Searching for evidence of VATS lung metastasectomy

Abstract

We are pleased to introduce this issue devoted to video-assisted thoracic surgery (VATS) for lung metastases. Although not confirmed with prospective randomized trials, pulmonary resection(s) is the operation of choice for lung metastases with a relatively low postoperative complication rate. Nonetheless, the surgical approach to perform lung metastasectomy remains a point of debate as VATS or open transthoracic approach can both be performed. Though surgeons are looking for reliable data in favor of VATS for lung metastasectomy, there is scarce prospective data and most available practices raise questions (1) instead of giving answers. Nevertheless, after 10 years of ESTS project dedicated to lung metastases (2), this special issue dedicated to VATS metastasectomy, which also includes exceptional videos, will help to publicize important experiences, and will also stimulate young surgeons, oncologists and scientists to find new ideas for the future. There will also be an article which reports on the TNM classification for lung metastases which we initially proposed in 2016 (3). It could be an easy way to finally “personalize” the treatment of the difficult patients with lung metastases (4). One thing is certain, in the absence of scientific evidence that demonstrates that one approach (open or VATS) is better than the other, the less invasive approach should be chosen. Therefore, there is no doubt that VATS (uniportal, multiportal or subxiphoid) represents nowadays the most used “standard practice” to remove lung metastases. Nevertheless, surgeons should never forget that the fundamental goal of the procedure of lung metastasectomy is not the minimal invasiveness of the skin incision but the prolonged survival. We are in debt of gratefulness to the outstanding contributors for offering their knowledge and practice with lung metastasectomy. Finally, we would like to acknowledge Video-Assisted Thoracic Surgery (VATS) journal for allowing us organize this important special issue and for the exceptional work done by all the staff.
