TNFSF10 and neoplasm: To further evaluate whether expression patterns of the different TRAIL variants might correlate with histo-pathological variables such as tumour staging, grading, typing, blood vessel invasion, lymphatic vessel invasion or Helicobacter pylori infection and other clinical parameters we performed the Mann–Whitney–U–test for nonparametric data or one-way ANOVA and Bonferroni's Multiple Comparison test to compare TRAIL expression with tumour location.
