The diagnostic potential of diffusion weighted and dynamic contrast enhanced MR imaging in the characterization of complex ovarian lesions

Publication date: September 2018Source: The Egyptian Journal of Radiology and Nuclear Medicine, Volume 49, Issue 3Author(s): Sally Emad-Eldin, Marie N. Grace, Manal H. Wahba, Rana M. AbdellaAbstractPurposeOur aim was to evaluate the diagnostic potential of diffusion-weighted (DW) and dynamic contrast enhanced MRI (DCE-MR) in the diagnosis and characterization of complex ovarian lesions.Patients and methodsWe prospectively evaluated 59 patients with 65 complex ovarian lesions detected at US. MRI examinations were performed using a 1.5 T MRI machine. Masses were classified as benign (n = 30), borderline (n = 7) and malignant (n = 28). Regions of interest were drawn and parameters were calculated such as apparent diffusion coefficient (ADC) values for the diffusion; maximum absolute enhancement (SI-max), maximum relative enhancement (MRE), time to peak (T-max) and wash-in-rate (WIR) for the dynamic parameters.ResultsThere was a significant difference in ADC values (P

In conclusion, the frequency of MCN is higher in middle-aged women, being the location in the distal pancreas and the percentage of malignancy is low. Laparoscopic surgery is a disease management option. PMID: 31967260 [PubMed - in process]

In conclusion, the combination of chemotherapy and glucose restriction was observed to decrease Ca-125 secretion and telomerase expression leading to shortening in telomere length. Thus, decreasing glucose availability for OC cells during treatment may lead to a better clinical outcome and potentially improve the prognosis of patients with OC. PMID: 31966066 [PubMed]

Authors: Hu J, Wang L, Zhao W, Huang Y, Wang Z, Shen H Abstract The present study aimed to investigate the involvement of long noncoding RNA mi-R4435-2HG in ovarian carcinoma. mi-R4435-2HG and Rho-associated protein kinase 2 (ROCK2) were demonstrated to both be upregulated in ovarian carcinoma. mi-R4435-2HG and ROCK2 were positively correlated in both tumor and healthy tissues. mi-R4435-2HG overexpression mediated the upregulation of ROCK2, while upregulation of ROCK2 did not affect mi-R4435-2HG. Overexpression of mi-R4435-2HG and ROCK2 led to promoted proliferation and inhibited apoptosis of cancer cells, while mi...

Cancer remains a leading cause of morbidity and mortality worldwide, requiring ongoing development of targeted therapeutics such as monoclonal antibodies. Carbohydrates on embryonic cells are often highly expressed in cancer and are therefore attractive targets for antibodies. Stage-specific embryonic antigen-4 (SSEA-4) is one such glycolipid target expressed in many cancers, including breast and ovarian carcinomas. Here, we defined the structural basis for recognition of SSEA-4 by a novel monospecific chimeric antibody (ch28/11). Five X-ray structures of ch28/11 Fab complexes with the SSEA-4 glycan headgroup, determined a...

Guanylate-binding protein 1 (GBP1) is a large GTPase of the dynamin superfamily involved in the regulation of membrane, cytoskeleton, and cell cycle progression dynamics. In many cell types, such as endothelial cells and monocytes, GBP1 expression is strongly provoked by interferon γ (IFNγ) and acts to restrain cellular proliferation in inflammatory contexts. In immunity, GBP1 activity is crucial for the maturation of autophagosomes infected by intracellular pathogens and the cellular response to pathogen-associated molecular patterns. In chronic inflammation, GBP1 activity inhibits endothelial cell proliferati...

Thalhammer Jäger High-grade serous ovarian cancer (HGSOC) is currently treated with cytoreductive surgery and platinum-based chemotherapy. The majority of patients show a primary response; however, many rapidly develop drug resistance. Antiestrogens have been studied as low toxic treatment options for HGSOC, with higher response rates in platinum-sensitive cases. Mechanisms for this difference in response remain unknown. Therefore, the present study investigated the impact of platinum resistance on steroid metabolism in six established HGSOC cell lines sensitive and resistant against carboplatin using a high-r...

Several studies have suggested that endometriosis is associated with an increased risk of ovarian cancer, especially for clear-cell and endometrioid subtypes. However previous studies lack sufficient power or diagnostic certainty.
