What is special about germ cell tumors in the mediastinum

Germ cell tumors in the mediastinum are different from those in the reproductive system. Germ cell tumors in the mediastinum mainly include seminoma, choriocarcinoma, primary mediastinal endodermal sinus tumor, embryoma, etc. The malignant degree of these tumors is relatively high, and the treatment is mainly based on comprehensive treatment, such as surgery, radiotherapy, chemotherapy, etc. Except seminoma, the prognosis of other germ cell tumors is relatively poor, but if mediastinal germ cell tumors are detected early and can be completely removed by surgery, then it is still possible to achieve cure, but this situation is relatively rare.
