RESUMO

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.

RESUMO

BACKGROUND: Long-term visit-to-visit glycemic variability is an additional measure of glycemic control. We aimed to evaluate the prognostic value of several measures of glycemic variability for the occurrence of micro- and macrovascular complications, and all-cause mortality in patients with type 2 diabetes. METHODS: 654 individuals were followed-up over a median of 9.3 years. Glycemic variability (SDs and coefficients of variation of HbA1c and fasting glycaemia) was measured during the first 12- and 24-months. Multivariate Cox analysis, adjusted for risk factors and mean HbA1c and fasting glycaemia levels, examined the associations between glycemic variability and the occurrence of microvascular (retinopathy, microalbuminuria, renal function deterioration, peripheral neuropathy) and macrovascular complications [total cardiovascular events (CVE), major adverse CVEs (MACE) and cardiovascular mortality], and of all-cause mortality. RESULTS: During follow-up, 128 patients had a CVE (96 MACE), and 158 patients died (67 from cardiovascular diseases); 152 newly-developed or worsened diabetic retinopathy, 183 achieved the renal composite outcome (89 newly developed microalbuminuria and 91 deteriorated renal function), and 96 newly-developed or worsened peripheral neuropathy. Glycemic variability, particularly the 24-month parameters either estimated by HbA1c or by fasting glycemia, predicted all endpoints, except for retinopathy and peripheral neuropathy development/progression, and was a better predictor than mean HbA1c. Glycemic variability predicted retinopathy development/progression in patients with good glycemic control (HbA1c ≤ 7.5%, 58 mmol/mol) and predicted new-incident peripheral neuropathy. CONCLUSIONS: Long-term visit-to-visit glycemic variability is an additional and frequently a better glycemic parameter than mean HbA1c levels for assessing the risk of future development of micro- and macrovascular complications in patients with type 2 diabetes.

RESUMO

BACKGROUND: Our aim was to evaluate whether the cell of origin (COO) as defined by the Hans algorithm and MYC/BCL2 coexpression, which are the two main biological risk factors in elderly patients treated with rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine, and prednisolone (R-CHOP), maintain their prognostic value in a large prospective clinical trial. PATIENTS AND METHODS: We evaluated 285 paraffin-embedded samples from patients (60-80 years of age) enrolled in the Lymphoma Study Association trial LNH03-6B who were treated with R-CHOP. We correlated the COO defined by the transcriptome according to the Wright algorithm with that defined by the Hans algorithm in a subset of 62 tumors with available frozen tissue samples. RESULTS: The non-germinal center B-cell-like phenotype according to the Hans algorithm and BCL2 expression (but not MYC and BCL2 coexpression) predicted worse progression-free survival [hazard ratio (HR)=1.78, P = 0.003 and HR = 1.79, P = 0.003, respectively] and overall survival (HR = 1.85, P = 0.005 and HR = 1.67, P = 0.02, respectively) independently of the International Prognostic Index. The correlation between the Hans algorithm and the Wright algorithm was 91%, with an almost perfect concordance according to a kappa test (0.81). CONCLUSIONS: Our results suggest that immunohistochemically defined COO remains a useful tool for predicting prognosis in diffuse large B-cell lymphoma when performed under optimized standardized conditions and that BCL2 expression may help to identify elderly patients at risk for relapse and who could potentially respond to anti-BCL2 targeted agents. In this prospective phase III trial, the coexpression of MYC and BCL2 does not appear to predict worse survival. CLINICAL TRIAL NUMBER: NCT00144755.

RESUMO

In recent years, the number of approved and investigational agents that can be safely administered for the treatment of lymphoma patients for a prolonged period of time has substantially increased. Many of these novel agents are evaluated in early-phase clinical trials in patients with a wide range of malignancies, including solid tumors and lymphoma. Furthermore, with the advances in genome sequencing, new "basket" clinical trial designs have emerged that select patients based on the presence of specific genetic alterations across different types of solid tumors and lymphoma. The standard response criteria currently in use for lymphoma are the Lugano Criteria which are based on [18F]2-fluoro-2-deoxy-D-glucose positron emission tomography or bidimensional tumor measurements on computerized tomography scans. These differ from the RECIST criteria used in solid tumors, which use unidimensional measurements. The RECIL group hypothesized that single-dimension measurement could be used to assess response to therapy in lymphoma patients, producing results similar to the standard criteria. We tested this hypothesis by analyzing 47 828 imaging measurements from 2983 individual adult and pediatric lymphoma patients enrolled on 10 multicenter clinical trials and developed new lymphoma response criteria (RECIL 2017). We demonstrate that assessment of tumor burden in lymphoma clinical trials can use the sum of longest diameters of a maximum of three target lesions. Furthermore, we introduced a new provisional category of a minor response. We also clarified response assessment in patients receiving novel immune therapy and targeted agents that generate unique imaging situations.

