[Material and methods] We compared 24 cases of partial laryngectomy (PL) and 14 case of partial laryngo-pharyngectomy (PPL) that we performed from 1993 to 2005 with 17 cases of superselective arterial infusion and concomitant radiotherapy (iaCRT) in the same period. In addition, for 20 hypopharyngeal cancer patients who received radiotherapy from 1999 to 2003 we examined whether laryngeal preservation surgery was possible.
[Results] As for the cause-specific five-year survival rate by Kaplan-Meier's method for laryngeal cancer, PL cases were 81.3% and iaCRT cases were 87.5% (N.S.). As for the survival rate for hypopharyngeal cancer, PPL cases were 39.5% and iaCRT cases were 55.6% (N.S.). For the hypopharyngeal cancer patients who received radiotherapy, it was judged to be passible in 12 of 20 cases laryngeal preservation surgery.
[Conclusions] Patients who have received radiotherapy may be suitable for laryngeal preservation surgery for laryngeal cancer and hypopharyngeal cancer.
