Factors influencing the incidence of sinusitis in nasopharyngeal carcinoma patients after intensity-modulated radiation therapy.

The aim of the study was to investigate the incidence of sinusitis in nasopharyngeal carcinoma (NPC) patients before and after intensity-modulated radiation therapy (IMRT) and to analyze factors associated with the incidence of sinusitis following IMRT. We retrospectively analyzed 283 NPC patients who received IMRT in our hospital from March 2009 to May 2011. The diagnostic criteria for sinusitis are based on computed tomography (CT) or magnetic resonance imaging (MRI) findings.

Prognostic value of expression of EGFR and nm23 for locoregionally advanced nasopharyngeal carcinoma.

The purpose of this study was to evaluate the prognostic value of expression of EGFR and nm23 in patients with advanced-stage nasopharyngeal carcinoma (NPC). The study population comprised 127 patients with stage III-IVa NPC with sufficient pretreatment tumor biopsy specimens from 2003 to 2004 and clinical follow-up data. The expression of EGFR and nm23 was detected by immunohistochemistry.
