Filter by:Hypo-fractured radiotherapy in stereotactic conditions (RSHF) of bone metastases allows high doses to be delivered to the affected bone segment while sparing adjacent healthy tissues as well as possible. In addition, it not only reduces pain and prevents spinal cord compression, but also improves long-term control of metastatic disease. Zoledronic acid reduces bone complications. The economic literature shows that stereotactic radiotherapy, like zoledronic acid, are cost-effective strategies in these indications. The objective of this research project is to evaluate the efficiency of adding zoledronic acid to stereotactic radiotherapy in the treatment of vertebral metastases.
Following treatment for a primary extremity sarcoma, patients remain at risk for the development of local and systemic disease recurrence. Metastasis (distant recurrence) to the lung is the most frequent single location of disease recurrence in sarcoma patients, occurring in almost half of all patients. Therefore, careful post-operative surveillance is an integral element of patient care. However, the detection of metastases does not necessarily affect long-term survival and may negatively impact quality of life. Surveillance strategies have not been well researched and have been identified as the top research priority in the extremity sarcoma field. Using a 2X2 factorial design to maximize efficiency and reduce overall trial costs, the SAFETY trial will randomize 830 extremity soft-tissue sarcoma (STS) patients to determine the effect of surveillance strategy on overall patient survival after surgery for a STS of the extremity by comparing the effectiveness of both surveillance frequency (every 3 vs. every 6 months) and imaging modality (CT scans vs. chest radiographs).
Breast cancer is the second leading cause of death for women around the world. Notably, most breast cancer patients die from tumor metastases in the liver, lungs, bones, or brain, not the primary tumor itself. Currently, clinicians are generally successful in treating primary tumors using standard protocols that are based on tumor sub-type and staging, as well as by the presence or absence of prognostic biomarkers. However, it remains difficult to assess in advance the likelihood of metastasis or relapse in any given patient.Physicians can only rely on regular post-treatment screening to monitor any secondary onset. By the time metastasis is detected, the golden window for treatment adjustment has often already passed. This project proposes to develop an analytical tool for predicting the likelihood of metastasis in breast cancer patients post-treatment using imaging and genomic data. We will evaluate our prediction model using prospectively-collected patient data. This new prognostic tool will enable physicians to adjust and tailor therapeutic strategies to each patient in a timely manner. Overall, the tool will personalize patient care, and improve their survival chances and quality of life.
In this study the characteristics and alterations of the gut microbiome during chemotherapy for metastasized or irresectable CRC are studied, as well as the relation between the gut microbiome and the effects of chemotherapy.
Pyrotinib is an oral tyrosine kinase inhibitor targeting both HER1, HER2 and HER4 receptors. This study is a single-arm, prospective, open label clinical study of pyrotinib plus vinorelbine as the therapy of brain metastases from HER2-positive metastatic breast cancer.
The presence of lymph node metastasis is an important factor in determining the appropriate treatment plan in patients with OSCC. However, detection of lymph node metastases by means of current imaging modalities is limited. 20-30% of patients with a clinically negative neck (cN0) harbour lymph node metastasis that were not detected during clinical diagnostic workup, which are referred to as occult lymph node metastasis. Therefore, patients with a risk of lymph node metastasis higher than 20% undergo a sentinel node procedure (SNP) or elective neck dissection (END), which means that a substantial part of patients is overtreated. There is need for an additional non-invasive diagnostic tool that can identify lymph node metastasis and thereby support the decision making for treatment of the neck. The main objective of this study is to evaluate if EGFR-positive cervical lymph node metastasis can be detected non-invasively with multispectral optoacoustic imaging using cetuximab-800CW as contrast agent in patients with oral squamous cell carcinoma.
It was difficult to obtain clinical benefits through traditional chemotherapy and radiotherapy for the patients who have recurrence or metastasis tumor even though they have received first-line chemotherapy or combined radiotherapy before, but failed.The aim of this study was to evaluate the safety and efficacy of apatinib, an anti-angiogenesis drug, in the treatment of patients with advanced esophageal squamous cell carcinoma who had recurrence or metastasis after radical resection
To examine survival of patients who underwent minimally invasive versus open liver resection for colorectal cancer with liver metastases.
The incidence of node metastases in papillary thyroid carcinoma (PTC) is high, ranging from 20% to 90%. Prophylactic central lymph node compartment dissection (CLND), suggested from the latest guidelines for high-risk tumors, meets resistance due to the high incidence of postoperative complications. Recently, new molecular biologic techniques, such as One Step Nucleic Acid Amplification (OSNA), have spread widely, allowing to quickly isolate, amplify and quantify mRNA encoding for proteins selectively present in neoplastic cells, as Cytokeratine-19. The aim of this study is to evaluate the application of OSNA to intraoperative diagnosis of node metastases of PTC.
The goal of this study is to understand the immunologic effects radioembolization has on the immune system. This will be done by evaluating the changes on biopsy, peripheral blood monocytes, and cytokines.
