Active clinical trials for "Recurrence"

This is a multi-center, single arm, open-label, prospective IIS study, which will enroll 40 recurrent MCL patients.The aim is to evaluate the efficacy and safety of bortezomib, fludarabine and cyclophosphamide treatment and also analyze the relationship between NF-kB activity and efficacy of bortezomib treatment and whether NF-kB activity can predict MCL progression.

RATIONALE: Placing a gene that has been created in the laboratory into white blood cells may make the body build an immune response to kill cancer cells. PURPOSE: This clinical trial is studying genetically engineered lymphocyte therapy in treating patients with B-cell leukemia or lymphoma that is resistant or refractory to chemotherapy.

The study will compare the effect of Aspirin versus clopidogrel effect on uterine perfusion in women with unexplained recurrent pregnancy loss with decreased uterine artery pulsatility index. Null hypothesis: Women with recurrent miscarriage have the same blood flow after aspirin or clopidogrel treatment compared to their uterine artery pulsatility index before treatment.

Wright et al (Anticancer Res, 2000) reported the results of a retrospective study on 11 patients with advanced/recurrent endometrial cancers. All patients had multi-site disease and were heavily pretreated with a median of 3 prior chemotherapy regimens. All received bevacizumab combination therapy which was well-tolerated. Two patients had partial responses, 3 had stable disease, while 5 patients progressed. One subject was not assessable for response. The median progression-free interval was 5.4 months for the entire cohort and 8.7 months for those who achieved clinical benefit (PR or SD). The authors concluded that Bevacizumab was well-tolerated and displayed promising anti-neoplastic activity in patients with endometrial cancer.The rationale for combining anti-angiogenic agents, including anti-VEGF antibodies, with cytotoxic chemotherapy stems from a number of preclinical studies showing additive and synergistic anti-tumour activity in a number of solid tumour types. By combining VEGF-targeting agents such as bevacizumab with conventional chemotherapies, it is hoped that these agents will act synergistically, thereby enhancing their anti-tumour efficacy and controlling disease progression. The addition of bevacizumab to chemotherapy has been shown to improve PFS and/or OS in a series of large, randomized Phase III clinical trials in a wide range of tumour types, including mCRC, non-squamous NSCLC, metastatic BC (mBC) and mRCC.

This phase II trial studies how well panitumumab and combination chemotherapy works in treating patients with metastatic colorectal cancer previously treated with combination chemotherapy and bevacizumab. Monoclonal antibodies, such as panitumumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Drugs used in chemotherapy, such as leucovorin calcium, fluorouracil, and irinotecan hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving panitumumab and combination chemotherapy together may kill more tumor cells

To test whether cetuximab improves efficacy/tolerance as compared to methotrexate in first line treatment of unfit patients ³ 70 years old with recurrent and /or metastatic HNSCC. Efficacy assessed by failure free survival

Objective: to evaluate the effectiveness of specialised and sustained intervention with or without parent groups during the initial phase of schizophrenia or related disorders on relapse prevention Methods: A three conditions randomized trial with a duration of five years Participants: 200 consecutively referred patients aged 15-28 years with a first psychotic episode of schizophrenia or related disorder Treatment-conditions: Specialized Treatment of early schizophrenia (ST), ST including Parent groups (ST+P) and Treatment As Usual (TAU). Outcome-measures: cumulative relapse rates and time to first relapse after first remission. Secondary outcome measure: social functioning. Statistical analysis: cumulative relapse rates using life-table methods. The effect of the three interventions on time to first relapse after remission will be compared using Cox regression analysing intention to treat (ITT) grouping.

This is a boron neutron capture therapy (BNCT) combined with image-guided intensity modulation radiotherapy (IG-IMRT) for patients with previously irradiated and locally recurrent head and neck cancer. The primary end points are treatment toxicities and response rate. The secondary endpoints are time to tumor progression, progression-free survival, overall survival and change quality of life. Head and neck(H & N) carcinomas that recur locally after conventional irradiation pose a therapeutic challenge. Boron neutron capture therapy (BNCT) is based on the nuclear capture reaction that occurs when non-radioactive boron is irradiated with neutrons of thermal energy to yield high energy alpha particles and recoiling lithium nuclei. The effect of alpha and 7Li is primarily limited to boron-containing cells. Preferential uptake of boron into cancerous tissue is achieved using boron carriers such as a derivative of phenylalanine, boronophenylalanine (BPA). After administration of BPA by intravenous infusion, the tumor site is irradiated with neutrons, the source of which is currently a nuclear reactor, like the Tsing Hua Open-Pool Reactor (THOR), a 2MW research reactor at National Tsing Hua University (NTHU) in Taiwan. Since it is a target radiotherapy, low complication rate after BNCT can be obtained. However, further local recurrence after BNCT for recurrent H & N cancer was reported in several publications. Image-guided radiation therapy (IGRT) is the process of frequent two and three-dimensional imaging, during a course of radiation treatment, used to direct radiation therapy utilizing the imaging coordinates of the approved radiation treatment plan. IGRT such as Cone-Beam CT (CBCT) using an On-Board Imager (OBI) enhance delivery and further improve outcomes as the treatments create a higher level of precision. By combining BNCT and IG-IMRT, we expect to procure high control rate of recurrent H & N cancer with acceptable toxicity. This study will be the first BNCT plus IG-IMRT trial to treat head and neck cancer in Taiwan.

This study aims to examine the long-term success rate of catheter ablation in non-paroxysmal atrial fibrillation patients using different ablation strategies such as : (i) pulmonary vein antrum isolation (PVAI) + isolation of left atrial posterior wall, (ii) PVAI plus scar homogenization, (iii) PVAI plus isolation of posterior wall plus ablation of non-PV triggers [ PVAI: Pulmonary Vein Antrum Isolation Non-PV triggers: Triggers arising from sites other than pulmonary veins]

This phase I trial studies the side effects of dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) in patients with advanced breast or pancreatic cancer with metastases to the liver or lung. Diagnostic procedures, such as DCE-MRI, may help measure a patient's response to treatment
