目的探讨宫颈癌普通放疗中应用ORFIT架固定的临床作用与意义。方法 58例宫颈癌患者,将其按照入院顺序分为观察组和对照组,每组29例。观察组患者放疗中应用ORFIT架固定,对照组放疗中使用真空垫固定,每位患者经过3次放疗后对比患者放疗中ORFIT架与真空垫使用的临床意义。结果观察组小肠、膀胱照射体积为(16.0±2.6)mm3、(6.0±2.2)mm3、(69.0±12.2)mm3和(44.0±7.9)mm3,与对照组的(19.0±3.8)mm3、(11.0±4.5)mm3、(77.0±7.2)mm3、(66.0±7.8)mm3相比占显著优势,差异有统计学意义(P<0.01)。结论宫颈癌普通放疗摆位中应用ORFIT架固定可以有效减少小肠和膀胱受射线照射剂量的体积,可在临床上推广应用。
Objective To investigate the clinical effect and significance of ORFIT fixation in radiotherapy of cervical cancer. Methods 58 cases of cervical cancer patients, according to the order of admission were divided into observation group and control group, 29 cases in each group. The patients in the observation group were treated with ORFIT fixation during radiotherapy and the control group were treated with vacuum pad. Each patient underwent 3 times radiotherapy to compare the clinical significance of ORFIT and vacuum pad in radiotherapy. Results The volume of small intestine and bladder irradiation in the observation group was (16.0 ± 2.6) mm3, (6.0 ± 2.2) mm3, (69.0 ± 12.2) mm3 and (44.0 ± 7.9) mm3, ± 4.5 mm3, (77.0 ± 7.2) mm3 and (66.0 ± 7.8) mm3, respectively, with significant difference (P <0.01). Conclusion The application of ORFIT fixation in cervical cancer radiotherapy can effectively reduce the volume of radiation dose of small intestine and bladder and can be widely applied in clinic.
