Cancer of Unknown Primary origin in the genomic era: Elucidating the dark box of cancer
(2015)Cancer of Unknown Primary (CUP) comprises a heterogeneous disease group with diagnosis of metastatic malignancy in the absence of an identifiable primary site after diagnostic work up. CUP may either resemble a specific ...

Article
Cancer of unknown primary site: Missing primary or missing biology?
(2007)Cancer of unknown primary site (CUP) ranks as the fourth most common cause of cancer deaths and represents both a diagnostic and a management challenge. In CUP, the regression or dormancy of the primary tumor, the development ...

Gene expression of estrogen receptor, progesterone receptor and microtubule-associated protein Tau in high-risk early breast cancer: A quest for molecular predictors of treatment benefit in the context of a Hellenic Cooperative Oncology Group trial
(2009)Background Estrogen receptor (ER) and progesterone receptor (PgR) protein expression carry weak prognostic and moderate predictive utility for the outcome of early breast cancer patients on adjuvant chemohormonotherapy. ...

Article
Improved outcome of high-risk early HER2 positive breast cancer with high CXCL13-CXCR5 messenger RNA expression
(2012)Background: Chemokines are important in cell migration and are thought to play a key role in metastasis. We explored the prognostic significance of C-X-C ligand-motif (CXCL) 12, CXCL13, and receptor (CXCR) 5 on disease-free ...

Article
Management of leptomeningeal malignancy
(2005)Leptomeningeal carcinomatosis is defined as malignant infiltration of the pia matter and arachnoid membrane. Leukaemias and lymphomas, lung, breast cancer and melanoma are the primary tumours commonly associated with ...

Prognostic significance of RACGAP1 mRNA expression in high-risk early breast cancer: A study in primary tumors of breast cancer patients participating in a randomized Hellenic Cooperative Oncology Group trial
(2013)Purpose: RACGAP1 is a Rac GTPase-activating protein involved in cell growth regulation, cell transformation and metastasis. The aim of the present study was to explore the prognostic and/or predictive significance of RACGAP1 ...

Article
Prognostic significance of UBE2C mRNA expression in high-risk early breast cancer. A hellenic cooperative oncology group (HECOG) study
(2012)Background: The ubiquitin-proteasome system (UPS) plays a pivotal role in tumorigenesis. Components of the UPS have recently been implicated in breast cancer progression. In the present study, we sought to explore the ...

Article
Prognostic utility of β-tubulin isotype III and correlations with other molecular and clinicopathological variables in patients with early breast cancer: A translational Hellenic Cooperative Oncology Group (HeCOG) study
(2011)We evaluated the prognostic and predictive utility of β-tubulin isotype III (TUBB3) tumour gene transcription in early breast cancer patients enrolled in a randomised study. Quantitative reverse transcription-polymerase ...

Article
Survivin and glycodelin transcriptional activity in node-positive early breast cancer: mRNA expression of two key regulators of cell survival
(2006)Introduction: Glycodelin and survivin are key polypeptide regulators of cellular proliferation, apoptosis and angiogenesis. In view of contradictory reports on their functional role in tumors, we studied their transcriptional ...

Article
Transcriptional activity of human epidermal growth factor receptor family and angiogenesis effectors in locoregionally recurrent head and neck squamous cell carcinoma and correlation with patient outcome
(2009)Locoregional recurrence is the most common failure pattern in patients with head and neck squamous cell carcinoma (HNSCC). We retrospectively identified 41 HNSCC patients with locoregional relapse and used kinetic reverse ...

Article
Triple-negative phenotype is of adverse prognostic value in patients treated with dose-dense sequential adjuvant chemotherapy: A translational research analysis in the context of a Hellenic Cooperative Oncology Group (HeCOG) randomized phase III trial
(2012)Purpose: It is well recognized that breast cancer is a heterogeneous disease. The purpose of the current study was to classify patients according to the immunohistochemical phenotype of their tumors in an effort to evaluate ...

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 ...
