Objective:To discuss the feasibility of using online and offline combined multidisciplinary team (MDT) diagnosis-treatment mode in cancers diagnosis and treatment by comparing the comprehensive diagnosis and treatment plans formulated by online and offline MDT diagnosis-treatment mode.Methods:A total of 168 esophageal cancer patients collected from March 17, 2020 to May 17, 2020 were took as the research objects in Shandong Cancer Hospital and Institute, through whom the consistency of the comprehensive diagnosis and treatment plans formulated by online and offline MDT diagnosis-treatment mode was evaluated. The clinical characteristics of patients with changed comprehensive diagnosis and treatment plans, such as age, Karnofsky performance status (KPS) score, whether combined with basic diseases, whether received anti-tumor treatment before and tumor location were analyzed, so as to explore the mechanism to improve the efficiency on the basis of quality assurance.Results:The results showed that 86.3% (145/168) of the comprehensive diagnosis and treatment plans obtained by offline MDT diagnosis-treatment mode were consistent with online diagnosis-treatment MDT mode. Cases with inconsistent comprehensive diagnosis and treatment plans were characterized by elderly (> 69 years) ( χ2=4.250, P=0.039), KPS score≥80 ( χ2=15.520, P<0.001) and combined with underlying disease ( χ2=7.135, P=0.008). Through further analysis, the changed cases were also characterized as with inadequate auxiliary examination or complex in imaging. Conclusion:The online and offline combined MDT diagnosis-treatment mode is feasible. For the patients characterized of elderly (> 69 years old), KPS score ≥80, combined with underlying diseases, with incomplete auxiliary examination or complex in imaging, the offline MDT diagnosis-treatment mode should be adopted or supplemented.

头颈部肿瘤是常见的恶性肿瘤之一,放射治疗不仅治疗效果理想,还可保留患者的容貌及功能,故在头颈部肿瘤的治疗中发挥了重要的作用.螺旋断层放射治疗(helical tomotherapy,HT)是近十年发展起来的一种新的调强适形放疗技术,目前已初步用于鼻咽癌、口咽癌等多种头颈部肿瘤的治疗.与常规加速器调强放疗相比,螺旋断层放疗在放疗靶区的剂量覆盖及危及器官的保护等方面具有一定优势.
