1.随机分组:拟收治400例局部晚期鼻咽癌患者(T3-4,N0-3,M0,AJCC分期第8版),随机分为2组:解剖影像为基础的IMRT组(解剖影像组、A组或对照组)和DW-MRI引导的SIB-IMRT组(DW-MRI组、B组或试验组),各组200例患者。 2.治疗方案 2.1治疗方案参考美国国立综合癌症网(National Comprehensive Cancer Network, NCCN)指南2018年第1版。患者接受诱导化疗+同步放化疗,或同步放化疗+辅助化疗。同步放化疗方案:顺铂 100mg/m2,每3周一次,共3次。诱导化疗为3周期TPF方案:多西他赛60 mg/m2,第1天,顺铂60 mg/m2,第1天,氟尿嘧啶600 mg/m2/天,120小时(第1-5天)持续泵入。辅助化疗(3周期PF方案):顺铂80 mg/m2,第1天, 氟尿嘧啶800 mg/m2/天,120小时(第1-5天)持续泵入。 2.2放射治疗 所有患者均行CT模拟定位、疗前鼻咽+颈部MRI检查,采用3.0T 超导型磁共振扫描仪,扫描序列包括T1加权、T2加权、T1增强、弥散加权, DWI 采用单次激发 SE-EPI 序列,b 值取1000s/mm2。定位CT和MRI间隔时间不超过5天。行计划性诱导化疗缓和,在诱导化疗后再次行定位CT及MRI。全部患者均接受调强放射放疗,靶区勾画及放疗剂量参考肿瘤放射治疗协作组织(RTOG)0615研究、RTOG 0225研究及中国2010鼻咽癌调强放疗靶区及剂量设计指引专家共识。试验组及对照组均在CT/MRI融合图像上勾画靶区,试验组参考MRI的T1加权、T2加权、T1增强及DWI,对照组参考MRI的T1加权、T2加权及T1增强,两组靶区均包括GTVnx(原发肿瘤)、PGTVnx、GTVnd(转移淋巴结)、临床靶区CTV1、CTV2、计划靶区PTV1、PTV2,试验组的GTVnx、GTVnd需包括DW-MRI相应高信号区,并在表观弥散系数(apparent diffusion coef?cient,ADC)图像上(b值800 s/mm2)勾画GTVnx内小于ADC均值(ADCmean)区域为GTVnx-ADC (ADC均值的计算:在ADC图上选取GTV最大层面作为感兴趣区(region of interest, ROI),每个 ROI测量ADC值多次,取其平均值)。放疗10次、18f时两组患者均重新CT模拟定位及MRI检查(MRI参数同前),根据肿瘤变化情况调整上述靶区。靶区剂量:对照组:PGTVnx 72.6Gy(2.2Gy/f×33次),GTVnd 69.96-72.6Gy(2.12-2.2Gy/f×33次),PTV1 60.06-62.7Gy(1.82-1.9Gy/f),PTV2 50.96-56Gy(1.82-2.0Gy/f);DW-MRI剂量雕刻组:采用同步加量(SIB)的剂量雕刻调强放疗技术, PGTVnx-ADC 总剂量提升至77.55Gy,单次剂量提升至2.35Gy,余靶区剂量(PGTVnx、GTVnd、PTV1、PTV2)同对照组。放疗完成后评价患者两组的治疗反应及急性毒性反应。 3.随访,疗效及毒性反应评价 3.1 放疗结束后3月复查鼻咽及颈部MRI、电子鼻咽喉镜、胸片或胸部CT、腹部超声、全身骨显像、血浆EBV-DNA水平、血常规、血生化等,评价近期治疗反应(完全缓解率、部分缓解率等)及急性毒性。随访3-5年(治疗结束后2年内每隔3个月复查一次;第3-5年每半年复查一次;第6年开始每年复查一次;如病情变化随时就诊),评价各组的远期疗效:主要观察指标为总生存率(OS),次要观察指标为局部无复发生存率(LRFS)、区域无复发生存率(RRFS)、局部区域无复发生存率(LRRFS)、无远转生存率(DMFS)、无瘤生存率(DFS)等)及急性和晚期毒性反应,评价DW-MRI引导的SIB调强放疗较基于解剖影像的IMRT是否较可以改善局部晚期鼻咽癌的长期生存且不增加毒副反应;并分析血浆EBV-DNA水平对IMRT和DW-MRI引导的SIB-IMRT疗效的影响。评价血浆EBV-DNA水平、DW-MRI引导的SIB剂量雕刻IMRT技术是否是影响患者预后的独立因素,建立局部晚期鼻咽癌的预后模型。 3.2 EBV-DNA定量:应用荧光定量PCR技术,检测两组患者治疗开始前、治疗中(第2周、第4周)治疗结束时、随访中的血浆EBV-DNA水平。 4. 统计分析:应用SPSS 20.0进行统计分析,应用卡方检验比较两组间的患者特征(年龄、性别、分期等)、毒性反应、治疗反应。Kaplan-Meier法分析生存率,log-rank test法比较两组间的生存差异。多因素分析检验预后因素,分析的因素包括:患者血浆EBV-DNA水平、年龄、性别 (男 vs 女)、T分期 (T3 vs T3)、N分期(N0-1 vs N2-3)、DW-MRI引导的SIB-IMRT vs 基于解剖影像的IMRT;P小于0.05为有统计学差异。 |

Description for medicine or protocol of treatment in detail: |
1.Randomisation
We plan an open-label, randomised controlled trial at Hunan Cancer Hospital in China. Four hundred patients with previously untreated, locally advanced (stage T3-4N0-3M0AJCC 8th) nasopharyngeal carcinoma are enrolled. Eligible patients are randomly assigned (1:1) to DWI-guided SIB-IMRT group (group A) and anatomical image-based IMRT group (group B).
