Update on testicular germ cell tumors.

PURPOSE OF REVIEW This overview discusses several important developments in testicular germ cell tumors (TGCTs) over the past year. RECENT FINDINGS Genomic studies continue to investigate gene expression as possible markers for disease relapse and metastatic potential. Optimal treatment strategies for early-stage seminomas continue to evolve toward surveillance versus chemotherapy, although developing radiation delivery modalities may ultimately provide a safe alternative. The role of retroperitoneal lymph node dissection in postorchiectomy early-stage nonseminoma germ cell tumors remains a topic of debate. SUMMARY Treatment paradigms continue to be refined for TGCTs as research in these areas continues.
