简要总结
RATIONALE: Vaccines made from gene-modified pancreatic cancer cells may make the body build an immune response to kill tumor cells. Drugs used in chemotherapy, such as fluorouracil, work in different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Giving vaccine therapy together with chemotherapy and radiation therapy after surgery may kill any remaining tumor cells.
PURPOSE: This phase II trial is studying how well giving vaccine therapy together with adjuvant chemoradiotherapy works in treating patients with resected stage I or stage II adenocarcinoma (cancer) of the pancreas.
详细描述
OBJECTIVES:
Primary
- Determine overall and disease-free survival of patients with resected stage I or II adenocarcinoma of the pancreas treated with adjuvant chemoradiotherapy in combination with GVAX pancreatic cancer vaccine.
Secondary
- Correlate specific in vivo parameters of immune response (post-vaccination delayed-type hypersensitivity reactions to autologous tumor, mesothelin-specific T-cell response, and the degree of local eosinophil, macrophage, and T-cell infiltration at the vaccine site) with clinical responses in patients treated with this regimen.
- Determine the toxic effects associated with intradermal injections of this vaccine in these patients.

结局指标
主要结局
Overall Survival
时间窗: Participants were followed for the duration of the study, an average of 2 years
Overall survival in patients treated with adjuvant chemoradiotherapy in sequence with the irradiated allogeneic GM-CSF transfected pancreatic tumor cell lines. Overall survival is defined as time from surgery until death, regardless of cause.
Disease-free Survival
时间窗: Participants were followed for the duration of the study, an average of 2 years
Disease-free Survival in Patients Treated With Adjuvant Chemoradiotherapy in Sequence With the Irradiated Allogeneic GM-CSF Transfected Pancreatic Tumor Cell Lines. DFS is defined as time from surgery until clinical evidence of disease (eg, CT scan) or death due to any cause.
次要结局
- To Further Identify and Characterize Toxicities Associated With Intradermal Injections of the Vaccine That Were Initially Reported in the Phase 1 Trial.(4 years)
- Estimate the Association of Specific in Vivo Parameters of Immune Response With Clinical Responses in Patients Treated With Combination Chemoradiotherapy Together With the Irradiated Allogeneic GM-CSF Transfected Pancreatic Tumor Cell Lines.(Continuous)
