Diagnostic accuracy of computed tomographic colonography for the detection of advanced neoplasia in individuals at increased risk of colorectal cance…
2009
CONTEXT: Computed tomographic (CT) colonography has been recognized as an alternative for colorectal cancer (CRC) screening in average-risk individuals, but less information is available on its performance in individuals at increased risk of CRC. OBJECTIVE: To assess the accuracy of CT colonography in detecting advanced colorectal neoplasia in asymptomatic individuals at increased risk of CRC using unblinded colonoscopy as the reference standard. DESIGN, SETTING, AND PARTICIPANTS: This was a multicenter, cross-sectional study. Individuals at increased risk of CRC due to either family history of advanced neoplasia in first-degree relatives, personal history of colorectal adenomas, or positiv…
Triple-negative breast cancer: Molecular features, pathogenesis, treatment and current lines of research
2010
Breast cancer is a heterogeneous disease with different morphologies, molecular profiles, clinical behaviour and response to therapy. The triple negative is a particular type of breast cancer defined by absence of oestrogen and progesterone receptor expression as well as absence of ERBB2 amplification. It is characterized by its biological aggressiveness, worse prognosis and lack of a therapeutic target in contrast with hormonal receptor positive and ERBB2+ breast cancers. Given these characteristics, triple-negative breast cancer is a challenge in today's clinical practice. A new breast cancer classification emerged recently in the scientific scene based in gene expression profiles. The ne…
Prognostic scores for hepatocellular carcinoma: none is the winner
2009
Cancer classification and indication of treatment are critical steps in the management of patients with hepatocellular carcinoma (HCC). The prediction of outcome is relevant to provide adequate information to patients and relatives, both at the time of treatment selection and after the application of therapy. Tumour staging describes the extent of an individual's tumour burden in the original primary organ and spread throughout the body, and other cofactors such as age or histological grade are only seldom considered. This is common to all malignancies and diseases. However, whereas for most neoplasms prognosis and treatment are largely dictated by tumour stage at the time of diagnosis, the…
