Şimdiye kadar bir grup protoonkogen ve tümör supressör gen üzerinde meydana gelen değişikliklerin kanser oluşumunda etkili olduğu ortaya konmuştur. Tümör supressör gen grubundan olan ve kanser oluşumunda etkili olan genlerin başında p53 gelmektedir. p53 meme kanserinin gelişiminde oldukça etkili olduğu bilinmektedir, bu nedenle p53 gen mutasyonlarının tespitinin hastalığın takibinde ve erken tanısında önemli bir faktör olabileceği düşünülmektedir. Bu çalışmada, meme kanserlerinde p53 genindeki ekson 5 ve 7’ye ait mutasyonların görülme sıklığı ve immunohistokimyasal yöntem ile p53 proteininin varlığının tespitini amaçladık. Buna bağlı olarak meme kanseri tanısı konmuş 20 olguya ait tümör dokusundan izole edilen DNA örneklerinden PCR tekniği kullanılarak ekson 5 ve 7 amplifiye edildi ve enzim kesimi ile mutasyon varlığı araştırıldı. Çalışma sonunda 20 olguya ait p53 genindeki ekson 5 ve 7’ye ait mutasyon oranı toplam %30 olarak bulundu. Ekson 5’e ait mutasyon oranı %20 ve ekson 7’ye ait mutasyon oranı %11,8 olarak saptandı. Aynı örneklere immunohistokimyasal yöntem ile p53 antikoru uygulandı. Boyanma sonrasında 4 olguya ait örnekte %90 ve üzeri, 1 olguda %3, 2 olguda %1 ve 2 olguda %0,5 p53 protein pozitifliğinin varlığı tespit edildi. Olguların 11 tanesinde p53 protein varlığı gözlenmedi</p></abstract>
