Conclusions Sampling surgical margins in trans-oral laser microsurgery for early glottic squamous cell carcinoma (SCC) may allow for increased local control rate, although with no difference in local control by endoscopic treatment alone. Objective To further delineate the role of routinely sampling separate surgical margins, in patients with early glottic SCC undergoing endoscopic laser resection. Methods A retrospective case control study. One hundres and two early glottic cancer patients staged Tis-T2 underwent endoscopic laser surgery with curative intent as the primary treatment. Separate margins from the surgical bed were sampled following complete tumor resection in 64 patients; in 38 patients no margins were sampled. Results Margin sampling showed a tendency towards reduced risk for local recurrence, adjusted HR = 0.439 (p-value = 0.096). However, there was no difference in local control by endoscopic treatment alone. The patients with sampled margins were further divided based on margins status: 39 (61%) had negative margins, and 25 (39%) had positive margins. Compared with negative margins, patients with positive margins showed increased risk for recurrence, adjusted HR = 8.492 (p = 0.008). When margins were not sampled the risk for local recurrence was increased compared to negative margins (adjusted HR = 7.875, p-value = 0.008), and relatively comparable to what was observed when sampled margins were positive (adjusted HR = 0.927, p-value = 0.88).
