The Genetic Deletion of 6q21 and PRDM1 and Clinical Implications in Extranodal NK/T Cell Lymphoma, Nasal Type

Figure 4

Kaplan-Meier survival analysis of PRDM1 immunostaining, 6q21 deletion, and PRDM1 deletion in follow-up cohort of 40 EN-NK/T-NT cases. PRDM1 positive immunostaining predicted a favorable effect on overall survival (OS) (a, ) and failure-free survival (FFS) (b, ) of EN-NK/T-NT patients. However, the status of 6q21 (c, d) and specific PRDM1 gene alone (e, f) showed no significant correlation with the OS and FFS as those of the deletion of 6q21 and/or specific PRDM1 gene (g, ; h, ).
