چکیده

مقدمه
سرطان معده (GC)، یکی از سرطان‎های شایع دستگاه گوارش می‎باشد که به  یک مشکل عمده بهداشتی در سراسر جهان مبدل شده است. در طی سالیان اخیر محققان مختلفی ویروس ها را در پاتوژنز سرطان دخیل نشان داده‎اند. لذا هدف از این مطالعه، بررسی فراوانی حضور شناسایی سیتومگالوویروس(CMV) در سرطان معده با روش ایمنوهیستوشیمی‎و PCR در بیمارستان‎های ‎سطح استان آذربایجان شرقی می‎باشد. 
روش کار
در این مطالعه توصیفی-مقطعی، 50  نمونه بافتی سرطان معده از بلوکه‎های ‎پارافینی بیمارستانهای سطح استان آذربایجان شرقی همراه با 50  نمونه غیر بدخیم (زخم معده) و 50  نمونه کنترل انتخاب شدند.  حضور عفونت ویروسی CMV  با روش ایمونوهیستوشیمی‎و  PCR انجام شد. جهت تجزیه و تحلیل داده ها از نرم افزار SPSS نسخه 19 و آزمون کای اسکوئر استفاده شد.
نتایج
در نمونه‎های ‎بدخیم مورد مطالعه، 3  نمونه (6 %) با روش ایمونوهیستوشیمی‎حاوی پروتئین pp65 و 5 نمونه (10 %) حاوی DNA CMV بودند. ولی هیچ پروتئین و DNA ویروسی در نمونه‎های ‎غیربدخیم و کنترل مشاهده نشد. نمونه‎های ‎IHC وDNA CMVمثبت به ترتیب دارای میانگین سنی 43/14 ± 33/58 و50/12 ± 4/59 بودند. آزمون کای اسکوئر ارتباط معنیداری بین نمونه‎های ‎IHC وDNA CMVمثبت نشان نداد.
نتیجه گیری
در استان آذربایجان شرقی میزان حضور سایتومگالوویروس شیوع پایینی داشته و بیشتر در رده سنی بالای 50 سال و بیشتر در آقایان دیده می‎شود. باتوجه به اینکه حضور CMV با نتایج IHC و DNA CMV مثبت یکسان نبوده بنابراین  در این مطالعه روش PCR دقت بالا و کارآمدی بیشتری داشته است.

چکیده [English]

Background and Aim: Gastric cancer (GC) is one of the most common gastrointestinal cancers that has become a major health problem worldwide. In recent years, various researchers have shown viruses to be involved in the pathogenesis of cancer. Therefore, the aim of this study was to evaluate the frequency of the presence of cytomegalovirus (CMV) in GC by immunohistochemistry (IHC) and PCR .
Methods: In this descriptive cross-sectional study, 50 GC tissue samples were selected from paraffin blocks of hospitals in East Azerbaijan province along with 50 non-malignant samples (gastric ulcer) and 50 control samples. The presence of CMV viral infection was determined by IHC and PCR. SPSS software and Chi-square test were used to analyze the data.
Results: In the malignant samples studied, 3 samples (6%) were immunohistochemically containing pp65 protein and 5 (10%) samples contained CMV DNA. But no viral protein and DNA were observed in non-malignant and control samples. IHC and CMV positive DNA samples had a mean age of 58.33 ±14.43 and 59.40 ± 12.50, respectively. Chi-square test did not show a significant relationship between IHC and CMV DNA samples.
Conclusion: In East Azerbaijan province, the presence of CMV is low and is more common in men over 50 years and older Considering that the presence of CMV was not the same as the results of IHC and positive CMV DNA, therefore, in this study, the PCR method was more accurate and efficient.
