Pancreatic Cancer
Conditions
Brief summary
The only curative option for pancreatic cancer patients is surgery, but the patients within 20% of them are possible for a radical surgery. Accordingly, concurrent chemo-radiation therapy is generally used for palliation of unresectable pancreatic cancer patients. So far, the use of 5-fluorouracil (5-FU) was the traditional method of chemotherapy. However, these days, oral anti-cancer medicine, capecitabine(Xeloda®), was developed and considered as an alternative medicine of 5-fluorouracil (5-FU). Furthermore, according to the recent results of clinical trials, the clinical use of capecitabine(Xeloda®) with radiation therapy was proved to be very effective and safe. The purpose of this trial is to improve the therapeutic effects by using proton therapy and chemotherapy concurrently.
Interventions
Capecitabine is administered orally at a dose of 800 mg/m2 twice daily (total daily dose 1600mg/ m2) continuous regimen regimen during RT (5 days of treatment followed by a 2 day rest: Saturday and Sunday). Capecitabine is given approximately 12 hours apart and taken orally with water within 30 minutes after ingestion of food (breakfast or dinner).
RADIATIONLocalization, simulation and immobilization
Radiation dose and planning 1. Total dose 55.8Gy, 28 fractions, 6-7 weeks (1.8 Gy/day). A cone down after 45 Gy will be performed to emcompass GTV with a margin of 1-1.5cm. 2. Dose prescription : 90% isodose volume of prescribed dose encompassed PTV 3. The dose-volume histogram (DVH) of targets, such as GTV, CTV, and PTV, and the normal tissues, such as the liver, duodenum, stomach, the kidneys, spinal cord, etc., was calculated.
