A systematic review of dimensions evaluating patient experience in chronic illness.

BACKGROUND: Living with a chronic disease often means experiencing chronic treatments and regular multidisciplinary monitoring as well as a profound life-changing experience which may impact all aspects of a patients life. The patient experience of chronic disease is frequently assessed by patient reported measures (PRMs) which incorporate patients perspectives to better understand how illness, treatment and care impact the entirety of a patient's life. The purpose of this review was to collect and review different kinds of available PRM instruments validated for chronic patients, to produce an inventory of explored concepts in these questionnaires and to identify and classify all dimensions assessing chronic patients experience. METHODS: A systematic review of PRM instruments validated for chronic patients was conducted from three databases (Medline, the Cochrane library, and Psycinfo). Articles were selected after a double reading and questionnaires were classified according to their targeted concept. Then, all dimensions of the questionnaires were clustered into different categories. RESULTS: 107 primary validation studies of PRM questionnaires were selected. Five kinds of instruments were recorded: 1) Questionnaires assessing health related quality of life or quality of life; 2) Instruments focusing on symptoms and functional status; 3) Instruments exploring patients' feelings and attitude about illness; 4) Questionnaires related to patients' experience of treatment or healthcare; 5) Instruments assessing patients attitudes about treatment or healthcare. Twelve categories of dimensions were obtained from these instruments. CONCLUSIONS: This review provided an overview of some of the dimensions used to explore chronic patient experience. A large PRM diversity exists and none of the reviewed and selected questionnaires covered all identified categories of dimensions of patient experience of chronic disease. Furthermore, the definition of explored concepts varies widely among researchers and complex concepts often lack a clear definition in the reviewed articles. Before attempting to measure chronic patient experience, researchers should construct appropriate instruments focusing on well-defined concepts and dimensions encompassing patient's personal experience, attitude and adaptation to illness, treatment or healthcare.

Minimal residual disease negativity using deep sequencing is a major prognostic factor in multiple myeloma.

The introduction of novel agents has led to major improvements in clinical outcomes for patients with multiple myeloma. To shorten evaluation times for new treatments, health agencies are currently examining minimal residual disease (MRD) as a surrogate end point in clinical trials. We assessed the prognostic value of MRD, measured during maintenance therapy by next-generation sequencing (NGS). MRD negativity was defined as the absence of tumor plasma cell within 1 000 000 bone marrow cells (<10-6). Data were analyzed from a recent clinical trial that evaluated the role of transplantation in newly diagnosed myeloma patients treated with lenalidomide, bortezomib, and dexamethasone (RVD). MRD negativity was achieved at least once during maintenance in 127 patients (25%). At the start of maintenance therapy, MRD was a strong prognostic factor for both progression-free survival (adjusted hazard ratio, 0.22; 95% confidence interval, 0.15-0.34; P < .001) and overall survival (adjusted hazard ratio, 0.24; 95% confidence interval, 0.11-0.54; P = .001). Patients who were MRD negative had a higher probability of prolonged progression-free survival than patients with detectable residual disease, regardless of treatment group (RVD vs transplant), cytogenetic risk profile, or International Staging System disease stage at diagnosis. These results were similar after completion of maintenance therapy. Our findings confirm the value of MRD status, as determined by NGS, as a prognostic biomarker in multiple myeloma, and suggest that this approach could be used to adapt treatment strategies in future clinical trials.

Heavy + light chain analysis to assign myeloma response is analogous to the IMWG response criteria.

Automated serum heavy + light chain (HLC) immunoassays can measure the intact immunoglobulins of each light chain type separately. We though to compare HLC assays with electrophoretic techniques in determining International Myeloma Working Group (IMWG) response criteria. 114 myeloma patients from 2 trials were included. HLC measurements were made utilizing archived sera and response assessments compared with those based on electrophoretic analysis at the time of the trials. Assessments at ∼90 days and maximal response were compared as was the power of the 2 techniques for predicting later responses, overall survival, and progression. The kappa statistic indicated good agreement between the 2 methods for determining IMWG response criteria, although HLC measurements might give better predictions of subsequent responses and frequently gave an earlier indication of change. HLC measurements could represent an alternative to electrophoretic techniques in determining IMWG response. Validation with a greater range of patient responses is needed for confirmation.

FDG PET to Diagnose Neurolymphomatosis in a Case of Triple-Hit B-Cell Lymphoma.

A 46-year-old man with stage IV triple-hit B-cell lymphoma diagnosed in February 2016 was treated with chemotherapy. He was followed classically with FDG PET/CT, which assessed the complete metabolic response in June 2016. In July 2016, he had autologous stem cell transplantation. Two months later, he underwent an FDG PET/CT for revaluation. It showed intense FDG uptake in the medullary canal from cervical 4 to thoracic 4, bilateral cervical 7 to thoracic 8, and right thoracic 9 to 12 nerve roots, leading to the diagnosis of neurolymphomatosis. A clinical cervical radiculopathy and spinal MRI results reinforced this diagnosis.

