The authors analyzed only stage I patients with classical low-grade marginal zone lymphoma of the MALT type and detected the trisomy 3 using an alphasatellite DNA probe directed to the centromere. Their data support the observation that trisomy 3 is the most frequent cytogenetic aberration in MALT lymphomas .展开更多
