Ovarian cancer (OC) is the fifth cancer death cause in women worldwide. The malignant nature of this disease stems from its unique dissemination pattern. Epithelial-to-mesenchymal transition (EMT) has been reported in OC and downregulation of Epithelial cadherin (E-cadherin) is a hallmark of this process. However, findings on the relationship between E-cadherin levels and OC progression, dissemination and aggressiveness are controversial. In this study, the evaluation of E-cadherin expression in an OC tissue microarray revealed its prognostic value to discriminate between advanced- and early-stage tumors, as well as serous tumors from other histologies...

The immune receptor NKG2D is predominantly expressed on NK cells and T cell subsets and confers anti-tumor activity. According to the current paradigm, immune surveillance is counteracted by soluble ligands shed into the microenvironment, which down-regulate NKG2D receptor expression. Here, we analyzed the clinical significance of the soluble NKG2D ligands sMICA and sULBP2 in the malignancy-associated ascites of ovarian cancer. We show that high levels of sMICA and sULBP2 in ascites were associated with a poor prognosis...

A standard strategy against ascites, a common symptom observed in cirrhotic and cancer patients, includes restriction of sodium intake and use of a diuretic. Paracentesis is a widely applied method against refractory ascites that do not react to such treatment. However, emerging fatigue and hemodynamic instability are possibly attributable to a loss of protein included in ascites. Cell-free and Concentrated Ascites Reinfusion Therapy (CART) is also applied against refractory ascites. CART comprises three processes...

BACKGROUND: Epithelial ovarian cancer (EOC) is the leading cause of death from gynaecologic malignancies and has a poor prognosis due to metastasis. Drugs targeting the angiogenesis pathway significantly improve patient outcome. However, the key factors linking angiogenesis and metastasis have not been elucidated. In this study, we found Tie2 expressing monocytes (CD14(+)Tie2(+), TEMs) as key contributors to angiogenesis and metastasis of EOC. METHODS: Tissue slides were evaluated by immunofluorescence for the presence of total tissue macrophages and TEMs...

To date, the lack of chemo-naive cell models limited exploratory studies to define novel therapies for Burkitt lymphoma (BL). To obtain a useful tool for biological and translational studies for this tumor, we established the RALE051 cell line from the malignant ascitic fluid cells of a patient at initial diagnosis, not previously exposed to any treatment. The cell line was characterized by karyotyping, fluorescence in situ hybridization (FISH), single nucleotide polymorphism (SNP) array, immunohistochemistry, and RNA-Seq, revealing the persistence of biological and molecular features observed in the primary ascitic fluid, such as the cell morphology and immunophenotype, the occurrence of a t(8;22) translocation deregulating MYC, knock-out ID3 mutations in a compound homozygous state, and a mutated TP53...

Circulating cell-free DNA (ccfDNA) can be found in various body fluids, i.e., blood (serum and plasma), urine, pleural effusions, and ascites. While ccfDNA predominantly originates from physiological processes, a fraction might be related to pathological events, e.g., cancer. Aberrant DNA methylation, which is considered a hallmark of cancer, can be assessed accurately in ccfDNA. Consequently, DNA methylation testing in body fluids represents a powerful diagnostic tool in the clinical management of malignant diseases...

The exact role of malignant ascites in the development of intraperitoneal ovarian cancer metastases remains unclear. In this report we sought to establish if ascites can determine the efficiency of transmesothelial invasion of ovarian cancer cells, and, if so, whether the fluid generated by highly aggressive serous and undifferentiated tumors will promote the invasion more effectively than ascites from less aggressive clear cell and endometrioid cancers. The study showed that the invasion of ovarian cancer cells (SKOV-3 and primary cancer cells) across monolayered peritoneal mesothelial cells was elevated upon mesothelial cell exposure to fluid produced by serous and undifferentiated cancers, as compared with cells subjected to ascites from clear cell and endometrioid tumors...

RATIONALE: Coexistence of lung adenocarcinoma and polyserous effusions is quite rare. This complexity of etiology adds difficulty to the diagnosis and is likely to cause misdiagnosis and maldiagnosis. PATIENT CONCERNS: A 43-year-old woman was admitted with symptoms of dry cough, chest suffocation, polyserous effusions, and generalized edema. Only a small number of heterocysts were detected in the ascites, and malignant cells were detected in the pleural and pericardial effusions...

Interactions between ovarian cancer cells and the surrounding tumor microenvironment are not well characterized. Here, we investigated the molecular mechanisms by which malignant ascites promote the metastasis of ovarian cancer. It was found that ovarian cancer ascites promoted ovarian cancer cell migration which was attenuated by either heat inactivation or antibody blockade of TGF-β. High level (at ng/ml level) of TGF-β was detected in the ascites. In addition, ascites repressed the expression of miRNA-125b in a TGF-β-dependent manner...

Chimeric antigen receptor (CAR) T cell therapy has shown limited efficacy for the management of solid tumor malignancies. In ovarian cancer, this is in part due to an immunosuppressive cytokine and cellular tumor microenvironment which suppresses adoptively transferred T cells. We engineered an armored CAR T cell capable of constitutive secretion of IL-12, and delineate the mechanisms via which these CAR T cells overcome a hostile tumor microenvironment. In this report, we demonstrate enhanced proliferation, decreased apoptosis and increased cytotoxicity in the presence of immunosuppressive ascites...

Aggressive systemic mastocytosis is a rare hematologic neoplastic disease that presents with a poor prognosis and low survival rate. It typically manifests with symptoms associated to mast cell release of bioactive substances, causing anaphylaxis, flushing, autonomic and hemodynamic instability, gastric distress and headache. Moreover, more than 95% of cases are related to a mutation in codon 816 of the KIT gene, located on human chromosome 4q12 which codes for a type III receptor tyrosine kinase. We present a 78 year-old Hispanic man diagnosed with the aggressive subtype of systemic mastocytosis, who had an atypical manifestation and a KIT negative variant...

Percutaneous image-guided ablation is performed throughout many areas of the body for various pathologies including hepatic malignancies. Heat and cold-based ablative technologies are effective and well-tolerated with an acceptable safety profile. However, ablative therapies may be technically more challenging and cause collateral thermal injury if the targeted lesion is adjacent to critical organs. Previously, techniques including artificial ascites and pneumoperitoneum have been utilized to displace or insulate critical structures from the ablation zone...
