Carbon dioxide (CO2) therapy can be applied to treat a variety of disorders. We previously found that transcutaneous application of CO2 with a hydrogel decreased the tumor volume of several types of tumors and induced apoptosis via the mitochondrial pathway. However, only one condition of treatment intensity has been tested. For widespread application in clinical antitumor therapy, the conditions must be optimized. In the present study, we investigated the relationship between the duration, frequency, and treatment interval of transcutaneous CO2 application and antitumor effects in murine xenograft models...

We report the case of a 57-year-old female suffering from recurrent malignant undifferentiated pleomorphic sarcoma of the left atrium. Metastasis to the posterior mediastinum was detected upon first presentation. Incomplete resections were carried out twice before mitral valve replacement was finally performed. The tumor recurred 16 months later and was treated with radiation therapy, which has proved to be effective in bringing about tumor regression for 2 years, to date. The patient has survived for 7 years since the first surgery...

BACKGROUND: The European Organization for Research and Treatment of Cancer (EORTC) 62012 study was a Phase III trial of doxorubicin versus doxorubicin-ifosfamide chemotherapy in 455 patients with advanced soft tissue sarcoma (STS). Analysis of the main study showed that combination chemotherapy improved tumor response and progression-free survival, but differences in overall survival (OS) were not statistically significant. We analyzed factors prognostic for tumor response and OS, and assessed histological subgroup and tumor grade as predictive factors to identify patients more likely to benefit from combination chemotherapy...

RATIONALE: An intracardiac cystic mass is a rare type of mass found in the left atrium. The differential diagnosis of an intracardiac cystic mass includes hydatid cysts, bronchogenic cysts, intracardiac varices, and hemorrhages in some tumor types, including myxoma. PATIENT CONCERNS: We present the case of a 68-year-old woman who presented with episodic dyspnea. DIAGNOSES-INTERVENTIONS-OUTCOMES: Transthoracic echocardiography (TTE) revealed the presence of a left atrial mass mimicking myxoma...

Soft-tissue sarcomas (STS) are rare malignancies that account for 1% of adult cancers and comprise more than 50 entities. Current therapeutic options for advanced-stage STS are limited. Immune checkpoint inhibitors targeting the PD-1/PD-L1 signaling axis are being explored as new treatment modality in STS; however, the determinants of response to these agents are largely unknown. Using the sarcoma data set of The Cancer Genome Altas (TCGA) and an independent cohort of untreated high-grade STS, we analyzed DNA copy number status and mRNA expression of PD-L1 in a total of 335 STS cases...

BACKGROUND AND AIM: Sarcomas are of mesenchymal origin and typically show abundant tumour stroma and presence of necrosis. In search for novel biomarkers for personalised therapy, we determined the prognostic impact of stromal markers, hypoxia and neovascularity in high-grade soft tissue leiomyosarcoma and pleomorphic undifferentiated sarcoma. METHOD: We evaluated CD163, colony-stimulating factor (CSF)-1, CD16 and hypoxia-inducible factor 1 (HIF-1)α using immunohistochemical staining and assessed microvessel density using CD31 in 73 high-grade leiomyosarcomas and undifferentiated pleomorphic sarcomas of the extremities and the trunk wall...

Anaplastic large cell lymphoma (ALCL) is a T-cell lymphoma which has been recognized to have a variable clinical presentation and a broad spectrum of histomorphologic features. Its variable histomorphologic appearances are sometimes diagnostically challenging for the pathologists since they can mimic sarcomas, melanomas and undifferentiated carcinomas. To our knowledge, a previous case of axillary soft-tissue mass of ALK-positive ALCL with an alveolar growth pattern has been so far reported in the literature...

There have been several updates recently on the classification of uterine tumors. Endometrial carcinomas have traditionally been divided into 2 types, but some are difficult to classify and do not fit readily into either of the currently recognized categories. The Cancer Genome Atlas Research Network has recently defined 4 new categories of endometrial cancer on the basis of mutational spectra, copy number alteration, and microsatellite instability, which might provide independent prognostic information beyond established risk factors...

