Résumé :

Abstract Context.—The traditional triple test for breast cancer diagnosis is physical examination, mammography, and aspiration cytology. However, the accuracy of mammography on young women with nonatrophied breasts is poor compared with that for women older than 50 years, and additional methods for diagnosis of breast cancer are needed. Objective.—To investigate whether carcinoembryonic antigen (CEA), CA 15-3, and CA 125 concentrations in breast aspiration fluid are useful as breast cancer biochemical markers and whether APC and cyclin D2 gene promoter hypermethylation could be regarded as a b

Résumé :

Cancer cells display heterogeneous genetic characteristics, depending on the tumor dynamic microenvironment. Abnormal tumor vasculature and poor tissue oxygenation generate a fraction of hypoxic tumor cells that have selective advantages in metastasis and invasion and often resist chemo- and radiation therapies. The genetic alterations acquired by tumors modify their biochemical pathways, which results in abnormal tumor metabolism. An elevation in glycolysis known as the “Warburg effect” and changes in lipid synthesis and oxidation occur. Magnetic resonance spectroscopy (MRS) has been used to

Objective: The liver is the second most common site of distant metastasis from breast cancer that is usually associated with poor prognosis and low quality of life in breast cancer patients. Therefore, the primary diagnosis of liver metastatic lesions in breast cancer patients is very important. In this study, the ability of biochemical markers CA153, CEA, and ALP to be used for prognostic liver metastasis in women with breast cancer was investigated.

Résumé :

The skeleton is the main site affected by metastases and breast cancer is the most frequent tumor to invade bone. The assessment of bone metastases is difficult and biochemical markers of bone formation (BFMs) could be a promising alternative. Although the essential role of osteoblasts in the metastatic process of bone destruction is now well established, little attention has been paid to BFMs. We conducted a Medline search for studies about BFMs in breast cancer. Our review allows us to conclude that BFMs have high specificity but low sensitivity for the diagnosis of bone metastases. The avai

AbstractBreast cancer is one of the most frequently diagnosed cancers among women in the western world. Due to the aggressive behaviour of some specific types and the possibility of an early diagnosis, breast cancer has been constantly studied. Tumour size, histological type, cellular and nuclear characteristics, mitotic index, vascular invasion, hormonal receptors and axillary lymph node status are biomarkers routinely used. However, these parameters are not enough to predict the course of this disease. Molecular biology advances have made it possible to find new markers, which have already b

Résumé :

Pancreatic cancer (PC) is the fourth leading cause of cancer death, with a median survival of 6 months and a dismal 5-year survival rate of 35%, a figure which has remained relatively unchanged over the past 25 years. PC is one of the most difficult diseases to treat due to late initial diagnosis and to resistance to the usual treatments. The presence of occult or clinical metastases at the time of diagnosis, together with the lack of effective chemotherapies, contributes to the high mortality in patients with PC. Its lethal nature stems from its propensity to disseminate rapidly to the lymph

Serum levels of breast carcinoma antigen (CA 15.3) and urinary calcium excretion (UCa) were determined in 73 patients with breast cancer: 36 without bone metastases (stage I-IV) and 37 with bone metastases. The patients in the latter group were further investigated at 2,4 and 6 months from the start of treatment. Both markers showed significant elevations in the group with bone metastases (CA 15.3: P = 1.0×10–6, UCa: P = 8.6×10–9). The bone metastasis index (BMI), which represents the combination of the markers, had better diagnostic efficacy (90%) than CA 15.3 alone (84%) or UCa alone (82%).

Résumé :

The prevalence and mortality of breast cancer is increasing in Asian countries, including India. With advances in medical technology leading to better detection and characterization of the disease, it has been possible to classify breast cancer into various subtypes using markers, which helps predict the risk of distant recurrence, response to therapy, and prognosis using a combination of molecular and clinical parameters. Breast cancer and its therapy, mainly surgery, systemic therapy (anticancer chemotherapy, hormonal therapy, targeted therapy, and immunotherapy), and radiation therapy, are

Résumé :

Abstract More fundamental understanding of cell growth regulation will provide novel approaches for detecting, preventing, and treating different cancers. Activation of protooncogenes or loss of tumor-suppressor genes can have both prognostic and therapeutic importance. In epithelial ovarian cancer, poor prognosis is associated with continued expression or overexpression of tyrosine kinase growth factor receptors p170EGFR, p165fms, and p185erbB-2. Over-expression of erbB-2 (HER-2/neu) by breast and ovarian cancers already permits effective targeting of antibodies and immunotoxins. Ultimately,

Résumé :

The ability to identify a specific cancer using minimally invasive biopsy holds great promise for improving the diagnosis, treatment selection, and prediction of prognosis in cancer. Using whole-genome methylation data from The Cancer Genome Atlas (TCGA) and machine learning methods, we evaluated the utility of DNA methylation for differentiating tumor tissue and normal tissue for four common cancers (breast, colon, liver, and lung). We identified cancer markers in a training cohort of 1,619 tumor samples and 173 matched adjacent normal tissue samples. We replicated our findings in a separate

Résumé :

Aberrant DNA hypermethylation at gene promoters is a frequent event in human breast cancer. Recent genome-wide studies have identified hundreds of genes that exhibit differential methylation between breast cancer cells and normal breast tissue. Due to the tumor-specific nature of DNA hypermethylation events, their use as tumor biomarkers is usually not hampered by analytical signals from normal cells, which is a general problem for existing protein tumor markers used for clinical assessment of breast cancer. There is accumulating evidence that DNA-methylation changes in breast cancer patients

Abstract Introduction Studies of triple-negative breast cancer have recently been extending the inclusion criteria and incorporating additional molecular markers into the selection criteria, opening up scope for targeted therapies. The screening phases required for studies of this type are often prolonged, since the process of determining the molecular subtype and carrying out additional biomarker assessment is time-consuming. Parameters such as germline genotypes capable of predicting the molecular subtype before it becomes available from pathology might be helpful for treatment planning and

Background: Performing a prostate biopsy is the most robust and reliable way to diagnose prostate cancer (PCa), and to determine the disease grading. As little to no biochemical markers for prostate tissue exist, we explored the possibilities of tissue N-glycosylation and near-infrared spectroscopy (NIR) in PCa diagnosis. Methods: Tissue specimens from 100 patients (benign prostate hyperplasia (BPH), n = 50; and PCa, n = 50) were obtained. The fresh-frozen tissue was dispersed and a tissue N-glycosylation profile was determined. Consequently, the formalin-fixed paraffin-embedded slides were an

Atypical parathyroid adenomas represent a group of intermediate form of parathyroid neoplasms of uncertain malignant potential which show some atypical histological features that represent a challenge for the differential diagnosis with parathyroid carcinomas. They may occur as sporadic or as a part of hereditary syndromes. The molecular signature of these neoplasms is still unknown and the germline CDC73 mutations appears to be the most common anomaly in this setting suggesting that these cases might represent variants of the hyperparathyroidism-jaw tumor syndrome.

Breast cancer (BC) is not a typical manifestation of Lynch syndrome. The existence and extent of excessive breast cancer risk in carriers of pathogenic mutations in the Lynch syndrome-associated genes (MLH1, MSH2, MSH6, PMS2) remains an open question. In addition, it is known that some of the breast neoplasms in patients with this syndrome are causally linked to the hereditary mutation, and some arise completely independently of the hereditary defect in the gene of the DNA mismatch repair system.
