The Relevance of Mass Spectrometry Analysis for Personalized Medicine through Its Successful Application in Cancer "Omics".

Mass spectrometry (MS) is an essential analytical technology on which the emerging omics domains; such as genomics; transcriptomics; proteomics and metabolomics; are based. This quantifiable technique allows for the identification of thousands of proteins from cell culture; bodily fluids or tissue using either global or targeted strategies; or detection of biologically active metabolites in ultra amounts. The routine performance of MS technology in the oncological field provides a better understanding of human diseases in terms of pathophysiology; prevention; diagnosis and treatment; as well a

Activated Ras as a Therapeutic Target: Constraints on Directly Targeting Ras Isoforms and Wild-Type versus Mutated Proteins.

The ability to selectively and directly target activated Ras would provide immense utility for treatment of the numerous cancers that are driven by oncogenic Ras mutations. Patients with disorders driven by overactivated wild-type Ras proteins, such as type 1 neurofibromatosis, might also benefit from progress made in that context. Activated Ras is an extremely challenging direct drug target due to the inherent difficulties in disrupting the protein:protein interactions that underlie its activation and function. Major investments have been made to target Ras through indirect routes. Inhibition

Dynamic multimodal survival prediction in multiple myeloma integrating gene expression, longitudinal laboratory measurements, and treatment history.

Prognostic stratification in multiple myeloma (MM) relies on staging systems fixed at diagnosis, discarding temporal information accumulated during treatment. We developed a dynamic multimodal framework that predicts residual overall survival from observation windows of 1-18 months post-diagnosis. The model integrates DeepInsight-transformed gene expression, longitudinal trajectories of 10 laboratory analytes, and treatment history through missingness-aware gated fusion. On the Multiple Myeloma Research Foundation (MMRF) cohort from the Relating Clinical Outcomes in Multiple Myeloma to Persona

Polymorphisms in the promoter region of the CRBN gene as a predictive factor for the first-line CTD therapy in multiple myeloma patients.

Cereblon is a primary molecular target for immunomodulatory drugs. The aim of this study was to evaluate the influence of selected clinical and molecular factors including single nucleotide polymorphisms (SNPs) in CRBN gene on the efficacy of first line CTD (cyclophosphamide, thalidomide, dexamethasone) chemotherapy in patients with multiple myeloma.

CXCR4 induces memory formation over exhaustion in CAR-T cells to achieve durable leukemia targeting.

Chimeric antigen receptor (CAR)-T cell therapy has transformed the treatment of B-cell malignancies, but its success in acute myeloid leukemia (AML) remains limited. Durable responses depend on the formation of long-lived memory T cells, whereas T cell exhaustion contributes to non-response and relapse. In patients with AML who achieved remission after cord blood transplantation, we here first observe enrichment of memory T cells with high expression of the chemokine receptor CXCR4. Next, we show that engineering CAR-T cells to co-express CXCR4 enhances their persistence and anti-leukemic acti

Infections, autoimmunity and immunodeficiencies are the leading etiologies of non-cystic fibrosis bronchiectasis in adults from the southwest of Colombia.

INTRODUCTION: Non-cystic fibrosis bronchiectasis is a complex medical condition with multiple etiologies, characterized by chronic productive cough and radiologic evidence of airway lumen dilation and wall thickening. Associated exacerbations and declining lung function contribute to increasing disability and mortality. There are no data about the prevalence of non-cystic fibrosis bronchiectasis etiologies in the Colombian population. OBJECTIVE: To investigate non-cystic fibrosis bronchiectasis etiology and clinical characteristics in adults evaluated in the southwest of Colombia. MATERIALS

Prior cancer history and suitability for kidney transplantation.

Kidney transplantation is the optimal treatment for most patients with kidney failure. For patients with a prior history of treated cancers, listing and transplant eligibility decisions are complex. Patients and health professionals are obliged to consider the time-periods between cancer cure and transplantation, the risk of cancer recurrence under the influence of immunosuppression and anti-cancer treatment options if the disease recurs. Cancer recurrence is associated with a high mortality rate, thus potentially reduces the projected survival benefit of transplantation, and dampens the utili

Cancer Patients' Experiences with Telehealth before and during the COVID-19 Pandemic in British Columbia.

BackgroundPatients have had their cancer care either postponed or changed to telehealth visits to reduce exposure to COVID-19. However, it is unclear how these changes may have affected their experiences. We aim to identify patient characteristics that affect telehealth experiences and evaluate their preferences for using telehealth in the future.MethodsPatients who completed the Outpatient Cancer Care (OCC) Patient Experience Survey were invited to participate. They comepleted the modified OCC Survey, which focused on telehealth during the pandemic. Linear and logistic regression analyses wer

Translational progress on tumor biomarkers.

