Report of the long-term efficacy of two cycles of adjuvant bleomycin/etoposide/cisplatin in patients with stage I testicular nonseminomatous germ-cell tumors (NSGCT): a risk adapted protocol of the Hellenic Cooperative Oncology Group.

OBJECTIVES: Stage I testicular nonseminomatous germ-cell tumors (NSGCT) are highly curable. Following orchidectomy surveillance, adjuvant chemotherapy and retroperitoneal lymph node dissection can be applied. Certain factors are used to select patients in high-risk for relapse. We report the outcome and safety of a risk-adapted strategy by the Hellenic Cooperative Oncology Group.

METHODS: Between 1994 and 2004, 142 patients with stage I NSGCT and 1 of the following risk factors: lymphovascular invasion (LVI), invasion of tunica vaginalis, spermatic cord, rete testis or scrotal wall, embryonal component >50% of the total tumor, were prospectively included in a protocol of adjuvant chemotherapy consisting of two 3-week courses of bleomycin 15 IU, etoposide 120 mg/m(2), and cisplatin 40 mg/m(2) for 3 consecutive days with G-CSF support.

RESULTS: Median follow-up was 79 months and 138 patients have been followed for at least 2 years. Seventy-seven patients (54%) had LVI and 74 (52%) had >50% embryonal component. There was 1 relapse, which was cured with chemotherapy and surgery. Another patient died due to disease-unrelated causes and 1 patient developed a new primary of the remaining testicle, which was cured with surgery.

CONCLUSION: Two cycles of bleomycin/etoposide/cisplatin is an effective and safe form of adjuvant therapy in high-risk stage I NSGCT.
