ANTIFON-CLIC®, a new clinical decision support system for the treatment of invasive aspergillosis: is it clinically relevant?

BACKGROUND: Invasive aspergillosis (IA) is increasing especially in new groups of patients. Despite advances in management, morbidity and mortality related to IA remain high. Thus, Clinical Decision Support System (CDSS) dedicated to IA are needed to promote the optimal antifungal for each group of patients. PATIENTS AND METHODS: This was a retrospective multicenter cohort study involving intensive care units and medical units. Adult patients who received caspofungin, isavuconazole, itraconazole, liposomal amphotericin B, posaconazole, or voriconazole, for the treatment of IA were eligible for enrollment. The primary objective was the concordance between the clinician's prescription and the prescription recommended by the CDSS. The secondary objective was the concordance according to different hospitals, departments, and indications. RESULTS: Eighty-eight patients (n=88) from three medical hospitals were included. The overall concordance was 97% (85/88) including 100% (41/41) for center A, 92% (23/25) for center B, and 95% (21/22) for center C. There was no significant difference in concordance among the hospitals (P=0.973), the departments (P=1.000), and the indications (P=0.799). The concordance was 70% (7/10) for isavuconazole due to its use as an empirical treatment and 100% (78/78) for the other antifungals. DISCUSSION: The concordance rate was high whatever the hospital, the department, and the indication. The only discrepancy was attributed to the use of isavuconazole as an empirical treatment which is a therapeutic option not included in the CDSS. CONCLUSIONS: This new CDSS dedicated to IA is meeting the clinical practice. Its implementation in routine will help to support antifungal stewardship.

Tandem versus single haematopoietic stem cell transplant and BV maintenance in relapsed/refractory Hodgkin lymphoma: A matched cohort analysis from the LYSA.

Autologous hematopoietic stem cell transplant (ASCT) is the standard curative treatment for patients with high-risk relapsed/refractory Hodgkin lymphoma (R/R HL). The AETHERA study showed survival gain with Brentuximab Vedotin (BV) maintenance after ASCT in BV-naive patients, which was recently confirmed in the retrospective AMAHRELIS cohort, including a majority of BV-exposed patients. However, this approach has not been compared to intensive tandem auto/auto or auto/allo transplant strategies, which were used before BV approval. Here, we matched BV maintenance (AMAHRELIS) and tandem SCT (HR2009) cohorts, and observed that BV maintenance was associated with better survival outcome in patients with HR R/R HL.

Thromboembolic events and thromboprophylaxis associated with immunomodulators in multiple myeloma patients: a real-life study.

PURPOSE: The aim of this study is to assess international guidelines implementation concerning thromboprophylaxis strategy in myeloma patients treated with immunomodulatory drugs. METHODS: This retrospective study includes multiple myeloma patients treated with immunomodulatory drugs between 2014 and 2017 in the Hematology department of a teaching hospital (Hospices Civils de Lyon, France) and followed by the multidisciplinary care plan for cancer outpatients ONCORAL (ONCological care for outpatients with ORAL anticancer drugs). Data from immunomodulatory drugs administration, thromboprophylaxis strategy and thrombotic events were collected from medical files. Adherence to 2010 International Myeloma Working Group (IMWG) guidelines was assessed. RESULTS: 213 patients received at least one immunomodulatory drug: lenalidomide (60.9%), pomalidomide (24.0%) and thalidomide (15.1%). About two third of treatment lines (66.2%) were in accordance with IMWG recommendations. Among the others, 30.5% and 69.5% had thromboprophylaxis, respectively, superior or inferior to IMWG recommendations. 37 venous thrombotic events and 4 arterial thromboembolisms (one patient experienced both a stroke and deep venous thrombosis simultaneously) were reported. CONCLUSION: Thromboprophylaxis was systematically performed in myeloma patients treated with immunomodulatory drugs in this real-life retrospective cohort. However, the choice of anticoagulant or anti-platelet agent remains debatable, as adherence to existing guidelines was variable.

Risk of relapse after anti-PD1 discontinuation in patients with Hodgkin lymphoma.

