To compare doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD) versus bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) versus ...cyclophosphamide, lomustine, vindesine, melphalan, prednisone, epidoxirubicin, vincristine, procarbazine, vinblastine, and bleomycin (COPPEBVCAD; CEC) for advanced Hodgkin's lymphoma (HL).
Three hundred seven patients with advanced HL (stage IIB, III, and IV) were randomly assigned to receive six courses of ABVD, four escalated plus two standard courses of BEACOPP, or six courses of CEC, plus a limited radiation therapy program.
After a median follow-up of 41 months, BEACOPP resulted in a superior progression-free survival (PFS), with a significant reduction in risk of progression (hazard ratio HR = 0.50) compared with ABVD. No differences between BEACOPP and CEC, or CEC and ABVD were observed. The 5-year PFS was 68% (95% CI, 56% to 78%), 81% (95% CI, 70% to 89%), and 78% (95% CI, 68% to 86%), for ABVD, BEACOPP, and CEC, respectively (BEACOPP v ABVD, P = .038; CEC v ABVD and BEACOPP v CEC, P = not significant NS). The 5-year overall survival was 84% (95% CI, 69% to 92%), 92% (95% CI, 84% to 96%), and 91% (95% CI, 81% to 96%) for ABVD, BEACOPP, and CEC, respectively (P = NS). BEACOPP and CEC resulted in higher rates of grade 3-4 neutropenia than ABVD (P = .016); BEACOPP was associated with higher rates of severe infections than ABVD and CEC (P = .003).
As adopted in this study BEACOPP is associated with a significantly improved PFS compared with ABVD, with a predictable higher acute toxicity.
Purpose
Prevention of chemotherapy-induced nausea and vomiting (CINV) is particularly challenging for patients receiving highly emetogenic preparative regimens before autologous stem cell ...transplantation (ASCT) due to the daily and continuous emetogenic stimulus of the multiple day chemotherapy. While studies have shown effective prevention of CINV during the conditioning phase with NK
1
receptor antagonist (NK
1
RA)-containing regimens, there have been no studies evaluating antiemetic use during chemomobilization prior to ASCT.
Methods
This multicenter, open-label, phase IIa study evaluated the efficacy of every-other-day dosing of NEPA administered during chemomobilization in patients with relapsed-refractory aggressive non-Hodgkin’s lymphoma. Eighty-one patients participated.
Results
Response rates were 77.8% for complete response (no emesis and no rescue use), 72.8% for complete control (complete response and no more than mild nausea), 86.4% for no emesis, and 82.7% for no rescue use during the overall phase (duration of chemomobilization through 48 h after). NEPA was well tolerated with no treatment-related adverse events reported.
Conclusion
NEPA, administered with a simplified every-other-day schedule, show to be very effective in preventing CINV in patients at high risk of CINV undergoing to chemomobilization of hematopoietic stem cells prior to ASCT.
Background
Compared with older 5‐HT3 receptor antagonists, palonosetron requires fewer drug administrations to prevent chemotherapy‐induced nausea and vomiting (CINV) following multiple‐day ...chemotherapy. We conducted a phase II multicenter study comparing palonosetron plus aprepitant to palonosetron alone in patients undergoing a range of induction chemotherapy regimens for acute myeloid leukemia (AML).
Methods
Patients were randomized to palonosetron (0.25 mg) every other day until the last dose of chemotherapy alone or with aprepitant on days 1‐3. Patients mainly received an anthracycline on days 1‐3 plus cytarabine administered for 5‐10 days. The primary end point was complete response (CR; no emesis and no rescue medication) over the whole study period (days of chemotherapy plus two additional days). Unplanned analysis of time to anti‐emetic treatment failure (TTF) was also performed.
Results
Of the 134 patients enrolled in the study, 130 were evaluable: 68 subjects received palonosetron plus aprepitant and 62 received palonosetron alone. Although the primary end point of CR was similar between the treatment arms (72% vs 69%; P = .55), a higher proportion of patients treated with palonosetron plus aprepitant were free from nausea during the whole study period (43% vs 27%; P = .03). There was also a significant difference in favor of the two‐drug regimens in TTF (median: 5 days vs 3 days; P = .03).
