Prognostic Value of Baseline Tumor Burden and Tumor Dissemination Extracted From 18 F-FDG PET/CT in a Cohort of Adult Patients With Early or Advanced Hodgkin Lymphoma.

PURPOSE: We aimed to assess the prognostic value of baseline tumor burden and dissemination parameters extracted from 18 F-FDG PET/CT in patients with early or advanced Hodgkin lymphoma (HL) treated with ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) or escalated BEACOPP (increased bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone). PATIENTS AND METHODS: Patients aged ≥18 years with classical Hodgkin lymphoma were retrospectively included. Progression-free survival (PFS) analysis of dichotomized clinicobiological and PET/CT parameters (SUV max , TMTV, TLG, D max , and D bulk ) was performed. Optimal cutoff values for quantitative metrics were defined as the values maximizing the Youden index from receiver operating characteristic analysis. PFS rates were estimated with Kaplan-Meier curves, and the log-rank test was used to assess statistical significance. Hazard ratios were calculated using Cox proportional hazards models. RESULTS: With a median age of 32 years, 166 patients were enrolled. A total of 111 patients had ABVD or ABVD-like treatment with or without radiotherapy and 55 patients with escalated BEACOPP treatment. The median follow-up was 55 months. Only International Prognostic Score (IPS >1), TMTV >107 cm 3 , and TLG >1628 were found to be significant prognostic factors for PFS on univariate analysis. Multivariate analysis revealed that IPS and TLG were independently prognostic and, combined, identified 4 risk groups ( P < 0.001): low (low TLG and low IPS; 4-year PFS, 95%), intermediate-low (high IPS and low TLG; 4-year PFS, 79%), intermediate-high (low IPS and high TLG; 4-year PFS, 78%), and high (high TLG and high IPS; 4-year PFS, 71%). CONCLUSIONS: Combining baseline TLG with IPS could improve PFS prediction.

[The history of Hodgkin lymphoma]. / Historique du lymphome de Hodgkin.

THE HISTORY OF HODGKIN LYMPHOMA. Hodgkin lymphoma was initially considered to be caused by infectious agents. The Hodgkin and Reed-Sternberg tumor cells are derived from mature B cells and transforming events were identified. Staging laparotomy has been discontinued for clinical evaluation with the progress of medical imaging. For seven decades, clinical trials have allowed to define risk factors, to improve standard treatments with the optimal use of chemotherapy and radiotherapy. A risk adapted strategy and early response to chemotherapy are mandatory to reduce long-term consequences of treatment.

HISTORIQUE DU LYMPHOME DE HODGKIN. Une origine infectieuse du lymphome de Hodgkin a été initialement suspectée. L'origine des cellules tumorales, les mécanismes oncogéniques permettant leur survie et leur prolifération sont de connaissance plus récente. Après l'abandon de la laparotomie exploratrice, les progrès de l'imagerie médicale ont été continus. Pendant sept décennies, les essais cliniques ont permis de définir les facteurs de risque, d'améliorer les traitements de référence avec une utilisation optimale de la chimiothérapie et de la radiothérapie. La stratégie adaptée au risque et à la réponse précoce à la chimiothérapie est nécessaire pour limiter les conséquences tardives des traitements.

Work and education interruption in long-term Hodgkin lymphoma survivors: an analysis among patients from nine EORTC-LYSA trials.

BACKGROUND: Disease-specific studies on the impact of Hodgkin lymphoma (HL) on education or work interruption and resumption are lacking. MATERIAL AND METHODS: In a cross-sectional study conducted among long-term HL survivors enrolled from 1964 to 2004 in nine randomised EORTC-LYSA trials, the interruption and resumption of education/work was investigated. Survivors alive 5-44 years after diagnosis who were studying or working at time of diagnosis were included (n = 1646). Patient and treatment characteristics were obtained from trial records. Education and work outcomes were collected using the Life Situation Questionnaire. Logistic regression was used to model education or work interruption; Cox regression was used to study resumption rates. RESULTS: Among survivors studying at time of diagnosis (n = 323), 52% (95% CI: 46-57%) interrupted their education; however, it was resumed within 24 months by 92% (95% CI: 87-96%). The probability of interruption decreased with time: the more recent the treatment era, the lower the risk (OR 0.70 per 10 years, 95% CI: 0.49-1.01). Treatment with radiotherapy (yes vs. no) was associated with a higher education resumption rate (HR 2.01, 95% CI 1.07-3.78) whereas age, sex, stage, radiotherapy field and chemotherapy were not.Among survivors working at time of diagnosis (n = 1323), 77% (95% CI: 75-79%) interrupted their work. However, it was resumed within 24 months by 86% (95% CI: 84%-88%). Women were more likely to interrupt their work as compared to men (OR 1.90, 95% CI: 1.44-2.51) and, when interrupted, less likely to resume work (HR 0.70, 95% CI: 0.61-0.80). Survivors with a higher educational level were less likely to interrupt their work (OR 0.68 for university vs. no high school, 95% CI: 0.46-1.03); and when interrupted, more likely to resume work (HR 1.50 for university vs. no high school, 95% CI: 1.21-1.86). Increasing age was also associated with lower resumption rates (HR 0.62 for age ≥50 vs. 18-29 years, 95% CI: 0.41-0.94). CONCLUSION: An interruption in education/work was common among long-term HL survivors. However, most of the survivors who interrupted their studies or work had resumed their activities within 24 months. In this study, no associations between survivors' characteristics and failure to resume education were observed. Female sex, age ≥50 years, and a lower level of education were found to be associated with not resuming work after treatment for HL.

