Frequency of EGFR Mutations in Latinos/Hispanics With Non-Small Cell Lung Cancer

Study Summary

Background: \- Research has shown that the Epidermal Growth Factor Receptor (EGFR) gene is an important target for personalized lung cancer treatment. Individuals who have mutations in the EGFR gene have better responses when treated with certain personalized or targeted therapies compared with conventional chemotherapy. These mutations are more frequent in females with lung cancer who have never smoked, and different ethnic groups have different levels of frequency of the mutations. Researchers are interested in collecting more information on EGFR genetic mutations in Hispanics/Latinos with lung cancer, comparing the frequency of these mutations in males and females and smokers and nonsmokers. This study may lead to better, more personalized care approaches for all individuals with lung cancer. Objectives: \- To study the frequency of Epidermal Growth Factor Receptor mutations in Hispanic/Latino individuals who have been diagnosed with non-small cell lung cancer. Eligibility: \- Hispanic or Latino individuals who have been diagnosed with non-small cell lung cancer and who have lung tissue from a previous biopsy or surgery available for research purposes. Design: * Participants will provide consent for researchers to examine lung tissue collected from a previous biopsy or surgery. * Treatment will not be provided as part of this protocol.
