The treatment for mediastinal nonseminomatous germ cell tumors should follow guidelines for poor-prognosis testicular cancer. Initial treatment with four courses of bleomycin, etoposide, and cisplatin, followed by surgical resection of any residual disease, is considered standard therapy.
A mediastinal tumor is a tumor in the mediastinum, the cavity that separates the lungs from the rest of the chest. It contains the heart , esophagus , trachea , thymus , and aorta . The most common mediastinal masses are thymoma (20% of mediastinal tumors), usually found in the anterior mediastinum, followed by neurogenic Timor (15–20% ...
Choriocarcinoma is a malignant, trophoblastic [1] cancer, usually of the placenta. It is characterized by early hematogenous spread to the lungs. It belongs to the malignant end of the spectrum in gestational trophoblastic disease (GTD). It is also classified as a germ cell tumor and may arise in the testis or ovary.
Thymoma and Thymic carcinoma: These tumors which arise from the thymus gland in the upper part of the chest overlying the heart, can seed the pleural surfaces in addition to invading the lung and other structures. [2] [3] Mesothelioma: A benign (noncancerous) or malignant (cancerous) tumor affecting the lining of the chest or abdomen. Exposure ...
The 1997 International Germ Cell Consensus Classification [17] is a tool for estimating the risk of relapse after treatment of malignant germ-cell tumor. A small study of ovarian tumors in girls [18] reports a correlation between cystic and benign tumors, and conversely, solid and malignant tumors. Because the cystic extent of a tumor can be ...
Tumors with both seminoma and nonseminoma elements or that occur with the presence of AFP should be treated as nonseminomas. Abdominal CT or MRI scans as well as chest imaging are done to detect for metastasis. The analysis of tumor markers also helps in staging. [12] The preferred treatment for most forms of stage 1 seminoma is active ...
These rare forms of teratoma with malignant transformation may contain elements of somatic (not germ cell) malignancy such as leukemia, carcinoma, or sarcoma. [35] A teratoma may contain elements of other germ cell tumors, in which case it is not a pure teratoma, but rather is a mixed germ cell tumor and is malignant.
A mixed germ cell tumor in the testes. On the left side shows yolk sac tumor, and on the right side shows embryonal carcinoma. Under the classification of the biology GCT, there is a more detailed classification contains specific types of extracranial extragonadal germ cell tumor. There are two types, teratomas, and malignant GCTs.
