Abstract
Four cases with a segmental amplification of 11q23 region were detected by FISH. The amplifica-tion was either contiguous amplification on chromosome 11, or multiple markers involving the11q23 region. The markers were derivative chromosomes, or isochromosomes. Amplification of11q23 region was associated with complex karyotypes at the time of diagnosis or following treat-ment in secondary leukemias. Three were AML cases belonging to either AML-M5a or AML-1subtypes and one was a myeloproliferative disorder. These cases were resistant to treatment. Con-ventional cytogenetic analysis and fluorescence in situ hybridization (FISH) studies using MLL, 11painting, or 11 centromere probes ascertained the segmental amplification. Since the patients didnot respond to treatment the amplification of gene or genes that map to 11q23 may be responsiblefor the unfavorable prognosis. Hence, this type of amplifications could have clinical significance.

1. Introduction
Genomic amplification of oncogenes has been observedfrequently in solid tumors and is less common in hematogicalmalignancies. The amplifications manifest as double minutes(dmin) or homogeneously staining regions (HSR). The esti-mated incidence of cytogenetically detectable gene amplifi-
cation in AML is
z
1% [1]. FISH/molecular investigation ofsuch amplifications have been limited. In AML, the ampli-cons have most frequently been C-MYC [2,3]. MLL

HSR in AML have been reported recently [4–6].In this article, the focus is on patients with myeloid dis-
orders and 4–9 copies of the 11q23-segment encompassingMLL. The amplifications of 11q23 segment are either onchromosome 11, i.e., intrachromosomal or on another chro-mosome, i.e., interchromosomal [1,5,7–10].
Tanaka et al. [1], identified a segmental jumping translo-cation containing the CD3-MLL region as a new form ofgene amplification in a treatment related leukemia with a
complex karyotype. The leukemia was of French-American-British (FAB) M1 morphologic subtype and occurred follow-ing 5-fluorouracil chemotherapy for the management ofbreast tumor. This patient had 4 copies of CD3-MLL region.Felix et al. [7] studied a treatment related acute myeloid leu-kemia (t-AML) case with a complex karyotype. FISH analy-sis showed multiple copies of the MLL gene. A genomic re-gion including CD3
e
, MLL and a segment of band 11q24was unrearranged and amplified by Southern-blot analysis.Cuthbert et al. [9] described a jumping translocation of 11q23with MLL gene rearrangement and interstitial telomeric se-quences. A marker with interspersed chromosome 9 and 11regions and also involving chromosome 19 was reported byAllen et al. [8]. In one AML-M4 patient, Avet-Loiseau et al.[5] found a complex karyotype with multiple MLL signals ona ring and marker chromosomes post breast cancer treatmentfor 5 years. A second patient had de novo AML-M1 andmarker chromosomes with multiple MLL signals. Both pa-tients were refractory to treatment. Size variable ring chromo-somes in a AML-M4 and AML-M5a case and a homoge-nously staining region with MLL amplification in a AML-M6case was reported by Streubel et al. [6]. Reddy et al. [10] de-scribed a chromosome 11 with 2–3 copies of 11q23-MLL re-

gion. In this paper, we present four cases with multiple copiesof 11q23-MLL segment resulting from direct duplication ormultiple copies of a derivative chromosome involving 11q23.Case 1 has been previously published [10].
Partial tandem duplication of the MLL gene has been ob-served in
z
5% of AML patients with normal cytogenetics[11–13]. However, MLL gene duplications are regularlygenerated by homologous ALU recombination in a smallnumber of hematopoietic cells of most healthy donors.These data suggests that MLL gene duplications are not im-plicated in the malignant transformation in AML, or alter-nately only a few cells acquire additional oncogenic muta-tions necessary to establish the malignant phenotype [14].
Second cancers occur in
z
7% of survivors of a primarymalignancy [15]. Leukemias are the major second cancerthat result from chemotherapy [16–18]. The two majorforms of treatment related leukemias are those with chro-mosome 5 and 7 monosomies induced by alkylating agentsand those with MLL gene translocations and other translo-cations related to topoisomerase II inhibitors [7].
2. Clinical history
2.1. Case 1
A 66-year-old Caucasian male was diagnosed with my-eloproliferative disorder (MPD) 10 years ago. The thrombo-cytosis was treated with hydroxyurea for 1 1/2 years. In1994 and 1997, the patient was again prescribed hydrox-yurea and was given frequent blood transfusions. The RT-PCR was negative for BCR/ABL fusion transcript. Re-cently, he developed a persistent cough. Chest X-rayshowed bilateral interstitial pulmonary infiltrates. The blasts(68%) were consistent with acute myeloid leukemia and fa-vored the subclass M5a. Flow cytometry studies supportedthis diagnosis. The presence of trilineage dysplasia raisedthe possibility of treatment-related acute myeloid leukemia.
2.2. Case 2
An 82-year-old woman presented with progressive pancy-topenia. Sixteen years ago she had right radical mastectomy

with axillary dissection finding of
,
1 cm infiltrating lobularcarcinoma for which treatment was declined. Four years later,she had a left radical mastectomy with axillary dissection for a2.5 cm infiltrating ductal carcinoma. Three lymph nodes werepositive. She received 6 courses of CMF chemotherapy withIV cyclophosphamide and Tamoxifen for 1 year. A year ago,she had painless vaginal bleeding and had hysterectomy, bilat-eral salpingo-oophorectomy because of a malignant Mullerianmixed tumor. The patient underwent external beam radiother-apy to the pelvis. A diffuse large B-cell lymphoma presentedas a right hilar mass in the lung. She had partial remission ofher lung disease after CHOP chemotherapy four times withdose reduction. The significant pancytopenia that ensued re-quired erythropoietin and G-CSF, growth factor support. After4 weeks of treatment, she achieved partial remission and re-ceived weekly rituximab (monoclonal antibody directedagainst CD20) 375 mg/M

