Filter by:This study evaluates the incidence of cardiac arrhythmias during the perioperative period in patients undergoing open kidney cancer surgery in the lateral position. All the participants will be randomly allocated to receive general (Group G) or combined epidural/general anaesthesia (Group G/E). The anaesthetic technique is standardized. The Holter monitor will be applied at the evening before the surgery, tracing continuously for a period of 24 hours (7PM-7PM)
Postoperative cognitive dysfunction (POCD) and postoperative delirium occurs mainly in aged patients. POCD and POD may increase the mortality and morbidity. However, the mechanism of POCD is not clear yet and no effective therapy method was proved. According to previous study, the neuroinflammation is the main reason both for POCD and POD. Minocycline is a tetracycline derivative. Due to it's lipophilic structure, it is easy to pass through blood brain barrier and attenuate neuroinflammation. It's neuroprotective effects has been proven in many experimental animal models such as Alzheimer's disease, Huntington's disease and Parkinson's syndrome. In present study, the investigators hypothesized that minocycline would attenuate the incidence of POCD and POD in the aged patients.
The rise of oral targeted therapies favors outpatient care of cancer patients but exposes them to new risks compared to the injectable chemotherapy in the hospital: non-adherence to treatment, inappropriate management of side effects and interactions with other co-prescribed drugs. The clinical consequences (reduced efficacy and potentialized toxicity) are all the more important that ambulatory monitoring of treatments prescribed at the hospital remains underdeveloped due to default of coordination between these two settings. Adverse drug reactions are a major concern, as such, and because they involve prescription changes (dose reduction, treatment interruption). This results in a decrease in the dose taken and a risk of loss of efficacy. In the context of metastatic renal cell carcinoma, the risk of iatrogenicity is even higher because the oral targeted therapies available in this indication have a safety profile marked by potentially serious toxicities (hematologic and cardiac toxicity) or are known to reduce the treatment adherence (digestive and skin toxicities). In addition, these molecules are metabolized by the CYP3A4 hepatic cytochrome, which leads to avoid associating them with drugs inducing and / or inhibiting the CYP3A4, because of the risk of toxicity and / or loss of efficacy. The investigators propose to assess a program set up to secure drug taking by enhancing self-management of side effects and control of drug interactions by the patient. This program includes pharmaceutical visits and involves inpatient and outpatient (doctor, referent pharmacist and liberal nurse) professionals. The hypothesis of the study is that the PRISM care program will improve self-management of side effects by the patient, resulting in a relative dose intensity of oral chemotherapy improved compared to usual care.
Irreversible Electroporation (IRE) is an emerging technique delivering electrical pulses to ablate tissue, with the theoretical advantage to overcome the main shortcomings of conventional thermal ablation. Recent short-term research showed that IRE for the ablation of renal masses is a safe and feasible treatment option. In an ablate and resect design, histopathological analysis 4 weeks after radical nephrectomy demonstrated that IRE targeted renal tumors were completely covered by ablation zone. In order to develop a validated long-term IRE follow-up study, it is essential to obtain clinical confirmation of the efficacy of this novel technology. Additionally, follow-up after IRE ablation obliges verification of a suitable imaging modality. The objectives of this study are the clinical efficacy and safety of IRE ablation of renal masses and to evaluate the use of cross-sectional imaging modalities in the follow-up after IRE in renal tumours. This is a prospective, human, in-vivo study among 20 patients presenting with solid enhancing SRM on cross sectional imaging suspect for renal cell carcinoma (RCC). Preoperatively, imaging is required through Magnetic Resonance Imaging (MRI), Contrast-enhanced ultrasound (CEUS) and contrast-enhanced Computed Tomography (CT). Furthermore, serum creatinine levels and VAS scores are obtained. A biopsy of the SRM will be performed in preoperative setting. IRE ablation will be performed using CT-guidance and ablation success will be measured directly after the ablation through contrast-enhanced CT. Device related adverse events (AE) will be registered using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 guideline. One week post ablation only CEUS and MRI will be performed to limit exposure to ionizing radiation. At 3 months, 6 months and 12 months post ablation CEUS, MRI and CT will be performed. Additionally, at these time points serum creatinine levels and VAS scores will be obtained, and quality of life will be assessed through SF-36 questionnaires. Residual and recurrent disease will be assessed through tissue enhancement on cross sectional imaging.
The main objective of study is to describe the priorities of elderly patients (70 years and over) undergoing a first medical treatment for cancer, at initiation of treatment and after 3 months of treatment. The main criterion is a prioritization of 4 items per patient from a list of 8 expectations regarding the objectives of their treatment: treatment efficacy, life expectancy, autonomy, daily activities, social activities, heaviness of treatment, toxicity, economics.
Zero ischemia laparoscopic radio frequency ablation assisted tumor enucleation has been proved to enable tumor excision with relatively better renal function preservation comparing with conventional laparoscopic partial nephrectomy for T1a renal cell carcinoma (RCC) in a randomized clinical trial in single center. The investigators want to explore this technique to T1 RCC patients in randomized clinical trial in multiple centers.
Advanced renal cell carcinoma is invariably fatal, with a life expectancy of 2-3 years since diagnosis. Sunitinib is the standard first-line treatment for this condition, but it is associated to multiple side effects, with fatigue being reported in 51-63% of patients. As sunitinib-induced fatigue is likely to be mediated by inhibition of AMPk function, the investigators hypothesize that isoquercetin, which is hydrolyzed in vivo to quercetin, a known AMPk activator, is able to reduce fatigue in kidney cancer patients taking sunitinib.
Retrospective studies indicate that active surveillance for clinically localized, small renal masses (cT1a, <=4cm) is safe. It is our hypothesis that active surveillance is safe and efficacious when compared prospectively to patients undergoing immediate intervention for their small renal mass.
Background: Electroporation or electropermeabilisation is a novel technique with the potential to overcome the main disadvantages of thermal ablation. It utilizes electric pulses, traveling between two or more electrodes, to create 'nanopores' in the cell membrane. If the applied current reaches a certain threshold these 'nanopores' become permanent resulting in cell death. The use of electric current means that IRE is not susceptible to 'thermal sink' leading to consistent ablation results. IRE ablation targets the cell membrane, sparing tissue architecture and minimizing damage to blood vessels, nerves and the renal collecting system. The first in human studies have proven the safety of IRE for the ablation of small renal masses. However the efficacy of IRE through histopathological examination of an ablated renal tumour has not yet been studied, compromising the correct and scientific evaluation of this new technology. Primary Objectives: - To determine the efficacy of IRE ablation of renal masses , measured by histopathologic examination of the targeted tumour. - To determine the safety of IRE ablation of renal masses, by evaluating device and procedural adverse events. Secondary Objectives: - To evaluate the efficacy of MRI in the imaging of ablation success, extend of the ablation zone, one and four weeks post IRE ablation. - To evaluate the efficacy of CEUS in the imaging of ablation success, extend of the ablation zone, one and four weeks post IRE ablation. Population: 10 patients, age ≥ 18 years, presenting with a solid enhancing mass, who are candidates for radical nephrectomy. Intervention: Eligible patients will receive IRE ablation of their renal mass 4 weeks prior to radical nephrectomy. Follow-up at one and four weeks post IRE will be performed using MRI and CEUS imaging. After radical nephrectomy histopathological examination will be performed to evaluate IRE ablation success.
