Patients presenting optimal morphologic responses during treatment with regorafenib. A, B. Optimal morphologic response observed at 175 days after initiation of regrafenib. Size of tumor was slightly increased (+ 6.0%) with reduction in CT density. CEA levels were 911 ng/ml (A) and 840 ng/ml (B), respectively. C, D. Optimal morphologic response observed at 105 days after initiation of regrafenib. Size of tumor was slightly increased (+ 16.0%) with evident change in CT texture of tumor. CEA levels were 860 ng/ml (C) and 910 ng/ml (D), respectively. E, F. Optimal morphologic response observed at 90 days after initiation of regrafenib. Although there was remarkable progression of tumor in number and size, serum CEA levels decreased from 91.7 ng/ml (E) to 66.1 ng/ml (F)
