Recurrent chromosome abnormalities in peripheral T-cell lymphomas.

Abstract
Cytogenetic findings in 45 cases of peripheral T-cell lymphomas (PTL) diagnosed according to the updated Kiel classification are reported. Recurrent numerical chromosome aberrations comprised -X, -Y, -13, +X, +3, +5 and +7. Recurrent structural aberrations included t/del(1)(p31-32), t(2;5)(p23;q35), dup(5)(q23q31-32), t/dup(6q), t/del(6q), trisomy 7q, and trisomy 8q, mostly due to i(8)(q10), and changes in 14q11 and 14q32.1, mostly due to inv(14)(q11q32.1), t/del(13)(q14), t(6;7)(q13;q13), and t(13;17)(q11-13;p11). All deletions in 6q involved band 6q21 and all partial trisomies of 7q led to an amplification of band 7q21. Further studies are needed to ascertain whether these cytogenetic findings in PTL are of clinical and prognostic significance.
