The study included patients with HL relapsing or refractory after three lines of chemotherapy (including brentuximab-vedotin) and autoHSCT, or four lines of chemotherapy if the patient was not eligible for HSCT. To assess whether some patients might be cured with nivolumab alone as systemic treatment, we analysed the 19 patients who achieved a CR and did not receive a consolidation (concomitant radiotherapy was performed in five patients). Can nivolumab alone cure patients with relapse or refractory Hodgkin lymphoma?. [Extracted from the article]

Purpose: We explored the potential overall survival (OS) benefit of bleomycin, etoposide, doxorubicin (Adriamycin), cyclophosphamide, vincristine (Oncovin), procarbazine, and prednisone (BEACOPP) over doxorubicin (Adriamycin), bleomycin, vinblastine, and dacarbazine (ABVD) in a pooled analysis of four randomized trials. Patients and methods: Primary objective was to evaluate the OS impact of BEACOPP using individual patient data. Secondary objectives were progression‐free survival (PFS), secondary cancers, and use of autologous stem cell transplantation (ASCT). Results: About 1227 patients were included. The 7‐year OS was 84.3% (95% CI 80.8‐87.2) for ABVD vs 87.7% (95% CI 84.5‐90.2) for BEACOPP. Two follow‐up periods were identified based on survival curves and hazard ratio (HR) over time. For the first 18 months, there was no difference. For the second period of ≥18 months, ABVD patients had a higher death risk (HRABVD vs BEACOPP = 1.59; 95% CI 1.09‐2.33). A Cox model stratified by trial and evaluating the effect of treatment and International Prognostic Index (IPI) score as fixed effects showed that both were statistically significant (treatment, P =.0185; IPI score, P =.0107). The 7‐year PFS was 71.1% (95% CI 67.1‐74.6) for ABVD vs 81.1% (95% CI 77.5‐84.2) for BEACOPP (P <.001). After ABVD, 25 secondary cancers (4.0%) were reported with no myelodysplasia (MDS)/acute myeloid leukemia (AML) compared to 36 (6.5%) after BEACOPP, which included 13 patients with MDS/AML. Following ABVD, 86 patients (13.8%) received ASCT vs 39 (6.4%) for BEACOPP. Conclusions: This analysis showed a slight improvement in OS for BEACOPP and confirmed a PFS benefit. Frontline use of BEACOPP instead of ABVD increased secondary leukemia incidence but halved the requirement for ASCT. [ABSTRACT FROM AUTHOR]

Summary: The treatment of low‐tumour burden follicular lymphoma (LTBFL) remains a challenge. Rituximab‐based strategies may be improved by adding chemotherapy. This Lymphoma Study Association multicentre phase II study assessed rituximab and bendamustine in 63 patients with untreated LTBFL who were aged over 60 years old and had a follicular lymphoma International Prognostic Index (FLIPI) score ≥2. Induction comprised 4 weekly cycles of rituximab 375 mg/m2 intravenously combined with 2 cycles of bendamustine 90 mg/m2 days 1–2 with a 28‐day interval, followed by twelve cycles of 375 mg/m2 rituximab maintenance therapy every 8 weeks. The primary endpoint was complete response (CR)/unconfirmed CR (CRu), at 12 weeks. Median age was 67·4 years and median FLIPI was 3. Ultimately, 18 patients (29%) had high tumour burden according to Groupe d'Etude des Lymphomes Folliculaires criteria. The 12‐week CR/CRu rate was 54·0% and the overall response rate was 93·7%. Surprisingly, 3 patients died during maintenance (2 sepsis, 1 neoplasm). Progression‐free survival was 85·4% at 24 months. In LTBFL patients with FLIPI ≥2, two cycles of rituximab and bendamustine result in a CR rate of 54·0%. However, the treatment‐related deaths observed do not allow this regimen to be recommended for LTBFL patients aged over 60 years. EudraCT: 2010‐020757‐14; ClinicalTrials.gov: NCT01313611.

