Study summary

This project focuses on patients with chest wall tumors who are expected to have a maximum intraoperative anterolateral chest wall defect diameter of 5-10 cm and require chest wall reconstruction with rib implants. It aims to evaluate the efficacy and safety of biodegradable 3D-printed implants in chest wall reconstruction surgery, providing a superior reconstruction strategy for patients with tumor-induced chest wall defects.

What researchers measure

Primary outcomes

  1. Abnormal breathing

    Observe the integrity of the chest wall shape and the presence of abnormal breathing

    Time frame: Postoperative 1 month, 3 months, 6 months, and 12 months

  2. Implant Degradation Performance Monitoring

    Thin-section chest CT + 3D imaging (DICOM format data) * Implant volume changes: Precise measurement of volumetric changes through 3D reconstruction; * Implant density changes: Quantification of density changes using Hounsfield Units (HU values), including adjacent bone tissue changes; ③ Bone resorption/formation: Observation of potential bone loss or new bone formation; ④ Implant structural integrity: Assessment for cracks, voids, or other structural compromises.

    Time frame: Postoperative 1 month, 3 months, 6 months, and 12 months

  3. Peri-implant Soft Tissue Evaluation

    Chest MRI to evaluate thickening of the pleural fibrous layer surrounding the implant

    Time frame: Postoperative 1 month, 3 months, 6 months, and 12 months

Secondary outcomes

  1. Changes in respiratory function--Pulmonary Function Test

    The assessment of changes in respiratory function through pulmonary function tests includes indicators such as Forced Vital Capacity (FVC), Forced Expiratory Volume in the First Second (FEV₁), Total Lung Capacity (TLC), Residual Volume (RV), and Maximum Voluntary Ventilation (MVV).

    Time frame: Postoperative 1 month, 3 months, 6 months, and 12 months

  2. Adverse events

    Time frame: form date of enrollment until the end of the study, assessed up to 12 months
