Abstract
Objective: Whole-body fluorodeoxyglucose-positron emission tomography (FDG-PET) has proved effective in the diagnosis of recurrent colorectal cancer (CRC) and in the monitoring of cancer therapy. However there have been limited studies considering the effect of FDG-PET in the initial evaluation of CRC. We analysed how FDG-PET affects the management of patients with CRC preoperatively. Material and Methods: A prospective study of 26 consecutive patients with known or suspected CRC was undertaken. The patients were evaluated by computed tomography (CT) and FDG-PET. FDG-PET results were compared with those of CT and correlated with histopathologic findings or with clinical course. Results: FDG-PET had a sensitivity of 96% and positive predictive value of 100% for the diagnosis of primary cancer, while CT had values of 68% and 95%, respectively. FDG-PET was superior to CT in detecting additional metastatic disease with a sensitivity of 89%, while CT had 33%. FDG-PET resulted in altered management for 8 patients of whom three avoided inappropriate surgery. Conclusion: It is concluded that FDG-PET is highly sensitive for the diagnosis and staging of patients with CRC. Its use in conjunction with CT results in a more accurate selection of patients for surgical treatment with curative intent. Amaç: Tüm vücut fluorodeoksiglukoz pozitron emisyon tomografi (FDGPET) görüntülemenin rekürren kolorektal kanser (KRK) tanısındaki ve kanser tedavisine yanıtın takibindeki rolü kanıtlanmıştır. Fakat KRK'in FDGPET ile preoperatif değerlendirilmesinin tedavi seçimine katkısı ile ilgili az sayıda çalışma mevcuttur. Bu çalışmada FDG-PET'in KRK'li hastalarda, preoperatif dönemde, hasta yönetimine katkısını araştırdık. Gereç ve Yöntemler: Bu prospektif çalışmaya, histopatolojik veya yüksek klinik şüphe ile KRK tanısı almış, 26 ardışık hasta (16 erkek, 10 kadın) dahil edildi. Tüm hastalar bilgisayarlı tomografi (BT) ve FDG-PET ile değerlendirildi. Histopatolojik veya klinik takip bulguları esas alınarak FDG-PET sonuçları BT sonuçları ile karşılaştırıldı. Bulgular: FDG-PET primer kanseri saptamada %96 duyarlılığa ve %100 pozitif öngörü değerine sahipken BT'de bu değerler sırasıyla %68 ve %95 idi. FDG-PET ilave metastatik hastalığı saptamada %89 duyarlılık ile BT'ye (%33) üstünlük göstermekteydi. FDG-PET 8 hastanın tedavi seçiminde değişikliğe neden olarak olumlu katkı yaptı, bunlardan 3'ünde gereksiz cerrahiden kaçınılmış oldu. Sonuç: FDG-PET'in KRK'in tanısında ve evrelemesinde yüksek duyarlılık gösterdiği sonucuna varılmıştır. BT ile birlikte kullanımı küratif amaçlı cerrahi işlem planlanan hastaların daha doğru şekilde seçilmelerine olanak sağlar.
