Testicular Germ Cell Tumors: A Review

Area of Science:

• Oncology
• Urology

Background:

• Testicular cancer is the most common solid malignancy in US males aged 15-40.
• Germ cell tumors (GCTs) constitute 90-95% of testicular cancers.
• Key risk factors include cryptorchidism, family history, and Klinefelter syndrome.

Purpose of the Study:

• To outline the diagnosis and management of testicular cancer.
• To emphasize the importance of early detection and treatment.
• To highlight the need to balance oncologic outcomes with long-term survivorship.

Main Methods:

• Clinical presentation and diagnostic workup including physical exam, scrotal ultrasound, and tumor markers (AFP, hCG, LDH).
• Staging based on tumor location and metastasis (Stages I-III).
• Treatment modalities including radical inguinal orchiectomy, surveillance, retroperitoneal lymph node dissection, chemotherapy, and radiation.

Main Results:

• 5-year survival rates are 99% for Stage I, 92% for Stage II, and 85% for Stage III GCTs.
• Early diagnosis and treatment significantly improve patient outcomes.
• Multidisciplinary care at experienced centers is crucial for optimal management.

Conclusions:

• Testicular cancer, particularly GCTs, has high survival rates with prompt diagnosis and appropriate treatment.
• Treatment decisions must integrate oncologic control with comprehensive survivorship care.
• Addressing long-term effects like fertility, hypogonadism, and psychosocial well-being is essential for quality of life.
