Margin-Intense Combo Therapy in Pts w/Potentially Resectable Pancreatic Cancer

• Status: Terminated
• Trial end date: 2011-02-18
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Stereotactic body radiation therapy may be able to send x-rays directly to the tumor and cause less damage to normal tissue. Drugs used in chemotherapy, such as gemcitabine hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving stereotactic body radiation therapy together with gemcitabine hydrochloride may kill more tumor cells.

PURPOSE: This phase I trial is studying the side effects of stereotactic body radiation therapy when given with or without gemcitabine hydrochloride in treating patients with pancreatic cancer that can be removed by surgery.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Simmons Cancer Center; University of Texas Southwestern Medical Center
• Treatments: Gemcitabine

Criteria

DISEASE CHARACTERISTICS:

• Pathologically confirmed localized adenocarcinoma of the pancreas or distal common bile duct

• Pancreatic ductal adenocarcinoma or peripancreatic cholangiocarcinoma

• Resectable disease, as determined by the Gastrointestinal Cancer Working Group disease-oriented team

• Criteria used to define unresectability will include, but not be limited to, the following:

• Tumor encases > 180 degrees of the circumference of the superior mesenteric artery

• Tumor encases the common hepatic artery with no anatomic option for reconstruction following segmental resection

• Superior mesenteric vein occluded or encased with no option for reconstruction following segmental resection

• Soft tissue infiltration of the retroperitoneum to the left of the superior mesenteric artery

• All malignant disease must be encompassed within a single radiotherapy field

• No metastatic disease

PATIENT CHARACTERISTICS:
