Biomarkers: the next generation

Metrics details. Randomized controlled trials RCTs for prevention of AD dementia often use clinical endpoints that take years to manifest e. Blood biomarkers represent a clinically applicable alternative surrogate endpoint for RCTs that would be both cost-effective and minimally invasive, but little is known about their value as surrogate endpoints for treatment responses in the prevention of AD dementia.

Many people naturally assume that the claims made for foods and nutritional supplements have the same degree of scientific grounding as those for medication, but that is not always the case. The IOM recommends that the FDA adopt a consistent scientific framework for biomarker evaluation in order to achieve a rigorous and transparent process.

Alastair K. Denniston, Pearse A. Keane, Sunil K. Purpose : Uveitis is a major cause of sight loss across the world. Methods : This is a narrative review based on searches of the current world literature using terms related to quantitative imaging techniques in uveitis, supplemented by clinical trial registry data, and expert knowledge of surrogate endpoints and outcome measures in ophthalmology. Results : Current measures of disease activity are largely based on subjective clinical estimation, and are relatively insensitive, with poor discrimination and reliability. The development of quantitative imaging in uveitis is most established in the use of optical coherence tomographic OCT measurement of central macular thickness CMT to measure severity of macular edema ME.

The identification and validation of putative surrogate endpoints in oncology is a great challenge to medical investigators, statisticians, and regulators. A putative surrogate endpoint must be validated at both individual-level and trial-level before it can be used to replace the clinical endpoint in a future clinical trial. Recently, meta-analytic methods for evaluating potential surrogates have become widely accepted in cancer clinical trials. In this review, after addressing multiple complications and general issues surrounding surrogate endpoints, we review various proposed and adopted meta-analytic methodologies pertaining to the application of these methods to oncology clinical trials with different tumor types. In oncology, several applications have successfully identified useful surrogates. For example, disease-free survival and progression-free survival have been validated through meta-analyses as acceptable surrogates for overall survival in adjuvant colon cancer and advanced colorectal cancer, respectively.

Imaging Tumor Response to Therapy pp Cite as. Despite several decades of intensive clinical and biological research and significant progress in primary prevention, screening, diagnosis, prognosis, and treatment, cancer is still the second most common cause of death in developed countries, accounting for about one-fourth of total deaths [1]. Accordingly, an improvement in the prognosis of cancer patients is a powerful stimulus for researchers, regulatory agencies, and the health care industry and, of course, a high priority for patients and society.

 Но… Послышался щелчок положенной на рычаг трубки. Беккер беззвучно выругался и повесил трубку. Третья попытка провалилась. Он помнил, что сказал Клушар: немец нанял девушку на весь уик-энд. Беккер вышел из телефонной будки на перекрестке калле Саладо и авениды Асунсьон. Несмотря на интенсивное движение, воздух был наполнен сладким ароматом севильских апельсиновых деревьев. Спустились сумерки - самое романтическое время суток.