INTRODUCTION: Patients with relapsed/refractory Hodgkin lymphoma (R/R HL) experience high response rates upon anti-PD1 therapy. In these patients, the optimal duration of treatment and the risk of relapse after anti-PD1 discontinuation are unknown. METHODS: We retrospectively analyzed patients with R/R HL who responded to anti-PD1 monotherapy and discontinued the treatment either because of unacceptable toxicity or prolonged remission. A machine learning algorithm based on 17 candidate variables was trained and validated to predict progression-free survival (PFS) landmarked at the time of discontinuation of anti-PD1 therapy. RESULTS: Forty patients from 14 centers were randomly assigned to training (n = 25) and validation (n = 15) sets. At the time of anti-PD1 discontinuation, patients had received treatment for a median duration of 11.2 (range, 0-time to best response was not statistically significant in discriminating patients with PFS lesser or greater than 12 months). Considering PFS status as a binary variable (alive or dead) at a specific time point (12 months) is convenient, intuitive and allows for comparing the value of potential predicting variables in these two groups of patients. Nonetheless, this approach has two drawbacks: first, it binarizes outcome; second, it excludes patients alive with a time to last follow up lesser 12 months. Therefore, it is less powerful to demonstrate statistically significant association with PFS even if it exists 5 months. Patients discontinued anti-PD1 treatment either because of prolonged remission (N = 27, 67.5%) or unacceptable toxicity (N = 13, 32.5%). Most patients were in CR (N = 35, 87.5%) at the time of anti-PD1 discontinuation. In the training set, the machine learning algorithm identified that the most important variables to predict PFS were patients' age, time to best response, and presence or absence of CR. The performance observed in the training set was validated in the validation set. CONCLUSION: In this pilot, proof of concept study using a machine learning algorithm, we identified biomarkers capable of predicting the risk of relapse after anti-PD1 discontinuation (age, time to best response, quality of response). Once confirmed, these simple biomarkers will represent useful tools to guide the management of these patients.

Ibrutinib monotherapy for relapse or refractory primary CNS lymphoma and primary vitreoretinal lymphoma: Final analysis of the phase II 'proof-of-concept' iLOC study by the Lymphoma study association (LYSA) and the French oculo-cerebral lymphoma (LOC) network.

BACKGROUND: Primary central nervous system lymphomas (PCNSLs) are mainly diffuse large B-cell lymphomas (DLBCLs) of the non-germinal centre B-cell subtype, with unmet medical needs. This study aimed to evaluate the efficacy and toxicity of ibrutinib in DLBCL-PCNSL PATIENTS AND METHODS: This prospective, multicentre, phase II study involved patients with relapse or refractory(R/R) DLBCL-PCNSL or primary vitreoretinal lymphoma. The treatment consisted of ibrutinib (560 mg/day) until disease progression or unacceptable toxicity occurred. The primary outcome was the disease control (DC) rate after two months of treatment (P0 < 10%; P1 > 30%). RESULTS: Fifty-two patients were recruited. Forty-four patients were evaluable for response. After 2 months of treatment, the DC was 70% in evaluable patients and 62% in the intent-to-treat analysis, including 10 complete responses (19%), 17 partial responses (33%) and 5 stable diseases (10%). With a median follow-up of 25.7 months (range, 0.7-30.5), the median progression-free and overall survivals were 4.8 months (95% confidence interval [CI]; 2.8-12.7) and 19.2 months (95% CI; 7.2-NR), respectively. Thirteen patients received ibrutinib for more than 12 months. Two patients experienced pulmonary aspergillosis with a favourable (n = 1) or fatal outcome (n = 1). Ibrutinib was detectable in the cerebrospinal fluid (CSF). The clinical response to ibrutinib seemed independent of the gene mutations in the BCR pathway. CONCLUSION: Ibrutinib showed clinical activity in the brain, the CSF and the intraocular compartment and was tolerated in R/R PCNSL. The addition of ibrutinib to standard methotrexate-base induction chemotherapy will be further evaluated in the first-line treatment. CLINICAL TRIAL NUMBER: NCT02542514.

