A Study of Gemcitabine/Nab-paclitaxel and Radiation Therapy Followed by Surgery in Patients With Advanced Pancreatic Cancer

Gemcitabine and nab-paclitaxel are chemotherapy drugs that are currently approved by Health Canada for use in combination for the treatment of pancreatic cancer. However, the combination of gemcitabine and nab-paclitaxel as a neoadjuvant treatment prior to gemcitabine and radiation is experimental. Surgery to remove or reconstruct the major artery is also experimental.
