Objective:
The study is a retrospective comparison of the usefulness of salvage surgery between a group of previously radiotherapy-treated patients (RTPs) and a group of patients who previously underwent partial surgery with both local and ± nodal recurrence.
Study Design:
Retrospective study.
Setting:
Multi-center academic hospital.
Materials And Methods:
The former group was comprised 30 previously RTPs, whereas the latter group consisted of 20 patients after partial laryngeal surgery with optional subsequent adjuvant radiotherapy (PSPs). Treatment efficacy was compared in both groups in relation to overall survival (OS) and the locoregional control rate (LCR). Local and ± nodal recurrence was considered primary treatment failure. All patients underwent total laryngectomy.
Results:
The updated 5-year OS in the PSPs was 31%, while the percentage of the updated 5-year LCR was 42%. In the RTPs the updated 5-year OS was 21%, and the percentage of 5-year LCR was 38%. No statistically significant differences were found in terms of the comparison of OS or the comparison of LCR results in both groups (P = 0.427, P = 0.704, respectively).
Conclusions:
Based on the analysis, it was found that irrespective of the initial treatment, salvage surgery was associated with decreased survival and cure rates (by 50%) compared to the group of patients with advanced laryngeal cancer who underwent primary total laryngectomy.
