简要总结
RATIONALE: Monoclonal antibodies, such as panitumumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Drugs used in chemotherapy, such as fluorouracil, capecitabine, and gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. External-beam radiation therapy uses high-energy x-rays to kill tumor cells. Panitumumab may also stop the growth of pancreatic cancer by blocking blood flow to the tumor and make tumor cells more sensitive to radiation therapy. Giving panitumumab together with chemotherapy and radiation therapy may kill more tumor cells.
PURPOSE: This phase II trial is studying how well giving panitumumab together with chemotherapy and external-beam radiation therapy works in treating patients with locally advanced pancreatic cancer that cannot be removed by surgery.
详细描述
OBJECTIVES:
Primary
- To evaluate the 1-year survival rate in patients with locally advanced pancreatic cancer treated with panitumumab and continuous infusion fluorouracil administered concurrently with external-beam radiotherapy followed by gemcitabine and panitumumab.
Secondary
- To determine overall survival, time to disease progression, confirmed response rate, duration of response, and time to treatment failure in patients treated with this regimen.
- To determine adverse events in patients treated with this regimen.

结局指标
主要结局
One Year Survival Rate
时间窗: Baseline to 12 months
The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients. Confidence intervals for the true success proportion will be calculated according to the exact binomial method.
次要结局
- Duration of Response(baseline to 2 years)
- Overall Survival(baseline to 2 years)
- Progression Free Survival (PFS)(baseline to 2 years)
- Time to Treatment Failure(baseline to 2 years)
- Confirmed Response Rate(baseline to 2 years)
