abstract = {Introduction: There is some evidence that approximately
$10\%$ of the population show an enhanced intrinsic
radiosensitivity of normal tissue and hence have a higher
risk for developing side-effects during or after
radiotherapy. For that reason there is a need for a fast and
robust test to assess normal tissue response to
radiotherapy. DNA repair deficiency and altered apoptosis
characteristics are discussed as promising markers of
radiosensitivity. The aim of our study was to find out
whether peripheral blood lymphocytes from cancer patients
with strong clinical side effects following radiotherapy as
assessed clinically on the basis of the EPIC questionnaire,
show enhanced rates of in vitro radiation-induced double
strand breaks (dsb), decreased DNA repair capacity and
altered induction of apoptosis when compared to lymphocytes
from patients without side effects and healthy age–matched
donors. Materials and methods: The study included 20
prostate cancer patients without and 20 patients with acute
side-effects during and after radiothrapy, as well as 20
healthy age-matched donors. From each donor, blood samples
were collected, exposed to a radiation dose of 0.5 Gy or 1
Gy of γ –rays and analysed for the following biological
endpoints: the initial level of dsb and the repair kinetics
(γ–H2AX–assay), apoptosis (Annexin V/PI–assay) and
the induction of chromatid–type chromosomal aberrations
(G2–assay). Results: Significant higher chromatid
aberration yield was found between prostate cancer patients
and healthy donors. Eleven patients which suffered because
of acute side-effects after radiotherapy showed an enhanced
aberration level. In addition, an elevated aberration level
was observed also in 11 patients without side-effects after
radiotherapy. No differences were observed between both
patients group in any in vitro assay. Based on the results
of all chosen assays 6 prostate cancer patients were
identified as cellular sensitive, whereof 4 of them were
also clinical sensitive.},
