Objective response rate assessment in oncology: Current situation and future expectations

Table 7 The 5-point scale scores and Deauville criteria in Hodgkin Lymphoma[85-88]

Score	PET/CT scan result	At iPET	At end-of-treatment
1	No uptake	CMR	CMR
2	Uptake ≤ mediastinum	CMR	CMR
3	Liver ≥ Uptake > mediastinum	Inadequate response	Good prognosis
4	Uptake moderately higher than liver	PMR	Treatment failure
5	Uptake markedly higher than liver and/or new lesions	PMR	Treatment failure
X	New areas of uptake unlikely to be related to lymphoma

iPET: Interim positron emission tomography; CMR: Complete metabolic response; PMR: Partial metabolic response.
