Consistency matters: measurement invariance of the EORTC QLQ-C30 questionnaire in patients with hematologic malignancies

ConclusionsOur findings support measurement invariance of the EORTC QLQ-C30 in a large sample of patients with hematological malignancies. The results showed that the number of non-invariant items was negligible, suggesting that this questionnaire is a valid and robust measurement tool in patients with hematological malignancies, also for comparisons across groups and time.

In this study, all 135 patients received CM treatment for at least 36 months. The response rates for CM treatment were 81.53% (106/130) for hematological improvement in 130 MDS-RCMD patients and 80% (4/5) for bone marrow CR in 5 MDS-RAEB patients, respectively. The Human Methylation 850K BeadChip showed that 115 genes (50.88%) were aberrantly hypomethylated in 5 MDS patients compared with 3 healthy individuals. GO-analysis showed that these hypomethylated genes participated in many cancer-related biological functions and pathways. Furthermore, 60 genes were hypermethylated and the protein expression level of DNMT1 was sign...

CONCLUSION: This study showed the frequency and pattern of chromosomal abnormalities of MDS patients in upper northern Thailand were different from other populations. MDS with isolated chromosome 5 abnormalities had clinical characteristics corresponding with patients in good prognosis risk group. However, MDS patients with chromosome 7 and complex abnormalities showed higher percentage blast of BM which high risk to progression to acute myeloid leukemia (AML). Combined CC and FISH techniques detect chromosomal abnormalities with greater frequency than when either technique is used alone.. PMID: 32212788 [PubMed - in process]

TheASXL1 mutation frequency is high in AML ‐MRC patients being its presence associated with specific characteristics, including morphological signs of dysplasia. This association raises the possible role ofASXL1 as a surrogate marker in AML ‐MRC, which could facilitate the diagnosis of patients within this group when the karyotype is normal, and especially when the assessment of multilineage dysplasia morphologically is difficult. This mutation could be used as a worst outcome marker in de novo AML‐MRC with intermediate‐risk kar yotype. AbstractAcute myeloid leukemia with myelodysplasia ‐related changes (AML...

Cells become senescent in response to a variety of circumstances. The vast majority are cases of replicative senescence, somatic cells reaching the Hayflick limit. Cell damage and toxic environments also produce senescence, and senescent cells are also created as a part of the wound healing process. A senescent cell ceases replication and begins to secrete inflammatory and pro-growth signals, altering the nearby extracellular matrix and behavior of surrounding cells - even encouraging them to become senescent as well. Near all senescent cells last a short time only, as they self-destruct or are removed by the immune...

We present the case of a 67-year-old man with prostate cancer who had no findings of recurrence, except diffuse radiotracer uptake in the bone marrow in 68Ga-PSMA PET/CT. Bone marrow uptake was also represented as multiple focal increased spots without any corresponding lytic or sclerotic lesions in CT. MRI revealed a high and homogeneous T2 signal within the bone marrow, without any contrast-enhanced or diffusion-restricted lesions. Further workup, including a bone marrow biopsy, revealed the diagnosis of myelodysplastic syndrome.

s Bernard Deregulation of pre-mRNA splicing is observed in many cancers and hematological malignancies. Genes encoding splicing factors are frequently mutated in myelodysplastic syndromes, in which SF3B1 mutations are the most frequent. SF3B1 is an essential component of the U2 small nuclear ribonucleoprotein particle that interacts with branch point sequences close to the 3’ splice site during pre-mRNA splicing. SF3B1 mutations mostly lead to substitutions at restricted sites in the highly conserved HEAT domain, causing a modification of its function. We found that SF3B1 was aberrantly spliced in various ...

Authors: Gorshein E, Weber UM, Gore S Abstract Introduction: Myelodysplastic Syndrome (MDS) represents a group of cancers characterized by abnormal blood cell formation and maturation, leading to various degrees of cytopenias and potential transformation to acute myeloid leukemia. Deletion of the long arm of chromosome 5 (del(5q)) is the most common clonal chromosomal anomaly in MDS, yet the population in this disease subtype is quite heterogeneous. This manuscript analyzes literature on high-risk MDS with del(5q) abnormalities.Areas covered: The paper will review outcomes with lenalidomide among high-risk MDS pati...

Purpose of review This review outlines the advancements that have been made in computational analysis for clinical flow cytometry data in hematological malignancies. Recent findings In recent years, computational analysis methods have been applied to clinical flow cytometry data of hematological malignancies with promising results. Most studies combined dimension reduction (principle component analysis) or clustering methods (FlowSOM, generalized mixture models) with machine learning classifiers (support vector machines, random forest). For diagnosis and classification of hematological malignancies, many studies have ...
