Recognition of radiographers in the workplace: Why it matters.

INTRODUCTION: Recognition of radiographers' work has received limited research attention to date, notably its link with wellbeing at work (i.e., job and career satisfaction) and emotional exhaustion. This research focuses on these links and examines more precisely the mediational psychological mechanism (i.e., professional identification) that could explain these relationships. METHODS: This was a cross-sectional, quantitative study with data obtained through an online survey. The sample comprised 713 radiographers working in France. Structural equation modeling was used to test the mediational model. RESULTS: Results of structural equation analysis suggest that radiographers who perceive more professional recognition from their supervisors, colleagues and patients are those who identify most with their profession and who are most satisfied by their job and their career; they also show lower levels of emotional exhaustion. These results underline the crucial role of recognition in the workplace for these professionals. CONCLUSION: Recognition is one of the basic needs of an individual, and satisfying this need is a crucial issue for organizations. This paper focuses on the importance of recognition for radiographers, notably to protect their psychological health and increase their well-being at work and in their professional career. PRACTICAL IMPLICATIONS: Health organizations and supervisors should be aware of the importance of recognizing radiographers' work in order to improve their psychological health, enhance their perceived quality of life at work, and have a positive perception of their career and their work.

[North-South cooperation on transfusion and hematology teaching: A Benin experience]. / Coopération Nord-Sud pour le renforcement des capacités du personnel de santé en hématologie et transfusion : expérience du Bénin.

Hematologic diseases are a significant part of health disorders in Benin. As an example, anemia is the second cause of hospitalization, measuring up to 7.9% all over the country (National Plan of Sanitary Development, 2009-2018). By contrast, there is only one active hematologist in the country. Thanks to two partnerships, on one hand between the health sciences faculty in Cotonou (Benin) and the medicine one in Tours (France), and on the other hand between the Beninese Blood Transfusion National Agency and the French Blood Establishment, a first blood transfusion and hematology formation was held in Cotonou on December 2014. Among other benefits, was created an hematology-transfusion network in order to facilitate relations between Beninese hospital doctors, with the support of the two French partner institutions. The article describes this progress.

The impact of total body irradiation on the outcome of patients with follicular lymphoma treated with autologous stem-cell transplantation in the modern era: a retrospective study of the EBMT Lymphoma Working Party.

BACKGROUND: The aim of this study was to investigate the impact of the high-dose regimen on the outcome of patients with follicular lymphoma (FL) having had autologous stem-cell transplantation (ASCT) in a recent time period. PATIENTS: Between 1995 and 2007, 2233 patients with FL had their first ASCT with either a total body irradiation (TBI)-containing regimen or carmustin, etoposide, cytarabine and melphalan (BEAM), of which 47% were autografted in first remission. RESULTS: After a median observation time of 73 months (interquartile range 30-107), 5- and 10-year non-relapse mortality (NRM) was similar (6% and 10% in both groups). No significant NRM differences became evident after multivariate adjustment for confounders. Secondary malignancies were observed in 9.7% and 7.9% of the patients after TBI and BEAM (P = 0.19), which were treatment-related myelodysplastic syndromes/acute myelogenous leukaemia (t-MDS/AML) in 3.4% and 2.8% (P = 0.57). The median time to t-MDS/AML was around 50 months in both groups. Because of a lower relapse incidence, TBI was associated with better event-free survival reaching statistical significance in the patients transplanted in first remission but not in those transplanted beyond first remission. CONCLUSIONS: In patients with FL who received TBI-based ASCT after 1995 increased NRM and t-MDS/AML risks did not emerge compared with BEAM while disease control was at least equivalent.

The outcome of reduced intensity allogeneic stem cell transplantation and autologous stem cell transplantation when performed as a first transplant strategy in relapsed follicular lymphoma: an analysis from the Lymphoma Working Party of the EBMT.