Dissemination patterns of Hodgkin lymphoma using a probability network model based on [18F]-FDG PET/CT.

PURPOSE: The preferred hypothesis for the dissemination patterns of Hodgkin lymphoma (HL) is the contiguity hypothesis. However, this hypothesis is based on studies performed before the advent of [18F]-FDG PET/CT which is now the established reference for HL staging. This study aims to extract the dissemination patterns of HL using [18F]-FDG PET/CT and a probability network model. METHODS: We retrospectively analyzed [18F]-FDG PET/CT performed for initial staging of patients with classical HL. The HL involvement status (presence of absence) was reported for 19 supra- and infra-diaphragmatic lymph node regions and 4 extranodal regions (lung, spleen, liver, and osteo- medullary). The analysis of HL dissemination was carried out using HL involvement status for all regions through 3 distinct methods: comparison of nearby lymph node regions, correlation assessment between all regions and relationship strength between all regions using Ising network model. RESULTS: A total of 196 patients were included. Our results showed strong relationships between nearby involved lymph node regions (for example between the left pelvic and the abdominal lymph node regions (relationship strength = 0.980)) and between more distant regions (for example between right and left axillary lymph node regions (strength = 0.714)). Furthermore, involvement of the infra-diaphragmatic lymph node regions was significantly correlated with Ann Arbor stage IV (phi = 0.56, p < 0.001). CONCLUSION: This study confirms the hypothesis of lymphatic dissemination of HL in a contiguous mode, with additional links between more distant regions. These predictable dissemination patterns could be useful for the initial staging assessment of patients with HL using [18F]-FDG PET/CT.

Employment situation among long-term Hodgkin lymphoma survivors in Europe: an analysis of patients from nine consecutive EORTC-LYSA trials.

PURPOSE: Little is known about the employment situation of long-term Hodgkin lymphoma (HL) survivors despite their young age at diagnosis and the favorable prognosis of the disease. In this cross-sectional study, we aim to describe the employment situation in a cohort of long-term HL survivors compared to the general population and investigate the associations with disease characteristics and treatment exposure. METHODS: HL survivors > 25 years (n = 1961) were matched 1:25 to controls (n = 49,025) from the European Union Labour Force Survey. Individual treatment information was obtained from trial records. Employment and socio-demographic characteristics were collected using the Life Situation Questionnaire. Logistic regression models were used to estimate associations between disease and treatment characteristics with employment status and work-related attitudes. RESULTS: At employment assessment, 69.7% of survivors (95% CI: 67.6-71.7%) were working; of these, 68.9% (95% CI: 66.3-71.3%) worked full-time, a figure comparable to that of controls (p value 0.17). The risk of not working was associated with increasing age at diagnosis, increasing age at survey, female sex, lower educational level, and relapse history. Of those who were at work during treatment, 16.8% (95% CI: 14.5-19.3%) stated their income had subsequently decreased, which was attributed to their HL by 65.4% (95% CI: 57.5-72.8). Among those not at work, 25.1% (95% CI: 20.7-29.8) survivors were disabled compared to only 14.5% (95% CI: 13.8-15.3%) of controls. CONCLUSIONS: In this cohort of HL survivors, employment status was comparable to that of the general population. However, increasing age at follow-up, female sex, lower educational level, and relapse history are risk factors for unemployment, a perceived decrease in income, and disability. IMPLICATIONS FOR CANCER SURVIVORS: To further improve follow-up care, special attention should be paid to these vulnerable subgroups.

Attenuated cytarabine, etoposide, dexamethasone plus rituximab (R-Mini-CYVE) regimen for patients with relapsed or refractory B-cell non-Hodgkin's lymphoma not eligible for intensive chemotherapy.

