Bisig et al. [9] compared the expression profiles of 16 PTCL, NOS [six CD30(+) and ten CD30(−)] and 35 ALCL [25 ALK(+) and 10 ALK(−)] in their study of CD30(+) peripheral T-cell lymphomas and showed that their molecular findings further corroborated the biological continuum across CD30(+) PTCL. Here, ALK is linked to peripheral T-cell lymphoma, not otherwise specified.
