Quality of life assessment in multiple myeloma patients undergoing dose-reduced tandem autologous stem cell transplantation.

Few studies exist that consider health-related quality of life (HR-QoL) in patients with multiple myeloma (MM) undergoing tandem autologous stem cell transplantation (TASCT). Eighteen patients with advanced MM who underwent dose-modified TASCT were enrolled in this study between March 2006 and March 2008. Patients <60 year old (10) received conditioning with melphalan 140 mg/m(2) and patients who were ≥60 years (8) received 100 mg/m(2). The median age was 57.5 years (range 35-69). We conducted the European Organization of Research and Treatment of Cancer (EORTC) QLQ-C30 and the QLQ-MY24 questi

Objective: The aim of this study was to investigate changes in P3 amplitude and latency to emotional stimuli with different arousal and valence levels after a mindfulness-based intervention in oncological patients. Methods: P3 amplitude and latency at Fz, Cz, and Pz to emotional salient stimuli differing in valence (positive vs. negative) and arousal (low vs. high) levels were measured in 17 oncological patients (Mage = 51 years, SD = 9.17, females = 11) before and after a mindfulness-based intervention in a waitlist-controlled clinical trial. Group sessions were held 2x/week over a period of

Education, Employment, and Financial Outcomes in Adolescent and Young Adult Cancer Survivors-A Systematic Review.

Adolescents and young adults (AYAs) with cancer face unique challenges. We aimed to describe (i) education, employment, and financial outcomes and (ii) determinants for adverse outcomes in AYA cancer survivors. We performed a systematic literature search. We included original research articles on AYA (15-39 years of age) cancer survivors (≥2 years after diagnosis) and our outcomes of interest. We narratively synthesized the results of the included articles. We included 35 articles (24 quantitative and 11 qualitative studies).

COVID-19 burden of illness in people who are immunocompromised due to cancer: an expert opinion review.

From the beginning of the pandemic, people with cancer have experienced a high burden from COVID-19 compared with the general population, both in terms of severe COVID-19-related outcomes and reduced health-related quality of life and mental health. This review presents and discusses expert views on the burden of COVID-19 in individuals with cancer throughout the pandemic. The literature suggests that early in the pandemic, people with cancer had a disproportionately high risk of COVID-19-related hospitalization compared with the general population. This trend continued throughout the pandemic

CXCL12/CXCR4 axis supports mitochondrial trafficking in tumor myeloma microenvironment.

Mesenchymal stromal cells (MSCs) within the protective microenvironment of multiple myeloma (MM) promote tumor growth, confer chemoresistance and support metabolic needs of plasma cells (PCs) even transferring mitochondria. In this scenario, heterocellular communication and dysregulation of critical signaling axes are among the major contributors to progression and treatment failure. Here, we report that myeloma MSCs have decreased reliance on mitochondrial metabolism as compared to healthy MSCs and increased tendency to deliver mitochondria to MM cells, suggesting that this intercellular exch

Evidence of brain-derived neurotrophic factor in ameliorating cancer-related cognitive impairment: A systematic review of human studies.

Brain-derived neurotrophic factor (BDNF) plays an essential role in neurogenesis and neuroplasticity and may be a key protein in cancer-related cognitive impairment (CRCI). This systematic review assessed the relationship between BDNF biomarkers and neurocognitive outcomes in cancer patients and survivors. A search in PubMed, Scopus, and PsycINFO yielded 638 articles, of which 26 were eligible. Fourteen (54 %) studied BDNF protein levels while 15 (58 %) analyzed BDNF rs6265 polymorphism. Of the nine observational studies reporting BDNF plasma/serum levels, five (56 %) exhibited a positive asso

Early Palliative Care in Acute Myeloid Leukemia.

BackgroundSeveral novel targeted therapies seem to improve the outcome of acute myeloid leukemia (AML) patients. Nonetheless, the 5-year survival rate remains below 40%, and the trajectory of the disease remains physically and emotionally challenging, with little time to make relevant decisions. For patients with advanced solid tumors, the integration of early palliative care (EPC) with standard oncologic care a few weeks after diagnosis has demonstrated several benefits. However, this model is underutilized in patients with hematologic malignancies.MethodsIn this article, we analyze the palli

Quality of life of survivors 1 year after the diagnosis of diffuse large B-cell lymphoma: a LYSA study.

Health-related quality of life (HRQoL) is a multidimensional concept including physical, emotional, social, and cognitive functions, disease symptoms, and side effects of treatment. Differences in HRQoL due to gender, existence of comorbidities, and number of chemotherapy cycles are little explored in diffuse large B-cell lymphoma (DLBCL) survivors. Our objective was to investigate whether differences in HRQoL in function of these factors exist 1 year after the diagnosis of DLBCL. One hundred and one patients, enrolled in the RT3 (Real-Time Tailored Therapy) Study, answered self-administrated
