Short-course adjuvant chemotherapy in high-risk stage I nonseminomatous germ cell tumors of the testis: a Medical Research Council report.

There have been only two relapses among 114 cases of high-risk stage I NSGCTT treated with two courses of adjuvant BEP chemotherapy. The 95% confidence interval (CI) excludes a true relapse rate of more than 5%. Of 104 patients confirmed on histopathology review to have GCT, there has been only one relapse. Adjuvant chemotherapy is free from significant long-term toxicity, offering an effective alternative to surveillance or retroperitoneal lymph node dissection (RPLND) followed by surveillance, and may be preferred by some patients.
