OBJECTIVE: To examine the risk of ocular complications following radiotherapy in patients with nasopharyngeal carcinoma (NPC).
METHODS: We adopted 1:1 propensity score matching and identified an NPC cohort (n = 736) and a comparison cohort (n = 736) that comprised non-NPC head and neck cancer patients who received radiotherapy in the National Health Insurance Research Database from 1997 to 2010. The follow-up period was terminated upon developing ocular complications (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM]360-379) or on December 31, 2010.
RESULTS: After adjusting for the confounding factors of the study, the NPC cohort had a higher adjusted hazard ratio (HR) for developing ocular complications than the comparison cohort (adjusted HR = 2.786, 95% confidence interval [CI] = 1.805-4.112, P < 0.001). The NPC cohort was associated with a significantly higher risk of developing ocular complications compared with the comparison cohort within 12 and after 24 months of follow-up (P < 0.05). The most common associated ocular complications were optic nerve disorder and retinopathy.
CONCLUSIONS: Patients with NPC might be at higher risk of developing ocular complications after radiotherapy than non-NPC head and neck cancer patients in Taiwan. Either further investigation or routine assessments by ophthalmological physician is recommended.
