Occult metastases from supraglottic laryngeal carcinoma.

One hundred and sixty-one patients with a supraglottic laryngeal carcinoma and clinically negative neck were studied. All patients had primary surgery and occult cervical node metastases were found in 18% (29/161). Local dissemination of tumour in the epilarynx did not influence the incidence of occult metastases, while the incidence of occult metastases increased with the degree of local spread in the supraglottis excluding the epilarynx.

A comparative study of undifferentiated nasopharyngeal carcinoma treated with radiotherapy or combined treatment with zorubicin-cisplatin and radiotherapy.

Undifferentiated nasopharyngeal carcinoma has been related to the Epstein-Barr virus. These tumors are known to be radiosensitive and chemosensitive. While radiotherapy (RT) allows for a high rate of local control, 80% of all patients die from or with metastatic spread.

[Recurrence around tracheostomies: analysis of risk factors].

302 patients with planocellular larynx carcinoma treated by total laryngectomy during the period from 1975 to 1986 were analyzed. In the examined group of patients significant risk factors in tracheostoma relapse appearance were the next: glottis-subglottis tumor localization and regionally spread tumor. Planned postoperative radiotherapy can significantly reduce the risk of tracheostoma local relapses' appearance.
