目的常规放射治疗传统技术联网数字化的研究应用可行性分析。方法选择2010年1月~2013年12月我院接诊的32例鼻咽癌患者进行研究,按照入院的时间顺序分为观察组和对照组。全部病例按规范化要求制定治疗计划。采用低熔点铅挡块、面颈联合野等中心照射技术。鼻咽根治剂量68~70 Gy/7周,颈淋巴结阳性者颈部根治剂量60~70 Gy/6~7周,阴性者给予预防剂量50 Gy/5周。观察组采用常规放射治疗传统技术联网数字化治疗技术,均根据CT和MRI对照射靶区进行个体化设计;而对照组采用传统常规放射治疗技术。在治疗后1个月,根据治疗前后头颈部CT肿瘤的变化情况进行客观近期疗效判定,统计治疗后1~3年的生存率。结果治疗后,观察组患者的总有效率93.75%高于对照组的62.5%,两组比较其差异具有统计学意义(P<0.05);观察组的鼻咽癌患者完全缓解(CR)5例,部分缓解(PR)10例,无变化(NC)1例,与对照组相比,差异具有统计学意义(P<0.05);两组患者比较治疗后的1年、2年、3年生存率,观察组的生存率分别为93.75%、81.25%、68.75%,而对照组为62.50%、43.75%、31.25%,两组比较其差异具有统计学意义(P<0.05)。结论采用常规放射治疗传统技术联网数字化技术,CT和MRI进行照射靶区的个体化设计,改进照射精度,提高照射剂量,加强放疗全过程的质量控制与质量保证,有助于提高鼻咽癌常规放疗的疗效。常规放射治疗传统技术联网数字化技术还有减少差错率、减少人力物力投入,节约成本、投资,省时省力等优点,值得广泛推广。
Objective To analyze the feasibility of traditional radiotherapy and conventional digital technology network. Methods From January 2010 to December 2013, 32 patients with nasopharyngeal carcinoma admitted to our hospital were studied, and were divided into observation group and control group according to the time sequence of admission. All cases according to standardized requirements for the development of treatment plans. The use of low melting point lead stopper, facial and neck union wild center irradiation technology. Nasopharyngeal radical dose of 68-70 Gy / 7 weeks, cervical lymph node positive of the neck radical dose of 60-70 Gy / 6-7 weeks, the negative were given a preventive dose of 50 Gy / 5 weeks. The observation group used conventional radiotherapy and conventional technology to digitize the therapy. All patients were individually designed according to CT and MRI, while the control group received conventional radiotherapy. At 1 month after treatment, according to the changes of head and neck CT tumors before and after the objective and short-term efficacy of the decision, the survival rate of 1 to 3 years after treatment. Results After treatment, the total effective rate in the observation group was 93.75% higher than that in the control group (62.5%). There was significant difference between the two groups (P <0.05); in the observation group, there were 5 cases of complete remission , Partial remission (PR) 10 cases, no change (NC) 1 case, compared with the control group, the difference was statistically significant (P <0.05); two groups of patients after treatment compared to 1 year, 2 years, 3 years survival The survival rates in observation group were 93.75%, 81.25% and 68.75% respectively, while those in control group were 62.50%, 43.75% and 31.25%, respectively. There was significant difference between the two groups (P <0.05). Conclusion Conventional radiotherapy conventional technology networking digital technology, CT and MRI of the individual target design of irradiation, improve the illumination accuracy, improve the radiation dose, enhance the quality control and quality assurance of the whole course of radiotherapy, will help to improve routine nasopharyngeal carcinoma The efficacy of radiotherapy. Conventional radiotherapy conventional technology networking digital technology also has the advantages of reducing the error rate, reducing manpower and material inputs, cost savings, investment, saving time and labor, etc., worthy of widespread promotion.
