Final 10-year results of the Breast International Group 2-98 phase III trial and the role of Ki67 in predicting benefit of adjuvant docetaxel in pati…
2015
Aim: Breast International Group (BIG) 2-98 is a randomised phase III trial that tested the effect of adding docetaxel, either in sequence to or in combination with anthracycline-based adjuvant chemotherapy, in women with node-positive breast cancer (BC). Here, we present the 10-year final trial safety and efficacy analyses. We also report an exploratory analysis on the predictive value of Ki67 for docetaxel efficacy, in the BIG 2-98 and using a pooled analysis of three other randomised trials. Patients and methods: 2887 patients were randomly assigned in a 2 x 2 trial design to one of four treatments. The primary objective was to evaluate the overall efficacy of docetaxel on disease free su…
Assessing the impact of CMF-like/Anthracycline-based/Anthracycline-Taxane-based/dose-dense chemotherapy in dependency of positive axillary lymph node…
2014
Abstract Aim Adjuvant chemotherapy has changed dramatically in the last decades. Anthracycline-/Taxane-based and dose-dense chemotherapy regimens improved survival in node positive breast cancer. This study tries to answer the following questions: (1)Are there differences in survival dependent on chemotherapy regimens in stratified by number of positive lymph nodes/grading (G)/hormone receptor-status (HR)/T-stage? (2)Is it possible to attribute these effects to chemotherapy by only investigating patients who received 100% guideline-conform surgery, radiotherapy and endocrine therapy? Methods This is a German multi-centre (17 participating hospitals all certified as breast cancer centres) re…
Neoadjuvant bevacizumab and anthracycline-taxane-based chemotherapy in 678 triple-negative primary breast cancers; results from the geparquinto study…
2013
Abstract Background We evaluated the pathological complete response (pCR) rate after neoadjuvant epirubicin, (E) cyclophosphamide (C) and docetaxel containing chemotherapy with and without the addition of bevacizumab in patients with triple-negative breast cancer (TNBC). Patients and methods Patients with untreated cT1c-4d TNBC represented a stratified subset of the 1948 participants of the HER2-negative part of the GeparQuinto trial. Patients were randomized to receive four cycles EC (90/600 mg/m2; q3w) followed by four cycles docetaxel (100 mg/m2; q3w) each with or without bevacizumab (15 mg/kg; q3w) added to chemotherapy. Results TNBC patients were randomized to chemotherapy without (n =…
The Impact of Age on Quality of Life in Breast Cancer Patients Receiving Adjuvant Chemotherapy: A Comparative Analysis From the Prospective Multicent…
2016
Elderly breast cancer patients are affected by poorer quality of life (QoL) compared to younger patients. Because QoL has a relevant impact on guideline-adherent treatment, elderly breast cancer patients are often undertreated, especially with regard to adjuvant chemotherapy, and overall survival is decreased. Thus, understanding the impact of chemotherapy on QoL in elderly patients is crucial. This study compared QoL in patients aged 65 years and 65 to 70 years receiving adjuvant chemotherapy as a secondary outcome in the prospective randomized multicenter ADEBAR trial.Patients with lymph node-positive breast cancer were prospectively randomized for either sequential anthracycline-taxane o…
The natural history of breast carcinoma in patients withor = 10 metastatic axillary lymph nodes before and after the advent of adjuvant therapy: a mu…
2005
BACKGROUND The majority of patients with breast carcinoma with ≥ 10 metastatic axillary lymph nodes (ALNs) develop recurrent disease within 5 years from diagnosis. The purpose of the current study, performed retrospectively, was to characterize the natural history of this subset of patients, both before and after the advent of adjuvant anthracycline-based chemotherapy and tamoxifen. METHODS Retrospectively, patients with primary breast carcinoma (N = 882) with ≥ 10 metastatic ALNs, treated between 1954 and 1998, were selected from 3 institutions: The University of Texas M. D. Anderson Cancer Center (Houston, TX); the Institut Gustave Roussy (Villejuif, France); and Hospital Clinico Universi…
