Abstract

Highlights: Rate of surgical and medical complications was 50.0% and 27.2%, respectively. Predictors of surgical complications include young age and hypothyroidism. Predictors of medical complications include old age and history of liver disease. Medical complications are associated with worse 5-year overall survival. Surgical complications are not associated with worse 5-year overall survival. Abstract: Objectives: To investigate variables that predict medical and surgical complications in patients undergoing salvage surgery after primary organ-preserving therapy for head and neck cancer and to investigate the effect of complications on 5-year overall survival. Materials and methods: A retrospective study was conducted on patients undergoing salvage surgery after primary organ-preserving therapy for head and neck cancer at a tertiary institution from 2006 to 2011. Multivariable regression analysis was used to assess association between independent variables and medical and surgical complications. A Kaplan-Meier survival curve was plotted to assess effect of surgical and medical complications on 5-year overall survival. Results: One hundred thirty-six patients undergoing salvage surgery after primary organ-preservation surgery met inclusion criteria. Surgical complications occurred in 68/136 (50.0%) of patients. After adjusting for confounders, young age and history of hypothyroidism were significant predictors of surgical complications ( p < 0.05). Medical complications occurred in 37/136 (27.2%) of patients. After adjusting for confounders, older age and history of hepatic disease were significant predictors of having a medical complication ( p < 0.05). Patients with no complications had better overall survival than patients with medical complications (p = 0.009). There was no difference in overall survival between patients without complications and patients with surgical complications only (p = 0.259). Conclusion: Risk factors for medical and surgical complications include history of hypothyroidism, liver disease, and age. Survival outcomes are not affected by surgical complications but are significantly affected by medical complications highlighting the importance of personalized patient care and medical co-management.
