[Laryngeal function-sparing surgery for pyriform sinus cancer].

OBJECTIVE

To evaluate the oncologic effect of laryngeal function-sparing surgery for the patients with pyriform sinus carcinoma.

METHODS

A retrospective analysis was performed. Forty-four patients with pyriform sinus cancer who underwent operations were included. There were 10 patients in T1, 14 in T2, 18 in T3 and 2 in T4 categories. 42 patients received preoperative radiation and 2 cases, post-operative radiation. Surgery for the local lesions: 36 patients underwent pyriform sinusectomy and 8, partial laryngectomy and pyriform sinusectomy.

RESULTS

Five year survival rate is 50% for the whole series, 80% for stage I, 71.4% for stage II, 52.9% for stage III, 26.7% for stage IV and 45% for all T3 + T4 patients. Local control rate is 81.8% for all patients and 75% for T3, T4 patients.

CONCLUSION

For selected pyriform sinus cancer patient a conservative laryngeal surgery is warranted with the combination of preoperative radiative therapy.
