OBJECTIVE Invasive cervical cancer (ICC) is one of the most common malignant diseases among women, representing almost 10% of all the cancers in the female population. The aim of this study was to explore the association of the CCR2-64I polymorphism with the risk of developing invasive cervical cancer (ICC) from squamous intraepithelial lesions (SILs). (More)
Leptin hormone and receptor have been associated to cancer development and were identified in lung tissue. In this study, a functional polymorphism in the 5' flanking region of the leptin gene (LEP -2548 G/A) was found to increase susceptibility for non-small cell lung cancer [odds ratio (OR), 1.97; 95% confidence interval (CI), 1.13-3.43]. Age-adjusted(More)
PURPOSE The purpose of our study was to determine whether the amounts of circulating DNA (cDNA) could discriminate between NSCLC patients and healthy individuals and assess its value as a prognostic marker of this disease. METHODS We conducted a study of 309 individuals and the cDNA levels were assessed through real-time PCR methodology. RESULTS We(More)
AIM To determine whether the amounts of circulating DNA could discriminate between breast cancer patients and healthy individuals by using real-time PCR quantification methodology. METHODS Our standard protocol for quantification of cell-free plasma DNA involved 175 consecutive patients with breast cancer and 80 healthy controls. RESULTS We found(More)
Worldwide, approximately 1.3 billion individuals are current smokers, and smoking is the second major cause of death. Currently, lung cancer is the most common type of cancer in Europe, and the third in the U.S. Until now, cytotoxic chemotherapy has had a limited impact on survival in metastatic non-small cell lung cancer (NSCLC). The central role of(More)
Lung cancer is the leading cause of death by cancer in the world, originating about 17.5% of total deaths from cancer (1.18 million). Inflammation plays an important role in the pathogenesis of lung cancer. IL-4 is an anti-inflammatory cytokine, which reduces the production of proinflammatory cytokines by monocytes and with direct antiproliferative effects(More)
Non-small cell lung cancer (NSCLC) is the most common cancer and the leading cause of death from cancer worldwide. Antiangiogenic strategies directed towards tumor stroma are becoming gold standard in NSCLC treatment and researchers have been searching for biomarkers to identify patients for whom therapy with antiangiogenic inhibitors may be most beneficial(More)
Lung cancer was found to be the most commonly diagnosed cancer, as well as the primary cause of cancer-related mortality for males worldwide and the second leading cause of cancer-related deaths for women. Cytokines are fundamental for several biological processes-associated malignant tumors. The IL-6 is a cytokine involved in the regulation of cellular(More)
Testosterone exposure has been implicated in prostate carcinogenesis, and genes that alter its metabolism, such as CYP3A4, have been associated with prostate cancer susceptibility. The aim of our study was to assess the relationship between the CYP3A4 *1B polymorphism and its possible role in the development of prostate cancer. DNA samples obtained from the(More)
Invasive squamous cell carcinomas of the cervix arise from earlier, reversible precursor lesions called low- and high-grade squamous intraepithelial lesions (LSIL and HSIL, respectively). The aim of our study was to analyse the influence of the CCR2-64I polymorphism in the development of SIL due to its preponderant role in the cervical carcinogenesis and in(More)