Lenalidomide in combination with intravenous rituximab (REVRI) in relapsed/refractory primary CNS lymphoma or primary intraocular lymphoma: a multicenter prospective 'proof of concept' phase II study of the French Oculo-Cerebral lymphoma (LOC) Network and the Lymphoma Study Association (LYSA)†.

BACKGROUND: Primary central nervous system lymphomas (PCNSLs) are mainly diffuse large B-cell lymphomas (DLBCLs) of the non-germinal center B-cell (non-GCB) subtype. This study aimed to determine the efficacy of rituximab plus lenalidomide (R2) in DLBCL-PCNSL. PATIENTS AND METHODS: Patients with refractory/relapsed (R/R) DLBCL-PCNSL or primary vitreoretinal lymphoma (PVRL) were included in this prospective phase II study. The induction treatment consisted of eight 28-day cycles of R2 (rituximab 375/m2 i.v. D1; lenalidomide 20 mg/day, D1-21 for cycle 1; and 25 mg/day, D1-21 for the subsequent cycles); in responding patients, the induction treatment was followed by a maintenance phase comprising 12 28-day cycles of lenalidomide alone (10 mg/day, D1-21). The primary end point was the overall response rate (ORR) at the end of induction (P0 = 10%; P1 = 30%). RESULTS: Fifty patients were included. Forty-five patients (PCNSL, N = 34; PVRL, N = 11) were assessable for response. The ORR at the end of induction was 35.6% (95% CI 21.9-51.2) in assessable patients and 32.0% (95% CI 21.9-51.2) in the intent-to-treat analysis, including 13 complete responses (CR)/unconfirmed CR (uCR; 29%) and 3 partial responses (PR; 7%). The best responses were 18 CR/uCR (40%) and 12 PR (27%) during the induction phase. The maintenance phase was started and completed by 18 and 5 patients, respectively. With a median follow-up of 19.2 months (range 1.5-31), the median progression-free survival (PFS) and overall survival (OS) were 7.8 months (95% CI 3.9-11.3) and 17.7 months (95% CI 12.9 to not reached), respectively. No unexpected toxicity was observed. The peripheral baseline CD4/CD8 ratio impacted PFS [median PFS = 9.5 months (95% CI, 8.1-14.8] for CD4/CD8 ≥ 1.6; median PFS = 2.8 months, [95% CI, 1.1-7.8) for CD4/CD8 < 1.6, P = 0.03). CONCLUSIONS: The R2 regimen showed significant activity in R/R PCNSL and PVRL patients. These results support assessments of the efficacy of R2 combined with methotrexate-based chemotherapy as a first-line treatment of PCNSL. CLINICAL TRIALS NUMBER: NCT01956695.

Progression-free survival at 24 months (PFS24) and subsequent outcome for patients with diffuse large B-cell lymphoma (DLBCL) enrolled on randomized clinical trials.

Background: Patients with diffuse large B-cell lymphoma treated with first-line anthracycline-based immunochemotherapy and remaining in remission at 2 years have excellent outcomes. This study assessed overall survival (OS) stratified by progression-free survival (PFS) at 24 months (PFS24) using individual patient data from patients with DLBCL enrolled in multi-center, international randomized clinical trials as part of the Surrogate Endpoint for Aggressive Lymphoma (SEAL) Collaboration. Patients and methods: PFS24 was defined as being alive and PFS24 after study entry. OS from PFS24 was defined as time from identified PFS24 status until death due to any cause. OS was compared with each patient's age-, sex-, and country-matched general population using expected survival and standardized mortality ratios (SMRs). Results: A total of 5853 patients enrolled in trials in the SEAL database received rituximab as part of induction therapy and were included in this analysis. The median age was 62 years (range 18-92), and 56% were greater than 60 years of age. At a median follow-up of 4.4 years, 1337 patients (23%) had disease progression, 1489 (25%) had died, and 5101 had sufficient follow-up to evaluate PFS24. A total of 1423 assessable patients failed to achieve PFS24 with a median OS of 7.2 months (95% CI 6.8-8.1) after progression; 5-year OS after progression was 19% and SMR was 32.1 (95% CI 30.0-34.4). A total of 3678 patients achieved PFS24; SMR after achieving PFS24 was 1.22 (95% CI 1.09-1.37). The observed OS versus expected OS at 3, 5, and 7 years after achieving PFS24 was 93.1% versus 94.4%, 87.6% versus 89.5%, and 80.0% versus 83.7%, respectively. Conclusion: Patients treated with rituximab containing anthracycline-based immunochemotherapy on clinical trials who are alive without progression at 24 months from the onset of initial therapy have excellent outcomes with survival that is marginally lower but clinically indistinguishable from the age-, sex-, and country-matched background population for 7 years after achieving PFS24.

