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…

FcγRIIa and Fc γ RIIIa Polymorphisms and Cetuximab Benefit in the Microscopic Disease

2014

Abstract Purpose: FcγR polymorphisms have been reported to enhance the immune-mediated effects of cetuximab in metastatic colorectal cancer. There are no data on the relationship between these polymorphisms and cetuximab in the early-stage setting. We performed a pharmacogenomic analysis of EXPERT-C, a randomized phase II trial of neoadjuvant CAPOX followed by chemoradiotherapy, surgery, and adjuvant CAPOX ± cetuximab in high-risk, locally advanced rectal cancer. Experimental Design: FcγRIIa-H131R and FcγRIIIa-V158F polymorphisms were analyzed on DNA from peripheral blood samples. Kaplan–Meier method and Cox regression analysis were used to calculate survival estimates and compare treatment…

ErbB-3 predicts survival in ovarian cancer.

2006

Background HER3 (erbB-3) is a member of the epidermal growth factor receptor (EGFR) family. After dimerization with other members of the EGFR family several signal transduction cascades can be activated, including phosphoinosite 3′-kinase (PI3-K)/Akt and extracellular signal-regulated kinase (ERK1/2). Here, we studied a possible association between HER3 expression and prognosis in patients with ovarian cancer. Methods Tumor tissue of 116 consecutive patients diagnosed with primary epithelial ovarian cancer between 1986 and 1995 was analyzed immunohistochemically for HER3 expression. A possible influence of HER3 expression on survival was studied by multivariate Cox regression adjusting for …

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…

Do multiple oestrogen receptor assays give significant additional information for the management of breast cancer?

1989

In 101 breast cancer patients, measurement of oestrogen receptor status in multiple biopsies across a tumour reveals a highly significant difference in the proportion of patients remaining either disease-free (P less than 0.04) or alive (P less than 0.005), when those with uniformly receptor positive (++) primary tumours are matched with clinically comparable patients whose tumours were homogeneously receptor negative (--). Mean follow-up time was 85 months. The prognostic value of this discriminant is particularly striking in the 53 patients with involved nodes at presentation. Of these, 13 were (++) and seven remain alive of whom six are disease-free, whereas 24 of the 29 (--) patients ar…

Cooperative studies of chemoprophylaxis after transurethral resection of bladder tumors

1983

Large cooperative trials are more likely than series studied by small groups to bring about significant progress in the field of intravesical adjuvant chemotherapy of superficial bladder tumor. Multicenter randomized trials involving large numbers of patients have been conducted in Europe by the EORTC Urological Group. The Group's main objectives were to compare the efficacy of thio-TEPA, VM-26, epodyl, Adriamycin, and cisplatin, against no treatment, and to study the prophylactic effect of oral pyridoxine and evaluate the main prognostic factors. The results obtained so far are reported. Preliminary information is also given about the Blinst study, a multicenter open investigation of local…

Prognostic vs predictive molecular biomarkers in colorectal cancer: is KRAS and BRAF wild type status required for anti-EGFR therapy?

2010

An important molecular target for metastatic CRC treatment is the epidermal growth factor receptor (EGFR). Many potential biomarkers predictive of response to anti-EGFR monoclonal antibodies (cetuximab and panitumumab) have been retrospectively evaluated, including EGFR activation markers and EGFR ligands activation markers. With regard to the "negative predictive factors" responsible for primary or intrinsic resistance to anti-EGFR antibodies a lot of data are now available. Among these, KRAS mutations have emerged as a major predictor of resistance to panitumumab or cetuximab in the clinical setting and several studies of patients receiving first and subsequent lines of treatment have sho…

Molecular markers and biological targeted therapies in metastatic colorectal cancer: expert opinion and recommendations derived from the 11th ESMO/Wo…

2010

The article summarizes the expert discussion and recommendations on the use of molecular markers and of biological targeted therapies in metastatic colorectal cancer (mCRC), as well as a proposed treatment decision strategy for mCRC treatment. The meeting was conducted during the 11th ESMO/World Gastrointestinal Cancer Congress (WGICC) in Barcelona in June 2009. The manuscript describes the outcome of an expert discussion leading to an expert recommendation. The increasing knowledge on clinical and molecular markers and the availability of biological targeted therapies have major implications in the optimal management in mCRC. 21 Suppl 6 vi1 10
