Racial/Ethnic Differences in Lung Cancer Incidence in the Multiethnic Cohort Study: An Update.

ABSTRACT:

Background

We previously found that African Americans and Native Hawaiians were at highest lung cancer risk compared with Japanese Americans and Latinos; whites were midway in risk. These differences were more evident at relatively low levels of smoking intensity, fewer than 20 cigarettes per day (CPD), than at higher intensity.

Methods

We apportioned lung cancer risk into three parts: age-specific background risk (among never smokers), an excess relative risk term for cumulative smoking, and modifiers of the smoking effect: race and years-quit smoking. We also explored the effect of replacing self-reports of CPD with a urinary biomarker-total nicotine equivalents-using data from a urinary biomarker substudy.

Results

Total lung cancers increased from 1979 to 4993 comp
