Uterus Sarcomas

BACKGROUND: Uterine sarcomas are uncommon mesenchymal tumors of the uterus. The clinical problem is that the features of uterine sarcomas can sometimes mimic uterine fibroids. This study aims to investigate the clinical characteristics of patients with uterine sarcomas who were preoperative presenting mainly with uterine masses. METHODS: A retrospective analysis of patients who underwent gynecological surgery for uterine sarcomas at the Obstetrics & Gynecology Hospital of Fudan University, between January 2016 and December 2021...

OBJECTIVES: To analyze the impact of perioperative characteristics on the risk of recurrence in patients with uterine leiomyosarcomas. METHODS: A sub-analysis of the SARComa of the UTerus (SARCUT) study, which is a multicentric cross-sectional pan-European study that included 390 patients diagnosed with leiomyosarcoma, between 2001 and 2007. Perioperative factors related to risk of recurrence and survival were analyzed. RESULTS: The 5-year and 10-year disease-free survivals (DFS) were 46% and 55%, respectively...

Primary osteosarcoma of the uterus is an extremely rare pure heterologous sarcoma of the uterus. The relevant available information is limited to case reports. To date, only 31 cases of this type of cancer have been reported. Here, we report the first clinical experience with the administration of an immunotherapy-based combination regimen for multiple metastatic primary osteosarcomas of the uterus. The patient had undergone multiple treatments prior to this regimen, but her condition continued to progress...

BACKGROUND: High-complexity and low-prevalence procedures benefit from treatment by referral centers. The volume of cases necessary to maintain high training in the treatment of gynecologic sarcoma is currently unknown. This study aimed to determine differences in survival and recurrence as a function of the volume of patients treated per center. METHODS: The multicentric cross-sectional SARComa of the Uterus (SARCUT) study retrospectively collected cases of uterine sarcomas from 44 centers in Europe from January 2001 to December 2007...

OBJECTIVE: Malignant transformation of mature ovarian teratoma is a rare phenomenon, mainly occurring in postmenopausal period. Squamous cell carcinoma accounts for 80% of all malignant transformations. Sarcoma transformation is much less common and tends to imply a poorer prognosis and aggressiveness. CASE REPORT: We report a case of undifferentiated sarcoma with squamous cell carcinoma in a mature cystic teratoma of the ovary in a 36-year-old woman. The tumor shows epithelial and stromal components...

OBJECTIVES: Carcinosarcomas (CSs) are rare gynecological neoplasms seen in elderly females. These are composed of malignant epithelial and mesenchymal components, which appear as adenocarcinoma and high-grade sarcoma. Effusions are encountered uncommonly in CS. MATERIAL AND METHODS: The study focuses on the cytomorphology of 10 cases of metastatic CS in effusions. In 6 years, there were 10 (0.45%) cases of metastatic CS in effusion samples out of 2240 malignant effusion samples...

A 44-year-old woman with irregular vaginal bleeding for more than 10 days and a palpable mass in the lower abdomen was the subject of study. Ultrasound suggested a hypoechoic uterine mass, which was considered to be a myoma with mixed echogenicity in the uterine cavity. Scraping showed no abnormal findings. Imaging raised the possibility of tumors of adnexal origin invading the ureter. The patient then underwent an open hysterectomy, bilateral adnexal resection, pelvic lesion resection, and vascular lesion resection...

Leiomyosarcoma is an aggressive soft tissue sarcoma derived from the smooth muscle cells of the uterus. We tested the effect of Romina strawberry extract treatment on three-dimensional cultured uterine leiomyosarcoma cells. We established 3D cultures in agarose gel, where the cells seeded were able to form spheroids. We performed the observation and counting of the spheroids with a phase-contrast optical microscope, finding a decrease in the number of spheroids formed in the plates after 24 and 48 h treatment with 250 µg/mL of cultivar Romina strawberry extract...

Four coumarin-triazole hybrids were selected from our in house library and screened for cytotoxic activity on A549 (lung cancer), HepG2 (liver cancer), J774A1 (mouse sarcoma macrophage), MCF7 (breast cancer), OVACAR (ovarian cancer), RAW (murine leukaemia macrophage), and SiHa (uterus carcinoma) and their in vitro toxicity was assessed on 3T3 (healthy fibroblasts) cell lines. SwissADME pharmacokinetic prediction was performed. Effects on ROS production, mitochondrial membrane potential, apoptosis/necrosis and DNA damage were evaluated...