Both auto-SCT and reduced intensity allo-SCT (RIST) are employed in the treatment of relapsed follicular lymphoma (FL). We have analysed the outcome of these two transplant procedures when used as a first transplant in this setting. We conducted a retrospective comparison of 726 patients who underwent an auto-SCT and 149 who underwent a RIST as a first transplant procedure for relapsed FL as reported to the Lymphoma Working Party of the European Bone Marrow Transplant. The non-relapse mortality (NRM) was significantly worse for patients undergoing a RIST (relative risk (RR) 4.0, P<0.001). The 1-year NRM was 15% for those undergoing a RIST compared with 3% for those undergoing an auto-SCT. Disease relapse or progression were significantly worse for those receiving an auto-SCT (RR 3.1, P<0.001). Patients undergoing a RIST had a 5-year relapse rate of 20% compared with 47% for those undergoing an auto-SCT. The PFS at 5 years was 57% for patients receiving a RIST compared with 48% for those receiving an auto-SCT. There was no significant difference in OS between the two groups. RIST is associated with a higher NRM and lower relapse rate in patients with relapsed FL.

Rituximab induction immunotherapy for first-line low-tumor-burden follicular lymphoma: survival analyses with 7-year follow-up.

BACKGROUND: The purpose of this study was to report long-term results of rituximab induction monotherapy in patients with low-tumor-burden follicular lymphoma (LTBFL). PATIENTS AND METHODS: Of 49 first-line LTBFL patients who received weekly doses of rituximab (375 mg/m(2)), 46 have been followed with a long-term analysis of clinical and molecular responses. RESULTS: Best clinical response (at any staging within a year following treatment) was 80%, 24 (52%) patients had complete or unconfirmed complete response, 13 (28%) had partial response and 9 (20%) had stable or progressive disease. Of 31 patients having a positive bcl2-JH rearrangement, 15 (48%) became negative following treatment. After 83.9 months of follow-up (95% confidence interval 6.4-92.8 months), the median progression-free survival is 23.5 months and overall survival (OS) is 91.7%. Five patients died (one progression, one myelodysplasia, one diffuse large B-cell lymphoma and two solid tumors). Seven patients (15%) are progression-free including five who are bcl2 informative. No unexpected long-term adverse event has been observed. CONCLUSION: A significant proportion of patients remain progression-free 7 years after a single 4-dose rituximab treatment in first-line LTBFL. The 7-year overall survivalOS is very high in this selected population of patients.

A 4-weekly course of rituximab is safe and improves tumor control for patients with minimal residual disease persisting 3 months after autologous hematopoietic stem-cell transplantation: results of a prospective multicenter phase II study in patients with follicular lymphoma.

BACKGROUND: This study explored the efficacy and safety of rituximab as treatment of clinical or molecular residual disease after autologous stem-cell transplantation (ASCT) in follicular lymphoma (FL). PATIENTS AND METHODS: Forty patients with CD20+ FL and clinically (group A, n = 14) or clono-specific PCR-detectable (group B, n = 25) residual disease persisting 3 months after ASCT received rituximab 375 mg/m² once weekly for 4 weeks. RESULTS: Response rate at day 50 was 36% [90% confidence interval (CI) 15-61] in group A (World Health Organization criteria) and 52% (90% CI 34-70) in group B (conversion PCR-undetectable status to undetectable status). The best response rate was 71% [nine complete responses (CRs) and one partial response] in group A and 76% in group B. At 36 months, all 10 responses persisted in group A, whereas 46% of patients in group B still had PCR-undetectable disease. Furthermore, 68% of patients in group B were still in clinical CR. Rituximab after ASCT was safe with few grade 3-4 toxic effects (15% patients), mainly acute reactions and infections. CONCLUSION: Rituximab induced a high rate of durable CRs in patients with clinically detectable disease, as well as durable eradication of PCR-detectable disease in patients with FL after ASCT. Continued molecular responses assessed with a highly sensitive and clono-specific PCR technique were correlated with an excellent disease control.

Autologous transplantation in CLL patients with B and C Binet stages: final results of the prospective randomized GOELAMS LLC 98 trial.

