Plain English Summary
Background and study aims
Pancreatic cancer is cancer that starts in the pancreas (a gland that produces digestive juices and hormones). It can be treated with surgery to remove the cancer, followed by chemotherapy, where anti-cancer medicines are used to kill any cancerous cells left behind (adjuvant chemotherapy). This lowers the risk of the cancer coming back and prolongs patient survival, but its benefit is limited. Chemoradioimmunotherapy is a combination of chemotherapy, radiotherapy (which uses high energy rays to kill cancer cells) and immunotherapy (treatment that re-awakens the immune system so it can fight cancer). The aim of this study is to assess the effect of chemoradioimmunotherapy compared with adjuvant chemotherapy alone.
Who can participate?
Patients aged over 18 who have undergone surgery to completely remove pancreatic cancer within the last 12 weeks
What does the study involve?
Participants are randomly allocated to be treated with either chemoradioimmunotherapy (fluorouracil, cisplatin and interferon alfa-2b plus radiotherapy followed by two cycles of fluorouracil), or six cycles of adjuvant chemotherapy (fluorouracil). Patient survival is assessed two years later.
What are the possible benefits and risks of participating?
There will be no immediate direct benefit to those taking part, but there should be benefits to future patients with pancreatic cancer because the results of the study are likely to influence treatment. The main risk of the study will be side effects of the treatment. The participants will be closely monitored on a daily/weekly basis.
Where is the study run from?
The study has been set up by the University of Heidelberg in collaboration with various clinics in Germany and the Department of General and Oncological Surgery, Ospedale Mauriziano "Umberto I", Torino, Italy.
When is the study starting and how long is it expected to run for?
August 2004 to July 2006

Intervention
Patients in study arm A will be treated with:
1. 200 mg/m^2/day 5-Fluorouracil (5-FU) by continuous intravenous (IV) infusion on days 1 - 38
2. 30 mg/m^2 Cisplatin IV over 60 minutes (with pre- and post-hydration) on days 1, 8, 15, 22, 29, 36 (6 doses)
3. 3 million units subcutaneous (SC) Interferon alpha-2b days 1 - 38 (17 total doses)
External beam radiation is to be given concurrently with chemotherapy with a total dose of 50.4 Gy in 28 fractions over 5.5 weeks (1.8 Gy/day).
In study arm A the patients receive post-chemoradiation 5-FU infusions of 200/mg/m^2/day by continuous intravenous infusion on days 64 - 101 and 120 - 161.
Patients in study arm B will be treated with 20 mg/m^2 intravenous bolus injection of Folinic acid, D-L form, followed by 425 mg/m^2/day intravenous bolus injection of 5-FU given on 5 consecutive days every 28 days for 6 cycles i.e. 24 weeks.
