Pharyngocutaneous fistula (PCF) results in an inflammatory reaction, but its association with the rate of locoregional and distant control, disease-free survival, and overall survival in laryngeal cancer remains uncertain.

We determine if pharyngocutaneous fistula after salvage laryngectomy is associated with locoregional and distant control, disease-free survival, and/or overall survival.

A multicenter collaborative retrospective cohort study conducted at 5 centers in Canada and the US of 550 patients who underwent salvage laryngectomy for recurrent laryngeal cancer from January 1, 2000, to December 31, 2014. The median follow-up time was 5.7 years (range, 0-18 years).

examined included locoregional and distant control, disease-free survival, and overall survival.

Fine and Gray competing risk regression and Cox-proportional hazard regression models were used for outcomes.

Competing risks and the Kaplan-Meier methods were used to estimate outcomes at 3 years and 5 years.
