AKCİĞER LEZYONLARINDA POZİTRON EMİSYON TOMOGRAFİSİ

Year 2008, Volume: 22 Issue: 1, 7 - 12, 01.05.2008

Abstract

Pozitron emisyon tomografi (PET) metabolik ve anatomik bilgiler veren yeni bir görüntüleme şeklidir. Bu çalışmada, kliniğimizde opere olan hastalarda preoperatif PET bulguları ile postoperatif histopatolojik sonuçların uyumu değerlendirilmiştir. Mayıs 2006 ile Ocak 2007 tarihleri arasında preoperatif dönemde PET tetkiki yapılan ve cerrahi girişim uygulanan 20 hasta çalışmaya alındı. PET ve operasyon bulguları karşılaştırılarak PET için doğru pozitif (DP), doğru negatif (DN), yalancı pozitif (YP), yalancı negatif (YN) değerleri saptandı ve duyarlılık, özgüllük, pozitif tahmini indeks (PTI), negatif tahmini indeks (NTI) ve doğruluk oranları hesaplandı. Hastaların 16' sı erkek dördü kadın, yaş ortalaması 51.9 idi. PET ile incelenen 20 hastada primer kitle ve lenf nodu dahil olmak üzere toplam 35 lezyon değerlendirildi. Buna göre preoperatif tetkikleri ve taramaları tamamlanan hastalar operasyona alındı. Hastalara uygun olan invazif cerrahi girişim uygulandı. Malign hastalarda rezektif girişimlere ek olarak mediastinal lenf bezi disseksiyonu uygulandı. PET' deki lezyonlar postoperatif histopatolojik sonuçlarla karşılaştırıldığında 14 DP (%40), 14 DN (%40), 3 YP (%8.6), 4 YN (%11.4) sonuçla karşılaşıldı. PET için duyarlık %78, öz güllük % 82, PTI % 82, NTI %78 ve doğruluk oranı %80 olarak hesaplandı. Sonuç olarak, çalışmamızda PET-BT ile elde edilen doğruluk oranlarının malign ve benign ayırımında, kanser evrelemesinde ve tedaviye olan cevabın değerlendirilmesinde yeterli olduğu, saptanan PTI ve NTI oranlarının anlamlı olmakla birlikte invazif tanı yöntemleri ile desteklenmesi gerektiği izlenmiştir. PTI nin seçilmiş hasta gruplarında daha yüksek bulunabileceği, bununda invazif girişimle doğrulama endikasyonlarını genişletebileceği kanaatindeyiz.

POSITRON EMISSION TOMOGRAPHY IN LUNG LESIONS

Year 2008, Volume: 22 Issue: 1, 7 - 12, 01.05.2008

Abstract

Positron emission tomography (PET) is a new imaging modality offering anatomic and metabolic information and it is being used to differentiate benign from malignant lesions. The aim of this study is to evaluate the result of the PET analysis in the patients who were performed surgery after PET examination. The patients who were examinated with PET and were performed surgery in preoperative period were included in the study between May 2006 to January 2007. The value of true positive (TP), true negative (TN), false pozitive (FP), false negative (FN) for PET were found by compairing with PET and surgery findings. The ratio of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy were calculated. 20 patients were included in the study. 16 of them were male. Mean age was 51,9. Wedge resection, lobectomy, pneumonectomy, mediastinoscopy, cystotomy - capitonage, and medistinal lymph node dissection were performed. 35 lesions including primary mass and lymph nodes were evaluated in 20 patients. Fourteen lesion were TP, 14 lesions were TN, 3 lesions were FP, 4 lesions were FN in PET results. According to these results it was found for PET that sensitivity was 78%, specificity was 82%, PPV was 82%, NPV was 78% and accuracy was 80%. Conclusion, despite high reliability of PET which plays an important role for the distinction of malign and benign lesions, staging of cancer and for the evaluation of its response to treatment, it should be taken into consideration that it could give deceiving results.
