چکیده

مقدمه: یکی از فاکتورهای مؤثر در آنژیوژنز و گسترش سلول‌های توموری، فاکتور رشد سلول‌های اندوتلیال عروقی (Vascular endothelial growth factor  یا VEGF) است. این فاکتور همچنین از طریق افزایش در نفوذپذیری عروقی در تشکیل ترشحات سروزی نظیر آسیت یا پلورال افیوژن نیز مؤثر است. اما تشخیص و افتراق مایعات سروزی بدخیم از موارد خوش‌خیم همواره به عنوان یک مشکل مطرح بوده است. بنابراین مطالعه‌ی حاضر با هدف بررسی سطح و ارزش تشخیصی VEGF در افتراق مایعات سروزی بدخیم از مایعات سروزی خوش‌خیم انجام شد.روش‌ها: مطالعه‌ی حاضر به روش یک مطالعه‌ی مورد-شاهدی بود که بر روی 92 نمونه (دو گروه 46 تایی) از مایعات سروزی (آسیت و پلورال افیوژن) در بخش پاتولوژی بیمارستان الزهرا (س) به روش ELISA (Enzyme-linked immunosorbent assay) انجام گردید. نمونه‌های واجد شرایط به دو گروه شامل مایعات سروزی بدخیم (سیتولوژی مثبت) و مایعات سروزی خوش‌خیم (سیتولوژی منفی) دسته‌بندی شدند و سطح VEGF در دو گروه مورد آزمایش قرار گرفت. داده‌ها با استفاده از آزمون‌های Student-t و 2χ مورد آنالیز آماری قرار گرفتند.یافته‌ها: در گروه افیوژن بدخیم 22 مرد و 24 زن با میانگین سنی 57/14 ± 47/56 سال و در گروه افیوژن غیر بدخیم و واکنشی 30 مرد و 16 زن با میانگین سنی 07/17 ± 95/57 سال بودند. میانگین سطح VEGF در گروه افیوژن بدخیم 61/6 ± 71/753 و در گروه افیوژن واکنشی 99/143 ± 27/1 پیکوگرم در میلی‌لیتر بود. سطح VEGF در گروه دارای ترشحات سروزی بدخیم به طور معنی‌داری بالاتر بود )02/0 = P).نتیجه‌گیری: نتایج مطالعه‌ی حاضر نشان داد که می‌توان از VEGF به عنوان یک فاکتور بیوشیمیایی در شناسایی و افتراق مایعات سروزی بدخیم (سیتولوژی مثبت) از خوش‌خیم (سیتولوژی منفی) استفاده کرد.

چکیده [English]

Background: One of the factors effective on tumor cell growth and proliferation is vascular endothelial cell growth factor (VEGF). It also affects the formation of serous fluids such as ascites or pleural effusion through vascular permeability. However, detection and differentiation of malignant serous fluids from benign serous fluids have always been a problem. Therefore, the present study aimed to assess the diagnostic value and level of VEGF in differentiation of malignant serous fluids from benign serous fluids.Methods: This descriptive, analytical case-control study was conducted on 92 serous fluid (ascites and pleural effusion) samples from the pathology ward of Alzahra Hospital (Iran). The study employed enzyme-linked immunosorbent assay (ELISA) to evaluate samples. The samples were divided into 2 groups (n = 46 in each) of malignant serous fluids (positive cytology) and benign serous fluids (negative cytology). VEGF levels were examined in both groups. The data was analyzed using independent t-test and chi-square test.Findings: In the malignant effusion group, there were 22 males and 24 females with the mean age of 56.47 ± 14.57 years. In the benign effusion group, there were 30 males and 16 females with the mean age of 57.95 ± 17.07 years. The mean VEGF levels in the malignant effusion and benign effusion groups were 753.71 ± 6.61 and 143.99 ± 1.27 pg/ml, respectively. In addition, VEGF levels in the group with malignant serous discharge were significantly higher compared to the group with benign serous discharge (P = 0.02).Conclusion: The results of the present study showed that VEGF can be used as a biochemical factor in differentiation of malignant serous fluids (positive cytology) from benign serous fluids (negative cytology).
