Chest wall resection is performed for a variety of diseases, for primary rib and soft tissue tumors, metastatic lesions, or locally invasive growth of lung and mediastinal tumors being the most common indications. Following the resection phase, it is essential to determine the method of chest wall reconstruction that will restore the structural function, preserve pulmonary biomechanics, reduce the likelihood of residual pleural space, pulmonary hernia, and protect intrathoracic organs. The main objective of this study is to investigate the outcomes of chest wall resection with reconstruction using Codubix material.

MATERIAL AND METHODS

This retrospective multicenter study included 22 patients who underwent chest wall tumor resection with subsequent Codubix rib endoprosthesis reconstruction from 2019 to 2023. Four medical institutions participated in the study: P.A. Herzen Moscow Cancer Research Institute, Sverdlovsk Regional Oncology Hospital, Morozov Children’s City Clinical Hospital and Kaluga Regional Oncology Hospital. Inclusion criteria were the presence of chest wall tumors, both primary and secondary, removal of more than 2 ribs, resection of the rib arch and the sternum.

RESULTS

The median age was 60 years (48—66), 11 (50%) patients were females and 11 (50%) males. Operations for chest wall sarcoma, metastatic lesions, and lung cancer were performed in 9 (40.9%), 4 (18.2%), and 3 (13.6%) patients, respectively. The median number of removed ribs was 3 (2—4), with a maximum of 7. Sternotomy was performed in 9 (40.9%) patients, and subtotal resection of the body or handle of the sternum was carried out in 77.7%. Combined resections were performed in 14 (63.6%) patients. Radical tumor removal (R0) was achieved in 21 (95.5%) patients. Complications were observed in 9 (40.9%) patients, with intermuscular seroma being the most common in three (33.3%), followed by hydrothorax in 2 (22.2%), bilateral pneumonia, acute respiratory failure, and postoperative delirium in 1 (11.1%) patient each. One patient had the Codubix plate removed due to postoperative wound infection. The median overall and recurrence-free survival was not reached, and the 1-year recurrence-free survival was 63.9%, with an overall survival of 86.8%.

CONCLUSION

Reconstruction with Codubix material allows for satisfactory functional and cosmetic results, characterized by a low complication rate and good adaptive properties.
