An artificial intelligence system applied to recurrent cytogenetic aberrations and genetic progression scores predicts MYC rearrangements in large B-cell lymphoma. EJHAEM 2022; 3:707-721.

Abstract
Diffuse large B-cell lymphoma (DLBCL), the most common type of non-Hodgkin lymphoma, is characterized by MYC rearrangements (MYC R) in up to 15% of cases, and these have unfavorable prognosis. Due to cryptic rearrangements and variations in MYC breakpoints, MYC R may be undetectable by conventional methods in up to 10%-15% of cases. In this study, a retrospective proof of concept study, we sought to identify recurrent cytogenetic aberrations (RCAs), generate genetic progression scores (GP) from RCAs and apply these to an artificial intelligence (AI) algorithm to predict MYC status in the karyotypes of published cases. The developed AI algorithm is validated for its performance on our institutional cases. In addition, cytogenetic evolution pattern and clinical impact of RCAs was performed. Chromosome losses were associated with MYC-, while partial gain of chromosome 1 was significant in MYC R tumors. MYC R was the sole driver alteration in MYC-rearranged tumors, and evolution patterns revealed RCAs associated with gene expression signatures. A higher GPS value was associated with MYC R tumors. A subsequent AI algorithm (composed of RCAs + GPS) obtained a sensitivity of 91.4 and specificity of 93.8 at predicting MYC R. Analysis of an additional 59 institutional cases with the AI algorithm showed a sensitivity and specificity of 100% and 87% each with positive predictive value of 92%, and a negative predictive value of 100%. Cases with a MYC R showed a shorter survival.

Abstract
The prognosis of patients with primary mediastinal large B-cell lymphoma has improved over recent years. However, the optimal treatment strategy including the role of radiotherapy remains unknown. We retrospectively analyzed the clinical outcomes of 345 patients with newly diagnosed primary mediastinal large B-cell lymphoma in Japan. With a median follow up of 48 months, the overall survival at four years for patients treated with R-CHOP (n=187), CHOP (n=44), DA-EPOCH-R (n=9), 2(nd)- or 3(rd)-generation regimens, and chemotherapy followed by autologous stem cell transplantation were 90%, 67%, 100%, 91% and 92%, respectively. Focusing on patients treated with R-CHOP, a higher International Prognostic Index score and the presence of pleural or pericardial effusion were identified as adverse prognostic factors for overall survival in patients treated with R-CHOP without consolidative radiotherapy (IPI: hazard ratio 4.23, 95% confidence interval 1.48-12.13, P=0.007; effusion: hazard ratio 4.93, 95% confidence interval 1.37-17.69, P=0.015). Combined with the International Prognostic Index score and the presence of pleural or pericardial effusion for the stratification of patients treated with R-CHOP without radiotherapy, patients with lower International Prognostic Index score and the absence of effusion comprised approximately one-half of these patients and could be identified as curable patients (95% overall survival at 4 years). The DA-EPOCH-R regimen might overcome the effect of these adverse prognostic factors. Our simple indicators of International Prognostic Index score and the presence of pleural or pericardial effusion could stratify patients with primary mediastinal large B-cell lymphoma and help guide selection of treatment.

Abstract
Peripheral T-cell lymphoma (PTCL) has a poorer prognosis than diffuse large B-cell lymphoma (DLBCL). We administered the CyclOBEAP regimen (cyclophosphamide, vincristine, bleomycin, etoposide, doxorubicin, prednisolone) to patients with DLBCL, and reported its safety and efficacy. Here, we report the results of a multicentre phase II study of the CyclOBEAP regimen in patients with PTCL. In addition, NME1 remained a prognostic factor for survival, as shown in patients who were treated with CyclOBEAP. There were 84 eligible patients and the median age was 54 years. The 5-year overall survival (OS) rate was 72% and progression-free survival (PFS) rate was 61%. The 5-year OS was 93% among the anaplastic large-cell lymphoma cases, 74% among the angioimmunoblastic T-cell lymphoma cases, and 63% among the cases of PTCL-not otherwise specified. When the patients were divided according to the International Prognostic Index or Prognostic Index for PTCL, the 5-year OS and PFS rates did not significantly differ among the risk groups. Positivity for NME1 was found to be a significant independent prognostic factor. Grade 4 neutropenia was observed in 80 patients and thrombocytopenia in nine patients. Our results suggest that the CyclOBEAP therapy is safe and effective for PTCLs. Furthermore, the NME1 protein may be an important prognostic factor in PTCL.

