Project description:This study explored methylation, clinical, and other molecular alterations longitudinally over the course of smoking cessatio in healthy women aged 30 to 60. Here, we present methylation data from three matched sample types - buccal, cervical, and blood - longitudinally over the course of six months (baseline, month 2, month 4, and month 6).
Project description:RATIONALE: Continued smoking after a cancer diagnosis has important health consequences beyond the risks associated with smoking in the general population. Smoking reduces the efficacy of cancer treatments including surgery, radiation and chemotherapy. Despite the negative consequences, it is estimated that between 15-75% of patients with cancer continue to smoke after their cancer diagnosis. Lung, breast, prostate, colorectal, bladder, head & neck, and cervical cancer patients were chosen because there is evidence of potential clinical benefit associated with quitting smoking in all of these populations and they represent a mix of both smoking and non-smoking related cancers.
