Advanced stage leiomyosarcoma (LMS) is incurable with current systemic antitumor therapies. Therefore, there is clinical interest in exploring novel therapeutic regimens to treat LMS. We reviewed the medical records of 75 consecutive patients with histologically confirmed metastatic LMS, who had been referred to the Clinical Center for Targeted Therapy at MD Anderson Cancer Center. To lay the foundation for potential phase I trials for the treatment of advanced LMS, we analyzed tumor response and survival outcome data...

It remains evident in the literature that leiomyosarcomas of the bladder have continuously been regarded as highly aggressive tumors associated with a poor prognosis. Immediate surgical therapy by radical cystectomy with wide margins is warranted as an effective treatment modality and has been associated with longer survival rates. Herein, we present the case of a high-grade leiomyosarcoma primarily treated with anterior pelvic exenteration and urinary diversion.

Leiomyomas are the most common neoplasm found in the uterus and can present with a variety of symptoms or be entirely asymptomatic. Most often, the characteristic imaging appearance of leiomyoma does not pose a diagnostic dilemma. However, leiomyomas can demonstrate atypical imaging features that may be confusing. It is essential for the radiologist to be aware of both the typical and atypical findings to better assist the referring clinician with diagnosis and management decisions. Additionally, as uterine-sparing treatment alternatives with locoregional therapies become more popular, it is important to be aware of pre- and post-procedural imaging questions that may be encountered...

BACKGROUND: Retroperitoneal sarcomas occur in an anatomically complex location often involving several adjacent organs. Surgery with multivisceral resection constitutes the mainstay of curative therapy. This study sought to characterise the morbidity and oncological outcomes of surgery for retroperitoneal sarcoma in an elderly population. METHODS: Patients with primary, localised retroperitoneal sarcoma referred between 1st January 2008 and 31st December 2014 were identified from multidisciplinary meeting records...

Patients with uterine leiomyosarcoma (LMS) typically present with vaginal bleeding, pain, and a pelvic mass, with atypical presentations of hypercalcemia and eosinophilia also being reported. Radiographic evaluation with combined positron-emission tomography/computed tomography may assist in diagnosis and surveillance in women with uterine LMS; these are commonly used with stage and tumour grade as prognostic indicators and a recently developed risk-assessment index to predict disease-specific survival. Recent studies have shown that the addition of adjuvant therapy after surgical management does not seem to improve survival, and ovarian preservation does not appear to negatively impact outcome...

BACKGROUND: Soft tissue sarcomas (STSs) overexpress vascular endothelial growth factors (VEGF) and VEGF-receptors (VEGFR) activation have been associated with tumor aggressiveness. Tivozanib is a potent small molecule tyrosine kinase inhibitor against VEGFR1-3, with activity against PDGFRα/β and cKIT. The primary endpoint of this study was progression free survival (PFS) rate at 16 weeks. Secondary end points were overall survival (OS), response rate, safety and correlative studies...

Uterine sarcoma is a very aggressive and highly lethal disease. Even after a comprehensive staging surgery or en block cytoreduction surgery followed by multimodality therapy (often chemotherapy and/or radiation therapy), many patients relapse or present with distant metastases, and finally die of diseases. The worst outcome of uterine sarcomas is partly because of their rarity, unknown etiology, and highly divergent genetic aberration. Uterine sarcomas are often classified into four distinct subtypes, including uterine leiomyosarcoma, low-grade uterine endometrial stromal sarcoma, high-grade uterine endometrial stromal sarcoma, and undifferentiated uterine sarcoma...

Uterine leiomyosarcoma (uLMS) is an aggressive malignancy characterized by its early metastasis, high rates of recurrence, and poor prognosis. Multiple obstacles complicate the clinical management of uLMS. These include the fact that most uLMS are typically identified only after a woman has undergone hysterectomy or myomectomy, the limited efficacy of adjuvant therapy for early stage disease, and the poor response of metastatic disease to current treatments. Here, we discuss recent insights into the molecular basis of uLMS and discuss emerging options for its clinical management...

BACKGROUND: Peritoneal sarcomatosis appears to be responding poorly to systemic chemotherapy. Treatment options traditionally include surgical ressections, chemotherapy and radiation therapy. Cytoreductive Surgery (CRS) and Hyperthermic Intraperitoneal Chemotherapy (HIPEC) offers a promising alternative locoregional treatment option. PATIENTS AND METHODS: We examine retrospectively 8 patients (4 females, 4 males) with peritoneal sarcomatosis. The most common histology type was the liposarcoma (4/8)...

