Peptidomics for Cancer Diagnosis: Present and Future

Abstract
Analysis of peptides in biological fluids by mass spectrometry holds promise of providing diagnostic and prognostic information for cancer and other diseases. Before this technology is used clinically, it is important to understand its advantages and limitations. These are summarized, along with proposals, on how to proceed in the future.
