PURPOSE: Local excision of germ cell tumor in the remaining testicle followed by a modest dose of irradiation is an alternative to orchiectomy. This organ sparing technique provides superior quality of life and reduces the need for lifelong hormone replacement. MATERIALS AND METHODS: We treated two patients with contralateral seminomas with organ preservation. Both patients received postoperative irradiation to the remaining testicle to a dose of 20 Gy in 10 fractions and 19.8 Gy in 11 fractions. RESULTS: Both patients are alive with no evidence of disease more than 3 years since the completion of their treatments. They both have reduced but preserved androgen production and retained their virility. They both are azospermic. CONCLUSION: We conclude that organ preservation for the treatment of contralateral testicular seminoma is a superior alternative to orchiectomy of the remaining testicle. It preserves male hormone production with equal survival outcome expectations.
