Learn about testicular cancer, one of the most common solid tumors affecting young adult men, through this comprehensive 21-minute podcast episode. Begin with a classic clinical vignette of a young male presenting with a painless testicular mass, then explore the epidemiology and key risk factors for testicular germ cell tumors, including cryptorchidism, family history, and Klinefelter syndrome. Distinguish between the two major types of testicular cancer—seminomas and nonseminomas—while examining their unique biological behaviors and typical age distributions. Dive deep into the pathophysiology of germ cell tumors and discover how tumor markers like AFP, β-hCG, and LDH guide diagnosis and treatment decisions. Compare the classic presentations of seminomas, which are often β-hCG positive and radiosensitive, versus nonseminomas, which are associated with aggressive behavior and elevated AFP/β-hCG levels. Master the diagnostic workbook including scrotal ultrasound, serum tumor marker analysis, and CT imaging for staging, while understanding the critical importance of inguinal orchiectomy as both a diagnostic and therapeutic intervention. Explore comprehensive treatment strategies based on stage and histology, ranging from surveillance and radiation therapy for early-stage seminomas to cisplatin-based chemotherapy regimens and retroperitoneal lymph node dissection for advanced or nonseminomatous disease.
