CD79A and ocular melanoma: Concerning the pre-IMRT IgA concentration analysis among different OM severity (grades 0,1,2, and 3), we divided OM severity during IMRT into two groups, i.e., grades 2 and 3 (n = 33) vs 0 and 1 (n = 7)when comparing the pre-IMRT IgA concentration from patients reaching grades 2 and 3 (mean: 10,36; SD ± 5,065) with those at grades 0 and 1 (mean: 17,72; SD ± 4,362) during IMRT and observed a significant difference (p = 0.0073).
