Abstract:
We report 2 cases of gastric cancer treated with palliative radiotherapy. Case 1: A 74-year-old man presented with gastric cancer. He had severe anemia caused by tumor bleeding and needed frequent blood transfusions. Radiotherapy of 38.25 Gy in 15 fractions was administered to controlbl eeding. We confirmed hemostasis. Case 2: An 81-year-old man presented with peritonealrecurrence 41 months after operation for remnant gastric cancer. Systemic chemotherapy(S-1)was started, but gastrointestinalobstruction worsened. Radiotherapy of 44 Gy in 22 fractions was performed to improve obstruction. Conclusion: Palliative radiotherapy is minimally invasive and is therefore a treatment option for gastric cancer with bleeding and obstruction.

Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
