Two Chemotherapy Regimens Compared With Observation in Treating Patients With Completely Resected Pancreatic Cancer

2014-08-27 03:55:21 | BioPortfolio

Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known which chemotherapy regimen is more effective, or whether chemotherapy is more effective than observation, in treating pancreatic cancer after surgery.

PURPOSE: Phase III trial to compare the effectiveness of two chemotherapy regimens with no further therapy in treating patients who have completely resected pancreatic cancer.

Description

OBJECTIVES:

Primary

- Compare the efficacy of adjuvant gemcitabine vs fluorouracil and leucovorin calcium (vs observation only in patients with ampullary or other pancreatic malignancy), in terms of overall survival, in patients with completely resected pancreatic cancer.

Secondary

- Compare the toxicity of these regimens in these patients.

- Compare the quality of life and 5-year survival of patients treated with these regimens.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to histology (ductal adenocarcinoma vs ampullary or other pancreatic malignancy), resection margin status, and participating country. Patients are randomized to 1 of 2 treatment arms. Randomization for patients with ampullary or other pancreatic malignancy includes an observation arm.

- Arm I: Patients receive leucovorin calcium IV and fluorouracil IV on days 1-5.

- Arm II: Patients receive gemcitabine IV over 30 minutes on days 1, 8, and 15.

- Arm III (patients with ampullary or other pancreatic malignancy only): Patients undergo observation.

Treatment in arms I and II repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity.

Quality of life is assessed at baseline, 3, 6, and 12 months, and then annually for 5 years.

Patients are followed every 3 months.

PROJECTED ACCRUAL: A total of 1,030 patients with pancreatic adenocarcinoma (515 per arms I and II) will be accrued for this study.

Medical and Biotech [MESH] Definitions

The active metabolite of FOLIC ACID. Leucovorin is used principally as its calcium salt as an antidote to folic acid antagonists which block the conversion of folic acid to folinic acid.

A naphthalene derivative and CALCIMIMETIC AGENT that increases the sensitivity of PARATHYROID GLAND calcium-sensing receptors to serum calcium. This action reduces parathyroid hormone secretion and decreases serum calcium in the treatment of PARATHYROID DISEASES.

Agents that increase calcium influx into calcium channels of excitable tissues. This causes vasoconstriction in VASCULAR SMOOTH MUSCLE and/or CARDIAC MUSCLE cells as well as stimulation of insulin release from pancreatic islets. Therefore, tissue-selective calcium agonists have the potential to combat cardiac failure and endocrinological disorders. They have been used primarily in experimental studies in cell and tissue culture.

A phenylethylamine derivative that acts as a calcium antagonist showing hemodynamic effects in patients with acute myocardial infarction.

A 36-amino acid pancreatic hormone that is secreted mainly by endocrine cells found at the periphery of the ISLETS OF LANGERHANS and adjacent to cells containing SOMATOSTATIN and GLUCAGON. Pancreatic polypeptide (PP), when administered peripherally, can suppress gastric secretion, gastric emptying, pancreatic enzyme secretion, and appetite. A lack of pancreatic polypeptide (PP) has been associated with OBESITY in rats and mice.
