P2.06-007 - Demographic Characteristics of Lung Cancer and Association with Wood Smoke in Mexican Population (ID 9638)
09:30 - 09:30 | Author(s): V. Imaz-Olguín
- Abstract
Background:
Retrospective, longitudinal, unicentric and cohort study that analyzes the demographic characteristics of the Mexican population with lung cancer and its association with wood smoke exposure.
Method:
The study had 123 patients pathologically diagnosed with lung cancer between January 2013 to January 2014 at the National Institute of Respiratory Diseases. The primary endpoint was the histological type of lung cancer and the secondary the rate of exposure to wood smoke. Two cohorts were analyzed, the first with patients without exposure to wood smoke and the second with no exposure.
Result:
The sample was formed by 68 men (55.3%) and 55 women (44.7%). They were smokers in 47.2% of the patients, with an average of 12.7 packs/year. The 47.15% had exposure to smoke from wood, with an average of 77.5 hours/year. The 88.6% had non-small-cell lung cancer (69.9% adenocarcinoma, 11.4% squamous and 7.3% other types), and 11.4% small cell lung cancer. The EGFR mutation was positive in 21% of adenocarcinomas. Patients with diagnosis of adenocarcinoma had the highest exposure to wood smoke (p<0.003). The cohort for exposure to wood smoke was significant for the development of lung cancer was 61 hours/year (p <0.001).
Conclusion:
The histological type of lung cancer most prevalent was adenocarcinoma, present in women with high exposure of wood smoke. The cohort of 61 hours/year was determined as a risk factor, the latter is not a predictor of EGFR mutation.
