Trisomy 12 and t(14;22)(q32;q11) in a patient with B-cell chronic lymphocytic leukemia

Hematology. 2004 Oct-Dec;9(5-6):405-7. doi: 10.1080/10245330400018490.

Abstract

Recurrent cytogenetic abnormalities are typically found in about one third of B-cell chronic lymphocytic leukemia patients (B-CLL) by standard cytogenetic analysis and their prognostic relevance is well known. We report a case of a B-CLL patient showing both trisomy 12 and a t(14;22)(q32;q11). Trisomy 12 is often associated with aggressive disease and resistance to chemotherapy, however, our patient is in good health and currently untreated after 7 years, suggesting in this case a relatively good prognosis and a questionable role for translocations involving the 14q32 locus.
