Abstract

Objective: To investigate the diagnostic efficacy and accuracy of fine-needle aspiration biopsy (FNAB) in solid and cystic tumors of the major salivary glands, examine the histopathologic distribution and malignancy rates of non-diagnostic cases, and investigate any significant difference between benign and malignant salivary gland tumors according to age and tumor size Methods: Age, sex, tumor location, side, tumor size, preoperative diagnosis of FNAB, and final histopathological diagnosis of 182 patients with major salivary gland mass were retrospectively evaluated. Each lesion is categorized as solid and cystic. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and FNAB accuracy were separately calculated for parotid gland tumors, submandibular gland tumors, solid, and cystic tumors. Results: Among the 182 performed FNABs, 153 were benign, 9 were malignant, and 20 were non-diagnostic. Malignancy was detected in 12.2% of the parotid gland, 25.9% of the submandibular gland, and 14.2% overall. Unlike the parotid gland, when the FNAB of the submandibular gland was non-diagnostic, the final histopathology was most likely to be malignant than benign. No difference was found in the risk of malignancy between the solid and cystic tumors (p=0.192). The sensitivity, specificity, PPV, NPV, and accuracy of the major salivary gland FNAB in this study were 42.1%, 99.3%, 88.8%, 92.8%, and 92.5%, respectively. Conclusion: In the context of a non-diagnostic FNAB, high suspicion especially for the submandibular gland tumors is warranted for otorhinolaryngologists. Based on low sensitivity values, FNAB of the major salivary glands is limited as the only diagnostic tool.

Özet

Amaç: Majör tükrük bezlerinin solid ve kistik tümörlerinde ince iğne aspirasyon biyopsisinin (İİAB) tanısal etkinliğinin ve doğruluğunun araştırılması, non-diagnostik olguların histopatolojik dağılımının ve malignite oranlarının incelenmesi, yaş ve tümör boyutuna göre benign ve malign tükrük bezi tümörleri arasındaki farkın araştırılması amaçlanmıştır. Gereç ve Yöntem: Majör tükrük bezi kitlesi olan 182 hastanın yaşı, cinsiyeti, kitle lokalizasyonu, tarafı, kitlenin boyutu, preoperatif İİAB tanısı ve son histopatolojik tanısı retrospektif olarak değerlendirildi. Her bir lezyon solid ve kistik olarak kategorize edildi. Parotis bezi tümörleri, submandibuler bez tümörleri, solid ve kistik tümörler için duyarlılık, özgüllük, pozitif predediktif değeri (PPV), negatif prediktif değeri (NPV) ve doğruluğu ayrı ayrı hesaplandı. Bulgular: Gerçekleştirilen 182 İİAB’den 153’ü benign, 9’u malign ve 20’si non-diagnostik idi. Parotis bezi kitlelerinin %12,2’si, submandibuler bez kitlelerinin %25,9’u ve tüm majör tükrük bezi kitlelerinin ise %14,2’si maligndi. Parotis bezinden farklı olarak, submandibuler bezin İİAB’si non-diagnostik olduğunda, histopatolojik tanı büyük oranda (%80) maligndi. Solid ve kistik tümörler arasında malignite riski açısından fark yoktu (p=0,192). Bu çalışmada majör tükrük bezi İİAB’nin duyarlılığı, özgüllüğü, PPV, NPV ve doğruluğu sırasıyla %42,1, 99,3, 88,8, 92,8 ve %92,5 olarak bulundu. Sonuç: Özellikle submandibuler bez tümörleri için non-diagnostik bir İİAB varlığı, yüksek malignite şüphesi açısından kulak burun boğaz uzmanları için uyarıcı olabilir. Majör tükrük bezi tümörlerinde İİAB’nin düşük duyarlılık değerleri nedeniyle tek başına bir tanı aracı olarak kullanımı sınırlıdır.
