Abstract

CONCLUSION:

The tumor's grade, rather than the tumor's location, was related to the opportunity of preserving laryngeal functions in patients with pyriform sinus cancer. The survival rate decreased significantly with the increase of tumor grade or node grade. Preservation of laryngeal functions is a safe and promising method without compromising the survival rate of patients with pyriform sinus cancer.

OBJECTIVE:

Surgical resection of pyriform sinus carcinoma has a profound influence on the preservation of laryngeal functions. The purpose of this study was to assess the safety and efficacy of the surgical treatment of pyriform sinus carcinoma in the preservation of laryngeal functions without compromising the survival rate.

METHODS:

Two hundred and thirty patients with pyriform sinus cancer had been operated from March 1978 to December 2002. Of them, 158 cases had been operated with the preservation of laryngeal functions and 72 cases had been undergone total laryngectomy. In addition, 216 cases had received adjuvant postoperative radiotherapy. All cases were followed up for 6-12 months (mean 51 ± 26) after surgery. The survival rate was calculated on the basis of Kaplan-Meier analysis, and the factors that influenced the survival rate of patients with and without preservation of laryngeal functions were analyzed with the log-rank test.

RESULTS:

Laryngeal functions were preserved completely (speech, respiration, and deglutition) in 70.9% (112/158) cases, and partially (speech and deglutition) in 29.1% (46/158) cases. The 3- and 5-year survival rates were 75.4% and 59.0%, respectively, for the group with laryngeal function preservation, and 58.6% and 41.5%, respectively, for the group without preservation. There was no statistically significant difference in the survival rate between the two groups within the follow-up period (p > 0.05). Increase in the tumor grade resulted in a proportional decrease of patients with preservation of laryngeal function (p < 0.05). Increase in the tumor grade (p < 0.05) or node grade (p < 0.05) also led to significant decrease in the survival rate. The location of the primary lesions (the lateral wall or medial wall of the pyriform sinus) showed no significant influence on either the opportunity for preserving laryngeal functions (p > 0.05) or survival rate of patients (p > 0.05).
