OBJECTIVE: We aimed to evaluate the prognostic factors and efficacy of treatment modalities for patients with temporal bone cancer, and to determine if definitive chemoradiotherapy (CRT) for advanced-stage disease can provide a substitute for highly invasive surgeries. STUDY DESIGN: Retrospective case series. SETTING: Tertiary referral center. PATIENTS: Sixty-six patients with previously untreated squamous cell carcinoma of the temporal bone treated with curative intent between April 1997 and March 2015. INTERVENTION: Surgery alone, radiotherapy (RT) alone, surgery followed by RT or definitive CRT. MAIN OUTCOME MEASURE: The overall survival (OS) rate. RESULTS: The 5-year OS rate for each T classification was 100% for T1, 76.2% for T2, 55.6% for T3, and 36.7% for T4. Univariable and multivariable analysis showed that T classification was an independent predictor of the OS rate (hazard ratio 5.66; 95% confidence interval 1.51-27.0; p = 0.015). Analysis by treatment modality revealed that the 5-year OS rate for patients with T1-2 was 100% for surgery and 81.3% for RT alone. The rate for patients with T3-4 was 52.1% for definitive CRT and 55.6% for surgery followed by RT with or without chemotherapy. CONCLUSIONS: Patients with T1-2 benefited from surgical intervention without significant morbidity or mortality. Our findings also suggested that definitive CRT might be appropriate as the first-line treatment for T3-4, especially in cases with unresectable tumors.
