RESUMO

BACKGROUND: Most patients with multiple myeloma (MM) relapse or become refractory, resulting in high health care costs. However, real-world data regarding the utilization of health care services among the relapsed/refractory MM (RRMM) population are scarce. METHODS: Observational, cross-sectional, multicenter study of the utilization of health care services by RRMM patients who had relapsed within the previous 6 months in Spain in a real-world setting. Data were collected from the clinical records and during a single structured interview and included sociodemographic and clinical characteristics at last relapse, the treatment and health care services nature, and were presented using descriptive statistics. RESULTS: The 276 patients enrolled (53.3% males), with a mean [SD] age of 67.4 [10.5] years, had experienced their most recent relapse a median (IQR) of 1.61 (0.74, 3.14) months before entering the study. Patients lived a median (IQR) of 9.0 (3.0, 30.0) km away from the hospital and visited the hospital a median (IQR) of 3.0 (2.0, 5.0) times/month to receive treatment for their most recent relapse. They spent a median (IQR) of 15.84 (5.0, 42.0) euros/month on transportation. Since their most recent relapse, most patients had been admitted to a hospital unit (n = 155, 56.2%), had required ≥1 diagnostic tests (n = 227, 82.2%), and had consulted the hematologist (n = 270, 97.8%) a mean (SD) of 5.5 (5.4) times. In half of the visits, patients were accompanied by an actively working caregiver (n = 112, 54.4%). CONCLUSIONS: RRMM treatments are associated with a high utilization of health care services and pose a significant burden for patients and caregivers. TRIAL REGISTRATION NUMBER: NCT03188536.

RESUMO

The effectiveness of venetoclax (VEN) in relapsed or refractory acute myeloid leukemia (RR-AML) has not been well established. This retrospective, multicenter, observational database studied the effectiveness of VEN in a cohort of 51 RR-AML patients and evaluated for predictors of response and overall survival (OS). The median age was 68 years, most were at high risk, 61% received ≥2 therapies for AML, 49% had received hypomethylating agents, and ECOG was ≥2 in 52%. Complete remission (CR) rate, including CR with incomplete hematological recovery (CRi), was 12.4%. Additionally, 10.4% experienced partial response (PR). The CR/CRi was higher in combination with azacitidine (AZA; 17.9%) than with decitabine (DEC; 6.7%) and low-dose cytarabine (LDAC; 0%). Mutated NPM1 was associated with increased CR/CRi. Median OS was 104 days (95% CI: 56-151). For the combination with AZA, DEC, and LDAC, median OS was 120 days, 104 days, and 69 days, respectively; p = 0.875. Treatment response and ECOG 0 influenced OS in a multivariate model. A total of 28% of patients required interruption of VEN because of toxicity. Our real-life series describes a marginal probability of CR/CRi and poor OS after VEN-based salvage. Patients included had very poor-risk features and were heavily pretreated. The small percentage of responders did not reach the median OS.

RESUMO

INTRODUCTION: Treatment of relapsed and/or refractory multiple myeloma (RRMM) should be established based on multiple factors, including previous treatment and the sociodemographic/clinical characteristics of the patients. However, patients enrolled in randomized-controlled trials often do not mirror the scenario encountered in real-world practice, thus challenging therapeutic decisions in day-to-day practice. PATIENTS AND METHODS: This observational, cross-sectional, multicenter study aimed to investigate the sociodemographic and clinical characteristics of patients with RRMM treated in routine practice in Spain and their influence on treatment regimens. RESULTS: The study included 276 RRMM patients (median age 69 years; no gender predominance). Seventy-four percent of patients had CRAB features at the time of study inclusion, 65.9% bone lesions, 28.7% high-risk cytogenetics, and 27.0% were at ISS stage III; 65.1% were retired and lived in urban areas (75.7%) with their relatives (85.8%); 28.7% had some dependence degree. Patients had experienced their last relapse in a median of 1.61 months before enrollment and had received a median of 2 treatment lines (range 1-10). Second-and third-line therapies were mostly based on immunomodulatory drugs, followed by proteasome inhibitors (PIs), whereas monoclonal antibodies prevailed in later treatment lines. The presence of extramedullary plasmacytomas, the absence of osteopenia, and being in the second or third treatment line (vs. later lines) significantly increased the odds of receiving PIs. CONCLUSIONS: RRMM treatment in the real-world setting is highly heterogeneous and is primarily influenced by the number of previous lines. The consideration of patients' clinical and sociodemographic characteristics may support clinicians in making therapeutic decisions.

