About this study

Official title: Dynamic Evolution of Pulmonary Nodules and Influence Factors of Its Clinical Decision-making: A Prospective Cohort Study

The researchers are aimed to investigate the dynamic evolution of indeterminate pulmonary nodules by a long-term follow-up of patients with different characteristics. Influence factors of clinical decision-making that might contribute to overtreatment or delayed treatment will also be studied.

Read the detailed description

This observatory study prospectively recruits patients with indeterminate pulmonary nodules identified in computed tomography (CT) scans from thoracic clinic. The radiological features and their chronological changes during follow-up period will be recorded in detail. Subgroup analyses will be performed based on the clinical and demographic characteristics of patients (including symptomatic information, comorbidities, family history, antibiotic usage, etc). Hospital Anxiety and Depression Scale (HADS) is collected from each patient at multiple time points to evaluate the patients' psychological status and its impact on clinical decision-making. The interaction analyses between individual characteristics (such as education level, occupation, disease cognitive level, etc) and Hospital Anxiety and Depression Scale will also be performed. The researchers aim to provide high-quality evidence for the formulation of a precise follow-up and management plan for patients with pulmonary nodules.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CT scanDiagnostic test

    For patients with low-risk pulmonary nodules, follow-up CT scan is recommended

  • AntibioticsDrug

    For pulmonary nodules with features of infectious disease, antibiotics is recommended

  • Surgical ResectionProcedure or surgery

    For persistent high-risk pulmonary nodules, surgical resection is recommended

Study groups in NCT04857333
Study groupRoleWhat they receive
Pulmonary NodulePatients are recommended for using antibiotics, solely follow-up or surgical resection according to the current clinical guideline for management of indeterminate pulmonary nodule. No intervention is administered for this observatory study.
Receives: Diagnostic Test: CT scan; Drug: Antibiotics; Procedure: Surgical Resection

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time to surgical resection

    Time calculated from the date of identification of pulmonary nodule to the date of surgical resection

    Measured: The date of first documented diagnosis of pulmonary nodule by CT scan to the date of surgical resection, up to 60 months

  2. Time to progression

    Time calculated from the date of identification of pulmonary nodule to the date of progression of pulmonary nodule based on evaluation of CT imaging

    Measured: The date of first documented diagnosis of pulmonary nodule by CT scan to the date of documented progression by CT scan, up to 60 months

Secondary outcomes (3)
  1. Proportion of malignancy

    Proportion of malignant findings by pathological examination in all patients receiving surgical resection

    Measured: The date of first documented diagnosis of pulmonary nodule by CT scan to the date of surgical resection, up to 60 months

  2. Change of Hospital Anxiety and Depression Scale-Anxiety (HADS-A) score

    The differences of Hospital Anxiety and Depression Scale-Anxiety (HADS-A) scores of the same patients before and after surgical resection. This 7-item checklist is a part of the Hospital Anxiety and Depression Scale, which is used for assessment for the status of anxiety. The maximal score for HADS-A is 21. Scores of greater than or equal to 11 on either scale indicate a definitive case. Scores of 0-7 are defined to be normal, while scores of 8-10 are defined to be borderline abnormal (borderline case).

    Measured: The date of enrollment in our cohort study when Hospital Anxiety and Depression Scale is measured to the date when primary endpoint( surgical resection) is reached, up to 60 months, with multiple measurements.

  3. Change of Hospital Anxiety and Depression Scale-Depression (HADS-D) score

    The differences of Hospital Anxiety and Depression Scale-Depression (HADS-D) scores of the same patients before and after surgical resection. This 7-item checklist is a part of the Hospital Anxiety and Depression Scale, which is used for assessment for the status of depression. The maximal score for HADS-D is 21. Scores of greater than or equal to 11 on either scale indicate a definitive case. Scores of 0-7 are defined to be normal, while scores of 8-10 are defined to be borderline abnormal (borderline case).

    Measured: The date of enrollment in our cohort study when Hospital Anxiety and Depression Scale is measured to the date when primary endpoint( surgical resection) is reached, up to 60 months, with multiple measurements.

What does the primary outcome measure?

Time to surgical resection (time frame: The date of first documented diagnosis of pulmonary nodule by CT scan to the date of surgical resection, up to 60 months). 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?

On the ClinicalTrials.gov record for NCT04857333, which also lists 2 linked publications.
