Lung cancer is one of the diseases responsible for a large number of cancer related death cases worldwide. The recommended standard for screening and early detection of lung cancer is the low dose computed tomography. However, many patients diagnosed die within one year, which makes it essential to find alternative approaches for screening and early detection of lung cancer. We present computat...
Signal detection and Bayesian inferential tools were applied to salivary biomarkers to improve screening accuracy and efficiency in detecting oral squamous cell carcinoma (OSCC). Potential cancer biomarkers are identified by significant differences in assay concentrations, receiver operating characteristic areas under the curve (AUCs), sensitivity, and specificity. However, the end goal is to r...
abstract breast cancer is one of the major health problems of the eastern world. regardless of the survival rate improvement with progression in screening and adjuvant systemic therapies, still one – third of the patients with primary breast cancer have recurrence of micro metastasis after 10 years. it is important to discover a reliable biomarker for detection of breast cancer. the underlying...
Recent developments in such areas of research as geneexpression microarrays, proteomics, and immunology offer new approaches to cancer screening (1). The surge in research to develop cancer-screening biomarkers prompted the establishment of the Early Detection Research Network (EDRN) by the National Cancer Institute (2). The purpose of the EDRN is to coordinate research among biomarker-developm...
Controversy surrounds the use of PSA as a biomarker for prostate cancer detection, leaving an unmet need for a novel biomarker in this setting; urinary EN2 may identify individuals with clinically relevant prostate cancer. Male BRCA1 and BRCA2 mutation carriers are at increased risk of clinically significant prostate cancer and may benefit from screening. Urine samples from 413 BRCA1 and BRCA2 ...
BACKGROUND Biomarker tests are increasingly being offered by laboratories and clinicians as self-pay health services to screen asymptomatic individuals; however, sufficient evidence may not be available to support this practice. We investigated the benefit-harm tradeoffs associated with 11 biomarkers currently offered in Germany as self-pay tests to screen for cancer. METHODS We systematicall...
Current anticancer therapy may be one of the most important exogenous sources of exposure to genotoxic agents in US, Japan, and Europe, where approximately 40-55 percent of the population is diagnosed with cancer at a certain point in their life. This review focuses on recent efforts to integrate a novel biomarker, gamma-H2AX, into anticancer drug screening to classify the mode of action (MoA) ...
BACKGROUND New cancer biomarkers are being discovered at a rapid pace; however, these tests vary in their predictive performance characteristics, and it is unclear how best to use them. METHODS We investigated 2-stage biomarker-based screening strategies in the context of prostate cancer using a partially observable Markov model to simulate patients' progression through prostate cancer states...
Research methods for biomarker evaluation lag behind those for evaluating therapeutic treatments. Although a phased approach to development of biomarkers exists and guidelines are available for reporting study results, a coherent and comprehensive set of guidelines for study design has not been delineated. We describe a nested case-control study design that involves prospective collection of sp...
