Testicular germ cell tumor (TGCT) is one of the most common malignancies among young men in many countries [ 1 ]. Histologically, TGCTs are divided into two major subtypes, seminoma (SE) and non-seminoma (NSE). In fact, 15% of TGCTs are mixed tumors that contain both SE and NSE elements [ 2 ].

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). They are often large and have a tendency to spread more quickly than the other type of germ cell tumor (i.e., seminoma type).

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). Non-Seminomas. This type of germ cell tumor usually occurs in men between their late teens and early 40s.

2021-04-14 · There are two main types of GCT: seminoma and nonseminomatous germ cell tumors (NSGCT). Both seminoma and NSGCT occur at about the same rate, and men can have seminoma, NSGCT or a combination of both. There are several differences between seminomas and NSGCT, but the initial distinction is based on how the tumor looks under the microscope. As a result, chemotherapy is the standard treatment for men with advanced seminoma or nonseminomatous germ cell tumors (NSGCTs) and for those with persistently elevated serum tumor markers following orchiectomy.

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). Germ cell tumors that occur in places other than the testicles and ovaries (extragonadal germ cell tumors) are very rare.