Trastuzumab for treatment of refractory/relapsed HER2-positive adult B-ALL: results of a phase 2 GRAALL study.

The aim of this phase 2 study was to evaluate the efficacy and safety of trastuzumab, a humanized monoclonal antibody targeted against the human epidermal growth factor receptor 2 (HER2), for adult patients with relapsed/refractory HER2-positive B-ALL. Fifteen patients, with a median age of 62 years, received trastuzumab according to the schedule approved for breast cancer patients (ie, 4 mg/kg intravenous loading dose followed by 2 mg/kg weekly). The overall response rate was 13% with 2 patients achieving partial response and partial remission cytolytic response, respectively. Two other patients were documented with blast clearance. Only 1 reversible grade 3 cardiac toxic event occurred. This phase 2 study showed that trastuzumab monotherapy can allow for some responses in a very high-risk refractory/relapsed HER2-positive adult B-ALL population. Combination of trastuzumab with chemotherapy or other therapeutic monoclonal antibodies should be tested in the future.

Myeloid Sarcoma of the Uterine Cervix as Presentation of Acute Myeloid Leukaemia after Treatment with Low-Dose Radioiodine for Thyroid Cancer: A Case Report and Review of the Literature.

The development of acute myeloid leukaemia after low-dose radioiodine therapy and its presentation as a myeloid sarcoma of the uterine cervix are both rare events. We report a case of acute myeloid leukaemia revealed by a myeloid sarcoma of the uterine cervix in a 48-year-old woman, 17 months after receiving a total dose of 100 mCi (131)I for papillary thyroid cancer. A strict hematological follow-up of patients treated with any dose of (131)I is recommended to accurately detect any hematological complications which might have been underestimated. Unusual presentations, such as chloroma of the uterine cervix, may reveal myeloid malignancy and should be kept in mind.

Factors associated with overall and attributable mortality in invasive aspergillosis.

BACKGROUND: Invasive aspergillosis is associated with high death rates. Factors associated with increased mortality have not yet been identified in a large population of patients with various underlying conditions. METHODS: We retrospectively reviewed 385 cases of suspected or documented aspergillosis that occurred during a 9-year period. We identified 289 episodes that fulfilled the criteria for possible, probable, or proven invasive aspergillosis according to the international definition criteria and that was treated with an anti-Aspergillus active antifungal drug. Clinical and microbiological variables were analyzed for their effects on overall and attributable mortality. Significant variables in univariate analysis were introduced into a multivariate Cox model. RESULTS: Twelve-week overall and disease-specific survival rates were 52.2% (95% confidence interval, 46.5%-57.9%) and 59.8% (95% confidence interval, 54.0%-65.4%), respectively. Receipt of allogeneic hematopoietic stem cell or solid-organ transplant, progression of underlying malignancy, prior respiratory disease, receipt of corticosteroid therapy, renal impairment, low monocyte counts, disseminated aspergillosis, diffuse pulmonary lesions, pleural effusion, and proven or probable (as opposed to possible) aspergillosis are predictors of increased overall mortality. Similar factors are also predictors of increased attributable mortality, with the following exceptions: pleural effusion and low monocyte counts have no impact, whereas neutropenia is associated with a higher attributable mortality. CONCLUSIONS: Identification of predictors of death helps in the identification of patients who could benefit from more-aggressive therapeutic strategies. Initiation of therapy at the stage of possible infection improves outcome, and this finding calls for the development of efficient preemptive strategies to fill the gap between empirical and directed therapy.

[18F]fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography for early evaluation of treatment efficacy in advanced non-Hodgkin lymphoma of uterine corpus: a case report.

We report a case of diffuse large B-cell lymphoma occurring in a patient with the hyperimmunoglobulinemia E syndrome, a rare immune disorder defined by elevated immunoglobulin E levels and recurrent bacterial and fungal infections often manifesting as cold abscesses. This case further supports the notion that patients with hyperimmunoglobulinemia E have an increased risk of lymphoid malignancies and should be closely monitored. Despite a theoretic risk of severe infectious complications, chemotherapy was well tolerated and resulted in a sustained complete remission.

[Lipid formulations of amphotericin B in the management of invasive fungal infections]. / Apports des derives lipidiques de l'amphotéricine B dans la prise en charge des infections fongiques.

