The treatment of T3N0M0 glottic squamous cell carcinoma / 中国耳鼻咽喉头颈外科

ABSTRACT

OBJECTIVE To assess the outcomesof three different therapeutic approaches for the treatment of T3N0M0(stage Ⅲ) glottic squamous cell carcinoma. METHODS Sixty-five cases of T3N0M0 glottic squamous cell carcinoma treated with curative intent by three different modalities include vertical hemilaryngectomy(VHL,n=21),total laryngectomy(TL,n=31)and radiotherapy(RT,n=13) were reviewed retrospectively. The survival rate,recurrence rate at the primary lesion site and jugular lymph node, and laryngeal preservation was compared among three methods. RESULTS There was no significant difference in the overall survival rates(Cox proportion hazard model) and recurrence rates at the primary lesion site or jugular lymph node among the three methods. Laryngeal function was preserved in 100% of the cases in the VHL and RT groups after initial treatment. CONCLUSION The three treatment modalities had statistically similar survival and recurrence rates. Patients treated with VHL and RT had a higher rate of laryngeal preservation compared to that of TL, hence VHL or RT is a valid alternative to TL in treating selected patients with T3N0M0 glottic squamous cell carcinoma.
