Filter by:Background: Chemoradiation is an important treatment strategy of locally advanced inoperable or unresectable disease. Radiation dose is an independent predictor of a pathological response. In addition, chemotherapy has further impact on the aspect of outcome. Improvements in local treatment delivery are needed to facilitate dose escalation and to minimize toxicity. There have been sequential improvements in tumor localization, radiation planning and delivery over the years. Helical tomotherapy nowadays provides the most precise data on radiotherapy (RT) dose delivered to thoracic malignancies, and allows greater sparing of the heart from doses associated with increased complications. However, heart disease shows a wide spectrum of pathologies, and multiple risk factors related. The damage of the myocytes may lead to not only myocardial perfusion defects, but also in functional deterioration, or even in biomarkers. Since the impact of radiation-induced heart injury in patients with thoracic malignancies (including esophageal cancer, lung cancer, et al) is poorly documented, we try to delineate of RT-related cardiac effects and clinical impacts. Objective: This study aims to investigate the correlation of post-tomotherapy cardiovascular effects with myocardial perfusion and cardiac functional studies. Methods: The study plans to enroll thoracic cancer patients who will undergo local RT after complete staging. Patients will receive global risk scoring assessment (Framingham Risk Score, FRS), blood sampling for basic biochemistry, inflammatory biomarker, and myocardial perfusion image (MPI) at the time points of before and after RT. The results of MPI will be analyzed in qualitative visual interpretation of perfusion patterns, and functional quantitative data for cardiac functional parameters as well. The patients will be regular followed-up in CV OPD, following clinical judgement and guideline. The association between baseline and follow-up MPI, biomarker and clinical presentation will be further investigated. Expected results: We will obtain myocardial perfusion visual qualitative data in patients who received locoregional RT, respectively. These results will help in the understanding of pathophysiology, clinical management and follow-up of suspected RT-related heart disease.
This phase I trial studies the side effects and best dose of bevacizumab and temsirolimus alone or in combination with valproic acid or cetuximab in treating patients with a malignancy that has spread to other places in the body or other disease that is not cancerous. Immunotherapy with bevacizumab and cetuximab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as valproic acid, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether bevacizumab and temsirolimus work better when given alone or with valproic acid or cetuximab in treating patients with a malignancy or other disease that is not cancerous.
The purpose of this study is to evaluate clinical, dosimetrical, functional, biological and genetic factors in predicting chemo-radiotherapy induced lung and esophagus injury.
