| Abstract | Purpose: There is no agreement on the most appropriate post-operative pathway for the management of positive margins after laser cordectomy for early stage glottic tumours (T1-2N0M0). This literature review and meta-analysis aim to evaluate the post-operative treatment with the best oncological results among follow-up, radiotherapy (RT) and surgical second look. The parameters utilized were incidence of recurrence, overall (OS), disease-specific (DSS) and disease-free (DFS) survival and larynx preservation (LP). Methods: The articles were found through a string typed into PubMed from 2007 to 2022. The studies with detailed oncological results were selected according to inclusion criteria, and then the meta-analysis was carried out. Results: Sixteen studies met the inclusion criteria for 2808 patients. The positive margin was found in 748 patients (26.6%), of which 416 were referred to follow-up, 89 to RT and 242 to a surgical second look. A false positive margin was found in 58/104 patients (56%). The recurrence rate in patients with positive margins was significantly higher (p = 0.003). In OS, DSS, DFS and LP, the odds ratio (OR) value was always greater than 1, assessing the role of the positive margin as a risk factor. Conclusions: Prospective studies will be necessary to establish the role of positive margin as a prognostic factor. A surgical second look in case of positive margin seems to be the best option for the patient in terms of lower risk of recurrence and better oncological results. Better collaboration between surgeon and pathologist would be desirable to limit the real and false positive margins. |
