Abstract

This chapter introduces genomics and proteomics as the new generic tools for diagnosis of pituitary adenomas. The development of tumor-associated serum protein biomarkers over the past few decades has not been much effective for diagnosing primary neoplasia. There is a considerable pressure to discover new disease-related biomarkers. These markers are quantitative measures of biological effects that provide informative links between the mechanism of action and clinical effectiveness. They can provide new insights into a drug's mechanism of action, metabolism, efficacy, and safety, and into disease mechanisms and disease course. Protein biomarkers show a high potential of conversion into paraclinical diagnostic tests. Genomic analysis is one of the most intensively exploited “instrument” in biomarker discovery. Large-scale sequencing of candidate genes provides new biomarkers for tumor diagnosis and prognosis. Somatic DNA sequence analysis has expanded to genome-wide high-performance DNA sequencing leading to whole genome analysis of DNA sequence variations in tumors.