RESUMO

Aim: To describe treatment patterns and outcomes in nontransplant newly diagnosed multiple myeloma (NDMM) patients in Spain. Methods: This retrospective study included two cohorts of NDMM patients diagnosed between 1 January 2012 to 31 December 2013 and 1 April 2016 to 31 March 2017. Results: Among 113 patients, proteasome inhibitor (PI) + alkylator combinations (49%) and PI-based regimens without an alkylator (30%) were the most common first-line (1L) therapies. Use of PI + immunomodulatory drug-based regimens increased between the cohorts; PI-based regimens without an alkylator/immunomodulatory drug decreased. Use of 1L oral regimens was low but increased over time; use of maintenance therapy was low across both periods. Median 1L duration of treatment was 6.9 months. Conclusion: Short 1L duration of treatment and low use of 1L oral regimens and maintenance therapy highlight unmet needs in NDMM.


Lay abstract This study describes treatment patterns and outcomes in newly diagnosed multiple myeloma (NDMM) patients in Spain who were not candidates for transplant. The study looked at two patient groups: patients diagnosed between 1 January 2012 and 31 December 2013 and those diagnosed between 1 April 2016 and 31 March 2017. Among the 113 patients considered, the most common first-line therapies were proteasome inhibitor (PI) + alkylator combinations (49%) and PI-based regimens without an alkylator (30%). We saw increased use of PI with immunomodulators (which arm the immune system to battle disease) and decreased use of PI-based regimens without an alkylator or immunomodulator. First-line use of oral regimens was low but increased over time. The median length of first-line treatment for both groups combined was 6.9 months. Finding low use of first-line oral regimens and maintenance therapy and a short duration of first-line treatment, our study highlights the unmet needs that exist in NDMM patients who are not transplant candidates in Spain.

RESUMO

5-Azacitidine (AZA) therapy is used in high-risk myelodysplastic syndrome (MDS) patients who often show abnormalities in their immunophenotype. We explored the potential impact of AZA on these immunophenotypic abnormalities in serial bone marrow studies performed in 81 patients from five centers. We compared the immunophenotypic features before and after therapy with AZA, established definitions consistent with flow cytometry immunophenotyping (FCI) improvement, and explored its clinical significance. After a median of 6 cycles of AZA, 41% of patients showed a FCI improvement and this finding associated with best possible clinical response (P < 0.001). FCI improvement also correlated with hematological improvement (HI) (53/78 patients; 68%), independently of their eligibility for stem cell transplantation. Among patients who achieved a HI after 6 cycles of AZA, the probability of maintaining this response at 12 cycles of AZA was twice as large (67%) for those patients who also achieved a FCI improvement after 6 cycles of AZA as compared to patients who did not (33%, P < 0.01). These findings support that monitoring of the immunophenotypic abnormalities during therapy with AZA may assist in redefining the quality of response in patients with MDS.