The relevance of high-dose chemotherapy followed by auto-SCT in CLL remains to be defined. The aim of the prospective, randomized, GOELAMS LLC 98 trial was to compare two strategies in previously untreated CLL patients aged <60 years. Conventional chemotherapy (Arm A) consisted of six monthly courses of CHOP followed by six CHOP courses in every 3 months in those achieving a complete or PR. Arm A was compared with high-dose therapy with auto-SCT (Arm B), used as consolidation after three CHOP courses in case of CR or very good PR. A total of 86 patients were enrolled, of which 39 and 43 patients were evaluable in arm A and arm B, respectively. The primary endpoint was PFS. On an intent-to-treat basis and with a median follow-up time of 77.1 (range 1-135.5) months, the median PFS was 22 months in Arm A and 53 months in Arm B (P<0.0001). Median survival time was 104.7 months in arm A and 107.4 months in arm B. This trial demonstrates that frontline high-dose therapy with auto-SCT prolongs PFS but does not translate into a survival advantage in advanced CLL patients in the pre-rituximab era.

[Setting up supportive care in oncology: reflexions and suggestions.]. / A propos de la mise en place des soins de support en cancérologie : pistes de réflexions et propositions.

A group of 19 health professionals implicated in supportive care wanted to suggest some reflexions for organization, setting and evaluation of the supportive care in institutions and health territories. The suggested organization must be applicable to any cancer patient and the place of the care whatever the age, the stage of the disease; in the future, must be applicable to any patient with serious chronic illness. This organization must allow to optimize the accompaniment and the care of the patients and their close relations by 1) precise and regular analysis of their needs; 2) the respect of the continuity of the health care; 3) the setting of collaborative practice and transversality in the care. It is not a new medical speciality but a coordination of competences for patients and their families.

On the use of lonafarnib in myelodysplastic syndrome and chronic myelomonocytic leukemia.

Lonafarnib is an orally bio-available farnesyltransferase inhibitor that prevents farnesylation of specific target proteins including Ras. In a multicenter study, 67 patients with advanced myelodysplastic syndrome (MDS) and chronic myelomonocytic leukemia (CMML) were treated with a continuous oral dose of 200-300 mg of lonafarnib and were evaluated for hematologic, pathologic and pharmacodynamic response. The median age of patients was 70 years (range 44-86). There were 32 patients with MDS (RAEB-20 and RAEB-t-12) and 35 with CMML. Overall 16 (24%) of the patients responded with two patients achieving a complete remission and one a partial response. Responses were seen in 6/32 and 10/35 patients with MDS and CMML, respectively. Of the 19 patients who were platelet transfusion-dependent prior to treatment, 5 (26%) became transfusion-free for a median duration of 185 days. A decrease in the farnesylation of the HDJ-2 protein measured in patient-derived cells was observed in the majority of patients during treatment with lonafarnib, but no clear correlation between changes in farnesylation and clinical effect could be made. Gastrointestinal toxicity was significant with 19% of patients discontinuing therapy due to diarrhea, nausea and/or anorexia. Lonafarnib has demonstrable activity in patients with advanced MDS and CMML.

Neutrophil role in in vivo anti-lymphoma activity of rituximab: FCGR3B-NA1/NA2 polymorphism does not influence response and survival after rituximab treatment.

BACKGROUND: Neutrophils could play an important role in in vivo rituximab anti-lymphoma activity. FcgammaRIIIb is expressed only by neutrophils and FcgammaRIIIb-neutrophil antigen (NA)1/NA2 polymorphism influenced phagocytosis of immunoglobulin G1-opsonized particles. We formulated the hypothesis that if neutrophils are critical cells for in vivo rituximab activity, FcgammaRIIIb-NA1/NA2 polymorphism could influence the response to rituximab. PATIENTS AND METHODS: FCGR3B-NA1/NA2 genotypes were determined in 46 patients having received rituximab for a previously untreated, follicular, non-Hodgkin's lymphoma. The clinical response and the disappearance of the BCL2-JH gene rearrangement in both peripheral blood and bone marrow were evaluated at 2 months (M2) and each year during 7 years. RESULTS: They were 13% homozygous for FCGR3B-NA1, 61% homozygous for FCGR3B-NA1/NA2 and 26% heterozygous. The objective response rates at M2 were 67% in homozygous FCGR3B-NA1 patients compared with 75% in homozygous FCGR3B-NA2 and 75% in heterozygous patients (not significant). We found no difference for progression-free and overall survival by FCGR3B-NA1/NA2 genotypes. CONCLUSION: These results indicate no association between FCGR3B-NA1/NA2 polymorphism and response to rituximab indicating no significant role of phagocytosis mediated by neutrophils in in vivo mechanism of rituximab activity.

