RATIONALE: Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs used in chemotherapy, such as fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving radiation therapy in different ways and giving it together with chemotherapy may kill more tumor cells.
PURPOSE: This phase II trial is studying the side effects and how well giving internal radiation therapy and external radiation therapy together with fluorouracil works in treating patients with newly diagnosed or recurrent pancreatic cancer and liver metastases that cannot be removed by surgery.
- Determine tumor response in patients with unresectable, newly diagnosed or recurrent pancreatic cancer and liver metastases treated with selective internal radiotherapy with yttrium Y 90 microspheres, selective external radiotherapy with tomotherapy, and fluoroucacil.
- Determine hepatic and systemic toxicity of this regimen in these patients.
- Determine the efficacy of this regimen, in terms of time to progression and survival, in these patients.
OUTLINE: Patients receive fluorouracil IV continuously on days 1-4. Patients undergo selective internal radiotherapy with yttrium Y 90 microspheres on day 2 and selective external radiotherapy with tomotherapy on day 3.
PROJECTED ACCRUAL: A total of 20 patients will be accrued for this study.

Unstable isotopes of yttrium that decay or disintegrate emitting radiation. Y atoms with atomic weights 82-88 and 90-96 are radioactive yttrium isotopes.
Stable yttrium atoms that have the same atomic number as the element yttrium, but differ in atomic weight. Y-89 is the only naturally occurring stable isotope of yttrium.
An element of the rare earth family of metals. It has the atomic symbol Y, atomic number 39, and atomic weight 88.91. In conjunction with other rare earths, yttrium is used as a phosphor in television receivers and is a component of the yttrium-aluminum garnet (YAG) lasers.
Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.
Organs which might be damaged during exposure to a toxin or to some form of therapy. It most frequently refers to healthy organs located in the radiation field during radiation therapy.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
