Brain Metastases Clinical Trials

This study will apply novel MRI approaches with established sensitivity to tissue oxygen consumption and perfusion to predict hypoxia-associated radiation resistance, manifested as tumor recurrence and progression post-treatment. Read Less

Brain metastases are a source of much morbidity and mortality in adults with primary solid malignant tumors. With improvements in systemic therapy that prolong survival but have limited central nervous system penetration, patients with brain metastases are at increasing risk of developing and experiencing long-term side effects from treatment of brain metastases. The overarching goal of this study is to better understand the determinants of RT-associated changes in white and gray matter function and associated neurocognitive decline. Read Less

The primary objective of this study is to evaluate the diagnostic performance of the CONVIVO confocal endomicroscope in discriminating between normal and abnormal tissue in vivo during brain tumor surgery. The interpretation of intraoperative images obtained in situ will be tested against conventional histologic evaluation of targeted biopsies from imaged tissue. The study team hypothesize that there will be a high degree of correlation between images obtained with the CONVIVO system and conventional histologic interpretation. Read Less

Esophagectomy is the cornerstone of the curative treatment of esophageal carcinoma. Despite this treatment, patients can suffer from locoregional or distant metastatic disease and only a very selected group of patients can be cured: mostly those with recurrence in one single organ. Brain metastases are rare after esophagectomy for cancer, but they have a serious impact on survival. Agressive treatment is often moren difficult for brain metastases compared to other metastases and some risk factors have been identified earlier. There is an impression that the incidence of brain metastases in esophageal cancer patients has increased since the introduction of neoadjuvant treatment schemes. However, this is not clear yet. A potential explanation could be that chemotherapy disturbs the blood-brain-barrier, hereby facilitating the migration of tumor cells to the brain. The purpose of this study is to retrospectively analyze the incidence and potential risk factors of brain metastases in patients who underwent esophagectomy for esophageal cancer. Patients treated between 2000 and 2019 will be included and outcome parameters are Odds Ratio for brain metastases (comparison between primary surgery and neoadjuvant treatment followed by surgery), time to recurrence and risk factors, number and characteristics of the brain metastases.
