Primary Irradiation, Surgery Or Combined Therapy In Squamous-Cell Carcinoma Of The Larynx - A Comparison Of Treatment Results From 2 Centers

We compared two groups of patients with squamous cell carcinoma of the larynx. Group 1 consisted of 483 patients treated from 1958 through 1978. Primary surgery was selected in 41% pre- or postoperative radiation therapy in 16% and primary radiation therapy in 43%. Group 2 consisted of 247 patients treated from 1978 through 1983. Primary surgery was selected in only 1.6%, pre- or postoperative radiation therapy in 23%, and primary radiation therapy, with surgery in reserve for residual or recurrent carcinoma, in 76%. Although the results were comparable for patients with early stage tumors in the two groups, significantly higher local-regional tumor control rates and corrected survival rates were recorded for patients with advanced tumors in group 2. More patients survived with a cancer-free functional larynx, the surgical salvage rates were higher, the complication rates and the death rates lower in group 2 compared to group 1.
