Overview

Patients with PCLM account for the majority of our department's pancreatic cancer cases and often have limited surgical options due to the aggressive nature of their tumors. For those with good performance status (ECOG PS 0-1), NCCN recommends gemcitabine + nab-paclitaxel (AG). Though nimotuzumab combined with gemcitabine improves survival, there remains scarce clinical data regarding its efficacy in conjunction with AG for treating PCLM. This study aims to evaluate the safety and efficacy of incorporating nimotuzumab with AG for PCLM.
