Gene expression profiling is a technique used in molecular biology to query the expression of thousands of genes simultaneously. In the context of cancer, gene expression profiling has been used to more accurately classify tumors. The information derived from gene expression profiling often helps in predicting the patient's clinical outcome.
Patients are typically offered testing if they have either a personal or family history of cancer that meets certain criteria, Zakalik adds. Those criteria have broadened over the last few years ...
The cancer stem cell model asserts that within a population of tumour cells, there is only a small subset of cells that are tumourigenic (able to form tumours). These cells are termed cancer stem cells (CSCs), and are marked by the ability to both self-renew and differentiate into non-tumourigenic progeny. The CSC model posits that the ...
Tumor markers can be molecules that are produced in higher amounts by cancer cells than normal cells, but can also be produced by other cells from a reaction with the cancer. [2] The markers can't be used to give patients a diagnosis but can be compared with the result of other tests like biopsy or imaging. [2]
The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...
Mismatch repair cancer syndrome (MMRCS) is a cancer syndrome associated with biallelic DNA mismatch repair mutations. [1] It is also known as Turcot syndrome (after Jacques Turcot, who described the condition in 1959) and by several other names. [1] In MMRCS, neoplasia typically occurs in both the gut and the central nervous system (CNS). [1]
In a 2020 study of 55,000 veterans with lung cancer, participating in a mental health treatment program was associated with 20%-25% lower risk of dying from cancer. Gaps in accessing mental health ...
