Stromal cell-derived factor-1 (SDF-1) predicts poor clinical outcomes of certain types of cancer. Furthermore, vascular endothelial growth factor (VEGF) promotes the growth and metastasis of solid tumors. The aim of the present study was to examine the expression of SDF-1 and VEGF in patients with synovial sarcoma and to determine their expression is correlated with unfavorable outcomes. Levels of SDF-1 and VEGF proteins were evaluated in 54 patients with synovial sarcoma using immunohistochemical and immunofluorescence staining...

Importance: Patients with soft tissue sarcoma are at risk for local recurrence and distant metastases despite optimal local treatment. Preoperative anthracycline plus ifosfamide chemotherapy improves outcome in common histological subtypes. Objective: To analyze whether the previously reported improvement in local progression-free survival by adding regional hyperthermia to neoadjuvant chemotherapy translates into improved survival. Design, Setting, and Participants: Open-label, phase 3 randomized clinical trial to evaluate the efficacy and toxic effects of neoadjuvant chemotherapy plus regional hyperthermia...

Background: Myxofibrosarcoma (MFS), formerly considered as a myxoid variant of malignant fibrous histiocytoma, is the most common sarcoma of the extremities in adults and is characterized by a high frequency of local recurrence. The clinical behavior of MFS is unpredictable and the efficacy of chemotherapy is still not well documented. Furthermore, given the relatively recent recognition of MFS as a distinct pathologic entity its cellular and molecular biology has still not been extensively studied in patient-derived preclinical models...

BACKGROUND: High-dose-rate brachytherapy (HDR-BT) and external-beam radiation therapy (EBRT) are two modalities used in the treatment of soft tissue sarcoma. Previous work at our institution showed early complications and outcomes for patients treated with HDR-BT, EBRT, or a combination of both radiation therapy modalities. As the general indications for each of these approaches to radiation therapy differ, it is important to evaluate the use of each in an algorithmic way, reflecting how they are used in contemporary practice at sites that use these treatments...

Pulmonary artery sarcomas (PAS's) are extremely rare malignant tumors that arise from the endothelial lining of the pulmonary arteries. On CT scans PAS's appear as intraluminal filling defects in the pulmonary arteries, mimicking pulmonary embolism (PE). Due to the similarities in radiographic features as well as in clinical presentation, PAS's are usually misdiagnosed as pulmonary embolism. Since PASs are F-18 FDG avid, F-18 FDG PET/CT scan is a useful imaging tool for differentiating between these two conditions, as shown in this case report...

Malignant peripheral nerve sheath tumors (MPNSTs) are highly aggressive Schwann cell (SC)-lineage-derived sarcomas. Molecular events driving SC-to-MPNST transformation are incompletely understood. Here, we show that human MPNSTs exhibit elevated HIPPO-TAZ/YAP expression, and that TAZ/YAP hyperactivity in SCs caused by Lats1/2 loss potently induces high-grade nerve-associated tumors with full penetrance. Lats1/2 deficiency reprograms SCs to a cancerous, progenitor-like phenotype and promotes hyperproliferation...

BACKGROUND: Cancer stem cells (CSCs) have been shown to resist chemotherapy and promote metastasis after cytotoxic therapies. We sought to determine if the expression of CSC markers (aldehyde dehydrogenase [ALDH], CD44, and epidermal growth factor receptor [EGFR]) predicted outcomes in soft-tissue sarcoma (STS) patients. METHODS: We queried an institutional database of 23 STS patients and evaluated immunohistochemical expression of CSC markers ALDH, CD44, and EGFR...

Primary pleomorphic sarcoma of the left atrium is a rare tumor. There is no actual evidence of the management of this pathological entity, so the main treatment is individualized, surgical management being the cornerstone of the treatment. We present a 78-year-old female who had a clinical picture of heart failure, documenting an atrial mass of the left atrium, with high-grade pleomorphic sarcoma revealed in histopathology. The tumor was surgical removed, with no clinical evidence of residual mass. The tumor recurred again within 3 years, to which the patient succumbed...

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...

