Abstract OT-31-01: A phase II study to evaluate the efficacy and safety of pembrolizumab plus carboplatin in BRCA-related metastatic breast cancer: P…
2021
Abstract Background Considering the high proportion of tumor-infiltrating lymphocytes (TILs) in BRCA-related breast cancer, we expect that PD-1 pathway is highly expressed and PD-1 antagonist pembrolizumab could provide clinical activity in this kind of tumor. Furthermore, BRCA-related breast cancers are known to be more sensitive to platinum-derived drugs. Thus the association between Pembrolizumab and Carboplatin in metastatic BRCA-related breast cancer seems to be active in this setting of patients. This study will evaluate the safety and the efficacy of Pembrolizumab associated with Carboplatin in BRCA mutated or with unknown mutations metastatic breast cancer patients. Study and Statis…
Abstract P2-05-04: Gene expression associated with poor prognosis of young TNBC patients
2015
Abstract Background: Among TNBC patients those of very young age (<40 years) display a significantly worse prognosis (Liedtke et al. 2013 Breast Cancer Res Treat). We verified this result in 1161 TNBC samples with full Affymetrix gene expression data of which 845 patients had both detailed age and follow up information. Materials and Methods: We split the full sample set into a finding cohort of 394 TNBC and a validation cohort of 767 TNBC encompassing 309 and 536 samples, respectively, with both age and follow up data. We then used significance analysis of microarrays (SAM) in the finding cohort to look for genes whose expression is associated with young age (<40 years). Iden…
The role of surgery in patients with primary metastatic breast cancer (PMBC) receiving monoclonal antibody treatment.
2014
1097 Background: Apart from the individual palliative need, the beneficial effect of surgically removing the primary tumor in PMBC on long-term outcomes, as suggested by retrospective series and me...
Metronomic chemotherapy (mCHT) in metastatic triple-negative breast cancer (TNBC) patients: results of the VICTOR-6 study
2021
Abstract Purpose Triple-negative breast cancer (TNBC) represents a subtype of breast cancer which lacks the expression of oestrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER2): TNBC accounts for approximately 20% of newly diagnosed breast cancers and is associated with younger age at diagnosis, greater recurrence risk and shorter survival time. Therapeutic options are very scarce. Aim of the present analysis is to provide further insights into the clinical activity of metronomic chemotherapy (mCHT), in a real-life setting. Methods We used data included in the VICTOR-6 study for the present analysis. VICTOR-6 is an Italian multicentre retrosp…
G-CSF dosing schedule to prevent eribulin-induced neutropenia: Can modelling and simulation help?
2015
e20673 Background: Eribulin is a microtubule inhibitor indicated for the treatment of patients with metastatic breast cancer and should be administered on day 1 and 8 of each 21-day cycle. Neutrope...
Impact of deleterious variants in other genes beyond BRCA1/2 detected in breast/ovarian and pancreatic cancer patients by NGS-based multi-gene panel …
2021
Background Hereditary breast cancer (BC), ovarian cancer (OC), and pancreatic cancer (PC) are the major BRCA-associated tumours. However, some BRCA1/2-wild-type (wt) patients with a strong personal and/or family history of cancer need a further genetic testing through a multi-gene panel containing other high- and moderate-risk susceptibility genes. Patients and methods Our study was aimed to assess if some BC, OC, or PC patients should be offered multi-gene panel testing, based on well-defined criteria concerning their personal and/or family history of cancer, such as earliness of cancer onset, occurrence of multiple tumours, or presence of at least two or more affected first-degree relativ…
Do BARD1 Mutations Confer an Elevated Risk of Prostate Cancer?
2021
Simple Summary Current cancer testing gene panels tend to be comprehensive. One of the genes commonly included in the testing panels is BARD1. To establish whether BARD1 mutations predispose to prostate cancer, we sequenced BARD1 in 390 hereditary prostate cancer cases, genotyped 5715 men with unselected prostate cancer and 10,252 controls for three recurrent rare BARD1 variants in Poland. We did not see an elevated prostate risk cancer given p.Q564X truncating mutation, p.R658C missense mutation and p.R659= synonymous variant. Neither variant influenced prostate cancer characteristics or survival. Our study is the first to evaluate the association between BARD1 mutations and prostate cance…
Immunoglobulin Kappa C Has Independent Prognostic Significance in Node-Negative Breast Cancer.
2009
Abstract Background: Utilizing microarray based gene-expression analysis of fresh-frozen tissue we could recently demonstrate the prognostic impact of a B cell metagene in node-negative breast cancer (Cancer Res 68: 5405-5413, 2008). In the present study we investigated the prognostic significance of immunoglobulin kappa c (IGKC) in formalin-fixed paraffin embedded (FFPE) breast cancer specimens of 363 node-negative breast cancer patients which were not treated in the adjuvant setting.Methods: RT-PCR was used to analyze mRNA expression of IGKC in FFPE tissue of 363 patients with node-negative breast cancer. Additionally to IGKC we examined the prognostic impact of age, histological grade, t…
Role of MTHFR (677, 1298) haplotype in the risk of developing secondary leukemia after treatment of breast cancer and hematological malignancies
2007
Therapy-related myelodysplasia and acute myeloid leukemia (t-MDS/AML) is a malignancy occurring after exposure to chemotherapy and/or radiotherapy. Polymorphisms involved in chemotherapy/radiotherapy response genes could be related to an increased risk of developing this neoplasia. We have studied 11 polymorphisms in genes of drug detoxification pathways (NQO1, glutathione S-transferase pi) and DNA repair xeroderma pigmentosum, complementation group (3) (XPC(3), X-ray repair cross complementing protein (1)), Nijmegen breakage syndrome (1), excision repair cross-complementing rodent repair deficiency, complementation group (5) and X-ray repair cross complementing protein (3) and in the methy…
Trastuzumab treatment in patients with advanced breast cancer (ABC) confined to locoregional and skeletal sites: Results from a large nonintervention…
2012
640 Background: In a prospective observation study routine trastuzumab (T) treatment in HER2+ ABC was evaluated in a total of 1,687 patients (pts) since 2001. This large number allows the subgroup analysis of patients with the involvement of specific sites. Methods: Information on extent of advanced disease was available in 1,674 pts (99%) with HER2 overexpressing ABC. Pts were either pre-treated (39%) or naïve to palliative chemotherapy (CT). The following subgroups and their characteristics were analysed: I: locally ABC only; II: bone metastases allowing for concomitant local tumour; III: other. Results: Locally advanced lesions were found to be the sole BC manifestation in 145 pts (8.7%…