Role of up-front autologous stem-cell transplantation in peripheral T-cell lymphoma for patients in response after induction: an analysis of patients from LYSA centers.

Background: Peripheral T-cell lymphoma (PTCL) remains a therapeutic challenge. Due to the rarity and the heterogeneity of PTCL, no consensus has been achieved regarding even the type of first-line treatment. The benefit of autologous stem-cell transplantation (ASCT) is, therefore, still intensely debated. Patients and methods: In the absence of randomized trials addressing the role of ASCT, we performed a large multicentric retrospective study and used both a multivariate proportional hazard model and a propensity score matching approach to correct for sample selection bias between patients allocated or not to ASCT in intention-to-treat (ITT). Results: Among 527 patients screened from 14 centers in France, Belgium and Portugal, a final cohort of 269 patients ≤65 years old with PTCL-not otherwise specified (NOS) (N = 78, 29%), angioimmunoblastic T-cell lymphoma (AITL) (N = 123, 46%) and anaplastic lymphoma kinase-positive anaplastic large cell lymphoma (ALK-ALCL) (N = 68, 25%) with partial (N = 52, 19%) or complete responses (N = 217, 81%) after induction was identified and information about treatment allocation was carefully collected before therapy initiation from medical records. One hundred and thirty-four patients were allocated to ASCT in ITT and 135 were not. Neither the Cox multivariate model (HR = 1.02; 95% CI: 0.69-1.50 for PFS and HR = 1.08; 95% CI: 0.68-1.69 for OS) nor the propensity score analysis after stringent matching for potential confounding factors (logrank P = 0.90 and 0.66 for PFS and OS, respectively) found a survival advantage in favor of ASCT as a consolidation procedure for patients in response after induction. Subgroup analyses did not reveal any further difference for patients according to response status, stage disease or risk category. Conclusions: The present data do not support the use of ASCT for up-front consolidation for all patients with PTCL-NOS, AITL, or ALK-ALCL with partial or complete response after induction.

Carmustine replacement in intensive chemotherapy preceding reinjection of autologous HSCs in Hodgkin and non-Hodgkin lymphoma: a review.

High-dose chemotherapy preceding autologous hematopoietic stem cell transplantation (auto-HSCT) is one treatment option for patients with Hodgkin (HL) or non-Hodgkin lymphoma (NHL). The most frequently used intensive chemotherapy is a combination of carmustine (BCNU), etoposide, cytarabine and melphalan (BEAM). However, BCNU is consistently in short supply, and there has been a recent dramatic increase in its cost, necessitating the utilization of conditioning alternatives. The busulfan-based conditioning regimen known as the busulfan-cyclophosphamide-etoposide (BuCyE) combination is the second most-studied conditioning regimen worldwide after BEAM, and it exhibits a benefit/risk ratio that is comparable to that of BEAM. In addition to these two combinations, the present manuscript also summarizes data reported for other conditioning combinations. Owing to the lack of prospective and comparative studies, a comparison of the toxicities and medicoeconomical profiles of these treatments is warranted to identify effective replacements for BCNU-based conditioning.

Adrenal lymphoma: presentation, management and prognosis.

