Association Between Chronic Psychological Stress and Disease Course Outcomes in Pancreatic Cancer

This is a prospective, observational cohort study (MIND-PANC) to explore the associations of chronic psychological stress with disease progression, treatment outcomes, and prognosis of pancreatic cancer. Researchers will ask participants to fill out simple questionnaires about their mood, worries, and sleep at the start of the study and at regular follow-up visits. The study will also collect a small blood sample (leftover from routine care) to measure stress-related markers. Investigators hypothesize that pancreatic cancer patients who have higher levels of ongoing psychological stress (such as anxiety, depression, or poor sleep) tend to have shorter survival times, a higher chance of recurrence, and a poorer response to treatment, compared to patients with lower stress levels.
