Abstract
OBJECTIVE: The goal was to identify factors associated with the outcome of salvage therapy for patients with isolated cervical recurrences of squamous cell carcinoma in the previously treated neck (ICR-PTN). STUDY DESIGN AND SETTINGS: A tumor registry search for ICR-PTN patients was performed at 7 participating institutions, and the charts were reviewed. Kaplan-Meier plots for survival and time until rerecurrence were used to evaluate the significance of associated variables. RESULTS: Median survival and time until re-recurrence were both 11 months. Survival was better in patients with the following characteristics: nonsurgical initial neck treatment, negative initial disease resection margins, no history of prior recurrence, ipsilateral location of the ICR-PTN relative to the primary, and use of surgical salvage. CONCLUSIONS: By pooling the experience of 7 US tertiary care medical centers, we have identified 5 factors that are associated with outcome of salvage therapy for ICR-PTN. SIGNIFICANCE: Consideration of these factors, as well as the reviewed literature, should facilitate patient selection for salvage protocols. (Otolaryngol Head Neck Surg 2000; 123:368-76.)
