- W2363844982 abstract "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 isocenter layer and the superior and inferior 5 layers were scanned.The deviations of various directions were measured by comparing the isocenter of reconstructed CT and marked in TPS(treatment planning system).The influences of different positions,operative styles and genders on the isocenter deviation were analyzed.The deviations of 1st and 20th fractions of radiotherapy were compared too.Results The deviations of left-right,cranio-caudal and anterior-posterior direction of female and male patients were(4.4±4.3)mm and(3.8±3.7)mm(P=0.40),(4.9±4.7)mm and(4.2±3.1)mm(P=0.03) and(5.1±2.7) mm and(3.9±2.9)mm(P=0.002).The deviations of left-right,cranio-caudal and anterior-posterior direction of supine and prone positions were(3.3±2.7)mm and(3.8±2.7)mm(P=0.17),(3.9±2.7)mm and(4.3±3.9)mm(P=0.30)and(3.2±2.2)mm and(4.1±3.5)mm(P=0.39).The deviations of left-right,cranio-caudal and anterior-posterior direction of Dixon′s and Mile′s were(3.2±3.6)mm and(4.3±2.7)mm(P=0.04),(3.9±2.3)mm and(4.9±4.7)mm(P=0.02)and(3.3±3.4),(4.7±3.7)mm(P=0.001).The deviations of left-right,cranio-caudal and anterior-posterior direction of 1st and 20th fraction during radiotherapy were(3.3±2.5)mm and(4.4±3.5)mm(P=0.06),(3.7±3.9)mm and(5.3±4.3)mm(P=0.19),and(3.1±2.7)mm and(5.4±2.5)mm(P=0.15).Conclusion The isocenter deviation in radiotherapy for rectal cancer patients could be precisely analyzed using CT simulation.The differences of isocenter deviations between different genders and operative styles are substantial,but differences between supine and prone orientation are small.The isocenter deviation becomes larger during the later radiotherapy." @default.
