摘要
目的探讨控制饮水在提高宫颈癌患者放射治疗的精确度、减少膀胱炎直肠炎发生率中应用的可行性。方法将126例宫颈癌患者随机分为观察组和对照组,每组63例,两组均行外照射联合后装放射治疗。观察组在治疗前排空膀胱,饮500 ml水,1 h后治疗;对照组在治疗前嘱患者自行憋尿。观察两组放疗精确度、摆位误差以及并发症的发生情况。结果首次验证,观察组和对照组膀胱容积符合放疗精确度分别为95.7%和93.3%;对照组在X轴,Y轴二个方向上的摆位误差均较观察组增大(P<0.05),而两组在Z轴方向差异无统计学意义(P>0.05);观察组放射性直肠炎和放射性膀胱炎的发生率均显著低于对照组,两组比较差异有统计学意义(P<0.05)。结论宫颈癌放射治疗采用旋转治疗方式,并通过控制病人饮水,不但可以减小摆位误差,保证放疗精确度,还可减少患者膀胱炎的发生,提高患者的生存质量。
Objective To investigate water consumption control in increacing accuracy of radiotherapy and decreacing incidence of cystitis an proctitis of cervical cancer patients. Methods 126 cases of advanced cervical cancer patients were randomly divided into two group,observa-tion group and control group,63 cases in each group. The two group undertook external irradiation and after-loading therapy were recruited into our study. The observation group after emptying of bladder,taking 500 ml water,these patients undertook therapy in an hour. The control group before treatment patients were asked to self holding back. Precision radiotherapy,put a bit error occurrence and complications were observed. Re-sults The observation and control group of bladder volume consistent with radiotherapy accuracy were 95. 7% and 93. 3% for first time. Setup er-rors in control group in both X axis and Y axis direction was larger than those in control group（ P 〈0. 05）,and the differences in the Z axis were not statistically significant between two groups（ P 〉0. 05）. Incidence rate of radiation proctitis and radiocystitis showed significant difference be-tween the two groups. Conclusion VMAT employed in radiotherapy for cervical cancer combined with water consumption control could achieve well accuracy of radiotherapy,decrease incidence of cystitis and improve prognosis of cervical cancer patients.
