Abstract
a total focal dose, space distribution of the dose.
Material and methods. Among PC patients 87% were males and 73.9% were 60 years of age and
older. Local PC (stage Ilia and IUb) was diagnosed in 65.2%. Non-small-cell PC was in 83.8%. Effects of radiotherapy on the survival was analysed in 115 patients. Total focal doses made up 30 Gy
(3.0 Gy/10fractions) to 70 Gy (2.0 Gy/35fractions).
Results. Longer survival was achieved after irradiation with greater dose and modern three-dimentional planning ofconformic radiotherapy. A significant prolongation of the survival was seen in raising
the total focal dose to 50 Gy. There is a correlation between the dose and conformity of the dose distribution. During the study 58.2% patients died.
Conclusion. Assessment of the survival of PC patients given radiotherapy has shown that negative
prognostic factors are the following: PC stage IIIA, IHB and IV, extensive local spread of the tumor,
large primary tumor, involvement of the lymph nodes.
