A AB BS ST TR RA AC CT T O Ob bj je ec ct ti iv ve e: : Non-melanoma skin cancers (NMSC) represent the most frequent cancers among the Caucasian population worldwide. The possibility of the involvement of human papillomavirus (HPV) in the development of these cancers is suggested by several studies. The purpose of this study is to evaluate the presence of various types of HPV in NMSC lesions of immunocompetent patients. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : Biopsies taken from NMSC and non-sun exposed healthy skin from each of 32 immunocompetent patients were analysed for presence of HPV DNA by a polymerase chain reaction (PCR) using degenerate primers which can detect a broad spectrum of HPV types. R Re es su ul lt ts s: : HPV DNA was detected in one of 21 basal cell carcinomas, from one of two actinic keratosis and from none of 8 squamous cell carcinomas, and none of the control biopsy specimens. It was thought that in addition to factors associated with Turkish population, the specimens which were found to be HPV negative did not harbor HPV DNA, or although tissues harbor HPV DNA, it was not detected with the technique we used because of low viral load. C Co on nc cl lu us si io on n: : We could not show an association between HPV infection and NMSC by using real-time PCR technique. Our data suggest that the use of MY09/MY11 primer pairs alone in PCR technique is not sufficient to evaluate the HPV prevalence in NMSC. We thought that studies with more patients and using more sensitive detection techniques which will be developed in the future are needed to show a significant association between HPV and NMSC development.K Ke ey y W Wo or rd ds s: : Skin neoplasms; betapapillomavirus; polymerase chain reaction Ö ÖZ ZE ET T A Am ma aç ç: : Melanom dışı deri kanserleri (MDDK) dünya çapında beyaz ırkta en sık görülen kanserlerdir. Human papillomavirüslerin (HPV) bu kanserlerin gelişimine katkıda bulunuyor olabileceği birçok çalışmada öne sürülmüştür. Bu çalışmanın amacı, bağışıklık sistemi normal hastalardaki MDDK lezyonlarında farklı HPV tiplerinin mevcudiyetini değerlendirmektir. G Ge er re eç ç v ve e Y Yö ön nt te em ml le er r: : Bağışıklık sistemi normal 32 hastanın her birinin MDDK ve güneş görmeyen sağlıklı derilerinden alınan biyopsiler, HPV tiplerinin geniş bir spektrumunu saptayabilen dejenere primerlerin kullanıldığı polimeraz zincir reaksiyonu (PZR) ile incelendi. B Bu ul lg gu ul la ar r: : HPV DNA, 21 bazal hücreli karsinomun 1 tanesi ve 2 aktinik keratozun 1 tanesinde saptanırken, 8 yassı hücreli karsinom ve kontrol deri örneklerinin hiçbirinde HPV DNA saptanmadı. Bu durumun, Türk toplumuyla ilişkili faktörlere ek olarak, HPV negatif olarak bulunan numunelerin HPV DNA içermemesine veya bu dokular HPV DNA içeriyor olmasına rağmen, viral yükün düşük olması nedeniyle bizim kullandığımız yöntemle saptanamamış olmasına bağlı olabileceği düşünüldü. S So on nu uç ç: : Biz çalışmamızda real-time PZR tekniği kullanarak MDDK ve HPV enfeksiyonu arasında ilişki gösteremedik. MDDK'de HPV pr...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
