Adjuvant cisplatin-based chemoradiation improves survival in HNSCC patients presenting with risk features. ERCC1 (excision repair cross-complementation group 1) is associated with resistance to chemo- and radiation therapy and may have a prognostic value in HNSCC patients. Here we studied ERCC1 expression and the polymorphism T19007C as prognostic markers(More)
AIMS Fos-related antigen 1 (Fra-1) is a member of the activator protein 1 (AP-1) transcription factor family. Our objective was to evaluate the role of Fra-1 expression in breast carcinoma progression and prognosis. METHODS AND RESULTS Fra-1 expression was investigated by immunohistochemistry in two tissue microarrays containing, respectively, 85 ductal(More)
A detailed genome mapping analysis of 213,636 expressed sequence tags (EST) derived from nontumor and tumor tissues of the oral cavity, larynx, pharynx, and thyroid was done. Transcripts matching known human genes were identified; potential new splice variants were flagged and subjected to manual curation, pointing to 788 putatively new alternative splicing(More)
BACKGROUND Transforming growth factor beta1 (TGFbeta1) is a negative growth regulator in keratinocytes, and in vitro studies lead to the concept that loss of TGFbeta1 responsiveness is a critical step in epithelial carcinogenesis. OBJECTIVE To investigate the prognostic relevance of TGFbeta1 expression in head and neck squamous cell carcinoma (HNSCC). (More)
This study aimed to identify the CD24 and CD44 immunophenotypes within invasive ductal breast carcinoma (IDC) subgroups defined by immunohistochesmistry markers and to determine its influence on prognosis as well as its association with the expression of Ki-67, cytokeratins (CK5 and CK18) and claudin-7.(More)
BACKGROUND A balance between urokinase-type plasminogen activator (uPA) and its main inhibitor type-1 (PAI-1) appears to be important for cancer invasive behavior. Since uPA/PAI-1 system seems to be regulated by transforming growth factor beta1 (TGFbeta1) in different cell types, our aim was to investigate the relationship between the expression of the(More)
OBJECTIVES To explore the prognostic role of plasma levels of osteopontin (OPN), a phosphoglycoprotein with adhesive properties, in patients with head and neck squamous cell carcinoma (HNSCC) undergoing concomitant chemoradiotherapy. Previous studies have proposed OPN level as a prognostic factor in several cancers. DESIGN Prospective analysis of plasma(More)
Epithelial to mesenchymal transition (EMT) is a process implicated in cancer progression in which the underlying cellular changes have been identified mainly using in vitro models. We determined the expression of some putative EMT biomarkers including E-cadherin, beta-catenin, zinc finger factor Snail (Snail), transforming growth factor beta1 (TGFbeta1),(More)
The TNM Classification of Malignant Tumours (TNM) staging system is the primary means of determining a prognosis for gastric adenocarcinoma (GC). However, tumor behavior in the individual patient is unpredictable and in spite of treatment advances, a classification of 'advanced stage' still portends a poor prognosis. Thus, further insights from molecular(More)
BACKGROUND Previous knowledge of cervical lymph node compromise may be crucial to choose the best treatment strategy in oral squamous cell carcinoma (OSCC). Here we propose a set four genes, whose mRNA expression in the primary tumor predicts nodal status in OSCC, excluding tongue. MATERIAL AND METHODS We identified differentially expressed genes in OSCC(More)
