The association between PFS and change ratios of SUVmax and the tumor diameter sum after 1 month in individual patients. The information about PFS (days) was added as height to the 2-dimensional graph demonstrating the change ratios of SUVmax (horizontal axis) and those of tumor diameters sum (vertical axis) after 1 month in individual patients. Blue bars show the PFSs of good responders (diameter sum does not increase and SUVmax decreases ≥ 20%), yellow bars indicate those of intermediate responders (diameter sum does not increase and SUVmax decreases<20%), and red bars indicate those of poor responders (diameter sum increases or new lesions appear).
