Leiomyosarcomas (LMS) are rare sinonasal malignant tumours with 20 cases of nasal LMS previously reported in the literature. An 81-year-old man presented with an incidental left nasal lesion associated with left nasal obstruction and occasional left-sided blood-stained rhinorrhoea. Nasendoscopic examination showed green coloured polyps filling the left nasal cavity with biopsies showing LMS. CT imaging did not show any bony erosion. No metastases were found on positron emission tomography imaging. The patient underwent endoscopic resection and all surgical margins were clear of disease...

Uterine sarcomas are some of the most malignant and aggressive tumor types among the gynecologic malignancies, and they are associated with a high rate of recurrence and a poor prognosis. Due to their rarity and diversity, the optimal treatment for recurrent uterine sarcomas has not yet been elucidated. The aim of the present study was to investigate the potential of secondary cytoreductive surgery (SCS) for patients with recurrent uterine sarcomas. A total of 18 patients with recurrent uterine sarcomas were retrospectively identified at the Department of Obstetrics and Gynecology, Nagoya University (Nagoya, Japan) between January 2002 and December 2015...

Primary thyroid leiomyosarcoma (LMS) is an extremely rare tumor. We report a case of a 47-year-old male with a rapidly growing neck mass and disfagia. Preoperative investigations were diagnostic of anaplastic carcinoma. Total thyroidectomy with partial esophagectomy and dissection of right infrahyoid muscles was performed. Through histolological and immunohistochemical evaluations a primary thyroid high-grade LMS was diagnosed. At 2 months of follow-up a local recurrence was detected and consequently the patient was submitted to chemotherapy with partial response...

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: Over one-third of primary rectal cancers are locally advanced at diagnosis, and local recurrence of rectal cancer occurs at a rate of 3-10% following primary curative resection. Extended resectional surgery, including pelvic exenteration, is the only proven therapy with curative potential in the treatment of these cancers along with many other pelvic malignancies. A microscopically clear resection margin (R0 resection) is the predominant prognostic factor affecting overall and disease-free survival...

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...

LESSONS LEARNED: Ablation therapy appears to be a reasonably safe and effective approach to obtain a significant treatment-free interval for a subset of patients with limited sites of metastatic disease for which systemic control can be obtained with six cycles of chemotherapy. BACKGROUND: Metastatic sarcoma often becomes resistant to treatment by chemotherapy. There is sometimes prolonged stable disease from active chemotherapy that provides a window of opportunity for an intervention to prolong disease-free survival...

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...

BACKGROUND: Leiomyosarcoma of the head and neck region is very rare. Primary parotid leiomyosarcoma has only been reported nine times in the medical literature. METHODS: A 68-year-old female presented with a left facial mass. Physical examination revealed a firm immobile mass at the level of the left parotid tail. No facial nerve dysfunction or palpable adenopathy was noted at the time of presentation. This patient underwent a superficial parotidectomy with a facial nerve dissection and left selective neck dissection...

A 60 year old woman who presented with multiple small subcutaneous nodules in the upper back and arms, was referred for an [18F] fluoro-2-deoxy-D-glucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) after histological evaluation revealed metastatic leiomyosarcoma of unknown origin. The PET/CT showed multiple 18F-FDG-avid subcutaneous nodules, bone lesions, as well as a large left renal mass, which was biopsied to confirm a primary renal leiomyosarcoma arising from the renal parenchyma...

Bone leiomyosarcoma is a rare primary osseous malignant tumor with a high metastatic potential. Similar to other bone sarcomas, high histological grade and tumor stage are predictive of a poor outcome. We herein present our experience with treating a 64-year-old woman with bone leiomyosarcoma accompanied by multiple bone metastases. A biopsy revealed occasional osteoclast-like giant cells. In addition to radiation therapy, the osteoclastogenesis inhibitor denosumab was administered but the patient did not undergo adjuvant chemotherapy or surgery...

BACKGROUND AND OBJECTIVES: Primary liver sarcomas (PLS) are rare. Published series are limited by small numbers of patients. METHODS: We reviewed the National Cancer Database (2004-2014) for patients who underwent surgical resection of PLS. RESULTS: Of 237 patients identified, the majority were female (60.8%), with median age of 52 years. Histologies were: epithelioid hemangioendothelioma (n = 67), angiosarcoma (n = 64), leiomyosarcoma (n = 33), embryonal rhabdomyosarcoma (n = 31), carcinosarcoma (n = 16), giant cell sarcoma (n = 14), spindle cell sarcoma (n = 12)...

Primary intracranial leiomyosarcoma (LMS) is an extremely rare tumor of the central nervous system. Only sporadic case reports have been published, and therefore data regarding long-term prognosis remain scarce. A 76-year-old woman presented with a right parietal mass, which had grown rapidly in the month prior to admission. Neuroimaging showed a resemblance to intraosseous meningioma. Gross total resection of the tumor was achieved, and histological diagnosis confirmed LMS. Because positron emission tomography (PET) with fluorodeoxyglucose (FDG) just after the resection showed no abnormal uptake, we diagnosed the tumor as primary intracranial LMS...

Leiomyosarcoma (LMS) is an aggressive mesenchymal malignancy with few therapeutic options. The mechanisms underlying LMS development, including clinically actionable genetic vulnerabilities, are largely unknown. Here we show, using whole-exome and transcriptome sequencing, that LMS tumors are characterized by substantial mutational heterogeneity, near-universal inactivation of TP53 and RB1, widespread DNA copy number alterations including chromothripsis, and frequent whole-genome duplication. Furthermore, we detect alternative telomere lengthening in 78% of cases and identify recurrent alterations in telomere maintenance genes such as ATRX, RBL2, and SP100, providing insight into the genetic basis of this mechanism...

Pulmonary embolism (PE) is usually caused by thrombosis or tumor. We report the long-term survival of a patient with PE due to a leiomyosarcoma in the deep vein. A 71-year-old woman complained of dyspnea and swelling of the left lower limb. Computed tomography revealed filling defects in the pulmonary arteries and deep vein. She was diagnosed with PE caused by venous thrombosis and treated with anticoagulant therapy. Her symptoms were prolonged, and D-dimer tests remained negative. Biopsy of the substance in the deep vein revealed leiomyosarcoma...
