Intratubular Germ Cell Neoplasia of the Contralateral Testis in Testicular Cancer : Defining a High Risk Group
J Urol 160 : 1353-1357, 1998
Conclusions – Among patients with testicular cancer, the risk of carcinoma in situ of the contralateral testis is elevated for those with atrophy of the contralateral testis and those aged 30 years or younger. This group, comprising about 6% of all patients with testicular cancer, is therefore at increased risk of a second germ cell tumor. Referral of these patients for biopsy of the contralateral testicle will provide positive results in about one third of the cases, while identifying about 40% of all cases of contralateral carcinoma in situ.
