This study will examine patients with non-small cell lung cancer metastasis, that is, the distant spreading of tumors to the brain, and compare them with patients without brain metastasis. The molecular and genetic events that permit tumor metastasis are not well understood. There is intense investigation going on into the process in which tumor cells escape the primary local tumor, spread to distant places in the body, and find and create conditions that promote growth in those tissues. Metastasis of tumors such as lung cancer to the brain is a common problem. Tumor cells will be analyzed with the use of microarrays. A microarray is a tool for analyzing gene expression, consisting of a small membrane or glass slide containing samples of many genes arranged in a regular pattern. The goal is to identify a potential molecular signature. It is hoped that there will be discovery of why some patients are more likely than others to develop a brain metastasis, which can have a major negative effect on the quality of life and survival.

Patients 18 years of age with known or evidence by radiology of a non-small cell lung cancer metastatic to the brain, either squamous cells or adenocarcinoma tumors, or those who have had a removal of a brain tumor for diagnosis or treatment may be eligible for this study.

Participants will undergo the following procedures and tests:

* Craniotomy, that is, surgical opening of the skull, and removal of the brain tumor.
* Blood specimens taken from a central vein or artery before the operation, throughout as needed, and for several days afterward, to measure blood chemistries, blood count, and so forth.
* Physical examination and imaging of the central nervous system before and after surgery.
* Urine or serum, or both, pregnancy test of women of childbearing potential.

Patients will also undergo blood tests at 3-month intervals after surgery for up to 5 years. The purpose is to determine if there are tumor cells in the blood, which may explain how they reached the brain.

Introduction: The molecular and genetic events that permit tumor metastasis are not well understood. The process whereby tumor cells escape the primary, local tumor, spread to distant sites in the body and find and create conditions conducive to growth in these disparate tissues remains an area of intense investigation. Metastasis of epithelial tumors, such as lung cancer, to the brain is a common problem, with significant consequences with respect to neurological dysfunction and shortening of survival.

Objective: To study two subset of patients with non small cell lung cancer (NSCLC) metastatic to the brain, to identify genes and proteins that facilitate metastasis.

Study Population: 78 patients with NSCLC (n=39 squamous cell (SQ), and n=39 adenocarcinoma (AC) tumors) metastatic to the brain to compare with published microarray studies of non-metastatic NSCLC patients with these tumor types as well as with one another to help explain the differential trend toward metastasis in some patients with NSCLC and not others, as well as the differential trend to brain metastasis in the AC subtype.

Anticipated Risks and Benefits: Less than minimal risk to the patients to sample tissue already removed from the brain as part of medically-necessary surgery and to sample blood. No direct benefit to the patient is expected.

Outcome Estimate and Potential Meaning for the Field: That this very detailed investigation of the genes and proteins expressed differentially between the non-metastatic and metastatic NSCLCs, as well as between SQ and AC subtypes will identify new or previously-unsuspected targets for new therapies to either prevent the development of brain metastasis or to treat brain metastases more effectively.

This study will examine two subsets of patients with breast cancer metastasis, that is, spreading, to the brain. It will identify genes and proteins that promote metastasis, particularly in women who are found to over-express (have more than other people do) the human epidermal growth factor receptor, ErbB2, also known as HER-2. The molecular and genetic events that permit tumor metastasis are not well understood. There is intense investigation going on into the process in which tumor cells escape the primary local tumor, spread to distant places in the body, and find and create conditions that promote growth in those tissues.

Objective: To study two subset of patients with breast cancer metastatic to the brain, to identify genes and proteins that facilitate metastasis, particularly in women who over-express the growth factor receptor HER2, in which an increased risk of brain metastasis has recently been identified.

Study Population: 78 patients with breast cancer metastatic to the brain (39 women whose tumors are HER2-(-) and 39 women whose tumors are HER2-(+)) to compare with published microarray studies of non-metastatic breast cancer patients with these tumor types as well as with one another to help explain the differential trend toward metastasis in patients treated with Herceptin, a new therapy directed at HER-2 over-expressing tumors.

Anticipated Risks and Benefits: Less than minimal risk to the patients to sample tissue already removed from the brain as part of medically-necessary surgery and to sample blood. No direct benefit to the patient is expected.

Outcome Estimate and Potential Meaning for the Field: That this very detailed investigation of the genes and proteins expressed differentially between the non-metastatic and metastatic breast cancers, as well as between HER2-(-) and HER2-(+) subtypes will identify new or previously-unsuspected targets for new therapies to either prevent the development of brain metastasis or to treat these brain metastases more effectively.
