Abstract

Objective: Th oracentesis is the first investigation to be performed in a patient with lung cancer and pleural eff usion. Th e diagnostic yield of conventional smear studies varies in the first thoracentesis. In this study, we aimed to investigate if the cell block method increases the diagnostic yield in exudative pleural eff usions accompanying lung cancer. Material and Method: Forty patients with lung cancer and exudative pleural eff usions were included. Ten mililiters of fresh pleural fl uid was obtained by thoracentesis from all patients in the initial evaluation. Th e pleural fl uid sample was divided into two equal parts. One part was subjecte d to conventional smear and the other to the cell block method. Conventional smears were stained with May-Grünwald-Giemsa and Hematoxylin-Eosin. Cell block sections were stained with Hematoxylin-Eosin and mucicarmine. Conventional smear findings were grouped as “benign cytology” or “malignant cytology”. Th e cell block sections were evaluated for the presence of single tumor cells, acinary or papillary pattern, solid islands and staining with mucicarmine. Results: Th ere were 20 patients each in the benign and malignant conventional smear group. In the benign group, adding the cell block method to conventional smear pr ovided a diagnosis of malignancy in 4 more patients and the di agnosis of malignant eff usion was increased by a ratio of 10% (4/40). In the malignant group, adding the cell block technique provided the subtyping of lung cancer as adenocarcinoma in 7 patients (7/20, 35%). Conclusion: Our study confirms that the cell block method combined with conventional smear increases the diagnostic yield in exudative pleural eff usions accompanying lung cancer.

Özet

Amaç: Torasentez, plevra sıvısı olan akciğer kanserli bir hastada yapılması gereken ilk incelemedir. İlk torasentezde yapılan konvensiyonel sitolojik incelemelerin tanı başarısı değişkendir. Bu çalışmada, eksudatif plevra sıvısı olan akciğer kanserli hastalarda, hücre bloğu yönteminin tanıyı artırıp artırmağını araştırmayı amaçladık. Gereç ve Yöntem: Eksudatif plevral sıvısı olan 40 akciğer kanserli hasta çalışmaya alındı. Tanı aşa masında her hastadan torasentezle 10 ml plevra sıvısı alındı. Sıvı iki eşit parçaya ayrıldı. Bir kısım konvansiyonel sitoloji için kullanılırken diğer kısımdan hücre bloğu yapıldı. Konvansiyonel yaymalar May-Grünwald-Giemsa ve Hema- toksilen-Eosin ile boyandı. Hücre bloğu kesitleri Hematoksilen-Eosin ve musikarmin ile boyandı. Konvansiyonel sitoloji bulguları “benign sitoloji” ve “malign sitoloji” olarak gruplandı. Sitoblok kesitleri tek tümör hücresi, asiner, papiller patern, solid ada varlığı, musikarmin ile boyanma açısından değerlendirildi. Bulgular: Benign ve malign konvansiyonel sitoloji grubunun her birinde 20’şer hasta vardı. Benign konvansiyonel sitoloji grubunda, konvensiyonel sitolojiye ek olarak sitoloblok yapılması 4 hastaya daha malignite tanısı konmasını sağlayarak, malign sıvı tanısını (4/40) %10 oranında artırdı. Konvansiyonel sitolojisi malign olan grupta, sitoblok yönteminin beraber kullanılması, 7 hastada (7/20, %35) adenokarsinom tanısı koydurarak, akciğer kanserinin subtiplendirmesine olanak sağladı. Sonuç: Çalışmamız, akciğer kanserine eşlik eden eksudatif plevra sıvısı olan hastalarda, konvansiyonel sitoloji ile birlikte sitoblok yönteminin kullanılmasının tanı değerini artırdığını kanıtlamıştır.
