Colorectal Cancer, ALK, Activating mutations

Expand Collapse Colorectal Cancer  - General Description Colorectal Cancer (CRC) is cancer that initiates in the colon or rectum-the lower part of the digestive system in the body. During digestion, food moves through the stomach and small intestine into the colon. The colon absorbs water and nutrients from food, and stores waste matter (stool) that moves from the colon through the rectum before leaving the body.

Most CRC's and rectal cancers are adenocarcinomas, meaning that they originate in cells that make and release mucus and other fluids. CRC often begins as a growth called a polyp, which may form on the inner wall of the colon or rectum. Over time, some polyps become cancerous. This highlights the importance of colonoscopy screening to find and remove polyps before they become cancerous.

CRC is the fourth most common type of cancer diagnosed in the U.S. Deaths from CRC have decreased with the use of colonoscopies and fecal occult blood tests, which check for blood in the stool. Disparities in survival have been observed between African American and other populations. This may be due to factors such as access to colonoscopy screening, or to other factors not yet identified.

Because of its prevalence, scientists have studied CRC extensively, even creating models of how cancer develops using CRC as an example. There are also families with a very high incidence of CRC occurrence. When these families were studied, certain conditions that create instability in the whole genome were identified that predispose people to CRC. These include what is called the Chromosomal Instability pathway (CIN), as well as MicroSatellite Instability pathway (MSI). These can also occur as spontaneous (uninherited) conditions in some patients. Between 6-10% of CRC's are found to have MSI. Some CRC tumors have been found to have a lot of mutations, or as physicians call it, a "very high mutational load". Some also express a ligand called PD-L1.

These are now recognized features of some CRC's, and immunological treatments may be recommended in these cases. MGH has one of the most extensive Immuno-oncology clinical trials portfolios of any US hospital. Testing for features such as CIN, MSI, a high mutational burden, and the expression of PD-L1 can be conducted at the MGH genetics laboratory, as well as at other large academic centers. Genetic instability such as CIN or MSI lead to the activation of oncogenes such as KRAS, and the inactivation of tumor suppressors such as PTEN, both of which promote tumor growth.

Other genetic alterations in how the DNA in cells is organized have been found to contribute to CRC in families and individuals. These are called epigenetic changes. Normal DNA has methyl groups added in specific regions that regulate gene expression. When the genes that suppress growth-called tumor suppressors-are methylated abnormally, this prevents the production of tumor suppressor proteins important in controlling or stopping cell growth. When tumor suppressor genes are missing, unregulated growth occurs, contributing to the development of cancer. Some tumor suppressor proteins that are frequently inactivated in CRC are APC, TP53, or loss of one arm of chromosome 18 that contains a tumor suppressor.

The study of families with a high prevalence of CRC have lead scientists to discover genetic changes that contribute to the development of CRC in sporadic cases occurring in patients. Mutations in the genes encoding the following proteins have now been associated with subsets of CRC; ALK, AKT, APC, beta-catenin, BRCA1 and BRCA2, BRAF, EGFR, ERBB2 (HER2), ERBB3 (HER3), IDH2, KRAS, MET, NRAS, PI3K, ROS, PTEN, SMO,TP53, TRK 1, 2 and 3, and others that are still being identified. Information on these specific genes is available on this website if you select the gene you want to know more about.

Distinct familial syndromes of CRC such as Lynch syndrome have been studied in patients, leading to the identification of other mechanisms contributing to the development of cancer. Before a cell can divide into two daughter cells, DNA has to be replicated so both daughter cells will have a full complement of chromosomes. DNA replication requires an enzyme called DNA Polymerase. DNA Polymerase occasionally makes errors while it is replicating DNA. Cells therefore have a "proof-reading" process that detects mistakes when they occur during DNA replication. DNA Polymerase mistakes mean that incorrect nucleotides have been incorporated into the DNA, causing mutations. Mistakes in the DNA sequence are repaired in a process called mismatch repair (MMR).
MMR involves a complex of multiple proteins. In Lynch syndrome, one or more of the proteins involved in MMR is mutated, and the mistakes in the DNA do not get corrected. Mutations in MMR proteins are not only found in familial cases of CRC, but also in patients with sporadic (non-inherited) CRC. Defects in MMR also contribute to microsatellite instability (MIS), described above. The accumulation of these mutations can lead to cancer.

The importance of accurately replicating DNA following various types of mistakes or damage is reflected in the multiple pathways cells have for correcting or repairing broken DNA. Actual breaks in the DNA strands can happen due to exposure to radiation or other DNA damaging agents. In the case of the occurrence of breaks in DNA, there are also mechanisms for detecting these breaks. Double strand breaks (DSB's) in the DNA can be repaired via several mechanisms, including Non-Homologous End Joining (NHEJ) or Homologous Repair (HR). Many proteins are involved in DSB repair. Mutations in any of the many proteins involved in either of these repair pathways (see BRCA1 and BRCA2 genes) lead to damaged DNA, which results in DNA that is incorrectly replicated, causing mutations that contribute to the development of cancer. DNA repair machinery in the cell is important in keeping the genome stable and accurate.

Testing for the mutations and genomic conditions that contribute to the development or progression of CRC is available at MGH in the sophisticated CLIA certified genomic testing lab, and in other large Centers and some private testing companies used by physicians. Validated treatments, Immune therpies, as well as clinical trials investigating improved targeted and immunologic therapies are available to patients at MGH.

Expand Collapse ALK  - General Description
CLICK IMAGE FOR MORE INFORMATION
ALK is a gene that provides the code for making a protein called anaplastic lymphoma kinase. This protein belongs to a family of proteins on the cell surface known as receptor tyrosine kinases (RTKs). RTKs are the first link in a chain that sends signals from the outside of a cell to the parts inside the cell that control different cellular processes, such as cell growth, cell division and cell differentiation. Anaplastic lymphoma kinase is believed to play a key role in brain development and helps regulate the proliferation of nerve cells during early stages of development. In cancer, either due to mutation or rearrangements in the ALK gene, its activity is continuously switched on, which in turn drives the cancer process.

At least 16 mutations in the ALK gene have been found in some patients with neuroblastoma, a cancer that develops in the immature nerve cells (neuroblasts) during childhood. In most cases, each mutation alters the structure of the ALK protein in different ways. These mutations result in the signaling pathway being switched on, increasing the proliferation of immature nerve cells and leading to neuroblastoma. Some of these mutations are called somatic because they are acquired during the course of a person's life and are found only in cells that become cancerous (not inherited from a parent). In some people with neuroblastoma, extra copies (gene amplification) of ALK cause too much protein to be made.

Rearrangements in the ALK gene also serve as an important driver of tumor growth. These rearrangements result in the production of a recombinant protein that is comprised of the front end of one protein fused together with the tyrosine kinase domain of ALK. The fusion partner can be any one of a number of genes, depending on the malignancy. For instance, in approximately 70 to 80% of ALK-positive anaplastic large cell lymphomas (ALCL), ALK is paired with the Nucleophosmin (NPM) gene. In lung cancer, ALK's translocation partner is primarily the EML4 gene. ALK rearrangements have also been described in other tumors including inflammatory myofibroblastic tumors, neural tumors, rhabdomyosarcomas and in some subtypes of breast cancer. Another type of rearrangement, an inversion, is found in a few people with non-small cell lung cancer (NSCLC), the most common type of lung cancer.
