SAMMSON and metastatic neoplasm: While SAMMSON expression in uveal melanoma tumors is independent from patient survival, tumor stage, primary tumor localization site (choroid, ciliary body or iris) and metastatic stage of the patient, SAMMSON expression is elevated in metastatic tumors compared to matched primary tumors (Fig. 1B, p = 0.022, Wilcoxon matched-pairs signed rank test, Supplemental Fig. 1).
