PURPOSE: Recent metaphase cytogenetic studies suggested that specific chromosomal abnormalities are of prognostic significance in patients with multiple myeloma (MM). Because the true incidence of chromosomal abnormalities in MM is much higher than that detected by metaphase analysis, we used interphase fluorescence in situ hybridization (FISH) to determine the prognostic value of specific chromosomal aberrations. PATIENTS AND METHODS: Bone marrow plasma cells from 89 previously untreated patients with MM were studied consecutively by FISH to detect the deletions of 13q14, 17p13, and 11q and the presence of t(11;14)(q13;q32). FISH results were analyzed in the context of clinical parameters (response to treatment and survival after conventional-dose chemotherapy), and a multivariate analysis of prognostic factors was performed. RESULTS: By FISH, the deletion of 13q14 occurred in 40 patients (44.9%), deletion of 17p13 in 22 (24.7%), and 11q abnormalities in 14 (15.7%; seven with t(11;14)). Deletions of 13q14 and 17p13 were associated with poor response to induction treatment (46.9% v 77.3% in those without deletions, P = .006 and 40.0% v 73.2%, P = .008, respectively) and short median overall survival (OS) time (24.2 v 88.1 months, P = .008 and 16.2 v 51.3 months, P = .008, respectively). Short median OS time was also observed for patients with 11q abnormalities (13.1 v 41.6 months, P = .02). According to the number of unfavorable cytogenetic features (deletion of 13q14, deletion of 17p13, and aberrations of 11q) that were present in each patient (0 v 1 v 2 or 3), patients with significantly different OS times could be discriminated from one another (102.4 v 29.6 v 13.9 months, P < .001, respectively). CONCLUSION: For patients with MM who were treated with conventional-dose chemotherapy, interphase FISH for 13q14, 17p13, and 11q provides prognostically relevant information in addition to that provided by standard prognostic factors. This observation may be considered for risk-adapted stratifications of MM patients in future clinical trials.

Structural aberrations of the short arm of chromosome 2, mostly resulting in gains of 2p13∼16, have recently been described as being highly recurrent in Hodgkin and Reed-Sternberg (HRS) cells of classical Hodgkin lymphoma (cHL). As these gains consistently lead to increased copy numbers of the REL oncogene locus, we investigated the expression of the c-Rel protein in a series of 30 cHL cases with known genomic REL status as determined by comparative genomic hybridization and interphase cytogenetics. Expression of the c-Rel protein was investigated in 26 biopsies by immunohistochemistry. Distinct patterns were observed in HRS cells with no staining, cytoplasmic, and/or nuclear staining for c-Rel. All 13 samples with additional copies of the REL locus displayed nuclear staining for c-Rel, while 13 cHL samples lacking chromosome 2 (2p) gains displayed a significantly lower proportion or complete absence of HRS cells with nuclear c-Rel expression. Detailed analysis using combined immunophenotyping and interphase cytogenetics of individual HRS cells demonstrated that REL gains correlated with the presence of nuclear c-Rel staining. Additionally, in 2 cHL samples with translocation breakpoints in 2p13∼16, nuclear staining of c-Rel was observed; in one of them the staining pattern was indicative of a truncated c-Rel protein. The correlation between structural aberrations involving the REL locus and nuclear c-Rel accumulation in HRS cells qualifies REL as a target gene of the frequent gains in 2p in cHL. The data suggest thatREL aberrations are a genetic mechanism contributing to constitutive nuclear factor (NF)–κB/Rel activation in cHL.
