[ XXXX of the Nasopharynx. Clinical aspects--treatment results--therapeutical improvements (author's transl)].

@entity1 @entity706 @entity189 @entity1606 @entity1953
In the years from 1968-1977 to 44 out of 63 @entity1 with @entity189 of the nasopharynx and to 15 out of 19 @entity1 with @entity706 of the nasopharynx curative radiation therapy was applied. The survival-rates for all @entity189 amount to 63,2% after 3 years, and to 46,5% after 5 years. Half of the @entity1 live up to only 9% of their mean, age- and sex-dependent life expectancy. The prognosis differs with the histological type. @entity1 with @entity1606 had the smallest chance of survival; half of them did not survive. 0.08% of their age-dependent life expectancy. Skeletal infiltration and metastases of the cervical lymph nodes have a bad influence on the therapeutic results. Local recurrences developed in 20% of the @entity1 . Using the examples of 3 @entity1 , who don't belong to the analyzed collective, we shall discuss and optimize the radiotherapeutic management. As a result it is found out, that the megavoltage irradiation therapy (42 MeV X-rays) makes a better dose distribution in tumour-volume than @entity1953 60 rays.