RESUMO

Optimal salvage chemotherapy regimen for patients with relapsed or refractory Hodgkin and non-Hodgkin lymphoma remains unclear but often based on platinum regimens. This retrospective study assesses in real life the toxicities profiles of patients with relapsed or refractory lymphoma treated with DHA (dexamethasone, high dose aracytine cytarabine) plus platinum salt (dexamethasone-High dose aracytine (cis)platin (DHAP), dexamethasone-High dose aracytine carboplatin (DHAC), or dexamethasone-High dose aracytine Oxaliplatin (DHAOX)), from February 2007 to May 2013 in 2 French hospitals. Toxicities were recorded from medical files and assessed according to the National Cancer Institute Common Toxicity Criteria version 3.0. Potential risk factors of renal insufficiency were tested by univariate analyses. A total of 276 patients were treated: 168 with DHAP (60.9%), 79 with DHAOX (28.6%), and 29 with DHAC (10.5%). Rituximab was associated in 80.1% of patients (n = 221). Renal failure was reported in 97 patients, mainly with cisplatin regimen (86.6%) leading to 8.9% grade III to IV renal failure (P = .001). Renal insufficiency was reversible in most patients but remained persistent in 24, with all of them being treated with DHAP except 1. Cisplatin-based regimen (50.0% versus 12.0%, P < .05) and female (44.6% versus 29.7%, P < .05) appeared to be at higher risks of renal failure. Platinum cumulative dose is a significant risk factor of nephrotoxicity. Hematologic toxicity was more frequent with carboplatin and cisplatin with at least 1 event (all toxicity grade) respectively in 79.3% and 71.4% of patients treated (P < .005). Auditory toxicity was mainly reported with cisplatin (n = 19; 4 grade I-II and 15 grade III-IV). Oxaliplatin was implicated in 77.6% of neurotoxicity (n = 59), mainly moderate (grade I-II). In conclusion, DHAOX and DHAC regimens have more favorable toxicity profile than DHAP regimen. Their lack of renal toxicity makes them attractive regimens, which may be interesting for patients eligible for autologous stem cell transplantation. Nevertheless, these results have to be confirmed by the therapeutic efficacy of these 3 regimens.

RESUMO

BACKGROUND: Addition of the anti-CD20 monoclonal antibody rituximab to chemotherapy improves response rates and survival in patients with B-cell non-Hodgkin lymphoma (NHL). However, rituximab induces a transient B-cell depletion and a dose-dependent T-cell inactivation that could impair T-cell immunosurveillance. The impact of rituximab on second primary malignancy (SPM) risk remains unclear so far. We thus carried out a systematic review to compare SPM risk among patients treated or not with rituximab. PATIENTS AND METHODS: We retrieved trials from MEDLINE and EMBASE and updated data presented at American Society of Hematology and American Society of Clinical Oncology meetings from 1998 to 2013. We selected randomized, controlled trials addressing newly or relapsed/progressive B-cell NHL in which randomization arms differed only from rituximab administration. Two authors extracted data and assessed the study quality. RESULTS: We analyzed nine trials involving 4621 patients. At a median follow-up of 73 months, a total of 169 SPMs were observed in patients randomized to rituximab compared with 165 SPMs in patients not randomized to rituximab (OR = 0.88; 95% CI 0.66-1.19). The proportion of females, histology subtypes, use of rituximab in first line or in maintenance did not influence SPM risk (P = 0.94, P = 0.80, P = 0.87, P = 0.87, respectively). Cumulative exposure through prolonged administration in trials with rituximab maintenance did not contribute to an increased risk of SPM (P = 0.86). CONCLUSION: Our meta-analysis suggests no SPM predisposition among NHL survivors exposed to rituximab at a median follow-up of 6 years.

RESUMO

BACKGROUND: Angiotensin-converting enzyme (ACE) downregulates the activity of bradykinin, a potent proinflammatory and immunostimulatory peptide liberated from an internal portion of kininogens. Here, we asked whether periodontitis is worsened in patients under antihypertensive treatment with ACE inhibitors. METHODS: Periodontal parameters were recorded from 30 individuals taking ACE inhibitors (case) and 35 taking a non-ACE inhibitor medication (control). Data were analyzed by nonparametric and parametric statistical tests. RESULTS: Most sociodemographic figures were similar in both groups. However, family income was statistically higher in the control group, and the percentage of sites with visible plaque (PL) was statistically higher in the case group (P = 0.043 and P = 0.005, respectively). The prevalence of individuals with chronic periodontitis varied from 31.5% in the control group to 63.4% in the case group (P = 0.001). Patients in the case group presented a 3.2-fold higher risk of having sites with pocket depth ≥5 mm and a 2.9-fold higher risk of having sites with clinical attachment loss ≥5 mm in comparison with those in the control group (P = 0.009 and P = 0.001, respectively; adjusted for family income and visible PL). CONCLUSION: Angiotensin-converting enzyme inhibitors may increase the prevalence and extent of chronic periodontitis in Brazilian patients.

