Tumeur de l'utérus
Résumé
Uterine cancer, also known as womb cancer, includes two types of cancer that develop from the tissues of the uterus. Endometrial cancer forms from the lining of the uterus, and uterine sarcoma forms from the muscles or support tissue of the uterus. Endometrial cancer accounts for approximately 90% of all uterine cancers in the United States. Symptoms of endometrial cancer include changes in vaginal bleeding or pain in the pelvis. Symptoms of uterine sarcoma include unusual vaginal bleeding or a mass in the vagina.
Risk factors for endometrial cancer include obesity, metabolic syndrome, type 2 diabetes, taking pills that contain estrogen without progesterone, a history of tamoxifen use, late menopause, and a family history of the condition. Risk factors for uterine sarcoma include prior radiation therapy to the pelvis. Diagnosis of endometrial cancer is typically based on an endometrial biopsy. A diagnosis of uterine sarcoma may be suspected based on symptoms, a pelvic exam, and medical imaging.
Endometrial cancer can often be cured while uterine sarcoma typically is harder to treat. Treatment may include a combination of surgery, radiation therapy, chemotherapy, hormone therapy, and targeted therapy. Just over 80% of women survive more than 5 years following diagnosis.
In 2015 about 3.8 million women were affected globally and it resulted in 90,000 deaths. Endometrial cancer is relatively common while uterine sarcomas are rare. In the United States, uterine cancers represent 3.5% of new cancer cases. They most commonly occur in women between the ages of 45 and 74 with a median age of diagnosis of 63.
The terms uterine cancer and womb cancer may refer to several different types of cancer that occur in the uterus, namely:
Endometrial carcinomas originate from cells in the glands of the endometrium (uterine lining). These include the common and readily treatable well-differentiated endometrioid adenocarcinoma, as well as the more aggressive uterine papillary serous carcinoma and uterine clear-cell carcinoma.