Summary: Tandem stem cell transplantation (SCT) is an option for high‐risk relapsed/refractory Hodgkin Lymphoma (HL) patients. We evaluated the tolerance/efficacy of double autologous or autologous SCT (ASCT) followed by allogenic SCT (alloSCT) in 120 HL patients prospectively registered on a French nationwide database. Median age was 26 (14–56) years. Complete remission rate was 60%, including 33% after a single line, and another 27% after two or more salvage regimens. Partial response rate was 32%, and 8% suffered treatment failure. Overall, 115 (96%) patients underwent a first ASCT, and 73 (61%) had a tandem SCT, including alloSCT in 44 (60%) and ASCT in 29 (40%). The median follow‐up was 43 months (4.8–73.7 months). The two‐year progression‐free survival rate for the whole population and for patients receiving tandem transplant was 56% (95% confidence interval [CI]: 46–65%) and 71% (95% CI: 49–84%), respectively. Among tandem transplants, we observed 20 deaths (17%), 10 of which were transplant‐related (6 alloSCT and 4 ASCT). We suggest that tandem SCT is efficient in high‐risk relapsed/refractory HL patients, although transplant‐related mortality remains high. The benefit of tandem SCT should be balanced with the efficacy of Brentuximab vedotin‐based post‐transplant consolidative strategies in high‐risk relapsed/refractory HL patients.

The article discusses a study which examined the clinical and biological characteristics of patients with both myelodysplastic syndromes/acute myeloid leukaemia (MDS/AML) and lymphoma. Topics include the complications of cytotoxic chemotherapy (CT) and radiotherapy (RT), the occurrence of MDS/AML in patients with Hodgkin lymphoma (HL) or non-Hodgkin lymphoma (NHL), and the diagnosis of MDS/AML.

There is no standard of care in elderly classical Hodgkin lymphoma (cHL) patients. ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine), the standard chemotherapy for younger patients, is also used in elderly patients but little is known about toxicity and efficacy. We retrospectively analysed 147 patients aged 60 years and over treated with ABVD in three French haematological centres. Treatment regimen modification was applied in 56 patients for toxicity or HL progression. Bleomycin was removed or reduced in 53 patients, mainly for pulmonary toxicity. Neither initial characteristics nor treatment characteristics were found to correlate with lung toxicity. One hundred and seventeen patients achieved a complete remission, 6 a partial remission, 16 had refractory disease and 8 were non-evaluable. Five-year overall survival was estimated at 67%. With a median follow-up of 58 months, 51 patients died and 14% of deaths were related to lung toxicity. Our study confirms the efficacy of ABVD in elderly patients even if results are inferior to those obtained in younger patients with the same regimen. ABVD can be proposed as front-line chemotherapy in selected elderly cHL patients. The frequency of pulmonary events leads us to propose to either reduce the dose of bleomycin or to remove it from the regimen. [ABSTRACT FROM AUTHOR]

The article discusses the use of doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD) chemotherapy in the treatment of Hodgkin lymphoma (HL) patients. Topics discussed include investigation of positron emission tomography (PET) driven dose-reduction strategy in patients, oral administration of etoposide, and adjustment of chemotherapy intensity.

The article discusses the results of a retrospective cohort of patients with nodular lymphocyte predominant Hodgkin lymphoma (NLPHL), ineligible for radiation therapy, treated with the monoclonal antibody Rituximab and standard adriamycin, bleomycin, vinblastine, dacarbazine (ABVD). Topics covered include the effectivity and safety of combination drug therapy with Rituximab and ABVD, risk of pulmonary events, and Rituximab's use as a single agent in front-line therapy in advanced NLPHL.

The risk of developing Hodgkin lymphoma ( HL) is increased in immunodeficiencies or during the treatment of some autoimmune diseases. The development of new therapeutic agents has highlighted the risk of unusual lymphoid proliferations, particularly classical HL (c HL). We report the clinicopathological findings of 13 c HL arising in patients treated for a primary haematological malignancy. Eight patients had received an immunomodulator, protein tyrosine-kinase inhibitor or monoclonal antibody, which may have contributed to the c HL development. Most patients had disseminated disease with poor prognostic factors at cHL diagnosis. Despite the initial presentation, good outcomes were achieved with standard c HL chemotherapy.

Around 20% of Hodgkin lymphoma (HL) patients are refractory to first-line therapy with ABVD (adriamycin-bleomycin-vinblastine-dacarbazine) or relapse after complete remission. Salvage regimens frequently have delayed courses or require dose-reduction because of haemotoxicity. We evaluated the IVOx (ifosfamide-etoposide-oxaliplatin) salvage regimen in terms of response rate, toxicity and stem-cell mobilization. Thirty-four patients with relapsed/refractory HL after anthracycline-containing chemotherapy prospectively received IVOx, consisting of ifosfamide (1500 mg/m days 1-3), etoposide (150 mg/m days 1-3) and oxaliplatin (130 mg/m day 1). Patients <65 years old received high-dose therapy followed by autologous stem-cell transplantation (HDT-ASCT). Response was assessed by computed and positron-emission tomographies. Overall and complete response rates were 76% and 32%, respectively, after 2 cycles. Three episodes of febrile neutropenia occurred, and three patients required dose-reductions. Twenty-six patients underwent HDT-ASCT. With median follow-up at 5 years, the 5-year overall and event-free survival rates were 74% and 63%, respectively. IVOx is a well-tolerated outpatient regimen for relapsed HL, that does not hamper stem-cell mobilization, achieves good response rates and compares favourably with previously published salvage regimens.

