Primary mediastinal large B-cell lymphoma (PMLBCL): long-term results from a retrospective multicentre Italian experience in 138 patients treated with CHOP or MACOP-B/VACOP-B

The optimal treatment of primary mediastinal large B-cell lymphoma (PMLBCL) is still undefined. In the absence of randomised studies, we retrospectively analysed: (a) the effectiveness of two chemotherapy regimens (CHOP vs MACOP-B/VACOP-B) in complete remission (CR) achievement and event-free survival (EFS) and (b) the role of mediastinal involved-field radiotherapy (IF-RT) as consolidation. From 1982 to 1999, 138 consecutive patients affected by PMLBCL were treated in 13 Italian institutions with CHOP (43) or MACOP-B/VACOP-B (95). The two groups of patients were similar as regard to age, gender, presence of bulky mediastinal mass, pleural effusion, stage and international prognostic indexes category of risk. Overall, 75.5% of patients in CR received IF-RT as consolidation. Complete remission was 51.1% in the CHOP group and 80% in MACOP-B/VACOP-B (P<0.001). Relapse occurred in 22.7% of CHOP- and in 9.2% of MACOP-B/VACOP-B-treated patients (n.s.). Event-free patients were 39.5% in CHOP and 75.7% in the MACOP-B/VACOP-B group (P<0.001). The addition of IF-RT as consolidation improved the outcome, irrespectively of the type of chemotherapy (P=0.04). At a multivariate analysis, achievement of CR (P<0.0001) and type of CT (MACOP-B/VACOP-B) retained the significance for OS (P=0.008) and EFS (P=0.03). In our experience, MACOP-B/VACOP-B appears to positively influence OS and EFS in patients affected by PMLBCL, as compared to CHOP. Consolidation IF-RT on mediastinum further improves the outcome of CR patients

Rituximab combined with MACOP-B or VACOP-B and radiation therapy in primary mediastinal large B-cell lymphoma: a retrospective study

Background: Third-generation regimens (MACOP-B [methotrexate/leucovorin (LV)/doxorubicin/cyclophosphamide/vincristine/prednisone/bleomycin] or VACOP-B [etoposide/LV/doxorubicin/cyclophosphamide/vincristine/prednisone/bleomycin]) in combination with local radiation therapy seem to improve lymphoma-free survival of primary mediastinal large B-cell lymphoma (PMLBCL). Recently, the superiority of R-CHOP (rituximab plus cyclophosphamide/doxorubicin/vincristine/prednisone) over CHOP-like regimens has been demonstrated in elderly and younger patients with low-risk diffuse large B-cell lymphoma. Patients and Methods: Retrospectively, between February 2002 and July 2006, 45 previously untreated patients with PMLBCL were treated with a combination of a third-generation chemotherapy regimen (MACOP-B or VACOP-B), concurrent rituximab, and mediastinal radiation therapy. Results: Twenty-six (62%) patients achieved a complete response (CR), and 15 (36%) obtained a partial response after MACOP-B/VACOP-B plus rituximab. After radiation therapy, the CR rate was 80%. At a median follow-up of 28 months, among the 34 patients who obtained a CR, 3 relapsed after 16,19, and 22 months, respectively. Projected overall survival was 80% at 5 years; the relapse-free survival (RFS) curve of the 34 patients who achieved CR was 88% at 5 years. Conclusion: In this retrospective study, in patients with PMLBCL, combined-modality treatment using the MACOP-B/VACOP-B regimen plus rituximab induces a high remission rate, with patients having a > 80% chance of surviving relapse free at 5 years. In comparison with historical data on MACOP-B/VACOP-B without rituximab, there are no statistically significant differences in terms of CR and RFS rates

Health-related quality of life and sense of coherence among people with obesity : Important factors for health management

