However, a negative correlation very close to being significant between TGF-β1 concentrations after the 25 th radiotherapy fraction and maximum grades of late GI toxicity was observed ( p = 0.052).
However, a negative correlation very close to being significant between TGF-β1 concentrations after the 25 th radiotherapy fraction and maximum grades of late GI toxicity was observed ( p = 0.052).
TGF-β1 serum levels after the 25 th fraction were positively correlated with maximum GU toxicity grades, although this correlation was not statistically significant, but showed a tendency towards significance.
