Objetives: The objetive of the present study is to value the
results obtained in the treatment of 28 patients a prospective
group, affected of upper lip carcinoma treated through external
molds of high dose rate brachytherapy.
Design of the study: A total of 28 patients ffected of lip carcinoma
were treated through superficial ready ' made molds and
high dose rate brachytherapy. The dose of radiation given was
6.000 to 6.500 cGy in 33 to 36 fractions of 180 cGy on tumors
up to 4 centimeters of diameter. On the big tumors the dose
given was 7.500 to 8.000 cGy in 43 to 46 fractions. The patients
were followed every 3 months, evaluating in each visit the local
control, regional and at distance of the tumor, the existence of
complications or sequels and the aesthetic result obtained.
Results: All the patients completed the foreseen treatment. All
the cases had complete remission of the tumor. During the period
of pursuit local relapses were not detected neither regional or
at distance. Patients did not present inmediate or late complications
during the treatment. In the observations made 6 and
12 months after the treatment 27/28 patients had excellent or
good aesthetic results.
Conclusions: Because of the high control of the tumor,good
tolerance to therapy, absence of complications and reverts,easy
employment of molds, accuracy in positioning the source in the
daily repetition of the treatment and the security that offers for
radioprotection,we conclude that this therapy will probably be
of habitual use the next years.Dado los diferentes métodos terapéuticos para el cáncer de
labio, el objetivo del presente estudio es valorar los resultados
obtenidos en un grupo prospectivo de 28 pacientes afectos de
carcinoma de labio tratados mediante moldes externos de braquiterapia
de alta tasa de dosis. Tanto por la remisión completa
que ocurrió en todos los casos, la buena tolerancia a la terapia,
la ausencia de complicaciones y de recurrencias, la facilidad
de empleo de los moldes, la precisión en el posicionamiento de
la fuente en la repetición diaria del tratamiento y la seguridad
que ofrece en cuanto a radioprotección, concluímos que esta
terapéutica probablemente se convierta en la de uso habitual
en los próximos años.
