Clinicopathological features of the nodal and extranodal groups. (A) Composite map showing clinicopathological features and loss of TCR loci in the N- and EN-groups. The map highlights lack of nasal involvement, CD8⁺/CD56⁻ phenotype, T-cell lineage and loss of TCR loci in the N-group compared to the EN-group. (B) Graph illustrating the association of CD8/CD56 phenotype with cell lineage. The CD8⁻/CD56⁺ phenotype is associated with NK-cell lineage while the CD8⁺/CD56⁻ phenotype is associated with T-cell origin. (C) Survival curve between the N- and EN-groups. Patients in the N-group had significantly shorter overall survival (OS) compared to those in the EN-group.
