Lung Cancer, BRAF

Expand Collapse Lung Cancer  - General Description This year about 226,000 people in the U.S. will be told by a doctor that they have lung cancer. However, about 390,000 Americans remain alive today after having been diagnosed with this malignancy. Lung cancer includes tumors that begin in tissues lining air passages inside the lungs and bronchi. The bronchi are the 2 branches of the windpipe (trachea) that lead to the lungs. Based on how the cells look under a microscope, lung cancers are divided into 2 main types: small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). NSCLC accounts for 85% of these cases.

The main subtypes of NSCLC are squamous cell carcinoma (cancer beginning in thin, flat scaly-looking cells), adenocarcinoma (cancer beginning in cells that make mucus and other substances) and large cell carcinoma (cancer beginning in several types of large cells). The 2 main types of SCLC are small cell carcinoma (oat cell cancer) and combined small cell carcinoma.

Lung cancer (and other tumors) can spread (metastasize) from the place where it started (the primary tumor) in 3 ways. First, it can invade the normal tissue surrounding it. Second, cancer cells can enter the lymph system and travel through lymph vessels to distant parts of the body. Third, the cancer cells can get into the bloodstream and go to other places in the body. In these distant places, the cancer cells cause secondary tumors to grow. The main sites to which lung cancer spreads are the adrenal gland, liver and lungs.

To find out whether the cancer has entered the lymph system, a surgeon removes all or part of a node near the primary tumor and a pathologist looks at it through a microscope to see if cancer cells are present. Several kinds of imaging also can be performed to determine if the cancer has spread. These include MRI, bone scans and endoscopic ultrasound (EUS).

The FDA has approved several targeted therapies to treat patients with NSCLC. These include bevacizumab (Avastin), cetuximab (Erbitux), erlotinib (Tarceva), gefitnib (Iressa) and crizotinib (Xalkori). So far there are no FDA-approved targeted therapies for SCLC.

Despite significant improvements in the treatment of lung cancers, novel therapies and treatment strategies are needed.

Estimated new cases and deaths from lung cancer (non-small cell and small cell combined) in the United States in 2012:

New cases: 226,160
Deaths: 160,340

Lung cancer is the leading cause of cancer-related mortality in the United States. The 5-year relative survival rate from 1995 to 2001 for patients with lung cancer was 15.7%. The 5-year relative survival rate varies markedly depending on the stage at diagnosis, from 49% to 16% to 2% for patients with local, regional and distant stage disease, respectively.

NSCLC arises from the epithelial cells of the lung, from the central bronchi to the terminal alveoli. The histological type of NSCLC correlates with the site of origin, reflecting the variation in respiratory tract epithelium from the bronchi to the alveoli. Squamous cell carcinoma usually starts near a central bronchus while adenocarcinoma usually originates in peripheral lung tissue.

Tobacco smoking is the strongest risk factor for developing lung cancer, though it should be noted that the majority of patients diagnosed with lung cancer quit smoking years prior to diagnosis or were never-smokers (up to 15% of cases).

The identification of driver oncogene mutations in lung cancer has led to the development of targeted therapy that has vastly broadened treatment options and improved outcomes for subsets of patients with metastatic disease. It is now common practice to determine the genotype of a NSCLC patient early in the course of their diagnosis, to ensure that all possible treatment options are considered.

Expand Collapse BRAF  - General Description
CLICK IMAGE FOR MORE INFORMATION
The BRAF gene encodes a serine/threonine kinase that activates the growth-promoting MAP kinase signaling cascade. BRAF is commonly activated by somatic point mutations in human cancers, most frequently by mutations located within the kinase domain at amino acid positions G466, G469, L597 and V600.

In regards to treatment, the Food and Drug Administration (FDA) approved the BRAF inhibitor, vemurafenib, for the treatment of unresectable or metastatic melanoma patients harboring specifically the BRAF V600E mutation, as detected by an FDA-approved test. In addition, there are a growing number of targeted agents that are being evaluated for the treatment of various BRAF-mutant advanced cancers, including other RAF kinase inhibitors and/or MEK inhibitors. Recently, the combination of the BRAF inhibitor dabrafenib with the MEK inhibitor trametinib was approved by FDA for the treatment of patients with BRAF V600E or V600K mutations.

Tumor mutation profiling performed clinically at the MGH Cancer Center has identified the highest incidence of BRAF mutations in thyroid cancer (30-40%), melanoma (20-30%) and colon cancer (10-15%).

Expand Collapse BRAF  in Lung Cancer
Genetic alterations in the gene encoding BRAF have been found in lung cancers. These mutations in the gene result in an abnormal protein, one that cannot be regulated normally. Mutated BRAF is constantly in an activated state, sending cells signals to grow and divide, contributing to the development of cancer.
