We analysed for possible correlations between tumour pathology parameters and progression‐free survival based on the percentage of positive ALDH1A3, tPA, uPA, and PAI‐2 cells, or the combination of ALDH1A3 with tPA or uPA, or ALDH1A3 combined with PAI‐2 negative cells. Here, SERPINB2 is linked to neoplasm.
