Treatment of advanced pancreatic cancer: from gemcitabine single agent to combinations and targeted therapy.

The prognosis of advanced pancreatic adenocarcinoma is still poor nowadays. Gemcitabine in monotherapy (30-min infusion) has been the standard of treatment during the last decade, and many clinical trials have failed to demonstrate an improvement in overall survival (OS) with the addition of different drugs to gemcitabine, including cetuximab and bevacizumab. Nevertheless, some modest but interesting advances have been provided by combinations such as gemcitabine-erlotinib, gemcitabine-capecitabine and gemcitabine plus a platinum salt.

Current situation of Panitumumab, Matuzumab, Nimotuzumab and Zalutumumab.

EGFR overexpression usually correlates with a more advanced disease stage, a poorer prognosis and a worse chemotherapy response. EGFR expression increase has been observed in many tumours. For all the aforementioned reasons, EGFR inhibition can be considered an attractive approach in cancer treatment.
