Therapeutic concepts of brachytherapy/megavoltage in sequence for pharyngeal wall cancers. Results of integrated dose therapy.

This is a follow-up report on lateral, posterior oro-, hypopharyngeal wall cancer treatment based on a new therapeutic concept. Ir-192 or I-125 brachytherapy and craniocervical megavoltage irradiation are effective with improved local control and NED (no evidence of disease) survival rates. Local failure rate is 14% and actuarial survival (NED) is 82% at 5 years in 14 patients treated thus far.
