Abstract
Therapy-related myeloid neoplasms (t-MN) are a distinct subgroup of myeloid malignancies with a poor prognosis that include cases of therapy-related myelodysplastic syndrome (t-MDS), therapy-related myeloproliferative neoplasms (t-MPN) and therapy-related acute myeloid leukemia (t-AML). Here, we report a series of patients with clinical features consistent with juvenile myelomonocytic leukemia (JMML), an overlap syndrome of MDS and myeloproliferative neoplasms that developed after treatment for another malignancy.

Abstract
Balanced chromosome rearrangements are the hallmark of therapy-related leukemia that develops in patients treated with topoisomerase II inhibitors. Many of these rearrangements involve recurrent chromosomal sites and associated genes (11q23/MLL, 21q22.3/AML1, and 11p15/NUP98), which can interact with a variety of partner genes. One such rearrangement is the rare t(1;11)(q23;p15), which involves juxtaposition of the homeobox gene PMX1 (PRRX1) and NUP98. We report on an additional patient with t(1;11) who presented with myelodysplastic syndrome (MDS) subsequent to treatment for a pleomorphic liposarcoma. With time, the patient's disorder progressed to acute myelomonocytic leukemia with cytogenetic evidence of clonal evolution. To our knowledge, this is the first report of a patient presenting with a myelodysplastic syndrome with isolated t(1;11) (q23;p15), which evolved into therapy-related acute myeloid leukemia (t-AML). This patient is the third reported with this cytogenetic rearrangement and t-AML, and is compared with the other two reports of t(1;11)(q23;p15).

Abstract
On the basis of their ever-expanding roles, not only in sensory signaling but also in a plethora of other, often Ca(2+)-mediated actions in cell and whole body homeostasis, it is suggested that mutations in TRP channel genes not only cause disease states but also contribute in more subtle ways to simple and complex diseases. A survey is therefore presented of diseases and syndromes that map to one or multiple chromosomal loci containing TRP channel genes. A visual map of the chromosomal locations of TRP channel genes in man and mouse is also presented.

Abstract
Acute leukemias with balanced chromosomal translocations, protean morphologic and immunophenotypic presentations but generally shorter latency and absence of myelodysplasia are recognized as a complication of anti-cancer drugs that behave as topoisomerase II poisons. Translocations affecting the breakpoint cluster region of the MLL gene at chromosome band 11q23 are the most common molecular genetic aberrations in leukemias associated with the topoisomerase II poisons. These agents perturb the cleavage-religation equilibrium of topoisomerase II and increase cleavage complexes. One model suggests that this damages the DNA directly and leads to chromosomal breakage, which may result in untoward DNA recombination in the form of translocations. This review will summarize the evidence for topoisomerase II involvement in the genesis of translocations and extension of the model to acute leukemia in infants characterized by similar MLL translocations.

Abstract
Acute leukemias with thrombocytosis have been recently linked with structural abnormalities of the short arm of chromosome 3. A 46-year-old man with a 2-month history of recurrent transient ischemic attacks and abdominal pain developed an ischemic left foot and a gangrenous toe as his initial symptoms. Platelet count was 3.5 x 10(6)/microL, and despite plateletpheresis, the patient required left-leg amputation. Pathologic examination was remarkable for arterial thrombosis in the absence of atherosclerotic lesions. A diagnosis of acute myeloid leukemia with a novel translocation between chromosomes 3q21, 16, and 7 was made. Induction therapy was unsuccessful, and the patient died of overwhelming sepsis within 5 weeks of diagnosis. The striking features of this case were extreme symptomatic thrombocytosis, peripheral gangrene without atherosclerosis, and a novel three-way chromosomal translocation involving chromosome 3q21.

