Advanced Hodgkin lymphoma in the East of England: a 10-year comparative analysis of outcomes for real-world patients treated with ABVD or escalated-BEACOPP, aged less than 60 years, compared with 5-year extended follow-up from the RATHL trial.

Treatment with ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) or escalated(e)-BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisolone) remains the international standard of care for advanced-stage classical Hodgkin lymphoma (HL). We performed a retrospective, multicentre analysis of 221 non-trial ("real-world") patients, aged 16-59 years, diagnosed with advanced-stage HL in the Anglia Cancer Network between 2004 and 2014, treated with ABVD or eBEACOPP, and compared outcomes with 1088 patients in the Response-Adjusted Therapy for Advanced Hodgkin Lymphoma (RATHL) trial, aged 18-59 years, with median follow-up of 87.0 and 69.5 months, respectively. Real-world ABVD patients (n=177) had highly similar 5-year progression-free survival (PFS) and overall survival (OS) compared with RATHL (PFS 79.2% vs 81.4%; OS 92.9% vs 95.2%), despite interim positron-emission tomography-computed tomography (PET/CT)-guided dose-escalation being predominantly restricted to trial patients. Real-world eBEACOPP patients (n=44) had superior PFS (95.5%) compared with real-world ABVD (HR 0.20, p=0.027) and RATHL (HR 0.21, p=0.015), and superior OS for higher-risk (international prognostic score ≥3 [IPS 3+]) patients compared with real-world IPS 3+ ABVD (100% vs 84.5%, p=0.045), but not IPS 3+ RATHL patients. Our data support a PFS, but not OS, advantage for patients with advanced-stage HL treated with eBEACOPP compared with ABVD and suggest higher-risk patients may benefit disproportionately from more intensive therapy. However, increased access to effective salvage therapies might minimise any OS benefit from reduced relapse rates after frontline therapy

Treatment and outcome patterns in European patients with Waldenström’s macroglobulinaemia: a large, observational, retrospective chart review

Background: Treatment options for Waldenström's macroglobulinaemia are heterogeneous, and no well established treatment standards exist. Although guidelines from the Eighth International Workshop on Waldenstrom's Macroglobulinemia were published in 2016, inconsistent awareness and budget constraints have prevented their widespread implementation, and real-life treatment patterns might differ across health-care systems. We aimed to generate information about treatment and outcome patterns for patients with Waldenström's macroglobulinaemia outside of clinical trials. Methods: In this large, observational, retrospective chart review, academic and community physicians in ten European countries were invited to retrospectively complete electronic records for patients with symptomatic Waldenström's macroglobulinaemia who had begun treatment after Jan 1, 2000, and before Jan 1, 2014, and had available clinical and biological data. The primary endpoints were reasons for treatment initiation, treatment choices, progression-free survival, and overall survival. We assessed the variables that affected choice of front-line therapy, progression-free survival, and overall survival in multivariate analyses. Findings: Electronic records were reviewed for 454 eligible patients. The most frequent reasons for starting front-line treatment were anaemia (in 328 [72%] patients) and constitutional symptoms (in 264 [58%] patients). Choice of therapy varied between front-line, second-line, and third-line approaches; age; and type of institution. In the front-line setting, 193 (43%) of 454 patients received monotherapy, 164 (36%) received chemoimmunotherapy, and 95 (21%) received other combination regimens (data on front-line treatment were missing for one patient, and another patient received only steroids). After front-line treatment, median progression-free survival was 29 months (95% CI 25–31), median overall survival was not reached (not reached–not reached), and 10-year overall survival was 69% (62–74). In multivariate analyses, patients who were high risk according to the International Prognostic Scoring System for Waldenström Macroglobulinemia had significantly worse progression-free survival and overall survival than did those who were low risk. Additionally, progression-free survival was shortened in patients treated with monotherapy compared with those treated with chemoimmunotherapy or other combination therapies and in those treated at an academic institution compared with those treated in the community. Constitutional symptoms (excluding fatigue) were associated with worsened overall survival. Interpretation: This large observational dataset should inform and help set guidelines, and improve understanding of treatment practices and outcomes, for European patients with Waldenström's macroglobulinaemia.

Managing relapsed refractory lymphoma with palliative oral chemotherapy: A multicentre retrospective study.

PEP-C (prednisolone, etoposide, procarbazine and cyclophosphamide) is an orally administered daily chemotherapy regimen used with palliative intent in relapsed refractory lymphoma. To our knowledge, no data on PEP-C have been reported since the original group described the regimen. Here we present a multicentre retrospective cohort reporting our use of PEP-C in 92 patients over an 8-year period. We find that even heavily pretreated lymphoma can respond to PEP-C, particularly low-grade lymphoma (including mantle cell) and lymphoma that was sensitive to the previous line of systemic therapy (chemosensitive). These characteristics may help in the selection of patients likely to derive benefit. The median overall survival of patients with chemosensitive lymphoma treated with PEP-C is 217 days. Within the limitations of a retrospective cohort, we find that PEP-C is well tolerated: the most common toxicity leading to discontinuation is marrow suppression. We suggest that PEP-C should be considered for patients with relapsed refractory lymphoma in two settings: first, where there is no licensed alternative; and second, where the licensed alternative is an intravenous drug and the patient would prefer to choose an oral chemotherapy option

Results of a UK real world study of polatuzumab vedotin, bendamustine, and rituximab for relapsed/refractory large B-cell lymphoma.

The addition of polatuzumab vedotin to bendamustine and rituximab (Pola-BR) has been shown to improve overall survival (OS) in stem cell transplant (SCT)-ineligible patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL). It is also increasingly used as bridging to CAR T-cell therapy (CAR-T). We retrospectively analysed the efficacy of Pola-BR in 133 patients at 28 UK institutions. Treatment intent was bridging to CAR-T for N=40, re-induction with planned SCT for N=13 and stand-alone treatment for N=78. The overall response rate (ORR) was 57.0% (complete response (CR) 32.8%). After median 7.7 months follow-up, median PFS and OS were 4.8 months and 8.2 months respectively. For stand-alone treatment shortened PFS was associated with bulk disease (>7.5cm) (HR 2.32 (95% CI 1.23-4.38), p=0.009), >1 prior treatment (HR 2.17 (95% CI 1.19-3.95), p=0.01) and refractoriness to the last treatment (HR 3.48 (95% CI 1.79-6.76), p<0.001). For CAR-T bridging the ORR was 42.1% (CR 18.4%) and for treatment after CAR-T failure the ORR was 43.8% (CR 18.8%). These data demonstrate efficacy for Pola-BR as a treatment for SCT-ineligible patients with R/R DLBCL, help to delineate which patients may benefit most, and provide preliminary evidence of efficacy as bridging to CAR-T and after CAR-T failure
