Remark on suv of pet - ct in small cell lung cancer

SUMMARY

Objective: Determine the ability of PET/CT in detection of metastasis lesion in patient with small cell lung cancer and the correlation between FDG with size, stage of disease in patients with small cell lung cancer.

Subjects and methods: 24 patients were diagnosed of lung cancer by PET/CT and the histopathological finding was small cell lung cancer at Oncology and Nuclear Medicine Center of Bach Mai Hospital, from August 2010 to October 2015.

Results: PET/CT could detect the metastasis lesion at: mediastinal lymph nodes 54.2%, neck lymph nodes 37.5%, abdominal lymph nodes 12.5%, lung metastases 25%, bone 16.7%, liver and pancreas 4.2%. FDG uptakeis fairly wellcorrelated with tumor size (r = 0.446, p < 0.05). There is no correlation between FDG uptake with the stage of cancer. Conclusion: PET/CT plays an important role in diagnosis of small cel lung cancer.

Keywords: PET / CT, small cell lung cancer.
