This prospective randomized pilot trial will evaluate a multiple intervention program of prevention in lifelong smokers aiming at reduction of chronic inflammation status through treatment with low-dose acetylsalicylic acid (ASA), smoking cessation with cytisine, targeted modification of diet and physical activity, in addition to early diagnosis with annual ultra low-dose spiral computed tomography (LDCT).

The most recent population-based studies carried out in Europe and the US on hundreds of thousands of individuals have unequivocally identified three principal causes of mortality, morbidity and chronic disability: tobacco smoke, inadequate diet, and reduced physical activity. These risk factors are in large part reversible, because in heavy smokers, even after 60 years of age, cessation is associated with a clear reduction in all-cause mortality. The finding that lifestyle and eating habits are associated with the development of cancer has been confirmed in many studies: smoking, a sedentary lifestyle, excess red meat, processed foods and sugars are associated with increased risk, while an active lifestyle, non-exposure to smoke (both active and passive), consumption of whole grains, legumes and vegetables are associated with protection or a reduced incidence in at-risk subjects.

What is clear, and confirmed by many studies, is that cancer occurs more often in overweight individuals, and that cancer patients who are overweight have more difficulty treating their disease. Elevated plasma levels of C-reactive protein (CRP), even when still within normal limits, are the reflection of a chronic state of inflammation and are associated with poor prognosis in several tobacco-related diseases. CRP measurement is besides a simple test to predict the risk of heart attack and stroke as well as mortality from all causes and from cardiovascular disease. In a systematic review on adult solid tumors, elevated CRP levels were associated with higher mortality and recurrence rates, and this observation was confirmed in early-stage lung cancer by a recent meta-analysis. In patients with chronic obstructive pulmonary disease (COPD), high CRP is a strong and independent predictor of future morbidity and mortality, and an increase in CRP concurrent with a reduction of the forced expiratory volume in 1 second (FEV1) shows an even stronger effect on patient's outcome.

High levels of CRP are associated with poor prognosis in cancers of the upper aerodigestive tract, rhinopharynx, lung and urinary tract. From a dietary point of view, consumption of saturated fats has been directly associated with an increase in inflammatory status as measured by high levels of CRP, just like consumption of meat, while an inverse correlation with consumption of vegetables has been observed. For example, low levels of inflammatory factors have been found in individuals adhering to a Mediterranean diet. Another recurrent finding, at least for cancer, is the importance of daily physical activity, such as brisk walking for 30 minutes. Moreover, regular physical activity is associated with better prognosis and increased survival in patients with a cancer diagnosis.

The number of heavy smokers that will participate in early-diagnosis programs using spiral CT will undoubtedly increase in the future as a result of awareness campaigns, and the participating volunteers represent an excellent opportunity to evaluate the efficacy of targeted primary prevention programs.

The present program will combine several interventions according to the randomization arm, proposed in combination or in single treatment, including treatment with cytisine, reduction of chronic inflammation by treatment with low-dose aspirin (ASA), targeted modification of diet and physical activity, in addition to early diagnosis with annual ultra low-dose spiral computed tomography (LDCT).

At baseline each volunteer will undergo:

* questionnaires on population evaluation (e.g. socio-demographic, smoking habits, physical activity, etc)
* blood sampling for the assessment of the inflammatory and metabolic profile
* evaluation of respiratory function and measurement of carbon monoxide (CO)
* thorax ultra low-dose computed tomography (LDCT) without contrast
* anthropometric evaluation (e.g. weight, height, BMI, etc)

To reduce levels of chronic inflammation will be used:

* treatment with low-dose acetylsalicylic acid (ASA)
* dietary / nutritional intervention in order to promote an optimal diet, based on characteristic of the Mediterranean Diet, for weight maintenance, visceral fat control and an adequate nutritional status
* physical activity intervention, through the reduction of sedentary behaviour and the implementation of a moderate intensity activity of about 30 min a day

In the Smoking cessation will be used Cytisine. It is a molecule known since the early 60s for the treatment of smoking. In recent clinical trials it revealed efficacy in smoking cessation. In 2014, the NHS (National Health Service) produced a document evaluating the cost-effectiveness of drug treatment of smoking, concluding that cytisine has the most favorable profile among the drugs taken into consideration

The imaging will be performed by volumetric acquisition with a computed tomography scanner equipped with advanced technology hardware and software, including: high performance X-ray tube with low potential, high sensitivity detectors combined with dedicated reconstruction algorithms for optimisation of the signal to noise ratio within an ultra low radiation dose. The protocol for ultra-low dose computed tomography will be specifically set for lung cancer screening with semiautomated image analysis and nodule quantification, according to the international standard for image quality (Quantitative Imaging Biomarker Alliance). In particular, the ultra-low dose computed tomography protocol will be developed for the lowest radiation exposure and tested by dedicated phantom for quantitative analysis of imaging metrics.

In the control group subjects will receive an information booklet containing advice on an optimal lifestyle with particular reference to smoking, diet and physical activity according to the best international guidelines.

Screening and Multiple Intervention on Lung Epidemics

Multifactorial Intervention of Primary Prevention in High Risk Subjects: a Randomized Trial

Reduction in the percentage of subjects with CRP\>=2 mg/L

Dietary intakes are collected by a self reported food frequencies questionnaire and data are expressed as the average daily/weekly consumption of foods and food groups.

Servings size is defined as "natural unit" (e.g. 1 glass of soft drinks, 1 teaspoon of sugar) or as an average serving (e.g. 80 g of pasta or rice, 30 g of dried fruits).

The frequency of serving size is reported as continuous measure. Data will be collected as continuous measures and will be analyzed by performing statistical models to investigate a potential relationship among changes in dietary habits and anthropometric parameters (BMI, waist circumference..), socio-demographic characteristics (gender, smoking status, physical activity), biochemical parameters (CRP blood levels), drugs assumption and the risk of chronic diseases, such as lung cancer.

Increase in the physical activity measured by the validate short form IPAQ questionnaire (International Physical Activity Questionnaire) The items in the short IPAQ form were structured to provide separate scores on walking, moderate-intensity and vigorous-intensity activity. Computation of the total score requires summation of the duration (in minutes) and frequency (days) of each activity.

METs are multiples of the resting metabolic rate and a MET-minute is computed by multiplying the MET score of an activity by the minutes performed:

* Walking MET-minutes/week = 3.3 \* walking minutes \* walking days
* Moderate MET-minutes/week = 4.0 \* moderate-intensity activity minutes \* moderate days
* Vigorous MET-minutes/week = 8.0 \* vigorous-intensity activity minutes \* vigorous-intensity days
* Total physical activity MET-minutes/week = sum of Walking + Moderate + Vigorous MET-minutes/week scores

Weight and height will be combined to report BMI in kg/m\^2. Reduction in BMI
