Chemotherapy and Radiation Therapy Before Surgery Followed by Gemcitabine in Treating Patients With Pancreatic Cancer

• Status: Completed
• Trial end date: 2018-06-15
• Target enrollment: 0
• Participant gender: All

Summary

This pilot clinical trial studies combination chemotherapy and radiation therapy before surgery followed by gemcitabine hydrochloride in treating patients with pancreatic cancer. Drugs used in chemotherapy, such as oxaliplatin, irinotecan hydrochloride, leucovorin calcium, fluorouracil, and gemcitabine hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving combination chemotherapy and radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving chemotherapy after surgery may kill any tumor cells that remain after surgery.

Criteria

Pre-Registration Eligibility Criteria

• Documentation of Disease and Radiographic Staging

• Cytologic or histologic proof of adenocarcinoma of the pancreatic head or uncinate process

• Objective radiographic staging with a) contrast-enhanced, helical thin-cut computed tomography (CT)/magnetic resonance imaging (MRI) scan of the abdomen and b) CT scan/MRI of the chest

• Note: echoendoscopic staging will be permitted as an adjunctive modality, but all stage definitions below will be determined using CT/MRI as outlined below. In the event echoendoscopic stage and CT/MRI stage are discordant, the CT/MRI stage will be used. Significant discordance should be discussed with the study principal investigator (PI) prior to enrollment

• Borderline resectable primary tumor, defined by the presence of any one or more of the following on CT/MRI, and confirmed by central radiographic review:

• An interface between the primary tumor and the superior mesenteric vein or portal vein (SMV-PV) measuring ≥ 180 degrees of the circumference of the vessel wall

• Short-segment occlusion of the SMV-PV with normal vein above and below the level of obstruction that is amenable to resection and venous reconstruction

• Short segment interface (of any degree) between tumor and hepatic artery with normal artery proximal and distal to the interface that is amenable to resection and reconstruction

• An interface between the tumor and superior mesenteric artery (SMA) measuring < 180 degrees of the circumference of the vessel wall

• No potentially resectable disease defined as primary tumors with all of the following:

• An interface between the primary tumor and the superior mesenteric vein or portal vein (SMV-PV) measuring < 180 degrees of the circumference of the vessel wall

• No radiographic interface between the tumor and the (superior mesenteric artery) SMA, hepatic artery or celiac axis

• No radiographic evidence of metastatic disease

• No metastatic disease defined as any one or more of the following:

• Suspicious lymphadenopathy outside the standard surgical field (i.e., aortocaval nodes, distant abdominal nodes)

• Radiographic evidence for metastatic disease in distant organs, such as masses in distant organs or ascites

• No locally advanced and/or unresectable disease clearly defined by any one or more of the following by CT/MRI:

• An interface between the tumor and the SMA measuring ≥ 180 degrees of the circumference of the vessel wall

• No interface between the tumor and the aorta

• Occlusion of the SMV or portal vein without a sufficient cuff of normal vein above and below the level of obstruction with which to perform venous reconstruction

• Long-segment interface (of any degree) between the tumor and the common hepatic artery or its major tributaries with insufficient artery proximal and distal to the interface to perform reconstruction

• No prior chemotherapy or chemoradiation for pancreatic cancer

• No patients with a "currently active" second malignancy other than non-melanoma skin cancers. Patients are not considered to have a "currently active" malignancy if they have completed therapy and are free of disease for ≥ 3 years

• Baseline peripheral sensory neuropathy must be grade < 2

• No patients with known Gilbert's Syndrome or homozygosity for UGT1A1*28 polymorphism

• No history of pulmonary embolism in the past 6 months

• Age ≥ 18 years of age

• Eastern Cooperative Oncology Group (ECOG)/Zubrod performance status 0-1

• Pregnancy/Nursing Status: Non-pregnant and non-breast-feeding. Female participants of child-bearing potential must have a negative urine or serum pregnancy test prior to registration. Perimenopausal participants must be amenorrheic > 12 months to be considered not of childbearing potential.

• Required Pre-Registration Laboratory Values:

• Granulocytes ≥ 2,000/ul

• Hemoglobin > 9 g/dL

• Platelets ≥ 100,000/ul

• Albumin > 3.0 g/dL

• Creatinine ≤1.5 x upper limit of normal (ULN)

Registration Eligibility Criteria

• Confirmation of pre-registration eligibility criteria as described under "Documentation of Disease and Radiographic Staging" by the Alliance Central Radiographic Review

• Required Registration Laboratory Values:

• Bilirubin ≤2 mg/dl

• AST (SGOT) & ALT (SGPT) ≤ 2.5 x ULN
