However, the researchers determined that since most health care demands of heart failure patients occur early after diagnosis and most cancers were diagnosed after 1.5 years, this detection bias was not a major reason for more
instances of cancer diagnosis in heart failure patients.
To cite a few
instances, polymerase chain reaction (PCR), a molecular method developed over three decades ago, has been widely applied in disease
diagnosis, disease mechanism deciphering, and prognosis prediction; the elucidation
of tyrosine kinase activity in
cancer cells has led to the development
of novel drugs for
cancer treatment; and the identification
of proteins and genetic molecules by molecular methods as biomarkers for disease
diagnosis and prognosis has been drawing great interest.
