Filter by:Increasing ablative zone is an essential part to improve technical success and long term outcome in patient treated with radiofrequency ablation (RFA). A combination of dual switching system and separable clustered electrode has been reported to create large ablative zone in preclinical study. Based on preclinical study, the investigators conducted a preliminary study in eligible 60 patients to measure whether this combination (dual switching system and separable clustered electrode) improves technical success rate and local tumor progression rate over a year, in comparison with historical control group.
This is a multicentric randomized parallel group open trial comparing 5-year survival of chemotherapy followed by LT (Group LT+C) versus chemotherapy alone (Group C) in patients with confirmed unresectable liver-only metastases, well controlled by chemotherapy (no progression) and extensively explored by modern imaging techniques. The primary objective of the trial is to validate in a large multicentric cohort of selected patients the possibility to obtain at least 50% 5-years survival with LT combined to chemotherapy compared to around 10% with chemotherapy alone.
The prognosis of peritoneal metastases from colorectal cancer has recently improved with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC). Although outcomes are further improved when early stage peritoneal metastases are treated, adjuvant HIPEC has not yet been thoroughly addressed. This prospective pilot study assessed feasibility, safety and efficacy of HIPEC performed simultaneously with primary curative surgery in colorectal cancer patients with primary tumor-related risk-factors for the development of metachronous peritoneal metastases.
This study will explore the biologic activity of guanabenz in reducing bone turn over in solid tumor patients with bone metastasis. If successful, this repurposing of an already, generic drug could benefit patients faster than manufacturing a novel expensive compound.
Head and neck squamous cell carcinomas (HNSCCs) are mainly caused by tobacco, alcohol consumption and betel nut chewing and the sixth most common cancer in the world. Despite significant advances in the treatment modalities involving surgery, radiotherapy, and concomitant chemoradiotherapy, the 5-year survival rate remained below 50% for the past 30 years. The worse prognosis of these cancers must certainly be linked to the fact that HNSCCs strongly influence the host immune system. During this process, mesenchymal tumor-like cells are highly mobile and enter quickly adjacent structure (intravasation), from where they travel through lymphatic and blood vessels as circulating tumor cells (CTC), which are single cells with malignant potential detected in the peripheral bloodstream and essential for establishing metastasis. Programmed death 1 (PD-1) and its ligand (PD-L1) play pivotal roles in regulating host immune responses. Substantial evidence has demonstrated that PD-L1 can deliver an inhibitory signal to PD-1 expressing T cells, leading to suppression of the immune response by inducing apoptosis, energy, unresponsiveness and functional exhaustion of T cells. However, the inhibitory effects of this pathway on the function of cytotoxic T lymphocytes, the main effector cells in HNSCC patients, are not well defined. In this study aims to solve two main problems: one is to improve and try to optimize current protocols of CTC isolations based on the investigator previous work, which is one of most challenging problems in CTC field to date; the other is to understand the status of immune system in HNSCC patients, especially focusing on PD-1-PD-L1 pathway and its expressions. After series basic experiments of immune cell analysis and conditional adjustment of CTC isolation protocols, the investigator are willing to isolate CTCs and immune cells at a single blood drawing at the same time. A prospective trial will be conducted to elucidate the roles of PD-1 expression lymphocytes and CTC numbers on the clinical outcomes of HNSCC patients.
To investigate whether intraoperative intraportal chemotherapy combined with adjuvant chemotherapy as treatment could improve disease-free survival (DFS) in patients with curative colorectal cancer resection compared with adjuvant chemotherapy alone. This is a prospective, blind (doctors who done outcome measures were masked), multi-center, 2-arm randomized controlled trial.
The purpose of this study is to evaluate the contribution of the imaging to the expression of intégrines αvβ3 for the characterization of the residual masses of non-seminoma tumors at the end of chemotherapy. The investigators hope that the results of this first stage of the clinical trial come to consolidate the preclinical results obtained by the investigators team to characterizing the interest and the strong contribution of the use of a tracer resting on the expression of αvβ3 integrine for the diagnosis of simple necrosed mass at the end of the treatment of a non-seminoma tumor, so allowing to defer a surgery to about 40 % of the patients.
This study is a phase II, prospective, open-label, single arm, single center study of the efficacy and safety of concurrent conventional transarterial chemoembolization (TACE) and sorafenib in patients with hepatocellular carcinoma and extrahepatic metastasis. All of the 55 patients with hepatocellular carcinoma and newly diagnosed extrahepatic (lung, bone, lymph node, adrenal gland) metastasis will be included. On demand conventional TACE will be performed in all the patients after enrollment and can be continued until intrahepatic CR, TACE failure or consent withdrawal. Sorafenib will be started 3-7 days after the first and each subsequent TACE and stopped one day before next TACE and will be continued until sorafenib failure, consent withdrawal or condition worsening by clinical decision. Repeated on-demand TACE and sorafenib should continue until the criteria for treatment discontinuation are met. After initiation of sorafenib combination treatment, patients will be seen and will perform routine examination at week 4 and, after then routine examination will be followed every 6 ± 2 weeks.
The number of intervention performed for metastatic breast cancer has dramatically increased over the past 2 decades. Hepatectomy and pulmonary resection for stage IV colorectal cancer is now considered the standard of care for resectable patients with isolated hepatic and/or pulmonary disease and acceptable performance status. However, the indications for resection / intervention of breast cancer origin metastases are not as clearly defined. The aim of this study to focus on emerging data for the intervention (resection and/or radiofrequency ablation (RFA), transcatheter arterial chemoembolization (TACE), cyberKnife stereotactic radiosurgery) of breast cancer metastatic disease to the lung and liver, with a focus on indications for resection / intervention.
The sentinel lymph node (SLN) procedure is a standard staging technique in several types of cancer. One of the major problems of SLN mapping in colorectal cancer is the lack of an optimal dye and technique for identification of the nodes. In this study the investigators used the Near-Infrared (NIR) dye Indocyanin Green (ICG) to identify nodes with a newly developed NIR laparoscope. The investigators compared two different injection techniques; subserosal and submucosal injection. Patients planned for a laparoscopic resection of a colorectal carcinoma without distant metastases were included. Dye was injected in the subserosa or submucosa of the bowel. Ten minutes after injection the investigators searched for fluorescent nodes with the NIR laparoscope. Fluorescent nodes were harvested and analyzed by the pathologist using H&E and additional immunohistochemistry.
