A Study to Screen for Lung Cancer in High-risk Individuals Who Have Never Smoked Using Low-dose Computed Tomography (LDCT). (NEMO)
LungScreen-NEMO: Prospective National Lung Cancer Screening Study in High-risk Never-smokers
A prospective, multicenter, national, observational study involving primary data collection to evaluate the lung cancer detection rate in high-risk never-smokers undergoing LDCT screening, with an exploratory evaluation of an artificial intelligence tool applied to imaging and blood collection for future ctDNA analysis

The study population will consist of never-smokers who have at least one prespecified high-risk factor for lung cancer, recruited from approximately 10 Brazilian centers.
Opis
Inclusion Criteria:
- - Sign and date the informed consent form before any study-specific procedure.
- - Be a never-smoker, defined as an individual who has smoked fewer than 100 cigarettes in their lifetime and who has no history of regular use of cigars, pipes, straw cigarettes, or hookahs.
- - Men aged 50 to 74 or women aged 40 to 74 at the time of enrollment.
- - Meet at least one of the following high-risk criteria: A first-degree relative or two second-degree relatives diagnosed with lung cancer; Current or previous occupational exposure to asbestos, nickel, arsenic, beryllium, silica, or chromium for at least 1 year; Exposure for more than five years to household smoke from coal or firewood, foundry smoke, or comparable industrial smoke; Known germline mutation in genes associated with an increased risk of lung cancer, including TP53, BRCA1, BRCA2, or ATM.
- - Be physically and medically capable of undergoing a chest CT scan in the supine position.
- - Be available for follow-up according to the study schedule.
Exclusion Criteria:
- - Previous diagnosis of invasive cancer, except for in situ neoplasms or treated non-melanoma skin tumors, when deemed clinically irrelevant by the investigator.
- - History of using cigars, pipes, straw cigarettes, or hookahs on more than 100 occasions throughout their lifetime, or regular use (≥ 1 time per week for ≥ 6 consecutive months).
- - Physical inability to remain in the supine position during a chest CT scan.
- - Inability to understand, sign, or maintain informed consent.
- - A clinical condition that, in the investigator's judgment, precludes the safe performance of study procedures or the planned follow-up.

Detection rate of confirmed lung cancer among screened participants
Ramy czasowe: From baseline assessment through the 24-month follow-up period.
|
The primary objective is to determine the detection rate of lung cancer, with an emphasis on early-stage disease, in high-risk never-smokers undergoing LDCT screening. The analysis will estimate the rate as the number of participants with a confirmed diagnosis divided by the number of enrolled participants who underwent baseline LDCT. |
From baseline assessment through the 24-month follow-up period.
