Abstract
In B-cell precursor acute lymphoblastic leukemia, the initial leukemic cells share the same antigen receptor gene rearrangements. However, due to ongoing rearrangement processes, leukemic cells with different gene rearrangement patterns can develop, resulting in subclone formation. We studied leukemic subclones and their distribution in the bone marrow and peripheral blood at diagnosis. Antigen receptor gene rearrangements (IGH, IGK, TRG, TRD, TRB) were analyzed by next-generation sequencing in seven paired bone marrow samples and five paired bone marrow-peripheral blood samples. Background-thresholds were defined, which enabled identification of leukemic gene rearrangements down to very low levels. Paired bone marrow analysis showed oligoclonality in all 7 patients and up to 34 leukemic clones per patient. Additional analysis of evolutionary-related IGH gene rearrangements revealed up to 171 leukemic clones per patient. Interestingly, overall 86% of all leukemic gene rearrangements, including small subclones, were present in both bone marrow samples (range per patient: 72–100%). Paired bone marrow-peripheral blood analysis showed that 83% of all leukemic gene rearrangements in bone marrow were also found in peripheral blood (range per patient: 81–100%). Remarkably, in the paired bone marrow samples and paired bone marrow-peripheral blood samples the vast majority of leukemic gene rearrangements had a similar frequency (<5-fold frequency difference) (96% and 96% of leukemic rearrangements, respectively). Together, these results indicate that B-cell precursor acute lymphoblastic leukemia is generally highly oligoclonal. Nevertheless, the vast majority of leukemic clones, even the minor antigen receptor-defined subclones, are homogeneously distributed throughout the bone marrow and peripheral blood compartment.

Abstract
We analyzed the CDR3 region of 80 children with B-cell acute lymphoblastic leukemia (B-ALL) using the ImMunoGeneTics Information System and JOINSOLVER. In total, 108 IGH@ rearrangements were analyzed. Most of them (75.3%) were non-productive. IGHV@ segments proximal to IGHD-IGHJ@ were preferentially rearranged (45.3%). Increased utilization of IGHV3 segments IGHV3-13 (11.3%) and IGHV3-15 (9.3%), IGHD3 (30.5%), and IGHJ4 (34%) was noted. In pro-B ALL more frequent were IGHV3-11 (33.3%) and IGHV6-1 (33.3%), IGHD2-21 (50%), IGHJ4 (50%), and IGHJ6 (50%) segments. Shorter CDR3 length was observed in IGHV@6, IGHD7, and IGHJ1 segments, whereas increased CDR3 length was related to IGHV3, IGHD2, and IGHJ4 segments. Increased risk of relapse was found in patients with productive sequences. Specifically, the relapse-free survival rate at 5 years in patients with productive sequences at diagnosis was 75% (standard error [SE] ±9%), whereas in patients with non-productive sequences it was 97% (SE ±1.92%) (p-value =0.0264). Monoclonality and oligoclonality were identified in 81.2% and 18.75% cases at diagnosis, respectively. Sequence analysis revealed IGHV@ to IGHDJ joining only in 6.6% cases with oligoclonality. The majority (75%) of relapsed patients had monoclonal IGH@ rearrangements. The preferential utilization of IGHV@ segments proximal to IGHDJ depended on their location on the IGHV@ locus. Molecular mechanisms occurring during IGH@ rearrangement might play an essential role in childhood ALL prognosis. In our study, the productivity of the rearranged sequences at diagnosis proved to be a significant prognostic factor.

Abstract
Molecular response and monitoring of minimal residual disease (MRD) is becoming an essential part of most protocols for treating leukemia and lymphoma patients. Detection of abnormal clones by PCR analysis of complementarity determining regions (CDRs) in immunoglobulin genes is currently standard practice for diagnosis, but is not widely used to monitor MRD because of the low sensitivity of assays that use consensus primers. Use of specific primers can improve the sensitivity of the assay, but is a cumbersome, expensive, and time-consuming process. We developed a simple and cost-effective approach to detect MRD in B-cell malignancies that is usable in clinical laboratories. The new assay uses ligase chain reaction (LCR) to detect clonality. The sensitivity of the LCR assay is 1 per 500,000 cells, and it can detect all subclones that were present in the pretherapy diagnostic sample.