OBJECTIVES: To evaluate the efficacy and tolerability of an attenuated immunochemotherapy regimen based on cytarabine, etoposide and dexamethasone plus rituximab (R-mini-CYVE) in patients with relapsed or refractory B-cell non-Hodgkin's lymphoma (NHL). METHODS: We included pretreated adult patients with B-cell NHL who were ineligible for high-dose immunochemotherapy (HDT). Cytarabine and etoposide were given at four different dose levels, depending on the patient's frailty. Up to 8 cycles were administered. RESULTS: Between 2013 and 2019, 56 patients with diffuse large B-cell lymphoma (n = 45, 80%) and indolent B-cell lymphoma (n = 11, 20%) were included. Median age was 75 (range: 36-88). Nineteen patients (35%) had a performance status ≥2. Patients received a median of 4 cycles of R-mini-CYVE. The objective response and the complete response rates were 50% and 33%, respectively. Median progression-free survival and overall survival times were 5.7 (95% CI: 0.5-10.9) and 14.7 (95% CI: 3.5-25.9) months, respectively. Grade ≥3 anaemia, thrombocytopenia and neutropenia occurred in 44%, 55% and 60% of the patients, respectively. The most frequent non-haematological grade ≥3 adverse events were sepsis (21%), fatigue (13%) and cytarabine-related neurotoxicity (5%). CONCLUSION: R-mini-CYVE demonstrated a meaningful antitumour efficacy and an acceptable safety profile in patients with relapsed/refractory B-cell NHL who were ineligible for HDT.

Repeated courses of low-dose 2 × 2 Gy radiation therapy in patients with indolent B-cell non-Hodgkin lymphomas.

PURPOSE: In patients with indolent B-cell non-Hodgkin's lymphoma (B-NHL), one course of low-dose radiotherapy (LD-RT) 2 × 2 Gy is emerging as new option of therapy in palliative setting. Efficacy of LD-RT when repeated remains to be determinate. This study aims to assess the efficacy of repeated LD-RT given in patients with indolent B-NHL. MATERIALS AND METHODS: All consecutive adult patients who received two or more courses of LD-RT 2 × 2 Gy for indolent B-NHL at Gustave Roussy institution, during the period 1990-2015 were retrospectively investigated. RESULTS: Thirty-three patients received two or more courses of LD-RT for indolent B-NHL during the study period. The median age was 57 (range 37-80) years, histological types were distributed among follicular lymphoma (n = 24 pts; 73%), marginal-zone lymphoma (n = 6 pts; 18%), and primary cutaneous follicle center lymphoma (n = 3 pts; 9%). The median number of low-dose radiation therapy courses given per patients was 2 (range 2-6). The overall response rates following the first and the second course of LD-RT were 96% and 88%, respectively (P = .31). The 1- and 2-years local control rates following the first courses of LD-RT were 94% (CI 95: 86-100) and 94% (CI 95: 86-98); and were 91% (CI 95: 82-100) and 88% (CI 95: 77-100) following the second course of LD-RT (P = .39). CONCLUSION: The repeated courses of LD-RT offered similar efficacy compare with the first course in patients with indolent B-NHL. LD-RT repeated is a simple, easy to give, and non-toxic asset that could be investigated as treatment option in patients with indolent B-NHL.

[Hodgkin lymphoma: Current and future therapeutic strategies]. / Le lymphome de Hodgkin : stratégies thérapeutiques actuelles et futures.

Hodgkin lymphoma (HL) is a cancer that mostly affects young people, in which modern therapeutic strategies using chemotherapy and radiotherapy result in a cure rate exceeding 80%. Survivors are exposed to long-term consequences of treatments, such as secondary malignancies and cardiovascular diseases, whose mortality exceeds the one of the disease itself, with long-term follow-up. The current therapeutic strategy in HL, based on the assessment of initial risk factors, is the result of large clinical trials led by the main international cooperating groups. More recently, several groups have tried to develop treatment strategies adapted to the response to chemotherapy, evaluated by interim PET/CT scan. However to date, the combined treatment with chemotherapy followed by radiation therapy remains a standard in most of the above-diaphragmatic localized forms. Immune checkpoint inhibitors, and especially anti-PD1 antibodies, have shown dramatic results in some serious forms of relapsed or refractory HL, with limited toxicity, and may contribute in the future to reduce the toxicities of treatments.

Comparison of 36 Gy, 20 Gy, or No Radiation Therapy After 6 Cycles of EBVP Chemotherapy and Complete Remission in Early-Stage Hodgkin Lymphoma Without Risk Factors: Results of the EORT-GELA H9-F Intergroup Randomized Trial.