Abstract
PURPOSE We examined whether nm23-H1 is a prognostic factor of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). EXPERIMENTAL DESIGN We studied 102 consecutive, untreated PTCL-NOS patients from 1998 to 2008. The expression of nm23-H1 and TIA-1 was studied by immunohistochemistry. RESULTS nm23-H1 was positive in 44.1% and TIA-1 in 78.4% of the PTCL-NOS patients. nm23-H1 expression was not correlated with age, performance status (PS), lactate dehydrogenase (LDH) level, or stage but was significantly correlated with the prognostic index for T-cell lymphoma. The serum nm23-H1 level was 43.44 ng/mL in the cytoplasmic nm23-H1 strongly positive, 24.32 ng/mL in the cytoplasmic nm23-H1 moderately positive, and 13.64 ng/mL in the cytoplasmic nm23-H1-negative patients. The nm23-H1-positive group had significantly shorter overall survival (OS). TIA-1 had no prognostic impact on 5-year OS rates. OS was significantly shorter in patients with the following clinicopathologic features: age 60 or more years, PS of 2 to 4, LDH level greater than normal, bone marrow involvement, or nm23-H1-positive lymphoma. Multivariate analysis confirmed nm23-H1 expression to be an independent prognostic factor. CONCLUSIONS The nm23-H1 protein may be an important prognostic factor in PTCL-NOS. Because our results suggested that nm23-HI is produced by lymphoma cells, we expect to see the development of new treatments targeting nm23 overexpression.

Abstract
The R-CHOP regimen has been found to improve the outcome of diffuse large B-cell lymphoma (DLBCL). However, it does not provide a satisfactory treatment outcome in the high-risk group. We previously administered the CyclOBEAP regimen to patients with DLBCL, and reported its safety and efficacy. The R-CyclOBEAP regimen was administered over a total period of 12 weeks, and rituximab 375 mg/m(2) was given every 2 weeks. There were 101 eligible patients. CR was achieved in 96 patients (95%). The 5-year overall survival (OS) rate was 85% and progression-free survival (PFS) rate was 76%. When the patients were divided according to the IPI, the 5-year OS and PFS rates did not significantly differ among the risk groups. The 5-year PFS of the germinal centre B-cell group was 80% and that of the non-GCB group was 74% (NS). Univariate analysis showed that the presence of B symptoms, extranodal lesions >or=2, and sIL-2R were significant poor prognostic factors. Grade 4 neutropenia was observed in 91 patients and thrombocytopenia in 9 patients. The addition of rituximab to CyclOBEAP therapy may enhance the effect of CyclOBEAP therapy for DLBCL.

Abstract
Among methotrexate (MTX)-related lymphoproliferative disorders (MTX-LPD), diffuse large B-cell lymphoma (DLBCL) accounts for about half. We studied the clinicopathological characteristics and prognosis of patients with DLBCL in MTX-LPD. This study included 29 patients who developed DLBCL after receiving MTX for rheumatoid arthritis. MTX was discontinued in all patients. Their median age was 62 years. Elevated lactate dehydrogenase (LDH) level was observed in 97% of the patients, bone marrow involvement in 17%, and involvement of extranodal sites in 41%. As for the cellular immunophenotype, CD20 was positive in 93%, CD5 in 3%, CD10 in 31%, BCL2 in 21%, BCL6 in 69%, and Epstein-Barr virus (EBV)-encoded small non-polyadenylated RNA (EBER) in 24%. Chemotherapy was started within 2 months after MTX withdrawal in 23 patients, of whom 12 patients received combination with rituximab. Spontaneous remission occurred in the remaining six patients. The EEBV-positive rate was 67% (4/6), and the four EBV-positive patients achieved complete response. Among the 23 DLBCL patients treated with chemotherapy, 20 patients achieved complete response. The 5-year overall survival was 74% and the 5-year progression-free survival was 65%. After the development of DLBCL, withdrawal of MTX was the first choice of treatment. Germinal center B-cell type and EBER-positive patients tended to show spontaneous remission. The utility of rituximab should be examined in future studies.