RESUMO

BACKGROUND: Prognostic factors of poor outcome in patients with hematological malignancies and COVID-19 are poorly defined. PATIENTS AND METHODS: This was a Spanish transplant group and cell therapy (GETH) multicenter retrospective observational study, which included a large cohort of blood cancer patients with laboratory-confirmed SARS-CoV-2 infection through PCR assays from March 1st 2020 to May 15th 2020. RESULTS: We included 367 pediatric and adult patients with hematological malignancies, including recipients of autologous (ASCT) (n = 58) or allogeneic stem cell transplantation (allo-SCT) (n = 65) from 41 hospitals in Spain. Median age of patients was 64 years (range 1-93.8). Recipients of ASCT and allo-SCT showed lower mortality rates (17% and 18%, respectively) compared to non-SCT patients (31%) (p = 0.02). Prognostic factors identified for day 45 overall mortality (OM) by logistic regression multivariate analysis included age > 70 years [odds ratio (OR) 2.1, 95% confidence interval (CI) 1.2-3.8, p = 0.011]; uncontrolled hematological malignancy (OR 2.9, 95% CI 1.6-5.2, p < 0.0001); ECOG 3-4 (OR, 2.56, 95% CI 1.4-4.7, p = 0.003); neutropenia (< 0.5 × 109/L) (OR 2.8, 95% CI 1.3-6.1, p = 0.01); and a C-reactive protein (CRP) > 20 mg/dL (OR 3.3, 95% CI 1.7-6.4, p < 0.0001). In multivariate analysis of 216 patients with very severe COVID-19, treatment with azithromycin or low dose corticosteroids was associated with lower OM (OR 0.42, 95% CI 0.2-0.89 and OR 0.31, 95% CI 0.11-0.87, respectively, p = 0.02) whereas the use of hidroxycloroquine did not show significant improvement in OM (OR 0.64, 95% CI 0.37-1.1, P = 0.1). CONCLUSIONS: In most patients with hematological malignancies COVID-19 mortality was directly driven by older age, disease status, performance status, as well as by immune (neutropenia) parameters and level of inflammation (high CRP). Use of azithromycin and low dose corticosteroids may be of value in very severe COVID-19.

RESUMO

Scoring systems for lower-risk myelodysplastic syndrome (LR-MDS) recognize patients with a poorer than expected outcome. This study retrospectively analyzes the role of azacitidine in LR-MDS with adverse risk score and compared to an historical cohort treated with best supportive care or erythropoiesis-stimulating agents. Overall response to AZA was 40%. One and 2-year probabilities of survival were 62% and 45% for AZA vs. 25% and 11% (P=10(-4)). In a multivariable time-dependent analysis, response to AZA (CR/PR/HI) was associated with an improved survival (HR=0.234, 95% CI, 0.063-0.0863; P=0.029). Thrombocytopenia (<50 × 10(9)L(-1)) is confirmed as an adverse parameter in LR-MDS (HR=1.649, 95% CI, 1.012-2.687; P=0.045).

RESUMO

We investigated the effectiveness and tolerability of azacitidine in patients with World Health Organization-defined myelodysplastic syndromes, or acute myeloid leukemia with 20-30% bone marrow blasts. Patients were treated with azacitidine, with one of three dosage regimens: for 5 days (AZA 5); 7 days including a 2-day break (AZA 5-2-2); or 7 days (AZA 7); all 28-day cycles. Overall response rates were 39.4%, 67.9%, and 51.3%, respectively, and median overall survival (OS) durations were 13.2, 19.1, and 14.9 months. Neutropenia was the most common grade 3-4 adverse event. These results suggest better effectiveness-tolerability profiles for 7-day schedules.

RESUMO

This study was designed to assess the efficacy and safety of an infusional DA-EPOCH (dose-adjusted etoposide/vincristine/doxorubicin/bolus cyclophosphamide/prednisone) and rituximab (DA-EPOCH-R) regimen for patients with poor prognosis diffuse large B-cell lymphoma (DLBCL). Thirty-three patients, aged 21-76 years, with an age-adjusted International Prognostic Index (IPI) of 2 or 3, were enrolled, and 31/33 patients were evaluable for response. Consolidative radiation therapy was given to eight patients with bulky (> or =10 cm) disease at presentation. Overall, 26 patients (83.8%) achieved a complete remission (CR), four patients (12.9%) achieved a partial remission, and one patient (3.2%) died during induction. Two patients relapsed (7.6%) within 15 months. Grade 3-4 neutropenia developed in 52% of cycles and neutropenic fever in 14% of cycles (51% of patients). The estimates for event-free survival (EFS) and overall survival at 2 years were 68% and 75% respectively. The only factor related to poor EFS was the presence of three age-adjusted IPI-risk factors. We conclude that DA-EPOCH-R has clinically significant activity with a favourable toxicity profile for poor-prognostic DLBCL patients. The administration of DA-EPOCH-R as an outpatient regimen by using a single portable infusion pump may be a feasible alternative to improve the compliance and to reduce the total cost of this very effective regimen.

