    Serum levels of apoptosis - related markers (P53, BCL-2, SFAS-L, CASPASE-9) in copd patients

    Full text link
    Apoptosis is a complex process of regulated and programmed cell death. In this process, the activation of many genes and signaling pathways is involved. Apoptosis provides a protective function due to the elimination of autoreactive immune cells and thus limits the destruction of their own cells and tissues. Of great interest is the study of the influence of apoptosis on a variety of pathological processes

    Predictive value of <sup>18</sup>F-FDG accumulation in visceral fat activity to detect epithelial ovarian cancer metastases

    Epithelial ovarian cancer (EOC) is the most lethal gynecological malignancy, with relapse occurring in about 70% of advanced cases with poor prognosis. The study aimed to assess functional visceral fat activity (VAT) evaluated by 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) as a predictor of metastases in epithelial ovarian cancer. Methods: We assessed 53 patients with histologically confirmed EOC who underwent 18F-FDG PET/CT after a surgical treatment and courses of chemotherapy. Age, histology, stage, and tumor grade were recorded. Functional VAT was measured by maximum standardized uptake value (SUVmaJ using 18F-FDG PET/CT and tested as a predictor of later metastases in eight abdominal locations and pelvis cavity in the adjusted regression models. We also identified the best areas under the curve (AUC) for SUVmx with the corresponding sensitivity (Se) and specificity (Sp). Results: In both adjusted for regression models and ROC analysis, 18F-FDG accumulation in RE (cut-off SUVmax 1.18; Se 64%; Sp 64%; AUC 0.669; p=0.035) could predict later metastases in EOC patients, as opposed to age, sex, primary tumor location, tumor grade, and histology. Conclusions: VAT SUVmx is significantly associated with later metastases in EOC patients and can be used as their predictor.ΠΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½ΠΎΡΡ‚ΡŒ: Π­ΠΏΠΈΡ‚Π΅Π»ΠΈΠ°Π»ΡŒΠ½Ρ‹ΠΉ Ρ€Π°ΠΊ яичников (Epithelial Ovarian Cancer, EOC) являСтся Π½Π°ΠΈΠ±ΠΎΠ»Π΅Π΅ злокачСствСнным гинСкологичСским Π½ΠΎΠ²ΠΎΠΎΠ±Ρ€Π°Π·ΠΎΠ²Π°Π½ΠΈΠ΅ΠΌ, Ρ€Π΅Ρ†ΠΈΠ΄ΠΈΠ² ΠΊΠΎΡ‚ΠΎΡ€ΠΎΠ³ΠΎ происходит ΠΏΡ€ΠΈΠΌΠ΅Ρ€Π½ΠΎ Π² 70Β°% Π·Π°ΠΏΡƒΡ‰Π΅Π½Π½Ρ‹ΠΉ: случаСв ΠΈ отличаСтся нСблагоприятным ΠΏΡ€ΠΎΠ³Π½ΠΎΠ·ΠΎΠΌ.