There is an urgent need to apply basic research achievements to the clinic. In particular, mechanistic studies should be developed by bench researchers, depending upon clinical demands, in order to improve the survival and quality of life of cancer patients. To date, translational medicine has been addressed in cancer biology, particularly in the identification and characterization of novel tumor biomarkers. This review focuses on the recent achievements and clinical application prospects in tumor biomarkers based on translational medicine.

A thirteen-gene expression signature predicts survival of patients with pancreatic cancer and identifies new genes of interest.

BackgroundCurrently, prognostication for pancreatic ductal adenocarcinoma (PDAC) is based upon a coarse clinical staging system. Thus, more accurate prognostic tests are needed for PDAC patients to aid treatment decisions.Methods and findingsAffymetrix gene expression profiling was carried out on 15 human PDAC tumors and from the data we identified a 13-gene expression signature (risk score) that correlated with patient survival. The gene expression risk score was then independently validated using published gene expression data and survival data for an additional 101 patients with pancreatic

Emerging role of low-frequency somatic mutations in cancer relapse: from early detection to precision oncology.

Somatic mutations with low variant allele frequencies offer a highly sensitive lens for detecting cancer relapse driven by diverse causes, including clonal evolution and therapy resistance. Advances in next-generation sequencing have enabled robust subclonal variant identification that typically fall below conventional detection limits, supporting a comprehensive understanding of individual molecular profiles that can lead to relapse. These low-level alterations frequently emerge before clinical or radiological relapse and can inform response-adaptive treatment decisions. This review integrate

Serum neurofilament light chain (sNFL) as a predictive biomarker for Chemotherapy-induced peripheral neurotoxicity (CIPN): consideration of current evidence, validation steps, and barriers to CIPN biomarker implementation in clinical practice-a narrative review.

PurposeSeveral anticancer drugs can cause chemotherapy-induced peripheral neurotoxicity (CIPN) in approximately 70% of patients; of these, 30% continue to have chronic symptoms hampering quality of life. As more people live with and beyond cancer therapy, it is becoming increasingly important for clinicians to assess those at higher risk of CIPN and provide care for managing CIPN severity. Biomarkers could be appropriate in this regard. However, an initial step towards biomarker-informed care is to advance scientific knowledge regarding the potential of current biomarkers such as neurofilament

Elevated D-dimer levels in high-risk multiple myeloma patients: a systematic review and meta-analysis.

BACKGROUND: Patients with multiple myeloma (MM) exhibit elevated thrombotic risk and variable disease outcomes. D-dimer, a fibrin degradation product, may serve as a biomarker reflecting both hypercoagulability and disease severity. This systematic review and meta-analysis compared D-dimer levels between MM patient subgroups defined by either poor prognostic features (e.g., advanced ISS stage) or thrombotic events and reference groups, with detailed discussion of how D-dimer integration reshapes routine thromboprophylaxis strategies and upgrades classic prognostic staging tools (ISS, R-ISS, IM

Нейродегенеративные биомаркеры при множественном склерозе: на стыке между исследованиями и клинической практикой.

Множественный склероз (MS) — хроническое аутоиммунное расстройство, характеризующееся воспалением, обезвоживанием и нейродегенерацией в центральной нервной системе (CNS). Хотя подстрекательские компоненты MS были тщательно изучены, прогрессивный нейродегенеративный аспект по-прежнему является одним из важнейших факторов, способствующих долгосрочной инвалидности. Поэтому выявление и проверка биомаркеров, связанных с нейродегенеративными процессами, имеют важнейшее значение для улучшения диагностики, прогнозирования и мониторинга лечения. В рамках этого обзора изучаются цереброспинные жидкости (

MSC Senescence-Related Genes Are Associated with Myeloma Prognosis and Lipid Metabolism-Mediated Resistance to Proteasome Inhibitors.

BackgroundComplex carcinogenic mechanisms and the existence of tumour heterogeneity in multiple myeloma (MM) prevent the most commonly used staging system from effectively interpreting the prognosis of patients. Since the microenvironment plays an important role in driving tumour development and MM occurs most often in middle-aged and elderly patients, we hypothesize that ageing of bone marrow mesenchymal stem cells (BM-MSCs) may be associated with the progression of MM.MethodsIn this study, we collected the transcriptome data on MM from The Cancer Genome Atlas (TCGA) and the Gene Expression O
