 164 patients, 82 (48%) had embryonal components and 35 (20%) lymphovascular invasion in the orchiectomy specimen. The median (IQR) age, operative time, length of hospital stay, blood loss and number of lymph nodes retrieved was 28 years (24-33), 135 minutes. (120- 180), 48 hours (24-48), 50 cc (20-100) and 14 (10-18) nodes, respectively. All patients had negative serum markers preoperatively. Presence of lymph node metastasis was identified in 32 (19.5%) patients. Follow-up was available in 15 of these. Fourteen received adjuvant chemotherapy and 2 of them had recurrence at 3 and 64 months. Absence of lymph node metastasis was diagnosed in 132 (80.5%) patients. Follow-up was available in 80 of these. Among them 7 recurred (5 retroperitoneum, 2 lung), one of them 33 months after L-RPLND. Median follow-up for patients without recurrence was 14 months (IQR:4-35). The cumulative 3-year recurrence free rate was 82% (95%CI: 64-91). Seventeen (10%) of 164 patients had intra or perioperative complications. Conclusions: This is the largest series of L-RPLND performed in a single institution. Both morbidity and oncologic safety of this technique needs to be prospectively evaluated in randomized trials.
