Testicular cancer is a rare cancer in the general population, but is the most common neoplasm among young men in many countries. It has one of the highest heritabilities of all cancer types. The vast majority of testicular cancers are germ cell tumors; thus the terms “testicular cancer” and “testicular germ cell tumors” (TGCTs) are often used interchangeably. Globally, the incidence of testicular cancer is highest among men of European ancestry and lowest among men of African and Asian ancestries. Incidence rates have been increasing in many countries since at least the mid-twentieth century. Mortality rates, however, have sharply declined in developed countries. While the reason for the decline in mortality rates is well known, reasons for the increase in incidence remain poorly understood. Accumulating evidence supports the hypothesis that most TGCTs are linked to disturbed development of the testes, beginning in utero, but fostered by postnatal events.

Testicular germ cell tumors (TGCTs) represent the most common malignancy in men aged 15-35. Due to these tumors’ biological and clinical characteristics, they can serve as an appropriate system for studying molecular mechanisms associated with cisplatin-based treatment resistance. This review describes treatment resistance from clinical and molecular viewpoints. Cisplatin resistance is determined by various biological mechanisms, including the modulation of the DNA repair capacity of cancer cells, alterations to apoptotic cell death pathways, deregulation of gene expression pathways, epigenetic alterations and insufficient DNA binding. Moreover, this review describes TGCTs as a model system that enables the study of the cellular features of cancer stem cells in metastatic process and describes experimental models that can be used to study treatment resistance in TGCTs. All of the abovementioned aspects may help to elucidate the molecular mechanisms underlying cisplatin resistance and may help to identify promising new therapeutic targets.

<b><i>Introduction:</i></b> The impact of teratomatous elements in orchiectomy specimens of metastasized testicular germ cell tumors (TGCT) regarding oncological outcome is still unclear. <b><i>Methods:</i></b> We performed a retrospective analysis including 146 patients with metastasized TGCT analysing patient characteristics. <b><i>Results:</i></b> Twenty-six (18%) of all patients showed teratomatous elements in the orchiectomy specimens. TGCT with teratomatous elements showed a significantly higher frequency of clinical-stage 2C-3 disease (73 vs. 49%, <i>p</i> = 0.031), visceral metastases (58 vs. 32%, <i>p</i> = 0.015), and poor prognosis (<i>p</i> = 0.011) than TGCT without teratomatous elements. Teratoma-containing TGCT revealed a significantly higher rate of post-chemotherapy retroperitoneal lymph node dissection (PC-RPLND, 54 vs. 32%, <i>p</i> = 0.041), with teratomatous elements being more often present in the PC-RPLND specimens (43 vs. 11%, <i>p</i> = 0.020) than nonteratoma-containing primaries. In the Kaplan-Meier estimates, the presence of teratomatous elements in orchiectomy specimens was associated with a significantly reduced relapse-free survival (RFS) (<i>p</i> = 0.049) during a median follow-up of 36 months (10–115.5). <b><i>Conclusions:</i></b> The presence of teratomatous elements in orchiectomy specimens is associated with an advanced tumor stage, worse treatment response as well as a reduced RFS in metastasized TGCT. Consequently, the presence of teratomatous elements might act as a reliable stratification tool for treatment decision in TGCT patients.
