Kolon Adenomlarında Paneth Hücresi Görülme Sıklığı

Year 2016, Volume: 8 Issue: 1, 27 - 30, 01.03.2016

Abstract

Amaç: Kolon adenomlarında Paneth hücre görülme sıklığını ve klinikopatolojik özelliklerle ilişkisini ortaya koymaktır. Gereç ve Yöntem: Ocak 2013-Eylül 2014 arasında bölümümüzde kolon adenomu tanısı alan 203 hastadan basit rastgele örnekleme yöntemi ile seçilmiş 65 hastaya ait 98 adet adenoma olgusunda Paneth hücresi varlığı ışık mikroskobunda değerlendirildi. Cinsiyet ve yaşa göre dağılım sıklığı araştırıldı. Paneth hücresi içeren adenomlarla içermeyenler arasında lokalizasyon, villöz morfoloji, adenoma sayısı karşılaştırıldı. Bulgular: Adenomu olan 65 hastanın kadın/erkek oranı 21/44, yaş ortalaması [62,03 SD=12 ] idi. Altı hastada üç, 21 hastada iki, 38 hastada bir adet olmak üzere toplam 98 adet adenoma incelendi. Adenomlar en sık sigmoid kolonda %24,5 24/98 ve rektumda %15,3 15/98 izlendi. Adenomların %33,7 33/98 sinde Paneth hücre varlığı saptandı. Erkeklerde Paneth hücresi gösteren adenom oranı %40,3 kadınlarda Paneth hücresi gösteren adenoma oranından %15,4 3,7 kat yüksek bulundu %95 GA=1,2-11,9, p=0,029* . Proksimal kolonda Paneth hücresi gösteren adenoma olasılığı %51,2 , distal kolonda Paneth hücresi içeren adenoma olasılığından %20 4,2 kat yüksek bulundu %95 GA=1,7-10,2, p=0,001 . Tek adenomlu olguların %31,6’sında Paneth hücresi varken, bu oran iki ve üzeri adenomu olan olgularda en az birinde %55,6 olarak hesaplanmıştır p=0,053 . Paneth hücresi gösteren adenomların %3,1 3/98 ‘inde villöz morfoloji izlendi.Sonuç: Çalışmamızda, kolon kanserlerinde premalign lezyon olarak kabul edilen kolon adenomlarının yaklaşık üçte birinde Paneth hücresi saptanmıştır. Paneth hücresi gösteren adenomların erkeklerde ve proksimal kolonda istatiksel olarak anlamlı düzeyde yüksek olduğu gözlenmiştir. Bulgularımız literatürle uyumludur. Bununla birlikte daha geniş serilerde araştırma yapmaya gereksinim olduğu düşünüldü

The Incidence of Paneth Cells In Colon Adenomas

Year 2016, Volume: 8 Issue: 1, 27 - 30, 01.03.2016

Abstract

Aim:The aim of the study was to determine the incidence of Paneth cells and its relationship with the clinicopathologic characteristics in colon adenomas.Materials and Methods: The presence of Paneth cells were evaluated with light microscope in 98 adenoma cases from 65 randomly chosen patients out of 203 that were diagnosed with colon adenoma between January 2013 and September 2014. The frequency of Paneth cells were investigated according to gender and age. Paneth cell-containing and non-Paneth cell-containing adenomas were compared with each other for the location, villous morphology and the number of adenomas.Results: The male/female ratio of the 65 patient with tubular adenoma diagnosis was 21/44 and the mean age was [62.03 SD=12 ]. A total of 98 adenomas 6 patients with three adenomas, 21 patients with two adenomas and 38 patients with one adenoma were examined. Paneth cell presence was determined from 33.7% 33/98 of the adenomas. Adenomas were mostly seen in sigmoid colon 24.5% 24/98 and rectum 15.3% 15/98 . The percentage of the Paneth cell-containing adenoma in male 40.3% was 3.7% higher than females 15.4% %95 CI=1.2-11.9, p=0.029* . The probability of Paneth cell-containing adenoma 51.2% in proximal colon was 4.19 times higher than distal colon 20% 95% GA=1.7-10.2, p=0.001 . Paneth cells presence was seen 31.6% in cases with one adenomas while this ratio was determined as 55.6% in cases with two adenomas at least in one p=0,053 . Villous morphology was seen 3.1% 3/98 of the Paneth cell-containing adenomas.Conclusion: Paneth cells were determined from one third of the tubular adenomas that were considered as premalignant lesions of colon cancers in the study. Paneth-cell-containing adenomas were found statistically significant in males and proximal colon. Our findings are concordant with the literature. However, the need of investigations with larger series is considered