Abstract
Chromosomal anomalies involving region 3q21q26 have been reported associated with thrombocytosis in various hematological malignancies, such as chronic myeloid leukemia, myelodysplastic syndrome, and acute myeloid leukemia (AML). Recent reports described the association of central diabetes insipidus with AML and chromosomal anomalies involving region 3q21q26. We review the database in our institution and report five cases of inv(3)(q21q26) in consecutive cytogenetic studies of AML and myelodysplastic syndromes from 1992 to 2000, two cases presented as sole abnormalities and three cases were associated with monosomy 7. Only one case was associated with central diabetes insipidus. The literature of 3q21q26 syndrome and central diabetes insipidus in myeloid leukemia is reviewed.

Abstract
Seventy-seven patients were identified with Rare recurring (excluding 11q23, 21q22, inv(16), and t(15;17)) chromosome abnormalities among 511 patients with treatment-related myelodysplastic syndromes and acute leukemia accepted from centers in the United States, Europe, and Japan. The abnormality subsets included 3q21q26 (17 patients), 11p15 (17 patients), t(9;22)(q34;q11) (10 patients), 12p13 (9 patients), t(8;16)(p11;p13) (9 patients), and an "other" subset, which included t(6;9)(p23;q34) (3 patients), t(10;11)(p13;q13 approximately q21) (3 patients), t(1;17)(p36;q21) (2 patients), t(8;14)(q24;q32) (2 patients), t(11;19)(q13;q13) (2 patients), t(1;3)(p36;q21) (2 patients), and t(3;5)(q21;q31) (1 patient). Increased karyotypic complexity with additional balanced and unbalanced rearrangements was observed in 70% of cases. Among 54 cases with secondary abnormalities, chromosome 5 and/or 7 abnormalities were observed in 59%. The most frequent primary diseases were breast cancer (24 cases), Hodgkin disease (14 cases), non-Hodgkin lymphoma (10 cases), and de novo ALL (5 cases). Thirty-seven patients received alkylating agents plus topoisomerase II inhibitors with or without radiation therapy. The presenting diagnosis was t-AML in 47 cases, t-MDS in 23 cases (10 progressed to t-AML), and t-ALL in seven cases, five of whom had a t(9;22). The median latency time from initiation of original therapy to therapy-related disease diagnosis was quite long (69 months), and the overall median survival from the date of therapy-related disease diagnosis was very short (7 months). The 1-year survival rate was 34 +/- 7%, with no significant differences among subsets. Comparison with previously reported cases showed increased karyotypic complexity and adult presentation of pediatric-associated chromosome abnormalities.

Abstract
Acute leukemia is associated with a wide spectrum of recurrent, non-random chromosomal translocations. Molecular analysis of the genes involved in these translocations has led to a better understanding of both the causes of chromosomal rearrangements as well as the mechanisms of leukemic transformation. Recently, a number of laboratories have cloned translocations involving the NUP98 gene on chromosome 11p15.5, from patients with acute myelogenous leukemia (AML), myelodysplastic syndrome (MDS), chronic myelogenous leukemia (CML), and T cell acute lymphoblastic leukemia (T-ALL). To date, at least eight different chromosomal rearrangements involving NUP98 have been identified. The resultant chimeric transcripts encode fusion proteins that juxtapose the N-terminal GLFG repeats of NUP98 to the C-terminus of the partner gene. Of note, several of these translocations have been found in patients with therapy-related acute myelogenous leukemia (t-AML) or myelodysplastic syndrome (t-MDS), suggesting that genotoxic chemotherapeutic agents may play an important role in generating chromosomal rearrangements involving NUP98.

