Background:
Pulmonary metastasectomy (PM) is an important procedure for the treatment of metastatic nodules in the lung. The choice of surgical approach, whether thoracotomy or video-assisted thoracoscopic surgery (VATS), remains controversial in terms of the impact on patient prognosis.
Objectives:
This study aimed to evaluate the outcomes and impact on survival of patients undergoing PM with VATS compared to thoracotomy.
Material And Methods:
A retrospective evaluation of 136 patients who underwent PM between September 2012 and July 2020 was performed. Data on the demographics, primary tumor histopathology, metastatic features, surgical approach, surgical outcomes, and survival status were analyzed. Statistical analyses included descriptive statistics, survival analysis and Cox regression models.
Results:
Of the participants, 84 underwent thoracotomy and 52 underwent VATS. The median survival time of thoracotomized patients was 86.6 months, while it was 99.6 months for VATS patients. A gender-specific analysis revealed a significantly longer survival time for female VATS patients compared to thoracotomy. Multivariate analysis showed significant independent effects of specific tumor types and the number of nodes removed on survival. Overall, no significant difference in survival was found between the 2 surgical methods.
Conclusions:
Both VATS and thoracotomy are effective and safe options for PM. Video-assisted thoracoscopic surgery may offer advantages, particularly in certain patient groups and tumor types, potentially prolonging survival. Gender-specific analyses suggest a survival benefit of VATS, particularly in women. Further studies are needed to validate these results and optimize surgical decision-making in PM.
