Analysis of the isocenter deviation in radiotherapy field of rectal cancer patients in post-operative three-dimensional conformal radiotherapy
Objective To evaluate the isocenter deviation in radiotherapy field of rectal cancer patients in post-operative three-dimensional conformal radiotherapy.Methods Thirty rectal cancer patients receiving post-operative three demensional conformal radiotherapy were analyzed.All patients were immobilized with the thermoplastic mask and received three-dimensional conformal radiotherapy.The isocenter was marked before 1st and 20th fraction of radiotherapy using CT simulation.The [...]

Three dimensional conformation radiotherapy for 35 cases of unresectable massive primary liver cancer
Objective To evaluate the effect of three dimensional conformation radiotherapy(3-DCRT)for unresectable primary massive liver cancer.Methods From October 1997 to June 2008 35 unresectable massive primary liver cancer patients were analyzed,the tumor size were 8-12cm,including Child-Pugh Grade A and B respectively.The patients received 3-DCRT with total dose of 50-55 Gy,at 4-5 Gy/f,3f/w.Results The CR was 17.1%,PR [...]
