Weitere Verlaufsbeobachtungen nach CO 2 -Laserbehandlung von Larynxmalignomen

Based on the criteria of long survival and recurrence rates after an observation period of maximally 4 years, the recent results of endolaryngeal laser resection of malignomas of stage Tis to stage T2 are reported. Recurrence rates after laser resection of T1 tumors as well as many cases of T2 tumors seem to be comparable to those after standard surgical treatment or radiotherapy. In Tis tumors, treatment by evaporation of pathological tissue can be applied only, if by previous biopsy and histological examination an infiltrative tumor growth can be safely excluded; in all other cases additional resection is necessary.
