颈胸上段食管癌两种固定方式放疗摆位误差的对比研究
Contrastive study of radiotherapeutic positioning errors between two kinds of fixation modes in cervical and upper-tho-racic esophageal cancer
摘要
Abstract
Objective To investigate the radiotherapeutic positioning errors between using the fixation modes of cervical shoulder film and body film by using the cone beam CT (CBCT ) in cervical and upper thoracic esophageal cancer to provide a reference for a better choice of clinical treatment .Methods 66 cases of cervical and upper thoracic esophageal cancer undergoing radiotherapy were randomly selected and equally divided into the group A and B .The group A adopted the thermoplastic neck and shoulder membrane fixation in positioning ,while the group B adopted the thermoplastic body membrane fixation .CBCT was used to measure the positioning errors before initial therapy in each case .The SPSS17 .0 software was used to perform the statistical analysis .Results The positioning errors from the directions of left‐right (X axial) ,superior‐inferior(Y ) and anterior‐posterior(Z) in the group A were (0 .20 ± 0 .14) ,(0 .15 ± 0 .15) ,(0 .23 ± 0 .15)cm respectively ,and which in the group B were (0 .16 ± 0 .13) ,(0 .24 ± 0 .16) , (0 .18 ± 0 .12)cm respectively ,the errors data in the group A were superior to those in the group B ,especially which in the head and feet had statistical significance(P<0 .05) .Conclusion The cervical shoulder membrane fixation tech‐nology can reduce the radiotherapeutic positioning errors during radiotherapy in the patients with cervical and upper thoracic esophageal cancer ,its operation is easy and feasible ,which is worth further clinical promotion and application .关键词
