Abstract
Objective To explore the advantages and disadvantages of three differert treatment plans (three-field, four-field, three-field crossing) in three-dimensional conformal radiotherapy for pancreatic cancers. Methods For 10 patients with pancreatic cancer and received radiation therapy, three-field, four-field, three-field crossing treatment plans were designed with a total dose of 60Gy in the same treatment planning system. PTV and the tolerated dose of normal tissues were analyzed based on the DVH dose volume histogram, by which the three treatment plans were compared. Results The difference of conformity in target and tolerated dose of the three treatment plans were not clear. The three-field crossing was better than the other two plans in protecting spinal marrow, but there was almost no difference in protecting liver and spleen. It was worse than the other two plans in prolecting kidneys. Conclusion According to the target volume and the location of the tumor, different treatment plans should be applied. For the tumors in the head of the pancreas which near to the intestine and liver, four-field or three-field crossing are usually applied; while for the tumors in the end of the pancreas which near to the stomach, the three-field crossing is usually used.[Chinese Medical Equipment Journal.2011 , 32( 5) : 59-61]关键词
