PURPOSE The strong dose-dependent association between anthracyclines and cardiomyopathy is further exacerbated by the co-occurrence of cardiovascular risk factors (diabetes and hypertension). The high morbidity associated with cardiomyopathy necessitates an understanding of the underlying pathogenesis so that targeted interventions can be developed. PATIENTS AND METHODS By using a two-stage d...
Anthracyclines (i.e., doxorubicin, daunorubicin) have significant impact on outcome in many pediatric chemotherapy protocols and therefore remain the mainstay of treatment. The objective of this study was to identify the risk factors for anthracycline induced cardiac dysfunction in pediatric patients. Multiple logistic regression model was applied to assess the risk factors for development of c...
First-step Adriamycin (doxorubicin)-resistant mutants of the murine erythroleukemia cell line PC4 were cloned from Adriamycin-containing (10 ng/ml) methylcellulose at a frequency of 3 x 10~4.They demonstrated 1.6to 2.4-fold stable resistance to Adriamycin. Most were cross-resistant to etoposide, but not to vincristine, and were without enhanced expression of mdr genes, which code for P-glycopro...
Biomarkers predicting resistance to particular chemotherapy regimens could play a key role in optimally individualized treatment concepts. PTK7 (protein tyrosine kinase 7) belongs to the receptor tyrosine kinase family involved in several physiological, but also malignant, cell behaviors. Recent studies in acute myeloid leukemia have associated PTK7 expression with resistance to anthracycline t...
BACKGROUND The HER2 gene, which encodes the growth factor receptor HER2, is amplified and HER2 is overexpressed in 25 to 30 percent of breast cancers, increasing the aggressiveness of the tumor. METHODS We evaluated the efficacy and safety of trastuzumab, a recombinant monoclonal antibody against HER2, in women with metastatic breast cancer that overexpressed HER2. We randomly assigned 234 pa...

BACKGROUND Extensive studies have confirmed the efficacy of taxanes in combination with anthracycline-based chemotherapy on breast cancer. However, few studies have assessed the efficacy of weekly taxane-anthracycline regimens on locally advanced breast cancer. This study was to compare the efficacy and safety of a weekly taxane-anthracycline regimen with those of tri-weekly anthracycline-based...
Purpose: DNA methyltransferase 3A (DNMT3A) is one of the commonly mutated genes in acute myelogenous leukemia (AML). Reports on the prognostic significance ofDNMT3Amutations have been inconsistent, and most of the data are available only for patients 60 years of age or younger.We hypothesized that this inconsistency is due to an interaction between the dose of anthracycline used in induction th...
T hirty years ago, the introduction of anthracyclines, such as doxorubicin and epirubicin, gave oncologists a more effective cytotoxic agent and commenced the drugs ' long reign as the foundation of early breast cancer therapy. But some experts now argue that with the advent of newer drugs — trastuzumab (Herceptin) and the taxanes, such as pacli-taxel (Taxol) and docetaxel (Taxotere) — there is...
