Abstract:
Objective To discuss the three-dimensional conformal radiotherapy(3D-CRT) plan for pancreatic tumors.Methods The 3D-CRT plan of 30 cases of primary pancreatic cancer were designed according to the request of the doctors for PTV and the restricted receiving dose of the peripheral normal sensitive organs.The best plan was chosen referring the dose-volume histogram.Results By using ICRU dose reference point(the central point of target)as theunitary dose,95% dose line could be surrounded above 95% of the PTV.Conclusion The focus in different localization can be treated with different design in treating the pancreatic tumors.The reaction to radiotherapy is directly influenced by the volume and dosage of radiation to the normal hepatic tissues.