PURPOSE: While patients with early-stage Hodgkin lymphoma (HL) have an excellent outcome with combined treatment, the radiation therapy (RT) dose and treatment with chemotherapy alone remain questionable. This noninferiority trial evaluates the feasibility of reducing the dose or omitting RT after chemotherapy. METHODS AND MATERIALS: Patients with untreated supradiaphragmatic HL without risk factors (age ≥ 50 years, 4 to 5 nodal areas involved, mediastinum-thoracic ratio ≥ 0.35, and erythrocyte sedimentation rate ≥ 50 mm in first hour without B symptoms or erythrocyte sedimentation rate ≥ 30 mm in first hour with B symptoms) were eligible for the trial. Patients in complete remission after chemotherapy were randomized to no RT, low-dose RT (20 Gy in 10 fractions), or standard-dose involved-field RT (36 Gy in 18 fractions). The limit of noninferiority was 10% for the difference between 5-year relapse-free survival (RFS) estimates. From September 1998 to May 2004, 783 patients received 6 cycles of epirubicin, bleomycin, vinblastine, and prednisone; 592 achieved complete remission or unconfirmed complete remission, of whom 578 were randomized to receive 36 Gy (n=239), 20 Gy of involved-field RT (n=209), or no RT (n=130). RESULTS: Randomization to the no-RT arm was prematurely stopped (≥20% rate of inacceptable events: toxicity, treatment modification, early relapse, or death). Results in the 20-Gy arm (5-year RFS, 84.2%) were not inferior to those in the 36-Gy arm (5-year RFS, 88.6%) (difference, 4.4%; 90% confidence interval [CI] -1.2% to 9.9%). A difference of 16.5% (90% CI 8.0%-25.0%) in 5-year RFS estimates was observed between the no-RT arm (69.8%) and the 36-Gy arm (86.3%); the hazard ratio was 2.55 (95% CI 1.44-4.53; P<.001). The 5-year overall survival estimates ranged from 97% to 99%. CONCLUSIONS: In adult patients with early-stage HL without risk factors in complete remission after epirubicin, bleomycin, vinblastine, and prednisone chemotherapy, the RT dose may be limited to 20 Gy without compromising disease control. Omitting RT in these patients may jeopardize the treatment outcome.

Challenges and perspectives in the immunotherapy of Hodgkin lymphoma.

Hodgkin lymphoma (HL) was one of the first few cancers to be cured first with radiotherapy alone and then with a combination of chemotherapy and radiotherapy. Around 80% of the patients with HL will be cured by first-line therapy. However, the ionising radiation not only produces cytotoxicity but also induces alterations in the microenvironment, and patients often struggle with the long-term consequences of these treatments, such as cardiovascular disorders, lung diseases and secondary malignancies. Hence, it is essential to improve treatments while avoiding delayed side-effects. Immunotherapy is a promising new treatment option for Hodgkin lymphoma, and anti- programmed death-1 (PD1) agents have produced striking results in patients with relapsed or refractory disease. The microenvironment of Hodgkin lymphoma appears to be unique in the field of human disease: the malignant Reed-Sternberg cells only constitute 1% of the cells in the lymphoma, but they are surrounded by an extensive immune infiltrate. Reed-Sternberg cells exhibit 9p24.1/PD-L1/PD-L2 copy number alterations and genetic rearrangements associated with programmed cell death ligand 1/ ligand 2 (PD-L1/2) overexpression, together with major histocompatibility complex-I (MHC-I) and major histocompatibility complex-II (MHC-II) downregulation (which may facilitate the tumour's immune evasion). Although HL may be a situation in which defective immune surveillance is restored by anti-PD1 therapy, it challenges our current explanation of how anti-PD1 agents work because MHC-I expression is required for CD8-T-cell-mediated tumour antigen recognition. Here, we review recent attempts to understand the defects in immune recognition in HL and to design an optimal evidence-based treatment for combination with anti-PD1.

ABVD or BEACOPPbaseline along with involved-field radiotherapy in early-stage Hodgkin Lymphoma with risk factors: Results of the European Organisation for Research and Treatment of Cancer (EORTC)-Groupe d'Étude des Lymphomes de l'Adulte (GELA) H9-U intergroup randomised trial.