2.Treatment
2.1 Imaging
All the patients enrolled in the study underwent both pre-treatment contrast-enhanced CT and MRI. The planning CT scan and MRI exam were performed within 5 days. In patients who received induction chemotherapy, CT simulation and MRI after induction chemotherapy were required. The scope of CT simulation scan from the top of the head to the manubriosternal joint was scanned at 2.5-mm increments.
The MRI scans used in this study were transversal T1-weighted MRI and the DWI images, both part of the standard clinical MRI protocol. The T1-weighted MRI was acquired with a 3D turbo field echo (TFE) technique with gadolinium enhancement. The DWI images were acquired using single-shot spin-echo echo-planar imaging (EPI), and the b-values were 0 and 1000 s/mm2. The ADC map was calculated on the scanner. T1-weighted MR images were fused to the CT simulation images in both groups. In group A, DWI images ( b-values = 0 and 1000 s/mm2) were also fused to the CT simulation images. For this study, MR images were registered to the planning CT using Pinnacle inverse planning system with a region of interest defined around the GTV.
2.2 Eligible patients are scheduled to receive induction chemotherapy plus concurrent chemoradiotherapy or concurrent chemoradiotherapy plus adjuvant chemotherapy, according to the National Comprehensive Cancer Network (NCCN) guidelines. Concurrent chemotherapy was prescribed as three cycles of 100 mg/m2 cisplatin every 3 weeks, concurrently with IMRT. Induction chemotherapy is three cycles of intravenous docetaxel (60 mg/m2 on day 1), intravenous cisplatin (60 mg/m2 on day 1), and continuous intravenous fluorouracil (600 mg/m2 per day from day 1 to day 5) every 3 weeks before concurrent chemoradiotherapy. Adjuvant chemotherapy is is three cycles of intravenous cisplatin (80 mg/m2 on day 1), and continuous intravenous fluorouracil (800 mg/m2 per day from day 1 to day 5) every 3 weeks after concurrent chemoradiotherapy.
2.3 Radiotherapy
For the ADC, an often used measure to report ADC values within a tumor is the mean ADC in a region. Additionally, a low ADC is indicative of tumor presence, but a higher ADC within the tumor is associated with worse outcome. Therefore, we segmented the areas within the GTVnx with an ADC below the mean ADC (ADC |
