PurposeThe prognosis for primary tracheal cancer is dismal. We investigated whether there has been improvement in survival in tracheal cancer patients and how treatment modality affected overall and cancer-specific survival.Materials and methodsUsing the Surveillance, Epidemiology, and End Results database, 1144 patients with tracheal cancer were identified between 1973 and 2011. Patients were stratified by age group, gender, race, tumor histology, and treatment modality. Radical surgery and survival rates based upon these stratifications were determined. Longitudinal analyses of survival and the percentage of patients undergoing surgery and radiation were conducted.ResultsIn the final cohort, 327 tracheal cancer patients (34%) underwent radical surgery. Patients of younger age, female gender, and who presented with non-squamous cell tumors were statistically more likely to undergo surgery. Over time, utilization of radiation has declined while use of radical surgery has increased. Concomitantly, 5-year survival has increased from approximately 25% in 1973 to 30% by 2006. Those who did not have surgery were 2.50 times more likely to die of tracheal cancer (95% Confidence Interval 2.00–3.11, p<0.001) than those who did have surgery. Additionally, patients who underwent radical surgery alone (without adjuvant radiation therapy) were 50% or 19% less likely to die of tracheal cancer than those who underwent no treatment or combination therapy, respectively (both p<0.001).ConclusionsSurvival in patients with tracheal cancer is improving over time. The utilization of radical surgery is increasing and confers the highest survival advantage to patients who are candidates.