Abstract
The epipodophyllotoxins etoposide and teniposide and other DNA topoisomerase II inhibitors including anthracyclines and dactinomycin are highly efficacious anticancer drugs. All are associated with a distinct form of leukemia characterized by chromosomal translocations as a treatment complication. Most of the translocations disrupt a breakpoint cluster region (bcr) of the MLL gene at chromosome band 11q23. Other characteristic translocations also may occur. The normal function of the nuclear enzyme DNA topoisomerase II is to catalyze changes in DNA topology between relaxed and supercoiled states by transiently cleaving and re-ligating both strands of the double helix. Anticancer drugs that are DNA topoisomerase II inhibitors are cytotoxic because they form complexes with DNA and DNA topoisomerase II. The complexes decrease the re-ligation rate, disrupt the cleavage-re-ligation equilibrium, and have a net effect of increasing cleavage. The increased cleavage damages the DNA and leads to chromosomal breakage. Cells with irreparable DNA damage die by apoptosis. The association of DNA topoisomerase II inhibitors with leukemia suggests that the drug-induced, DNA topoisomerase II-mediated chromosomal breakage may be relevant to translocations in addition to this anti-neoplastic, cytotoxic action. Epidemiological studies, genomic translocation breakpoint cloning and in vitro DNA topoisomerase II cleavage assays together lead to a model for treatment-related leukemia in which DNA topoisomerase II causes chromosomal breakage and translocations form when the breakage is repaired.

Abstract
Chromosomal aberrations are frequently associated with therapy-related myelodysplastic syndromes and acute myelogenous leukemia (t-MDS/AML) and are thought to result from exposure to genotoxic drugs, including alkylating agents and DNA topoisomerase II poisons. The NUP98 gene on chromosome band 11p15 is involved in several different chromosomal aberrations that have been associated with t-MDS/AML. We have cloned the translocation breakpoints from two cases of t-MDS harboring a t(11;20)(p15;q11). Sequence analysis of the breakpoints from both cases revealed almost perfectly balanced translocations between NUP98 and TOP1. There were no known recombinogenic sequences identified at or near the breakpoints. However, four bp microduplications present at the translocation crossover points suggested that these translocations may have been initiated by 4 bp staggered double-stranded DNA breaks, which are known to be associated with the action of topoisomerase II. Given the history of patient exposure to topoisomerase II poisons, and the fact that these drugs stabilize staggered breaks with a 4 bp overhang, it seems possible that drug-induced topoisomerase II cleavage and subunit exchange was involved in these translocations. These results suggest that NUP98 is a recurrent target for therapy-related malignancies induced by multiagent chemotherapy, and suggest a role for DNA topoisomerase II poisons in the generation of these translocations.

Abstract
Cytogenetic studies were performed on 80 pediatric cancer patients to observe the chromosomal damage, both quantitative and qualitative, induced by chemotherapy. Peripheral blood lymphocytes (PBL) (n = 127) were obtained at diagnosis, during treatment, at remission, and at relapse, and chromosome analysis performed utilizing G-banding standard procedures. The results show a significant increase in the number of altered karyotypes (P = 0.03) in the samples during treatment, returning to values that were similar to those at diagnosis at 2-year remission. Most of the chromosomal aberrations (CA) detected during the chemotherapy regimens were nonclonal, unbalanced (75%), and involved chromosomes 1, 3, 5, 6, 11, 12, 16, and 17 most frequently. There was also a marked increase of CA in samples at relapse with very similar features (type and distribution) to those detected during treatment. There was a good correlation between the chromosomal breakpoints in our series and fragile sites (58%), oncogene (75%), and tumor suppressor gene (33%) loci described in the literature. The results obtained suggest that cytostatic drugs induce a transient increase in chromosome fragility occurring at several cancer-associated breakpoints.

Abstract
We describe a case of an acute myelogenous leukemia (AML) associated with t(1;11) (q23;p15), which is a novel simple variant translocation of t(7;11)(p15;p15). The patient was a Japanese man who had a history of non-Hodgkin lymphoma (NHL) and received MACOP-B combination chemotherapy. Fifteen months after the completion of the treatment, the patient developed AML (M2), which was regarded as a therapy-related leukemia. Cytogenetic study of bone marrow cells showed t(1;11). Although he achieved complete remission by combination chemotherapy, a relapse of NHL and gastric cancer were revealed in the course of the consolidation chemotherapy for AML. The NHL was considered a histological conversion from follicular lymphoma because lymphoma cells carried t(14;18) (q32;q21) and were strongly positive for BCL2 protein. Translocation (1;11), together with AML having t(7;11) or inv(11) involving 11p15, shows that 11p15 is a common acceptor site of these chromosome aberrations and suggests the significance of the NUP98 gene located in 11p15 in therapy-related leukemia.

