Filter by:Aim of the study is to assess efficacy of a short course radiation treatment in patients with complicated bone metastases
Aim of the study is to evaluate achievement of complete pathologic response (pCR) in high-risk rectal cancer treated with neoadjuvant concomitant chemotherapy plus adaptive-intensity modulated imaging-guided radiotherapy
The purpose of this study is to development of more effective treatment tactics of the stereotactic radiotherapy and radiosurgery alone and together with classic radiation therapy in primary inoperabel solid tumors and oligometastastatic cancer.
The investigators aim to investigate the impact of thoracic radiation therapy on diffusion capacity of the lung (primary endpoint: diffusion capacity for nitric oxide, DLNO) and on exhaled nitric oxide.
Objectives: 1. To further validate the predictive efficacy of our established microRNA prediction model of HCC lymph node metastasis. 2. To establish a precise therapeutic mode of prophylactic radiation therapy in high-risk patients with HCC with lymph node metastasis under the guidance of a microRNA prediction model.
Glioblastoma is the most common malignant brain tumor in adults. The primary treatment consists of maximal tumor removal followed by radiotherapy (RT) with concomitant and adjuvant temozolomide. Tumor recurrence after chemoradiotherapy has previously been shown to be predominantly within or at the margin of the irradiated volume, but distant failure are not rare, especially in patients with MGMT methylation.Traditionally, RT has been planned based on on planning CT with co-registered postoperative MRI, with the addition of a clinical target volume margin of 2-3 cm to account for infiltrative odema. To better characterize the disease, more specific physiological and/or metabolical markers of tumor cells, vascularization and hypoxia measured on multiparametric MRI as perfusion, diffusion and spectroscopy alongside with PET tracer like Fluoroéthyl-L-tyrosine ([18F]-FET) are now available and suggest that aggressive areas, like uptake of PET tracer and vascularity are present outside areas of contrast enhancement usually irradiated. These informations could be incorporated to optimize the treatment of radiotherapy.
A propensity- matched study was conducted to investigate the feasibility and safety of adding temozolomide to hypofractionated stereotactic radiotherapy for large brain metastases.
The goal of this trial is to evaluate the effect of the prone crawl treatment position and/or accelerated schedule on acute and late toxicities, as well as quality of life and time management for breast cancer patients receiving whole breast and regional nodal irradiation after breast conserving surgery.
This trial is a multicenter, perspective, non-blinded, randomized controlled phase 3 trial. In order to establish whether the SIB technique can improve the results of twice-daily chemo-RT for patients with LS-SCLC, the investigators will primarily compare survival of patients treated with standard chemotherapy (cisplatin and etoposide) and either SIB twice-daily RT or standard dose twice-daily RT.
The Stupp protocol is the standard treatment of glioblastoma multiform (GBM) which prognosis remains poor. The non-dividing nature of normal brain cells provides an opportunity to enhance the therapeutic ratio by combining radiation with inhibitors of replication-specific DNA repair pathways such poly(ADP-ribose) polymerase (PARP) inhibitors, thus inducing more cytotoxic effects of DNA-damage related to treatment modalities, including alkylating reagents like temozolomide (TMZ). Olaparib, a potent PARP inhibitor, overcomes apoptotic resistance and sensitizes GBM cells for death receptor-mediated apoptosis induced by TRAIL (Tumor necrosis factor-Related Apoptosis Inducing Ligand). Moreover, inhibition of PARP activity increases cellular sensitivity to ionizing radiation: it was even suggested to be more pronounced in tumors than in normal tissue. Lastly, progress in technical imaging and intensity-modulated-radiotherapy (IMRT) techniques provide new possibilities for sparing healthy tissues.
