Filter by:This study evaluates the feasibility and preliminary efficacy of a brief cognitive-behavioural program designed to improve cognitive functioning in people with brain metastases.
The purpose of the study is to compare the outcome of patients who receive standard treatment versus those who receive preventative radiation and then standard treatment.
The purpose of this study is to find the safest and most effective dose for delivering proton beam to the space containing CSF, brain, and spinal cord, in treating leptomeningeal metastases. The researchers think that using proton beam radiation to treat the space containing CSF, brain, and spinal cord, instead of treating only the areas where the metastasized tumor cells are causing symptoms, would improve the treatment of this disease.
A single institution study to evaluate the safety and tolerability of the combination treatment of nivolumab, ipilimumab, CMP-001 and radiosurgery in patients with metastatic colorectal cancer with liver metastases.
Intrathecal chemotherapy is one of the most important treatment modalities for leptomeningeal metastasis of solid tumors. In the previous retrospective study, it has been proved that concurrent radiotherapy and intrathecal methotrexate for leptomeningeal metastasis from solid tumors with adverse prognostic factors showed great effectiveness and safety. The preliminary results of investigators' current prospective clinical study (Involved-field Radiotherapy Combined With Concurrent Intrathecal-methotrexate Versus Intrathecal-Ara-C for Leptomeningeal Metastases From Solid Tumor: A Randomized Phase II Clinical Trial. ClinicalTrials.gov identification number: NCT03082144) also showed that the regimen of concurrent intrathecal chemotherapy and radiotherapy may serve as an optimal therapeutic option for treatment of leptomeningeal metastases from solid tumors. Pemetrexed is a newer multitargeted antifolate which has shown activity in various tumors. In investigators' current study (Intrathecal Pemetrexed for Recurrent Leptomeningeal Metastasis From Non-small Cell Lung Cancer: A Prospective Pilot Clinical Trial. ClinicalTrials.gov identification number: NCT03101579), the regimen of intrathecal pemetrexed with folic acid and vitamin B12 supplementation may provide higher effectiveness and safety for recurrent leptomeningeal metastasis from non-small cell lung cancer. Therefore, the purpose of the study is to evaluate the tolerability, safety and effectiveness of intrathecal pemetrexed combined with involved-field radiotherapy as the first line treatment in patients with leptomeningeal metastases from malignant solid tumors.
The aim of the trial is to optimize response rates and rates of secondary resections of metastases in patients with initially non-resectable metastatic colorectal cancer Liver Metastasis. The patients will be treated with systemic chemotherapy With irinotecan plus hepatic arterial infusion With floxuridine and oxaliplatin
Stereotactic ablative body radiotherapy (SABR) can be considered for patients with so-called "oligometastatic" disease. However, since this is a relatively new technique, information on the optimal scheduling is lacking. Even prospective randomized trials on SABR for oligometastases typically allow different fractionation schedules to be used. This is especially true for non-spine bone and lymph node metastases, where the literature is scarce to non-existent. There is also emerging evidence that SABR can stimulate the immune response, by a variety of mechanisms such as increasing TLR4 expression on dendritic cells, increasing priming of T cells in draining lymph nodes, and increasing tumor cell antigen presentation by dendritic cells. Again, it is not clear which fractionation schedule elicits the most robust immune response. Therefore, it is opportune to compare the most commonly used stereotactic regimens regarding toxicity, efficacy, and immune priming. This trial is a non-randomized prospective phase I trial determining a regimen of choice for patients with non-spine bone and lymph node oligometastases (≤ 3 lesions). The metastatic lesion(s) must be visible on CT and < 5 cm in largest diameter. A total of ninety patients will be consecutively included in three different fractionation regimens. They will be offered stereotactic ablative radiotherapy to all metastatic lesions in 5, 3 or 1 fractions. Dose-limiting toxicity (DLT), defined as any acute grade 3 or 4 toxicity, will be recorded as the primary endpoint. Overall acute and late toxicity, quality of life, local control, and progression-free survival are secondary endpoints. Liquid biopsies will be collected throughout the course of this trial, i.e. at simulation, after each fraction and at 6 months after the end of the radiotherapy. Translational research will focus on assessment of circulating cytokines and flow cytometry analysis of immune cells.
