Serum tumor marker test: For GTN, the blood is checked for the level of β-hCG, a hormone that is made by the body during pregnancy. β-hCG in the blood of a woman who is not pregnant may be a sign of GTN and also helpful tests to monitor a woman’s recovery during and after treatment. Placental side trophoblastic tumor (PSTT) is ...
Gestational trophoblastic disease (GTD) is a term used for a group of pregnancy-related tumours. [1] These tumours are rare, and they appear when cells in the womb start to proliferate uncontrollably. The cells that form gestational trophoblastic tumours are called trophoblasts and come from tissue that grows to form the placenta during pregnancy.
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.
Bloating, abdominal distention, ascites, dyspareunia. 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 ...
Deaths. 161,100 (2015) [9] Ovarian cancer is a cancerous tumor of an ovary. [10] It may originate from the ovary itself or more commonly from communicating nearby structures such as fallopian tubes or the inner lining of the abdomen. [3][11] The ovary is made up of three different cell types including epithelial cells, germ cells, and stromal ...
Most mediastinal malignant tumors are large and cause symptoms by compressing or invading adjacent structures, including the lungs, pleura, pericardium, and chest wall. Seminomas grow relatively slowly and can become very large before causing symptoms. Tumors 20 to 30 cm in diameter can exist with minimal symptomatology.
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.
In the ovary, embryonal carcinoma is quite rare, amounting to approximately three percent of ovarian germ cell tumours. The median age at diagnosis is 15 years. Symptoms and signs are varied, and may include sexual precocity and abnormal (increased, reduced or absent) uterine bleeding. [1]
