Additional Treatment for Isolated Local Pancreatic Cancer Recurrence Using Stereotactic Body Radiation Therapy

A randomized controlled trial, nested within an existing prospective cohort (Dutch Pancreatic Cancer Project; PACAP) according to the 'trials within cohorts' (TwiCs) design in which the effect of additional local ablative therapy compared to current standard of care alone, on survival after recurrence in patients with isolated local pancreatic ductal adenocarcinoma (PDAC) recurrence. The most important secondary endpoint is quality of life. Other secondary endpoints are treatment response, acute and late toxicity, overall survival, progression-free survival, local progression-free survival, distant metastases free survival and reasons for non-eligibility or exclusion.
