بررسي توزيع فراواني و توزيع سني انواع كيست هاي نئوپلاستيك و غير نئوپلاستيك تخمدان در نمونه هاي سيستكتومي

The Frequency and Type of Neoplastic and Nonneoplastic Ovarian Cysts in Cystectomy Specimens

كيست هاي تخمدان از جمله شايع ترين وضعيت هاي پاتولوژيك تخمدان هستند. اين مطالعه با هدف تعيين توزيع فراواني و توزيع سني انواع كيست هاي غير نئوپلاستيك و نئوپلاستيك تخمدان در نمونه هاي سيستكتومي تخمدان انجام شد. روش ها: در اين مطالعه ي مقطعي، جامعه ي آماري مورد مطالعه شامل زنان مبتلا به كيست تخمدان بود كه از سال 1386 تا 1388 در بيمارستان بهشتي اصفهان تحت عمل جراحي سيستكتومي قرار گرفتند. تعداد نمونه، 200 عدد و روش نمونه گيري سرشماري بود. بيماران بر اساس سن در يكي از سه گروه پيش از بلوغ، سنين باروري و سنين پس از منوپوز قرار گرفتند. كيست هاي تخمدان به دو گروه غير نئوپلاستيك و نئوپلاستيك تقسيم شدند. اطلاعات از گزارش پاتولوژي و پرونده ي بيماران جمع آوري و وارد فرم جمع آوري اطلاعات گرديد و با استفاده از نرم افزار SPSS تحت آناليز آماري قرار گرفت. نتيجه گيري: بر اساس نتايج اين مطالعه كيست هاي غيرنئوپلاستيك تخمدان فراوان تر از كيست هاي نئوپلاستيك بود و اندومتريوز شايع ترين نوع كيست تخمدان بود. اكثريت كيست هاي تخمدان در سنين باروري مشاهده شد.

Background: Ovarian cysts are among the most frequent pathologic states of the ovary. The goal of this study was to determine the frequency and age distribution of various types of ovarian cysts. Methods: In this cross-sectional investigation, 200 women with ovarian cyst who had undergone ovrian cystectomy in Shahid Beheshti hospital in Isfahan between years 2007-2009 entered the study. Three age groups including prepuberty, reproductive, and postmenopausal were considered. The cysts were categorized as nonneoplastic or neoplastic. Data were extracted from pathology reports and patients’ records. SPSS software was used for data analysis. Finding: Mean age of the patients was 31.4 ± 9.8 years. 1.5%, 92% and 6.5% of the patients were in prepuberty, reproductive, and postmenopausal age groups, respectively. 42% of the cysts were neoplastic and 58% were nonneoplastic. No statically significant relationship was observed between the nature of the cyst and age group. Overall, endometriosis with frequency of 18% was the most frequent cyst. Among neoplastic cysts, serous cystadenoma and dermoid cyst, each with frequency of 31.2% were the most common types. There wasn’t any significant relationship between the mean ages of various neoplastic cysts. Endometriosis with the frequency of 31% was the most common nonneoplatic cyst and there wasn’t any significant relationship between the age group and the type of nonneoplastic cyst . Conclusion: The majority of ovarian cysts are nonneoplastic and endometriosis is the most frequent type of ovarian cysts in surgically removed specimens. Most of the ovarian cysts are observed in reproductive age.
