Response	Target lesions	Non-target lesions	New lesions
CR	Disappearance of all target lesions	Disappearance of all non-target lesions	No
CR	Lymph node axis < 10mm	Normalisation of tumor marker levels	Partial response
PR	≥ 30% decrease in SLD from baseline (≥ 4 weeks)	No progression	No
PD	≥ 20% increase in SLD from Nadir with an absolute SoD increase ≥ 5mm	Unequivocal progression in lesion size	Yes, appearance of new unequivocally metastatic lesions
SD	Neither PR nor PD with the Nadir as reference point	Persistence of one or more non-target lesion and/or tumoral markers > normal	No