Abstract
We present a case of del(14)(q21) as a sole abnormality in a 4-year-old boy diagnosed with precursor B-cell acute lymphoblastic leukemia (pre-B ALL). To our knowledge, this is the first case of isolated del(14)(q21) in pre-B ALL. Two pretreatment bone marrow samples obtained 5 days apart were analyzed by cytogenetics. The G-banded karyotypes of the two samples were similar, differing only in the ratio of normal/abnormal metaphases detected. Both samples showed a del(14)(q21) as the only abnormality. Fluorescence in situ hybridization performed using the probes TEL/AML1 and immunoglobulin heavy chain (IGH) showed no fusion involving the TEL and AML1 genes and only a single IGH signal in 20% of the interphase cells analyzed.

Abstract
Sequence analysis of the immunoglobulin heavy chain genes (IgH) has demonstrated preferential usage of specific variable (V), diversity (D), and joining (J) genes at different stages of B-cell development and in B-cell malignancies, and this has provided insight into B-cell maturation and selection. Knowledge of the association between rearrangement patterns based on updated databases and clinical characteristics of pediatric acute lymphoblastic leukemia (ALL) is limited. We analyzed 381 IgH sequences identified at presentation in 317 children with B-lineage ALL and assessed the V(H)D(H)J(H) gene utilization profiles. The D(H)J(H)-proximal V(H) segments and the D(H)2 gene family were significantly overrepresented. Only 21% of V(H)-J(H) joinings were potentially productive, a finding associated with a trend toward an increased risk of relapse. These results suggest that physical location at the V(H) locus is involved in preferential usage of D(H)J(H)-proximal V(H) segments whereas D(H) and J(H) segment usage is governed by position-independent molecular mechanisms. Molecular pathophysiology appears relevant to clinical outcome in patients who have only productive rearrangements, and specific rearrangement patterns are associated with differences in the tumor biology of childhood ALL.

Abstract
Immunoglobulin (Ig) and T-cell receptor (TCR) gene rearrangements provide clonal markers useful for diagnosis and measurement of minimal residual disease (MRD) in acute lymphoblastic leukemia (ALL). We analyzed the sequences of Ig and TCR gene rearrangements obtained at presentation and relapse in 41 children with ALL to study clonal stability, which has important implications for monitoring MRD, during the course of the disease. In 42%, all original Ig and/or TCR sequences were conserved. In 24%, one original sequence was preserved but the other lost, and in 14% the original sequences were conserved with new sequences identified at relapse. In 20% only new sequences were found at relapse. Using primers designed from the novel relapse sequences, the relapse clone could be identified as subdominant clones in the diagnostic sample in 8 of 14 patients. Alteration of these clonal gene rearrangements is a common feature in childhood ALL. MRD detection should include multiple gene targets to minimize false-negative samples or include also multicolor flow cytometry. In some cases the leukemic progenitor cell might arise earlier in lineage before DHJH recombination but retain the capacity to further differentiate into cells capable of altering the pattern of Ig and/or TCR rearrangements.

