[Progression of Anti-oxygen Therapy in Radiation-Induced Lung Injury]

Radiation induced lung injury (RILI) is a serious complication in patients received thoracic radiotherapy. The main clinical symptom of RILI includes short of breath, low fever and cough, seriously affect the survival of patients. How to better prevent and treat RILI is an urgent problem. Target theory, cytokine theory, free radical theory, and vascular endothelial cell damage theory are the main mechanisms of RILI. Among them, reactive oxygen species (ROS) produced during radiotherapy can induce tissue damage throughout the course of RILI, and have a direct effect on both radiation pneumonitis and radiation-induced lung fibrosis. Anti-oxygen therapy including thiol compounds, antioxidant enzymes, and plant antioxidants have been applied in the prevention and treatment of RILI. This article reviews the research and application of antioxidant therapy in RILI.

Clinical presentation, diagnosis, classification and management of peritoneal mesothelioma: a review

Peritoneal mesothelioma (PM) is an uncommon but a serious, and often, fatal primary peritoneal tumour, with increasing incidence worldwide. Conventional systemic chemotherapy, generally based on experience with pleural mesothelioma, usually has disappointing results considering PM as a terminal condition. Patients usually present with non-specific symptoms of abdominal distension and pain making the diagnosis challenging. As PM is confined to the abdomen for all, or much, of its clinical course, a multimodality treatment combining cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) has emerged as a new standard of care, and has been reported to achieve promising survival outcomes and local disease control in selected patients with PM. This review updates the presentation, diagnosis, classification and treatment strategies for PM.
