用于评价治疗效果修正的实体瘤疗效评价标准

Modified RECIST criteria used to evaluate treatment response

Response	CT mass size (RECIST)	CT mass quality	PET
Target lesions represent tumors treated with RFA. SUV: standard uptake value of fluorodeoxyglucose F¹⁸ in PET scan; LD: largest diameter of target lesions; FDG: fluorodeoxyglucose F¹⁸.

J Thorac Cardiovasc Surg, 2005, 129(3): 639-644.
Complete (any 2)	Lesion disappearance or scar < 25% original size	Cyst or cavity formation	SUV < 2. 5
Partial (any 1)	Decrease of > 30% in LD of target lesion	Low density of entire lesion Central necrosis or central cavitation with liquid density	Decreased SUV or area of FDG uptake
Stable lesion (any 1)	Decrease of < 30% in LD of target lesion	Mass solid appearance, no Central necrosis or cavity	Unchanged SUV or area of FDG uptake
Progression (any 2)	Increase of > 20% in LD of target lesion	Solid mass, invasion adjacent structures	Higher SUV
