About this study
Official title: ProCaLung - Project on Cancer of the Lung : A National Radiotherapy Quality Assurance for Stage III NSCLC
ProCaLung is a national registry collecting radiation treatment parameters of patients having lung cancer that extends to mediastinal lymph nodes. The project includes a peer review activity.
The purpose of this public health program is similar to an audit whose objective is to promote quality of radiation oncology in Belgium. It is run by Institut Jules Bordet on behalf of the College of Physicians for Radiotherapy Centers of the Belgian Health Federal Public Service, in close collaboration with the Belgian Cancer Registry.
All Belgian radiotherapy centers are invited to participate in ProCaLung but their participation is not mandatory. The centers who accept to participate show a commitment to quality assurance as the radiotherapy-treatment-related parameters they generate will be analyzed to establish national statistics. It includes a peer-review process based on international guidelines for mediastinal nodes delineations given for informational purposes. The public interest program also collects technical parameters as they were planned and delivered during the course of chest radiation treatment. This includes the delineations of tumors, nodes and chest organs on simulation-CT images, PET/CT images, chest-CT images and the clinical information related to the lung cancer. Results/statistics will be published at the end of the project.

- Dosimetry [Non-inferiority, comparison of groups by final review group]: Mean Lung Dose, Lung V20Gy, Lung V30Gy, Mean Heart Dose, Esophagus V60Gy.
- Waiting times, use of contrast-enhanced CT, ITV, overall treatment time, proportion of treatments with recommended organs at risk delineated, radiological treatment completion rate, chemotherapy (and immunotherapy) completion rate, use of static/rotational intensity modulation, availability of data in the electronic health record.
Measured: 1 year
descriptive statistics for QA (no sample size needed)
- Waiting times, use of contrast-enhanced CT, ITV, overall treatment time, proportion of treatments with recommended organs at risk delineated, radiological treatment completion rate, chemotherapy (and immunotherapy) completion rate, use of static/rotational intensity modulation, availability of data in the electronic health record.
Measured: 2 years
Secondary outcomes (2)
Secondary endpoints related to standardization

- Proportion of treatments with initial review group 1 or 2 in start and end cohorts.
- Proportion of treatments with final review group 1 or 2 in start and end cohorts.
- Distribution of indicators of change in start and end cohorts.
- Conversion rates of review group 3a to review group 1, review group 4 to review group 1, and review group 4 to review group 3a.
- Distribution of the reasons for the impossibility to review the target definition.
Measured: 1 year
Secondary endpoints related to outcomes
- Toxicity [Comparison of final review groups]: Grade 3+ esophageal toxicity, Grade 3+ pulmonary toxicity (clinical and radiological), Other Grade 3+ toxicity.
- Pattern of locoregional failure (including relation to CTV),
- Progression free survival
- Overall survival.

The record says: status not confirmed, as of the sponsor's last update on 12 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Luigi Moretti, MD, PhD (+3225413800, Luigi.moretti@bordet.be), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
descriptive statistics for quality assurance (no sample size needed) (time frame: 1 year). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jun 2023; AzTrials last refreshed its copy on 7 Nov 2026.
