Abstract:
OBJECTIVE:Study the clinical characteristics, treatment results and prognostic factors of hypopharyngeal carcinoma. MMETHOD: A retrospective analysis was performed of 97 hypopharyngeal cases that were treated in Department of Dtolaryngology of our hospital from January 2008 to December 2012. 93 cases of them are male patients, and 4 cases are female patients. The tumors are originated from pyriform sinus(75 cases), posterior pharyngeal wall (16 cases) and post-cricoid area (6 cases). Of the 97 patients,21 patients were treated with partial hypopharynx resection (21. 6%), 7 were treated with partial laryngectomy+ partial hypopharynx resection (7. 2%), 53 were treated with total laryngectomy+partial hypopharynx resection (54. 6%), 12 were treated with total laryngectomy and total hypopharynx resection, gastric-pharyngeal anastomosis (12. 4%) and 4 were treated with total laryngectomy and total hypopharynx resection, enteric-pharyngeal anastomosis (4. 1%). Sixty-one cases undergo postoperative radiotherapy in Oncology. Use Chi-square test to do enumeration data analysis, the survival rate is calculated with the life table method, survival analysis with Kaplan-Meier method, parallel Log-rank test. Cox regression multivariate analysis model is used to find the factors affecting prognosis.
RESULT:The follow-up rate of this group was 90. 7%. All patients' 1-year survival rate is 76. 0% , 3-year survival rate is 56. 0%, pathological lymph node metastasis rate is 71. 1%, occult lymph node metastasis rate is 19. 6%. Local recurrence rate is 21. 6%. The main reasons of death in patients include : cervical lymph node metastasis in 7 patients (21. 9%), local recurrence in 12 cases (37. 5%), distant metastases in 10 patients (31. 3%) and so on. Univariate analysis showed that tumor size (P<0. 01) and tumor T stage (P<0. 05) have impact on survival prognosis, no risk factors was found with Cox regression multivariate analysis.
CONCLUSION:Hypopharyngeal carcinoma is difficult to be found early, prone to recurrence and metastasis after operation, carefully chosen surgical excision and neck dissection, adjuvant postoperative radiation therapy is the main treatment strategy. Posterior pharyngeal wall carcinoma tend to have higer recurrence and metastasis rate than the other two types of hypopharyngeal caocinom, and treatment would cause much larger injury, so more attention should be paid to this type of hypopharyngeal caocinom.
