Value of PET/CT in diagnosis of lung cancer

Objectives: To remark on SUV of PET/CT in small-cell and non-small cell lung cancer and determine the value of PET/CT in the diagnosis of lung cancer. Subjects and methods: 58 patients diagnosed with lung cancer on PET/CT (24 patients with small cell and 34 patients with non-small cell in Oncology and Nuclear Medicine Center of Bachmai Hospital, from August 2010 to October 2015. | Journal of military pharmaco-medicine no8-2018 VALUE OF PET/CT IN DIAGNOSIS OF LUNG CANCER Bui Anh Thang1; Pham Ngoc Hoa1; Do Quyet2 SUMMARY Objectives: To remark on SUV of PET/CT in small-cell and non-small cell lung cancer and determine the value of PET/CT in the diagnosis of lung cancer. Subjects and methods: 58 patients diagnosed with lung cancer on PET/CT (24 patients with small cell and 34 patients with non-small cell in Oncology and Nuclear Medicine Center of Bachmai Hospital, from August 2010 to October 2015. Patients were performed with PET/CT to diagnose with lung cancer (size, metastasis) and compared with histopathological results. Results: 24 patients were diagnosed with small cell lung cancer, 33 patients were diagnosed with non-small cell lung cancer and 1 patient with benign lesion. The average of SUV was 5.91 ± 2.12. The average SUV was higher significantly in group of non-small cell than small cell lung cancer (6.58 ± 2.35 vs. 5.01 ± 1.35; p the activity of blood vessels in the mediastinum (2.5) can identify malignant lesions. - Comparisons of PET/CT results with histopathological findings: PET/CT (+): PET/CT images diagnosed with lung cancer. PET/CT (-): The PET/CT image is not diagnosed with lung cancer. Pathological anatomy results (+): surgery for lung cancer. Pathological anatomy results (-): anxiety is a benign lesion. - Data processing: According to the software SPSS 22.0. RESULTS 1. Age and gender. Table 1: Age and gender.