PURPOSE: For early-stage Hodgkin lymphoma (HL), optimal chemotherapy regimen and the number of cycles to be delivered remain to settle down. The H9-U trial compared three modalities of chemotherapy followed by involved-field radiotherapy (IFRT) in patients with stage I-II HL and risk factors (NCT00005584). PATIENTS AND METHODS: Patients aged 15-70 years with untreated supradiaphragmatic HL with at least one risk factor (age ≥ 50, involvement of 4-5 nodal areas, mediastinum/thoracic ratio ≥ 0.35, erythrocyte sedimentation rate (ESR) ≥ 50 without B-symptoms or ESR ≥ 30 and B-symptoms) were eligible for the randomised, open label, multicentre, non-inferiority H9-U trial. The limit of non-inferiority was set at 10% for the difference between 5-year event-free survival (EFS) estimates. From October 1998 to September 2002, 808 patients were randomised to receive either the control arm 6-ABVD-IFRT (n = 276), or one of the two experimental arms: 4-ABVD-IFRT (n = 277) or 4-BEACOPPbaseline-IFRT (n = 255). RESULTS: Results in the 4-ABVD-IFRT (5-year EFS, 85.9%) and the 4-BEACOPPbaseline-IFRT (5-year EFS, 88.8%) were not inferior to 6-ABVD-IFRT (5-year EFS, 89.9%): difference of 4.0% (90%CI, -0.7%-8.8%) and of 1.1% (90%CI,-3.5%-5.6%) respectively. The 5-year overall survival estimates were 94%, 93%, and 93%, respectively. Patients treated with combined modality treatment chemotherapeutic regimen comprising doxorubicin (Adriamycin), bleomycin, vincristine (Oncovin), cyclophosphamide, procarbazine, etoposide and prednisone (BEACOPP)baseline more often developed serious adverse events requiring supportive measures and hospitalisation compared with patients receiving the chemotherapeutic regimen comprising doxorubicin (Adriamycin), bleomycin, vinblastine and dacarbazine (ABVD). CONCLUSIONS: The trial demonstrates that 4-ABVD followed by IFRT yields high disease control in patients with early-stage HL and risk factors responding to chemotherapy. Although non-inferior in terms of efficacy, four cycles of BEACOPPbaseline were more toxic than four or six cycles of ABVD.

Poor predictive value of positive interim FDG-PET/CT in primary mediastinal large B-cell lymphoma.

PURPOSE: Though commonly used to assess response to therapy, the prognostic value of interim FDG-PET/CT in Primary Mediastinal Large B-cell Lymphoma (PMBCL) is unclear. METHODS: We conducted a retrospective study on 36 consecutive patients treated at our institution for a PMBCL between 2006 and 2014. All patients with a positive interim FDG-PET/CT had undergone histological restaging consisting either in a surgical debulking of the residual lesion (15 patients) or a CT-guided core needle biopsy (two patients). All FDG-PET/CT were secondarily reviewed according to the more recent Deauville criteria. RESULTS: Interim FDG-PET/CT was considered positive in 17/36 patients using visual evaluation. Among these patients, 14 had a Deauville score of 4. Histological restaging was negative in all but one case, showing inflammation and/or fibrosis. After a median follow-up of 48.5 months, a total of five patients have relapsed, two patients in the positive FDG-PET/CT group, and three patients in the negative FDG-PET/CT group, respectively. CONCLUSIONS: These data indicate that a positive interim FDG-PET/CT does not reflect persistence of active disease in the vast majority of PMBCL cases. The relapse rate appears similar regardless of interim FDG-PET/CT results and interpretation criteria. This suggests that interim FDG-PET/CT has a poor positive predictive value, thus kt should be used with caution in PMBCL.

Early Positron Emission Tomography Response-Adapted Treatment in Stage I and II Hodgkin Lymphoma: Final Results of the Randomized EORTC/LYSA/FIL H10 Trial.

Purpose Patients who receive combined modality treatment for stage I and II Hodgkin lymphoma (HL) have an excellent outcome. Early response evaluation with positron emission tomography (PET) scan may improve selection of patients who need reduced or more intensive treatments. Methods We performed a randomized trial to evaluate treatment adaptation on the basis of early PET (ePET) after two cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) in previously untreated-according to European Organisation for Research and Treatment of Cancer criteria favorable (F) and unfavorable (U)-stage I and II HL. The standard arm consisted of ABVD followed by involved-node radiotherapy (INRT), regardless of ePET result. In the experimental arm, ePET-negative patients received ABVD only (noninferiority design), whereas ePET-positive patients switched to two cycles of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPPesc) and INRT (superiority design). Primary end point was progression-free survival (PFS). Results Of 1,950 randomly assigned patients, 1,925 received an ePET-361 patients (18.8%) were positive. In ePET-positive patients, 5-year PFS improved from 77.4% for standard ABVD + INRT to 90.6% for intensification to BEACOPPesc + INRT (hazard ratio [HR], 0.42; 95% CI, 0.23 to 0.74; P = .002). In ePET-negative patients, 5-year PFS rates in the F group were 99.0% versus 87.1% (HR, 15.8; 95% CI, 3.8 to 66.1) in favor of ABVD + INRT; the U group, 92.1% versus 89.6% (HR, 1.45; 95% CI, 0.8 to 2.5) in favor of ABVD + INRT. For both F and U groups, noninferiority of ABVD only compared with combined modality treatment could not be demonstrated. Conclusion In stage I and II HL, PET response after two cycles of ABVD allows for early treatment adaptation. When ePET is positive after two cycles of ABVD, switching to BEACOPPesc + INRT significantly improved 5-year PFS. In ePET-negative patients, noninferiority of ABVD only could not be demonstrated: risk of relapse is increased when INRT is omitted, especially in patients in the F group.