BACKGROUND: The risk of local recurrence (LR) after soft tissue sarcoma (STS) resection is higher in the setting of inadvertent positive margins (IPMs). This study assessed whether both tumor- and surgery-related factors contribute to IPMs, and whether tumor- versus surgery-related IPMs differ in LR or overall survival (OS). METHODS: Retrospective review of a tertiary center database identified patients with IPMs following STS resection between 1989 and 2014. Of 2234 resected STSs, 309 (13%) had positive margins; 89 (4%) were IPMs...

A patient-derived orthotopic xenograft (PDOX) model of undifferentiated pleomorphic sarcoma (UPS) was previously established that acquired red fluorescent protein (RFP)-expressing stroma by growth in an RFP transgenic nude mouse. In the present study, an imageable PDOX model (iPDOX) of UPS was established by orthotopic implantation in the biceps femoris of transgenic RFP nude mice. After the tumors grew to a diameter of 10 mm, they were harvested and the brightest portion of the tumors were subsequently orthotopically transplanted to both RFP and non-colored nude mice...

BACKGROUND: Undifferentiated high-grade pleomorphic sarcoma in gastrointestinal tract is extremely rare, and its prognosis is poor. CASE PRESENTATION: An 82-year-old man visited a previous hospital complaining of fever, general fatigue, and shaking chill, for which he received antibiotics therapy. As the fever continued, he was referred to our hospital, where computed tomography and upper gastrointestinal endoscopy showed a 6-cm gastric tumor. A preoperative biopsy was consistent with a malignant mesenchymal tumor, but could not provide a definitive pathological diagnosis nor prove a cause-and-effect relationship between the chief complaint and the gastric tumor...

Giant cell tumor of bone (GCT) is a locally aggressive, rarely metastasizing primary bone neoplasm that occurs most frequently in the epiphysis of long bones of young adults. It is composed of round, oval or elongated mononuclear cells admixed with osteoclast-like giant cells that express receptor activator of nuclear factor- қB (RANK). The mononuclear stromal cells express RANK ligand (RANKL), a mediator of osteoclast activation. Denosumab, a monoclonal antibody that inhibits RANKL reducing tumor-associated bone lysis, has been used to treat selected cases of GCT...

Soft tissue sarcomas of the esophagus represent an extremely rare cause of esophageal masses, and an even smaller proportion of these tumors represent dedifferentiated liposarcomas. We present a case of a 75-year-old gentleman presenting with dysphagia found to have a 5 cm pedunculated mass in the cervical esophagus, originating at the cricopharyngeus. This was found to have involvement limited to the superficial mucosa by endoscopic ultrasound, and the lesion was subsequently resected endoscopically. Pathology demonstrated an undifferentiated pleomorphic sarcoma later determined to represent dedifferentiated liposarcoma after fluorescence in situ hybridization analysis...

CIC-rearranged sarcoma is a new entity of undifferentiated small round cell sarcoma characterized by chimeric fusions with CIC-rearrangement. We report a NUTM2A-CIC fusion sarcoma in a 43-year-old woman who died of rapidly progressive disease. Histologic analysis revealed multinodular proliferation of small round tumor cells with mild nuclear pleomorphism. The sclerotic fibrous septa separated the tumor into multiple nodules. Immunohistochemistry showed that the tumor cells were diffusely positive for vimentin, focally positive for cytokeratin, and negative for CD99 and NKX2...

Malignant fibrous histiocytoma is a sarcoma with rare occurrence in the oral and maxillofacial region; surgery is the most reliable treatment. Inadequate resection of the sarcoma on the oral and maxillofacial region is associated with a high incidence of local recurrence and a poor prognosis. Only few patients of malignant fibrous histiocytoma of the malar region have been previously reported in the literature. The authors report a new patient of malignant fibrous histiocytoma on the right malar region that treated a complete tumor surgical excision without lymph node dissection...
