Head-and-neck cancer

1.4.2 Head-and-neck cancer

Chemo-embolization with ethylcellulose microspheres of 100-450 μm has been used
in the treatment of maxillary tumours. The role of intra-arterial radioisotope therapy in
the treatment of head-and-neck cancer is just beginning in rabbits, in the work of van
Es et al. [75]. The optimal size of microspheres for treatment of unresectable headand-
neck cancer is still to be established. Van Es et al. suggest that large microspheres
of 40-65 μm should be used for the embolization of these tumours. Other
embolizations in the treatment of head-and-neck cancer have been carried out with
particles of 100-450 μm [76].
