title: Work in progress: californium-252 brachytherapy plus fractionated irradiation for advanced tonsillar carcinoma.
abstract: A feasibility trial of californium-252 neutron brachytherapy combined with fractionated cobalt-60 therapy for advanced but localized stage T4 tonsillar-retromolar carcinoma is described. Seven patients with primary tumors who were not suitable for conventional radical surgery, chemoradiotherapy and surgery, or surgery plus irradiation were treated. There was complete tumor response in all cases.
