Filter by:A multicenter randomized phase II trial of stereotactic body radiotherapy for oligo-progressive metastatic cancers. Eligible patients will be randomized in a 1:2 ratio between receiving their standard of care therapy or stereotactic ablative radiotherapy (SABR) to all sites of oligo-progressive lesions.Radiotherapy will be administered as soon as possible following randomization, and subjects will be followed until next disease progression. The primary outcome is progression-free survival (PFS).
This randomized phase II trial studies how well liver surgery and chemotherapy compared to chemotherapy alone work in treating patients with colorectal cancer that has spread to the liver (liver metastases) that can be removed by surgery and that has spread to the lungs (lung metastases) that cannot be removed by surgery. Liver surgery removes a portion of the liver affected by the tumor. Chemotherapy drugs work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Liver surgery and chemotherapy may work better than chemotherapy alone in treating patients with colorectal cancer which has spread to the liver and lungs.
The investigators proposed this randomized study to determine the feasibility of delivering single-fraction 16-Gy versus 3-fraction 24-Gy toward spine metastatic lesion and to evaluate their toxicity profiles. The investigators' analysis will provide robust data as well as predictive factors regarding the outcome after SSRS.
This is a multicentric randomized parallel group open trial comparing 5-year survival of chemotherapy followed by LT (Group LT+C) versus chemotherapy alone (Group C) in patients with confirmed unresectable liver-only metastases, well controlled by chemotherapy (no progression) and extensively explored by modern imaging techniques. The primary objective of the trial is to validate in a large multicentric cohort of selected patients the possibility to obtain at least 50% 5-years survival with LT combined to chemotherapy compared to around 10% with chemotherapy alone.
Cancer that has spread to the brain, or brain metastasis, is difficult to treat. Meclofenamate is a drug which has been shown to reduce brain metastasis growth in the laboratory. This medicine has been used in the past to treat pain. But, in this study, it will be used to prevent new brain metastasis. This is the first time that meclofenamate will be used in patients with brain metastasis. This is a pilot study which means that the purpose of this study is to determine if a larger clinical trial of meclofenamate is possible in patients with brain metastasis. This study also aims to find out what effects, good and/or bad meclofenamate has on the patient and the cancer that has spread to the brain. The investigators also want to learn more about potential effects that this drug may have in the digestive system.
Brain metastases are the most common brain tumors in adults. It is estimated that around 10-30% of cancer patients would develop brain metastases during the course of their illness. Whole brain radiotherapy (WBRT) is the treatment of choice for the majority of patients with brain metastases. WBRT yields high radiologic response rate (27~56%) and is effective in rapid palliation of neurologic symptoms as well as prolongs time to neurocognitive function decline caused by intracranial lesions. By using conventional fractionation, 33% of patients developed late neurocognitive toxicity while memory impairment was the most common symptom. The incidence is even higher when a formal and sensitive neurocognitive assessment was prospectively evaluated. With more long-term survivors nowadays, it has become increasingly important to minimize neurocognitive function decline and maintain quality of life in patients with brain metastasis. The function of hippocampus is cooperation in learning, consolidation and retrieval of information and essential for formation of new memories. Bilateral and unilateral radiation injury of the hippocampus is known to alter learning and memory formation. Several preclinical studies support the hypothesis of hippocampus-mediated cognitive dysfunction by ionizing radiation. Clinical studies show increase in radiation dose to hippocampus is associated with subsequent neurocognitive function impairment in adult and pediatric patients. Furthermore, the preliminary result of Radiation Therapy Oncology Group (RTOG) 0933 suggested hippocampal avoidance significant reduce the mean relative decline at 4 months from 30% in historical cohort with WBRT to 7% in experimental cohort. Previous studies showed brain structures other than hippocampus are also associated with radiation-induced decline in neurocognitive function. There is presence of placebo effect for interventions seeking improvement in neurocognitive function. In present study, a single blind randomized phase II trial is designed to investigate the effectiveness of neurocognitive function preservation using conformal WBRT with or without hippocampal avoidance.
This randomized phase II/III trial studies how well standard of care therapy with stereotactic radiosurgery and/or surgery works and compares it to standard of care therapy alone in treating patients with breast cancer that has spread to one or two locations in the body (limited metastatic) that are previously untreated. Standard of care therapy comprising chemotherapy, hormonal therapy, biological therapy, and others may help stop the spread of tumor cells. Radiation therapy and/or surgery is usually only given with standard of care therapy to relieve pain; however, in patients with limited metastatic breast cancer, stereotactic radiosurgery, also known as stereotactic body radiation therapy, may be able to send x-rays directly to the tumor and cause less damage to normal tissue and surgery may be able to effectively remove the metastatic tumor cells. It is not yet known whether standard of care therapy is more effective with stereotactic radiosurgery and/or surgery in treating limited metastatic breast cancer.
This study is a phase II, prospective, open-label, single arm, single center study of the efficacy and safety of concurrent conventional transarterial chemoembolization (TACE) and sorafenib in patients with hepatocellular carcinoma and extrahepatic metastasis. All of the 55 patients with hepatocellular carcinoma and newly diagnosed extrahepatic (lung, bone, lymph node, adrenal gland) metastasis will be included. On demand conventional TACE will be performed in all the patients after enrollment and can be continued until intrahepatic CR, TACE failure or consent withdrawal. Sorafenib will be started 3-7 days after the first and each subsequent TACE and stopped one day before next TACE and will be continued until sorafenib failure, consent withdrawal or condition worsening by clinical decision. Repeated on-demand TACE and sorafenib should continue until the criteria for treatment discontinuation are met. After initiation of sorafenib combination treatment, patients will be seen and will perform routine examination at week 4 and, after then routine examination will be followed every 6 ± 2 weeks.
This randomized phase III trial studies how well combination chemotherapy with or without ganitumab works in treating patients with newly diagnosed Ewing sarcoma that has spread to other parts of the body. Treatment with drugs that block the IGF-1R pathway, such as ganitumab, may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as vincristine, doxorubicin, cyclophosphamide, ifosfamide, and etoposide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether adding ganitumab to combination chemotherapy is more effective in treating patients with newly diagnosed metastatic Ewing sarcoma.
