Abstrakt: Background: The purpose of this study was to report the risk of pharyngoesophageal stricture after treatment for head and neck cancer.
Methods: Human studies on radiation therapy with or without chemotherapy for head and neck cancer published in peer-reviewed journals with assessment of pharyngoesophageal stricture with barium swallow or endoscopy were included.
Results: A total of 4727 patients from 26 studies treated between 1989 and 2008 were eligible for analysis. The reported overall risk of stricture was 7.2%. The risks of pharyngoesophageal stricture in both conventional and intensity-modulated radiation therapy (IMRT) studies were 5.7% and 16.7%, respectively (p < .001). Use of concurrent (p < .001) and taxane (p = .01) chemotherapy was associated with the IMRT technique. Prospective studies reported a 3.3-fold increased risk of stricture compared with that of retrospective studies (odds ratio: 3.3; 95% confidence interval: 2.3-4.8; p < .001).
Conclusions: Pharyngoesophageal stricture after IMRT and chemotherapy treatment for head and neck cancer is not uncommon. Videofluoroscopic swallow study should be performed prospectively to evaluate swallowing function.
