目的探讨三维适形放疗在治疗晚期腹部恶性肿瘤上的临床疗效,并观察分析影响近期疗效的主要因素。方法选取了2010年6月-2012年6月我院收治诊断为晚期腹部恶性肿瘤共50例,对其给予三维适形放疗,其中每次照射的剂量为350-400cGy,每周3-5次,在放射治疗结束后对患者的肿瘤结构组织及病灶进行检查分析。结果在结束放射治疗后对患者肿瘤组织的情况进行分析检查,结果发现有3例患者得到完全的治愈,症状完全缓解,占6%;症状部分缓解的7例,占14%;经过治疗病情稳定的为26例,占52%;肿瘤进一步扩散恶化患者为14例,占28%。统计发现通过放射治疗的总有效率为72%。结论在晚期腹部恶性肿瘤的治疗上,采取三维适形放疗的方法可以抑制肿瘤的进一步恶化,缓解相关的症状,从而帮助患者实现有效的恢复,提高生存的治疗及生存率。而在近期疗效上来看,放疗剂量的大小是影响腹部恶性肿瘤放疗效果的重要影响因素。
Objective To investigate the clinical efficacy of three-dimensional conformal radiotherapy in the treatment of advanced malignant tumors of the abdomen and to observe and analyze the main factors affecting the short-term curative effect. Methods From June 2010 to June 2012, 50 cases of advanced abdominal malignant tumors were treated in our hospital. Three-dimensional conformal radiotherapy was given to them. The dose of each irradiation was 350-400cGy and 3-5 times a week , After the end of radiotherapy on the patient’s tumor structure and lesion examination and analysis. Results After the end of radiation therapy, the patients’ tumor tissues were analyzed and examined. Three patients were completely cured and the symptoms were completely relieved (6%). Seven patients (14%) were partially relieved of symptoms. After treatment, their symptoms were stable Of 26 cases, accounting for 52%; further spread of malignant tumors in 14 cases, accounting for 28%. Statistics found that the total effective rate of radiation therapy was 72%. Conclusion In the treatment of advanced abdominal malignant tumors, the use of three-dimensional conformal radiotherapy can inhibit the further deterioration of the tumor and relieve the related symptoms, so as to help patients achieve effective recovery and improve survival treatment and survival rate. In the near future, the size of the radiation dose is an important factor affecting the radiotherapy effect of malignant tumors of the abdomen.