[Health care units in the French blood banks, why?]. / Les structures de soins dans les établissements de transfusion sanguine, pourquoi faire ?

In France for several years, many patients have been treated in Blood Transfusion Centers belonging to the EFS. This partnership between public hospitals and EFS is appreciated by the patients who find a competent staff in transfusion and apheresis process, in a more pleasant environment than in hospital. There is a total of 93 Health Care Units in Blood Transfusion Centers. Sixty-three of these Health Care Units perform only transfusions and bleeding. In the remaining 30 Health Care Units apheresis, peripheral blood hematopoietic stem, cell harvesting, plasmatic exchanges and extracorporeal photopheresis are also performed. Despite the perfect fit between hospital needs, comfort and easiness for patients, an economical problem remains. At the present time, the reimbursement rate by national health insurance is below the real cost. If unsolved, this discrepancy could force an end to this beneficial partnership.

Long-term follow-up of a randomized trial of fludarabine-mitoxantrone, compared with cyclophosphamide, doxorubicin, vindesine, prednisone (CHVP), as first-line treatment of elderly patients with advanced, low-grade non-Hodgkin's lymphoma before the era of monoclonal antibodies.

BACKGROUND: This randomized study compared the efficacy and safety of fludarabine-mitoxantrone (FM) with mini-CHVP (cyclophosphamide, doxorubicin, vindesine, prednisone) in elderly patients with advanced, low-grade non-Hodgkin's lymphoma. PATIENTS AND METHODS: End points were remission rates [overall response (OR) and complete response (CR)], failure-free survival (FFS), survival and toxicity. One hundred and fifty-five patients were randomized, 144 were evaluable for safety and 142 for response. Each treatment arm was given as six monthly cycles, followed by three bimonthly cycles. FM comprised fludarabine (20 mg/m(2) i.v.), days 1-5, plus mitoxantrone (10 mg/m(2) i.v.), day 1. CHVP cycles comprised cyclophosphamide (750 mg/m(2) i.v. infusion), doxorubicin (25 mg/m(2) i.v.) and vindesine (3 mg/m(2) i.v.) on day 1, and prednisone (50 mg/m(2)) on days 1-5. RESULTS: FM therapy resulted in superior remission rates (OR 81% versus 64%, CR 49% versus 17%; P = 0.0004). Median FFS for FM patients was 36 months, compared with 19 months for CHVP patients, and has not yet been reached for early CR patients at 53 months. Treatment arm was the major risk factor influencing survival. Both treatments were well tolerated, with only few infectious complications. CONCLUSION: FM was more effective than CHVP in achieving OR and CR, and favorably affected the outcome.

Front-line high-dose therapy with autologous stem cell transplantation for high risk Hodgkin's disease: comparison with combined-modality therapy.