Abstract
Detailed Southern blot and PCR analysis of Ig heavy (IGH), Ig kappa (IGK), T-cell receptor delta (TCRD), and TCR gamma (TCRG) genes were performed in 289 children with precursor-B-ALL in order to determine age-related Ig/TCR patterns and their implications for detection of minimal residual disease (MRD). Overall, IGH, IGK, TCRD, and TCRG gene rearrangements were detected in 98, 62, 90, and 58% of patients, respectively. The frequency of IGH and TCRD rearrangements was independent of rearrangements in one of the other three loci, whereas Ig kappa deleting element and TCRG rearrangements preferentially coincided. Southern blot analysis showed that oligoclonality of IGH, IGK, and TCRD was interrelated, that is, oligoclonality in one locus was related with a higher chance of oligoclonality in another locus. Combined Southern blot and PCR analysis revealed that Ig/TCR patterns were age related: children younger than 3 years or older than 10 years showed a higher prevalence of incomplete IGH rearrangements and a lower prevalence of IGK deletions, TCRG rearrangements, and TCRD rearrangements than children between 3 and 10 years. In addition, IGH oligoclonality was more frequent in the younger and older children. These age-related differences probably reflect ALL subsets with different cellular origin and differences in the duration of the preleukemic phase between the initial and final leukemogenetic hit. The more immature Ig/TCR gene rearrangement pattern in children younger than 3 years or older than 10 years resulted in relatively low numbers of potential MRD-PCR targets per patient, particularly if only monoclonal rearrangements were taken into account. These data provide insight into the immunobiological characteristics of Ig/TCR gene rearrangements in childhood precursor-B-ALL and form a useful basis for designing improved strategies for the identification and selection of MRD-PCR targets.

Abstract
Detection of minimal residual disease (MRD) has prognostic value in many hematologic malignancies, including acute lymphoblastic leukemia, acute myeloid leukemia, chronic myeloid leukemia, non-Hodgkin's lymphoma, and multiple myeloma. Quantitative MRD data can be obtained with real-time quantitative PCR (RQ-PCR) analysis of immunoglobulin and T-cell receptor gene rearrangements, breakpoint fusion regions of chromosome aberrations, fusion-gene transcripts, aberrant genes, or aberrantly expressed genes, their application being dependent on the type of disease. RQ-PCR analysis can be performed with SYBR Green I, hydrolysis (TaqMan) probes, or hybridization (LightCycler) probes, as detection system in several RQ-PCR instruments. Dependent on the type of MRD-PCR target, different types of oligonucleotides can be used for specific detection, such as an allele-specific oligonucleotide (ASO) probe, an ASO forward primer, an ASO reverse primer, or germline probe and primers. To assess the quantity and quality of the RNA/DNA, one or more control genes must be included. Finally, the interpretation of RQ-PCR MRD data needs standardized criteria and reporting of MRD data needs international uniformity. Several European networks have now been established and common guidelines for data analysis and for reporting of MRD data are being developed. These networks also include standardization of technology as well as regular quality control rounds, both being essential for the introduction of RQ-PCR-based MRD detection in multicenter clinical treatment protocols.

Abstract
Despite intensive chemotherapy and stem cell transplantation (SCT) programmes, overall survival in adult acute lymphoblastic leukaemia (ALL) remains poor compared to that in childhood ALL. Despite clinical and morphological remission being achieved by over 80% of patients, 5-year survival is limited to 40% of patients, clearly indicating that morphology is insufficient in predicting future outcome. Molecular assessment of residual disease in bone marrow using immunoglobulin genes as markers of clonality has recently been evaluated in a large adult ALL study in our institution. Analysis of disease-free survival (DFS) rates for minimal residual disease-(MRD-) positive and -negative patients established that MRD positivity was associated with increased relapse rates at all times, being most significant at 3-5 months post-induction and beyond. Pre-autologous SCT tests are predictive of outcome, but for allogeneic SCT outcome is related to results of the tests after the procedure rather than before. The association of MRD test results and DFS was independent of, and greater than, other standard predictors of outcome and is therefore important in determining treatment for individual patients.

Abstract
The term minimal residual disease (MRD) in its currently accepted application refers to low-level disease detected in a whole variety of clinical situations. It is used to describe residual disease after suboptimal induction chemotherapy, but at the same time refers to the lowest levels of disease potentially compatible with cure or to molecularly defined relapse after long-term remission. This discussion intends to redefine MRD into some biologically relevant subcategories which may warrant their own independent terminology.
