    • 摘要: 目的 基于AAPMTG-263实现宫颈癌放疗危及器官(OAR)和靶区命名标准化.方法 采用Matlab软件自编程实现放疗结构文件的读取与解析后,逐一自动输出、记录、存储每个子结构命名.对所有子结构命名统计整理后,以关键词对结构名进行归类.根据TG-263制定OAR和靶区标准命名转换表,并通过程序对归类后的结构名进行标准化处理.最后,输出标准化命名后的放疗结构文件,并导入计划系统.结果 144例宫颈癌患者的放疗结构均成功转化,并在放疗计划系统中正确显示.转化前OAR和靶区的命名缺乏统一的规范与标准,同一结构的命名存在较大的差异;转化后将43种OAR、74种靶区的命名方式分别规范统一成20种与8种,方便工作人员的理解与沟通.结论 实现宫颈癌放疗结构命名标准化,可减少命名的不一致性,并为盆腔肿瘤命名标准化提供参考.

    • 摘要: Objective To compare the effect of different therapeutic methods upon the survival of stage Ⅰ-Ⅱ A cervical cancer patients with intermediate risk factors and explore the optimal treatment for patients with early-stage cervical cancer undergoing radical hysterectomy and pelvic lymphadenectomy.Methods Clinical data of 323 patients with the following intermediate risk factors of lymphovascular space invasion,depth of stromal invasion or tumor size > 4 cm were retrospectively analyzed.The impact of observing (NT),chemotherapy (CT),radiotherapy (RT) and concurrent chemoradiotherapy (CCRT) on survival was statistically compared.The Kaplan-Meier method was used to survival analysis,and log-rank test difference,Cox model was used to prognostic factor analysis.Results The 5-year progression-free survival (PFS) and overall survival (OS) of all patients were 79.0% and 84.8%.Univariate and multivariate analyses demonstrated that TS> 4 cm and therapeutic method were the independent prognostic factors of PFS.The number of risk factors and therapeutic method were the independent prognostic factors of OS.In the whole group,both RT and CCRT could improve the prognosis of patients with no statistical significance (P>0.05).In the subgroup analysis,for patients with a single intermediate risk factor (low risk group),CT could significantly prolong the PFS (P=0.026) rather the 5-year OS (P=0.692).Compared with NT and CT,RT and CCRT could improve the PFS and OS,whereas no statistical significance was noted between the RT and CCRT (both P>0.05).For those with ≥2 risk factors (high risk group),CCRT could significantly prolong the PFS compared with CT (84.9% vs.70%;P=0.006),but did not improve the OS (P=0.107).Compared with RT,CCRT could significantly improve the PFS and OS (both P<0.05).Conclusion For patients with only one risk factor,RT can enhance the clinical prognosis.CCRT can improve the clinical prognosis of stage Ⅰ-Ⅱ A cervical cancer patients with ≥ 2 risk factors.%目的 比较不同治疗方式对伴中危因素的Ⅰ-ⅡA期宫颈癌患者的生存差异,探讨早期宫颈癌术后伴中危因素患者的最佳治疗模式.方法 回顾分析2007-2016年间收治的包含中危因素的323例宫颈癌术后患者,比较观察(NT)、单纯化疗(CT)、放疗(RT)及同步放化疗(CCRT)方式对生存的影响.Kaplan-Meier法生存分析,Logrank检验差异,Cox模型行预后因素分析.结果 全组的5年PFS、OS为79.0%、84.8%.单因素及多因素分析肿瘤大小>4 cm、治疗方式是影响PFS的因素(P=0.017、0.002),危险因素个数、治疗方式是影响OS的因素(P=0.042、0.000).全组中RT及CCRT均可改善患者预后(P=0.007、0.000).亚组分析中任意1个中危因素(低危组),CT能够延长5年PFS (P=0.026),在改善5年OS上相近(P=0.692);与NT及CT相比,RT及CCRT均能改善患者预后(P=0.006、0.000),但RT与CCRT相近(P=0.820、0.426).≥2个中危因素(高危组)中,与CT相比,CCRT能提高患者的5年PFS (P=0.006),但不能延长患者5年OS (P=0.107);RT与CCRT比较,CCRT均可改善患者的预后(P=0.028、0.039).结论 仅有1个中危因素时,RT也能改善预后;伴有≥2个中危因素时,CCRT更能改善患者的预后.

    • 摘要: Objective To investigate the relationship between the body mass index (BMI)/body mass index improved (BMIIMPd) and the dose of the small intestine as well as the acute radiation colitis in the intensity-modulated radiation therapy after cervical cancer surgery.Methods Thirty-nine cervical cancer patients underwent postoperative adjuvant radiotherapy.All patients received Philips large bore CT scan for enhanced CT scan,target delineation and organ at risk.All patients were treated with a single arc 10 MV VMAT plan.The correlation between the radiation dose of the small intestine and the acute radiation enteritis and BMI/BMIIMPd was analyzed.Results The BMI was calculated as (22.23±2.80) kg/m2,BMIIMPd was (21.49±3.95) kg/m2,the small intestine volume VSI was (1 155.71 ± 419.33)cc3.The volume of the small intestine received more than 10 Gy (V10_SI) VMAT was (66.50± 27.01) %,and the equivalent uniform dose (EUD) and normal tissue complication probability (NTCP) were (4 098.87± 184.93) cGy and (7.98±8.73)%.One way ANOVA demonstrated that under the VMAT technology,the BMIIMPd,V30,V40,EUD (or=50) and NTCP in the small intestine were the influencing factors of the occurrence of acute radiation enteritis.Conclusions If the improved BMIIMPd is utilized to distinguish the BMI,the high dose area of the small intestine will be larger and the incidence of acute radiation enteritis will be higher for patients with BMIIMPd between 10.1 and 16.9(normal and thin).Conventional BMI cannot be utilized as a basis for the prediction of the incidence of acute radiation enteritis in patients with cervical carcinoma.%目的 探讨宫颈癌术后辅助放疗患者常规体质量指数(BMI)和改进体质量指数(BMIIMPd)与小肠受照剂量和急性放射性小肠炎的相关性.方法 选取2017年接受宫颈癌手术后行辅助放疗的39例宫颈癌患者(其中杭州市肿瘤医院22例、温州市中心医院17例).全部患者行CT增强扫描,勾画靶区和危及器官范围.采用单弧,能量为10 MV的容积旋转调强放疗(VMAT)计划.观察小肠的受照剂量和急性放射性小肠炎与BMI和BMIIMPd的相关性.结果 BMI为(22.23±2.80)kg/m2,BMIIMPd为(21.49±3.95) kg/m2,小肠体积VSI为(1 155.71±419.33) cc3.VMAT计划下小肠V10为(66.50±27.01)%,等效均衡剂量(EUD)和正常组织并发症发生率(NTCP)分别为(4 098.87±184.93) cGy和(7.98±8.73)%.单因素方差分析结果显示,VMAT技术下BMIIMPd和小肠V30、V40、EUD(α=50)及NTCP是急性放射性小肠炎发生的影响因素.结论常规BMI指数不能简单作为患者急性放射性小肠炎发生概率预测的依据.应用BMIIMPd进行亚组分析时,如果该指数在10.1~16.9之间(正常和偏瘦型),小肠的高照射剂量区较大,急性放射性小肠炎发生率较高,因此推荐采用VMAT技术进行计划设计优化.
