Abstract:
Somatic-type malignancies (STMs) arising in germ cell tumors are relatively rare, affecting 3% to 8% of patients. These neoplasms show aggressive clinical behavior and are frequently resistant to systemic therapy. In the current review, we provide a comprehensive clinicopathologic overview of these tumors, emphasizing new molecular findings that have improved our understanding of their pathogenesis. In all areas, we highlight special considerations related to the different histologic subtypes. We conclude with a brief mention of areas of uncertainty and areas that require further study.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
