MammaPrint is a prognostic and predictive diagnostic test for early stage breast cancer patients that assess the risk that a tumor will metastasize to other parts of the body. It gives a binary result, high-risk or low-risk classification, and helps physicians determine whether or not a patient will benefit from chemotherapy. Women with a low risk result can safely forego chemotherapy without decreasing likelihood of disease free survival. MammaPrint is part of the personalized medicine portfolio marketed by Agendia.
The Cancer Genome Project is part of the cancer, aging, and somatic mutation research based at the Wellcome Trust Sanger Institute in The United Kingdom. It aims to identify sequence variants/mutations critical in the development of human cancers. Like The Cancer Genome Atlas project within the United States, the Cancer Genome Project represents an effort in the War on Cancer to improve cancer diagnosis, treatment, and prevention through a better understanding of the molecular basis of the disease. The Cancer Genome Project was launched by Michael Stratton in 2000, and Peter Campbell is now the group leader of the project. The project works to combine knowledge of the human genome sequence with high throughput mutation detection techniques.
The Cancer Genome Atlas (TCGA) is a project, begun in 2005, to catalogue genetic mutations responsible for cancer, using genome sequencing and bioinformatics. TCGA applies high-throughput genome analysis techniques to improve the ability to diagnose, treat, and prevent cancer through a better understanding of the genetic basis of this disease.
Triple-negative breast cancer is any breast cancer that does not express the genes for estrogen receptor (ER), progesterone receptor (PR) and HER2/neu. This makes it more difficult to treat since most hormone therapies target one of the three receptors, so triple-negative cancers often require combination therapies. Triple negative is sometimes used as a surrogate term for basal-like; however, more detailed classification may provide better guidance for treatment and better estimates for prognosis.
The basal-like carcinoma is a recently proposed subtype of breast cancer defined by its gene expression and protein expression profile.
The International Cancer Genome Consortium (ICGC) is a voluntary scientific organization that provides a forum for collaboration among the world's leading cancer and genomic researchers. The ICGC was launched in 2008 to coordinate large-scale cancer genome studies in tumours from 50 cancer types and/or subtypes that are of main importance across the globe.
Breast cancer classification divides breast cancer into categories according to different schemes criteria and serving a different purpose. The major categories are the histopathological type, the grade of the tumor, the stage of the tumor, and the expression of proteins and genes. As knowledge of cancer cell biology develops these classifications are updated.

Cancer is a category of disease characterized by uncontrolled cell growth and proliferation. For cancer to develop, genes regulating cell growth and differentiation must be altered; these mutations are then maintained through subsequent cell divisions and are thus present in all cancerous cells. 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.
Cancer genome sequencing is the whole genome sequencing of a single, homogeneous or heterogeneous group of cancer cells. It is a biochemical laboratory method for the characterization and identification of the DNA or RNA sequences of cancer cell(s).
The term radiogenomics is used in two contexts: either to refer to the study of genetic variation associated with response to radiation or to refer to the correlation between cancer imaging features and gene expression.
Targeted molecular therapy for neuroblastoma involves treatment aimed at molecular targets that have a unique expression in this form of cancer. Neuroblastoma, the second most common pediatric malignant tumor, often involves treatment through intensive chemotherapy. A number of molecular targets have been identified for the treatment of high-risk forms of this disease. Aiming treatment in this way provides a more selective way to treat the disease, decreasing the risk for toxicities that are associated with the typical treatment regimen. Treatment using these targets can supplement or replace some of the intensive chemotherapy that is used for neuroblastoma. These molecular targets of this disease include GD2, ALK, and CD133. GD2 is a target of immunotherapy, and is the most fully developed of these treatment methods, but is also associated with toxicities. ALK has more recently been discovered, and drugs in development for this target are proving to be successful in neuroblastoma treatment. The role of CD133 in neuroblastoma has also been more recently discovered and is an effective target for treatment of this disease.
Molecular diagnostics is a collection of techniques used to analyse biological markers in the genome and proteome—the individual's genetic code and how their cells express their genes as proteins—by applying molecular biology to medical testing. The technique is used to diagnose and monitor disease, detect risk, and decide which therapies will work best for individual patients.

Personalized onco-genomics is a growing area of interest in the field of oncology and genomics that is focused on utilizing whole genome analysis to make rational clinical treatment decisions for each individual patient. The idea for this program was devised at Canada's Michael Smith Genome Sciences Centre and is currently being led by Dr. Marco Marra and Dr. Janessa Laskin. Genome instability has been identified as one of the underlying hallmarks of cancer. The genetic diversity of cancer cells promotes multiple other cancer hallmark functions that help them survive in their microenvironment and eventually metastasise. The pronounced genomic heterogeneity of tumours has led researchers to develop an approach that assesses each individual's cancer to identify targeted therapies that can halt cancer growth. Identification of these “drivers” and corresponding medications used to possibly halt these pathways are becoming increasingly important in the treatment of cancer.
