Prognostic impact of initial treatment in surgically salvaged recurrences of early glottic cancer

Objective

The purpose of this study was to analyze the outcomes of surgically salvaged early glottic cancer (EGC) recurrences after initial radiotherapy (RT) or transoral laser microsurgery (TLM).

Methods

A matched pair analysis by recurrent tumor‐node‐metastasis stage (rTNM) considering 27 patients who had TLM as initial treatment and 54 patients who failed after primary RT was performed. Post‐recurrence overall and disease‐specific survival (DSS) were evaluated.

Results

The RT‐failed group showed worse post‐recurrence overall survival (P < .001) and DSS (P = .005) compared to TLM‐first group despite the same rTNM stage. The RT failed patients also showed more postoperative complications (longer mean decannulation time, P = .005; nasogastric feeding tube dependence, P = .012) and a higher rate of second locoregional recurrences (P = .004).

Conclusion

The RT‐failed EGC showed worse outcomes in terms of survival, complications, and locoregional recurrences compared to same recurrent TNM stage TLM‐failed cases.