BACKGROUND: Polycomb repressive complex 2 (PRC2; formed by EZH2, SUZ12, and EED protein subunits) and PRC1 (BMI1 protein) induce gene silencing through histone modification by H3K27me3. In the present study, we characterized the PRC expression pattern and its clinical implication in sarcoma. METHODS: Using immunohistochemistry, we analyzed PRC expression in 105 sarcoma patients with 5 subtypes: synovial sarcoma (n = 18), rhabdomyosarcoma (n = 28), Ewing sarcoma (n = 15), osteosarcoma (n = 30), and others (n = 14)...

Spindle cell lesions of the breast cover a wide spectrum of diseases ranging from reactive tumor-like lesions to high-grade malignant tumors. The recognition of the benign spindle cell tumor-like lesions (nodular fasciitis; reactive spindle cell nodule after biopsy, inflammatory pseudotumor/inflammatory myofibroblastic tumor; fascicular variant of pseudoangiomatous stromal hyperplasia) and tumors (myofibroblastoma, benign fibroblastic spindle cell tumor, leiomyoma, schwannoma, spindle cell lipoma, solitary fibrous tumor, myxoma) is crucial to avoid confusion with morphologically similar but more aggressive bland-appearing spindle cell tumors, such as desmoid-type fibromatosis, low-grade (fibromatosis-like) spindle cell carcinoma, low-grade fibrosarcoma/myofibroblastic sarcoma and dermatofibrosarcoma protuberans...

Endometrial stromal sarcomas (ESS) are rare and understudied gynecologic mesenchymal neoplasms. These tumors can be confused with many other gynecologic and nongynecologic tumors due to their variegated morphologic appearance and nonspecific immunohistochemical profile. ESS can express cytokeratin (CK) and, therefore, may be misdiagnosed as carcinoma especially in extrauterine locations and when recurrence/metastasis is present. In this study, we investigated the expression of a wide spectrum of CKs consisting of AE1/3, CAM 5...

Therapies targeting programmed death 1-(PD-1) or its ligand (PD-L1), promoting antitumor T-cell activity have been successfully introduced into clinical practice. Clinical response correlates with PD-L1 expression by tumor cells or immune cells within the tumor microenvironment. The PD-L1/PD-1 axis and tumor microenvironment has been rarely studied in high-grade sarcomas of soft tissue (hSTS), a group of rare, genetically heterogenous and clinically aggressive tumors. We examined PD-L1 protein and CD274/PD-L1 gene copy number variations in 128 primary resected, therapy-naive hSTS using immunohistochemistry and fluorescence-in-situ hybridization...

Pseudotumour is a benign inflammatory lesion. Mycobacterial spindle cell pseudotumour (MSP) is a rare pseudotumour. It is a benign proliferation of spindle-shaped histiocytes containing acid-fast mycobacterium, commonly reported in immunocompromised patients. MSP is usually associated with mycobacterium avium complex (MAC). Here, we present the case of a 38-year-old gentleman with acquired immune deficiency syndrome (AIDS) who presented with low-grade fever for 1-month duration. Clinically, he had generalised lymphadenopathy...

Tumors with Müllerian-like serous or mucinous phenotypes originating in the testis and its adnexa are rare neoplasms that have been increasingly recognized in recent years. Cystadenomas with or without ovarian-type stroma, borderline tumors, and adenocarcinomas are the main documented types. Although a handful cases of putative endometrioid adenocarcinomas have been reported, to our knowledge no case of endometrial stromal-type neoplasm has ever been reported in the literature. A 59-year-old man presented with a 2 cm left intrascrotal mass that was found on sonographic examination to arise from the epididymal tail with prominent vascularization...

INTRODUCTION: Soft tissue Sarcomas (STS) are rare malignances, with high mortality rates. Half of patients develop metastasis. The presence of isolated Circulating Tumor Cells (CTCs) and Circulating Tumor Microemboli (CTM) in the blood may be early markers of tumor invasion. EGF family receptors can also influence this process. OBJECTIVES: to quantify CTCs and identify CTM as well as the EGFR protein expression in these cells and correlate with clinical outcome in metastatic STS...
