Background
Recent literature shows that tumor volume (TV) in T3 laryngeal squamous cell carcinoma (LSCC) is associated with response to radiation therapy. The aim of this study was to evaluate the effect of TV on survival outcomes in patients undergoing total laryngectomy (TL).
Methods
One hundred and seventeen patients with LSCC undergoing TL between 2013 and 2020 at the University of Florida were included. TV was measured using a previously validated method on preoperative‐CT scans. Multivariable CoxPH models for overall survival (OS) and disease‐specific survival (DSS), metastasis‐free survival (MFS), and recurrence‐free survival (RFS) were developed with TV.
Results
Mean age was 61.5 years and 81.2% were male. Higher TV was associated with decreased OS, MFS, DSS, and RFS with adjusted hazard ratios 1.02 (95%CI: 1.01, 1.03), 1.01, (95%CI: 1.00, 1.03), 1.03 (95%CI: 1.01, 1.06), and 1.02 (95%CI: 1.00, 1.03) respectively. TV >7.1 cc had worse prognoses.
Conclusions
TV appears associated with decreased survival in LSCC treated with TL.
