Predictors of survival after total laryngectomy for recurrent/persistent laryngeal squamous cell carcinoma

BackgroundTotal laryngectomy remains the treatment of choice for recurrent/persistent laryngeal squamous cell carcinoma (SCC) after radiotherapy (RT) or chemoradiotherapy (CRT). However, despite attempts at aggressive surgical salvage, survival in this cohort remains suboptimal.MethodsA prospectively maintained single‐institution database was queried for patients undergoing total laryngectomy for recurrent/persistent laryngeal SCC after initial RT/CRT between 1998 and 2015(n = 244). Demographic, clinical, and survival data were abstracted. The Kaplan‐Meier survival curves and hazard ratios (HRs) were calculated.ResultsFive‐year overall survival (OS) was 49%. Five‐year disease‐free survival (DFS) was 58%. Independent predictors of OS included severe comorbidity (Adult Comorbidity Evaluation‐27 [ACE‐27] scale; HR 3.76; 95% confidence interval [CI] 1.56‐9.06), and positive recurrent clinical nodes (HR 2.91; 95% CI 1.74‐4.88).ConclusionSevere comorbidity status is the strongest predictor of OS, suggesting that increased attention to mitigating competing risks to health is critical. These data may inform a risk prediction model to allow for focused shared decision making, preoperative health optimization, and patient selection for adjuvant therapies.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/139972/1/hed24918.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/139972/2/hed24918_am.pd