RESUMO

The aims of this study were to evaluate the clinical characteristics of HIV-negative patients affected by lymphoproliferative disorders (LPD) who developed progressive multifocal leukoencephalopathy (PML), to delineate the risk factors, and to analyze whether the new antineoplastic therapies are changing the natural history of this infectious disease. We retrospectively analyzed 46 cases with confirmed LPD-associated PML published from 1958 to 2004. Patients were stratified according to two different time periods: group A included patients diagnosed before 1989, and group B included patients diagnosed since 1990, after introduction of purine analogues. Group A patients (n = 22) had received alkylating agents and/or radiotherapy, and the majority (63.6%) had advanced Hodgkin disease. At univariate analysis, uncontrolled Hodgkin disease was the only risk factor for PML. In group B patients (n = 24), the most frequent treatments received were purine analogues (58.3%) and high-dose therapy with hematopoietic stem cell transplantation (33.3%; HDT/HSCT). B-cell chronic lymphocytic leukemia (45.8%) and aggressive non-Hodgkin lymphoma (24.9%) were the most frequent underlying LPDs. Patients treated with purine analogues were more likely to have active LPD, lower CD4 cell counts, and to be older and male than were HSCT recipients. The median interval from purine analogues or HDT/HSCT to PML was 11 months. In HDT/HSCT recipients, this interval was delayed for 10 months when peri-transplantation rituximab was used. Univariate analysis identified age >55 years, male sex, and CD4 cell counts

RESUMO

Trichoderma species have been recognized to be pathogenic in immunosuppressed hosts with increasing frequency. Trichoderma species are responsible for continuous ambulatory peritoneal dialysis associated peritonitis and infections in immunocompromised patients with a hematologic malignancy or solid organ transplantation. Trichoderma longibrachiatum is the most common species involved in these infections. We report the first case of nonfatal pulmonary infection caused by Trichoderma viride in leukemia patient. It had a successful answer to new antifungal agents as voriconazole and caspofungin. Trichoderma viride was isolated from pulmonary aspirate culture from a 54-year-old female who had received chemotherapy for acute myeloid leukemia. The minimal inhibitory concentrations for the organism were the following: amphotericin B (0.25 microg/mL) and voriconazole (2 microg/mL). Initially, she was treated unsuccessful with liposomal amphotericin B and voriconazole and caspofungin were added later. The patient is alive. We report one case along review of the literature.

RESUMO

We measured platelet function by standard aggregometric tests and by the PFA-100 (Dade Behring, Newark, DE) in samples from 55 patients with primary thrombocythemia (PT) and 26 healthy volunteers. Platelet function was evaluated in platelet-rich plasma by aggregation tests. PFA-100 studies (closure time) were performed in citrated whole blood using collagen-adenosine diphosphate (ADP) and collagen-epinephrine cartridges. Plasma levels of von Willebrand factor (vWF) also were measured. The mean +/- SD closure time for patients vs volunteers for the collagen-epinephrine cartridge was prolonged (210.8 +/- 62.2 vs 118.1 +/- 19.6 seconds; P < .001); results were abnormal for 38 patients (69%). Results with the collagen-ADP cartridge also were abnormal in patients (134.3 +/- 58.4 seconds) vs volunteers (87.3 +/- 15.6 seconds; P < .001); closure time was prolonged in 23 patients (42%). A decreased response to epinephrine (38.4% +/- 34.2% vs 82.5% +/- 10.3%; P < .001), the main defect detected by platelet aggregation tests, affected 32 patients (58%). Platelet response to collagen also was abnormal (52.0% +/- 34.6% vs 86.0% +/- 10.1%; P < .01) but affected only 21 patients (38%). vWF levels for patients were normal. The results seem to confirm that platelet function in patients with PT is abnormal and show that platelet function can be assessed by an easy, reproducible, and sensitive method, the PFA-100. Closure time usually was prolonged; this feature could be applied in the diagnosis of PT.

