We analyzed timeliness of care and the diagnostic performance of FDG-PET/CT to differentiate between malignant and benign lesions.RESULTSIn 386 patients available for analysis, 260 patients were diagnosed with non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC) of both subtypes; 23 patients had another type of malignancy, 78 patients had certain benign disease, and in 45 patients the diagnosis was not pathologically confirmed but a median 24.5 months follow up confirmed a benign outcome. Sensitivity, specificity, negative predictive value, positive predictive value and accuracy of FDG-PET/CT to differentiate lung cancer from benign disease were 97.7%, 60.2%, 92.5%, 84.0% and 85.7% respectively. For lung cancer patients, median referral time was seven days, diagnostic delay was 2 days and therapeutic delay 19 days.CONCLUSIONFDG-PET/CT in an RODP setting for suspected lung cancer has high performance in detecting cancer and facilitates timely care.
