Lung Cancer Screening Program Using Low-dose Tomography and Metabolomic Evaluation in a Public Service.
- Conditions
- Lung Cancer
- Registration Number
- NCT06376097
- Lead Sponsor
- AstraZeneca
- Brief Summary
Observational study that aims to evaluate the implementation of a lung cancer screening program in a smoker population included in a public heath service.
- Detailed Description
Patients' clinical data (recruited from the outpatient clinics and wards of Hospital das Clínicas from the Faculty of Medicine of Botucatu) will be collected in a specific form, developed to this work, containing the following data: demographic characteristics (name, age, sex, race, profession, marital status, monthly income and education), main diagnosis and diseases associated, assessment of comorbidities using the Charlson Index, and Hospital Health Scale.
Anxiety and Depression (HAD Scale), use of maintenance medications, history of smoking (active or not, calculation of smoking load), body composition (mass index body- BMI calculation) and pulse oximetry measurement. All patients included will undergo low-dose radiation tomography and spirometry. All patients active smokers, who wish to stop smoking, will be referred to the outpatient clinic smoking cessation. Specific measurements will be applied if there is a diagnosis of COPD by spirometry (the BODE Index questionnaires, Dyspnea Index-Medical Modified Research Council, TC6) and patients will be referred to the outpatient clinic specific COPD for follow-up in the service. Subsequently, the anxiety and depression assessments. The tracking protocol will follow the recommendations of repeat the low-dose radiation chest tomography every year, if normal, until complete two years of follow-up. In this case, the patient will be discharged from the tracking. If the patient presents changes in the tomography, follow-up protocol according to the size of the lesions will be carried out. Morbidity and mortality assessment will be carried out in patients diagnosed with lung cancer.

- Primary Outcome Measures
Name Time Method Absolute number and frequency of false-negative lung nodules . Dec, 2024 Determine the prevalence of pulmonary nodules identified in the target population and the rate of false negative ones. Patients with suspicious nodules will be referred for transthoracic biopsy guided by tomography or a surgical biopsy.
- Secondary Outcome Measures
Name Time Method Assessment of morbidity and mortality in patients undergoing invasive procedures, whether diagnostic or therapeutic. Dec, 2024 The evaluation of morbidity and mortality will be objectively measured by the following calculations:
-Morbidity: number of individuals who underwent an invasive procedure and who had complications / number of individuals who underwent an invasive procedure.
Mortality: number of individuals who underwent an invasive procedure and died due to the procedure or a later compliaction / number of individuals who underwent an invasive procedure.
Examples of complications after such procedures are: pneumonia after bronchoscopy or surgical procedures, pneumothorax and bleeding after bronchoscopy, surgical wound infection after surgical procedures, pneumothorax and hemothorax after transthoracic biopsy and death resulting from any invasive procedureCost comparasion of treating patients in metastatic setting vs. treating early-stage lung cancer patients, including all costs from the screening program. Dec, 2024 The costs of the screening program will comprise the following: medical consultations and by the multidisciplinary team, spirometry and CT scans. And when necessary, hospitalizations and invasive exams for the etiological investigation of the changes found in CT scans, such as bronchoscopy, transthoracic biopsy or surgical procedure.
All costs from the program and treatment of early-stage diagnosed patients will be compared with a patient seen and treated in advanced stages of lung cancer (historical data). All costs will be estimated using data from hospital records.Assess adherence to smoking cessation treatment in active smokers who enter screening. Dec, 2024 Adherence to smoking cessation treatment will be objectively measured by the following calculation: number of smokers who stopped smoking after inclusion in the screening project / total number of mokers included. Information on smoking cessation will be extracted from the patient's medical record, from medical appointment carried out by the pulmonology team.
