[Clinical profile analysis of laryngeal nonsquamous cell malignancies].

OBJECTIVE
To observe clinical characteristics of 15 cases of laryngeal nonsquamous malignancies.


METHOD
The clinical data of 15 patients with laryngeal nonsquamous malignancies were collected. Details about pathology, CT, treatment and follow-up results were carefully taken into account.


RESULT
There were more male patients than females while the sex ratio was 4:1. Supraglottic malignancies accounting for 53.33% seemed to be the most common type. In all the 15 patients, 1 patient gave up other treatment except tracheotomy to relieve laryngeal obstruction. Three patients took radiotherapy and chemotherapy. The rest patients underwent surgical procedure after strict endoscopic, radiologic staging. Radiotherapy and (or) chemotherapy were chosen after operation. The follow-up results show that 1 year survival rate was 79.4% and the 3 year survival rate was 57.8%, 5 year survival rate was 27.5% which was not optimistic.


CONCLUSION
Being a kind of rare type laryngeal nonsquamous malignancies have difference clinical characteristics with laryngeal squamous cell carcinoma. Laryngeal nonsquamous cell carcinoma have much lower 5 year survival rate and are easier to suffer recurrence and metastasis compared with laryngeal squamous cell carcinoma.
