Radiation-induced hemorrhagic gastritis is an intractable and dangerous condition. We describe a 59-year-old female patient with radiation-induced hemorrhagic gastritis. The patient underwent postoperative radiation therapy with a dose of 54 Gy in 30 fractions after a radical operation for a Klatskin tumor. Radiation volume included the gastric antrum. Approximately three months after radiation therapy, she was admitted for melena and anemia. Esophagogastroduodenoscopy showed an area of bleeding in the gastric antrum that was so diffuse that effective laser coagulation was not feasible. After failure of various treatments and transfusion of 7,040 mL of packed red blood cells, we successfully stopped the hemorrhage using oral prednisolone treatment. Based on this case, we think that oral prednisolone treatment can be tried as a first treatment for potentially life-threatening radiation-induced hemorrhagic gastritis.
Many Korean cancer patients misunderstand the aims of treatment and half of participants do not want further information. Physicians should address whether specific interventions can solve these barriers so that Korean cancer patients can make truly autonomous treatment decisions.
In recent years, the verification of the three-dimensional (3-D) distribution of the absorbed dose in the tumor volume has been significantly considered in a radiation-therapy treatment plan. This study produced a polymer gel under a normoxic condition by using antioxidants, instead of using a polymer gel dosimeter, that can only be applied under a hypoxic condition using nitrogen gas. Also, this study investigated the characteristics of normoxic polymer gel for various compositions of the gel compound samples to produce practical polymer gels and composite polymer gels with five different compositions. Magnetic resonance images, R2 mapping images, dose-R2 response curves were analyzed for various composition ratios, and dose distributions. This study prepared polymer gels (Tetrakis hydroxymethyl phosphonium chloride-normoxic methacrylic acid-gelatin, TENOMAG) under a normoxic condition by using antioxidants and obtained a composition ratio that could be applied practically in clinics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
