Özet
Amaç: Kistik meme hastalıkları kadınlarda en fazla görülen meme hastalığıdır. Apokrin epitelli (Na/K<3) ve düz epitelli (Na/K>3) olmak üzere iki tip meme kisti bulunmaktadır. Yapılan çeşitli çalışmalar memesinde kistik bir oluşum bulunan kadınların 1.7-7.5 kat daha fazla meme kanserine yakalanma riski taşıdıklarını ortaya koymuştur. Kanserli hastaların periferal dolaşımına bakıldığında ise genellikle anormal bir amino asit profili saptanmıştır. Ayrıca, amino asit profilindeki değişiklikler organ düzeyindeki kanserler ile ilişkili bulunmuştur. Bu çalışmanın amacı meme kanseri gelişimi yönünden yüksek ve düşük risk grubu kistlerdeki amino asit düzeylerini incelemek ve bu kistlerden meme kanseri gelişimi yönündeki olası mekanizmaları araştırmaktır. Gereç ve Yöntemler: Çalışmada kistik meme hastalığı olan kadınlardan alınan meme kist sıvısı kullanıldı. Meme kist sıvısı amino asit düzeyleri HPLC metodu ile ölçüldü. Bulgular: Apokrin epitelli kist grubunda aspartik asit, glutamik asit, hidroksiprolin, serin, glisin, treonin, alanin, prolin, tirozin, metiyonin, izolösin, fenilalanin ve triptofan düzeyleri anlamlı olarak yüksek, lizin düzeyi ise düşük bulundu. Sonuç: Kanser gelişimi yönünden yüksek riske sahip olan apokrin epitelli kistlerde bulunan daha yüksek amino asit düzeyleri, amino asitlerin meme kanseri gelişim sürecinde potansiyel bir role sahip olabileceğini göstermektedir.
Objective: Gross cystic breast disease (GCBD) is the most common benign breast disease. There are two types of breast cyst; lined by apocrine epithelium (Na/K<3) or flattened epithelium (Na/K>3). Several studies have shown that women with palpable breast cysts may have 1.7-7.5 times higher risk of developing breast cancer. Patients with malignant disease usually show abnormal amino acid profiles in the peripheral circulation. Changes in amino acid profile diagnostically correlate with organ sites of malignancy. The aim of this study was to investigate the levels of amino acids in two cyst groups and possible mechanisms involved in the development of breast cancer. Material and Methods: The breast cyst fluid aspirated from women with GCBD were analysed. Breast cyst fluid amino acid levels were determined with HPLC. Results: Aspartic acid, glutamic acid, hydroxyproline, serine, glycine, threonine, alanine, proline, tyrosine, methionine, isoleucine, leucine, phenylalanine and tryptophan levels were significantly higher, and lysine levels were lower in the apocrine epithelial cysts. Conclusion: In this study, higher concentrations of amino acids in apocrine cysts, which are also known to have a higher risk of developing breast cancer, may indicate the possible role(s) of amino acids in the mechanism of breast cancer development.