AIM: This study aimed to identify the clinical, radiological and prognostic features of primary adrenal lymphoma (PAL) in order to diagnose the disease more accurately. MATERIALS AND METHODS: A retrospective multi-centre study was conducted on the clinical, biological and radiological features as well as the treatment and overall survival outcomes in PAL. RESULTS: Between 1994 and 2014, 28 patients from five regions of eastern France were diagnosed with primary adrenal lymphoma. The revealing symptoms were a worsening general state (77%), weight loss (77%) and abdominal pain (42%). Biological features of PAL were almost omnipresent: increased LDH, ß2 microglobulin, CRP or ferritinaemia levels. The PAL was bilateral in 20 cases (71%), adrenal insufficiency was searched for in 11 patients and found in eight (73%). CT scans showed masses of various sizes measuring up to 180 mm. On MRI, the lesions were hypointense in T1 and hyperintense in T2. When done, positron emission tomography with fluorodeoxyglucose (FDG-PET) showed locations not seen on the CT and revealed extra-adrenal locations in 70% of examinations. Adrenalectomy brought no benefit. The overall survival rate was poor (61.9% at 2 years) despite polychemotherapy. CONCLUSION: The clinical presentation of PAL comprised major general symptoms. Adrenal insufficiency was very common in patients with bilateral involvement but was not systematically tested. PET was an efficient examination to visualize extra-adrenal locations. The preliminary results of MRI to distinguish between PAL and adrenocortical carcinoma should be confirmed. Further studies are needed to establish an optimal strategy for the management of these primary adrenal lymphomas.

Clinical characteristics and prognostic factors of plasmablastic lymphoma patients: analysis of 135 patients from the LYSA group.

Background: Plasmablastic lymphoma (PBL), initially described in 1997 in the oral cavity of HIV positive patients, is now recognized as a distinct aggressive and rare entity of diffuse large B-cells lymphoma by the World Health Organization (WHO) classification. Since the original description, others cases have been reported. However, these are largely derived from case reports or small series limiting any definitive conclusions on clinical characteristics and outcome. Patients and methods: The clinical, biological, pathological features and outcome of a cohort including 135 patients with PBL, from LYSA centers in France and Belgium, were reported and analyzed. Results: The median age was 58 years, with a male predominance. The cohort was divided into 56 HIV-positive patients, 17 post-transplant patients and 62 HIV-negative/non-transplanted patients. Within HIV-negative/non-transplanted, a relative immunosuppression was found in most cases (systemic inflammatory disease, history of cancer, increased age associated with weakened immune system). We have also described a new subtype, PBL arising in a chronic localized inflammatory site, without any sign of immunosuppression. At presentation, 19% of patients showed oral involvement. Immunophenotype showed CD138 positivity in 88% of cases and CD20 negativity in 90% of cases. Chemotherapy was administered to 80% of patients, with a complete response (CR) rate of 55%. The median overall survival (OS) was 32 months. In univariate analysis, HIV positive status showed better OS when compared with HIV negative status. In multivariate analysis, International Prognostic Index score, chemotherapy and CR were associated with survival benefit. Conclusion(s): This cohort, the largest reported to date, increases the spectrum of knowledge on PBL, rarely described. However, specific guidelines to clarify treatment are lacking, and may improve the poor prognosis of this rare disease.

[Association of lymphoma and granulomatosis: A case series]. / Association lymphome et granulomatose : à propos d'une série de cas.

PURPOSE: The sarcoidosis-lymphoma syndrome is a recognised entity. However, the presence of granulomas in patients with a haematological disease should not lead too easily to a diagnosis of sarcoidosis. The presence of granulomatous lesions during the follow-up of these patients raises diagnostic and therapeutic issues. METHODS: We included 25 patients followed by the department of haematology in a French hospital (Centre Léon-Bérard). These patients presented with granulomatous lesions. Patients with a history of sarcoidosis were excluded. We report the type of haematological disease, the time of onset of the granulomatous disease compared to that of lymphoma, associated symptoms, aetiology and outcome. Patients were divided into three groups according to the time of onset of the granulomatous lesions. RESULTS: Granulomatous lesions appeared before the haematological disease in 4 cases, was concomitant in 8 cases and appeared later in 13 remaining cases. The two main subtypes of lymphoma encountered were: diffuse large cell lymphoma (36%) and Hodgkin's lymphoma (28%). Granulomatous lesions were related to the progression of the hematological disease in 11 cases, to sarcoidosis in 4 cases, to infection in 3 cases, to drug allergy in one case, to inflammatory bowel disease in one case, to granuloma annulare in one case and was isolated in 4 cases (no identified etiology). In the group where granulomas appeared after the haematological disease, mean SUV was 11 for the haematological disease versus 6.4 for granulomas. CONCLUSION: Granulomatous diseases in lymphomas can be due to various aetiologies: infection, reaction to the haematological disease, or systemic sarcoidosis. It is an important challenge for clinicians, who can miss the diagnosis of lymphoma and or conclude to a treatment failure or a relapse. Computed tomography scan (CT-scan) or (18)F-deoxyglucose-positron emission tomography scan can help establish a diagnosis but do not replace biopsy.