Three lipid formulations of amphotericin B have been developed: amphotericin B colloidal dispersion, amphotericin B lipid complex, and liposomal amphotericin B. These three compounds differ by their lipid composition and therefore by their physical characteristics, their pharmacokinetics, and their safety and efficacy profile. There is a consensus to accept reduced toxicity of these formulations, especially reduced, but not absence of, renal toxicity as compared to amphotericin B deoxycholate. Few well-designed studies have been conducted and none of them demonstrated convincingly superiority in term of efficacy of any of the lipid preparations over amphotericin B deoxycholate. Recently a double blind randomized study compared a standard dose of 3 mg/kg/d of liposomal amphotericin B and a loading dose (10 mg/kg/d for 14 days and then the standard dose) in primary therapy of invasive filamentous fungal infections, mainly aspergillosis. Response rate at end of randomized therapy as well as survival at 12 weeks was numerically superior in the standard dose arm but this difference was not statistically significant. Lack of benefit of high dose liposomal amphotericin B in aspergillosis cannot yet be extrapolated to other filamentous fungal infections. Nephrotoxicity was substantially higher in the loading dose arm and this contraindicates its use in clinical practice.

Long-term survival in post-transplant lymphoproliferative disorders with a dose-adjusted ACVBP regimen.

Post-transplant lymphoproliferative disorders (PTLD) are severe complications after solid organ transplantation with no consensus on best treatment practice. Chemotherapy is a therapeutic option with a high response and a significant relapse rate leading to a low long-term tolerance rate. Currently, most centres use anthracycline-based drug combinations, such as CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone). We assessed the efficacy and safety of a dose-adjusted ACVBP (doxorubicin reduced to 50 mg/m(2), cyclophosphamide adjusted to renal function, vindesine, bleomycin, prednisone) regimen in patients failing to respond to a reduction in immunosuppressive therapy. Favourable responses were observed in 24 (73%) of the 33 treated patients. Fourteen (42%) patients died, mostly from PTLD progression. Actuarial survival was 60% at 5 years and 55% at 10 years. Survival prognostic factors were: number of involved sites (P = 0.007), clinical stage III/IV (P = 0.004), bulky tumour (P < 0.0001), B symptoms (P = 0.03), decreased serum albumin (P = 0.03) and poor performance status (P = 0.06). Both the international and the PTLD prognostic index were predictive for survival (P = 0.001 and P = 0.002, respectively). Overall 128 cycles were given. Grade 3 or 4 neutropenia was recorded after 26 (20%) chemotherapy cycles in 19 (58%) patients. Forty-one (32%) infections were recorded in 26 (79%) patients. This study demonstrated that an individual dose-adjustment of ACVBP regimen was manageable in PTLD patients and favourably impacted on long-term survival.

Cytogenetic studies of a series of 43 consecutive secondary myelodysplastic syndromes/acute myeloid leukemias: conventional cytogenetics, FISH, and multiplex FISH.

We report a series of 43 consecutive therapy-related myelodysplastic syndromes (t-MDS) or acute myeloid leukemias (t-AML) observed for 6 years. This series consisted of 26 women and 17 men, ages ranging from 9 to 85 years. These cases were classified into three groups according to the primary diagnosis. Conventional cytogenetic and fluorescent in situ hybridization (FISH)/ multiplex FISH (M-FISH) methods were used to analyze cytogenetic characteristics of secondary MDS/AML. The features of chromosomal abnormalities were linked to the nature of the therapy and protocols used. A considerable proportion of recurrent balanced translocations characterized t-AML secondary to therapy. FISH techniques showed that conventional cytogenetics often underestimated associated translocations; some deletions were in fact derivative chromosomes associated with deletions. After treatment for lymphomas and chronic myeloproliferative diseases, there were more complex unbalanced abnormalities than the control group. Compared to other series, recurrent translocations appeared to be more numerous (25%), probably reflecting an evolution of therapeutic modalities.

Antifungal combination treatment: a future perspective.

The use of antifungal combination therapy is a new clinical approach for combating fungal infections. Although few conclusive clinical studies have been performed to date, data exist that strongly suggest that combination therapy would benefit specific patient subgroups (e.g. stem-cell transplant recipients). This paper examines the evidence available from in vitro, experimental, and clinical studies, and seeks to discover viable clinical strategies for this promising new therapeutic approach.

[Post-therapy surveillance in non-Hodgkin's lymphomas]. / Surveillance post-thérapeutique des lymphomes non hodgkiniens.

Post-treatment surveillance in non-Hodgkin's lymphoma is required for an early diagnosis of a relapse and for the detection of a potential late treatment-related complication. The risk of relapse is highest during the first 2 years in aggressive lymphomas. The risk of relapse decreases then and becomes very low after the 5th year of follow-up. For low-grade lymphomas, the relapse rate remains constant for a longer period and late relapses are more common. Clinical examination and biological tests (blood cell count, lactate dehydrogenase and, in some instance, beta-2-microglobulin serum level determination) are the basis of the surveillance. Radiological and specific tests will be done according to the initial organ involvement. The frequency of the surveillance mainly depends on the histological subtype. Late chemotherapy-related complications include second cancer (solid tumor, myelodysplastic syndrome and acute leukemia), cardiac and endocrine toxicity. Detection of these events also requires close clinical and biological monitoring.
