Abstract
The purpose of this work is to evaluate the utilization of information gathered by
multiphasic screening with respect to lung cancer detection and smoking cessation
techniques. A cohort (follow-up) study is reported in which cancer incidence and factors
affecting its occurrence are evaluated in a group of about 20,000 presumably healthy
adults along a period of approximately 10 years following comprehensive multiphasic
health examinations. Lung cancer occurrence is primarily related to smoking. The risk
is higher in smokers and is dose-dependent; OR = 0.21, (CI = 0.08,.53) in never smokers,
OR = 1.53 (CI = 0.8,3.2) in past and current moderate smokers, OR = 4.92 (CI = 2.18,11.11)
in current heavy smokers. Moreover, smokers with compromised pulmonary function (FEVI/FVC
< 75%) are at an even higher risk of developing lung cancer OR = 4.22 (CI = 2.2, 8.2)
for past and current moderate smokers; and OR = 10.7 (CI-2.5, 38.6) in current heavy
smokers. Information gathered in periodical multiphasic health examinations could
be utilized by health professionals to encourage smoking cessation and smoking prevention
in the appropriate screenees. Various elements of the multiphasic test results could
contribute to such prevention efforts. While every smoker should receive appropriate
evaluation and consultation regarding nicotine dependence, smokers with reduced pulmonary
function represent an extra high risk group to which special attention should be given.
