Carcinogenesis and Diet Restriction

cancer were examined for EGF and TGFa. EGF was detected in only 27.6% of samples while TGFa was present in 88.5%. The median values for TGFa presence were at least 10-fold greater than those of EGF. There was no statistical difference between either TGFa or EGF levels and degree of differentiation of the tumours. There was no statistical difference between stage three and four in relation to concentration of either peptide. Median concentration did not differ significantly among the histological sub-groups.
