Conservation surgery for laryngeal and hypopharyngeal cancer.
The charts of 173 patients treated by conservation laryngectomy and pharyngolaryngectomy were retrospectively reviewed. The patients treated by endoscopic laser resection were excluded of this study. Glottic carcinoma was diagnosed in 101 patients, supraglottic carcinoma in 44 patients, hypopharyngeal carcinoma in 24 patients and oropharyngeal carcinoma in 4 patients. The median follow-up period was 44 months, 84/101 glottic cancer, 34/44 supraglottic cancer, 23/24 hypopharyngeal cancer and 2/4 oropharyngeal cancer were staged as T1 and T2. A voice-sparing external approach was carried on in 20 patients with locally advanced tumor (T3-T4). At time of the last follow-up, 132 patients (77%) were alive when 41 patients (23%) died. Overall survival rates for patients treated for T1- T2 glottic cancer at 3, 5 and 10 years were 90, 90 and 78% respectively. Overall survival rates for patients treated for T1- T2 supralottic cancer at 3, 5 and 10 years were 73, 68 and 48% respectively. Overall survival rates for patients treated for T1- T2 hypopharyngeal cancer at 3 and 5 years were 74 and 37% respectively. The site of the primary tumor (glottic versus supraglottic or hypopharynx) showed significant impact on survival (P = 0.0025)). Regarding survival, T stage and N stage were not found statistically significant.[1]References
