Germinoma and other intracranial germ cell tumors have distinct biological characteristics compared to the tumors of neuroepithelial origin. Germinoma is morphologically identical to seminoma, but isochromosome 12p which is a most common genetic event in testicular GCT is rarely seen in intracranial GCT.

They are often large and have a tendency to spread more quickly than the other type of germ cell tumor (i.e., seminoma type). A seminoma is a germ cell tumor of the testicle or, more rarely, the mediastinum or other extra-gonadal locations. It is a malignant neoplasm and is one of the most treatable and curable cancers, with a survival rate above 95% if discovered in early stages. Testicular seminoma originates in the germinal epithelium of the seminiferous tubules. About half of germ cell tumors of the testicles are seminomas. Treatment usually requires removal of one testicle.

They originate from cells that were meant to form sex cells (i.e., sperm or eggs).

The nongerminomatous or nonseminomatous germ-cell tumors (NGGCT, NSGCT) include all other germ-cell tumors, pure and mixed. The two classes reflect an important clinical difference. Compared to germinomatous tumors, nongerminomatous tumors tend to grow faster, have an earlier mean age at time of diagnosis ( around 25 years versus 35 years, in the case of testicular cancers ), and have a lower five-year survival rate.

Although they are made up of distinct histological entities, in general, they have similar radiographic appearances. Nonseminomatous germ cell tumors are cancerous tumors commonly found in the pineal gland in the brain, in the mediastinum, or in the abdomen. They originate from cells that were meant to form sex cells (i.e., sperm or eggs).

The 4 main types of non-seminoma tumors are embryonal carcinoma, yolk sac carcinoma, choriocarcinoma, … Non-Seminomas. This type of germ cell tumor usually occurs in men between their late teens and early 40s.

Two of the most common germ cell tumors are seminoma and nonseminoma. Seminomas make up about half of all germ cell tumors. They usually grow slowly.

There are two different categories of germ cell tumors: seminoma and non-seminoma. However, after chemotherapy miRNA levels remained elevated in patients harboring viable germ cell tumor in post-chemotherapy retroperitoneal lymph node dissection specimens. miR-371a-3p demonstrated the highest discriminative capacity for viable germ cell tumors (AUC 0.874, 95% CI 0.774-0.974, p <0.0001).
