Abstract

Review on t(5;17)(p11;q11) and t(5;17)(q11-12;q11-12), with data on clinics.

Clinics and Pathology

Disease

Acute myeloid leukemia (AML)

Epidemiology

Described in 2 male and 3 female patients aged 28 to 70 years; Acute myeloblastic leukemia with maturation (FAB type M2) in 3 (Huebner et al., 2000; Paietta et al., 1988; Arnaud et al., 2005) and AML-NOS in 2 patients (Suciu et al., 1993; Kerndrup and Kjeldsen., 2001) (Table 1).

Prognosis

May represent an unfavorable cytogenetic prognostic category in association with monosomy 7 and/or complex karyotypes.

Cytogenetics

Cytogenetics morphological

Presents as 1 normal chromosome 5 and 17, a der(5) chromosome containing the short arms of chromosomes 5 and 17, and a der(17) chromosome containing the long arms of both chromosomes; breakpoints at or near the centromeres may be uncertain; the most common described translocation was t(5;17)(q11;q11) reported in 3 out of 5 patients. Fluorescence in situ hybridization with centromere-specific probes for chromosomes 5 and 17 allows precise breakpoint definition and confirm the presence of a chromosome centromere and/or the unbalanced dic(5;17) rearrangement.

Additional anomalies

Complex chromosome rearrangements in all the 5 described patients, found in association with monosomy 7 in 2 (Huebner et al., 2000; Arnaud et al., 2005) and trisomy 8 in 3 patients (Paietta et al., 1988; Suciu et al., 1993; Kerndrup and Kjeldsen., 2001).

Result of the Chromosomal Anomaly

Oncogenesis

The reciprocal, apparently balanced t(5;17)(p11-q11;q11) is a rare but non-random anomaly in acute myeloid leukemia, that may be particularly associated with acute myeloblastic leukemia with maturation (AML-M2). The key mechanism of oncogenesis is unknown; however as it presents in association with known anomalies such as monosomy 7 or trisomy 8 in all the described cases, it is likely that it represents a secondary anomaly that developed during the multistep process of leukemogenesis.