. Because of progressive pancy-topenia flow cytometry and cytogenetics studies on a bonemarrow biopsy, was performed and found to be consistentwith acute myeloid leukemia probably of FAB subclass M1.The patient was in hospice care and had received chronictransfusions. Four months later the patient passed away.
2.3. Case 3
A 78-year-old woman presented with gingivitis of the ante-rior mouth, fever, chills and decreased appetite. She has had ahistory of a hysterectomy and a bilateral salpingo-oophorec-tomy for an abnormal PAP smear. The CBC showed mildanemia with a hemoglobin of 8–9 gm/dl and platelets 41

/L. The smear had 100% blasts, presumably of myelocyticorigin. In flow cytometry studies, the majority of the cellswere positive for HLA-DR, CD13, CD33, CD34 and cyto-plasmic myeloperoxidase and was compatible with myelo-blasts of the M1 FAB subclassification. Following treatmentwith idarubacin and infusion ARA-C, she went into partial re-mission and lived for 6 months following AML diagnosis.
2.4. Case 4
An 86-year-old white male was admitted because of sud-den onset of hemoptysis. He had a respiratory infection forseveral weeks and was running a slight temperature. Earlier,he was diagnosed with myeloproliferative disorder in 1994and was treated with hydroxyurea to control his platelet count.He was noted recently to have some immature white cells and

was investigated for leukemic transformation. A week afterthe cytogenetic study the patient passed away. He had low-grade transitional cell carcinoma in 1981 and was under sur-veillance cytoscopies. A pilonidal cysts was removed. A rightcarpal tunnel release was also performed. He had a benignprostatic hyperthrophy and hypothyoidism. One brother andsister died of lung cancer at 41 years and 81 years of age.
3. Material and methods
Unstimulated bone marrow cultures were harvested after24 and 48 hours. The slides were GTG-banded.
Fluorescence in situ hybridization (FISH) was performedusing coatasome-11, MLL, or D11Z1 probes (Ventana Inc.,Gaithesburg, MD, USA). The MLL probe used detectsabout 80% of the rearrangements except those that occur inthe 3

5. Discussion
The cases in this study were compared to other reportedcases with 11q23–MLL segmental rearrangements (Table 2)[1,5–10]. The segmental rearrangements included duplicationand triplication of 11q23 region on chromosome 11 or asmarkers involving this region. Eight were males and 5 werefemale. Their ages ranged from 2–86 years. Eight were pri-mary myeloid disorder cases, 5 were secondary acute myeloidleukemia following treatment with 5-fluorouracil for breastcancer; vincristine, actinomycin D, ifosfamide, cyclophospha-mide, etopside, doxorubicin, carboplatinum treatment for em-bryonal rhabdomyosarcoma; hydroxyurea for myeloprolifera-tive disorder and CMF chemotherapy with IV Cytoxan andTamoxifen for breast cancer and CHOP chemotherapy forB-cell lymphoma. The treatment related acute myeloid leuke-mia were AML-M1, AML-M4, AML-M5, and AML-5a. Theduration between primary malignancy and secondary leuke-

mia ranged from 2–10 years. Survival after the secondary leu-kemia ranged from 2 days to 4 months. Apart from monosomy5 and 7 which are associated with treatment related leukemia,duplication of 11q23–MLL region may be yet another therapyrelated abnormality to be considered in the future.
The intrachromosomal change in this study included seg-mental duplication or triplication of 11q23 region. A roughestimate of the incidence of 11q23 segmental amplificationsis 4/690 (0.57%) in myeloid disorder cases. Interestingly, incase 1, MLL region amplification increased from 2 copies to3 copies in a sideline. This suggests that the region is dy-namic and probably subject to duplication by unequal cross-ing over. In cases 2 to 4 the multiplication of the derivativechromosome with 11q23 segment, suggests a growth advan-tage to these cells and hence their selective retention.
In our experience, the segmental duplications and theirvarious manifestations were hard to detect using G-bandingalone. Multiple copies of marker chromosomes and deriva-tive chromosomes also required FISH studies to confirm thechromosomal origin. The role of 11q23 amplifications in leu-kemogenesis may involve over expression of either MLLand/or other genes that map to this region. Therefore, in mye-loid disorders possible 11q23 rearrangements should be eval-uated using FISH/molecular studies to detect 11q23–MLLamplification and this may identify cases that are probably re-sistant to treatment and have an unfavorable prognosis.
