En-bloc irradiation of tumours of the head and neck and their lymphatics. II. Early results and side effects.

The results and side effects of en-bloc irradiation of ear, nose and throat tumours and their lymphatics showed that the technique had been successful in nasopharyngeal carcinoma, but poor in carcinoma of the hypopharynx. Marked early and late radiation side effects were relatively common in high age and with certain tumour sites, whereas no correlation could be demonstrated with total absorbed dose, fractionation, cumulative radiation effect or major surgery.
