Due to small numbers of cases with recurrence, no significant correlation was found between the total immune staining scores in primary tumors and tumor tissue from local recurrence, but a tendency toward positive correlation was seen for uPAR (spearman correlation = 0.395; p = 0.510), EpCAM (spearman correlation = 0.111, p = 0.834), and PARP-1 (spearman correlation = 0.064, p = 0.905). Here, PLAUR is linked to neoplasm.