There is only one previously reported incident in the English literature of sarcoma ex pleomorphic adenoma of the parotid and there are only 8 cases of primary parotid leiomyosarcoma. In our case, a 79-year-old female patient presented to our care with left preauricular pain, swelling, and facial weakness. After CT imaging, she underwent left total parotidectomy. A spindle cell lesion was identified intraoperatively and the facial nerve was sacrificed. Subsequent analysis of the lesion yielded a diagnosis of leiomyosarcoma ex pleomorphic adenoma...

Patients diagnosed with metastatic soft-tissue sarcoma (STS) have a poor prognosis. Additionally, after failure of first-line therapy, there are relatively few treatment options from which to choose. The novel tubulin-binding drug, eribulin, with a unique mechanism of action from taxanes or vinca alkaloids, has shown clinical activity in several different types of cancers. Eribulin has been approved by the US Food and Drug Administration (FDA) for patients with metastatic breast cancer previously treated with an anthracycline or a taxane and has recently been FDA approved for patients with unresectable or metastatic liposarcoma who have failed a previous anthracycline regimen...

Radiation-induced sarcomas (RIS) or postirradiation sarcomas have been reported as a rare long-term complication of radiation therapy (RT). The survival benefit offered by radiotherapy has been masked by an increase in the incidence of these sarcomas, thus making radiotherapy a double-edged sword. RIS generally develop with a mean latency period of 10-15 years and encompass different histological types. We report a case of oral leiomyosarcoma with a rather short latency period of 4 years after the radiotherapy of the prior oral squamous cell carcinoma (OSCC) detected on fluorine-18 (18F)-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography/computed tomography (PET/CT)...

A 48-year-old woman underwent a total abdominal hysterectomy after preoperative diagnosis of multiple uterine leiomyomas. The histopathological diagnosis was leiomyosarcoma (LMS). After 47 months, multiple lung metastases were detected and resected. The patient was also diagnosed with pelvic bone metastasis and received six cycles of adjuvant chemotherapy with gemcitabine plus docetaxel and local radiation therapy to control the pain. Seventy-seven months from the initial diagnosis, she had a headache and developed left hemiparesis and aphasia...

Sarcomas are rare uterine tumors with leiomyosarcomas and endometrial stromal sarcomas constituting the predominant entities often making their first appearance in young and middle-aged women. By histology combined with immunostaining alone some of these tumors can offer diagnostic challenges e.g. for the differential diagnosis between leiomyosarcomas and smooth muscle tumors of uncertain malignant potential (STUMP). Areas covered: Recent advances in the genetic classification and subclassification, respectively, have shown that genetic markers can offer a valuable adjunct to conventional diagnostic tools...

Uterine leiomyosarcoma (ULMS) is an aggressive tumor associated with high rates of progression, recurrence, and mortality. Pazopanib is the only approved molecular targeted drug for advanced soft tissue sarcoma, and it has been proven to prolong progression-free survival relative to placebo. We herein report a case of ULMS with multiple lung metastases treated with pazopanib, which led to sustained disease control for 44 weeks. A 53-year-old woman was referred to our hospital due to massive uterine bleeding from a uterine corpus tumor mass...

BACKGROUND: Stromal tumors of the digestive tract are uncommon malignant diseases, are subclassified as leiomyosarcomas and Gastrointestinal Stromal Tumors (GIST) depending on the molecular expression of tyrosine kinase receptor KIT (CD117). GISTs represent 1% of malignant tumors affecting this anatomical site. Localized tumours diseases are reasonably well controlled by surgical resection and several criteria define the need for adjuvant therapy. In the case of metastatic disease a poor prognosis has been reported with systemic treatment based on chemotherapy...

BACKGROUND: Retroperitoneal sarcoma is rare. Using initial specimens on biopsy, a definitive diagnosis of histological subtypes is ideal but not always achievable. METHODS: A retrospective institutional review was performed for all cases of adult retroperitoneal sarcoma from 1996 to 2015. A review of the literature was also performed related to the distribution of retroperitoneal sarcoma subtypes. A meta-analysis was performed. RESULTS: Liposarcoma is the most common subtype (45%), followed by leiomyosarcoma (21%), not otherwise specified (8%), and undifferentiated pleomorphic sarcoma (6%) by literature review...
