Abstract
Objectives This article aims to clarify the long-term outcomes of patients with squamous cell
carcinoma of the temporal bone who underwent concomitant chemoradiotherapy (CCRT).
Design and Setting The study design was a retrospective chart review.
Patients and Methods From December 2001 to June 2014, 23 patients with cancer of the temporal bone who
were treated by CCRT at the Tohoku University Hospital and the Iwate Medical University
Hospital were enrolled in this study. For advanced cancer of the temporal bone, a
modified docetaxel, cisplatin, and 5-fluorouracil (TPF) regimen was used for CCRT.
The long-term outcomes, including prognoses and late complications, were analyzed
after CCRT of patients with cancers of the temporal bone.
Results The main long-term complications were stenosis of the external auditory canal and
conductive hearing loss. No harmful late complications were observed in these patients.
Disease-specific survival rates were 84.9% for all patients, 100% for patients of
stage I, II, and III (n = 10), and 75.5% for patients of stage IV (n = 13) at 5 years.
Conclusions Our study showed that CCRT is an effective treatment choice for squamous cell carcinoma
of the temporal bone. Furthermore, CCRT using the TPF regimen is a safe and effective
initial treatment for patients with advanced cancers of the temporal bone.
