摘要
目的分析宫颈癌三维后装治疗中膀胱充盈状态对直肠受量、膀胱的影响。方法选择2016年3月至2018年2月在本院接受治疗的宫颈癌患者98例,按照膀胱体积将其分成3组,<60 cm^3组(A组)、60~90 cm^3组(B组)、>90 cm^3组(C组),在D90及V100条件下,统计直肠及膀胱0.1 cm^3、2 cm^3受量数据,并比较组间差异。结果A、B直肠及膀胱0.1 cm^3、2 cm^3受量均显著低于C组,差异均有统计学意义(P<0.05),A组及B组间数据差异有统计学意义(P<0.05)。随访3个月,C组治疗总有效率稍高于其他两组,放射性肠炎及膀胱炎发生率稍低于其他两组,差异无统计学意义。结论在宫颈癌患者的放疗过程中,膀胱充盈程度与直肠、膀胱受量间存在一定的关联。膀胱尽量避免充盈至>90 cm^3,以减少直肠及膀胱受量。
Objective To analyze the effect of bladder filling state on rectal weight and bladder in three-dimensional post-loading treatment of cervical cancer.Methods A total of 98 patients with cervical cancer who were treated in our hospital from March 2016 to February 2018 were enrolled.The patients were divided into three groups according to the bladder volume,<60 cm3 group(group A),60-90 cm^3 group(group B),and >90 cm^3 group(Group C),under the conditions of D90 and V100,the data of 0.1 cm^3 and 2 cm^3 of rectum and bladder were counted,and the differences between groups were compared.Results The doses of 0.1 cm^3 and 2 cm^3 in A and B rectum and bladder were significantly lower than those in group C(P<0.05).The difference between group A and group B was statistically significant(P<0.05).After 3 months of follow-up,the total effective rate of group C was slightly higher than that of the other two groups.The incidence of radiation enteritis and cystitis was slightly lower than the other two groups,and the difference was not statistically significant.Conclusion In the course of radiotherapy for patients with cervical cancer,there is a certain correlation between the degree of bladder filling and the rectal and bladder dose.The bladder should be prevented from filling to >90 cm^3 to reduce rectal and bladder weight.
