Optimizing Bronchopulmonary Cancer Screening (OPTI-DEPIST)

May 29, 2026 updated by: Institut Curie

Optimizing the Implementation of Bronchopulmonary Cancer Screening in the Ile de France Region (OPTI-DEPIST-MUT)

The aim of this study is to evaluate the feasibility of performing a first screening for bronchopulmonary cancer by thoracic scanner in a French cohort within a dedicated, effective and structured network in the pilot centers participating in the study.

Study Overview

Detailed Description

The organization of bronchopulmonary cancer screening in the Ile de France region, within the Mutualists and its affiliated health centers, is based on a clear, simple and functional process:

  • Definition of eligibility criteria for screening, based on those of the NELSON study,
  • Referral and consultation by a health center physician trained in these criteria,
  • Referral and performance of a chest Computer Tomography Scanner (CTscan) according to the same recommendations,
  • Structured centralized reading and interpretation of CTscan images,
  • Referral to a multidisciplinary team (CITT), if bronchopulmonary cancer is suspected,
  • Referral to a tobacco unit in a health center for smokers who have not stopped smoking,
  • Organization of follow-up and continuation of the screening program.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Participant aged 50 to 74.
  • Resident in the Île-de-France region.
  • Active smoker or quit smoker for 10 years or less:

    1. more than 10 cigarettes a day for more than 30 years,
    2. more than 15 cigarettes a day for more than 25 years.
  • The participant has been informed and has signed the consent form.
  • Social Security System affiliation.
  • Willingness to participate in a smoking cessation program, if currently smoking.

Exclusion Criteria:

  • Active cancer or a history of cancer in remission for less than 5 years (except basal cell carcinoma of th skin or epithelioma in situ of the uterine cervix).
  • Presence of symptoms suggestive of bronchopulmonary cancer. Participants with these symptoms require immediate diagnostic investigations and are therefore not eligible for screening.
  • Weight >= 140 kg.
  • Severe comorbidity contraindicating therapeutic options or invasive thoracic diagnostic investigations.
  • Inability to climb two flights of stairs without stopping.
  • A thoracic CTscan performed within the previous year.
  • Persons deprived of liberty or under guardianship.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: Screening for primary prevention of bronchopulmonary cancer
Screening CTscan according to the NELSON trial schedule (at inclusion, 1 year, 3 years, 5.5 years),
A first step to identify and recruit people eligible for screening,
A second step for inclusion of participants, with an online self-questionnaire and information, and an inclusion visit to the health center,

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Rate of first CTscan for bronchopulmonary cancer screening
Time Frame: 36 months

Rate of complications related to complementary explorations
Time Frame: 102 months
Ratio between the number of people with complications related to complementary explorations and the population having undergone a CT scan.
