Abstract

Introduction Transoral laser microsurgery (TLM) is the treatment of choice for Tis-T2 squamous cell glottic carcinomas due to its advantages compared with open surgery and radiotherapy. However, the CO(2)laser beam causes changes and damage on the specimens, making the histological assessment of resection margins, the gold standard for confirming radical tumor resection, sometimes difficult.Objective To assess the different ways to manage patients depending on the status of the histopathological margin according to recent studies to detect the most commonly shared therapeutic strategy.Data Synthesis We analyzed the literature available on the PubMed and Web of Science databases, including only articles published since 2005, using specific keywords to retrieve articles whose titles and abstracts were read and analyzed independently by two authors to detect relevant studies. Therefore, we focused on disease-free survival, overall survival, local control, laryngeal preservation, and disease-specific survival. Thus, 17 studies were included in the present review; they were grouped according to the status of the histological margin, and we analyzed the different management policies described in them. This analysis showed that there is not a shared strategy, though in most studies the authors performed a second-look surgery in the cases of positive margins and a close follow-up in cases of negative ones. The main disagreement is regarding the management of close or non-valuable resection margins, since some some authors performed a second-look surgery, and others, a close follow-up.Conclusions Definitely, the most shared policy is the second-look surgery in case of positive surgical margins, and a close follow-up in case of close or non-valuable resection margins.
