INTRODUCTION: Testicular germ cell tumors are the most common malignancy among men aged 40 and less. Since the introduction of cisplatin-based combination chemotherapy, germ cell tumors are among the most curable solid tumors with cure rates of 95% in all patients and > 80% in metastatic disease. Areas covered: Current standards and future developments in GCT treatment, including adjuvant chemotherapy, first line treatment for metastatic disease, and salvage regimens in case of relapse and refractory disease. Expert opinion: Maintaining therapeutic success while further reducing treatment-related toxicity is paramount. Cancer-specific survival in localized disease approximates 100%. Therefore, orchidectomy followed by active surveillance is the preferred approach for all seminomas and non-seminomas lacking lymphovascular invasion. Non-seminomas with lymphovascular invasion should be offered adjuvant treatment with one cycle of BEP. The BEP regimen remains standard of care for metastatic disease, while the role of primary high-dose chemotherapy in case of inadequate tumor-marker decline or presence of high-risk features (i.e. mediastinal origin, non-pulmonary visceral metastases) remains to be elucidated. Several curative salvage chemotherapy combinations are available, i.e. TIP, VeIP, GIP or HD-CE. GOP is the current option of choice in cisplatin-refractory patients. Novel targeted agents failed to improve treatment outcome so far.
