Gemcitabine or Combination Chemotherapy Followed by Chemoradiation for Stage IB, II, or III Pancreatic Cancer — PACT-7  

Pancreatic Cancer Clinical Trial

Official title: Randomized Phase II-III Trial of Post-operative Treatment of Pancreatic Adenocarcinoma: Gemcitabine Versus PEFG Followed by Radiochemotherapy With Concomitant Continuous Infusion of 5-fluorouracil

Status Completed

Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy, such as gemcitabine hydrochloride, cisplatin, epirubicin hydrochloride, fluorouracil, and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. It is not yet known whether gemcitabine hydrochloride is more effective when given alone or together with combination chemotherapy and radiation therapy in treating patients with pancreatic cancer.

PURPOSE: This randomized phase II/III trial is studying gemcitabine hydrochloride to see how well it works when given alone or together with combination chemotherapy and radiation therapy in treating patients with stage IB, stage II, or stage III pancreatic cancer.

Clinical Trial Description

OBJECTIVES:

Primary

• Assess the 1-year progression-free survival of patients with stage IB, II, or III adenocarcinoma of the pancreas treated with adjuvant therapy comprising gemcitabine with vs without cisplatin, epirubicin hydrochloride, and fluorouracil followed by chemoradiotherapy with fluorouracil or capecitabine. (Phase II)

• Compare the 2-year overall survival of patients treated with these regimens. (Phase III)

Secondary

• Assess the feasibility and toxicity of these regimens in these patients.

• Assess the impact of these regimens on the quality of life of these patients.

• Assess the pattern of relapse in patients treated with these regimens.

OUTLINE: This is a multicenter study. Patients are stratified according to participating center and radical surgery. Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients receive gemcitabine hydrochloride IV over 1 hour on days 1, 8, and 15. Treatment repeats every 28 days for 3 courses in the absence of disease progression or unacceptable toxicity.

• Arm II: Patients receive cisplatin IV over 1 hour and epirubicin hydrochloride IV on day 1 and gemcitabine hydrochloride IV over 1 hour on days 1 and 8. Patients also receive fluorouracil IV continuously beginning on day 1 or oral capecitabine. Treatment repeats every 28 days for 3 courses in the absence of disease progression or unacceptable toxicity.

Beginning 2-4 weeks after the completion of chemotherapy, patients in both arms undergo radiotherapy 5 days a week for 6 weeks. Patients also receive concurrent fluorouracil IV continuously or oral capecitabine during radiotherapy.

After completion of study treatment, patients are followed up every 3 months. ;