Nine weeks versus 1 year adjuvant trastuzumab in combination with chemotherapy: final results of the phase III randomized Short-HER study
2018
Background: Chemotherapy plus 1-year trastuzumab is the standard adjuvant treatment of HER2-positive breast cancer. The efficacy of less extended trastuzumab exposure is under investigation. The short-HER study was aimed to assess the non-inferiority of 9 weeks versus 1 year of adjuvant trastuzumab combined with chemotherapy. Patients and methods: HER2-positive breast cancer patients with node-positive or, if node negative, with at least one risk factor (pT>2 cm, G3, lympho-vascular invasion, Ki-67 > 20%, age 35 years, or hormone receptor negativity) were randomly assigned to receive sequential anthracycline-taxane combinations plus 1-year trastuzumab (arm A, long) or plus 9 weeks tra…
Carboplatin and pegylated liposomal doxorubicin for advanced ovarian cancer. Preliminary activity results of the MITO-2 phase III trial
2008
<i>Background:</i> Based on the efficacy of pegylated liposomal doxorubicin (PLD) in relapsed ovarian cancer, we are conducting a phase III study comparing carboplatin plus either paclitaxel or PLD as first-line therapy in advanced ovarian cancer. Because of limited phase I and II data on PLD plus carboplatin in this setting, we conducted an interim activity analysis. <i>Patients and Methods:</i> Patients with stage 1c-IV epithelial ovarian cancer were randomized to carboplatin AUC 5 plus either paclitaxel 175 mg/m<sup>2</sup> or PLD 30 mg/m<sup>2</sup> every 3 weeks for 6 cycles. The interim activity analysis was planned according to a single…
A systematic review and meta-analysis of the impact of WT1 polymorphism rs16754 in the effectiveness of standard chemotherapy in patients with acute …
2015
The polymorphism rs16754 of the WT1 gene has been described as a possible prognostic marker in different acute myeloid leukemia (AML) cohorts; however, it is not supported by all the studies. We performed the first meta-analysis evaluating the effect of this polymorphism upon the effectiveness of standard AML therapy. Fourteen cohort studies were included (3618 patients). Patients with the variant allele showed a significant higher overall survival (OS) at 5 years (OR: 1.24, 95% CI: 1.06-1.45, P = 0.007, with dominant model). WT1 did not influence complete remission, but a higher disease-free survival was observed with the variant allele. In the subgroup analysis, Caucasians, pediatric and …
Cardiac Glycosides Exert Anticancer Effects by Inducing Immunogenic Cell Death
2012
Some successful chemotherapeutics, notably anthracyclines and oxaliplatin, induce a type of cell stress and death that is immunogenic, hence converting the patient's dying cancer cells into a vaccine that stimulates antitumor immune responses. By means of a fluorescence microscopy platform that allows for the automated detection of the biochemical hallmarks of such a peculiar cell death modality, we identified cardiac glycosides (CGs) as exceptionally efficient inducers of immunogenic cell death, an effect that was associated with the in- hibition of the plasma membrane Na + - and K + -dependent adenosine triphosphatase (Na + /K + -ATPase). CGs ex- acerbated the antineoplastic effects of DN…
A Stereochemically Driven Supramolecular Polymerisation
2018
Anthracyclines self-assemble in water into dimers. In the presence of sufficiently high salt (NaCl) concentrations, solutions of the antibiotic doxorubicin, but not those of the closely related molecules daunomycin and epirubicin, turn into gels barely compatible with the presence of small oligomers. The use of spectroscopic, scattering, imaging and computational techniques, allowed light to be shed on the self-assembly process that triggered doxorubicin gelification. A complex picture emerged, with doxorubicin molecules assembled into long, highly chiral, supramolecular aggregates made of hundreds of units, showing redshifted fluorescence spectra, very short fluorescence lifetimes and smal…
