| Abstract: | This article has reviewed recent advances in understanding the molecular mechanisms of germ cell transformation, germ cell tumor differentiation, and germ cell tumor chemotherapy sensitivity and resistance. Future developments should include the following: The use of high-throughput techniques to assess tumor biology and evaluate new markers will allow more sophisticated assessment of prognosis. Future therapy will use oligonucleotide chips, perhaps specific to germ cell tumors or gene products associated with drug resistance, to assign treatment (radiation, RPLND, chemotherapy). The pathways associated with metastases and resistance will either replace or amplify the current risk algorithms and the clinician's ability to select therapy. The same high-throughput techniques will identify critical molecules and pathways, providing new specific treatment targets. Cell cycle-specific targets are an ideal focus of study, because genes abrogating normal cell cycle control and promoting germ cell tumorigenesis are increasingly identified. In germ cell tumors, CCND2 and KIT are open to study. Molecular and genetic markers of differentiation are additional resistance markers and should be a focus of study. In this context, the treatment of malignant transformation and the prediction of teratoma at metastatic sites will take on a greater importance. Over the past 2 decades, the treatment of germ cell tumors has become well-defined. Further improvement requires that investigators find new markers corresponding to tumor phenotype. This achievement will prevent unnecessary treatment in patients destined to have a favorable outcome, and will target biologically unfavorable or resistant disease for new therapy developed specifically to target the molecular or genetic defects that disrupt normal cell cycle control. |