RESUMO

We evaluated a new portable monitor (AvoSure PT PRO, Menarini Diagnostics, Firenze, Italy) developed to test the prothrombin time in capillary blood and plasma by comparing it with the standard laboratory determination. We studied 62 patients receiving acenocoumarol therapy. The international normalized ratio (INR) in capillary blood was analyzed by 2 methods: AvoSure PT PRO and Thrombotrack Nycomed Analyzer (Axis-Shield, Dundee, Scotland). Parallel studies were performed in plasma samples by a reference method using the Behring Coagulation Timer (Behring Diagnostics, Marburg, Germany). Plasma samples also were tested with the AvoSure PT PRO. Correlation was good for INR values for capillary blood and plasma samples by AvoSure PT PRO and our reference method (R2 = 0.8596) and for capillary blood samples tested by the AvoSure PT PRO and Thrombotrack Nycomed Analyzer (R2 = 0.8875). The correlation for INR in capillary blood and plasma samples by AvoSure PT PRO was 0.6939 (P < .0004). Capillary blood determinations are rapid and effective for monitoring oral anticoagulation therapy and have a high correlation to plasma determinations. AvoSure PT PRO is accurate for controlling INR in plasma and capillary blood samples, may be used in outpatient clinics, and has advantages over previous portable monitors.

RESUMO

We prospectively evaluated 131 consecutive episodes of fever and chemotherapy-induced neutropenia in 85 adults with haematological malignancies to determine whether older patients (aged < 60 years) have different causes of fever and outcome than younger adults (aged < 60 years). Patients were stratified into high-risk and low-risk groups according to previously published criteria. High-risk patients received ceftazidime plus amikacin and low-risk patients received ceftazidime alone. All patients were hospitalized until fever and neutropenia resolved. Ninety one high-risk episodes were documented: 56 occurring in older patients (mean age 69 years) and 35 in younger adults (mean age 45 years). Non-Hodkgin's lymphoma and acute myeloid leukaemia were the most frequent underlying neoplasias in both age groups. Intensity of chemotherapy was similar in both age groups. Mean neutrophil count at entry, median duration of neutropenia, rate of documented infection, incidence of bacteraemia, response to therapy, overall mortality and infectious mortality were similar in the two high-risk age subgroups. The elderly subgroup had a trend to have more Gram-negative infections and the younger patients more Gram-positive infections. In addition, 40 low-risk episodes were registered: 29 in elderly patients (mean age 68 years) and 11 in younger patients (mean age 44 years). Elderly low-risk patients had more concurrent diseases that younger ones (P = 0.124). Mean neutrophil count at entry, median duration of severe neutropenia and rate of response were similar in the two age subgroups. All low-risk patients survived. In conclusion, elderly haematological cancer patients with febrile neutropenia show similar rates of infection and outcome to younger ones.

RESUMO

We report a case of spontaneous gas gangrene (SGG), the most rapidly progressive form of clostridial infection, in a patient with non-Hodgkin's lymphoma (NHL). We review the literature and examine the association between these two entities. A 43-year-old man with NHL developed fatal C. perfringens-associated SGG and massive hemolysis during induction chemotherapy. Although patients with NHL usually have several risk factors of SGG, such as bowel involvement or neutropenia, only two cases have been described previously in detail. Common features of all reports are a delayed diagnosis and a fatal outcome. Awareness of this condition should result in prompt antibiotic therapy at the onset of typical presenting symptoms in any lymphoma patient, especially if risk factors are present.
