Abstract
Research was conducted on the therapeutic results of simultaneous application of radiation and UFT on 17 cases of laryngeal cancer in comparison with the cases to which only radiotherapy was applied. None of the cases were in grave condition. A few cases of side effects were observed such as an absolute decrease of leukocytes and lymph corpuscles, a rise in GOT and GPT, celialgia, intensified mucitis and dermatitis caused by the radiation. Final therapeutic effects still remain to be observed since there have been a relatively small number of cases studied during the short period of observation. However, no unfavorable data have been generated and, in some cases, even favorable progress has been reported in the patients' condition.