This retrospective study compares high-dose therapy (HDT) with autologous stem cell transplantation and combined-modality treatment (CT) as a first-line therapy for Hodgkin's disease (HD) for patients with both a clinical stage (CS) IV and/or a mediastinal mass > or =0.45 of the thoracic diameter (MM > or =0.45) at diagnosis, and an incomplete response after the first-line chemotherapy. Data on 42 grafted patients (GP) in Nantes Hospital, France and on 108 combined-modality treated patients (CTP) from two protocols of the GOELAMS group, France (POF 81 and H90) was analyzed. Both groups were comparable except for pulmonary disease in excess in the grafted group (P = 0.01). Among GP, 95% were in complete response at the end of first-line treatment and 77% among CTP. Median follow-up was 53 months (range, 7 to 128 months) for GP and 88 months (range, 25 to 181 months) for CTP. The 5-year freedom from progression (FFP) and event-free survival (EFS) rates were better for GP (87% vs 55% for FFP: P = 0.0004 and 81% vs 51% for EFS: P = 0.0004) whereas the overall survival (OS) rates did not differ significantly (85% for GP vs 71% for CTP: P = 0.06). Similar results were obtained for the groups with a response > or =50% after initial chemotherapy: 91% vs 65% for FFP, P = 0.01; 87% vs 61% for EFS, P = 0.02; and 92% vs 77% for OS, P = 0.2; and for the groups with a response <50%: 80% vs 22% for FFP, P = 0.0003; 72% vs 13% for EFS, P = 0.0001; and 76% vs 46% for OS, P = 0.04. This study shows a better control of the disease with HDT.

Persistent decrease in proliferative potential of marrow CD34(+)cells exposed to early-acting growth factors after autologous bone marrow transplantation.

Post-graft hematopoiesis is characterized by long-term quantitative deficiency in marrow progenitor cells in both autologous and allogenic settings. In order to evaluate the function of post-graft progenitor cells, the proliferative capacity of marrow CD34(+) cells was evaluated in 10 patients 6 months after autologous bone marrow transplantation (ABMT) for non-Hodgkin's lymphoma and compared to that of 10 patients before ABMT and 10 normal controls. Immuno-selected CD34(+) cells were cultured for 7 days in liquid serum-free medium with a combination of early-acting GF consisting of stem cell factor, IL-3 and IL-1beta. Clonogenic efficiency of unselected cells for CFU-GM and BFU-E was decreased in post-graft patients compared to pre-graft and control patients. However, clonogenic efficiency of selected CD34(+) cells for CFU-GM was not different in post-graft, pre-graft and control patients but BFU-E values of post-graft patients remained lower than those of control patients. Decreased percentages of CD34(+) CD38(-) cells were observed in both post-graft and pre-graft patients while those of CD34(+) c-kit(+) cells were similar in all three patient groups. After 7-day liquid culture, expansion yields of total progenitor cells were significantly lower in post-graft patients (147 +/- 28%) than in pre-graft (255 +/- 27%) and control patients (246 +/- 23%). Post-graft deficiency in progenitor cell expansion was particularly marked for BFU-E (61 +/- 24%) compared to pre-graft patients (220 +/- 82%) and to controls (349 +/- 82%). These results indicate impaired proliferative potential of marrow CD34(+) cells several months after ABMT involving erythroid progenitor cells and/or commitment towards erythroid lineage from a more immature stage (pre-CFU).

[Role of high-dose chemotherapy with hemopoietic stem-cell support in the treatment of adult patients with high-grade glioma]. / Place de la chimiothérapie intensive avec autogreffe de cellules souches hématopoïétiques dans le traitement des tumeurs gliales de haut grade chez l'adulte.

Despite surgery, post-operative irradiation and adjuvant conventional chemotherapy, prognosis of high-grade gliomas remains poor. Carmustine (BCNU) has been shown to have limited activity at conventional dosage but is still the standard chemotherapy. Activity of chemotherapy is limited by the blood-brain barrier impermeability and high levels of expression of multidrug resistance proteins on tumor and/or endothelial cells. Despite high response rates, development of intra-arterial chemotherapy remains limited because of frequent acute brain toxicity related to drug administration. High-dose intravenous chemotherapy rescued by autologous hemopoietic stem cell transplantation is an alternative that might increase drug delivery through the blood-brain barrier and tumor control. Several phase I-II trials using high-dose BCNU were published. The maximum tolerated dose seems to be 800 mg/m2 and interstitial pneumonitis and hepatitis are dose-limiting toxicities. Few phase I-II trials of high-dose therapy were published using drug combinations. High response rates in patients with progressive tumor were observed and in adjuvant setting, encouraging results in terms of median survival time and long survivors were published. No phase III trial was reported to date. Future investigations should include randomized trials comparing high-dose and conventional-dose chemotherapy and development of new high-dose regimens that incorporate new drugs such as temozolomide.