RESUMO

Tailoring treatment by patient strata based on the risk of disease progression and treatment toxicity might improve outcomes of patients with posttransplant lymphoproliferative disorder (PTLD). We analysed the cohort of 70 patients treated in the international, multicenter phase II PTLD-1 trial (NCT01458548) to identify such factors. Of the previously published scoring systems in PTLD, the international prognostic index (IPI), the PTLD prognostic index and the Ghobrial score were predictive for overall survival. None of the scoring systems had a considerable effect on the risk for disease progression. Age and ECOG performance status were the baseline variables with the highest prognostic impact in the different scoring systems. Baseline variables not included in the scoring systems that had an impact on overall survival and disease progression were the type of transplant and the response to rituximab at interim staging. Thoracic organ transplant recipients who did not respond to rituximab monotherapy were at particularly high risk for death from disease progression with subsequent CHOP-based chemotherapy. Patients in complete remission after four courses of rituximab and patients in partial remission with low-risk IPI had a low risk of disease progression. We speculate that chemotherapy might not be necessary in this patient cohort.

RESUMO

WHAT IS KNOWN AND OBJECTIVES: In cancer care, clinical pharmacists contribute to improving prevention and management of drug-related problems (DRPs). The 3-year EPICC study (Evaluation of Pharmaceutical Intervention in Cancer Care) aimed to collect and analyse pharmaceutical interventions (PIs) in oncology. METHODS: The free online version of the French Society of Clinical Pharmacy (SFPC) coding system, ACT-IP, was used, supplemented by a standardized dedicated cancer-care decision tree. RESULTS: A total of 29,589 medication orders (77,004 anticancer drug preparations) were analysed. Eight hundred and ninety-four PIs were recorded. ACT-IP identified 54·1% of DRPs as concerning over- or underdosage. The standardized dedicated cancer-care decision tree identified the three principal causes of dosage problems: 50·2% due to miscalculation, 20% to omission of dose adjustment and 12% to poor choice of antineoplastic regimen. About 13·8% of DRPs were adverse effects and 3·9% were drug-drug interactions. The decision tree showed that 22% of adverse events could be circumvented by a switch within the same drug family and 72% of drug-drug interactions would have led to increased neoplastic toxicity. DISCUSSION: Pharmaceutical analysis of prescription forms contributes to medication safety in cancer care, and the present dedicated decision tree highlights additional information about DRPs and PIs. The DRP rate (3% of prescriptions) was consistent with the literature. The pharmacist has a role to play in optimizing the management of patients with cancer in terms of dose adjustment, drug toxicity management, improvement of administration and drug-drug interactions. WHAT IS NEW AND CONCLUSION: This study, highlighting PIs in cancer care, is the first of this scale in terms of number of prescriptions analysed (nearly 30 000). Results demonstrated the specificity of DRPs and PIs for patients with cancer and the value of a dedicated coding system in cancer care.

RESUMO

Hematopoietic stem cells (HSCs) required to perform peripheral hematopoietic autologous stem cell transplantation (APBSCT) can be collected by processing several blood volumes (BVs) in leukapheresis sessions. However, this may cause granulocyte harvest in graft and decrease in patient's platelet blood level. Both consequences may induce disturbances in patient. One apheresis team's current purpose is to improve HSC collection by increasing HSC collection and prevent increase in granulocyte and platelet harvests. Before improving HSC collection it seemed important to know more about the way to harvest these types of cells. The purpose of our study was to develop a simple model for analysing respective collections of intended CD34+ cells among HSC (designated here as HSC) and harvests of unintended platelets or granulocytes among mature cells (designated here as mature cells) considering the number of BVs processed and factors likely to influence cell collection or harvest. For this, we processed 1, 2 and 3 BVs in 59 leukapheresis sessions and analysed corresponding collections and harvests with a referent device (COBE Spectra). First we analysed the amounts of HSC collected and mature cells harvested and second the evolution of the respective shares of HSC and mature cells collected or harvested throughout the BV processes. HSC collections and mature cell harvests increased globally (p<0.0001) and their respective shares remained stable throughout the BV processes (p non-significant). We analysed the role of intrinsic (patient's features) and extrinsic (features before starting leukapheresis sessions) factors in collections and harvests, which showed that only pre-leukapheresis blood levels (CD34+cells and platelets) influenced both cell collections and harvests (CD34+cells and platelets) (p<0.001) and shares of HSC collections and mature unintended cells harvests (p<0.001) throughout the BV processes. Altogether, our results suggested that the main factors likely to influence intended HSC collections or unintended mature cell harvests were pre-leukapheresis blood cell levels. Our model was meant to assist apheresis teams in analysing shares of HSC collected and mature cells harvested with new devices or with new types of HSC mobilization.