The aim of this clinical trial is to investigate whether the therapeutic response of chemotherapy can be improved by focused ultrasound and microbubbles. Patients with liver metastases from breast cancer and colorectal cancer will be included. Computer Tomography (CT) will be performed as a baseline scan before treatment start. Two metastases in each patients liver will be preselected and randomized to either "target lesion" to be treated or "control lesion" to serve as internal control. The patients will receive conventional treatment with chemotherapy according to national guidelines. After intravenous chemotherapy infusion the patients will receive the experimental treatment. The target lesion will get focused ultrasound (FUS). Simultaneously repeated bolus-doses of microbubbles will be administered intravenously. The investigators will measure the difference in response between FUS- treated and -untreated lesions on the post-treatment CT scan.
Almost 50 % of papillary thyroid cancer (PTC) patients have central lymph node metastases (CLNM), which are associated with a high risk of persistent or recurrent disease. However, the practice of performing a prophylactic central lymph node dissection (PCLND) routinely remains controversial. The proponents argue that without a PCLND, PTC patients with positive lymph nodes have an increased risk of local recurrence, and postponed node dissection leads to with 5-6 fold higher risk of morbidity. If performed, PCLND in clinical node negative patients increases staging to pN1 in more than 50% of the cases without increasing survival. The complication rate in PCLND is lower when compared to a technically challenging re-exploration in recurrent disease, with reported incidences of 0.6% and 7.3-20%, respectively. Opponents of routine PCLND point out the lack of randomized clinical trials and object to treatment-induced hypo-parathyroidism and recurrent nerve damage for the N0 patients. Currently, no diagnostic tool is available which reliably identifies these patient categories. Therefore, there is a clear need for novel diagnostic imaging modalities that overcome this issue. Molecular Fluorescence Guided Surgery (MFGS) is potentially such a diagnostic tool. The administration of NIR fluorescent tracers can increase detection accuracy of cancer and nodal metastatic tissue using macroscopic MFGS. Therefore, we aimed to identify a GMP-produced near infrared (NIR) tracer that potentially has a high target-to-background ratio in PTC compared to normal thyroid tissue. Tyrosine-protein kinase Met (c-Met) is significantly upregulated at the protein level in PTC compared to normal thyroid tissue. The investigators therefore hypothesize that the GMP-produced NIR-fluorescent tracer EMI-137 (targeting c-Met, peak emission at 675 nm range) might be useful for intraoperative imaging of PTC and nodal metastases. The investigators' aim is to investigate if the administration of EMI-137 is a feasible approach to detect PTC nodal metastases. Ultimately, this method might be useful to improve patient selection for CLND. Eventually, we might also be able to visualize multifocality, more selective lateral neck dissections and asses residual tissue after thyroidectomy. Ultimately, all of these strategies may reduce overtreatment, morbidity, and costs while maintaining the same or better effectiveness with a lower recurrence rate and improved quality of life.
Rectal cancer is a common diagnosis. The prognosis after treatment has improved over the last decades, partly due to neoadjuvant radio(chemo)therapy, but also due to improved surgical technique (TME) and, in certain cases, due to adjuvant therapy after surgery. For some 15-20 years, treatment of metastasis has changed; liver- and lung metastasis in certain situations are surgically removed, or in the liver, treated with ablation (radio-frequency). During the same period the possibilities for chemotherapy of metastatic disease have improved, with new drugs and more drug regimens. These changes in treatment pathways have required changes in how patients with newly diagnosed rectal cancer are "worked up" pre-treatment. Starting in the early 2000s magnetic resonance imaging of the pelvic area has developed and is today mandatory to be able to adequately stage the tumour and plan for the multi-modal treatment before and after surgery. In many hospitals the set-up is a combination of computed tomography of the abdomen and chest and to this a MRI of the pelvic organs is added, whereas others have adopted MRI also for the abdominal part, thus having an MRI of the liver for the diagnosis of liver metastasis initially, before surgery. For the chest organs, CT is still normative. MRI has a higher sensitivity and specificity to detect liver metastasis, compared with CT. In order to plan the liver surgery/ablations, most liver surgeons rely on MRI for detailed information about the position of the metastasis and the relation to large vessels. The aim of this study is to examine the possible differences in percentage of patients requiring further radiology examinations after basic set-up comparing the routine of initial MRI of abdomen (and pelvic organs) with the routine of initial CT of the abdomen (and MRI of the pelvic organs). Further included is an analysis of the rate of liver metastasis using the two different routines, and finally outcome over 12 months in terms of liver treatment for metastasis.