Objectives: The purpose of this study was to evaluate whether health-related quality of life and levels of sense of coherence among people with obesity are correlated with body mass index, age, and gender.Methods: A cross-sectional, descriptive research design was used. Subjects (n = 157) were selected from a sample of participants in an ongoing survey and had a body mass index &gt;30 kg/m2. Data were collected using the Short Form-36 Health Survey and the Sense of Coherence Scale.Results: The mean body mass index of women was higher than that of men. Compared to men, a greater proportion of women had a low sense of coherence. There was a significant relationship between low physical health and high body mass index. Female gender and older age correlated with a low sense of coherence and showed a significant association with high body mass index.Conclusion: To increase the health-related quality of life, people with obesity need support to help manage their life situation based on their individual needs and personal resources

Long-term efficacy and toxicity results of the FLUMIZ trial (fludarabine and mitoxantrone followed by yttrium-90 ibritumomab tiuxetan in untreated follicular lymphoma).

The radiosensitivity of lymphomas as well as the local targeted delivery of high doses of radiation make radioimmunotherapy (RIT) an attractive therapeutic option. RIT is indeed an underestimated tool. In follicular lymphoma (FL), RIT represents one of the most effective single agents. The two most commonly used radioimmunoconjugates are 90Y-ibritumomab tiuxetan (Zevalin\uae) and 131I-tositumomab, both based on murine anti-Cd20 antibodies. RIT has demonstrated efficacy in relapsed/refractory FL and was approved for this indication [1]. Subsequently, many trials have evaluated the role of RIT consolidation after initial tumor debulking with chemotherapy or immunochemotherapy [2] and several phase II studies supported these results [3\u20135]. We now report updated long-term efficacy and toxicity results of a multicenter nonrandomized phase II trial of fludarabine and mitoxantrone plus RIT (fludarabine, mitoxantrone, zevalin trial), demonstrating that this combination was safe and very effective in untreated FL patients

A 3-gene signature based on MYC, BCL-2 and NFKBIA improves risk stratification in diffuse large B-cell lymphoma

Recent randomized trials focused on gene expression-based determination of the cell of origin in diffuse large B-cell lymphoma could not show significant improvements by adding novel agents to standard chemoimmunotherapy. The aim of this study was the identification of a gene signature able to refine current prognostication algorithms and applicable to clinical practice. Here we used a targeted gene expression profiling panel combining the Lymph2Cx signature for cell of origin classification with additional targets including MYC, BCL-2 and NFKBIA, in 186 patients from 2 randomized trials (discovery cohort) (NCT00355199 and NCT00499018). Data were validated in 3 independent series (2 large public datasets and a real-life cohort). By integrating the cell of origin, MYC/BCL-2 double expressor status and NFKBIA expression, we defined a 3-gene signature combining MYC, BCL-2 and NFKBIA (MBN-signature), which outperformed the MYC/BCL-2 double expressor status in multivariate analysis, and allowed further risk stratification within the germinal center B-cell/unclassified subset. The high-risk (MBN Sig-high) subgroup identified the vast majority of double hit cases and a significant fraction of Activated B-Cell-derived diffuse large B-cell lymphomas. These results were validated in 3 independent series including a cohort from the REMoDL-B trial, where, in an exploratory ad hoc analysis, the addition of bortezomib in the MBN Sig-high subgroup provided a progression free survival advantage compared with standard chemoimmunotherapy. These data indicate that a simple 3-gene signature based on MYC, BCL-2 and NFKBIA could refine the prognostic stratification in diffuse large B-cell lymphoma, and might be the basis for future precision-therapy approaches

Fludarabine and mitoxantrone followed by yttrium-90 ibritumomab tiuxetan in previously untreated patients with follicular non-Hodgkin lymphoma trial: a phase II non-randomised trial (FLUMIZ)

Follicular lymphoma is the most common form of lymphoma in Europe and the USA. In this prospective, single-arm, open-labelled, multicentre non-randomised phase II trial (FLUMIZ [FLUdarabine, MItoxantrone, Zevalin] trial) we aimed to assess the efficacy and safety of fludarabine and mitoxantrone plus radioimmunotherapy in untreated patients with follicular non-Hodgkin lymphoma (NHL)