RESUMO

BACKGROUND: Lymphoma occurring in patients aged 90 or older is not uncommon, and its incidence is expected to increase over time. Management of these patients is difficult given their underlying fragility and the lack of information regarding this population. PATIENTS AND METHODS: We retrospectively analyzed 234 patients diagnosed with lymphoma at the age of 90 years or older (90+) between 1990 and 2012 to describe their characteristics, management, outcomes and prognostic factors. RESULTS: The median age was 92 years; 88% were B-cell lymphomas consisting mainly in diffuse large B-cell lymphoma. The median overall survival (OS) was 7.2 months (range, 0-92 months) for the 227 patients with non-Hodgkin Lymphoma (NHL), with a significant difference between aggressive and indolent NHL (5.2 months versus 19.4 months, respectively). We further analyzed 166 NHL patients for whom detailed characteristics were available. Among these patients, 63.5% received a treatment, either local (7.5%) or systemic (56%). Lymphoma was reported as the main cause of death (40%). Treatment administration was associated with improved OS in patients with aggressive (P < 0.001) but not indolent NHL (P = 0.96). In patients with aggressive NHL, hypoalbuminemia appeared as a strong and independent negative prognostic factor. CONCLUSIONS: The median OS is short in 90+ patients diagnosed with lymphoma but some patients experience prolonged survival. Lymphoma represents the main cause of death in these patients. Treatment may improve survival of selected patients with aggressive but not indolent NHL. Management of these patients may be guided by prognostic factors identified in this study, notably serum albumin.

RESUMO

Mucosa-associated lymphoid tissue (MALT) lymphomas most frequently involve the gastrointestinal tract and are the most common subset of extranodal non-Hodgkin lymphoma (NHL). Here we describe overexpression of BCL10, a novel apoptotic signalling gene that encodes an amino-terminal caspase recruitment domain (CARD), in MALT lymphomas due to the recurrent t(1;14)(p22;q32). BCL10 cDNAs from t(1;14)-positive MALT tumours contained a variety of mutations, most resulting in truncations either in or carboxy terminal to the CARD. Wild-type BCL10 activated NF-kappaB but induced apoptosis of MCF7 and 293 cells. CARD-truncation mutants were unable to induce cell death or activate NF-kappaB, whereas mutants with C-terminal truncations retained NF-kappaB activation but did not induce apoptosis. Mutant BCL10 overexpression might have a twofold lymphomagenic effect: loss of BCL10 pro-apoptosis may confer a survival advantage to MALT B-cells, and constitutive NF-kappaB activation may provide both anti-apoptotic and proliferative signals mediated via its transcriptional targets.

RESUMO

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.

RESUMO

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.

RESUMO

AIMS: Gestational diabetes mellitus may precede development of Type 2 diabetes and may be related to cardiovascular disease. Pulse wave velocity measurement is the gold-standard method to evaluate arterial stiffness, a preclinical cardiovascular risk marker. However, the relationship between aortic stiffness and gestational diabetes is unclear. The aim of this study was to evaluate aortic pulse wave velocity in women with gestational diabetes in comparison with a matched control group of healthy pregnant women. METHODS: This case-control study included 24 women with gestational diabetes and 27 matched control subjects. Clinical, demographic and laboratory variables were obtained and aortic pulse wave velocity were measured. RESULTS: Both groups had similar age, gestational age, BMI, ethnicity, smoking status and blood pressure levels. Women with gestational diabetes had aortic pulse wave velocity comparable with control subjects: 7.2 ± 0.9 vs. 7.3 ± 1.2 m/s (P = 0.79). When categorized according to the median value of pulse wave velocity (7.3 m/s), age (P < 0.001), diastolic blood pressure (P = 0.03) and heart rate (P = 0.02) were associated with increased arterial stiffness. In the group with gestational diabetes, there was a non-significant trend towards higher 1-h postprandial glycaemia in patients with higher (above the median) pulse wave velocity (6.5 ± 0.8 vs. 7.1 ± 1.3 mmol/l, P = 0.22) and a lower prevalence of patients with good glycaemic control (38.5 vs. 72.7%, P = 0.09). CONCLUSIONS: Although gestational diabetes may be a risk factor for development of cardiovascular disease, women with gestational diabetes do not have higher aortic stiffness than healthy pregnant women. Time of exposure to hyperglycaemia may have been insufficient to increase central arterial stiffness in women with gestational diabetes.

RESUMO

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.
