Possible correlation to increased risk for African-Americans
AURORA, COLO – A recent study published in the October 2009 issue of the Journal of Thoracic Oncology determined that variations of specific genetic markers identified in previous research, or SNPs, may indicate a greater lung cancer risk in African Americans than in whites. The genes CHRNA3 and CHRNA5 may contribute to lung cancer risk due directly or through their association with nicotine dependence. Although their presence is less frequent in African Americans, the risk for lung cancer may be greater when present.
Researchers from the Karmanos Cancer Institute in Detroit, MI and the MD Anderson Cancer Center in Houston, TX evaluated data on 1,508 non-small cell lung cancer(NSCLC) patients (38 percent of which were African American) selected from the Detroit SEER Cancer registry and 1,314 corresponding control patients matched based on age, gender and race. The three case-controlled studies examined family history of lung cancer, smoking history, and age. Using unconditional logistical regression, a type of statistical analysis, researchers identified associations between SNPs and lung cancer risk while controlling for age, sex and smoking behavior.
Journal of Thoracic Oncology (JTO) – (journals.lww.com/jto)
The JTO is rapidly becoming a prized resource for medical specialists and scientists who focus on the detection, prevention, diagnosis and treatment of lung cancer. The JTO is the official monthly journal of the International Association for the Study of Lung Cancer (IASLC.org) and emphasizes a multidisciplinary approach, including original research (clinical trials and translational or basic research), reviews and opinion pieces.
