Background: Minimal residual disease (MRD) is one of the most valuable independent prognostic factors in acute lymphoblastic leukemia (ALL). Bone marrow (BM) aspiration, however, is an invasive process. Previous studies have shown that microRNAs (miR) and extracellular vesicle (EV)-related miRs show different expression profiles at the presence of malignant cells compared to healthy controls.

Background: Refractory central nervous system (CNS) involvement is among the major causes of therapy failure in childhood acute leukemia. Applying contemporary diagnostic methods, CNS disease is often underdiagnosed. To explore more sensitive and less invasive CNS status indicators, we examined microRNA (miR) expressions and extracellular vesicle (EV) characteristics.

Background: Treatment stratification based on bone marrow minimal residual disease (MRD) at set time points has resulted in considerably improved survival in pediatric acute lymphoblastic leukemia (ALL). Treatment response is assessed using bone marrow samples. MicroRNAs (miRs) easily traffic among fluid spaces and are more stable than most other RNA classes.

Background: The treatment of acute lymphoblastic leukemia (ALL) and osteosarcoma (OSC) is very effective: the vast majority of patients recover and survive for decades. However, they still need to face serious adverse effects of chemotherapy. One of these is cardiotoxicity which may lead to progressive heart failure in the long term.

Owing to clinical trials and improvement over the past few decades, the majority of children with acute lymphoblastic leukemia (ALL) survive by first-line chemotherapy and combat with the problems of returning to community. However, many patients may have severe acute or late therapeutic side effects, and the survival rate in some groups (e.g.

Extracellular vesicles are produced in all organisms. The most intensively investigated categories of extracellular vesicles include apoptotic bodies, microvesicles and exosomes. Among a very wide range of areas, their role has been confirmed in intercellular communication, immune response and angiogenesis (in both physiological and pathological conditions).

Synopsis of recent research by authors named "Andrea Rzepiel"

  • - Andrea Rzepiel's research focuses on the utilization of microRNAs and extracellular vesicles as non-invasive biomarkers for monitoring and diagnosing childhood acute lymphoblastic leukemia (ALL) and its complications, highlighting their potential in clinical applications.
  • - Recent studies by Rzepiel demonstrate the efficacy of circulating microRNAs as indicators of minimal residual disease (MRD) and central nervous system (CNS) involvement, which are crucial in improving treatment outcomes and patient stratification.
  • - Her work also explores the genetic factors contributing to chemotherapy-related cardiotoxicity in pediatric cancer patients, emphasizing the importance of understanding adverse effects alongside treatment efficacy to enhance long-term patient survival and quality of life.
