To explore the efficacy of radiotherapy plus toripalimab Versus standard treatment of sorafenib in advanced hepatocellular carcinoma with Portal Vein/Hepatic vein Tumor Thrombosis.
Stereotactic radiation therapy is an important and common method of treating brain metastases in patients with malignant disease. Today, however, there are no methods available to determine the metastasis' radiation sensitivity in advance and treatment responses can only be seen by changing of the size of the metastasis on conventional X-ray examinations, computed tomography (CT) and magnetic resonance imaging (MRI). Changes in the size of the metastases is something that is often seen weeks / months after treatment is completed. At Lund University Hospital, a new imaging technique, diffusional variance decomposition (DIVIDE), has now been developed. With this technique, the scatter in isotropic and anisotropic diffusion can be measured for each measuring point, which provides significantly more information about the properties of the tissue compared to current methods.
The role of radiotherapy is well established in the management of early stage lung cancer or as part of a multidisciplinary approach of locally advanced lung cancer (1). Recent advances in Cyberknife© technology, which is a robotic system of stereotactic irradiation including localisation and real time lesion-tracking, has led to an increase in accuracy and potentially in efficiency of the irradiation of tumor field (2)(3). According to several studies, promising results in local control and survival rates have been achieved in patients suffering from primary lung cancer or peripheral lung metastasis treated with Cyberknife© (4)(5)(6)(7)(8). Fiducial markers are implanted in or near a tumor in a configuration defining a COM (center of mass) guiding the Cyberknife for tumor localization. Tumor movement is then synchronized to respiratory cycle motion during treatment which reduces toxicity of non target lung tissue irradiation. Change in marker positioning leads to COM alterations, thus limiting detection by the tracking system. Percutaneous (9)(10)(11) (12), endovascular (12)(13) fiducial implantation or by means of bronchoscopic devices (14)(15)(16)(17)(18) are three techniques that have been validated in previous studies as feasible and safe procedures, providing accurate tracking. Few studies are currently available in the litterature comparing these modalities (19)(20). The percutaneous implantation technique will not be considered for this study because this technique is associated with a high risk of pneumothorax (9). Both the endobronchial and endovascular technique have been described in the literature with equivalent success rate (87-90%) in intention to treat (21)(22). One of the endpoints of this study is to verify that these results are reproducible in our institution where both techniques are currently available and to investigate other secondary endpoints such as fiducial marker migration after placement, complications rates and procedure time.
Patients with recurrent or metastatic uterine cervical squamous carcinoma have very poor prognosis. For eligible patients, radiotherapy remains the choice, which has the most effective impact on the survival periods. On the hand, anti-angiogenic therapy has been proved to be promising treatment for recurrent or advanced cervical carcinomas. This study aims to discover the objective response of combination therapy with nimotuzumab (an anti-epidermal growth factor receptor [EGFR] IgG1 humanized monoclonal antibody) and radiotherapy in recurrent or metastatic uterine cervical squamous carcinoma in a single-arm, open, phase 2 clinical trial. The primary endpoint is the objective response rate evaluated by imaging methods. The second endpoints are the progression-free survival and overall survival. The treatment toxicity is regarded as one the second endpoint.
This prospective, single-arm study is conducted to investigate the safety and efficacy of Sintilimab combined with hypofractionated radiotherapy in patients with microsatellite instability-high (MSI-H)/ DNA mismatch repair-deficient (dMMR) non-metastatic rectal cancer.
The purpose of this study is to determine whether any eventual skin damage caused by radiation therapy can be detected and monitored at a subclinical level via optical coherence tomography (OCT). Another key question is whether subclinical OCT detected skin damage correlates with acute and late clinical toxicity.
The hypothesis for this study is that addition of a moderate dose of radiotherapy to the primary tumor and mediastinal nodes after three months of medical treatment could reduce the tumor burden, partly as an abscopal effect, and thereby improving quality of life and possible also prolonging survival for stage IV NSCLC.
The main purpose of our study is to investigate the effects of exercise therapy on upper extremity functions in patients receiving radiotherapy to the axillary region after breast cancer surgery.
aim of this cross-over study is to compare sedation with insufflated sevoflurane and intravenous sedation for pediatric radiotherapy patients
