Subcutaneous trastuzumab therapy for HER2-positive early breast cancer in the routine clinical practice: First interim analysis of the National Non-I…

2016

581Background: In 2013 a subcutaneous (SC) formulation of trastuzumab (T) was approved based on non-inferiority to intravenous (IV) T as proven in the HannaH trial. So far no data from the routine ...

Abstract PD5-2: Ph1b study of the PI3K inhibitor taselisib (GDC-0032) in combination with letrozole in patients with hormone receptor-positive advanc…

2015

Abstract Background: Taselisib (GDC-0032) is a next-generation PI3K inhibitor with increased anti-tumor activity against PIK3CA mutant (MT) cancers. Taselisib is an orally bioavailable, potent, and selective inhibitor of Class I PI3K alpha, delta, and gamma isoforms, with 30-fold less inhibition of the PI3K beta isoform relative to the PI3K alpha isoform. Preclinical data show that taselisib has enhanced activity against PI3K alpha isoform (PIK3CA) MT breast cancer cell lines and enhanced antitumor activity when combined with letrozole. Clinical data with single-agent taselisib also showed increased tumor shrinkage in patients with PIK3CA MT breast cancer as compared to patients with PIK3CA…

Abstract Background: Breast cancer (BC) is the most frequent tumor in women worldwide. BC lethality is caused by aggressive, therapy-resistant metastases (mBC). Preliminary data have shown that mBC lesions are invariably embedded into a densely packed network of fibrous extracellular matrix, making the metastatic microenvironment a potent inducer of mechanical inputs, ultimately leading to the activation of the transcription factors YAP/TAZ. Aberrant mechano-signaling could thus represent a vulnerability of metastasis, which can be exploited to develop new therapeutic strategies. To investigate how metastatic outgrowth is regulated by the physical properties of the microenvironment, and how…

A prognostic miRNA based signature in early-stage HER2-positive breast cancer patients.

2021

e12600 Background: In early-stage HER2+ breast cancer (BC), escalation or de-escalation of systemic treatment is an unmet need. Integration of promising biomarkers into risk scoring will further help progressing in the field. We aim to develop a prognostic signature that integrates two miRNAs (A and B) and quantitative and qualitative clinical variables in patients diagnosed with HER2+ BC. Methods: This study was conducted in a retrospective cohort of 45 HER2+ BC patients. Patients received standard treatment for localized disease. We calculated a prognostic signature for disease-free survival (DFS) using principal components analysis for mixed data combining clinicopathological data (Ki67…

Abstract CT201: The Mutanome Engineered RNA Immuno-Therapy (MERIT) project

2015

Abstract The Mutanome Engineered RNA Immuno-Therapy (MERIT) consortium will clinically and industrially validate a pioneering RNA-based immunotherapy concept that targets individual tumor antigens and tumor-specific mutations in triple negative breast cancer (TNBC) patients. This biomarker-guided, personalized therapy is a collaborative effort of five partners from academia and industry and is funded by the European Commission's FP7 and led by BioNTech AG. TNBC is an aggressive, molecularly heterogeneous cancer that accounts for 20% of all breast cancer patients. The 5-year survival rate is less than 80%. The molecular heterogeneity across TNBCs results in a lack of common targetable molecu…

A statistical approach to an individualized prognostic index (IPI) for breast cancer survivability

1983

The authors present 611 and 262 case histories of patients with breast cancer, studied 5 and 10 years after mastectomy, respectively; 27 clinical and 10 histologic parameters were considered for the statistical evaluation, in order to define an Individualized Prognostic Index (IPI) for breast cancer survivability. The probability of survival was estimated by a Bayesian formula using selected prognostic parameters, these parameters were placed in order of discriminant resolution and, for the calculation of the IPI, were selected according to their importance, as it follows: 5 years after surgery: percent affected nodules, dermal infiltration, TNM phase, Scarff-Bloom index and evolutive outbr…

Freedom from progression (FFP) by adding paclitaxel (T) to doxorubicin (A) followed by CMF as adjuvant or primary systemic therapy: 10-yr results of …

2013

537 Background: At the time the ECTO was designed in 1996, taxanes were only indicated for patients with metastatic breast cancer. However, paclitaxel and docetaxel were still to be tested in the adjuvant setting. In addition there was relatively scarce information on the comparative efficacy of neoadjuvant and adjuvant regimens. The ECTO trial was designed to evaluate the addition of paclitaxel to an anthracycline-based adjuvant regimen and to compare this combination with the same regimen given as primary systemic (neoadjuvant) therapy. Methods: A total of 1,355 women with operable breast cancer were randomized to one of three treatments: 1) surgery followed by adjuvant single agent doxo…

Circulating miR-30b-5p levels in plasma as a novel potential biomarker for early detection of breast cancer

2021

Background Recently, microRNAs have been demonstrated to be potential non-invasive biomarkers for diagnosis, prognosis assessment or prediction of response to treatment in cancer. In this study, we evaluate the potential of miR-30b-5p as a biomarker for early diagnosis of breast cancer (BC) in tissue and plasma. Methods Expression of miR-30b-5p was determined in a series of 112 BC and 40 normal breast tissues. Circulating miR-30b-5p levels in plasma samples were determined in a discovery cohort of 38 BC patients and 40 healthy donors and in a validation cohort of 83 BC patients and 83 healthy volunteers. miR-30b-5p expression was measured by quantitative real-time PCR and receiver operating…