BACKGROUND Leiomyosarcoma is the most common uterine sarcoma. Leiomyosarcoma is classified into conventional leiomyosarcoma, epithelioid leiomyosarcoma, and myxoid leiomyosarcoma. Leiomyosarcomas with rhabdoid features have been rarely reported. Herein, we report a case of uterine leiomyosarcoma with rhabdoid features. CASE REPORT A 58-year-old Korean woman presented with acute abdominal pain. Computed tomography and magnetic resonance imaging of the pelvis revealed a large solid mass in the posterior wall of the uterus that extended to the uterine cervix...

INTRODUCTION: Endometrial stromal sarcoma (ESS) is a rare malignancy of uterine in middle aged women. There are numerous subtypes for ESS which share the same clinical picture of uterine bleeding and pelvic pain. Consequently, diagnosis and treatment modalities of LG-ESS with metastasis are challenging. However, both molecular and immunological study of samples can be useful. CASE PRESENTATION: In this case study, we report a 52-year-old woman presenting with the chief complaint of unusual uterine bleeding...

OBJECTIVE: To assess the impact of the lymph node dissection (LND) in the disease-free (DFS) and overall survival (OS) of the women treated surgically of uterine leiomyosarcoma (ULMS). MATERIAL AND METHODS: A multicentric retrospective study was conducted among European countries collecting patients diagnosed of uterine sarcoma (SARcoma of the UTerus - SARCUT study). A total of 390 ULMS were selected for the present study to compare patients who underwent LND and those who did not...

Endometrial stromal sarcomas (ESSs) are a rare form of uterine malignancy representing <10% of all uterine sarcomas and <1% of all primary malignant tumours of the uterus. Invasion of the vascular system by low-grade ESS has been reported in the literature. Here we report the first case of a high-grade ESS invading the pelvic and gonadal vein and extending through the inferior vena cava to the right atrium, the diagnostic challenges and multidisciplinary management of the case.

Leiomyosarcoma (LMS) is a rare, aggressive mesenchymal tumor with smooth muscle differentiation. LMS is one of the most common histologic subtypes of soft tissue sarcoma; it most frequently occurs in the extremities, retroperitoneum, or uterus. LMS often demonstrates aggressive tumor biology, with a higher risk of developing distant metastatic disease than most sarcoma histologic types. The prognosis is poor, particularly in patients with uterine disease, and there is a need for the development of more effective therapies...

Uterine endometrial stromal sarcomas (ESS) with YWHAE::NUTM2 gene fusions are typically morphologically high-grade tumors composed of atypical round cells, sometimes associated with a low-grade fibromyxoid component; they are currently included in the category of high-grade ESS (HGESS). We report 5 morphologically pure low-grade endometrial stromal tumors harboring YWHAE::NUTM2 fusions, including 1 endometrial stromal nodule (ESN) and 4 low-grade endometrial stromal sarcomas (LGESS), an association only occasionally reported previously...

Leiomyosarcoma commonly occurs in the abdomen, retroperitoneum, large blood vessels, and uterus[1]. Cardiac leiomyosarcoma is a rare and highly aggressive sarcoma. We reported a case of a 63-year-old male with pulmonary artery leiomyosarcoma. Transthoracic echocardiography showed a large 4.4×2.3 cm hypoechoic mass in the right ventricular outflow tract and pulmonary artery. Computed tomography pulmonary angiography showed a filling defect in a similar location. The initial impression was PE, but a tumor was not ruled out...

Tissue containment systems (TCS) are medical devices that may be used during morcellation procedures during minimally invasive laparoscopic surgery. TCS are not new devices but their use as a potential mitigation for the spread of occult malignancy during laparoscopic power morcellation of fibroids and/or the uterus has been the subject of interest following reports of upstaging of previously undetected sarcoma in women who underwent a laparoscopic hysterectomy. Development of standardized test methods and acceptance criteria to evaluate the safety and performance of these devices will speed development, allowing for more devices to benefit patients...

OBJECTIVES: The present study aimed to analyze of uterine smooth muscle tumors of uncertain malignant potential (STUMP) and the outcomes of patients with STUMP. MATERIAL AND METHODS: In this retrospective study, the data of patients diagnosed with STUMP in a single tertiary center between January 2005-January 2020 were reviewed. We assessed the demographic variables, treatment outcomes, time until recurrence, disease-free and overall survival of the patients. RESULTS: Twenty-five patients diagnosed with STUMP were included in the study...