Acquired inhibitor to factor VIII in a patient with Hodgkin's disease following treatment with interferon-alpha.

We describe a young woman who developed acquired haemophilia after 18 months of interferon (IFN-)-alpha therapy. This patient had been monitored since 1992 for Hodgkin's disease initially treated by chemotherapy. After two relapses, she received intensive chemotherapy followed by an autologous peripheral progenitor cell graft. IFN-alpha was then administered for 18 months. Bleeding of the limbs and tongue occurred 1 month after withdrawal of IFN-alpha and high titres (123 Bethesda units) of autoantibody to factor VIII (FVIII):C were measured. Prednisone (1 mg kg(-1) day(-1)) achieved rapid cessation of the bleeding and FVIII autoantibodies were undetectable 5 months later. This case report suggests that the activated partial thromboplastin time should be regularly checked in every patient treated with IFN-alpha in cases of unexplained bleeding, together testing for antibodies to FVIII if the bleeding is prolonged.

Continuous infusion of vincristine-doxorubicin with bolus of dexamethasone(VAD) alternated with CHEP in the treatment of patients over 60 years old with aggressive non-Hodgkin's lymphoma.

This prospective study was undertaken to evaluate the efficacy and toxicity of combination chemotherapy with alternating cycles of vincristine, doxorubicin and dexamethasone (VAD) and cyclophophamide, doxorubicin, etoposide and prednisone (CHEP) in patients over 60 years old with previously untreated and advanced non-Hodgkin's lymphoma (NHL) of intermediate- and high-grade malignancy. Eighty one consecutive, patients with NHL referred from April 1992 to October 1997 to GOELAMS centers were enrolled in this study and their outcome updated to June 1, 1999. Of 81 enrolled patients, 77 were eligible and assessable for response. The median age was 70 years (61 to 78), 85.7% were stage III or IV, 39% were of performance status > or = 2, 27.3% > or = 2 involved extra-nodal sites and 57.3% had higher LDH levels than normal. The immunophenotype was B in 87% and T in 13%. Fifty-one (66.2%) patients received the scheduled eight cycles of therapy and treatment was withdrawn in only 6 patients (7.8%) because of toxicity. Neutropenia grade 3-4 occurred in 11.1% after VAD courses vs 40.6% after CHEP courses. The mean cumulative dose of doxorubicin was 269 mg/m2 and the relative dose intensity was 84%. The overall response and complete response rates were 66.2% and 51.9% respectively, and after a median follow-up of 52 months the 3 year overall survival (OS) and event-free survival rates (EFS) were 43.5% and 33.0% respectively. In multivariate analysis, OS and EFS were statistically influenced by IPI (p = 3 x 10(-3); p < 1 x 10(-4)) and phenotype (p = 2 x 10(-3); p < 1 x 10(-4)). Our findings support the alternation of 4 courses of VAD and CHEP as it is well tolerated in patients over 60 years old with advanced intermediate- or high-grade NHL and provides response and survival rates comparable to 6 courses of CHOP.

Association between the SDF1-3'A allele and high levels of CD34(+) progenitor cells mobilized into peripheral blood in humans.

Some patients unexpectedly fail to mobilize sufficient numbers of haematopoietic progenitor cells (HPCs) into the peripheral blood for autologous transplantation. Considering the important role of the chemokine stromal cell-derived factor 1 (SDF-1) in HPC homing, we investigated a possible relationship between SDF1 gene polymorphism and HPC mobilization capacity in 63 patients with malignancy. Some 67% of the good mobilizers (> or = 50 CD34(+) cells/microl) and only 36% of the intermediate/poor mobilizers were SDF1-3'A allele carriers (P = 0.032). In multivariate analysis, the presence of the SDF1-3'A allele was the only factor predictive of good CD34(+) cell mobilization (P = 0.025). This is the first report showing the involvement of genetic factors for HPC mobilization in humans and suggests a significant role for SDF-1 in this process.
