摘要
目的了解中国外科医生对于直肠癌新辅助治疗后"等待观察"疗法的认知和态度以及治疗选择现况。方法采用横断面调查研究的方法。研究对象的选择:(1)全国范围内有结直肠癌诊疗资质、并设置有放疗科的公立三级甲等(省级和地市级)肿瘤专科医院或综合医院;(2)目标中心的副主任医师及以上的外科医生。采用"问卷星"网络调查平台创建关于直肠癌新辅助治疗后"等待观察"疗法的认知和态度以及治疗选择调查问卷,问卷内容包含医生基本信息、开展直肠癌手术现况、直肠癌新辅助治疗后病理完全缓解(ypCR)的处理现状、诊断临床完全缓解(cCR)的检查项目选择、"等待观察"适用人群选择、促使达到cCR的新辅助治疗模式和评效时点选择、"等待观察"的实施意愿和治疗选择以及"等待观察"的风险和监测等32个问题,通过微信向调查对象发送问卷链接,2019年1月31日至2月19日,共发出问卷116份。采用Fisher确切概率法进行组间比较。结果共纳入48家医院,在入选医院中筛选116名副主任医师及以上职称的外科医生,共有77名医生填写了本次调查问卷,应答率66.4%。已开展"等待观察"疗法的医生占76.6%(59/77);有90.9%(70/77)的医生知晓本单位直肠癌nCRT后的ypCR率;有63.6%(49/77)的医生知晓本单位ypCR患者的3年无病生存率(DFS);有71.4%(55/77)的外科医生认为,ypCR患者接受根治手术符合诊疗规范,不属于治疗过度。在诊断cCR的必要检查项目中,占前3位的分别为结肠镜(96.1%,74/77)、直肠指诊(90.9%,70/77)和直肠扩散加权成像核磁共振(83.1%,64/77)。关于倾向于实施"等待观察"的基线参考指标,被纳入选择的前3位为mrN0(77.9%,60/77)、mrT2(68.8%,53/77)和病理高分化腺癌(68.8%,53/77)。有85.7%(66/77)的医生认为,应该首选长程放化疗(LCRT)联合或不联合诱导和(或)巩固CapeOX方案(卡培他滨+奥沙利铂)作为促使达到cCR的新辅助治
Objective To understand the perceptions, attitudes and treatment selection of Chinese surgeons on the "watch and wait" strategy for rectal cancer patients after achieving a clinical complete response (cCR) following neoadjuvant chemoradiotherapy (nCRT). Methods A cross-sectional survey was used in this study. Selection of subjects:(1) Domestic public grade III A (provincial and prefecture-level) oncology hospitals or general hospitals possessing the radiotherapy department and the diagnosis and treatment qualifications for colorectal cancer.(2) Surgeons of deputy chief physician or above. Using the "Questionnaire Star" online survey platform to create a questionnaire about cognition, attitude and treatment choice of the "watch and wait" strategy after cCR following nCRT for rectal cancer. The questionnaire contained 32 questions, such as the basic information of doctor, the current status of rectal cancer surgery, the management of pathological complete remission (ypCR) after nCRT for rectal cancer, the selection of examination items for diagnosis of cCR, the selection of suitable people undergoing "watch and wait" approach, the nCRT mode for promotion of cCR, the choice of evaluation time point, the willingness to perform "watch and wait" approach and the treatment choice, and the risk and monitoring of "watch and wait" approach. A total of 116 questionnaires were sent to the respondents via WeChat between January 31 and February 19, 2019. Statistical analysis was performed using Fisher′s exact test for categorical variables. Results Forty-eight hospitals including 116 surgeons meeting criteria were enrolled, of whom 77 surgeons filled the questionnaire with a response rate of 66.4%."Watch and wait" strategy was carried out in 76.6%(59/77) of surgeons. Seventy surgeons (90.9%) were aware of the ypCR rate of rectal cancer after preoperative nCRT and 49 surgeons (63.6%) knew the 3-year disease-free survival of patients with ypCR in their own hospitals. Fifty-five surgeons (71.4%) believed that patients with ypCR
