RESUMEN

The introduction of chimeric antigen receptor T-cell (CAR-T cell) therapy has changed the treatment landscape of diffuse large B-cell lymphoma (DLBCL). However, the optimal treatment strategy after relapse after this therapy still needs to be elucidated. In this report, we describe the case of a 67-year-old male who relapsed after treatment with tisagenlecleucel as a third-line therapy. We present our approach to treatment after relapse, in which we tried to sustain the circulating chimeric antigen receptor T-cells. This is reflected by the kinetics of the chimeric antigen receptor T-cells during these treatments.

RESUMEN

Transfusion dependency and iron overload are common among patients with myelodysplastic syndromes (MDS) treated with red blood cell (RBC) transfusions. Transfusion dependency is associated with leukemic progression and shorter survival. Guidelines recommend iron chelation therapy to manage iron overload, however little is known about the chelation patterns in daily clinical practice. The objective of this multicenter, retrospective, cross-sectional, observational study was to evaluate iron status and its management in transfusion-dependent MDS patients. A total of 193 patient records from 29 centers were eligible for inclusion. Median patient age was 76, and median age at diagnosis of MDS was 74. Patients had received an average of 13.4 ± 7.6 RBC units in the past 4 months; 44% had received more than 50 units since their MDS diagnosis. Medium serum ferritin was 1,550 µg/L. Ninety patients (46.6%) received iron chelation therapy with either deferoxamine (41%), deferasirox (36%), and deferoxamine followed by deferasirox (23%). There were no statistically significant differences between chelated and nonchelated patients in terms of International Prognostic Scoring System (IPSS), French-American-British (FAB), and/or World Health Organization (WHO) status, though chelated patients had received more RBC transfusions (p = 0.014). Iron chelation therapy may be underutilized in transfusion-dependent patients. Undertreatment can be reduced by complementing sound clinical judgment with the generally accepted guidelines of a serum ferritin level >1,000 µg/L and/or two or more RBC transfusions per month for the past year; considering patients on the basis of their IPSS, FAB, and/or WHO status; and individually tailored treatment regimens. Prospective randomized trials are necessary to establish causally the efficacy of iron chelation therapy in MDS.

RESUMEN

Multiple myeloma is a plasma cell (PC) malignancy characterized by the accumulation of monoclonal PCs in the bone marrow and the production of large amounts of a monoclonal immunoglobulin or paraprotein. In the past years, new approaches in the diagnosis and treatment were introduced aiming to identify high-risk patients who need proper anti-myeloma treatment. Intensive therapy including autologous hematopoietic stem cell transplantation and the new agents bortezomib, thalidomide, and lenalidomide have improved patients' responses. Further optimalization of the different treatment schedules in well-defined patient groups may prolong their survival. Patient stratification is currently based on patient characteristics, extent of myeloma disease, and associated cytogenetic and laboratory anomalies. More and more gene expression studies are introduced to stratify patients and to individualize therapy.

RESUMEN

BACKGROUND: Most patients with myelodysplastic syndromes (MDS) require transfusions at the risk of iron overload and associated organ damage, and death. Emerging evidence indicates that iron chelation therapy (ICT) could reduce mortality and improve survival in transfusion-dependent MDS patients, especially those classified as International Prognostic Scoring System (IPSS) Low or Intermediate-1 (Low/Int-1). METHODS: Follow-up of a retrospective study. Sample included 127 Low/Int-1 MDS patients from 28 centers in Belgium. Statistical analysis stratified by duration (≥6 versus <6 months) and quality of chelation (adequate versus weak). RESULTS: Crude chelation rate was 63% but 88% among patients with serum ferritin ≥1000 µg/L. Of the 80 chelated patients, 70% were chelated adequately mainly with deferasirox (26%) or deferasirox following deferoxamine (39%). Mortality was 70% among non-chelated, 40% among chelated, 32% among patients chelated ≥6 m, and 30% among patients chelated adequately; with a trend toward reduced cardiac mortality in chelated patients. Overall, median overall survival (OS) was 10.2 years for chelated and 3.1 years for non-chelated patients (p<0.001). For patients chelated ≥6 m or patients classified as adequately chelated, median OS was 10.5 years. Mortality increased as a function of average monthly transfusion intensity (HR=1.08, p=0.04) but was lower in patients receiving adequate chelation or chelation ≥6 m (HR=0.24, p<0.001). CONCLUSION: Six or more months of adequate ICT is associated with markedly better overall survival. This suggests a possible survival benefit of ICT in transfusion-dependent patients with lower-risk MDS.

RESUMEN

The World Health Organization introduced flow cytometry as an additional criterion for diagnosis of myelodysplastic syndromes (MDS). Aberrant antigen expression on bone marrow (BM) blasts may identify "low-grade MDS." This study aimed to examine differences in antigen expression on CD34+ BM cells between patients with MDS and those with secondary cytopenia. BM aspirates of 175 patients with cytopenia were classified as MDS or secondary cytopenia. Expression of stem cell antigens (CD34, CD133), myeloid antigens (CD13, CD33), B-cell antigens (CD19, CD10), growth factor receptors (CD117, CD123), and chemokine receptor (CD184) was examined. Thirty-two normal adults and 49 patients with CD34+ acute myeloid leukemia (AML) were also examined. High percentage of CD34+ cells, CD117 and CD123 overexpression, and abnormal CD45 expression on these cells are the best markers for MDS. These phenotypic aberrancies correlate with number of blasts and degree of dysplasia, and were similar to those in CD34+ AML, thus reflecting the relationship between these disorders.

RESUMEN

PURPOSE/OBJECTIVES: To evaluate the effects of a rehabilitation program on quality of life, fatigue, fear of movement (kinesiophobia), distress, anxiety, depression, and physical condition. DESIGN: Pretest/post-test. SETTING: An outpatient rehabilitation setting in the Oncology Centre at the University Hospital Brussels in Belgium. SAMPLE: 36 patients who had completed cancer treatment with a curative potential. METHODS: Participants completed a questionnaire and underwent a physical test at baseline and at the end of the program. The measurement instruments used included the European Organisation for Research and Treatment of Cancer Quality-of-Life Questionnaire-Core 30, Functional Assessment of Cancer Therapy-Fatigue, Hospital Anxiety and Depression Scale, RAND-36, Tampa Scale for Kinesiophobia, Distress Barometer, and Tecumseh Step Test. MAIN RESEARCH VARIABLES: Quality of life, fatigue, kinesiophobia, distress, anxiety, depression, and physical condition. FINDINGS: Significant improvement was observed in quality of life (p < 0.001), physical condition (p = 0.007), fatigue (p = 0.01), and depression (p = 0.012). In contrast, kinesiophobia (p = 0.229), distress (p = 0.344), and anxiety (p = 0.101) did not change significantly. CONCLUSIONS: A general and significant improvement in all aspects affecting quality of life and rehabilitation was observed, but less so for aspects that might be influenced by prognostic concerns. The relative contribution of the program versus spontaneous recovery and long-term impact need to be determined further in a prospective randomized study. IMPLICATIONS FOR NURSING: Multidisciplinary rehabilitation should become part of the total care plan for patients with cancer.
