A fully synthetic glycopeptide antitumor vaccine based on multiple antigen presentation on a hyperbranched polymer.
2014
For antitumor vaccines both the selected tumor-associated antigen, as well as the mode of its presentation, affect the immune response. According to the principle of multiple antigen presentation, a tumor-associated MUC1 glycopeptide combined with the immunostimulating T-cell epitope P2 from tetanus toxoid was coupled to a multi-functionalized hyperbranched polyglycerol by "click chemistry". This globular polymeric carrier has a flexible dendrimer-like structure, which allows optimal antigen presentation to the immune system. The resulting fully synthetic vaccine induced strong immune responses in mice and IgG antibodies recognizing human breast-cancer cells.

Automatic Seed Placement for Breast Lesion Segmentation on US Images
2012
Breast lesion boundaries have been mostly extracted by using conventional approaches as a previous step in the development of computer-aided diagnosis systems. Among these, region growing is a frequently used segmentation method. To make the segmentation completely automatic, most of the region growing methods incorporate automatic selection of the seed points. This paper proposes a new automatic seed placement algorithm for breast lesion segmentation on ultrasound images by means of assigning the probability of belonging to a lesion for every pixel depending on intensity, texture and geometrical constraints. The proposal has been evaluated using a set of sonographic breast images with acco…
Lesion Segmentation in Breast Sonography
2010
Sonography is gaining popularity as an adjunct screening technique for assessing abnormalities in the breast This is particularly true in cases where the subject has dense breast tissue, wherein widespread techniques like Digital Mammography (DM) fail to produce reliable outcomes This article proposes a novel and fully automatic methodology for breast lesion segmentation in B-mode Ultra-Sound (US) images by utilizing region, boundary and shape information to cope up with the inherent artifacts present in US images The proposed approach has been evaluated using a set of sonographic images with accompanying expert-provided ground truth.
A randomized, open-label, multicentre, phase IV study evaluating palbociclib plus endocrine treatment versus a chemotherapy based treatment strategy …
2017
TPS1115 Background: Although endocrine based therapy is recommended as first-line treatment in metastatic breast cancer (MBC) in patients with an HER2-/HR+ tumour up to 50% of the patients receive chemotherapy. Palbociclib (P) a CDK4/6 inhibitor improves PFS by 42% in endocrine sensitive and resistant HER2-/HR+ MBC when added to an endocrine therapy (ET). Patients included in clinical trials are often criticised not to be representative for real world breast cancer patients. Methods: Patients with first-line HER2-/HR+ MBC who are candidate for mono-chemotherapy will be eligible to be randomised 1:1 to receive either P plus ET per label or mono-chemotherapy per investigator´s choice with or…
German Adjuvant Intergroup Node Positive (GAIN) study: A phase III trial to compare IDD-ETC versus EC-TX in patients with node-positive primary breas…
2014
1009 Background: Intense dose-dense (idd) epirubicin (E), paclitaxel (T), cyclophosphamide (C) (idd-ETC) resulted in a superior disease-free (DFS) and overall survival (OS) compared to conventional...
The effect of obesity on prognosis in operable breast cancer patients treated with adjuvant anthracyclines and taxanes according to pathologic subtyp…
2013
1031 Background: According to observational studies, obesity is an unfavourable prognostic factor in breast cancer (BC), regardless of menopausal status and treatment received. Information collected in clinical trials should confirm this effect and serves to test its homogeneity by pathologic subtype. Methods: We retrospectively analysed 5,683 operable BC patients enrolled in four randomized clinical trials (GEICAM/9906, 9805, 2003–02, and BCIRG 001) evaluating adjuvant anthracyclines and taxanes. Our primary aim was to assess the prognostic effect of body mass index (BMI) on disease recurrence, breast cancer mortality (BCM), and overall mortality (OM). A secondary aim was to detect differ…
Abstract CT020: MERIT: introducing individualized cancer vaccines for the treatment of TNBC - a phase I trial
2016
Abstract The majority of metastatic cancers remain incurable since the current methods of treatment often fail to target the heterogeneous nature of each individual patient's tumor. Personalized approaches targeting each individual patient's tumor may therefore bring significant improvements. The Mutanome Engineered RNA Immuno-Therapy (MERIT) consortium will clinically validate a pioneering RNA-based immunotherapy concept for the treatment of triple negative breast cancer (TNBC) by targeting shared tumor antigens and individual neo-antigens in TNBC patients. MERIT combines two personalized treatment concepts: (i) treatment with vaccines containing “off-the-shelf” mRNAs selected from a pre-s…
Outcome Prediction in Node-Negative Breast Cancer Based on ASCO-Recommended Biomarkers uPA/PAI-1 Using the Final 10-Year Analysis of the Randomized M…
2009
Abstract Background: Based on interim analysis of Chemo N0, the first prospective multicenter randomized clinical trial using biomarkers uPA/PAI-1 for risk stratification and chemotherapy selection in N0 breast cancer, uPA/PAI-1 are now recommended for routine use by ASCO and AGO guidelines. Final 10-year follow-up of Chemo N0 has validated the clinically relevant long-term prognostic and predictive impact of uPA/PAI-1 in N0 breast cancer. To quantify the clinical utility of this impact, outcomes in subgroups defined by these biomarkers were compared to predictions of Adjuvant Online™, the leading validated tool based on established clinical factors. Methods: In Chemo N0, patients (n=647, 1…