Abstract
Diffuse large B-cell lymphoma (DLBCL) has heterogeneous clinical, histological, and molecular features. We evaluated the clinical characteristics and prognoses of patients with DLBCL carrying 8q24 translocations. A total of 1864 consecutive patients with non-Hodgkin's lymphoma were treated in the Adult Lymphoma Treatment Study Group from 1998 to 2005. Of the 252 patients with DLBCL with abnormal karyotypes, 28 patients with DLBCL with the 8q24 translocation were identified. There were 14 men and 14 women, with a median age of 61 years. The 8q24 translocation was observed significantly more frequently among patients with poor performance status, among patients with high lactate dehydrogenase level, and among patients with bone marrow involvement. The 5-year overall survival was 43.9% among the patients with 8q24 translocation, and 67% among the patients with other chromosomal abnormalities. The 8q24 translocation group showed significantly poorer prognosis than the group with other translocations. In addition, patients with t(14;18) and 8q24 translocation showed significantly poorer prognosis than those with 8q24 translocation alone. It will be necessary to study whether more aggressive chemotherapy or rituximab combination chemotherapy is effective in 8q24 translocation cases.

Abstract
Diffuse large B-cell lymphoma (DLBCL) having both t(14;18) and 8q24 translocations is rare. We evaluated the clinical characteristics and prognoses of patients with DLBCL carrying both t(14;18) and 8q24 translocations. A total of 1972 patients with non-Hodgkin's lymphoma were treated in the Adult Lymphoma Treatment Study Group (ALTSG) from 1998 to 2007. Nineteen cases of de novo DLBCL with the dual translocation were identified. The dual translocation was observed in 19 of 394 patients with DLBCL (10 males and 9 females, with a median age of 61 years). The dual translocation was observed significantly more frequently among patients with high lactate dehydrogenase levels, B symptoms, bone marrow involvement and advanced stage. Immunophenotyping was performed and showed DLBCL with a germinal center type in the majority of cases. Progression-free survival and overall survival rates were significantly lower in patients with the dual translocation than in those with other translocation. DLBCL patients with concurrent t(14;18) and 8q24 translocations have very poor prognosis. Even if patients had a complete response to chemotherapy, they subsequently suffered early relapse. In this study, only a few patients received rituximab, and its usefulness could not be assessed. Future studies with larger numbers of patients are required.

Among the 59 patients having 3q27 translocation, 10.9% had follicular lymphoma (FL) and 23.1% had DLBCL. It is of interest that the prognostic significance was not found between FL and DLBCL with 3q27 translocations. Progression-free survival (PFS) rate was significantly higher in the FL patients with 3q27 translocation than in those with 18q21 translocation. PFS rate was significantly higher in the DLBCL patients with 3q27 translocation than in those with 18q21 translocation. These findings suggest that the presence of 3q27 translocation is a significant prognostic factor in DLBCL.

Abstract
We treated elderly patients (65-69 years) who had aggressive lymphoma with the CyclOBEAP regimen, and we studied the safety and efficacy of this treatment. The CyclOBEAP regimen was administered over a total period of 12 weeks. Doxorubicin 40 mg/m(2) was given every 2 weeks in combination with either cyclophosphamide 800 mg/m(2) or etoposide 70 mg/m(2) qd x 3. During the alternate weeks, non-myelosuppressive vincristine 1.0 mg/m(2) was given either with bleomycin 10 mg/m(2) or alone. Prednisolone 40 mg/m(2) was administered daily for three 14-day periods during weeks 1-2, 5-6 and 9-10. There were 51 eligible patients. A complete response was achieved in 42 patients (82%). The 5-year overall survival (OS) rate was 60.6% and progression-free survival (PFS) rate was 51.8%. WHO grade 4 neutropenia was observed in 32 patients and thrombocytopenia in 8 patients. We showed that the CyclOBEAP regimen can be safely used in the treatment of aggressive lymphoma in elderly patients and it achieved a high rate of remission.