Combination of ofatumumab and reduced-dose CHOP for diffuse large B-cell lymphomas in patients aged 80 years or older: an open-label, multicentre, single-arm, phase 2 trial from the LYSA group.

BACKGROUND: In 2011 we reported a rituximab plus miniCHOP (reduced-dose cyclophosphamide, doxorubicin, vincristine, and prednisone) combination for patients older than 80 years with diffuse large B-cell lymphoma (DLBCL). The 2-year overall survival was 59% (95% CI 49-67) with an excess of early toxicity. To improve those results we tested the same chemotherapy protocol in combination with ofatumumab and a pre-phase treatment. METHODS: For this open-label, multicentre, single-group, phase 2 trial, we recruited patients older than 80 years with untreated histologically-proven CD20-positive DLBCL, Ann Arbor stage I to IV, from 41 academic and hospital centres in France and Belgium. Patients received a pre-phase with oral vincristine (1 mg total dose 1 week before cycle 1 [day -7]) and oral prednisone (60 mg total dose starting 1 week before cycle 1, for 4 days [day -7 to day -4]) before the first cycle of the ofatumumab plus miniCHOP regimen. The regimen consisted of 1000 mg total dose of intravenous ofatumumab, 25 mg/m2 of intravenous doxorubicin, 400 mg/m2 of intravenous cyclophosphamide, and 1 mg of intravenous vincristine, on day 1 of each cycle; and 40 mg/m2 of oral prednisone on days 1-5. Ofatumumab was administered with 1000 mg of paracetamol and 50 mg of diphenhydramine. The primary endpoint was overall survival in the intention-to-treat population. The statistical analysis has been done on an intention-to-treat principle. This study was registered with ClinicalTrials.gov, number NCT01195714. FINDINGS: Between June 2, 2010, and Nov 4, 2011, we enrolled 120 patients. Age-adjusted International Prognostic Index was 2-3 in 68 (57%) of them. The median follow-up time was 26·8 months (IQR 24·5-30·1). The 2-year overall survival was 64·7% (95% CI 55·3-72·7) and median overall survival was not reached (95% CI 30·2-not reached). 45 patients died during the treatment, of whom 28 (62%) died due to lymphoma. The most common side-effect was haematological toxicity. Among the 120 patients, grade 3-4 neutropenia was reported in 24 (21%) patients and thrombocytopenia in two (2%), during the treatment period. Grade 3-4 anaemia was reported in six (5%) patients; seven (6%) patients had one episode of febrile neutropenia. 17 (15%) of 115 patients in the modified intention-to-treat population had red blood cell transfusions and three (3%) had platelet transfusions. INTERPRETATION: Our result suggest that, in patients older than 80 years with DLBCL, ofatumumab and pre-phase treatment seem to improve overall survival compared with the previously reported data. The combination of pre-phase treatment, a monoclonal antibody against CD20, and miniCHOP can be considered a new treatment platform for use in randomised clinical trial design for DLBCL treatment in patients older than 80 years.

[Consortium for detection and management of lung damage induced by bleomycin]. / Consortium de détection et prise en charge des atteintes pulmonaires induites par la bléomycine.

Bleomycin is a cytotoxic antibiotic and a component of chemotherapy regimens of germ cell tumors and lymphoma. Bleomycin lung injuries occur in 10% of patients, and lead to severe interstitial pneumonia in 3% of patients. Pulmonary toxicity is related to endothelial cells injury induce by free radicals and inflammatory cytokines. Diagnosis of bleomycin-induced lung toxicity is based on the combination of clinical and radiological features, and requires to rule out differential diagnoses including pneumocystis. "Bleomycin-induced pneumonitis" is the most frequent pattern; eosinophilic pneumonitis and organizing pneumonia are rarer. Occurrence of bleomycin lung toxicity requires an immediate and often permanent discontinuation. Treatment is based on steroid. Regular clinical and pulmonary function tests monitoring are mandatory for early detection of bleomycin-induced lung toxicity.

Eight Cycles of ABVD Versus Four Cycles of BEACOPPescalated Plus Four Cycles of BEACOPPbaseline in Stage III to IV, International Prognostic Score ≥ 3, High-Risk Hodgkin Lymphoma: First Results of the Phase III EORTC 20012 Intergroup Trial.

