Background: Uterine leiomyosarcoma (uLMS) is a rare tumor that accounts for 1% of all uterine malignancies. In spite of adequate surgical resection of uLMS, even in the early stage, patients remain at high risk for local and distant recurrence. Therefore, the treatment of advanced uLMS represents a considerable challenge. Methods: We report the case of a 47-year-old woman who presented with uLMS with abnormal vaginal bleeding. Results: The patient underwent a total hysterectomy and bilateral adnexectomy, which was followed by 1 year progression-free survival without adjuvant therapy...

BACKGROUND/AIM: Uterine leiomyosarcoma (uLMS) is a very rare mesenchymal tumor showing an aggressive clinical course and poor prognosis for patients. Due to the low incidence, little is known about molecular tumor biology and biomarkers of uLMS. Micro-RNA-1 (miR-1) has been identified as a pivotal tumor suppressor in numerous entities being suited as a molecular marker for tumor progression. MATERIALS AND METHODS: uLMS patient samples were analyzed regarding their miR-1 expression levels...

Uterine leiomyomas or uterine fibroids are the most common gynaecological tumours and occur in about 20-50% of women around the world. Ultrasonography (USG) is the first-line imaging examination in suspected fibroids and shows high sensitivity and specificity in diagnosing this condition. Ultrasound scans can be performed transvaginally (transvaginal scan - TVS) or transabdominally (transabdominal scan - TAS); both scans have advantages and limitations, but, in general, transvaginal sonography is superior to transabdominal sonography in most cases of pelvic pathology...

Cervical sarcomas are rare neoplasms, accounting for <1% of all cervical malignancies and characterized by an aggressive course despite radical excision. We report the clinical and microscopic features of a spindle cell sarcoma arising as a polypoid endocervical mass in a 45-yr-old woman. The neoplasm was characterized by a monotonous, mildly atypical proliferation of spindle cells, displaying a fibrosarcoma-like parallel pattern of highly dense fascicles, growing under the cervical epithelium. Mitotic activity was conspicuous, with up to 40 mitoses per 10 HPF...

Epigenetic events and genetic alterations under the control of the tumor microenvironment potentially mediate tumor induced angiogenesis involved in soft tissue sarcoma (STS) metastasis. Addition of antiangiogenic agent, such as bevacizumab, to standard chemotherapy in treatment of sarcoma has been studied in clinical trials, but most of the findings have not supported its use. We hypothesized the existence of an epigenetically mediated "angiogenic switch", and the tumor microenvironment, prevents bevacizumab from truly blocking angiogenesis...

Uterine sarcomas (US) are rare mesenchymal tumours of the uterus and are divided mainly into uterine leiomyosarcoma (uLMS), low grade endometrial stromal sarcoma (LG-ESS), high grade endometrial stromal sarcoma (HG-ESS), adenosarcomas and high grade undifferentiated sarcoma (HGUS). US are often high-grade tumours with a high local recurrence rate and metastatic risk. We here discuss the current standard of care and knowledge of systemic therapy for adult uterine sarcomas, in particular uLMS, LG-ESS, HG-ESS and HGUS, in both the adjuvant as well as the metastatic setting...

Uterine leiomyosarcoma (uLMS) is a rare disease; in the data from the SEER database, 3165 cases of uLMS were diagnosed between January 2000 and December 2012. While a majority of patients (60%) are diagnosed with early stage disease, recurrence rates are high. Five-year disease-specific survival is 76% for patients with FIGO stage I and 60% for patients with FIGO stage II disease. Adjuvant treatments, including radiation therapy, chemotherapy, and combined modality approaches, have been explored with the goal of demonstrating improved survival...

Uterine carcinosarcoma, also known as Malignant Mixed Müllerian Tumour, is a high-grade biphasic neoplasm composed of sarcomatous elements thought to originate via transdifferentiation from high-grade endometrial carcinoma. To identify molecular factors contributing to the histogenesis of this tumour, we analyzed DNA extracted from matched carcinoma and sarcoma components from 12 cases of carcinosarcoma by a molecular inversion probe microarray to assess genomic copy number alterations (CNAs) and allelic imbalances...

Leiomyosarcomas account for ~24% of all adult sarcomas, and develop predominantly either in the uterus [uterine leiomyosarcoma (ULMS)] or in deep soft tissue or the retroperitoneum [non-uterine leiomyosarcoma (NULMS)]. Leiomyosarcomas are relatively chemoresistant tumors, and the prognosis of patients with leiomyosarcomas is poor. Cancer-testis (CT) antigens are considered promising immunotherapeutic targets because of their restricted expression in normal tissue, except in the testis. Little is known about the expression of CT antigens in leiomyosarcomas...

Objective: Primary uterine leiomyosarcomas (ULMS) are rare, and the optimal treatment is controversial. We aimed to assess the outcome and prognostic factors in a multicenter population of women treated for primary ULMS. Methods: We retrospectively collected data of 110 women treated in 19 institutions of the Rare Cancer Network (RCN). Inclusion criteria consisted of a pathology report confirming the diagnosis of ULMS, aged 18-80 years, complete International Federation of Gynecology and Obstetrics (FIGO) stage information, complete information on treatment, and a minimum follow-up of 6 months...

Hereditary leiomyomatosis and renal cell carcinoma (HLRCC) syndrome is a rare autosomal dominant disease caused by germline mutations in the fumarate hydratase (FH) gene. Affected individuals develop cutaneous and uterine leiomyomas and aggressive RCC. To date, only few publications described the frequency and morphology of FH-deficient uterine leiomyomas. We reviewed 22 cases collected over 8 years from routine and consultation files based on distinctive histological features. In addition, we screened 580 consecutive uterine leiomyomas from 484 patients, 23 extra-uterine and 8 uterine leiomyosarcomas, and 6 leiomyomas with bizarre nuclei for FH loss using immunohistochemistry (IHC) on tissue microarrays (TMAs)...

The diagnosis of a uterine smooth muscle lesion is, in the majority of cases, straightforward. However, in a small number of cases, the morphological criteria used in such lesions cannot differentiate with certainty a benign from a malignant lesion and a diagnosis of smooth muscle tumor with uncertain malignant potential (STUMP) is made. Uterine leiomyosarcomas are often easy to diagnose but it is difficult or even impossible to identify a prognostic factor at the moment of the diagnosis with the exception of the stage...

OBJECTIVE: The objective of this study was to investigate the clinicopathological features and factors associated with recurrence in patients with uterine smooth muscle tumor of uncertain malignant potential (STUMP). METHODS: Forty-six cases diagnosed between 2000 and 2014 from 2 tertiary centers underwent blind slide review. Initial diagnosis included smooth muscle tumors with equivocal diagnosis, STUMPs, and cases that were named as leiomyosarcomas (LMS) or low-grade LMS despite not fulfilling the Stanford criteria...
