Nicolai N, et al. - This trial strived to discern the tolerability, safety and efficacy of Laparoscopic retroperitoneal lymph-node dissection (L-RPLND) in stage I non-seminomatous germ-cell tumors of the testis (NSGCTT) in a high-volume center. The inference drawn was that L-RPLND was safe, displaying an oncologic efficacy comparable with open surgery, in the backdrop of a high-volume center. L-RPLND could be recommended as an alternative to other options for the enrolled stage I NSGCT patients.
