The median survival months for patients with pancreatic cancer and negative for tissue expression of ErbB2 was 39.00 (11.79–66.21) months; however, in the case of patients with low-medium expression, it was 16.00 (14.21–17.79) months, falling to 6.00 (4.43–7.56) months for patients with high expression (Figure 3). The gene discussed is ERBB2; the disease is pancreatic neoplasm.
