Abstract

Background: In this study, we aimed to identify the sensitivity, specificity and diagnostic accuracy of integrated positron emission tomography- computed tomography (PET-CT) and endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the diagnosis of malignant mediastinal/hilar lymph nodes and to compare with each other. Methods: Records of 131 patients (96 males, 35 females; mean age 58.3±8.4 years; range 42 to 75 years) with known primary or suspected malignancy who had enlarged and hypermetabolic hilar/mediastinal lymph nodes detected by thoracic CT and at PET-CT and in whom EBUS-TBNA performed for cytologic confirmation of the malignancy between October 2008 and April 2011 were retrospectively analyzed. More invasive procedures including mediastinoscopy/video-assisted thoracoscopic surgery (VATS) were performed in patients who did not receive definite diagnosis using EBUS- TBNA. The maximum standardised uptake value (SUVmax) cut-off level of PET-CT was considered ≥3.0. The sensitivity, specificity, diagnostic accuracy, and negative and positive predictive values of PET-CT and EBUS-TBNA in diagnosis of malignant hilar/mediastinal lymph nodes were calculated. The results were compared with each other. Results: A total of 191 lymph node stations of 131 patients were aspirated from the LN stations. Of the 142 lymph nodes, 134 were diagnosed with malignancy using EBUS-TBNA, while SUV max value was ≥3.0 in 127 by PET-CT. The sensitivity, spesificity, diagnostic accuracy, and negative and positive predictive values of EBUS-TBNA and PET-CT were 94.3%, 100%, 95.8%, 85.9%, 100% and 89.4%, 18.3%, 71.2%, 37.5%, 76.0%, respectively. With combined use of EBUS-TBNA and PET-CT, the sensitivity increased to 100%. Conclusion: The sensitivity, specificity, diagnostic accuracy, and negative predictive value and positive predictive value of EBUS-TBNA is higher than PET-CT. Based on conventional data, histological confirmation of PET-CT is necessary in mediastinal staging, due to high level of false positivity of PET-CT. EBUS-TBNA is an effective, reliable and minimally invasive method for histologic confirmation of PET-CT-positive malignant mediastinal/hilar lymph nodes.

Özet

Amaç: Bu çalışmanın amacı, entegre pozitron emisyon tomografisi- bilgisayarlı tomografi (PET-BT) ve endobronşiyal ultrasonografi rehberliğinde yapılan transbronşiyal iğne aspirasyonunun (EBUS-TBİA) malign mediastinal/hiler lenf nodlarının tanısındaki duyarlılığı, özgüllüğü ve tanı değerini saptamak ve birbirleri ile kıyaslamaktır. Çalışma planı: Ekim 2008 - Nisan 2011 tarihleri arasında bilinen primer malignitesi veya malignite şüphesi olup, bilgisayarlı toraks tomografisinde büyümüş ve PET-BTde hipermetabolik hiler/mediastinal lenfnodu saptanan ve sitolojik tanı için EBUS-TBİA yapılmış 131 olgunun (96 erkek, 35 kadın; ort. yaş 58.3±8.4 yıl; dağılım 42-75) dosyası retrospektif olarak incelendi. EBUS-TBİA ile kesin tanı konulamayan olgulara mediastinoskopi/video yardımlı torakoskopik cerrahi (VYTC) gibi daha invazif girişimler uygulandı. PET-BTde malignite için standart maksimum alım (SUDmax) sınır değeri ≥3.0 olarak belirlendi. Malign mediastinal/hiler lenf nodlarının tanısında PET-BT ve EBUS-TBİAnın duyarlılık, özgüllük, tanı değeri ve negatif ve pozitif öngördürücü değerleri hesaplandı. Sonuçlar birbirleri ile karşılaştırıldı. Bulgular: Toplam 131 hastada 191 lenf nodu istasyonundan aspirasyon yapıldı. Yüz kırk iki malign lenf nodundan 134üne EBUS-TBİA ile malignite tanısı konulurken, 127sinin PET-BTde SUD max değerinin ≥3.0 olduğu görüldü. EBUS-TBİA ve PET-BTnin malign mediastinal ve hiler lenf nodlarının tanısındaki duyarlılık, özgüllük, tanı değeri ve negatif ve pozitif öngördürücü değerleri sırasıyla %94.3, %100, %95.8, %85.9, %100 ve %89.4, %18.3, %71.2, %37.5, %76.0 idi. EBUS-TBİA ve PET-BTnin birlikte kullanımı ile duyarlılık %100e ulaştı. Sonuç: EBUS-TBİAnın duyarlılık, özgüllük, tanı doğruluğu ve negatif öngördürücü değeri ve pozitif öngördürücü değeri PET-BTden daha yüksektir. Klasik bilgilere göre PET-BTnin yanlış pozitiflik oranının yüksek olması nedeni ile mediastinal evrelemede histolojik doğrulamasının yapılması gerekmektedir. EBUS-TBİA, PET-BT pozitif mediastinal/hiler lenf nodlarının histolojik doğrulamasında etkin, güvenilir ve minimal invasiv bir yöntemdir
