The volumetric change in the choroidal melanoma of each patient. Solid lines show the volumetric changes in recurrent tumors. (A) Absolute changes in tumor volume. Thick solid lines show the changes in the mean volume 12 months after proton beam therapy. (B) The relative changes in tumor volume. The thick solid line shows the regression of the relative volume. The thick and short-dashed lines represent the regression lines of patients with large tumors. The thick and long-dashed lines represent the regression lines of patients with small tumors.
