Abstract

Introduction: The benefits of routine follow-up after treatment of primary laryngeal squamous cell carcinoma (LSCC) remain disputed. Guidelines worldwide are consensus-based, and evidence for specific subgroups is lacking. This study evaluates routine LSCC follow-up including flexible endoscopy for detecting locoregional recurrence (LRR).

Methods: A retrospective cohort of 413 LSCC patients treated between 2006 and 2012 was analysed. The cumulative risk of LRR was calculated. Routine follow-up was evaluated by follow-up visit (routine or interval) at which LRR was detected, LRR treatment intent, and overall survival (OS). Analyses were stratified by early (I-II) and advanced (III-IV) TNM-stage.

Results: There were 263 (64 %) patients with early-stage and 132 (32 %) patients with advanced-stage LSCC. One-, two- and five-year cumulative risks for LRR after early-stage LSCC were 8 %, 18 %, and 26 %. For advanced-stage LSCC, cumulative risks of LRR were 20 %, 30 %, and 35 %. Of all 69 LRRs after early-stage LSCC, 72 % were routine-detected, 81 % were symptomatic, and 90 % received curative-intent treatment. Of all 45 LRRs following advanced-stage LSCC, 42 % were routine-detected, 84 % were symptomatic, and 62 % received curative-intent treatment. Five-year OS of early-stage LSCC with routine-detected LRR was 70 %, and 72 % for interval-detection (log-rank-p = 0.91). Five-year OS of advanced-stage LSCC with routine-detected LRR was 37 %, and 18 % for interval-detection (log-rank-p = 0.06).

Conclusions: Routine follow-up for detecting asymptomatic recurrences seems redundant for early-stage LSCC. After advanced-stage LSCC, no asymptomatic recurrences were detected beyond one year posttreatment despite regular follow-up. Emphasis should be on other follow-up aspects, such as psychosocial support, especially after one year posttreatment.
