MicroRNAs are aberrantly expressed and correlate with tumourigenesis and the progression of solid tumours. The miR-200 family determines the epithelial phenotype of cancer cells and regulates invasiveness and migration. Thus, we hypothesised that the quantitative detection of the miR-200 family as epithelial-specific microRNAs in the blood could be a useful(More)
PURPOSE To determine the efficacy of the addition of gefitinib to raltitrexed in patients with colorectal cancer (CRC) that have progressed after first line chemotherapy. The study also sought to explore the safety of the combination and to investigate biomarkers predictive outcome. METHODS A total of 76 patients were randomized to raltitrexed (3 mg/m(2)(More)
BACKGROUND In the MACRO study, patients with metastatic colorectal cancer (mCRC) were randomised to first-line treatment with 6 cycles of capecitabine and oxaliplatin (XELOX) plus bevacizumab followed by either single-agent bevacizumab or XELOX plus bevacizumab until disease progression. An additional retrospective analysis was performed to define the(More)
The presence of tumor cells in the bone marrow (BM) could be relevant to identifying high risk of disease progression and death in gastrointestinal cancer. However, the molecular profile associated with disseminated tumor cells (DTCs) homing to the BM has yet to be defined. MicroRNAs (miRNA) play key roles in cellular processes implicated in cancer. Thus,(More)
BACKGROUND This study aims to assess Plakophilin-3 (PKP3) as a surrogate biomarker of circulating tumor cells in patients with gastrointestinal cancer. METHODS The primary aim is to estimate the diagnostic accuracy of PKP3 real-time reverse transcriptase-PCR in blood. Receiver operating characteristic curves were constructed. Correlations between the(More)
INTRODUCTION Hand-foot syndrome (HFS) is a limiting toxicity of capecitabine, which is not life-threatening but could compromise capecitabine efficacy. MATERIALS AND METHODS This phase II, multicenter, non-controlled study assessed the safety, particularly grade three HFS incidence, and efficacy of four capecitabine-based chemotherapy regimens(More)
BACKGROUND Irinotecan plus infusional 5-fluorouracil/leucovorin (FOLFIRI) is accepted as a reference treatment for the first-line treatment of patients with metastatic colorectal cancer (MCRC). The aim of this study was to demonstrate that a regimen without leucovorin (LV) (FUIRI) is not inferior to the standard FOLFIRI (response rate). PATIENTS AND(More)
AIM To analyze GDF15 and MMP7 serum levels as diagnostic biomarkers in gastric cancer (GC) patients. The prognostic value of GDF15 and MMP7 serum levels in combination with miR-200c blood expression was also analyzed. PATIENTS & METHODS Fifty-two GC and 23 control samples were included. RESULTS GDF15 and MMP7 proved to be powerful tools for GC(More)
BACKGROUND Detection of isolated tumour cells (ITC) in the blood or minimal deposits in distant organs such as bone marrow (BM) could be important to identify breast cancer patients at high risk of relapse or disease progression. PCR amplification of tissue or tumour selective mRNA is the most powerful analytical tool for detection of this micrometastasis.(More)
We aim to estimate the diagnostic performances of anterior gradient homolog-2 (AGR2) and Leucine-rich repeat-containing-G-protein-coupled receptor 5 (LGR5) in peripheral blood (PB) as mRNA biomarkers in colorectal cancer (CRC) and to explore their prognostic significance. Real-time PCR was used to analyze AGR2 and LGR5 in 54 stages I-IV CRC patients and 19(More)
