By using T2*-weighted imaging, MRI is able to differentiate distinguishing features of leiomyomas from uterine sarcomas. [2] Investigations by the physician include imaging (ultrasound, CAT scan, MRI) and, if possible, obtaining a tissue diagnosis by biopsy, hysteroscopy, or D&C. Ultimately the diagnosis is established by the histologic ...
The prognosis for low-grade endometrial stromal sarcoma is good, with 60–90% five-year survival. High-grade undifferentiated endometrial sarcoma (HGUS) has a worse prognosis, with high rates of recurrence and 25% five-year survival. [55] HGUS prognosis is dictated by whether or not the cancer has invaded the arteries and veins.
A diagnosis of uterine sarcoma may be suspected based on symptoms, a pelvic exam, and medical imaging. [2] Endometrial cancer can often be cured while uterine sarcoma typically is harder to treat. [3] Treatment may include a combination of surgery, radiation therapy, chemotherapy, hormone therapy, and targeted therapy.
Endometrial stromal tumours are a type of mesenchymal tumor of the main body of the uterus. [1] Types include endometrial stromal nodule , the distinct low and high-grade endometrial stromal sarcomas , and undifferentiated uterine sarcoma.
Endometrial Stromal Sarcoma, High-Grade. Undifferentiated uterine sarcoma, or undifferentiated (high-grade) endometrial stromal sarcoma, does not resemble normal endometrial stroma and behaves much more aggressively, frequently metastasizing. The differential includes leukemia, lymphoma, high-grade carcinoma, carcinosarcoma, and differentiated ...
Uterine serous carcinoma is a malignant form of serous tumor that originates in the uterus. It is an uncommon form of endometrial cancer that typically arises in postmenopausal women. It is typically diagnosed on endometrial biopsy , prompted by post-menopausal bleeding .
A leiomyosarcoma (LMS) is a rare malignant (cancerous) smooth muscle tumor. [1] The word is from leio- 'smooth' myo- 'muscle' and sarcoma 'tumor of connective tissue'. The stomach, bladder, uterus, blood vessels, and intestines are examples of hollow organs made up of smooth muscles where LMS can be located; however, the uterus and abdomen are the most common sites.
Endometrial intraepithelial neoplasia (EIN) is a premalignant lesion of the uterine lining that predisposes to endometrioid endometrial adenocarcinoma. It is composed of a collection of abnormal endometrial cells, arising from the glands that line the uterus , which have a tendency over time to progress to the most common form of uterine cancer ...
