Ontology highlight
ABSTRACT: RATIONALE: Diagnostic procedures, such as fludeoxyglucose F 18-PET imaging, may be effective in detecting residual disease after radiofrequency ablation of liver metastases in patients with colorectal cancer.
PURPOSE: This clinical trial is studying fludeoxyglucose F 18-PET imaging to see how well it works for early detection of residual disease in patients undergoing radiofrequency ablation of liver metastases from colorectal cancer.

Project description:RATIONALE: Diagnostic imaging procedures, such as fludeoxyglucose F 18 PET, may be effective in detecting cancer or recurrence of cancer, or premalignant polyps.
PURPOSE: This clinical trial is studying fludeoxyglucose F 18-PET imaging to see how well it works in determining protein and gene expression signatures in patients with premalignant polyps or colon cancer.
Project description:Gene expression profiling of disseminated tumor cells in lung, lung metastatses and residual tumor cells in the MMTV-PyMT breast cancer model. Profiling gene expression change between disseminated tumor cells, lung metastases and residual tumor cells from the MMTV-PyMT breast cancer model.
Project description:To investigate the clinical effect of radiofrequency ablation on colorectal cancer liver metastases with different KRAS gene status
Project description:We did the transcriptomic profiling of HCC1954 Parental(Pa), synchronous (S-BM), latent residual (Lat) or metachronous (M-BM) brain metastases cells
Project description:Incomplete thermal ablation may induce invasiveness of hepatocellur carcinoma, however, the mechasim is not fully understood. Here, we investigated whether activated hepatic stellate cells would accelerate the progression of residual HCC after sublethal heat treatment via the secretion of POSTN. We used microarrays to detail the global programme of up-regulated genes of residual HCC cells induced by POSTN.
Project description:We collected 5 pairs of HCC tissues with incomplete radiofrequency ablation before and during surgery, and a total of 10 samples were sequenced for proteome analysis. It was found that some genes had some changes in protein expression due to the thermal ablation effect caused by radiofrequency ablation.
Project description:Irreversible electroporation (IRE) is a new, minimal-invasive image-guided treatment method for tumors not amenable for surgical resection or thermal ablation, due to vicinity near vital structures such as vessels and bile ducts. With IRE, multiple electrical pulses are applied to tumorous tissue. These pulses alter the existing transmembrane potential of the cell membranes, and create ‘nanopores’, after which the cell dies through loss of homeastasis.
The purpose of this study is to investigate the efficacy of percutaneous and open IRE in the treatment of patients with colorectal liver metastases (CRLM) that are unsuitable for resection or thermal ablation due to vicinity to vulnerable structures such as vessels and bile ducts. Other objectives are safety, feasibility (technical success) and imaging characteristics on follow-up (PET-)CT and PET-MRI and the value of these imaging modalities in dianosing local site recurrence (LSR) or residual disease (RD).
29 patients with histologically confirmed colorectal carcinoma who present with unresectable and not thermally ablative CRLM< 3.5cm suitable for IRE will undergo percutaneous or open irreversible electroporation of the tumor using CT and ultrasound guidance. All (serious) adverse events are registered. One day post-IRE MRI is performed to assess technical success. Follow-up will consist of frequent (PET-)CT and (PET-)MRI scanning to localize residual or recurrent disease. Overall technique effectiveness is determined 1 year after treatment.
The investigators hypothesize that IRE for central CRLM will lead to good tumor control without causing severe complications.
Project description:The hypothesis is that radiofrequency ablation combined or not with resection may allow a local control (the liver) in patients suffering from unresectable colorectal liver metastases. Patients may have benefit or not from a preoperative (neoadjuvant) chemotherapy.
Project description:RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread by blocking blood flow. Others find tumor cells and help kill them or carry tumor-killing substances to them. Radiofrequency ablation uses high-frequency electric current to kill tumor cells. It is not yet known if chemotherapy is more effective with or without radiofrequency ablation in treating liver metastases.
PURPOSE: This randomized phase II trial is studying combination chemotherapy, bevacizumab, and radiofrequency ablation to see how well they work compared to combination chemotherapy and bevacizumab alone in treating unresectable liver metastases in patients with colorectal cancer.
Project description:The purpose of this study is to determine whether combining of radiofrequency ablation (RFA) and cytokine-induced killer cells (CIK) transfusion can prolong survival of patients with colorectal cancer liver metastases (CRCLM).
