Abstract

Background and Aims: Colorectal carcinoma is a gastrointestinal cancer&nbsp; that originates from colorectal polyps, particularly from adenomas, and it&nbsp; is the third most common cancer worldwide. The incidence and mortality&nbsp; rate of colorectal carcinoma markedly vary worldwide. These geographical&nbsp; differences may be related to dietary habits, environmental factors, and genetic&nbsp; susceptibility. In this study, the histomorphological features of colorectal&nbsp; polyps were evaluated in our region (Elazığ) and the risk stratification of&nbsp; adenomatous and nonadenomatous polyps was determined. Materials and&nbsp; Methods: Subjects who underwent colonoscopy during a 6-month period&nbsp; from June 2016 to December 2016 at the Gastroenterology Department of&nbsp; Firat University Hospital were retrospectively studied. Among 827 subjects,&nbsp; the data of 305 subjects who had colonic polyps were examined. Demographic&nbsp; features and colonoscopic and pathologic findings of the subjects&nbsp; were recorded. Polyp features including colonic distribution, localization,&nbsp; number, size, and histologic type were recorded. Polyps were divided into&nbsp; three subgroups based on their size as follows: <5 mm, between 5 and 10&nbsp; mm, and >10 mm. Polyps were further divided into three subgroups based&nbsp; on their number as follows: <5, from 5 to 10, and >10 polyps. The histological&nbsp; types of polyps were classified as nonadenomatous (hyperplastic) adenomatous&nbsp; and adenocarcinoma. Polyps with a high degree of dysplasia and/&nbsp; or invasive carcinoma, a size of >10 mm, and of the villous histological type&nbsp; were classified as advanced adenomas. Results: Among 827 subjects, 305&nbsp; (36.9%) had colonic polyps. Among these, 100 (32.8%) were females and&nbsp; 205 (67.2%) were males. Their mean age was 57.6 ± 13.6 years (min–max:&nbsp; 18–88). Based on the histological type, 115 subjects (37.7%) had nonadenomatous&nbsp; polyps, 173 (56.7%) had adenomatous polyps, and 17 (5.6%)&nbsp; had adenocarcinomas. Among the 173 subjects with adenomatous polyps,&nbsp; 106 (61.2%) had advanced adenomas. The polyps were pancolonic in 30&nbsp; subjects (9.8%) and located in the right colon in 71 subjects (23,3%) and in&nbsp; the left colon in 204 subjects (66.9%). Most of adenomas (64%) were located&nbsp; in the left colon. Among all polyps, 27.9%, 24.6%, and 2.3% were classified&nbsp; as tubular, tubulovillous, and villous adenomas, respectively. Conclusions:&nbsp; Male gender, advanced age, and increasing polyp number were found to be&nbsp; related to the development of advanced adenomas and adenocarcinomas.&nbsp; The close monitoring and follow-up of this group of patients are required.&nbsp; Prospective multicenter studies with a large number of patients are needed&nbsp; to determine the features of colonic polyps in Turkey.

Özet

Giriş ve Amaç: Önceden var olan kolorektal poliplerden, özellikle adenomlardan&nbsp; birkaç yıl sonra gelişen kolorektal karsinom gastrointestinal sistemin&nbsp; maligniteleri olup üçüncü en sık görülen kanserdir. Kolorektal karsinom&nbsp; insidans ve mortalitesi dünya çapında belirgin değişiklik göstermektedir. Bu&nbsp; coğrafi farklılık diyete, çevresel maruziyete ve genetik yatkınlığa bağlı gibi&nbsp; gözükmektedir. Bölgemizde kolorektal poliplerin histomorfolojik özelliklerinin&nbsp; değerlendirilmesi ve adenomatöz-nonadenomatöz poliplerin risk katmanlaşmasının&nbsp; belirlenmesi amaçlandı. Gereç ve Yöntem: Fırat Üniversitesi&nbsp; Tıp Fakültesi Gastroenteroloji Bilim Dalı’nda Haziran 2016-Aralık 2016 tarihleri&nbsp; arasında 6 aylık bir periyotta kolonoskopi işlemi uygulanan toplam&nbsp; 827 kişiden kolonik polip saptanan 305 hastanın verileri retrospektif olarak&nbsp; incelendi. Hastaların demografik verileri, patoloji ve kolonoskopi bulguları&nbsp; kaydedildi. Poliplerin özellikleri; kalın barsakta dağılımları, lokalizasyonu,&nbsp; büyüklükleri, sayısı, histolojik tipleri kaydedildi. Polip büyüklükleri <5 mm,&nbsp; 5-10 mm arası ve >10 mm olmak üzere 3 gruba ayrıldı. Polip sayıları 5’ten&nbsp; az, 5-10 arası ve 10’dan fazla olarak 3 sınıfa ayrıldı. Histoloji tipleri nonadenömatöz&nbsp; (hiperplastik), adenömatöz ve adenokarsinom olarak sınıflandırıldı.&nbsp; Yüksek derecede displazi ve / veya invaziv kanser bulunan, boyu 1 cm&nbsp; veya daha büyük adenomlar, villöz histoloji olanlar ileri adenom (advanced&nbsp; adenom) olarak sınıflandırıldı. Bulgular: Toplam 827 hastaya kolonoskopi&nbsp; yapılmış ve 305’inde (%36,9) polip saptanmıştı. Polip saptanan olguların&nbsp; 100’ü (%32,8) kadın, 205’i (%67,2) erkekti. Yaş ortalaması 57,6±13,6&nbsp; (min-max: 18-88) yıldı. Polip patolojik dağılımı 115’i (%37,7) hiperplastik,&nbsp; 173’ü (%56,7) adenomatöz, 17’si (%5,6) adenokarsinom olarak saptandı.&nbsp; Adenömatöz poliplerin 106’sı (%61,2) ileri adenom özellikteydi. Polipler&nbsp; hastaların 71’inde (%23,3) sağ kolon yerleşimli iken, 204’ünde (%66,9) sol&nbsp; kolon, 30’unda (%9,8) pankolonik yerleşimliydi. Adenomların çoğu (%64)&nbsp; sol kolon yerleşimliydi ve tüm poliplerin %27,9, %24,6 ve %2,3’ü sırasıyla&nbsp; tübüler, tübülovillöz, villöz adenomdu. Sonuç: Erkek cinsiyet, ileri yaş ve&nbsp; artan polip sayısı, ileri adenom ve adenokarsinom gelişimi ile ilişkili bulundu.&nbsp; Bu grup hastaların yakın takip ve izlemi gerekmektedir. Ülkemizde polip&nbsp; özelliklerinin belirlenmesi amaçlı, geniş katılımlı çok merkezli prospektif çalışmalara&nbsp; gereksinim vardır.