The article evaluates the efficacy and safety of rituximab combined with intravenous fludarabine and mitoxantrone (R-FM) for patients with recurrent/refractory follicular non-Hodgkin lymphoma who had high tumor burden according to Groupe d'Etrude des Lymphomes Folliculaires (GELF). The results of the study revealed that the best overall response rate was achieved after four courses of R-FM, regardless of age, refractoriness to last previous therapy and score in Follicular Lymphoma International Prognostic Index (FLIPI).

The article focuses on a research about the long-term results of the registered patients and their rate of histologic transformation (HT) rate to diffuse large B-cell lymphoma (DLBCL). It states that 164 patients with nodular, lymphocyte-predominant Hodgkin lymphoma (NLPHL) served as subjects of the study. Findings show that there was no significant difference in the overall survival rate after HT of patients who underwent autologous stem cell transplantation (ASCT) and the others.

The article reports on the result of the study conducted to determine the efficacy and toxicity the combination between of bortezomib and rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in patients with B-cell lymphoma. The study includes 49 patients having B-cell lymphoma. Result shows that the combination was an effective regimen and produced an 84 percent complete response rate.

SGN-30, a chimeric anti-CD30 monoclonal antibody, has demonstrated potent preclinical antitumour activity in both Hodgkin lymphoma (HL) and anaplastic large cell lymphoma (ALCL). We conducted an open-label, Phase II study to determine the safety and objective response rate of SGN-30 in 79 patients with refractory/recurrent HL ( n = 38) or systemic ALCL ( n = 41). Each course of SGN-30 comprised 6 weekly intravenous infusions, followed by a 2-week treatment-free period. Patients had received a median of 3 (range 1–5) prior regimens of chemotherapy or systemic therapy. The initial 40 patients received 6 mg/kg weekly; the latter 39 patients received 12 mg/kg weekly. In the ALCL group, two patients achieved a complete response and five additional patients achieved a partial response, with response durations ranging from 27 to 1460+ d. No objective responses were observed in the HL group; however, 11 patients (29%) had stable disease (duration 62–242 days). Although adverse events were common, most were mild or moderate, and no specific pattern of adverse events was observed in either disease group. These results demonstrate that weekly administration of SGN-30 is safe, with modest clinical activity in patients with ALCL. [ABSTRACT FROM AUTHOR]

Despite a high curability rate, some patients with Hodgkin lymphoma (HL) fail to respond to, or relapse after, primary conventional treatment. This review aims to identify prognostic factors at relapse and guidelines for treatment in relapsed HL. Patients with relapsed HL should be identified according to their prognostic factors at relapse (duration of remission and extranodal disease or stage). This enables relapsing patients to be separated in to three different prognostic groups; primary refractory patients should be included in the unfavourable group because of their poor prognosis. All relapsed HL should receive second-line chemotherapy and the response to this chemotherapy is crucial for the outcome. Benefit of autologous stem-cell transplantation (ASCT) has been shown in a large randomized study and, although is often proposed in relapsed HL, it may be not necessary in the rare group of patients with stage I/II and late relapse who can receive additional radiotherapy after response to chemotherapy. Patients with intermediate and unfavourable relapse should receive high-dose chemotherapy and ASCT when chemosensitive; the first goal is to achieve this chemosensitivity. For patients in the unfavourable group, including refractory patients, the role of tandem HDT or allogeneic SCT will be discussed and should be proposed for patients not in complete remission at the time of HDT.

