Biomarkers of benefit from cetuximab-based therapy in metastatic colorectal cancer: Interaction of EGFR ligand expression with RAS/RAF, PIK3CA genotypes
(2013)Background: More than half of patients with KRAS-wild type advanced colorectal cancer (CRC) fail anti-EGFR monoclonal antibodies. We studied EGFR-axis messenger RNA (mRNA) expression and RAS, RAF, PIK3CA mutations in order ...

Economic recession and emergence of an HIV-1 outbreak among drug injectors in Athens metropolitan area: A longitudinal study
(2013)Background: During 2011, a dramatic increase (1600%) of reported HIV-1 infections among injecting drug users (IDUs) was noted in Athens, Greece. We herein assess the potential causal pathways associated with this outbreak. ...

KRAS, NRAS and BRAF mutations in Greek and Romanian patients with colorectal cancer: A cohort study
(2014)Objectives: Treatment decision-making in colorectal cancer is often guided by tumour tissue molecular analysis. The aim of this study was the development and validation of a high-resolution melting (HRM) method for the ...

Mutational profiling of the RAS, PI3K, MET and b-catenin pathways in cancer of unknown primary: a retrospective study of the Hellenic Cooperative Oncology Group
(2014)Cancer of unknown primary origin (CUP) had a poor prognosis, determined by clinico-histological characteristics, partly due to the lack of insights on its biology. We screened tumour DNA from 87 patients with CUP for CTNNB1 ...

Prognostic utility of angiogenesis and hypoxia effectors in patients with operable squamous cell cancer of the larynx
(2012)Angiogenesis is active in localised laryngeal squamous cell carcinoma. We assessed relative messenger RNA (mRNA) and immunohistochemical (IHC) expression of Vascular Endothelial Growth Factors (VEGF) A, B, C, their receptors ...

A twisted kiss: In vitro and in vivo evidence of genetic variation and suppressed transcription of the metastasis-suppressor gene KiSS1 in early breast cancer
(2010)KiSS-1 is a metastasis suppressor gene, its inactivation linked to advanced tumor stage and dismal prognosis. We studied its mutational status, transcription and protein expression in human cancer cell lines and patients ...
