RecruitingBehavioural interventionPrehab for Pancreatic Cancer SurgeryThe goal of this clinical study is to test whether a structured prehabilitation program can be successfully used by adults with pancreatic cancer who are receiving chemotherapy before planned surgery. Prehabilitation is a program designed to improve a person's physical fitness, nutrition, and symptom control before surgery. The study's main hypothesis is that patients with pancreatic cancer can take part in and adhere to a multimodal prehabilitation program during chemotherapy, and that doing so may improve physical function, patient experience, and early recovery after surgery.
