  2. Germ cell tumor - Wikipedia

    en.wikipedia.org/wiki/Germ_cell_tumor

    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 with germinomatous tumors, nongerminomatous tumors tend to grow faster, have an earlier mean age at time of diagnosis (around 25 years versus 35 years, in ...

    en.wikipedia.org/wiki/Mediastinal_germ_cell_tumor

    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.

  4. Teratoma - Wikipedia

    en.wikipedia.org/wiki/Teratoma

    Teratomas belong to a class of tumors known as nonseminomatous germ cell tumor. All tumors of this class are the result of abnormal development of pluripotent cells: germ cells and embryonal cells. Teratomas of embryonic origin are congenital; teratomas of germ cell origin may or may not be congenital. The kind of pluripotent cell appears to be ...

  5. Embryonal carcinoma - Wikipedia

    en.wikipedia.org/wiki/Embryonal_carcinoma

    In the testis pure embryonal carcinoma is also uncommon, and accounts for approximately ten percent of testicular germ cell tumours. However, it is present as a component of almost ninety percent of mixed nonseminomatous germ cell tumours. The average age at diagnosis is 31 years, and typically presents as a testicular lump which may be painful.

  6. Germinoma - Wikipedia

    Dysgerminoma is the most common type of malignant germ-cell ovarian cancer. Dysgerminoma usually occurs in adolescence and early adult life; about 5% occur in prepubertal children. Dysgerminoma is extremely rare after age 50. It occurs in both ovaries in 10% of patients and, in a further 10%, a microscopic tumor is in the other ovary. [citation ...

    en.wikipedia.org/wiki/Ovarian_Germ_Cell_Tumors

    Ovarian germ cell tumors (OGCTs) are heterogeneous tumors that are derived from the primitive germ cells of the embryonic gonad, which accounts for about 2.6% of all ovarian malignancies. [1] There are four main types of OGCTs, namely dysgerminomas , yolk sac tumor , teratoma , and choriocarcinoma .

    en.wikipedia.org/wiki/AFP-L3

    AFP-L3% is the standard for quantifying the L3 isoform of AFP in serum of high risk chronic liver disease (CLD) patients. Studies have shown that AFP-L3% test results of more than 10% can be indicative of early HCC [citation needed] or early nonseminomatous germ cell tumor. [1]
