Noninvasive Quantitative Imaging–based Biomarkers and Lung Cancer Screening

Potential biomarkers for lung cancer screening.

Notwithstanding the encouraging results of the National Lung Screening Trial (NLST) the scientific community still debates on the cost-benefit profile of low dose computed tomography (LDCT) lung cancer screening. Several major concerns regard how to identify subjects at high risk of developing lung cancer, the optimal diagnostic algorithm, the management of lung nodules and the high false posit...

Biomarkers in lung cancer.

Here we review the role of tissutal and circulating biomarkers in the management of lung cancer. In the past they were considerate quite ineffective tools as regards prognosis and prediction of treatment activity, nowadays instead, they are becoming a crucial key point as potential predictive issues in driving therapy, with possibly prognostic values as well.

Biomarkers in Colorectal Cancer Screening

Colorectal cancer is the second most frequent cause of death by cancer. Current gold standard screening tools are invasive, expensive, and require a lot of preparation, which result in decreased patient compliance. Screening modalities that are less invasive, have high sensitivity and specificity, inexpensive, and more accepted by the general population than the current gold standard screening ...

Biomarkers in Cervical Cancer Screening

In industrialized countries, population wide cytological screening programs using the Pap test have led to a substantial reduction of the incidence of cervical cancer. Despite this evident success, screening programs that rely on Pap-stained cytological samples have several limitations. First, a number of equivocal or mildly abnormal test results require costly work up by either repeated retest...
