As summarized in Table 5, high cytoplasmic expression levels of survivin (IRS > 4) at the invasion front significantly correlated with limited overall survival in the subgroups of R0-resected patients (p = 0.025) (Figure 2d), of R0-resected patients without distant metastasis (both R0 and M0) (p = 0.029), of patients without metastasis (M0) independent of a residual tumour burden after PDAC resection (p = 0.037), and patients with tumours of the pancreatic tail (p = 0.022) (Figure 2e). This evidence concerns the gene BIRC5 and neoplasm.
