Filter by:Because Primary Central Nervous System Lymphoma (PCNSL) are mainly diffuse large B-cell lymphoma of the activated B cells (ABC) type, the investigators hypothesize that the synergy of lenalidomide with rituximab shown in systemic non-Hodgkin's lymphoma (NHL) could be observed in PCNSL. This study will assess the efficiency of the the combination of lenalidomide and rituximab in relapsed/refractory PCNSL, and the efficiency of a maintenance treatment with lenalidomide alone in maintaining the response.
After a curative treatment by radiotherapy for localized prostate cancer, between 20% and 50% of patients may have a biological relapse as a progressive re -rise of PSA. After prostate brachytherapy with low flow, this rate is between 2% and 6%. Depending on risk factors initially present, some patients will have a micro metastatic disease at the time of re-rise, but others will have a true local recurrence purely intra-prostate. Local recurrence after radiotherapy is associated with a high incidence of distant metastatic relapse and poor overall survival. For these reasons, the possibility of offering a local treatment for this selected population of patients can have a major therapeutic interest and allow changing a situation often considered palliative to the possibility of a second curative treatment. Currently, there is no consensus regarding the optimal management of patients with purely local recurrence after prostate irradiation at first intention. When an external radiotherapy or brachytherapy is performed as first choice in a patient with prostate cancer, several remedial treatments have been proposed, with controversial results the decision-making for clinicians and for difficult patients. These main therapeutic options remedial (surgery, cryotherapy and brachytherapy) have the potential for complications such as rectal injury, impotence or incontinence Brachytherapy is a new salvage treatment being evaluated in the United States (Phase II study of the Radiation Therapy Oncology Group No. 0526). Several retrospective trials have shown very encouraging results in terms of acute toxicity and biochemical control in the short term. Thus, a team from Mount Sinai in New York recently published for the first time 10 years retrospective results with this approach. In their experience after treatment failures with external beam radiotherapy or brachytherapy, a dose of 122 Gy was delivered over 90% of the prostate gland. Doing this they observed biochemical control rates and survival specific of 54 % and 96 %, respectively at 10 years, with an hormone treatment associated (median 6 months) in 84 % of cases. Four patients had grade 3 toxicity or higher (11%). To reduce the rate of late toxicities the team from the University Of California San Francisco (UCSF), tested focal brachytherapy guided by functional MRI (MRI spectroscopy) to re-treat local recurrence after initial brachytherapy as monotherapy or boost. By delivering 144 Gy on recidivism objectified on MRI, the authors observed that a minimal dose of 37Gy covered 90 % of the prostate gland to treat the risk of microscopic disease. Doing this, the rate of observed toxicities and biochemical control appeared encouraging, with a median follow-up of 2 years, since no grade 3 toxicity was observed and 74% of patients achieved a PSA nadir <0.5 ng / mL without associated hormone. In case of external radiation or brachytherapy, several attempts proposed to associate an injection of hyaluronic acid gel to the prostate - rectum interface to spare healthy tissue irradiated and thus reduce the rate of radiation proctitis. The feasibility of implementing this gel has been demonstrated in patients with non- irradiated tissues. No inherent toxicity of the injection of hyaluronic acid gel has been described after prostate brachytherapy first line. The feasibility of this injection remains unproven to date on patients previously irradiated externally or by brachytherapy. We hypothesize that the risk of radiation proctitis and fistulas front prostate could be reduced using this technique in this indication. We propose to carry out a French prospective multicenter phase II trial combining brachytherapy remedial with an injection of hyaluronic acid after surgery to reduce the risk of radiation proctitis and / or recto -urinary fistula in a patient population hyper- selected with a high probability of isolated local recurrence.
This study was a 2-arm randomized control trial (RCT) designed to test a multi-modal smartphone data collection system that provided mobile monitoring of schizophrenia to detect early signs of relapse. The RCT compared an arm with participants who received treatment as usual with an arm that received the smartphone system for a year.
Within community with high incidence of HCC, stretching the limits could be justified based on tumor characters and its biological behavior
This phase I trial studies the side effects and best dose of inotuzumab ozogamicin when given together with combination chemotherapy in treating patients with relapsed or refractory acute leukemia. Immunotoxins, such as inotuzumab ozogamicin, can find cancer cells that express cluster of differentiation (CD)22 and kill them without harming normal cells. Drugs used in chemotherapy, such as cyclophosphamide, vincristine sulfate, and prednisone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving inotuzumab ozogamicin together with combination chemotherapy may kill more cancer cells.
The purpose of this post market clinical investigation is to complete preliminary evaluation on whether or not concomitant renal denervation with the EnligHTN™ Renal Denervation System and cardiac ablation will result in improved outcomes as compared to ablation alone in patients with uncontrolled hypertension being treated for Atrial Fibrillation
This phase I/II studies the side effects and best dose of natural killer cells before and after donor stem cell transplant and to see how well they work in treating patients with acute myeloid leukemia, myelodysplastic syndrome, or chronic myelogenous leukemia. Giving chemotherapy with or without total body irradiation before a donor peripheral blood stem cell or bone marrow transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells and natural killer cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets.
The primary objective of this study is to evaluate the ability of PET-MRI and to detect a local site recurrence during the first year of follow-up after RFA or MWA of colorectal liver metastases (CRLM) as compared with contrast enhanced (ce) CT and PET-CT. Standard reference will be clear focal uptake in the rim of the lesion on PET-CT, possibly in combination with histology (when available) or clinical follow-up. Secondary outcomes are the inter-observer variability, the ability to diagnose new intrahepatic lesions and in what way PET-MRI is able to influence future treatment compared to PET-CT and ceCT. The patients satisfaction concerning the PET-MRI will be examined with a questionnaire.
Major depressive disorder (MDD) is a common psychiatric condition, mostly treated with antidepressant drugs, which are limited for issues such as refractoriness and adverse effects. In this context, the investigators investigate a non-pharmacological treatment known as transcranial direct current stimulation (tDCS). To prove that tDCS is similarly effective than antidepressants would have a tremendous impact in clinical psychiatry, since tDCS is virtually absent of adverse effects. Its ease of use, portability and low price are also interesting characteristics for using in primary and secondary health care. Thus, our aim is to compare tDCS against a fully dosed, effective antidepressant. The study will be a non-inferiority, randomized, double-blinded, placebo-controlled, three-arm trial comparing active tDCS/placebo pill, sham tDCS/escitalopram 20mg/day and sham tDCS/placebo pill. Our primary aim is to show that tDCS is not inferior to escitalopram 20mg/day with a noninferiority margin of at least 50% of the escitalopram-placebo effect.
This phase I/II trial studies the side effects and best dose of quizartinib when given in combination with azacitidine or cytarabine in treating patients with acute myeloid leukemia or myelodysplastic syndrome that have come back (relapsed) or are not responding to treatment (refractory). Quizartinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as azacitidine and cytarabine work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving quizartinib with azacitidine or cytarabine may work better in patients with acute myeloid leukemia or myelodysplastic syndrome.
