Clinical trial

Screening of Tobacco-induced Cancers by Low-dose CT-scanner and Identification of Circulating Tumor Cells

Name
DETECToR
Description
Tobacco smoke is the most common source of exposure to carcinogens in humans. Indeed, the smoke contains about 1010 particles per ml and 4800 chemical compounds, at least 66 are carcinogenic. Tobacco smoke is the leading preventable cause of cancer in humans since it is responsible for lung cancer, upper aerodigestive tract (mouth, pharynx, larynx, esophagus), nasal cavity and sinuses, stomach, pancreas, liver, bladder, kidney, uterine cervix, and some myeloid leukemias. This study aims to evaluate the combined effect of the scanner and the search for circulating tumor cells (CTC) on screening for tobacco-related cancers, accompanying smokers to cessation and addressing the psychological impact this approach.

Psychological Questionnaires
The procedure of screening test could be stressful. "False positive" results can cause anxiety and lead to additional costs, as well as increased exposure to radiation and invasive medical examination. Although this is based on some objective results, there is a high probability of adverse psychological effects in case of false positives; so there is cause for concern in the short term anxiety associated with positive results and the use of additional tests during the intervals between screening phases. There is no data related to psychological distress potentially caused by the discovery of circulating tumor cells.
