Hepatic arterial infusion of gemcitabine-oxaliplatin in a large metastasis from colon cancer

Figure 2 Computed tomography (CT) of liver metastasis. A: CT arteriography at baseline (A1), after 2 cycles (A2) and after 6 cycles (A3) of HAI. The metastasis was hypervascular at baseline. It became shorter after 2 cycles but remained as a stable disease according to RECIST. After 6 cycles, a partial response was observed (43% reduction in diameter); B: Dynamic contrast-enhanced CT (DCE-CT) scan at baseline (B1), after 2 cycles (B2) and after 6 cycles (B3). At baseline, the tumor was progressively and massively enhanced. After 2 cycles, there was a dramatic decrease in tumor perfusion, strongly suggesting the efficacy of HAI. Normal hepatic segment 4 is strongly enhanced. After 6 cycles, only small enhanced areas are visible within the residual tumor.