Conclusions
The study suggests that every‐other‐day palonosetron plus 3‐day aprepitant can add clinical benefit to the control of CINV caused by multiple‐day, corticosteroid‐free chemotherapy for AML. In this challenging setting of CINV, further investigations of palonosetron in combination with aprepitant administered with an expanded schedule are warranted.
ClinicalTrial.gov identifier: NCT02205164.
In this randomized study on acute myeloid leukemia patients treated with multiple‐day induction chemotherapy, the authors investigated the efficacy of a simplified antiemetic prophylaxis consisting of every‐other‐day palonosetron plus 3‐day aprepitant compared to palonosetron alone. Although similar rates of complete response were observed, the combination regimen significantly improved control of nausea in this challenging setting of chemotherapy‐induced nausea and vomiting.
Occupational exposure is known to play a role in the aetiology of lymphomas. The aim of the present work was to explore the occupational risk of the major B-cell lymphoma subtypes using a ...case-control study design.
From 2009 to 2014, we recruited 158 lymphoma cases and 76 controls in the provinces of Bari and Taranto (Apulia, Southern Italy). A retrospective assessment of occupational exposure based on complete work histories and the Carcinogen Exposure (CAREX) job-exposure matrix was performed.
After adjusting for major confounding factors, farmers showed an increased risk of diffuse large B-cell lymphoma (DLBCL) odds ratio (OR) = 10.9 (2.3-51.6) and multiple myeloma (MM) OR = 16.5 (1.4-195.7); exposure to the fungicide Captafol was significantly associated with risk of non-Hodgkin lymphoma (NHL) OR = 2.6 (1.1-8.2), particularly with the risk of DLBCL OR = 5.3 (1.6-17.3).
Agricultural activity seems to be a risk factor for developing lymphoma subtypes, particularly DLBCL, in the provinces of Bari and Taranto (Apulia Region, Southern Italy). Exposure to the pesticides Captafol, Paraquat and Radon might be implicated.

To evaluate the role of early intensification with high-dose therapy (HDT) and autologous stem-cell transplantation (ASCT) as front-line chemotherapy for patients with high-risk, histologically ...aggressive non-Hodgkin's lymphoma (NHL).
We planned a multicenter, randomized trial to compare a conventional chemotherapy regimen of methotrexate with leucovorin rescue, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin (MACOP-B; arm A) with an abbreviated regimen of MACOP-B (8 weeks) followed by HDT and ASCT (arm B) for intermediate-high-risk/high-risk patients (according to the age-adjusted International Prognostic Index). From September 1994 to April 1998, 150 patients with aggressive lymphoma were enrolled onto the trial. Seventy-five patients were randomly assigned to arm A and 75 patients were randomly assigned to arm B. In both arms, involved-field radiation therapy (36 Gy) was delivered to the site of bulky disease.
The rate of complete response was 68% in arm A and 76% in arm B (P = not significant NS). Three toxic deaths (4%) occurred in arm B and one (1%) occurred in arm A (P = NS). In arm B, 30 patients (40%) did not undergo HDT and ASCT. According to the intention-to-treat analysis at a median follow-up of 24 months, 5-year overall survival probability in arms A and B was 65% and 64% (P =.95), 5-year progression-free survival was 49% and 61% (P =.21), and 5-year relapse-free survival was 65% and 77% (P =.22), respectively.
Abbreviated chemotherapy followed by intensification with HDT-ASCT is not superior to conventional chemotherapy in patients with high-risk, aggressive NHL. Additional randomized trials will clarify whether HDT-ASCT as front-line therapy after a complete course of conventional chemotherapy improves survival in this group of patients.
