Total laryngectomy and postoperative radiotherapy for T4 laryngeal cancer: A 14-year review.

摘要

OBJECTIVE: The most appropriate treatment of locally advanced carcinoma of the larynx remains to be ascertained. Management of T4 laryngeal cancer patients with postoperative radiotherapy after total laryngectomy is generally advocated and not often debated. However, the effects of this combined treatment approach are poorly documented. We reviewed the oncologic outcome and long-term survival of individuals treated by total laryngectomy and postoperative radiotherapy (TLPR) for T4 carcinoma of the larynx. METHODS: Twenty-eight patients with a pathologic diagnosis of T4 laryngeal cancer treated by TLPR during a 14-year period were studied retrospectively. Median follow-up from treatment until the end of observation was 36 months (range 6 to 123 months). RESULTS: The overall actuarial and disease-free survival rates at 7 years were 43% and 30%, respectively. Local recurrence, regional relapse, and distant metastasis developed in 4%, 4%, and 7% of the cases, respectively. Later esophageal stricture, dental caries, or carotid artery disease in 3 patients (11%) was successfully managed. Multivariate analysis showed patient age, bilateral true vocal cord-anterior commissure involvement by laryngeal cancer (horse-shoe lesion), and any type of treatment failure to be the most predictive variables affecting prognosis. CONCLUSION: Long-term disease control and survival is achievable by TLPR with minimal late toxicity in patients with T4 carcinoma of the larynx.
