Palliative management of malignant airway obstruction

Background Obstruction of the airway due to unresectable malignant disease is a frightening condition that portends a poor prognosis. Endobronchial treatment modalities were reviewed to determine the most effective management strategy. Methods A 12-year retrospective review (1988 to 1999) of 121 consecutive patients with inoperable malignant airway obstruction (MAO) was performed. Sixty-five patients received high-dose-rate brachytherapy (HDR) alone, 32 received HDR plus neodymium:yttrium-aluminum garnet laser (YAG) therapy, 16 received YAG only, 4 patients were stented, and 4 received photodynamic therapy (PDT). Follow-up was obtained by chart review and contact. Results Seventy-seven men and 44 women, median age 62 years (range 30 to 86 years), underwent 378 endobronchial procedures for relief of MAO. Good to excellent results were achieved in 77% (93/121) of patients. Seventy-two percent (23/32) of patients undergoing HDR plus YAG received a good to excellent result. All 8 patients receiving either stents or PDT had good to excellent palliation. There were no intraoperative deaths, but there were two in-hospital deaths. Complications occurred in 4% (5/121) of patients. Forty-four percent (53/121) of our patients were lost to follow-up. Mean survival was 6.7 months after the last treatment. Conclusions Temporary relief of inoperable MAO can be accomplished with a number of endobronchial treatments used either singularly or in combination. The majority of patients managed with HDR, YAG, or HDR plus YAG received good to excellent short-term palliation.