PURPOSE: To compare patients with high-risk stage III to IV Hodgkin lymphoma (HL) in the phase III European Organisation for Research and Treatment of Cancer 20012 Intergroup trial (Comparison of Two Combination Chemotherapy Regimens in Treating Patients With Stage III or Stage IV Hodgkin's Lymphoma) who were randomly assigned to either doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) or to bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP). PATIENTS AND METHODS: Patients with clinical stage III or IV HL, International Prognostic Score of 3 or higher, and age 60 years or younger received ABVD for eight cycles (ABVD8) or escalated-dose BEACOPP (BEACOPPescalated) for four cycles followed by baseline BEACOPP (BEACOPPbaseline) for four cycles (BEACOPP4+4) without radiotherapy. Primary end points were event-free survival (EFS), treatment discontinuation, no complete response (CR) or unconfirmed complete response (CRu) after eight cycles, progression, relapse, or death. Secondary end points were CR rate, overall survival (OS), quality of life, secondary malignancies, and disease-free survival in CR/CRu patients. RESULTS: Between 2002 and 2010, 549 patients were randomly assigned to ABVD8 (n = 275) or BEACOPP4+4 (n = 274). Other characteristics included median age, 35 years; male, 75%; stage IV, 74%; "B" symptoms, 81%; and International Prognostic Score ≥ 4, 59%. WHO performance status was 0 (34%), 1 (48%), or 2 (17%). Median follow-up was 3.6 years. CR/CRu was 82.5% in both arms. At 4 years, EFS was 63.7% for ABVD8 versus 69.3% for BEACOPP4+4 (hazard ratio [HR], 0.86; 95% CI, 0.64 to 1.15; P = .312); disease-free survival was 85.8% versus 91.0% (HR, 0.59; 95% CI, 0.33 to 1.06; P = .076), and OS was 86.7% versus 90.3% (HR, 0.71; 95% CI, 0.42 to 1.21; P = .208). Death as a result of toxicity occurred in six and five patients, early discontinuation (before cycle 5) in 12 and 26 patients, treatment crossovers in five and 10 patients, and secondary malignancies in eight and 10 patients in the ABVD8 and BEACOPP4+4 arms, respectively. CONCLUSION: ABVD8 and BEACOPP4+4 resulted in similar EFS and OS in patients with high-risk advanced-stage HL. Because BEACOPP4+4 did not demonstrate a favorable effectiveness or toxicity ratio compared with ABVD8, treatment burden, immediate and late toxicities, and associated costs must be considered before selecting one of these regimens on which to build future treatment strategies.

Nodular lymphocyte predominant Hodgkin lymphoma: a Lymphoma Study Association retrospective study.

Nodular lymphocyte predominant Hodgkin lymphoma represents a distinct entity from classical Hodgkin lymphoma. We conducted a retrospective study to investigate the management of patients with nodular lymphocyte predominant Hodgkin lymphoma. Clinical characteristics, treatment and outcome of adult patients with nodular lymphocyte predominant Hodgkin lymphoma were collected in Lymphoma Study Association centers. Progression-free survival (PFS) and overall survival (OS) were analyzed, and the competing risks formulation of a Cox regression model was used to control the effect of risk factors on relapse or death as competing events. Among 314 evaluable patients, 82.5% had early stage nodular lymphocyte predominant Hodgkin lymphoma. Initial management consisted in watchful waiting (36.3%), radiotherapy (20.1%), rituximab (8.9%), chemotherapy or immuno-chemotherapy (21.7%), combined modality treatment (12.7%), or radiotherapy plus rituximab (0.3%). With a median follow-up of 55.8 months, the 10-year PFS and OS estimates were 44.2% and 94.9%, respectively. The 4-year PFS estimates were 79.6% after radiotherapy, 77.0% after rituximab alone, 78.8% after chemotherapy or immuno-chemotherapy, and 93.9% after combined modality treatment. For the whole population, early treatment with chemotherapy or radiotherapy, but not rituximab alone (Hazard ratio 0.695 [0.320-1.512], P=0.3593) significantly reduced the risk of progression compared to watchful waiting (HR 0.388 [0.234-0.643], P=0.0002). Early treatment appears more beneficial compared to watchful waiting in terms of progression-free survival, but has no impact on overall survival. Radiotherapy in selected early stage nodular lymphocyte predominant Hodgkin lymphoma, and combined modality treatment, chemotherapy or immuno-chemotherapy for other patients, are the main options to treat adult patients with a curative intent.

Concurrent Etoposide, Steroid, High-dose Ara-C and Platinum chemotherapy with radiation therapy in localised extranodal natural killer (NK)/T-cell lymphoma, nasal type.

