Salvage HDC in female pts w/ relapsed/refractory GCT: a retrospective analysis of EBMT

What about Routine Contralateral Testicular Biopsy?

• 3.5-5% of pts w/ testicular GCT develop a contralateral GCT• TIN (testicular intraepithelial neoplasia, or CIS) can be

detected in ~5% of contralateral testicular biopsies• TIN progress to GCT in 50-70% of pts within 5-7 years• Testicular low dose RT (16Gy) can prevent progression from

TIN to GCT but compromises testicular funtion

Thus, Routine Contralateral Testicular Biopsy is controversial
