The sentences
Thus, no variations were found in colorectal carcinoma for the 35 tumours tested but one of the 25 gastric cancers tested was positive for p53 on the frozen material and negative on the paraffin section. The relationship between p53 expression and several clin- ico-pathological criteria related to prognosis is shown in Table II for gastric and Table III for colorectal carcinoma. There is a highly significant correlation between p53 expres- sion and tumour stage in gastric and colorectal carcinoma.
