ObjectiveTo investigate the related factors affecting the prognosis of patients with posterior pharyngeal wall carcinoma (PPWC), so as to provide new ideas for the treatment of this tumor. MethodsClinical data of 109 patients who underwent PPWC surgery in our department from Jan 2009 to Dec 2017 were collected. The survival rate differences between different groups based on patients' gender, retaining laryngeal function, the T stage, N stage, clinical stage and pathological differentiation of tumor, surgical and treatment methods, were analyzed.ResultsThe overall 1year, 3year and 5year survival rates of the 109 patients were 75%, 52% and 38% respectively. The earlier were the N stage and clinical stage of PPWC, the higher survival rate the patients had.ConclusionAs long as appropriate surgical approach is selected to ensure complete resection of PPWC, the laryngeal function of the patient can be preserved and the pharyngeal function can be repaired, which can improve the postoperative quality of life of the PPWC patients.
