Realâworld clinical effectiveness and safety of CTâP10 in patients with diffuse large Bâcell lymphoma: An observational study in Europe
The rituximab biosimilar CTâP10 is approved for the treatment of nonâHodgkin lymphoma. Previous studies have demonstrated clinical similarity between CTâP10 and reference rituximab. However, realâworld data relating to treatment in patients with DLBCL with rituximab biosimilars are limited. This study collected realâworld data relating to the effectiveness and safety of CTâP10 treatment from the medical records of 389 patients with DLBCL (24 centers, five European countries). For the primary outcome (clinical effectiveness), overall survival (OS), progressionâfree survival (PFS), and best response (BR) were assessed. The percentage (95% confidence interval [95% CI]) of patients alive at 12â, 18â, and 30 months postindex (initiation of CTâP10) was 86% (82.4%â89.4%), 81% (76.9%â84.9%), and 76% (71.2%â80.1%), respectively. The PFS rate (percent, [95% CI]) at 12â, 18â, and 30 months postindex was 78% (74.2%â82.5%), 72% (67.9%â76.9%), and 67% (61.9%â71.7%), respectively. Median OS/PFS was not reached. For 82% (n = 312) of patients, the BR to CTâP10 was a complete response. Adverse events were consistent with known effects of chemotherapy. This international, multicenter study provides realâworld data on the safety and effectiveness profile of CTâP10 for DLBCL treatment and supports the adoption of CTâP10 for the treatment of DLBCL
Impact of treatment with iron chelation therapy in patients with lower-risk myelodysplastic syndromes participating in the European MDS registry
Iron overload due to red blood cell transfusions is associated with morbidity and mortality in lower-risk myelodysplastic syndrome patients. Many studies suggested improved survival after iron chelation therapy, but valid data are limited. The aim of this study was to assess the effect of iron chelation on overall survival and hematological improvement in lower-risk myelodysplastic syndrome patients in the European MDS registry. We compared chelated patients with a contemporary, non-chelated control group within the European MDS registry, that met the eligibility criteria for starting iron chelation. A Cox proportional hazards model was used to assess overall survival, treating receipt of chelation as a time-varying variable. Additionally, chelated and non-chelated patients were compared using a propensity-score matched model. Of 2200 patients, 224 received iron chelation. The hazard ratio and 95% confidence interval for overall survival for chelated patients, adjusted for age, sex, comorbidity, performance status, cumulative red blood cell transfusions, IPSS-R, and presence of ringed sideroblasts was 0.50 (0.34-0.74). The propensity-score analysis, matched for age, sex, country, red blood cell transfusion intensity, ferritin level, comorbidity, performance status, and IPSS-R and additionally corrected for cumulative red blood cell transfusions and presence of ringed sideroblasts, demonstrated a significantly improved overall survival for chelated patients with a hazard ratio of 0.42 (0.27-0.63) compared to non-chelated patients. Up to 39% of chelated patients reached an erythroid response. In conclusion, our results suggest that iron chelation may improve overall survival and hematopoiesis in transfused lower-risk myelodysplastic syndrome patients.

Exome sequencing identifies germline variants in DIS3 in familial multiple myeloma
[Excerpt] Multiple myeloma (MM) is the third most common hematological malignancy, after Non-Hodgkin Lymphoma and Leukemia. MM is generally preceded by Monoclonal Gammopathy of Undetermined Significance (MGUS) [1], and epidemiological studies have identified older age, male gender, family history, and MGUS as risk factors for developing MM [2].
The somatic mutational landscape of sporadic MM has been increasingly investigated, aiming to identify recurrent genetic events involved in myelomagenesis. Whole exome and whole genome sequencing studies have shown that MM is a genetically heterogeneous disease that evolves through accumulation of both clonal and subclonal driver mutations [3] and identified recurrently somatically mutated genes, including KRAS, NRAS, FAM46C, TP53, DIS3, BRAF, TRAF3, CYLD, RB1 and PRDM1 [3,4,5].