Sarcoidosis and lymphoma: a comparative study.

AIM: To assess the clinical features and outcome of lymphoma when associated with sarcoidosis and to determine whether this association gives lymphoma a better prognosis. DESIGN: Multicentre retrospective cohort study. METHODS: Retrospective chart review. RESULTS: Twenty-one patients were included (9 males, 12 females). Median age at sarcoidosis diagnosis was 48 years (range: 24-68 years). In 14 cases, lymphoma occurred within a previously known sarcoidosis. Five patients received a concomitant diagnosis of sarcoidosis and lymphoma, whereas lymphoma preceded sarcoidosis in two patients. Three patients were diagnosed with Hodgkin's lymphoma and 18 patients with non-Hodgkin's lymphoma (diffuse large B-cell lymphoma (DLBCL) (n = 11), follicular lymphoma (n = 2), chronic lymphocytic leukemia/small lymphocytic lymphoma (n = 2), anaplastic large cell lymphoma ALK + (n = 1), angioimmunoblastic T-cell lymphoma (n = 1) and T-cell prolymphocytic leukemia (n = 1)). Thirteen patients were alive and in complete remission. Median age at the time of diagnosis of sarcoidosis was lower in patients with concomitant lymphoma compared with patients with sarcoidosis preceding lymphoma (34 years vs. 51 years, P = 0.01). Patients presenting with DLBCL associated with sarcoidosis were compared with DLBCL without sarcoidosis. No statistical difference was found in the risk of death or progression between the two groups (P = 0.685). CONCLUSIONS: We report here the largest series of lymphoma associated sarcoidosis patients. As opposed to previous studies, we observed a predominance of patients with DLBCL. Our study confirms the concept of the sarcoidosis-lymphoma syndrome. Large B-cell lymphoma does not have a better prognosis when associated with sarcoidosis.

First-line treatment and outcome of elderly patients with primary central nervous system lymphoma (PCNSL)--a systematic review and individual patient data meta-analysis.

BACKGROUND: To investigate prognosis and effects of first-line therapy in elderly primary central nervous system lymphoma (PCNSL) patients. PATIENTS AND METHODS: A systematic review of studies about first-line therapy in immunocompetent patients ≥60 years with PCNSL until 2014 and a meta-analysis of individual patient data from eligible studies and international collaborators were carried out. RESULTS: We identified 20 eligible studies; from 13 studies, we obtained individual data of 405 patients, which were pooled with data of 378 additional patients (N = 783). Median age and Karnofsky Performance Score (KPS) was 68 years (range: 60-90 years) and 60% (range: 10%-100%), respectively. Treatments varied greatly, 573 (73%) patients received high-dose methotrexate (HD-MTX)-based therapy. A total of 276 patients received whole-brain radiotherapy (median 36 Gy, range 28.5-70 Gy). KPS ≥ 70% was the strongest prognostic factor for mortality [hazard ratio (HR) 0.50, 95% confidence interval (CI) 0.41-0.62]. After a median follow-up of 40 months, HD-MTX-based therapy was associated with improved survival (HR 0.70, 95% CI 0.53-0.93). There was no difference between HD-MTX plus oral chemotherapy and more aggressive HD-MTX-based therapies (HR 1.39, 95% CI 0.90-2.15). Radiotherapy was associated with an improved survival, but correlated with an increased risk for neurological side-effects (odds ratio 5.23, 95% CI 2.33-11.74). CONCLUSIONS: Elderly PCNSL patients benefit from HD-MTX-based therapy, especially if combined with oral alkylating agents. More aggressive HD-MTX protocols do not seem to improve outcome. WBRT may improve outcome, but is associated with increased risk for neurological side-effects. Prospective trials for elderly PCNSL patients are warranted.