PURPOSE: Radiation combined with chemotherapy has recently been proposed to treat patients with localised extranodal natural killer (NK)/T lymphoma (ENKTL), nasal type. However, the modalities of the chemoradiotherapy combination and drug choices remain a matter of debate. We conducted a concurrent chemoradiotherapy (CCRT) study with the ESHAP (Etoposide, Steroid, High-dose Ara-C and Platinum) regimen. METHODS: An induction phase with two upfront courses of CCRT delivering a 40Gy dose of radiation concurrently with two cycles of the ESHAP chemotherapy regimen, followed by a consolidation phase with 2-3 cycles of ESHAP chemotherapy alone. RESULTS: Thirteen patients with localised ENKTL nasal type were enrolled between January 2005 and December 2014. The median age was 62years. Ten and three patients had Ann Arbor stage IE and IIE disease, respectively. They all completed the induction CCRT phase. A median of two consolidation ESHAP cycles were delivered. During consolidation, 8/13 (62%) patients had a reduction in the number of chemotherapy cycles or reduced chemotherapy doses, due to haematologically adverse events. The other five patients (38%) received the full number of ESHAP cycles of chemotherapy scheduled without a dose reduction. All but one patient (92%) experienced grade 3-4 haematological toxicity. The main non-haematological grade 3-4 toxicity was mucositis in 6/13 (46%) patients. All but one patient (92%) achieved a complete remission. Two-year overall survival was 72%. CONCLUSIONS: With optimal management of the specific toxicities induced by this treatment modality, CCRT with the ESHAP regimen yielded high efficacy against localised ENKTL, nasal type.

Young patients with non-germinal center B-cell-like diffuse large B-cell lymphoma benefit from intensified chemotherapy with ACVBP plus rituximab compared with CHOP plus rituximab: analysis of data from the Groupe d'Etudes des Lymphomes de l'Adulte/lymphoma study association phase III trial LNH 03-2B.

PURPOSE: To determine whether any tumor biomarkers could account for the survival advantage observed in the LNH 03-2B trial among patients with diffuse large B-cell lymphoma (DLBCL) and low-intermediate risk according to the International Prognostic Index when treated with dose-intensive rituximab, doxorubicin, cyclophosphamide, vindesine, bleomycin, and prednisone (R-ACVBP) compared with standard rituximab, doxorubicin, cyclophosphamide, vincristine, and prednisone (R-CHOP). PATIENTS AND METHODS: Using immunohistochemistry, expression of CD10, BCL6, MUM1, MYC, and BCL2 and coexpression of MYC/BCL2 were examined. The interaction effects between each biomarker and treatment arm on survival were studied in a restricted model and a full model incorporating clinical parameters. RESULTS: Among the 379 patients analyzed in the trial, 229 tumors were evaluable for germinal center B-cell-like (GCB)/non-GCB subclassification according to the Hans algorithm. Among all the biomarkers, only the interaction between the Hans algorithm and the treatment arm was significant for progression-free survival (PFS) and overall survival (OS) in univariable (PFS, P = .04; OS, P = .01) and multivariable (PFS, P = .03; OS, P = .01) analyses. Non-GCB tumors predicted worse PFS (hazard ratio [HR], 3.21; 95% CI, 1.29 to 8.00; P = .01) and OS (HR, 6.09; 95% CI, 1.37 to 27.03; P = .02) among patients treated with R-CHOP compared with patients who received R-ACVBP, whereas there were no significant survival differences between these regimens among patients with GCB tumors. CONCLUSION: The survival benefit related to R-ACVBP over R-CHOP is at least partly linked to improved survival among patients with non-GCB DLBCL. Therefore, the Hans algorithm could be considered a theragnostic biomarker for selecting young patients with DLBCL who can benefit from an intensified R-ACVBP immunochemotherapy regimen.

Sarcoidosis occurring after lymphoma: report of 14 patients and review of the literature.

Sarcoidosis is a granulomatous disease that most frequently affects the lungs with pulmonary infiltrates and/or bilateral hilar and mediastinal lymphadenopathy. An association of sarcoidosis and lymphoproliferative disease has previously been reported as the sarcoidosis-lymphoma syndrome. Although this syndrome is characterized by sarcoidosis preceding lymphoma, very few cases of sarcoidosis following lymphoma have been reported. We describe the clinical, biological, and radiological characteristics and outcome of 39 patients presenting with sarcoidosis following lymphoproliferative disease, including 14 previously unreported cases and 25 additional patients, after performing a literature review. Hodgkin lymphoma and non-Hodgkin lymphoma were equally represented. The median delay between lymphoma and sarcoidosis was 18 months. Only 16 patients (41%) required treatment. Sarcoidosis was of mild intensity or self-healing in most cases, and overall clinical response to sarcoidosis was excellent with complete clinical response in 91% of patients. Sarcoidosis was identified after a follow-up computerized tomography scan (CT-scan) or fluorodeoxyglucose-positron emission tomography/computerized tomography (FDG-PET/CT) evaluation in 18/34 patients (53%). Sarcoidosis is therefore a differential diagnosis to consider when lymphoma relapse is suspected on a CT-scan or FDG-PET/CT, emphasizing the necessity to rely on histological confirmation of lymphoma relapse.
