OBJECTIVE: In cancer patients, the pathology report serves as an important basis for treatment. Therefore, a correct cancer diagnosis is crucial, and diagnostic discrepancies may be of clinical relevance. It was the aim of this study to perform a specialized histopathology review and to investigate potential clinical implications of expert second opinion pathology in endometrial cancer. METHODS: Patients treated for endometrial carcinoma at the Tübingen University Women's hospital between 2003 and 2013 were identified...

PURPOSE: To investigate whether qualitative magnetic resonance (MR) features can distinguish leiomyosarcoma (LMS) from atypical leiomyoma (ALM) and assess the feasibility of texture analysis (TA). METHODS: This retrospective study included 41 women (ALM = 22, LMS = 19) imaged with MRI prior to surgery. Two readers (R1, R2) evaluated each lesion for qualitative MR features. Associations between MR features and LMS were evaluated with Fisher's exact test. Accuracy measures were calculated for the four most significant features...

Sarcomas arising from the chest wall account for less than 20% of all soft tissue sarcomas, and at this site, primitive tumors are the most frequent to occur. Leiomyosarcoma is a malignant smooth muscle tumor and the best outcomes are achieved with wide surgical excision. Although advancements have been made in treatment protocols, leiomyosarcoma remains one of the more difficult soft tissue sarcoma to treat. Currently, general local control is obtained with surgical treatment with wide negative margins. We describe the case of a 50-year-old man who underwent a chest wall resection involving a wide portion of the pectoralis major and minor muscle, the serratus and part of the second, third and fourth ribs of the left side...

A 38-year-old woman had developed an abdominal distention, lower extremity edema, and dyspnea. Imaging examination revealed a large mass in the right atrium which was connected to lesions within the inferior vena cava. Although complete resection of the mass was not possible, partial surgical tumor resection was performed to avoid pulmonary embolization and circulatory collapse. Leiomyosarcoma was diagnosed histologically, and chemotherapy (doxorubicin) followed by radiotherapy was started. By reviewing papers published in the past 10 years that included 322 patients, we also discuss the clinical presentations and prognosis of leiomyosarcoma in the inferior vena cava...

A 70-year-old man was referred to our department for further examination and treatment of a painless penile mass of about 2cm. The patient first noticed the mass onlya few weeks before presentation. Diagnostic biopsy was interpreted as leiomyosarcoma. Through systemic examinations the clinical stage of his disease was diagnosed as cT2N0M0 and we performed total penectomy. Histopathological examination for the totallyresected tissue disclosed the concomitant presence of regions compatible to squamous cell carcinoma and the results of immunohistochemistrywere compatible with the diagnosis of squamous cell carcinoma, sarcomatoid subtype of the penis...

While surgical resection (±radiotherapy) is standard treatment for localized soft tissue sarcomas (STS), chemotherapy is the mainstay for managing locally advanced and metastatic disease. Expanding knowledge of the biologies and sensitivities of STS histotypes, in conjunction with results from a growing collection of retrospective reviews and prospective randomized studies, point to the importance of treating in consideration of histological subtype. Doxorubicin ± ifosfamide continues to be standard first-line therapy for most STS subtypes...

PURPOSE: Highly aggressive adult soft tissue sarcomas (STS), i.e., leiomyosarcomas (LMS) and undifferentiated pleomorphic sarcomas (UPS), present complex genomic anomalies and overall 5-year survival rates of 20 to 40%. Here, we aimed to identify new biomarkers that may be employed to improve the treatment of non-translocation STS patients. We validated 12 miRNAs implicated in tumor development using primary STS samples and selected miR-152 for further analysis in STS-derived cell lines...

Previous decision analyses demonstrate the safety of minimally invasive hysterectomy for presumed benign fibroids, accounting for the risk of occult leiomyosarcoma and the differential mortality risk associated with laparotomy. Studies published since the 2014 Food and Drug Administration safety communications offer updated leiomyosarcoma incidence estimates. Incorporating these studies suggests that mortality rates are low following hysterectomy for presumed benign fibroids overall, and a minimally invasive approach remains a safe option...

BACKGROUND: Hyperthermic isolated limb perfusion (HILP) is an effective neoadjuvant treatment to avoid amputation in patients with locally advanced extremity soft tissue sarcomas (STS). We aimed to investigate whether STS histological type plays a role in predicting clinical outcomes. METHODS: This study reports a retrospective analysis of 125 patients with limb threatening STS (liposarcoma, n = 41; malignant peripheral nerve sheath tumor, n = 20; leiomyosarcoma, n = 20; miscellany, n = 44), who underwent HILP from 1990 through 2015 at our institution...

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...

Primary leiomyosarcoma arising from the ovarian vein is extremely rare, with only 10 cases reported in the literature. We report on a case of leiomyosarcoma of the left ovarian vein in a 67-year-old woman who presented with abdominal discomfort. Pelvic ultrasound revealed a large, solid, irregular mass in close relation to the left ovary. The patient subsequently underwent a total hysterectomy with bilateral salpingo-oophorectomy. Histologically, the tumor was composed of interlacing fascicles of spindle cells with abundant eosinophilic cytoplasm, hyperchromatic nuclei, and prominent nucleoli...

Sino-nasal smooth muscle tumours of uncertain malignant potential (SMTUMP) are very rare neoplasms of mesenchymal origin with features in between a benign leiomyoma and a leiomyosarcoma. We report a rare case of SMTUMP in a 44-year-old woman, who presented with vague symptoms of pharyngitis. Nasal endoscopy revealed a smooth mass in left nasal cavity. Contrast-enhanced CT and MRI scans showed features likely to be inverted papilloma or olfactory neuroblastoma or meningioma. Excision was planned and intraoperatively, frozen section revealed a probable spindle cell lesion...

Retroperitoneal sarcomas are rare malignant neoplasms that are often diagnosed late because of their typical nonspecific symptomatology. Radical surgical resection, if possible given the local anatomical conditions, is the most important treatment modality. However, even if the surgery is feasible and successful, the prognosis of retroperitoneal sarcoma is not good. The most frequent type of recurrence is local recurrence, and radical surgical resection remains the most important treatment modality even in such cases...

Metabolites can be an important read-out of disease. The identification and validation of biomarkers in the cancer metabolome that can stratify high-risk patients is one of the main current research aspects. Mass spectrometry has become the technique of choice for metabolomics studies, and mass spectrometry imaging (MSI) enables their visualization in patient tissues. In this study, we used MSI to identify prognostic metabolite biomarkers in high grade sarcomas; 33 high grade sarcoma patients, comprising osteosarcoma, leiomyosarcoma, myxofibrosarcoma, and undifferentiated pleomorphic sarcoma were analyzed...

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.

: Accurate mitosis-counting, which is important in the diagnosis of uterine smooth muscle tumors (USMT), is often difficult and subjective. The mitosis-specific immunohistochemical marker phosphohistone H3 (PHH3) has been shown to be diagnostically useful but its expression, in relation to outcome, has not been thoroughly investigated. AIMS AND METHODS: PHH3 expression was evaluated on 55 leiomyosarcomas (LMSs), 26 smooth muscle tumors of uncertain malignant potential (STUMPs), 18 leiomyomas with bizarre nuclei (LBNs) and 12 leiomyomas (LMs)...
