简要总结
The purpose of this study is to evaluate whether a semi-quantitative interpretation using the liver SUVmax as reference can better interpret 18F- FDG PET/CT and predict disease progression during chemotherapy or survival in NK/T-cell lymphoma.
详细描述
In this study investigators develope a semi-quantitative interpretation using the liver SUVmax as reference to interpret 18F-FDG PET/CT. Positive lesions in PET were indicated as SUVmax of residues higher than the threshold or new 18F-FDG avid lesions. Investigators compare the prognostic accuracy of the liver SUVmax-based criteria with the 5-PS criteria and ΔSUVmax interpretation with respect to predicting disease progression during chemotherapy or survival in NK/T-cell lymphoma. Furthermore,investigators improve the prognostic ability of interim PET/CT by comparing the results to the clinical prognostic factors.
