First-line treatments
Pharmacological management with first-line agents
Active treatment with regular monitoring by a healthcare provider is recommended.
Radical Surgery
Surgical removal of the primary tumor and affected tissues, which may include orchiectomy for testicular tumors or resection of extragonadal masses. Aim is complete tumor excision with negative margins.
Platinum-Based Chemotherapy
Systemic chemotherapy using cisplatin or carboplatin combined with other agents to treat metastatic or high-risk germ cell tumors. Highly effective with potential for cure even in advanced disease.
Additional treatment options
Fertility Preservation
Sperm banking or other reproductive preservation methods offered before cancer treatment that may affect fertility. Should be discussed early in treatment planning.
procedureTumor Marker Surveillance
Regular blood testing for tumor markers such as AFP, hCG, and LDH to monitor treatment response and detect early recurrence. Essential component of follow-up care.
monitoringRadiation Therapy
Targeted radiation treatment for specific germ cell tumor subtypes, particularly seminomas, where radiation provides effective local disease control.
procedureWhen to seek medical help
