Kaplan-Meier graph showing OS in splenic MZLs according to the presence of del(8p) only (P = .068), del(17p) only (P = .256), or del(8p) and del(17p) together (P = .004). Green represents patients bearing the lesion(s); and blue, patients without the lesion(s). x-axis represents time (months); and y-axis, percentage of patients alive.
