Carbon Ion RT for Locally Advanced Pancreatic Cancer

This is an open-label randomized trial. Subjects will be randomized in a 2:1 ratio to receive carbon ion radiotherapy versus standard care for locally advanced pancreatic cancer. Subjects who receive carbon ion radiotherapy may receive additional chemotherapy afterwards, at the discretion of the treating physicians. Subjects on the control arm are also expected to receive chemotherapy, using a regimen selected by the treating physicians. Subjects on the control arm will not receive upfront radiotherapy but may receive radiotherapy (not carbon ion radiotherapy) if disease progression occurs.