A meta-analysis of Hodgkin lymphoma reveals 19p13.3 TCF3 as a novel susceptibility locus.

Recent genome-wide association studies (GWAS) of Hodgkin lymphoma (HL) have identified associations with genetic variation at both HLA and non-HLA loci; however, much of heritable HL susceptibility remains unexplained. Here we perform a meta-analysis of three HL GWAS totaling 1,816 cases and 7,877 controls followed by replication in an independent set of 1,281 cases and 3,218 controls to find novel risk loci. We identify a novel variant at 19p13.3 associated with HL (rs1860661; odds ratio (OR)=0.81, 95% confidence interval (95% CI) = 0.76-0.86, P(combined) = 3.5 × 10(-10)), located in intron 2 of TCF3 (also known as E2A), a regulator of B- and T-cell lineage commitment known to be involved in HL pathogenesis. This meta-analysis also notes associations between previously published loci at 2p16, 5q31, 6p31, 8q24 and 10p14 and HL subtypes. We conclude that our data suggest a link between the 19p13.3 locus, including TCF3, and HL risk.

A randomised phase II study of the efficacy, safety and cost-effectiveness of pegfilgrastim and filgrastim after autologous stem cell transplant for lymphoma and myeloma (PALM study).

AIM: To evaluate in a multicentre randomised study the effect on duration of febrile neutropenia (FN), the safety and cost-effectiveness of a single subcutaneous pegfilgrastim injection compared with daily injections of filgrastim after peripheral blood stem cell transplantation in patients receiving high dose chemotherapy for myeloma and lymphoma. METHODS: Patients were randomly assigned to a single dose of pegfilgrastim at day 5 (D5) or daily filgrastim from D5 to the recovery of absolute neutrophil count (ANC) to 0.5 G/L. Duration of FN, of neutrophil and platelet recovery, transfusion and antibiotic requirements were the main end-points of the study. Costs were calculated from D0 until transplant unit discharge. The incremental cost-effectiveness ratio was expressed as the cost per day of FN prevented. Probabilistic sensitivity analysis was performed by non-parametric bootstrap methods. RESULTS: Between October 2008 and September 2009, 10 centres enrolled 151 patients: 80 patients with lymphoma and 71 patients with myeloma. The mean duration of FN was 3.07 days (standard deviation (SD) 1.96) in the pegfilgrastin arm and 3.29 (SD 2.54) in the filgrastim one. Mean total costs were 23,256 and 25,448 euros for pegfilgrastim and filgrastim patients, respectively. There was a 62% probability that pegfilgrastim strictly dominates filgrastim. CONCLUDING STATEMENT: Pegfilgrastim after PBSC transplantation in myeloma and lymphoma is safe, effective when compared with filgrastim and could represent a cost-effective alternative in this setting.

[Practice guidelines of the use of bisphosphonates in solid tumours with bone metastases and in multiple myeloma]. / Guide de recommandations d'utilisation des bisphosphonates dans les lésions osseuses malignes des tumeurs solides et du myélome multiple.

Bisphosphonates are indicated for the treatment of bone lesions in patients with solid tumours or multiple myeloma. Bisphosphonates have proven their effectiveness in reducing the number of bone complications (hypercalcemia, pain, disease-related fractures, spinal cord compression) and delaying their occurrence in patients with bone tumours; they have also been shown to reduce the need for bone surgery and palliative or pain-relieving radiotherapy in these patients. International recommendations for the treatment of bone lesions related to malignant solid tumours and multiple myeloma have been established. We have elaborated clinical practice guidelines on the use of bisphosphonates to assist treatment decision-making in bone oncology. The guide contains decision trees and tables with information to guide pre-treatment evaluation and patient follow-up, as well as indications and conditions of use of bisphosphonates. In 2007, the regional cancer network of Rhône-Alpes, ONCORA, formed a working group (GIP ONCORA) to elaborate the guideline. The final version was then discussed and adopted at a plenary session in July 2009, during a collaborative workshop on supportive care recommendations organized by ONCORA and the regional cancer network of Lorraine.
