Active clinical trials for "Recurrence"

The giant cell tumor (GTC) is an aggressive benign bone tumor, growing at the metaphyseal-epiphyseal regions of long bones, especially around the knee and the distal radius.It is responsible for bony destruction in para-articular zone fracture and leading to the breakdown and destruction of the underlying joint. Histologically, the tumor cell contains a contingent of monocytic cells round, a contingent of giant type cell of type osteoclastic responsible for bone resorption that accompanies these tumors and a contingent of lengthened cells fibroblast-like considered to be contingent tumor. The treatment is exclusively surgical; or by resection of the lesion which takes away tumour and its environment, solution which, if it prevents local recurrence, imposes an important bony and articular reconstruction, always limited and deteriorating rapidly over time in these young patients; or by curettage of lesion, by "hollowing-out" of the bone, creating a hole which it will be necessary to fill up by a bony grafting or a substitute of the bone (cement). This last solution, if it preserves a better function, exposes at risk of local recurrence,putting into play the prognosis of articulation near, most often the knee.Despite different local adjuvants treatments used during surgical operation, after having curetted the cavity and before filling it up, the recidivism rates vary from 12 % to 41 % (average 25 %) in literature. The beneficial effect of the adjuvants therapeutics suggests the concept broadly accepted by a tumoral microscopic residual at the origin of the local recidivism .Biphosphonates (BP) is molecules which settle in vivo on the hydroxyapatite of the bone; they inhibit the recruitment of the osteoclast forerunners and the activity of mature osteoclast. Besides, biphosphonates containing some nitrogen (N-BP), leads to the apoptose of mature osteoclast. These molecules also have a direct effect on tumor cells , causing apoptosis of neoplastic cells of myeloma, of breast cancer. Clinical controlled studies confirm the experimental data of N-BP. Two work also showed their effect on osteoclasts and stroma cells of tumours with giant cells but no clinical study assessed potential on the prevention of the local recurrence. The investigators offer a study phase 2 of the effectiveness of N-BP (acid zoledronique) on the prevention of the local recurrence of tumours with primary huge cells after surgical treatment by curettage - filing by a surgeon referent in oncologic orthopedic surgery. Number of patients: 24

Orthotopic liver transplantation (OLT) is the treatment of choice for patients with Hepatitis C Virus (HCV) infection and end-stage liver disease or hepatocellular carcinoma; infection of the graft and hepatitis C recurrence is universal after OLT and recurrent HCV hepatitis often follows an accelerated course after OLT, with rapid histological recurrence and cirrhosis. These very poor outcome significantly affect graft and patient survival and reduces the benefit of transplantation for this indication. Therapeutic strategies are not available; high viral load, high prevalence of genotype 1b and need of dose reduction of interferon and ribavirin because of the side effects or intolerance, together with the interference of immunosuppressive drugs, resulted in the vast majority of the patients in failure in obtaining viral eradication. Recently, Silibinin, has been studied and reported to be capable to act as potent antiviral agent in patients with HCV; it has been used successfully in a protocol of a 14 day intravenous infusion in previous non-responders to peginterferon/ribavirin therapy. In view of his postulated profile of safety, it seems an ideal drug to be used in the setting of HCV recurrent patients after liver transplant. Aim of this prospective, randomized, double-blind, placebo-controlled, parallel group study is to determine the therapeutic effect of Legalon SIL in the prevention of HCV reinfection in chronically infected hepatitis C patients after OLT. Awaiting orthotopic liver transplantation patients affected by HCV will be randomised 3:1 to receive, in addition to their current therapy, silibinin 20mg/kg/day (Legalon SIL) or placebo infused over 2 hours from 14 to 21 consecutive days; in addition, patients will receive treatment with silibinin 20mg/kg/day (Legalon SIL), infused over 2 hours, for 7 days after transplant. The Primary Efficacy endpoint is to achieve sustained virological response (SVR) while Secondary Efficacy endpoints are to evaluate the virologic response, the percentage of patients who has a decreased of at least 2 log10 the levels of HCV-RNA and the safety of Legalon SIL in this population.

Panobinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as fluorouracil and leucovorin calcium, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving panobinostat together with fluorouracil and leucovorin calcium may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and the best dose of giving panobinostat, fluorouracil, and leucovorin calcium together in treating patients with stage IV colorectal cancer who did not respond to previous fluorouracil-based chemotherapy.

This study is being done to determine if an investigational cancer treatment called vorinostat combined with fractionated stereotactic radiation therapy (FSRT) is effective in treating recurrent high grade gliomas. The main goal of this research study is to determine the highest dose of vorinostat that can be given to patients with recurrent tumors. The study will also determine the potential side effects and safety of these treatment combinations. Vorinostat is a small molecule inhibitor of histone deacetylase (HDAC). HDAC inhibitors help unravel the deoxyribonucleic acid (DNA) of the cancer cells and make them more susceptible to the treatment with radiation.

The purpose of this study is to test the efficacy of a single injection of Canakinumab on AF recurrences within 6 months after electrical cardioversion in patients with persistent AF.

This phase II trial studies how well alisertib with and without rituximab works in treating patients with relapsed or refractory B-cell non-Hodgkin lymphoma. Alisertib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving alisertib with and without rituximab may be an effective treatment for B-cell non-Hodgkin lymphoma

This pilot phase I/II trial studies the side effects and best of dose ipilimumab when given together with local radiation therapy and to see how well it works in treating patients with recurrent melanoma, non-Hodgkin lymphoma, colon, or rectal cancer. Monoclonal antibodies, such as ipilimumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Radiation therapy uses high energy x rays to kill cancer cells. Giving monoclonal antibody therapy together with radiation therapy may be an effective treatment for melanoma, non-Hodgkin lymphoma, colon, or rectal cancer

This phase I trial studies the side effects and the safety of injecting HSV1716 (a new experimental therapy) into or near the tumor resection cavity. The injection will be done at the time of surgery. HSV1716 is a virus that has a gene which has been changed or removed (mutated) in such a way that lets the virus multiply in dividing cells of the tumor and kills the tumor cells.

This phase II trial studies how well lenalidomide and obinutuzumab work in treating patients with chronic lymphocytic leukemia or small lymphocytic lymphoma that has come back (recurrent) or does not respond to treatment (refractory). Drugs used in chemotherapy, such as lenalidomide, 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. Monoclonal antibodies, such as obinutuzumab, may interfere with the ability of cancer cells to grow and spread. Giving lenalidomide and obinutuzumab may work better in treating patients with chronic lymphocytic leukemia or small lymphocytic lymphoma.

Background: The frequency of recurrent aphthous stomatitis (RAS), the most common oral mucosa lesions seen in primary care, is up to 25% in the general population. Sublingual vitamin B12 treatment, 1000 mcg per day for 6 months was found to be effective for patients suffering from RAS, regardless of the serum vitamin B12 level. However, the optimal therapeutic dose of vitamin B12 treatment remains unclear. Working hypothesis and aims: Aim-To assesses the influence of different vitamin B12 treatment doses on the frequency and severity of RAS episodes. Working hypothesis- The group receiving the higher dose of vitamin B12 treatment will have the lower frequency and severity of RAS episodes; the reaction will be faster. Methods: randomized, double blind, intervention study. Study population: 75 patients in three groups (total of 225 patients): Group I- will receive sublingual vitamin B12 treatment, 1000 mcg per day for 6 months Group II- will receive sublingual vitamin B12 treatment, 100 mcg per day for 6 months Group I- will receive sublingual vitamin B12 treatment, 2000 mcg per day for 6 months Study design: Study participates will be followed through three study periods: The first period- three months prior to receiving active treatment, the second period- six month of active treatment (with randomization to study groups), and the third period- three month after finishing active treatment. Frequency and severity of RAS episodes will be recorded by the patient with "aphthous diary" that will be filled daily during all study period (12 months). Expected results: This study will allow us to identify optimal dose of vitamin B12 treatment that will achieve faster and longer remission of RAS episodes. Importance: This is a very common problem in the population. Study results will help to identify optimal doses of vitamin B12 needed to treat RAS. Probable implications to Medicine: study results are supposed to give faster and better treatment for RAS episodes
