A Study of the Use of the Medtronic Pump and Codman Catheter to Give Chemotherapy to Patients With Colorectal Carcinoma or Cholangiocarcinoma

ABSTRACT: This study is being done to answer the following question: Is the combination of the Medtronic pump and the Codman catheter device a safe alternative to the C3000 Codman pump for delivering chemotherapy directly into the liver of patients with metastatic colorectal cancer or cholangiocarcinoma?

Codman Catheter/Synchromed Pump Hepatic Artery Chemotherapy for Unresectable Colorectal Metastases/Intrahepatic Cholangiocarcinoma

Project description:Due to discontinuation of the Codman C3000 pump, an alternate device is necessary to continue serving patients in need of hepatic arterial infusion chemotherapy. This study aims to test the safety of hepatic artery infusion pump placement, a standard surgical procedure, and intraarterial chemotherapy initiation with the standard medication floxuridine (FUDR), using the Medtronic Synchromed II pump combined with the Codman arterial catheter in patients with unresectable (not removable by surgery) liver metastases from colorectal cancer and unresectable intrahepatic cholangiocarcinoma. This study will determine if complication and pump loss rates will be similar to previously published rates for the Codman system.

Infusion System for Hepatic Cancer

Project description:This is a single-site, open-label continued access study/treatment protocol under a treatment IDE. In addition to treating patients, the primary objective of this study is to assess the safety of using the Medtronic SynchroMed II programmable pump combined with the Intera tapered catheter for hepatic artery infusion (HAI) of a standard chemotherapy (FUDR) drug for adults with a clinical or biopsy-proven diagnosis of colorectal cancer metastatic to the liver or intrahepatic cholangiocarcinoma. After successful implantation, the combined pump and catheter system will be evaluated using a nuclear scan in the postoperative period, which is standard procedure to confirm that the pump is functioning prior to HAI of FUDR. Monitoring for safety will include a record of residual pump volume when it is emptied (every 2-12 weeks depending on whether the pump is being used for chemotherapy infusion) to determine if the pump is still working and surveillance of routine cross-sectional imaging (usually every 2-6 months) for any sign of a pump or catheter problem. Patients will be monitored for the safety of the pump/catheter combination for up to 5 years or pump removal/study withdrawal.

Proteomic analysis of distal cholangiocarcinoma

Project description:Distal cholangiocarcinoma is an aggressive malignancy with a dismal prognosis. There is a lack of diagnostic and prognostic biomarkers. An improved understanding of proteomic changes associated with malignancy and identification of potential biomarkers can help improve the survival of patients. A workflow utilizing discovery mass spectrometry and verification by parallel-reaction monitoring was used to analyze surgically resected formalin-fixed paraffin embedded samples from distal cholangiocarcinoma patients and normal bile ducts in order to identify differentially expressed proteins. 20 tumors and 6 controls were successfully analyzed in the discovery experiment and 16 tumors and 9 controls in the PRM analysis. In the discovery experiment a total of 3057 proteins were identified. 87 proteins were found to be differentially expressed between the conditions (q<0.05 and fold change ≥2 or ≤0.5). 31 proteins were upregulated in the distal cholangiocarcinoma samples as compared to controls and 56 downregulated. Bioinformatic analysis revealed an abundance of the differentially expressed proteins to be associated with the tumor reactive stroma. Parallel-reaction monitoring verified 28 proteins as upregulated and 18 as downregulated. In conclusion several proteins without prior association with cholangiocarcinoma biology were identified and verified as differentially expressed between distal cholangiocarcinoma samples and normal bile ducts. These proteins can be further evaluated to elucidate their biomarker potential and role in distal cholangiocarcinoma carcinogenesis.

Cholangiocarcinoma tissues VS. corresponding normal bile duct tissues

Project description:To identify miRNAs differentially expressed in cholangiocarcinoma,3 human cholangiocarcinoma and their corresponding normal bile duct tissues were obtained from 3 patients after operation with postoperative pathological diagnosed perihilar or distal biliary cholangiocarcinoma miRNAs expression in human cholangiocarcinoma/normal bile duct samples was measured after operation.Three independent experiments were performed using different patients for each experiment.

Changes in cardiac transcription profiles following off-pump coronary revascularization surgery

Project description:To investigate changes in cardiac transcription profiles caused by off-pump cardiac surgery, we collected myocardial samples, prior and after grafting, from patients undergoing off-pump coronary revascularization surgery. The transcriptional profile of the mRNA in these samples was measured with gene array technology. Changes in transcriptional profiles can be correlated with the stress response of heart to off-pump surgery. Keywords: human, cardiac, OPCAB coronary surgery, gene expression.

Transcript profiling of Arabidopsis plasma membrane proton pump mutants

Project description:Plasma membrane proton pump maintains proton electrochemical gradient and provides energy to secondary transporters. Arabidopsis mutant plants with reduced proton pump activity grow normal under ideal growth conditions; however their growth are reduced compared with wildtype plants when placed under the conditions that stress on protonmotive force (high external pH or high external potassium).
