When considering only pancreatic tumour origin, a significantly shorter RFS (HR 2.47, 95% CI 1.02–6.00) and OS (HR 3.47, 95% CI 1.34–8.97) was seen in adjuvant gemcitabine treated cases with tumours displaying high EGFR expression, as compared with low EGFR expression, whereas no survival difference was seen according to high or low EGFR expression among cases not receiving adjuvant gemcitabine. The gene discussed is EGFR; the disease is neoplasm.