We designed a trial in which postremission therapy of young patients with de novo acute myeloid leukemia (AML) was decided combining cytogenetics/genetics and postconsolidation levels of minimal ...residual disease (MRD). After induction and consolidation, favorable-risk patients (FR) were to receive autologous stem cell transplant (AuSCT) and poor-risk patients (PR) allogeneic stem cell transplant (AlloSCT). Intermediate-risk patients (IR) were to receive AuSCT or AlloSCT depending on the postconsolidation levels of MRD. Three hundred sixty-one of 500 patients (72%) achieved a complete remission, 342/361 completed the consolidation phase and were treatment allocated: 165 (48%) to AlloSCT (122 PR, 43 IR MRD-positive) plus 23 rescued after salvage therapy, for a total of 188 candidates; 150 (44%) to AuSCT (115 FR, 35 IR MRD-negative) plus 27 IR patients (8%) with no leukemia-associated phenotype, for a total of 177 candidates. Overall, 110/177 (62%) and 130/188 (71%) AuSCT or AlloSCT candidates received it, respectively. Two-year overall (OS) and disease-free survival (DFS) of the whole series was 56% and 54%, respectively. Two-year OS and DFS were 74% and 61% in the FR category, 42% and 45% in the PR category, 79% and 61% in the IR MRD-negative category, and 70% and 67% in the IR MRD-positive category. In conclusion, AuSCT may still have a role in FR and IR MRD-negative categories. In the IR MRD-positive category, AlloSCT prolongs OS and DFS to equal those of the FR category. Using all the available sources of stem cells, AlloSCT was delivered to 71% of the candidates.This trial was registered at www.clinicaltrials.gov as #NCT01452646 and EudraCT as #2010-023809-36.
•A risk-adapted, MRD-driven transplant strategy is a feasible approach for the treatment of younger adults with AML.•Pretransplant MRD positivity should not contraindicate delivery of an allogeneic stem cell transplant.

Summary
Idelalisib, a reversible inhibitor of PI3Kδ (phosphoinositide‐3 kinase delta), showed remarkable activity in the phase II DELTA trial, leading to its approval by the European Medicines Agency ...(EMA) in patients with relapsed/refractory (R/R) follicular lymphoma (FL). However, real‐life data on idelalisib are scarce. We treated 55 double‐refractory FL patients with idelalisib in a real‐life setting. With a median exposure to idelalisib of 10 months (range 1–43), overall response rate was 73%, the highest ever reported. Non‐haematological toxicities were mild and manageable. At 12 months, 80% of patients were alive, and 72% disease‐free. The efficacy and safety of idelalisib was confirmed in a real‐life setting.
A first comparative trial of fludarabine (FLU) alone versus FLU plus idarubicin (FLU-ID) for indolent or mantle-cell lymphomas.
From September 1995 to July 1998, 199 patients aged 25 to 65 years ...(median, 54 years) with newly diagnosed stages II to IV indolent or mantle-cell lymphomas (standard risk according to the International Prognostic Index) were enrolled onto a multicenter, 1:1 randomized study. Of the 199 patients who were able to be assessed, 101 were assigned to the FLU group (six monthly cycles of FLU 25 mg/m(2)/d on days 1 through 5) and 98 to the FLU-ID group (six monthly cycles of FLU 25 mg/m(2)/d on days 1 through 3 and idarubicin 12 mg/m(2) on day 1).
In the FLU group, complete response (CR) and partial response rates were 47% and 37%, respectively, whereas in the FLU-ID group, they were 39% and 42%, respectively. In-depth analysis of the CR rate with respect to histologic type showed that FLU seemed to be superior to FLU-ID in treating follicular lymphomas (60% v 40%, respectively), whereas FLU-ID seemed to be more effective than FLU in treating nonfollicular lymphomas (small lymphocytic, 43% v 29%, respectively; immunocytoma, 38% v 23%, respectively; P = not significant), excluding the mantle-cell subset (in which there was no difference between the two groups). No striking differences were observed between the two protocols in terms of overall response or toxicity, which was generally mild. However, with a median follow-up of 19 months, only 29 patients (62%) who received FLU alone have maintained their initial CR, compared with 32 (84%) of those who received FLU-ID therapy (P =.021).
Although the FLU-ID regimen may not significantly improve the induction of CR in most indolent-lymphoma patients, our preliminary data do suggest that, with respect to FLU alone, it may be capable of conferring a longer-lasting CR and that it might be superior in terms of CR rate in small lymphocytic and immunocytoma subtypes.
