摘要:
Background. Lymphoepithelioma-like carcinoma (LELC) in the salivary glands is a rare but unique malignancy. Methods. Sixty-nine patients with salivary gland LELC with long-term follow-up were reviewed for this study. Results. There were 52 cases in the parotid gland and 17 cases in the submandibular gland. All patients underwent complete tumor excision, 41 underwent neck dissection, and 39 received postoperative radiotherapy. The 5-year, 10-year, and 15-year overall survival (OS) rates were 90%, 75%, and 54%, respectively. Patients with higher neutrophil/lymphocyte ratio (NLR >= 4.0) and advanced stage (stage III and IV) had significantly poorer OS. Patients who received postoperative radiotherapy had significantly better relapse-free survival (RFS). In multivariate analysis, stage, NLR, and neck dissection were associated independently with OS, whereas stage and postoperative radiotherapy were associated independently with RFS. Conclusion. Salivary gland LELC is a rare malignancy with a better prognosis that partially attributes to surgery with neck dissection and postoperative radiotherapy. Preoperative NLR is an independent prognostic factor. (C) 2014 Wiley Periodicals, Inc.
