The investigators are doing this research to see if they can use small tissue samples or fluid to develop a test that will determine if the tissue samples are related or not related to each other. The test will use the patient's DNA, which is part of their unique genetic material that carries the instructions for the body's development and function. Cancer can result from changes in a person's genetic material that causes cells to divide in an uncontrolled way and, sometimes, to travel to other organs. Currently, researchers and doctors know some of the genetic changes that can cause cancer, but they do not know all of the genetic changes that can cause cancer.
A frequent clinical dilemma in lung cancer care is the management of multifocal lung cancers. The management decision is based on determining if multiple cancers represent true independent primary cancers or related metastasis. This determination is critical to the appropriate staging of the cancers and treatment. Indeed, this distinction represents the difference between aggressive local therapy with either surgery or radiation therapy for primary early stage lesions, or palliative chemotherapy or best supportive care with appropriate symptom management for advanced stage metastatic disease.
No existing pathologic or molecular test is currently capable of making the distinction between multiple independent lung primaries from metastatic disease with accuracy. The recent release of preliminary data from the NLST screening trial, suggesting survival benefit for screening high risk patients with CT scanning, will only increase the number of patients facing these treatment dilemmas. The research team has recently developed a test that allows this distinction with great accuracy. This test allows determination of lineage between two tumors using the identification of large genomic rearrangements using mate pair next generation sequencing (MP). The test has been developed using fresh frozen tissue from resected lung tumors and is currently being validated for a clinical test.
The investigators' goal is to develop the test using cytology and small biopsy specimens.

Neoplasms composed of fatty tissue or connective tissue made up of fat cells in a meshwork of areolar tissue. The concept does not refer to neoplasms located in adipose tissue.
Neoplasms composed of bony tissue, whether normal or of a soft tissue which has become ossified. The concept does not refer to neoplasms located in bones.
Neoplasms composed of fibrous tissue, the ordinary connective tissue of the body, made up largely of yellow or white fibers. The concept does not refer to neoplasms located in fibrous tissue.
Neoplasms composed of connective tissue, including elastic, mucous, reticular, osseous, and cartilaginous tissue. The concept does not refer to neoplasms located in connective tissue.
Neoplasms located in the vasculature system, such as ARTERIES and VEINS. They are differentiated from neoplasms of vascular tissue (NEOPLASMS, VASCULAR TISSUE), such as ANGIOFIBROMA or HEMANGIOMA.