Abstract
The NUP98 gene is involved in 3 distinct chromosomal rearrangements, t(7;11)(p15;p15), t(2;11)(q31;p15), and inv(11)(p15q22); all of these NUP98 rearrangements have been identified in the malignant cells of patients with therapy-related acute myelogenous leukemia or myelodysplastic syndrome (t-AML/MDS). Here we report the cloning and characterization of a t(11;20)(p15;q11) translocation from patients with t-MDS. The breakpoint on chromosome 11p15 targets the NUP98 gene and results in the separation of the N-terminal FXFG repeats from the RNA-binding domain located in the C-terminus. The breakpoint on chromosome 20q11 occurs within the gene encoding human DNA topoisomerase I (TOP1). As a result, a chimeric mRNA encoding the NUP98 FXFG repeats fused to the body of DNA topoisomerase I is produced. These results indicate that NUP98is a recurrent target in therapy-related malignancies, and thatTOP1 is a previously unrecognized target for chromosomal translocations.

Abstract
Molecular rearrangements of the MLL gene at the 11q23 region have been identified in most cases of infant leukemia, regardless of the phenotype. We present a case of acute myeloid leukemia which coexpressed myeloid and lymphoid markers in a 12-month-old girl. Karyotype analysis revealed the presence of a thus far unreported translocation t(10;11)(p13;p15). Although no 11q23 abnormalities were cytogenetically detectable, an MLL gene molecular rearrangement was found.

Abstract
The cytogenetic hallmark of the Ewing family of tumors is t(11,22)(q24;q12) in its simple, complex or variant forms and/or its molecular equivalent EWS/FLI, EWS/ERG rearrangement. Additional secondary consistent chromosomal aberrations include the der(16)t(1;16) and frequently, other chromosome 1q abnormalities leading to 1q overdosage. We studied whether these secondary cytogenetic changes are correlated to clinical features and phenotypic expression which may have a prognostic impact. Successful cytogenetic evaluation was performed in eight patients with a Ewing family tumor. In four of these, in addition to the primary aberration, chromosome 1q overdosage (including two with der (16)t(1;16)) was noted. Out of these four patients, two had metastatic disease at the time of evaluation, while in the other four, disease was localized. Morphologically, the tumors with the additional 1q aberration, revealed the pPNET subtype more frequently than the typical Ewing. They also expressed a higher degree of neural differentiation by neural marker immunocytochemistry, in comparison to tumors without the 1q aberration. Determination of the prognostic significance of this finding requires a longer follow-up with a larger group of patients.

Abstract
In Ewing sarcoma and related tumors, recently referred to as the Ewing tumors (ET), t(11;22)(q24q12) and its molecular genetic equivalent, the EWS/FLI-1 rearrangement, characterize approximately 85% of cases, while variant aberrations are rare. A second nonrandom aberration in ET is the unbalanced t(1;16) accompanying the t(11;22) in roughly 17% of cases. We present a 17-year-old man with estraosseous ET and multiple metastases, in whom the only cytogenetically detectable chromosomal aberration was der (16)t(1;16)(q12;q11.2). This finding was confirmed by fluorescence in situ hybridization (FISH). Using the RT-PCR technique, a variant EWS/ERG fusion transcript was noted, resulting from a t(21;22) chromosomal rearrangement which recently demonstrated in roughly 10% of ET. However, data on possible biologic differences in EWS/FLI-1 versus EWS/ERG expressing ET are as yet unavailable. This is the first reported combination of t(1;16) with the EWS/ERG rearrangement. A possible significance of this finding for Ewing tumor progression is discussed.
