Abstract

Objective: Fine needle aspiration cytology is the first step in the diagnosing breast lesions. This study evaluated factors causing falsenegative and false-positive diagnoses when evaluating breast lesions using this technique.Material and Method: In this study, we retrospectively examined 511 breast diagnoses, based on Fine needle aspiration cytology specimens, made in the Medical School of Zonguldak Karaelmas University, Department of Pathology, between 2002 and 2009. Factors affecting the reliability of fine needle aspiration cytology were evaluated by comparing the cytological and biopsy diagnoses and using the clinical parameters in the diagnosis of breast lesions.Result: In our series, the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of fine needle aspiration cytology were 77%, 99%, 95%, 93%, and 95%, respectively. The falsenegative diagnosis rate was 4% and the false-positive diagnosis rate was 1%.Conclusion: Sampling errors and erroneous interpretation of cellular monomorphism are the most important reasons for false-negative diagnosis results in the evaluation of breast lesions with fine needle aspiration cytology. Increased cellularity and reactive cell atypia in benign proliferative breast lesions are the most frequent reasons for false-positive diagnosis.

Özet

Amaç: İnce iğne aspirasyon sitolojisi, meme lezyonlarında yaygın olarak kullanılan ilk aşama tanı yöntemidir. Bu çalışmada, meme lezyonlarının bu teknik ile değerlendirilmesinde yanlış negatif ve yanlış pozitif tanılara neden olan etkenler araştırılmıştır.Gereç ve Yöntem: Zonguldak Karaelmas Üniversitesi Tıp Fakültesi Patoloji Anabilim Dalı'nda 2002–2009 yılları arasında tanı alan 511 meme ince iğne aspirasyon sitolojisi materyali retrospektif olarak gözden geçirilmiştir. Sitopatolojik tanılar, olgulara ait biyopsi tanıları ve klinik takip sonuçları eşliğinde değerlendirilerek, meme lezyonlarının tanısında ince iğne aspirasyon sitolojisi'nin güvenilirliğine etki eden faktörler irdelenmiştir.Bulgular: Serimizde meme lezyonlarında ince iğne aspirasyon sitolojisi'nin duyarlılığı %77, özgüllüğü %99, doğruluğu %95, pozitif öngörü değeri %93, negatif öngörü değeri ise %95 olarak belirlenmiştir. Yanlış negatif tanı oranımız %4, yanlış pozitif tanı oranımız ise %1'dir.Sonuç: Meme lezyonlarının ince iğne aspirasyon sitolojisi ile değerlendirilmesinde hücresel monomorfizmin yanlış yorumlanması en önemli yanlış negatif tanı nedenidir. Benign proliferatif meme lezyonlarındaki artmış selülarite ve reaktif hücresel atipi ise en sık yanlış pozitif tanı nedenlerini oluşturmaktadır.
