However, there were no statistically significant relationships between HSF1 expression and other clinicopathological variables, such as gender (P = 0.459), age (P = 0.814), tumour location (P = 0.341), histological type (P = 0.483), differentiation (P = 0.225) and CEA (P = 0.709). This evidence concerns the gene CEACAM5 and neoplasm.