Despite the fact that family-based studies have provided data consistent with an inherited genetic susceptibility to MM compatible with Mendelian transmission [6], the molecular basis of inherited MM predisposition is only partly understood. Genome-Wide Association (GWAS) studies have identified and validated 23 loci significantly associated with an increased risk of developing MM that explain ~16% of heritability [7] and only a subset of familial cases are thought to have a polygenic background [8]. Recent studies have identified rare germline variants predisposing to MM in KDM1A [9], ARID1A and USP45 [10], and the implementation of next-generation sequencing technology will allow the characterization of more such rare variants.

Rendre les cancers évitables. Recherches sur le travail cancérogÚne et ses conséquences
International audienceFrance now counts nearly 400,000 new cancer cases per year. Yet, even though this epidemic is shaped by strong inequalities, the role of work as a cause of cancer remains underacknowledged, if not ignored. In the GISCOP 84 cohort study on blood cancer patients taken care of at Avignon Central Hospital, each cancer is considered as a "sentinel event" giving access to the patientsâ past (and present) occupational exposures to carcinogens, as well as to the obstacles to â and levers of action for â the prevention of occupational cancers and their compensation as occupational diseases. This article presents the GISCOP approach and the type of knowledge it produces. It also analyzes the institutional resistances this action research encounters. Indeed, although the ongoing cancer epidemic is a major public-health crisis requiring a strong response, the prevention of occupational cancers is intricately related to social relations of production â and thus politically sensitive.Avec prĂšs de 400 000 nouveaux cas par an, la France est en pleine Ă©pidĂ©mie de cancer. Or, malgrĂ© la nature fortement inĂ©galitaire de cette Ă©pidĂ©mie, le rĂŽle du travail dans la survenue des cancers demeure peu ou pas pris en compte. Dans le cadre de lâenquĂȘte de cohorte du GISCOP 84 auprĂšs de patients atteints de cancer hĂ©matologique pris en charge au centre hospitalier dâAvignon, chaque cancer est considĂ©rĂ© comme un « Ă©vĂ©nement-sentinelle » donnant accĂšs aux expositions professionnelles aux cancĂ©rogĂšnes subies par les patients, mais aussi aux freins et leviers dâaction pour la reconnaissance en maladie professionnelle et la prĂ©vention. Lâarticle prĂ©sente cette dĂ©marche de recherche pour lâaction et le type de connaissances quâelle permet de produire, tout en analysant les rĂ©sistances institutionnelles auxquelles elle se heurte. En effet, si la crise sanitaire majeure quâest lâĂ©pidĂ©mie de cancers appelle des rĂ©ponses fortes, la prĂ©vention des cancers professionnels est en prise directe avec les rapports sociaux de production â et donc politiquement sensible
Poly-exposition aux cancĂ©rogĂšnes et reconnaissance en maladie professionnelle : le cas des patients atteints de lymphome non hodgkinien. Premiers rĂ©sultats de lâenquĂȘte GISCOP 84
International audienceAlors que les constats dâune sous-reconnaissance massive et structurelle des cancers dâorigine professionnelle se multiplient, le nombre de cancers reconnus en maladies professionnelles baisse. Dans ce contexte, cet article prĂ©sente les premiers rĂ©sultats de lâenquĂȘte du groupement dâintĂ©rĂȘt scientifique sur les cancers dâorigine professionnelle dans le Vaucluse (GISCOP 84) auprĂšs de patients atteints dâhĂ©mopathies malignes. Ces rĂ©sultats soulignent lâimportance, y compris rĂ©cente, de la poly-exposition aux cancĂ©rogĂšnes dans lesactivitĂ©s de travail, ainsi que les obstacles persistants rencontrĂ©s par les patients dans lâaccĂšs au droit Ă rĂ©paration. Cet article montre comment une dĂ©marche de recherche-action pluriprofessionnelle arrive Ă partiellement briser lâinvisibilitĂ© des cancers professionnels et discute lâinadaptation â et les Ă©volutions possibles â du systĂšme de reconnaissance actuel
