What is the uterine sarcoma?

type of cancer in the uterus, uterine sarcoma arises in connective tissue or smooth muscles, unlike endometrium or uterine lining. Uterine sarcomas are relatively rare and include only about four percent of the uterus malignancies; Most of them are endometrial sarcomas. After menopause, uterine sarcoma is usually manifested. Treatment usually takes the form of surgical removal, radiation, chemotherapy and hormonal therapy.

Anatomically, the uterus consists of three layers. The innermost is the endometrium, the lining of the column epithelial tissue, which rests on a layer of connective tissue, a tree. Another layer is myometrium, made of smooth muscles, a type of muscle tissue in all organs of the body except the heart. Finally, the uterus is closed by perimetry, a serous membrane, which also consists of a layer of epithelial tissue and a layer of connective tissue. The uterine sarcoma affects either a tree or myometrium.

There are three main types of uterine sarcoma, classified according to the tissue from which they are basedOLI Some sarcomas of the uterus are not suitable for one of these groups. Endometrial string sarcomas arise from the strius of endometrium, which lies between endometrium and smooth muscles. Uterine leiomyosarcomas come from smooth muscles and uterine carcinosarcomas, also called malignant mixed Müllerian tumors, contain cancer cells of both the origin of the epithelium and the connective tissue. The uterine cancer is further divided into two types: homologous, which contain only tissues found in the uterus, and heterological, which contain other types of tissues including bone, cartilage or skeletal muscle.

Symptoms of uterine sarcoma include pelvic pain and pressure, abnormal vaginal discharge, including post-menopausal or otherwise unusual bleeding and swelling of a non-pre-prigate uterus. The diagnosis often begins with imaging techniques such as ultrasound, computer tomography (CT) or magnetic resonance imaging (MRI), but must be confirmed by the microscopic inspection of the tumor. If possible, this inspection can be doneby hysteroscopy, biopsy or dilation and kyrettage (D&C). In biopsy, a small part of the tumor is removed for examination, usually a needle. Hysteroscopy uses an endoscope, a tube with a light and a lens system, to observe the interior of the uterus. In dilation and kyrettage, the opening of the uterus is extended or extended and the tool is used to scrape cells for examination.

The prognosis for uterine sarcoma is usually not very good. The preference for treatment is the hysterectomy in which the entire uterus is removed. Radiation, chemotherapy and hormonal therapy are other available treatment if surgery is not possible for some reason.