Background: In patients with lymphoma who had a poor prognosis, pretransplantation 18-fluorodeoxyglucose (FDG)-positron-emission tomography (PET) was important for the evaluation of response and outcome. However, little is known about the correlation of FDG-PET with post-transplantation PET. The current study was designed to ascertain whether positive pretransplantation PET images are modified by the conditioning regimen. Methods: Sixty consecutive patients who had achieved remission and underwent consolidation by autologous stem cell transplantation (ASCT) had PET images obtained before ASCT (after 3 or 4 chemotherapy cycles) and 100 days after ASCT. The correlation was explored between the presence of abnormal 18-FDG uptake (PET positive) or its absence (PET negative) and patient outcomes. Results: Before ASCT, 31 patients achieved complete remission (CR), and 23 patients achieved uncertain CR. Before ASCT, 44 patients (75%) were had negative PET images; and, after ASCT, 48 patients (80%) had negative PET images. One year after ASCT, the estimated event-free survival (EFS) rate was 80% in patients who had negative pre-ASCT PET images compared with 43% in patients who had positive pre-ASCT PET images (P = .0002). The EFS rate was 81% in patients who had negative post-ASCT PET images compared with 25% in patients who had negative post-ASCT PET images (P < .0001). In multivariate analysis, only the results for pre- and post-ASCT PET images retained prognostic value, with relative risks of failure estimated at 4.9 and 11.9, respectively. Conclusions: A positive pre-ASCT PET image indicated a high risk of ASCT failure, which was increased by a positive post-ASCT PET image. For patients with lymphoma who have positive pre-ASCT PET images, more investigations using new treatment approaches will be required. For patients who have negative pre-ASCT PET images, obtaining post-ASCT PET images does not seem to be mandatory. [ABSTRACT FROM AUTHOR]

The influence of bone marrow biopsy (BMB) histology on prognosis and management of follicular lymphomas (FL) remains controversial. A total of 390 patients with grade 1 or 2 FL were prospectively included in the multicentric Groupe d'Etude des Lymphomes Folliculaires trial and their BMB reviewed in order (i) to quantify the ratio of lymphomatous foci (LFo) area to that of BMB size (LFo/BMB), (ii) to determine the BMB patterns for a practical grading of marrow infiltration, (iii) to assess the intra- and inter-observer reproducibility of this grading and (iv) to analyse this grading on event-free (EFS) and overall survival (OS), using univariate and multivariate analyses. A total of 267 patients (68%) had BMB involvement, with inter- and intra-observer reproducibility for classifying the patterns of involvement of 91 and 96%, respectively. Uni- and multivariate analyses demonstrated the adverse influence of (i) a ratio of LFo/BMB ≥0·1, i.e. three or four nodules/medullary space or ≥1 nodule + foci of diffuse involvement on EFS ( P = 0·03) and (ii) two different histological patterns in the same BMB on EFS ( P = 0·004) and OS ( P = 0·001). This latter finding was only significant in patients with a high tumour burden and remained significant in multivariate analysis. These results indicate that BMB histology can predict survival of FL patients with a high tumour burden, and may help in defining their treatment. [ABSTRACT FROM AUTHOR]

Abstract Background A role for hepatitis C virus (HCV) infection has been suggested in the pathogenesis of non-Hodgkin lymphomas (NHL). Aim To evaluate the characteristics of cutaneous lymphomas occurring in HCV-infected patients, and to investigate the hypothesis of a direct infection of malignant cells. Methods Three patients showing a positive serology for HCV and a cutaneous lymphoma were studied. Analysis of HCV replication was performed using reverse transcriptase–polymerase chain reaction. The presence of HCV RNA was also assessed in biopsies from lesional skin and in a lymph node in one case. Genotype characterization was carried out on the basis of LiPA genotyping assays using viral genomic amplification products. Results Cutaneous NHL occurred in patients with chronic and replicative HCV infection, and exhibited a B-cell phenotype (one diffuse large B-cell lymphoma, one follicular lymphoma, and one marginal zone B-cell lymphoma). All patients were male; two of them were former intravenous drug abusers, while the HCV contamination route was unknown in the third. The search for HCV RNA in the skin and in lymph nodes yielded negative results. HCV genotypes were 1b in two cases and 3a in one case. Conclusion These results show that a subset of B-cell cutaneous NHL is associated with a replicative HCV infection and suggest that HCV is not involved in lymphomagenesis through a direct infection of malignant cells. The ability of HCV to trigger a chronic B-cell lymphoproliferation could represent another mechanism, while a fortuitous association cannot be excluded. [ABSTRACT FROM AUTHOR]

The article focuses on a retrospective study carried out on 45 patients between 2009 and 2012 regarding investigation of the activity of the antibody-drug conjugate brentuximab vedotin (BV) in heavily treated Hodgkin Lymphoma (HL) and anaplastic large-cell lymphoma (ALCL). The study confirms the efficacy of BV in the setting of relapsed or refractory lymphoma and proves the effectiveness of BV in this group of patients. Further presented are various tables regarding the study.

The article discusses a study on pegylated liposomal doxorubicin (PLD) treatment for Hodgkin lymphoma (HL) patients relapsing after stem cell transplation and high dose therapy. It informs that the study included mediastinal radiation therapy, supra-diaphragmatic radiotherapy, and standard chemotherapy regimens. The study found that patients can be treated for long periods with low-toxicity monotherapy such as vinblastine, brentuximab vedotin, and panobinostat.
