Active clinical trials for "Neoplasm Metastasis"

The aim of this study is to analyze cases of human epidermal growth factor receptor (HER) 2-positive metastatic breast cancer (MBC) of the last 10 years at the University Hospital of Zurich to assess the efficacy of the treatment with trastuzumab in HER2-positive MBC and to find out associations between different variables and the outcome. The aim is to find out probable prognostic factors and patterns of disease progression. Prognostic factors could optimize treatment approaches and result in a delay of disease progression.

The primary objective of this study is to correlate the percentage change in apparent diffusion coefficient (ADC) between baseline and early therapy (at day 14) with tumor regression grade (TRG) measured in the surgical resection specimen.

The aim of this study is the characterization from epidemiological, radiomics and molecular point of view of lung metastasis of patients at beginning affected by pancreatic adenocarcinoma (PDAC), which after the resection of primitive tumor have met with initial recurrence of the disease exclusively at the lung level.

In general, brain metastases found after development of neurologic symptoms have poor prognosis. Therefore, the investigators aim to investigate whether regular brain MRI (Magnetic Resonance Imaging) can detect early brain metastases and influence survival through early brain management in HER2-positive and triple negative breast cancer.

Context: In people concerned by serious illness, how to anticipate the aggravation of the disease according to the patient's preferences is a challenging clinical question and an ethical key-issue to improve end-of-life care and quality of dying in France. When end of life decision occurs, many patients can no longer express themselves and advance directives do not seem to be appropriate for many patients despite the current strong incentives to write them, reinforced by the 2016 Claeys Leonetti. The "End-of-Life Discussions" and "Advance care planning" programs developed in the United States have shown a positive impact on the aggressiveness of end-of-life care. The implementation in France of these programs has not yet been consolidated despite a first recommendation for "Planification des soins futurs", published by the French Health Authority(HAS). Inspired by the definition given in the later document, investigators propose the acronym DDA, for the Discussions Dedicated to Anticipate wishes and preferences in the event of Aggravation, defined as the dynamic and evolving process of reflection and communication between the patient, his relatives and healthcare professionals, allowing him to address his preferences and wishes regarding his care and treatment The objective of this observational study is to characterize, in a population of patients with advanced cancer, the profile of those who take up a proposal for Dedicated Discussions on Anticipating preferences of care in the event of Aggravation (DDA) and who engage in the discussion process. Secondary objectives are to evaluate the aggressiveness of end-of-life care in the group of patients who died 1 year after their inclusion, depending on their engagement in DDA occurs and whether or not their preferences are formalized; and evaluate the subjective effects of the DDA with the patient and the investigating professionals, through qualitative approach by a clinical psychologist. Method: investigators designed a mixed, quantitative and qualitative prospective, monocenter methodology to evaluate how patients take up a proposal of DDA. This proposal consists in 2 interviews: the first one is dedicated to the assessment of the patient's wishes in terms of information and participation in decision-making (API questionnaire) and to the assessment of the degree of anxiety and depression (HADS questionnaire) (E1). The second one is conducted 1 to 4 weeks later and consists in offering and initiating DDA (E2). Quantitative outcome evaluated will be: the documentation by a physician in the medical record, of patient's care preferences/values the documentation by the patient of his care preference/values, either by designation of surrogate or by writing advanced directives the usefulness and necessity of this approach, and the anxiety it generated, as perceived by the patient The qualitative assessment will be based on data collected during E1 and E2, and for 20 patients, during a clinical interview with a psychologist dedicated to collecting the patient's impressions of previous interviews. Thanks to this study investigators expect to gather some data on the desire and feelings of cancer patients to engage in a DDA process and possibly formalize their end-of-life preferences, the impact of DDAs on care pathway indicators and the psychological effect for the patient with severe disease to project himself in advance into aggravation. These expected results will provide a better understanding of the process of anticipating end-of-life situations, which is needed to improve quality of care and end-of-life conditions.

After stereotactic radiosurgery (SRS) of brain metastases, patients undergo a standard brain magnetic resonance imaging (MRI) to assess treatment response 12 weeks after completion of treatment. The interpretation of this standard MRI can sometimes be challenging as it can be difficult to differentiate tumour getting bigger/returning (progression/recurrence) from expected radiotherapy treatment-related changes known as radionecrosis. This study is a pilot brain imaging study that is investigating if readily available forms of imaging such as contrast-clearance analysis MRI (also known as TRAMs) and/or 18 Fluoromethyl-choline positron emission tomography/computerised tomography (18F-choline PET/CT) are equivalent to multi-parametric MRI in their ability to differentiate tumour from radionecrosis. Multi-parametric MRI has the most evidence for its ability to discriminate tumour from radionecrosis but is resource intensive and not routinely available in most centres.

Through multi-center randomized controlled trial studies on preemptive surgical intervention in patients with chronic kidney disease (CKD) - secondary hyperparathyroidism (SHPT), to precisely evaluate the safety and effectiveness during perioperative period, and the long-term outcomes by 1-year follow-up. The follow-ups include the evaluation of the overall quality of life, calcium and phosphorus metabolism, hyperparathyroidism level, vitamin D metabolism, bone mineral density, soft tissue and vascular calcification.

The aim of this study is to reduce the length of stay after liver surgery by taking account of objective quantitative clinical variables, subjective qualitative clinical variables and non clinical variables.

The purpose of this study is to assess short and long term outcomes after radiofrequency ablation (RFA) combined with chemotherapy for pulmonary malignancies in patients who are not candidates for surgical resection. This study will evaluate the efficacy of RFA combined with chemotherapy for the treatment of lung tumors by assessing its impact on local tumor control, progression free survival, overall survival, dyspnea score and quality of life (QOL).

The purpose of this study is to determine whether the PILP-kit can be safely used, within specific performance parameters, to isolate and perfuse the liver with a chemotherapeutic drug for the treatment of patients with unresectable liver metastases.
