A randomized controlled trial, nested within an existing prospective cohort (Dutch Pancreatic Cancer Project; PACAP) and the United Kingdom (UK) Pancreas Cancer: Observations of Practice and survival; PACOPS) according to the 'trials within cohorts' (TwiCs) design in which the effect of a standardized surveillance, with serial tumor marker testing and routine imaging, compared to current non-standardized practice, on overall survival and quality of life in patients with primary resected PDAC is investigated. The most important secondary endpoint is quality of life. Other secondary endpoints are clinical and radiological patterns of PDAC recurrence, the compliance of patients to our standardized follow-up strategy, the impact of a standardized surveillance on (eligibility for) additional treatment, and the tolerance of additional treatment. The need for this clinical trial is emphasized by the the emergence of more potent local and more effective systemic treatments for PDAC recurrence, leading to a rising interest in early diagnosis by a standardized approach to follow-up with routine imaging and serial serum tumor marker testing.

Overall survival
Timeframe: From date of PDAC resection until date of death from any cause or date of last follow-up, whichever came first, assessed up to 24 months
